In a country like the United Arab Emirates (UAE), with its glittering skyline and bustling streets, having poor eyesight can cause you to miss out on so much. Imagine not being able to fully appreciate the awe-inspiring architecture of the Burj Khalifa or the sparkling waters of the Palm Jumeirah. Picture struggling to navigate the vibrant souks and bustling malls, unable to soak in the rich culture and intricate details of the treasures on display. Poor eyesight might even rob you of the simple joys of watching the sun set over the desert horizon or enjoying dolphin encounters in the best marine-themed parks in the country. Having a clear vision opens up a world of endless possibilities in a city teeming with life and wonder. This guide will help ensure you never miss a moment of Emirati magic with seven simple tips for maintaining healthy eyesight.

1. Watch Your Diet

Good eyesight begins with what you eat. Omega-3 fatty acids, lutein, zinc, vitamin C, and vitamin E are some of the nutrients you need to maintain your eye health.
  • Incorporate foods like carrots, sweet potatoes, and citrus fruits for vitamins A and C.
  • Enjoy almonds, spinach, and cold-water fish like salmon for vitamin E, lutein, and omega-3 fatty acids.
  • Don’t forget zinc-rich foods like beans and lean meats.
A balanced diet supports healthy eyes and helps reduce your risk of obesity and type 2 diabetes, major contributors to vision loss. (more…)

MedicalResearch.com Interview with: Daniel Maloney, Ph.D Farrar Lab Smurfit Institute of Genetics Trinity College Dublin MedicalResearch.com: What is the background for this study? Would you briefly describe the condition of Dominant optic atrophy? Response: Dominant Optic Atrophy (DOA) is a progressive blinding disorder that affects roughly 1:10,000 to 1:30,000 people. It is primarily caused by mutations in the OPA1 gene, which plays a pivotal role in the maintenance of the mitochondrial network. There is currently no way to prevent or cure DOA. We sought to build upon previous work to test if OPA1 could be delivered as a potential gene therapy intervention.  (more…)

MedicalResearch.com Interview with: Matthew Campbell, PhD Smurfit Institute of Genetics Trinity College Dublin Dublin MedicalResearch.com: What is the background for this study? What are the main findings? Response: Age related macular degeneration (AMD) is the most common form of central retinal blindness in the world. However the underlying causes and initiating factors for disease progression are still not clear. It is classically a disease of the outer retina, where cells called retinal pigment epithelial (RPE) cells degenerate. However, our findings suggest that some of the early initiating events that promote AMD progression are actually coming from the inner retina and more specifically the microvasculature of the inner retina. We discovered that a gene called claudin-5 appears to be regulated by a circadian rhythm that in turn can regulate what gets into and out of the retina on a daily basis. Dysregulating the levels of this component made the inner retinal blood vessels marginally leaky and promoted a pathology that was AMD-like in animal models.  We also showed that the blood vessels of the retina appear to be highly dynamic in human subjects and can appear leakier at different times of the day, likely a mechanism that allows for clearance and replenishment of material into and out of the retina.  It is this process we believe breaks down in early AMD.  (more…)

MedicalResearch.com Interview with: Michael Silverstein, M.D., M.P.H. Professor of Pediatrics Director of the Division of General Academic Pediatrics Vice chair of research for the Department of Pediatrics Boston University School of Medicine MedicalResearch.com: What is the background for this study? What are the main findings? Response: Gonococcal ophthalmia neonatorum, or GON, is a severe infection of the eye that can occur in babies born to women who have gonorrhea. If left untreated, GON can cause serious problems, including blindness, that can appear as soon as 24 hours after delivery. Fortunately, there are effective treatments available that can prevent GON in newborns. The U.S. Preventive Services Task Force reviewed the most current research on the benefits and harms of ocular prophylaxis—which is applying antibiotic ointment to the babies’ eyes at birth—to prevent GON. We found that, if applied within 24 hours after birth, the ointment is very effective at preventing gonococcal ophthalmia neonatorum and the problems it causes. Therefore, we are recommending that clinicians provide this preventive service for all newborns.  (more…)

MedicalResearch.com Interview with: Wen-Tao Deng, Ph.D. Department of Ophthalmology, College of Medicine| University of Florida, Gainesville, FL MedicalResearch.com: What is the background for this study? What are the main findings? Response: Blue cone monochromay (BCM) is a devastating vision disorder characterized by loss function of both L- and M-cones due to mutations in the L- and M-opin gene cluster on the X chromosome. BCM patients display severely reduced visual acuity, loss of color-vision, myopia, nystagmus, and minimally detectable cone-mediated electroretinogram. In our studies, we showed that an M-opsin knockout mouse model resembles human BCM, and expression of either human M- or L-opsin individually or combined through adeno-associated viral vector promotes regrowth of cone outer segments and rescues M-cone function in the treated M-opsin dorsal retin (more…)

MedicalResearch.com Interview with: Steven Levy MD CEO, MD Stem Cells Study Director, Stem Cell Treatment Studies MedicalResearch.com: What is the background for this study? Response: MD Stem Cells is the sponsor of the Stem Cell Ophthalmology Treatment Study II (SCOTS 2) the largest stem cell study currently addressing retinal and optic nerve disease (NCT 03011541). SCOTS uses autologous bone marrow derived stem cells (BMSC) typically provided to the eyes by combining retrobulbar, subtenons and intravenous injections. Many retinal and optic nerve diseases are eligible including Retinitis Pigmentosa (RP), Age Related Macular Degeneration (AMD), Stargardts, Ushers, Glaucoma, Ischemic Optic Neuropathy, Optic Atrophy and others. Statistically significant improvements have been documented in key diseases and positive responses have been noted across most conditions treated. Mechanisms of action may include differentiation of the CD34 cells into neurons, secretion of neurotrophic factors, transfer of mitochondria and release of mRNA. These may benefit existing stressed cells as well as provide replacement of damaged or absent cells. (more…)

MedicalResearch.com Interview with: Dr. Stephen Rose PhD Chief Research Officer Foundation Fighting Blindness (FFB) Dr. Rose comments on the announcement of the FDA approval of voretigene neparvovec (LUXTURNA™) gene therapy for inherited blindness due to mutations in the RPE65 gene. What is the background for this announcement? What were the main findings from the study? Response: While it has been 30 years since the RPE65 gene was identified as causing Leber’s Congenital Amaurosis, this shows that it is possible to have an effective gene therapy for an inherited disease. As the first gene therapy for the eye or for an inherited disease, LUXTURNA is a historic milestone in the search for cures for all inherited retinal diseases (IRDs). As a one-time gene therapy, LUXTURNA will not only be life-changing for patients with vision loss due to mutations in the RPE65 gene, it also provides critical momentum for gene therapies - for the eye and other diseases - now in the clinic.  (more…)

MedicalResearch.com Interview with: dr-anneke-i-den-hollanderAnneke I. den Hollander, PhD Department of Ophthalmology and Department of Human Genetics Donders Institute for Brain, Cognition, and Behaviour Radboud University Medical Center Nijmegen, the Netherland MedicalResearch.com: What is the background for this study? What are the main findings? Response: Age-related macular degeneration is caused by a combination of genetic and environmental factors. Rare genetic variants in the complement system have been described in AMD, but their effect remains largely unexplored. In this study we aimed to determine the effect of rare genetic variants in the complement system on complement levels and activity in serum. MedicalResearch.com: What are the main findings? Response: Carriers of CFI variants showed decreased FI levels, carriers of C9 Pro167Ser had increased C9 levels, while C3 and FH levels were not altered. Carriers of CFH and CFI variants had a reduced ability to degrade C3b, which for CFI was linked to reduced serum FI levels. (more…)

MedicalResearch.com Interview with: Dr. Andrew Bastawrous, Ophthalmologist Rolex Awards for Enterprise United Kingdom Dr. Bastawrous’ smartphone-based portable eye examination system, Peek Vision, allows patients in low resource setting, to be screened for vision problems and eye diseases, enabling accurate diagnosis and treatment. MedicalResearch.com: What is the background for Peek Vision? What are the main findings of your work with this system? Response: Mama Paul has been blind for almost 20 years, most of her time is spent within the safety of her tiny home. It is basic, but in her mind’s eye she can still picture where the door is, her son - Paul, lives next door and is always willing to help. Losing sight is the sense most people fear losing most. I am severely visually impaired, I am also fortunate to have perfect vision when wearing corrective glasses or contact lenses and privileged to be in the profession of ophthalmology where centuries of research and practice have brought us to a time when so much of blindness is now curable or preventable. There is no feeling like it: when the eye patch comes off someone who hasn’t seen for years, the sheer wonder as they take in their surroundings and their anticipation to see faces that have become voices and places that have become memories. Back in 2011, as I pondered and planned for the challenges that lay ahead of us in Kenya, I had the continual thought that there must be an easier way to reach people, a way that is less expensive, less resource hungry and therefore could be used on a much wider scale. In Kenya, and much of Africa, more people have access to a mobile phone than they do clean running water. It had to be possible to harness this connectivity. (more…)

Paul Miller PhD student The University of Queensland Australia MedicalResearch.com Interview with: Paul Miller PhD student The University of Queensland Australia Medical Research: What is the background for this study? What are the main findings? Response: All humans have a blind spot in each eye where the optic nerve, which sends signals to the brain, passes through the retina, the light sensitive layer in each eye. Where this happens you cannot detect light, so people are blind to images that project to this location. Behaviorally, people tend to report blindness for an area that is larger than physiology dictates. We found this curious, and thought it might be driven by people reporting blindness for regions that border the blind spot, where sensitivity is degraded, but not absent. If so, we thought that this could be improved by training. When we tested this theory, we found it was true - we were able to reduce the extent of functional blindness by about 10%. (more…)

Professor James Bainbridge, MA, PhD, FRCOphthProfessor of Retinal Studies, UCL Institute of Ophthalmology NIHR Research Professor, NIHR Biomedical Research Centre at Moorfields Eye Hospital NHS Foundation Trust and UCL Institute of OphthalmologyMedicalResearch.com Interview with: Professor James Bainbridge, MA, PhD, FRCOphth Professor of Retinal Studies, UCL Institute of Ophthalmology NIHR Research Professor, NIHR Biomedical Research Centre at Moorfields Eye Hospital NHS Foundation Trust and UCL Institute of OphthalmologyConsultant Ophthalmologist, Moorfields Eye Hospital NHS Foundation Trust Medical Research: What is the background for this study? What are the main findings? Prof. Bainbridge : Leber Congenital Amaurosis (LCA) is one of the most common causes of inherited, untreatable blindness in children. There are at least 14 different types of Leber Congenital Amaurosis of which LCA Type 2 (LCA2), caused by defects in the gene RPE65, affects around one in 100,000 people worldwide. Evidence from animal studies support that LCA2 may be amenable to treatment with RPE65 gene replacement therapy. The main findings of this phase I/II clinical trial confirm our preliminary findings (published in NEJM, 2008) that gene therapy can improve night vision. Improvements peak within the first 12 months after treatment but then decline during the three-year follow-up period which is consistent with the published results and interim findings from other studies of RPE65 gene therapy.

Chiu-Fang Chou DrPH Division of Diabetes Translation National Center for Chronic Disease Prevention and Health Promotion CDC, 4770 Buford Hwy, NE (K-10) Atlanta GA 30341-3727MedicalResearch.com Interview with: Chiu-Fang Chou DrPH Division of Diabetes Translation National Center for Chronic Disease Prevention and Health Promotion CDC, 4770 Buford Hwy, NE (K-10) Atlanta GA 30341-3727 MedicalResearch.com: What are the main findings of the study? A: We estimated nearly 9 million people aged 40 years and older are visually impaired using the National Health and Nutrition Examination Survey. Three out of every four people aged 40 years and older with VI have uncorrected refractive error that could be easily corrected with simple glasses or contact lenses. The ocular disease most associated with visual impairment in our study sample was age-related macular degeneration. Finally, increasing age and low educational attainment were significant predictors of visual impairment. (more…)

Michael Belkin, MA, MD Professor of Ophthalmology Director, Ophthalmic Technologies Laboratory Goldschleger Eye Research Institute Tel Aviv University Sheba Medical Center Tel Hashomer 52621 IsraelMedicalResearch.com Interview with: Michael Belkin, MA, MD Professor of Ophthalmology Director, Ophthalmic Technologies Laboratory Goldschleger Eye Research Institute Tel Aviv University Sheba Medical Center Tel Hashomer 52621 Israel MedicalResearch.com: What are the main findings of the study? Dr. Belkin: Modern ophthalmic treatment, when freely available is able to reduce the incidence of blindness, and presumably visual impairment considerably. In Israel the rate of new cases of blindness per 100.000 people [age adjusted] was reduced between 1999 and 2010 from 33.8 to 14.8, i.e., by over 56%. The reduction was in all major causes of blindness, Age-related Macular Degeneration (AMD), Glaucoma, Diabetic Retinopathy and Cataract. In the non-treatable retinal dystrophies such as retinitis pigmentosa, there was no significant changes over this period. (more…)
