World’s Best Eyesight: 5 Ways Animals Outrank Us
Human eyes are complicated, powerful organs, but there are some animals that beat us to the punch when it comes to vision. While it is almost impossible to conclusively rank which animals have the best eyes, because eyesight encompasses such a broad spectrum of attributes, we can look at how some animals have exceptional vision…

[ad_1] Prevent Blindness has declared Nov. 14-20, 2022, as its third annual “Thyroid Eye Disease Awareness (TED) Week.” TED, sometimes called Graves’ ophthalmopathy or Graves’ eye disease, is an autoimmune disease in which the immune system causes inflammation and swelling and stimulates the production of muscle tissue and fat behind the eye. According to the organization, to help…
Read MoreImpact of treating AMD before visual function is impaired
[ad_1] Japanese investigators led by first authors Risa Aichi, MD, and Norihiro Nagai, MD, reported that before the best-corrected visual acuity (BCVA) decreases and advanced lesions develop in eyes with age-related macular degeneration (AMD) is the optimal time to begin treatment with anti-vascular endothelial growth factor (VEGF) therapy to obtain better outcomes in the real-world clinic. …
Read MoreVision in 3D
[ad_1] So much has to go right as the human visual system develops. One of them is that many thousands of retinal ganglion cells (RGCs) have to relay signals through the eye’s optic nerve via delicate projections, or axons, to precise locations on both sides of the brain that make visual sense of it all,…

[ad_1] Sleep issues, including too much or too little shut eye, daytime sleepiness, and snoring, may be linked to a heightened risk of developing irreversible sight loss (glaucoma), suggests a large UK Biobank study1 published in the open access journal BMJ Open. According to a news release, the findings underscore the need for sleep therapy in…
Read MoreProof-of-concept study advances potential new way to deliver gene therapy
[ad_1] A team of Johns Hopkins Medicine researchers say they have successfully used a cell’s natural process for making proteins to “slide” genetic instructions into a cell and produce critical proteins missing from those cells. According to a Johns Hopkins Medicine news release, if further studies verify their proof-of-concept results, the scientists may have a…
Read MoreMisinformation rampant about unapproved stem cell therapies
[ad_1] Reviewed by Marissa Patel, BA Intravitreal injections of unapproved stem cell therapies have resulted in irreversible blindness. Lack of patient understanding of stem cell treatments have led to these devastating consequences as a result of predatory practitioners. There currently are no FDA-approved stem cell therapies to treat retinal diseases, and the clinical trials evaluating…
Read MoreDigital home monitoring shows predictive value in disease progression for AMD patients
[ad_1] Notal Vision Inc. this week is reporting on the results of its Analysis of Long-term visual Outcomes of ForeseeHome Remote Telemonitoring (ALOFT) study.1 According to a news release, the 10-year retrospective study details the importance of digital remote monitoring for age-related macular degeneration (AMD) patients.1 The second report specifically focuses on early management and…
