In the center of the iris there is an opening called the pupil and behind that another chamber between the iris and the crystalline lens. The lens is a disc shaped living tissue composed of regularly arranged collagen with a capsule. ...Read more

What is the cause of eye floaters?

Aging, mostly: Most of the time floaters appear as a natural consequence of getting older, like seeing the first wrinkle in your forehead. If, however you see floaters that weren't there before, or if you have flashes of light in the periphery of your vision, it's best to get checked out asap by an eye md (ophthalmologist) to rule out retinal tears, which can lead to (vision-threatening) retinal detachments. ...Read more

What is the main cause of eye floaters?

What is the main cause of eye floaters?

Floaters cause: Floaters arise when the vitreous gel inside the eye liquefies naturally with age and sometimes earlier in life due to trauma, inflammation, or even high myopia. The floaters may consist of protein precipitates. Though the vitreous gel inside the eye is clear, it is composed of a complex matrix of collagen proteins that undergo changes. New floaters should be examined under dilation. ...Read more

What is lattice degeneration of the eye?

What is lattice degeneration of the eye?

Retina thinning: There are two types. Lattice dystrophy of the cornea is an uncommon cause of cornea clouding. Lattice degeneration of the retina are areas of thinning in the peripheral retina. Usually they don't cause any problems. They can however be thin enough to tear and cause a retinal detachment. If you have new floaters or flashes of light in your peripheral vision, see an ophthalmologist right away. ...Read more

What causes RNFL thinning in glaucoma. Does controlling eye pressure stop the nerve fiber loss.

What causes RNFL thinning in glaucoma. Does controlling eye pressure stop the nerve fiber loss.

Pressure atrophy: One theory is that pressure too high for the back of the eye to withstand causes constriction of the blood flow with atrophy of the tissue (nerve fiber) supplied by that blood stream. They then atrophy and this is the basis for the thinning. Lowering the pressure below that threshold for damage prevents further blood vessel constriction and allows the remaining nerve fibers to stay healthy. ...Read more

I cannot really understand what happens to the eye in the case of glaucoma. But how's your vision with it?

Not usually: Glaucoma is often silent as you are not able to tell when there is slight damage to the visual field. Furthermore, when eye pressure is an issue, high pressure in the eye, up to about 30, can feel totally normal. No pain, no visual symptoms, or external signs may be present. Only in the late stages does the field constrict to become symptomatic. Prevention is always better so best to get exam. ...Read more

Sometimes the reason for the increased pressure is not known. People over the age of 40, with diabetes, eye injury or eye surgery are at increased risk of glaucoma. Glaucoma is also more common among african americans. ...Read more

Does flying on an airliner changer the eye pressures in glaucoma?

Maybe a little: Altitude can cause changes in eye pressure, but most commercial airplanes are pressurized to less than 8000 feet and private planes generally don't go high enough to make a difference. Whatever the case, the duration of most flights is so short that it shouldn't make a difference. Glaucoma damage takes years to develop and a short spell of elevated pressure is not worrisome! ...Read more

Can reducing the reservoir size for catching the drain from a shunt in the eye for glaucoma help cause back pressure?

Yes: The most common shunts are the ahmed and baerveldt implants. They come in different sizes which are designed to fit larger or smaller eyes and to a lesser extent, regulate the outflow pressures. The pressure is more dependent however on the status of the overlying conjunctival filter. ...Read more
