Risk factors include old age, trauma, use of Tamoxifen and female gender. There are 4 stages of macular hole. The most useful test to detect macular […]

What is the retina? Imagine that your eye is like a camera, and the retina is the photographic film. The retina is a fine sheet of nerve tissue lining the inside of the eye (see diagram). Rays of light enter the eye and are focused onto the retina by the lens. The retina produces a […]

The surgery involves removing the opaque cataract and replacing it with a plastic intra-ocular lens. Many middle aged patients ask if there is something they can do to prevent or delay cataract formation. In my opinion, the following things […]
In a healthy eye, the photoreceptors (rods and cones) in the retina convert light into tiny electrochemical impulses that are sent through the optic nerveand into the brain, where they are decoded into images. If the photoreceptors no longer function correctly—due to conditions such as retinitis pigmentosa—the first step in this process is disrupted, and the visual system cannot [...]

Little lid spasms are common, but they can sometimes be a sign of trouble. A slight tremor of the eyelid—the type that shows up without warning but scrams just as suddenly—is usually no cause for concern, explains Dr. Wayne Cornblath, a professor of ophthalmology at the University of Michigan’s Kellogg Eye Center. “I think everybody has these […]
