Retinal degeneration causes blindness by destroying the photoreceptor cells in the retina. Some forms of degenerative blindness leave intact other cell populations, however. What if those populations could be granted some of the same mechanisms used by photoreceptor cells to pass signals to the optic nerve? Researchers here demonstrate a gene therapy that does just this, a most interesting feat of engineering. It is still a poor alternative to prevention of the condition, or restoration of lost photoreceptor cells, but it is no less impressive for it. This is truly an age of biotechnology. Scientists inserted a ge...

AbstractDiabetic retinopathy is one of the most major causes of blindness and disability in diabetic patients and imposes very high cost on Health Care System. Studies conducted in the country showed different and inconsistent prevalence of the disease. The study aims to determine the overall prevalence of retinopathy in patients with type 2 diabetes in Iran through a systematic review and meta-analysis. The present study was conducted via meta-analysis method during March, 2000 to October, 2018. The articles related to the subject under study were obtained from Magiran, SID, Medline (PubMed), Science Direct, Scopus and Go...

CONCLUSIONS: These data suggest that the majority of LCA/EORD in Costa Rica is due to four founder mutations in RPE65 which have been maintained in this genetically isolated population. This finding is of great clinical significance due to the availability of gene therapy recently approved in the US and European Union for patients with biallelic RPE65 defects.

Retinal degenerative diseases such as macular degeneration, glaucoma, and diabetic retinopathy constitute the leading cause of blindness in the industrialized world. There is a continuous demand in investigative ophthalmic research for the development of new treatment modalities for retinal therapy. Unfortunately, efforts to identify novel neuroprotective and neuroregenerative agents have often been hindered by an experimental model gap that exists between high-throughput methods via dissociated cells and preclinical animal models. Even though dissociated cell culture is rapid and high-throughput, it is limited in its abil...

In conclusion, this meta-analysis represented a significant correlation between TLR4 polymorphisms and both types of glaucoma suggesting that TLR4 might be involved in the pathogenesis of glaucoma and may be applied as a genetic marker for disease screening.

This study explores data from an awareness and screening campaign conducted in Lebanon. Diabetic patients from multiple regions were referred by their endocrinologists to undergo NMFP using the Optomed SmartScope® handheld fundus camera. Photographs were interpreted by a remote observer, and recommendations were given accordingly. The prevalence of DR was calculated, and statistical analyses were performed on the clinical characteristics, fundus findings and number of referrals to ophthalmologists. RESULTS: The campaign lasted 11 months, during which 2205 patients were examined in 37 screening locations. Out of the...

Authors: Harissi-Dagher M, Slim E Abstract Penetrating keratoplasty is the most commonly performed tissue transplant in the world. However, its success depends on the health of the ocular surface and the intact immune privilege of the eye. In the absence of these two conditions, corneal transplants have an increased failure rate and result in corneal blindness. For more than two hundred years, researchers have been trying to find the best design of the artificial cornea in order to address these cases of severe corneal blindness. Despite previous difficulties, interest in the field has recently been revived, and co...

In his new book, Deep Medicine, the cardiologist argues that artificial intelligence can bring humanity back to medicine. You tweet several times a day about the latest medical studies. Do you really read all of those articles? Every one of the 18,000 tweets come from me. People think I have an army of people to help me–no. I’m an information junkie. Ever since I was a kid I’ve been an incessant reader. I apportion time every day–a couple of hours in the morning and the evening. What is the biggest problem you see in medicine today? What’s happened is an erosion of the relationship, due to the...
