visual acuity

My refractive surgery journey as surgeon and patientMy interest in refractive surgery started in 1976 when my good friend and fellow University of Southern California (USC) ophthalmology resident Rick Villaseñor returned from his course in keratomileusis surgery with Jose Barraquer in Bogota, Columbia.
Outer retinal layer thickness predicts visual acuity in diabetic macular oedemaDiabetes mellitus is a common health problem in developed countries, with diabetic macular oedema (DMO) being a major cause of visual loss. A variety of treatment modalities for DMO are available including laser, steroid and intravitreal anti-vascular endothelial growth factor (anti-VEGF) agents.
Study: Fluocinolone acetonide 0.2 µg/day reduced DR progressionTreatment with fluocinolone acetonide 0.2 µg/day significantly reduced progression to proliferative diabetic retinopathy (PDR) in patients who were part of the FAME trials1,2 and had visual acuity loss due to diabetic macular edema (DME), according to Charles C. Wykoff, MD, PhD.
New prevention and monitoring strategies for neovascular AMDNutritional supplements continue to be a viable prevention strategy for neovascular age-related macular degeneration (AMD), said Emily Chew, MD.
Study finds good visual acuity among French elders
Simple solution for presbyopiaA topical product (PresbiDrops, FEPASAET Group) that provides sustained pupil constriction can safely and effectively increase near and distance UCVA in properly selected presbyopic patients.
IOLs in cataract surgery – do the risks outweigh the benefits in infants?This article presents recent epidemiological findings outlining the association between cataract surgery, potential visual acuity gains, glaucoma and the risk of undergoing additional general anaesthesia in under 2s. The authors of the original study concluded that use of IOLs in cataract surgery in young children should be critically reassessed, particularly in settings/communities where close, long-term follow-up is challenging.

Subretinal fluid protective of vision, CATT study finds
Subretinal fluid protective of vision, CATT study findsSubretinal fluid was associated with better visual acuity, whereas greater thickness of the subretinal tissue complex was associated with worse visual acuity in the second year of the Comparison of Age-related Macular Degeneration Treatment Trials.
