Doctor insights on:
Sometimes: The focus of the eye is greatly affected by the lens - diseases such as cataract and presbyopia can dramatically affect the focus. Sometimes corneal scarring may induce astigmatism and keratoconous may cause irregular astigmatism requiring contact lenses to treat. ...Read moreSee 2 more doctor answers
No: Anything causing a deposit anywhere on the cornea is termed an opacity - most due to a specific injury such as a foreign body or ulcer of the cornea after healing. Corneal dystrophy is more generalized throughout the cornea affecting one or another layer, some inherited and others like the condition fuch's, which is acquired. See your corneal specialist ophthalmologist to sort this out. ...Read more
I have intermittant pain in my eye that feels similiar to a scratched cornea-no visual disturbance. What could this be a symptom of?
See an eye doctor: It could be dry eye, a scratched cornea, a foriegn body in the eye, or possibly an infection. If you've had a scratched cornea in that same eye before, sometimes the area of old injury can intermittantly open back up to give a similar foreign body sensation. ...Read moreSee 2 more doctor answers
Fuchs: Fuchs is a disease of the inner layer of the cornea. In some pts, this layer fails over time and the cornea can become swollen. When the cornea is swollen, the patient can experience vision loss. Additionally, some patient's with Fuchs' get a plaque or membrane in their central corneal causing vision decline. In these instances, surgery such as DSEK (partial corneal transplantation) is helpful ...Read moreSee 2 more doctor answers
Two answers: Professor Fuchs described many different eye findings. The two conditions that bear his name are Fuchs dystrophy of the cornea, an age-related deterioration of the endothelial cells lining the inside of the cornea and leading to cloudy vision in some. The other is Fuchs cyclitis, an inflammatory condition of the eye leading to cataract and glaucoma. ...Read moreSee 3 more doctor answers
Retinitis Pigmentosa: The only one i can think of right off is retinitis pigmentosa, and inherited degenerative disorder of the retina. There are probably other retinal disorders that can cause blindness, but most serious conditions you might think of such as cataract and glaucoma are treatable. ...Read more
Corneal opacificatio: When the transparency of the corneal can no longer be maintained or treated, and the cornea is not amendable to other non full-thickness procedures, like DSAEK, then a careful decision for full thickness corneal transplantation is considered. Prognosis for corneal transplantation procedures highly depends on the initial cause(s) of the corneal failure. ...Read more
My father has recently been diagnosed with cornea disease, and we are in the early stages of researching possible ways to fix this problem. We've been told about a fairly new procedure called DSAEK. What is DSAEK, and how does it differ from others?
Iritis: Lupus, rheumatoid arthritis, sarcoidosis, tuberculosis, lyme disease, syphilis, hla-b27 disease, trauma, herpes, inflammatory bowel disease, psoriasis, toxoplasmosis, and many other issues may cause iritis. In many cases, no cause is found. You should be evaluated by an eye doctor. ...Read moreSee 1 more doctor answer
Arcus senilis: The arcus senilis is a donut ring of lipid deposition at the edge of the cornea. This is an arc, and not a spot. You can get donut like spots as a healing response to previous trauma. I know of no pathology that causes such spots so this is probably a benign event for you. ...Read more
Depends: Scarring is rare from contact lens over wear which usually creates symptomatic surface changes for which the lens will be removed by most. The most common scar producing effect is corneal ulcer; a bacterial culture under the lens. Most of these are peripheral and after treatment the scar causes little change. But if the ulcer is central, the scar can cause great visual changes. ...Read moreSee 1 more doctor answer
How do antioxidants prevent chronic diseases such as cancer, heart disease, and macular degeneration?
Maybe: For macular degeneration - free radicals appear to play a significant role. There is currently a prevention arm of the areds which is looking at supplements in preventing the progression of macular degeneration. It's often better to eat a good diet, exercise and reduce other risk factors than take supplements. Oh yes, please don't smoke! ...Read moreSee 1 more doctor answer
foreign body: Most commonly, a foreign body, like a speck of dirt, a metal shard, etc will get into your eye and cause a corneal abrasion. These can be painful and need to be treated, especially if over the pupil, so scarring is less likely to occur (which if occurs over the pupil could cause visual problems). ...Read more
How are infectious diseases, degenerative diseases and diseases caused by the environment different?
Disease definitions: Disease is 'being out of balance' -- 'dis' which means 'negative' and 'ease'.. Infectious diseases generally relate to illnesses caused by germs. Degenerative diseases are more 'chronic' in nature, as things wear out- whether from too much inflammation, old age or some kind of damage. Environmental diseases arise from exposures - like mold in the work place. There are docs that specialize in these ...Read more
As part of glaucoma diagnosis i was told that I have low normal central corneal thickness. Does this mean below average thickness of cornea?
Progressive macular pucker 20/30 vision, distortion & glaucoma. Visual fIeld good,nerve damage 30-45%.Would vitrectomy cause glaucoma to progress?
Possible: Vitrectomy and glaucoma may have an association. It is suspected that glaucoma occurs more often in patients who have had vitrectomy and subsequent cataract surgery. An ongoing clinical trial is aimed to answer this question with more clarity.
