What causes scaring in the eye if you have macular degeneration?

Retinal breakdown. Scarring the in the maculae can occur in both the wet and dry forms of macular degeneration. Usually, it is problematic in the wet form when there is leakage of serum or blood from new blood vessels that cause inflammation and retinal scarring - here the prognosis is guarded. In advanced forms of dry macular degeneration there can be scarring as well.
Macular degeneration. In macular degeneration, the photoreceptors that gather light become damaged in the eye, either through accumulation of drusen deposits, or through blood (in wet amd). Damaged photoreceptors die off, leaving a scar in the macula, and poorer vision. Wear sunglasses and eat green leafy vegetables to keep your eyes healthy.

Can Macular Degeneration be considered "wet" in absence of blood or water in the eye? Grandmother dx as early wet (occult) but no blood or water seen.

"Wet" in the description of Macular Degeneration (WMD) refers to EXUDATE, (a combination of fluid plus white blood cells) and is the more "advanced" type. BOTH lead to vision loss but there are optical ways of helping people with this disorder! Hope this is helpful! Dr Z. Read more...

Does smoking affect retina or the vitreous (back part) of the eye in anyway other than in macular degeneration?

Yes. Yes, there is some evidence that smoking can be associated with macular degeneration changes for sure. Read more...
There is little. Proof that smoking alone affects the retina or vitreous, other than making macular degeneration worse or causing optic nerve problems (rare). Smoking does promote cataract progression, and is generally very unhealthy and should be avoided! Read more...
You are correct. Smoking is always a bad thing and is best avoided. The only known problem related to smoking in the back of the eye is the macular area, but we always advise smokers to stop immediately because so many body functions are affected and it is a leading cause of death. Read more...
