Is the main cause of vision loss in older people glaucoma, diabetes, or macular degeneration?

Depends on age. There is a different spectrum of vision loss in these conditions depending upon age. Diabetes can alter the vision and will affect younger patients but diabetics tend to die from their disease and fail to reach old age. Glaucoma is common throughout older age but mostly is treatable. Macular degeneration is more common in the very elderly who are healthy enough to reach older ages.

How soon would macular degeneration that has started to turn WET (occult) lead to vision loss in 93 year old? Days, weeks, months? Urgent help needed

Depends. Unfortunately there is no good answer. I can affect your vision tomorrow with a big bleed or in a few more months. There is no way to predict it. Sorry. Read more...
Variable. Wet AMD is usually successfully treated with injections that clear up the vessels and the fluid leakage. This is not a cure but when successful it then turns into the slow progressing dry form. At age 93, with no vision loss yet, it is likely that good vision will be preserved for many years.

At what age are you at risk for vision loss from macular degeneration?

Older age. Macular degeneration is mostly a condition of old age. There are a few inherited forms that can start in the 40's and 50's but most do not appear until the 70's and beyond. The risk is modest but increases with age. Some forms can be modified with treatment so see your retinal specialist if you suspect a problem. Read more...
50 years. Generally beginning at age 50 at the earliest. There is a strong inherited component; exposure to tobacco also increases risk. Read more...

If an elderly hospital pt who has untreatable macular degeneration reports a further loss of vision then, normally, would it be a waste of time for the hospital to even look into the matter?

Any loss of vision. should be investigated as the cost of low vision societally is huge. However, in many socialized medicine countries, the older the patient, the less public health dollars are available for care to treat 'untreatable' conditions. There is wet and dry AMD. So, in either case, it does warrant further ophthalmological care to prevent against blindness. Read more...

Can laser photocoagulation be used to treat macular degeneration? I was recently diagnosed with the "dry" form of macular degeneration. Is having laser photocoagulation a treatment option available to me, and would this prevent further vision loss? .

There . There are two main classifications of macular degeneration: dry and wet. The dry form is generally less debilitating, slower progressing and more common. The wet form generally has a much more profound effect on vision, is faster in its progression, fortunately less common and can vary greatly in treatment response. Treatment for the wet form can range from laser, a procedure called photodynamic therapy, injections into the eye (a relatively new form of treatment) and surgery. Now, treatment for the dry form is more controversial. It can range from simple observation, controlling one's lipid profile and a specific vitamin therapy. A type of laser procedure called ttt (transpupillary thermotherapy) has been used but with little success and traditional laser photocoagulation is not the procedure of choice for dry macular degeneration. Hope this helps. Read more...
There . There is no firm evidence that laser will prevent progression of vision loss with dry macular degeneration. There have been studies that showed that the drusen (yellow spots in the macula), when treated with laser, decreased in number. It is not known for sure what that means for the future of vision in these patients. Read more...
Standard . Standard of therapy for dry form of degeneration is observation. For the wet form of this condition there are several treatment options, one of which is laser photcoagulation. Read more...
Laser no help. Laser for dry macular degeneration has been studied well. Laser to the macula of dry amd patients makes drusen go away, so it looks better on exam. The laser does not change whether or not there is vision loss. Vitamin supplementation is the only proven preventive therapy, and reduces the risk of vision loss by about 25%. The vitamin formula now recommended is called areds 2 formula. Read more...
