Abstract:

The toxic optic neuropathies are typically characterized by subacute or chronic, bilateral, symmetrical and painless loss of vision. Treatment is initiated by recognition and drug withdrawal. Historically, methanol (though not a medication), ethambutol and isoniazid were the first to be recognized as neurotoxic. Later, cyclosporine, a widely used immunosuppressant and other chemotherapeutic agents, like; cisplatin, carboplatin and vincristine were recognized as having neurotoxic adverse reactions. Amiodarone-associated optic neuropathy has been widely discussed in the ophthalmic literature less than half a century ago. It is still controversial whether sildenafil and other phosphodiesterase-5 inhibitors prescribed for erectile dysfunction, cause visual loss by triggering ischemic optic neuropathy. Vigabatrin, used around the world as an anti-epileptic drug, was reported to cause irreversible visual field defects in children. Infliximab, an anti-tissue necrosis-alpha monoclonal antibody currently in use for granulomatous diseases, is also known to cause toxic optic neuritis. A long list of reported drugs is associated with increased intracranial pressure, though not confirmed by controlled studies. Vitamin A derivatives, corticosteroids, tetracyclines, fluoroquinolones, gonadal hormones, indomethacin, lithium and tamoxifen are just a small part of this list. Abnormalities of eye movements, including nystagmus and inappropriate vestibulo-ocular reflex are reported at toxic levels of neuroactive drugs like: diazepam, methadone, phenytoin, barbiturates and chloral hydrate. Drug-induced disturbances of neuromuscular transmission, occurring at the pre-or-post synaptic levels, include prominent ptosis and ophthalmoparesis along with variable degrees of extremity muscle weakness resembling true myasthenia gravis.

Abstract:

Statement of the Problem: Ocular melanoma is a rare subset of melanoma, yet comprises the majority of ocular malignancies. Management of ocular melanoma consists of either enucleation or glob-preserving therapies including radiation therapy (RT) and surgical resection. There are generally two categories RT for ocular melanoma, radioactive plaque brachytherapy and external beam radiotherapy (EBRT), including charged particle radiation and photon stereotactic radiosurgery (SRS). In this presentation we give an overview of the technical details and clinical efficacies of different RT techniques for ocular melanoma. In an effort to reduce the invasiveness without compromising accuracy, we developed a novel approach of real-time tracking to ocular tumors that can be applied to high-precision RT either with charged particle or photon beams.

Methodology & Theoretical Orientation: A novel “pupil tracking” approach uses a derived 2D/3D transformation to relate the pupil’s 2D coordinate captured by a video camera in the image plane with the tumor’s 3D location in the CT space. A motion phantom was development to test the feasibility of this technology with a robotic radiosurgery system.

Findings: The results show that the unique 2D/3D transformation algorithm is not only theoretically possible but also consistently reproducible with sub-millimeter accuracy.

Conclusion & Significance: Charged particle RT or SRS can eliminate invasiveness of brachytherapy. Pupil-based tracking can further assure the physical accuracy and achieve optimal clinical outcomes.

Abstract:

Background: Neonatal and early screening is aimed at the primary prevention of visually impairing disease (e.g. mainly premature infant require a consistent approach to screen them for Retinopathy of prematurity ROP). ROP is one of the few causes of childhood visual disability, which is largely preventable. The screening can as well detect other congenital blinding eye diseases like cataract or Glaucoma that can be treated to prevent permanent visual loss. In addition other diseases that can pick early may include the autosomal recessive inheritance disorders that are the causes for retinal dystrophies such as Retinitis Pigmentosa (RP) and Leber's congenital amaurosis (LCA). 

Method: A qualitative methodology approach is used. An in-depth interview sessions were conducted concentrating on specific topics related to Retinopathy of prematurity (ROP).

Participants: The in-depth sessions consisted of three ophthalmologists working in Dubai, with extensive knowledge about vision programs and services.

Setting: Three sessions were performed during January- June 2017.

Key findings:

1. Retinopathy of prematurity (ROP) is one of the few causes of childhood visual disability which is largely preventable. Many extremely preterm babies will develop some degree of ROP, which usually resolves spontaneously without treatment. A small proportion, develop potentially severe ROP which can be detected through retinal screening. If untreated, it can result in serious vision impairment. Therefore, all babies at risk of sight-threatening ROP should be screened.

2. Among children, Retinopathy of Prematurity (ROP) is potentially blinding eye disorder that primarily affects premature infants. The estimated prevalence is about 10% among premature infants annually develop ROP and about 1–2% that are severe enough to require medical treatment. There is no follow up studies in Dubai to show how many of these each year become blind from ROP.

3. Currently different hospitals used different international guidelines to tackle ROP. However, A local Guideline for the Screening and Treatment of Retinopathy of Prematurity (ROP) is required to set up the standards and criteria when ROP should be screened.

Abstract:

Lipofuscin, a byproduct of the vision cycle of photoreceptors, is the major source of the fundus auto-fluorescence (FAF) in the Retinal Pigment Epithelium (RPE). Lipofuscin accumulates with aging and in certain pathological disorders and is thus a biomarker for degenerative retinal diseases. Therefore, quantification of lipofuscin is important in the diagnosis, progression monitoring, and treatment evaluation. Lipofuscin quantification is challenging because light is attenuated by the media anterior to the RPE which is subject to inter-individual and intra-individual differences. Further, various illumination power and detection sensitivity of different imaging systems can also affect the readings of the detected FAF.

We developed a technology to provide simultaneous VIS-OCT and AF of the retina and a reference standard target at the intermediate retinal imaging plane with a single broadband visible light source. Since both OCT and AF images are generated from the same group of photons the OCT probe light experiences attenuation by the same ocular layers. The technology is able to eliminate the varying pre-RPE attenuation factor in AF imaging using the simultaneously acquired VIS-OCT image. To quantitatively bridge the OCT and AF detection systems thus eliminate the effects of illumination power and detector sensitivity, a standard reference target with known reflectivity and fluorescence efficiency was implemented into the system. Using the standard reference, similar to the one used by Delori AF and reflectance signals are normalized to a known reference value that are independent from the exposure power and detection gain. The system was calibrated and tested in vivo.

Abstract:

Problem: The ministry of health in Singapore has recently announced an initiative to change the landscape of healthcare from hospital to community care and from quality care to value driven care. This necessitates a change in the way ophthalmologists and optometrists manage patients.

Methodology: In this presentation I will elaborate on various initiatives we have embarked upon to fulfil the ministry of health’s directives. This includes training of hospital optometrists, engaging community optometrists, virtual clinics, establishing fit-for-purpose eye centres in the community and rationalising the movement of eye patients around the island such that they are seen by the right level of professional, in the right place and at the right time. Similar models of care that have already been established in UK will be described for comparison.

Findings: Models of care that have already been established will be described and data presented on patient outcomes including patient experience, safety and effect on the hospital eye service. Theoretical approaches to collaborations between optometrists and ophthalmologist will be discussed and an interactive question and answer session is anticipated.

Conclusions: I hope to expound some ideas of collaborations between optometrists and ophthalmologists that draw upon the strengths of each such that patient care remains high quality but with greater value.

Abstract:

Introduction: Glaucoma and Cataract often coexist in the same eye One of the accepted surgical options in patients with severe glaucoma and coexisting cataract is first to control the IOP with trabeculectomy and then extract the cataract several months later , or by cataract surgery alone when trabeculectomy is not indicated Recently, primary lens extraction alone gained more acceptance.

Purpose: To review the current ophthalmic literature regarding the impact of modern cataract surgery on intraocular pressure (IOP)

Materials and Methods: Study design: Hospital based, retrospective study conducted from November 2014 to March 2015.

Study population: Patients who had phaco surgery for cataract with coexisting POAG.

Sample size: 50 patients were selected according to inclusion criteria.

Study area: MAKKAH EYE COMPLEX; specialized ophthalmology Center, well equipped and serves patients from all over Sudan, with sub specialized ophthalmic services. Sample selection obtained from only one clinic twice a week.

Results: There were 50 patients, 29 Males and 21 females (Fig 1), underwent uneventful phacoemulsification surgery, 26 right eyes and 24 left eyes, 22 % were diabetic. The mean preoperative IOP was 21.3 mmHg 4.8 SD, mean 1 week postoperative IOP 20.4 mmHg 4.3 SD (P – value 0.08), one month 20.1 mmHg 3.7 SD (P – value 0.04), and two months 19.6 mmHg (P – value 0.01) The mean IOP reduction was 0.8 to 1.7 mmHg (P = 0.00). The mean number of preoperative ant glaucoma topical medications 2.1 drugs 0.7 SD, one week postoperative 1.6 drugs 0.9 SD (P-value 0.008), one month 1.58 drugs 0.78 SD (P-value 0.003), two months 1.44 drugs 0.7 SD (P-value 0.000)

Conclusion: In conclusion phaco induces significant intraocular pressure reduction in the short postoperative period in glaucomatous patients. Phaco can be performed with intent of achieving better IOP control. Glaucomatous patients may get benefit from phaco by decreasing the amount of topical anti glaucoma medications.

Background: Since LASIK was introduced about three decades ago, an estimated 28 million LASIK surgeries have been performed worldwide, and more than 500,000 of those surgeries were performed in Israel. Many of the patients who had refractive surgery 20 years ago have now reached the age of cataract surgery, and seek to continue their spectacle independence. However, patients who have had refractive surgery frequently experience increased optical aberrations, with the cornea itself often becoming multifocal in nature.  Placing a multifocal intraocular lens (MFIOL) IOL behind a multifocal cornea may run the risk of a reduction in visual quality.

Methods: This is a retrospective compression case series of the cataract surgeries implanted with a MFIOL. Data was abstracted on uncorrected and best corrected visual acuity (UCVA, BCVA). A comparison was made between naïve and post-refractive surgery eyes.

Results: We identified 1200 consecutive cataract surgeries: 800 were naïve eyes (group 1) and 400 had previous refractive surgery (group 2). All cataract surgeries were Femtosecond laser-assisted (Lensx or Victus) and performed by a single surgeon. All MFIOLs were manufactured by Fine Vision (Physiol). The formula used was the “Levinger Formula”, which is a modification of the SRKT formula. At 1 month postoperatively, the UCVA was 0.18 (log MAR) in group 1 and 0.23 in group 2 (p=0.1). At that time, there was a negative effect of age in both groups (r= 0.14 p= 0.04). Near UCVA was 2.01 in group 1 and 3.71 in group 2 (p<0.001). BCVA was 0.09 and 0.12 in group 1 and 2 respectively (p=0.06).

Conclusion: Implantation of a MFIOL in cataract surgery in eyes with previous refractive surgery is a viable option - achieving good distance UCVA, with the understanding that there is a slight limitation of near UCVA.

Abstract:

The duration of diabetes and glycaemic control is collective risk factors for severity and progression of diabetic retinopathy. Diabetic macular edema (DME) emerges as one of the leading causes of blindness. The incidence of diabetes and its retinal complications is increasing in a rapid pace especially in the gulf region. The treatment of DME has evolved from focal and grid laser photocoagulation as the gold standard of therapy for DME, as stated in the Early Treatment of Diabetic Retinopathy Study (ETDRS), yet, the evolvement of new modalities specially the intravitreal injection changed the paradigm of treatment of DME. New therapies has developed with proven efficacy like vascular endothelial growth factor inhibitors (VEGF) agents like Bevacizumab and Ranibizumab, VEGF and placental growth factor inhibitor like Aflibercept, Corticosteroid materials like Triamcinolone Acetonide, Dexamethasone and Fluocinolone Acetonide. A high volume of studies to support such modalities have been conducted including RISE and RIDE, RESOLVE , DRCR, RRESTORE, RETAIN, RELIGHT, VIVID, VISTA, CHAMPLAIN, ETC…. A review of the different results of these trials with different case reviews with the different modalities of treatment is to be presented and discussed.

Abstract:

Purpose: To evaluate the effect of a cross-linking under photorefractive ablation of the cornea saturated with riboflavin

Methods: Several studies on corneal collagen cross-linking (CXL) and secondary radiation induced by excimer laser ablation were reviewed. TransPRK, LASIK and FemtoLASIK were performed on 402 eyes with myopia and myopic astigmatism. Photorefractive ablation was performed after corneal stroma saturation with 0.25% isotonic riboflavin.  Follow-up varied from 1 month to 4 years. The effects of CXL were assessed by spectral-domain OCT and corneal densitometry

Results: CXL induced by photorefractive ablation with riboflavin is realized through the series of consecutive reactions of riboflavin activation. Activation of riboflavin with the secondary radiation induced by corneal ablation is considered as a trigger. Broad spectrum of the secondary radiation covers all four peaks of maximum riboflavin absorption at 223, 268, 374, and 445 nm. Cross-linking effect amplifies due to the secondary interaction of riboflavin with peroxyl radicals of the oxidative stress and aseptic inflammation in the stroma in response to photorefractive keratectomy. Corneal densitometry and anterior segment OCT demonstrate that CXL increases optical density of the residual stroma and enhances the absorption of external UV photons. This improves or compensates impaired mechanical and photo protective functions of the ablated cornea. Thin membrane-like Structure on the ablation surface as well as higher optical density of the corneal stroma adjacent to the ablation zone are revealed after TransPRK with riboflavin. In addition to the higher optical density of the corneal stroma, demarcation line of various intensity (which resolves later) is revealed after LASIK and FemtoLASIK.

Conclusions: The effect of crosslinking in photorefractive ablation with riboflavin was realized through the formation of a membrane-like structure on the ablation surface and was accompanied by an increase in the optical density in the layers of the stroma adjacent to the ablation zone

Key words: cross-linking, secondary excimer laser radiation, photorefractive ablation, riboflavin.

Abstract:

The tear film can be considered the first refractive layer of the eye; however, its importance has been not receiving the proper attention, especially before cataract and refractive surgeries. The accuracy of regular pre surgical investigations like keratometry and aberrometry can be hugely affected by the quality of the tear film. In addition, dry eye and other corneal and conjunctival problems can easily compromise the final refractive result even after a prestine uncomplicated surgery. In this presentation, I’ll bring evidence based data to convince the importance of the ocular surface proper assessment and management timely, including diagnosis tools and updated treatment of ocular surface most common diseases.

Abstract:

Statement of the Problem:  A lot of  countries around the world are still underserved by ophthalmologists. The expense of setting up an ophthalmology clinic is so high that majority of the population do not have access to ophthalmic services and investigations. In fact, instead of expanding. most medical centers prefer to forego opening satellite clinics that could have increased practice efficiency and revenue.

The purpose of this study is to show that there is a new online platform, called Saccadio Suites, that bridges the gap between the lack of ophthalmologists in distant locations and the availability of management systems that not only provide access to affordable ophthalmic tests and investigations but also could connect more patients to the clinic than ever before.

Methodology & Theoretical Orientation:  In order to give a clear picture of a patient’s eye condition, a powerful blend of structural and functional devices were used such as the Saccadio Web and Saccadio Haploscope, collectively known as the Saccadio Suites.

Discussion will center on the different devices in the Saccadio Web (structural tests) and the Saccadio Haploscope (functional tests). Each device will be briefly described and an overview given.

Conclusion: The Saccadio Suites help in the prevention of blindness by bridging the gap between the lack of ophthalmologists and ophthalmic services in remote areas. It increased the clinic’s efficiency by making very fast, accurate and comprehensive eye examination. The remote teleophthalmologist gets the report online, makes an immediate interpretation and decides on the treatment.

Recommendations: Most of the ophthalmic devices in the market today provide only structural tests but not the functional tests included in the Saccadio Haploscope.  It is, therefore, highly recommended that clinics and medical centers avail of Saccadio Suites which are integrated with artificial intelligence that can be automated to facilitate diagnosis and management of eye diseases.

Abstract:

Background: The prevalence of sight loss increases with age, and the Dubai population is ageing. In addition there is a growing incidence in key underlying causes of sight loss such as obesity and diabetes. This means, that without action, the number of people with sight problems in the Dubai is likely to increase dramatically over the next 25 years.

Purpose: The purpose of the eye health needs assessment is:

• To build a picture of current eye health services, i.e. a baseline.
• To gather information in order to plan and change services for the betterment of eye health.

Method: In order to carry out eye health assessment we applied qualitative (focus groups with 20 ophthalmology experts) and quantitative methodology (Analyzing hospital, population health related surveys. Prevalence or incidence estimates based on research from national and international documents. It is intended to help stakeholders discuss the scale of the issue locally.

Key findings:

1. A number of studies have shown that that rate of reported cataracts is around 2% on average. If these estimated prevalence rates (2%) are applied to the population of Dubai(without  adjustment), there may have been 47,716 people with cataract across Dubai in 2015 of which: 33,145 would be males and 14,571 females.
2. It was estimated around 9,144 residents in Dubai aged 40 years or more in 2015 had glaucoma (of which 8,149 were OAG and 995 were ACG).
3. It was estimated there would be approximately 12,128 (95%confidence interval 9,639-15,001) Adults aged 18+ years in 2015 suffering from diabetic retinopathy at some stage.
4. Age-related macular degeneration (AMD) seem to be a rare condition in Dubai and patients and AMD are not often seen at private health care sectors, as it is most common among the older white population.

Abstract:

Purpose: To evaluate for association among socio-economic status (SES), baseline visual acuity, clinical parameters, and treatment outcome in neovascular age-related macular degeneration (nvAMD).

Methods: Retrospective single center cohort study. Patients' residential addresses were extracted from medical records. SES was determined for each patient based on the 2008 Israeli census, and classified into four different groups. Clinical and demographic parameters were extracted from patient charts. The relationship between the SES cluster and clinical parameters was then evaluated.

Results: A weak correlation was found between baseline visual acuity (VA) of the first eye diagnosed with nvAMD and SES (R=-0.13, p=0.049; n=233). No correlation was found between the SES and baseline VA of the second eye (R=-0.05, p=0.95). SES was not associated with the number of anti-VEGF injections of the first (p=0.943) or second eye (p=0.704). No association was found between the SES and the VA outcome of the first or second eye after 1 year of therapy (p=0.421, p=0.900 respectively). Central subfield thickness (CST) at presentation as measured by OCT was associated with SES ( r= -0.31 p= 0.001).

Conclusion:  The lack of association between SES and visual outcome in nvAMD suggests that there are no Social disparities in ophthalmologic care in our study population

Abstract:

ABSTRACT

PURPOSE:  To assess efficacy, safety, and patients satisfaction after unilateral Presby-lasik procedure, compared to multifocal IOl (fine vision), in presbyopic emmetropic patients.

SETTING: Enaim Refractive Medical Centers, Israel.

DESIGN: Retrospective case-series.

METHODS:

26 patients underwent unilateral Phacoemulsification with Femto-laser assisted cataract surgery (FLACS) and refractive lens exchange (RLE), followed by an implantation of a trifocal diffractive intra ocular lens (IOL) (FineVision Micro F). The surgery  was performed on the non-dominant eyes of presbyopic emmetropic patients.

35 patients underwent laser Presby-Lasik procedures in the non-dominant eye, using the Supracore algorithm, Technolas.

 After 6 months of follow-up, the main outcome measures were uncorrected distance visual acuity (UDVA), uncorrected intermediate visual acuity (UIVA), and uncorrected near visual acuity (UNVA). Secondary outcomes included spherical equivalent (SE), refraction, defocus curves, contrast sensitivity, patient questionnaire and presence of visual side effects.

RESULTS: In both groups no sight lost >1 line for corrected distance and near VA.

Overall uncorrected distance and near visual acuity were better in MF IOL group.

Patients satisfaction was higher in the MFIOL, 88%, compared to 63% in the Presby-Lasik group.

CONCLUTIONS: Presbyopic lens exchange with implantation of MFIOL in the non-dominant eye of emmetropic patients is the preferred procedure in age group>48.

Abstract:

Purpose: Evaluation of 10 years results in visual acuity (VA) and central macular thickness (CMT) in patients with neovascular age-related macular degeneration (AMD) in ‘real life’ practice.

Material and methods: This is a retrospective study including   417 patients treated with intravitreal anti-Vegf injections the last 10 years that the specific treatment was introduced as first line treatment for wet AMD.VA and CMT were recorded using SLO-OCT prior to initiation of therapy and at the last follow-up visit of each patient as long as the total number of injections applied.The treatment protocol was PRN with monthly patients’ examination.

Results: The follow-up period was up to 10 years. Visual acuity at the last follow-up was improved in 157 (38%), remained stable in 126(30%) and worsened in 134 (32%). The mean change in CMT was approximately 178±41μ. The total number of injections was 2689. We had 1 case of endophthalmitis responded very well in treatment with no other major side effects or other complications (local or systemic) after the injections.

Conclusion: Intravitreal anti-Vegf injections seem to be, as indicated by ‘real life’ practice data, an effective and safe therapy for the treatment of wet AMD, contributing mostly in preservation of patient’s VA.
