Question about vision loss!

Summary

Should someone with high myopia and family retinal detachment history worry about eye problems like dry eye or NAION when starting reta?

The original poster noticed dry eye after their first 1 mg dose and is concerned due to research on eye issues plus personal risk factors. Others note NAION as the main reported concern with these drugs and suggest dry eye is usually dehydration-related rather than a direct retinal threat. Advice centers on hydration, electrolytes, eye drops, and getting a baseline dilated exam with a retina specialist even if a recent check was normal. Most expect symptoms to resolve with fluid intake and view serious issues as low to moderate risk in this situation.

What this discussion establishesStill open

Whether reta specifically raises retinal detachment risk beyond the user's existing myopia-related vulnerability.

Nothing here is advice.

Started with a 1 mg dose last Tuesday and noticed dry eye shortly after. Further reading turned up studies suggesting these medications can affect the eyes. Not diabetic but there is family history on my father's side. High myopia already makes retinal detachment more likely, and my dad experienced it because of his poor vision. Is reta something to be worried about?

The eye problem that concerns me most is NAION. I may not have seen every report on vision effects from these drugs, but NAION is the main one that stood out. I have had a detached retina and so did my father; it was handled with a scleral buckle and not a major issue.

Overall I see low to moderate concern for serious eye problems from reta given your details. Dry eye is probably just benign and tied to dehydration. Still, do not ignore it. With high myopia and family history you are already higher risk for retinal issues. If it were me I would schedule a dilated exam soon, preferably with a retina specialist, mention the dry eye and reta use, and have them look for lattice degeneration or other myopia-related weaknesses. Stay well hydrated and monitor how it feels. Quick improvement would be reassuring.

Had a full exam just a month ago and everything looked fine. The only note was higher risk of detachment from the high myopia.

My strong guess is the dry eye or any mild blur is more often from dehydration caused by reduced fluid intake from GI effects or from temporary lens shifts due to metabolic changes, not a direct retinal problem. Expect it to settle with better hydration. That is only my guess though. Others might have different input. Searching terms like dry eye, vision changes, myopia, retinal, or detachment should turn up similar experiences from people with high myopia where symptoms eased with hydration or artificial tears. Maybe check other spots like reddit for more targeted discussion. Good luck and feel free to update.

Agreed that dry eyes are dehydration in the great majority of cases. Try electrolytes and lubricating drops to see if it improves. Still see a doctor again if it seems necessary.

Were you already on a GLP1 before starting reta? Just wondering, as I have nothing else to add. When I began sema my vision sometimes went wobbly or oddly unfocused, but it was brief and seems to be a known side effect.

No I have not. I think sema in particular has more eye issues reported compared with the others.
