Today I went to the hospital to visit the opthalmologist. The good news: as expected, what happened the other day was just a case of optical migraine, which needs no treatment and I shouldn't worry about. Thanks to everyone who mailed me or commented in the blog giving advice or wishing me luck!
The doctor examined my retina, and found nothing wrong with them that would cause “lights” or total blindness. He did find what he described as “the start of retinal folding”, which might be congenite, but I should keep an eye on in case it becomes a real problem. Apparently I should be vigilant to objects appearing with deformed shapes, etc.
So I came back earlier that expected to office, but I really can't do anything here due to the pupil dilation. Everything is blurry, light is extremely annoying, and I'm writing this using a ridiculously big terminal font.
The “get decent sleep” plan continues, and I've been sleeping the expected amount of hours since last Tuesday.
