Researchers Create 3-Dimensional, Retina-Like Structure

University of California-Irvine researchers have created this retina-like structure out of human embryonic stem cells in hopes that one day it may serve as transplant material for macular degeneration and other diseases of the retina.

What is a Stye?

A stye, or hordeolum, is a small bump that can appear on the outside or inside of eyelid developing from an eyelash follicle or an eyelid oil gland that becomes clogged from excess oil, debris or bacteria. Styes can be brought about by increased stress, but can also be a complication of blepharitis (inflammation of eyelid). The treatment includes warm compresses, gentle massage of affected area and antibiotic ointment or eye drops.

Long Term Corticosteroid Use May Lead to Cataracts Glaucoma

Long Term Corticosteroid Use May Lead to Cataracts Glaucoma Corticosteroids are used with countless people by suppressing the immune response and inflammation. They are the cornerstone of treatment for ailments like rheumatoid arthritis, asthma, ulcerative colitis, and many other diseases. With long-term use they have serious side effects such as weight gain, hypertension, osteoporosis, diabetes, thinning […]

Researchers develop photochromic lenses

In Singapore researchers have developed UV-responsive, or lenses that darken when exposed to ultraviolet light, protecting the eyes against the sun’s damaging rays. The lenses contain a novel polymer laced with an intricate network of nano-sized tunnels filled with dyes. The investigators hope to have these photochromic contact lenses commercially available within a year.

Gecko’s Multifocal Vision

Nocturnal helmet geckos are among few living creatures on Earth that are able to perceive and distinguish colors at night. Their eyes feature a series of concentric zones of varying refractive powers comprised of large cones (cells that perceive color) up to 350 times more sensitive than human cones.

Color Vision Deficient Patients

Patients with color vision deficiency must wear sunglasses according to a study published in the April issue of Optometry and Vision Science. Those sunglasses should have ultraviolet protection and polarization to reduce the damaging rays of the sun. Grey lenses were also recommended since grey filters the visible light spectrum equally.

What’s Race Got to Do With It?

While each patient is an individual, racial differences exist for certain eye conditions and knowing these differences affects diagnosis and treatment. For example, some forms of glaucoma (primary open angle) is up to 4.3 times more prevalent in blacks compared to whites. In addition, the prevalence of type 2 diabetes is twice as high in […]

Seven out of 10 children…

Study indicates seven out of 10 children, young adults may be deficient in vitamin D. Low vitamin D levels have been associated with high blood pressure and high blood sugar levels and lowering of the HDL which is the “good cholesterol” which put together put a child at future risk of cardiovascular disease. In a study […]
