Brief Answer:
high blood glucose blurs the vision.

Detailed Answer:
Dear Mr. XXXXXXX hi! if the blood glucose goes high it causes macular oedema and also it forms a foggy layer in front of the cornea so the vision goes blurred. it is very essential to keep good control over blood glucose. besides when we say eye test, we mean you must get your retinal check up. so make sure your fundus /retina is not yet affected by diabetic retinopathy. regards!

So is it temporary phenomenon and our vision gets normal when the glucose level becomes normal.

Brief Answer:
yes that is true.

Detailed Answer:
dear XXXXXXX yes that happens, it is a reversible phenomenon initially . but with repeated high blood glucose, things start becoming permanent like, early cataract in diabetes, vitreous hemorrhage, retinal detachments. so you need good glycemic control, always.

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
