My eye doctor told me that papilledema (i don't have) often accompanies visual symptoms (vision loss, photopsia) caused by brain tumors. Why is this?
Eye = external CNS: The eye is the only externalized part of the central nervous system. Papilledema, swelling of the optic disc, is due to elevated intracranial pressure (icp) at the level of the lamina cribrosa, where the intraocular pressure (iop), if lower than the icp, permits swelling of the nerve fiber layer. Brain tumors or idiopathic intracranial hypertension (iih) can cause papilledema and visual loss. ...Read moreSee 5 more doctor answers

Cataract?: A prophylactic laser peripheral iridotomy is performed when a person has narrow and occludable iridocorneal angles, which can cause acute angle closure glaucoma and profound to total vision loss. The hole in the iris is a "pressure release valve" to prevent angle closure, but the inflammation or treatment following the procedure can increase the pace of cataract formation. Check your glasses too. ...Read more
Which form of macular degeneration is more serious? L was recently diagnosed with the dry form of macular degeneration. Is this form more or less likely to cause vision loss or other problems than the wet form?
This : This is actually an interesting question. The answer is that both forms cause vision loss. Dry mac degen causes a slow progression, so this is better in some ways. On the other hand, there is no treatment for the dry form, so the end result may be very severe loss of vision. Wet md causes a more sudden loss of vision due to bleeding or swelling. There is treatment, in the form of injected medications, that can halt the progression, and in 50% of patients may actually cause some improvement! ...Read moreSee 3 more doctor answers
