Causes Of Posterior Subcapsular Cataract
2 different things: There are many types of cataract. Posterior subcapsular cataract refers to cloudiness on the back part of the lens just under the capsule. This may be caused by injury, steroids, elevated blood sugar and aging. Ischemia of the optic nerve means that there is or was an episode of poor blood flow to the nerve which may result in vision loss.See 1 more doctor answer
Occurs whent here is a clouding (or change in protein composition) of the normally clear lens (which is located behind the pupil and iris) inside the eye. Cataracts are most commonly due to aging, but can be congenital (born with it), due to trauma or uveitis (eye inflammation). Can be worsened by long-term topical steroid ...Read more
Back of lens: This is a change in the lens transparency from the growth of material under the back, central portion of the lens. It is typical as a complication of systemic diseases and medications like high dose steroids. It can occur naturally and usually is more common in slightly younger patients than ordinary senile cataracts.
Cataract from birth: When the lens is being formed during pregnancy, sometimes the back portion of the lens forms abnormally and can leave an opacified area. Many times this is not visually significant, but it can be. Any opacification of part of the lens is considered a cataract. Since this occurs from birth it is called a congenital cataract.See 1 more doctor answer
Displaced lens from cataract surgery. I can see the lens (black circle floating in lower eyeball. Is it anterior or posterior?
Posterior: Displaced lenses are almost always posteriorGet a more detailed answer ›
I had posterior uveitis then cataract surgery last year. Recently I was diagnosed with Grave's Disease. Is all of this somehow related?
It can be but low: Uveitis can be associated with Thyroid disease but it is ususlly a very low percent around 2%. It is been found mainly in poorly controlled hyper thyroidism. You could be check to see if you have any other autoimmune phenomena that might explain your case. Your physician should be able to help you with this.
If posterior vitreous detachment happen in yung high myopic like me without retinal tear, is der a chance of future retinal tear due 2 cataract/glucoma?
Higher: The risk is probably 10 x greater than a patient without these characteristics. Risk ia about 1/1000 unless you have a family history. Having glaucoma and a cataract do not increase this risk. Having cataract surgery does increase the risk of retinal tears. You should talk your eye md.See 1 more doctor answer
Why do post-cataract surgery retinal detachments occur? Is there some retinal pulling involved from posterior vitreous detachment (pvd)?
Destabilization: The natural lens and its supports stabilize the front of the eye and vitreous. Removal of the thick natural lens and substitution with a thin artificial lens, increases the chance for the vitreous to move in ways that can destabilize the attachments of the vitreous over the retina. If there are weak places, this can increase the chance of detachment, even in the best of cataract surgeries.See 1 more doctor answer
For someone who had posterior vitreous detachment completed prior to cataract surgery, what is the risk of post-cataract surgery retinal detachment?
When advanced: Cataracts cause a progressive lowering of the vision but do not cause permanent blindness since they can be removed even when very advanced. This assumes that everything else in the eye is normal except for the cataract. Cataracts are the leading cause of blindness on earth since surgery is unavailable in many poorer countries.See 1 more doctor answer
Juvenile cataracts: Congenital cataract: during pregnancy, mom has infection (ie measles/rubella (the most common cause), rubeola, chicken pox, cytomegalovirus, herpes simplex, herpes zoster, poliomyelitis, influenza, Epstein-Barr virus, syphilis, toxoplasmosis. Juvenile: include, prior trauma, infection, inflammation, JRA. Macular degener: gene mutation-> Stargardt's disease, Best disease, and juvenile retinoschisis
No: Not in my opinion. Most cataracts are age related. Some also due to long term steroid use or medical conditions.
Not dangerous: Class 1 led products are defined as being "safe under all conditions of normal use", and the vast majority of led's fall into this category. However, it is also recommended not stare at the led or shine the led into your eyes or those of another person. Class 1 led products should also not be used by children without adult supervision. Led's should have no risk of causing cataract.
See your eyedoc: Seeing better out of an eye with a multifocal lens following YAG might do it. Other causes might be a new PVD, severe pitting of lens, corneal edema from intraocular pressure spike, and other causes. You need to consult your ophthalmologist to ease your mind! Best wishes.
Can a laser for a simple retinal tear cause or increase your risk of getting a cataract from heat or some other factor? How likely is this?
Not likely: The typical light spectrum of lasers used to treat retinal tears will pass through the lens with practically no absorption. There is no risk of cataracts from this although you are at an age when cataracts start to become more common. But blame your age and not your laser treatment.See 1 more doctor answer
