Ophthalmological review needed

Detailed Answer:
Hello and Welcome

I appreciate your concern

zig zagging chevrons is not the usual presentation or history in eye involvement with respect to a serious condition like retinal detachment or vitreous hemorrhage that may lead to sudden vision loss. However, the eye should be examined. Fundoscopy should be done to look for progression of diabetic retinopathy, to rule out proliferative changes or ARMD (Age related macular degeneration). IOP (Intra ocular pressure ) should be checked and visual acuity should also be recorded.

Wishing you best of health

Hi, I had a small vitreous hemorrhage following PVD about 8 months ago (an initial streak followed by thousands of black dots in my vision) from a blood vessle tear on optical nerver. The blood cleared fairly quickly the first two weeks and my corrected vision is 20 20 but has not gotten better since then. When I adjust focus and stair at white background, I can actually see hundreds of tiny circles that I presume are ghost cells. The Dr. was primarily concerned with retinal tears which thankfully I didn't get and has said there's nothing that can be done about a small bit of residual blood in vitreous However, it is very annoying as it swirls around every time I look around. Again my eyesight has returned to 20 20 but I haven't managed to ignore it as I'm involuntarily reminded every minute or so. There are two slightly larger faint spots that are yellowish in sunny conditions. I read that in Asia (Japan, China, Korea) they treat vitreous hemorrhage with iodized lecithin (wo-liteng of jolethin) but there seems no treatment here shy of victrectomy which is not indicated. Do you have any suggestions? Does this ever get better on its own? It's been 8 months. Thank you.

Hi I had a retinal bleed a couple of months ago. I cannot see out of the eye and am waiting for the eye doctor to decide whether an vitrectomy is necessary. I have been invited to a function in Amsterdam next week but wonder if flying will further damage my eye. What is your view
