Can Herpes Affect The Eye?
The herpes simplex virus (HSV-1), which also causes cold sores around the lips and mouth, is the source of eye herpes, sometimes referred to as ocular herpes, a potentially dangerous infection of the eye. The most common way to get eye herpes is to touch a cold sore and then touch the eyes with contaminated […]
What is retinoschisis or splitting of the retina?
At the back of the eye is a layer of tissue called the retina. Cone and rod cells make up this structure, which processes light entering the eye through the pupil. The optic nerve carries visual impulses from the retina to the brain. When the retina separates into two layers, a disease known as retinaschisis […]
Punctal Plugs: a treatment for dry eyes
Punctal plugs are microscopic objects inserted into the tear ducts of the eyes (called puncta). Puncta are the tiny apertures in your eyes where tears are released. The blockage, which is about the size of a rice grain, prevents fluid from draining from the eye. This relieves itchy, burning, and red eyes by keeping the […]
What is Sympathetic Ophthalmia?
A rare form of uveitis called sympathetic ophthalmia results in the formation of tiny aberrant cell clusters called granulomas. This condition develops in the unharmed eye following surgery on the other (harmed) eye or a penetrating injury (such as when a pencil, pen, or stick punctures the eye). The unharmed eye’s uveal tract eventually gets […]
Secondary Lens Implantation
SECONDARY LENS IMPLANTATION In order to replace a lens that has been removed due to a cataract, an eye doctor can insert a small, plastic lens implant into your eye. Behind the iris, (the colored part of the eye)the lens is inside the eye. It aids in sharpening images and light for your eye’s iris […]
What kind of surgery is SMILE also known as Small Incision Lenticule extraction
A more recent kind of laser refractive surgery is known as small incision lenticule extraction (SMILE). This type of surgery uses a laser to treat astigmatism and myopia (nearsightedness) (irregularly shaped cornea). Light rays must pass through your cornea and lens in order for you to see clearly. The light is refracted (bent) by the […]
Why does a subcapsular cataract cause decreased eyesight?
Posterior Subcapsular Cataract is a type of cataract, where in, there is opacification in the posterior or back portion of the crystalline lens. This type of cataract can occur alone or in combination with other types of cataracts as well. But the primary occurrence posterior Subcapsular cataract per se is less. Posterior Subcapsular cataract can cause […]
What is Best’s disease and can it be treated?
Best disease, often referred to as vitelliform macular dystrophy, is a retinal condition that results in macular degeneration. The thin tissue that lines the back of the eye is called the retina. Light is converted into electrical signals by rod and cone photoreceptors in the retina, which the brain interprets as vision. Best disease is […]
Why do I see double up close? Is this convergence insufficiency?
The failure to maintain binocular function (keeping the two eyes working together) while workingup close is known as convergence insufficiency. When focused on a word or object at a closedistance, one eye will frequently turn outward (intermittent exotropia).Headaches when reading and diplopia (double vision) are signs of convergence insufficiency. Manypatients will lament their inability to […]
What is Fuch’s endothelial dystrophy?
The endothelium layer of the cornea is affected by the non-inflammatory, sporadic or autosomal dominant Fuchs’ endothelial dystrophy. The cornea thickens and accumulates guttae over many years, resulting in glare, haloes, and decreased visual acuity. In Fuchs’ endothelial dystrophy, the cornea can sustain damage so severe that it may result in corneal blindness. Smoking and […]
