Anti-VEGF Injections

Ophthalmologists Perform Proportion: Intravitreal Anti-VEGF Injections

The frequency of Anti-VEGF Injections (vascular endothelial growth factor); has grown exponentially with the introduction of bevacizumab, ranibizumab, and most recently aflibercept. The cost associated with these medications has garnered significant national attention; warranting a granular analysis of their use. However, three % of ophthalmologists perform 17% to 31% of all anti-vascular endothelial growth factor (VEGF)…

Diabetic retinopathy Influence Cataract Surgery

Every ophthalmologist is going to have a diabetic patient walk into the office; who is going to have a visually significant cataract surgery. Diabetic retinopathy is the leading cause of vision loss among patients with diabetes; and a primary cause of blindness among working-age adults. The purpose of the study was to evaluate how diabetic…

Gene Replacement Surgery Restores Vision In Patients

Being one of the first medical institutions nationally to complete a revolutionary gene replacement surgery; to restore vision in patients with retinal degeneration, surgeons of The Vision Center at Children’s Hospital Los Angeles (CHLA); have successfully completed the procedure by adding 13 patients. The outcomes of two of those patients, San Diego residents Monroe Le;…

Glaucoma Can Be Diagnosed By Machine

Untreated glaucoma is a major cause of sight loss. There are several forms and they are all essentially cause by damage; to the optic nerve due to increased pressure within the eye. A collaboration between scientists in Algeria and Belgium; has led to a new “intelligent system” for glaucoma detection that promises to help diagnose;…

Smartphone-Based Telemedical DR Screening Improve Ophthalmic Care

Diabetic retinopathy (DR) is the most common cause of blindness in working-age adults worldwide. Millions of people in developing and emerging countries are at risk of impaired; sight due to a lack of early diagnosis and treatment. About one in ten people in India is diabetic. Around one in three suffers from a so-called diabetic…

Previous Herpes Zoster-Related Ocular Disease: Cataract Surgery

Eyes with a history of herpes zoster-related keratitis or uveitis were at high risk for herpes zoster disease; recurrence after cataract surgery, according to a study. A retrospective case series included 57 eyes of 57 patients with herpes zoster-related keratitis; or uveitis who underwent cataract surgery in the ipsilateral eye. The cohort was evaluated for…

Why Visual Cortex Involved In Language Processing In Blind Individuals?

People who are blind use part of their visual cortex for language and semantic processing. The visual cortex is the paradigm case of a “modality-specific” brain region; being devote exclusively to visual perceptual processes in healthy and blind individuals.  Why should it shift its function in the blind toward higher cognition; in particular language and…

Young Diabetes Patients Undergo Needless Retinopathy Examinations

A retrospective analysis of clinical trial data indicates that regular eye examinations; may not always be necessary for people younger than 18 years of age with type 1 diabetes; despite current recommendations to the contrary.“If moderate NPDR [non-proliferative diabetic retinopathy] or more severe retinopathy stage is found on the initial screen;” the researchers suggest that…

Glaucoma

Glaucoma Is Linked With Blood Pressure, Diurnal IOP, Disc Hemorrhage

Researchers have linked normal tension glaucoma (NTG) progression and vascular insufficiency in the lower IOP setting. This study aim to assess the other factors that may be involved in the progression of NTG. NTG is my least favorite type of glaucoma. The fluctuation of diastolic blood pressure, diurnal IOP and the presence of a disc…

Protein In The Eye Can Protect Against Diabetic Retinopathy

A study performed by researchers at Joslin Diabetes Center have show that a protein found; in the eye can protect against diabetic retinopathy and potentially treat diabetic eye disease. At high enough levels, Retinol Binding Protein 3 (or RBP3) prevents the development of diabetic retinopathy. If introduce early enough in the development of the disease;…

Regenerating Human Retinal Ganglion Cells Used In Glaucoma Treatment

The human central nervous system  have the capacity to regenerate after injury or illness is limit; and the resulting functional impairments carry a vast social and personal burden. In glaucoma, degeneration of retinal ganglion cells (RGCs) the axons of which form the optic nerve; which is connecting the retina to the brain leads to permanent…
