What is a posterior subcapsular cataract and ischemia of the optic nerve?

What is a posterior subcapsular cataract and ischemia of the optic nerve?

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.

Cataracts (Definition)

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

What is a posterior subcapsular cataract and ischemia of the optic nerve?

2 different things: Posterior subcapsular cataract is a change in the lens transparency from deposits and alteration of the back capsule of the lens. Ischemia of the optic nerve is deficiency of the blood supply to the main nerve of sight with loss of vision.

Can you tell me about being diagnosed with posterior subcapsular cataracts?

Can you tell me about being diagnosed with posterior subcapsular cataracts?

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.

What is the technical definition of posterior polar cataract?

What is the technical definition of posterior polar cataract?

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.

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?

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.

Why do post-cataract surgery retinal detachments occur? Is there some retinal pulling involved from posterior vitreous detachment (pvd)?

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.

For someone who had posterior vitreous detachment completed prior to cataract surgery, what is the risk of post-cataract surgery retinal detachment?

For someone who had posterior vitreous detachment completed prior to cataract surgery, what is the risk of post-cataract surgery retinal detachment?

Very small: As vitreous traction is the main cause for retinal detachment following cataract surgery, if the vitreous is already separated, there would be no traction and thus the chance of a detachment would be very small.

How to know when do cataracts cause blindness?

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.

What would cause severe starbursts after YAG procedure following cataract surgery?

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?

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.
