As the retinal pigment epithelium (RPE) of the eye gets older, a number of changes happen in your eye: 1. Loss of melanin 2. More lipofuscin in the RPE layer. Lipofuscin are chemical by-products. 3. More drusen, which are yellow, lipid deposits, between the RPE and the choroid (the layer of blood vessels that supplyContinue reading “Preserving Vision with Age”

A soft multifocal contact lens wearer came in for an annual eye examination. Best corrected visual acuity was 20/20 right eye and 20/50 left eye. Dilated fundus examination revealed an epiretinal membrane in the left eye, which was the cause of decreased vision. Epiretinal membrane results when a a thin fibrous tissue forms on theContinue reading “When Your Vision Is Not Clear….”

Chronic dry eye can be caused by inflammation which affects your eyes’ ability to produce tears. Dry eyes cause discomfort, burning, stinging, eye fatigue, sensitivity to light, eye redness, a sensation of something in your eye, and tearing. Only a thorough physical examination can determine the severity of your dry eye, with appropriate treatment. IfContinue reading “Severe Dry Eye”
Drusen are yellow, lipid deposits in the retina. These usually appear in age related macular degeneration, but sometimes they appear in persons must younger. In the case below, a young male in his 30’s with 20/25 visual acuity in both eyes.

by Dr. Yvonne Alomia Optic nerve drusen are abnormal globular collections of protein and calcium salts which accumulate in the optic nerve and usually become visible after the first decade of life. They occur in both eyes more often than just one eye. Retinal photos and ocular coherence tomography, shown here, are very helpful inContinue reading “Optic Disc Drusen”
In 1950, Phillips Thygeson published case reports on a superficial punctate keratitis (inflammation of the cornea) that he described as a condition involving corneal opacities. Today, this condition, now known as Thygeson superficial punctate keratitis (TSPK), is a chronic one, lasting years to decades. It typically comes and goes, causing discomfort, but then improvesContinue reading “Thygeson’s Inflammation of the Cornea”
