Hello doctor,

I am a 39-year-old female. I am diabetic and taking Glycomet, Empagliflozin, and Vildagliptin. My HbA1c level is about 7.3. I have been taking a calcium channel blocker (25 mg) for three years now to control tachycardia. I do not take any other medications.

I have never had vision problems until about six months ago. I wear glasses, but my power is minimal (-0.75 to -1) in both eyes, and I have cylindrical and spherical power. Six to eight months back, I started experiencing floaters, and I had a thorough eye check-up of my retina, fundus, etc., to ensure that there was no problem. The test results were normal. My intraocular pressure has always been high (23 to 24 mm Hg), which has been the case for the last several years, but my optic nerve has always been fine. I have not been prescribed any medication to treat my eye pressure.

However, for the last couple of months, I have been experiencing some vision issues. It is more pronounced these days. For example, looking at a white tube light even for a few seconds, I start seeing yellow lines all over, which fade away in, say, 30 seconds. I see any patterns on the floor or tv. When I look at a wall nearby, I can see the after image briefly, and it fades. I once saw full horizontal grids in my vision for close to two minutes after seeing my phone for a long time. It has never happened before.

My other concern is when I look at a plain blank wall, and I see floaters, I see jumping or moving lights (it is not light, but a feeling of things moving, it is very hard to explain). I had a retinal examination done again, and the doctor told me that there was no issue. I am very nervous and anxious! Any advice will be greatly appreciated.



Welcome to

I read your history, and it is a very common concern I see in my day-to-day practice, most probably due to muscae volitantes.

Seeing floaters, after images of objects, etc., is very common, and these are usually self-resolving, like in your case as well. I would have recommended a fundus or retinal examination to alleviate your concern, but I see you have already undergone those examinations, and I am happy to know they are all normal. Sudden flashes of light like you see in your case can be quite concerning for me because it usually means something serious like what we call vitreoretinal traction leading to a retinal detachment. But again, since you have got your fundus checked, I am not worried.

Your spectacle power is low, and hence you are at low risk of retinal issues. Usually, people with high spectacle power, like -6 and more, are at higher risk. Even I see these after images and floaters you see. I suggest you do not stress out a lot. Most are normal phenomena.

Just be vigilant and watch out for sudden flashes of light in your vision, especially when you move your eyes vigorously, sudden black spot in your vision which does not go away, and sudden blurring of vision. Otherwise, I feel you are doing very well.


Hi doctor,

Thank you so much for your reassurance. My flickering or jumping kind of sensation when I look at surfaces is also nothing to be worried about, right? That is the one causing the most nervousness for me. This is something new, and my husband or kids dont see or experience what I am experiencing.



Welcome back to

You need not worry at all. I would suggest consulting a neurologist if you feel it is very bothersome. If it gets too much, get yourself checked for a possible migraine and a neurological evaluation. Otherwise, I think you should relax and enjoy yourself.
