Can corneal edema be missed?

Please read.

How is corneal edema diagnosed? Is a slit lamp enough?

It all started 3 years ago I was 19 years old and realised all my life ''white lights have rainbow faint halos'' (since then i've realised this is a normal variation abberation, I've asked on this site/doctors/ and friends/partner who've said YES they see it too at an angle. But I wanted to make sure...so (read below)

Two years ago at my office the ophthalmologist (glaucoma specialist) as well as a retinal specialist and a optometrist checked my eyes due to a inaccurate reading of high pressure done on a tonopen. (yes I've posted here before).

My pressures were actually 16 on Goldman and over the two year period the glaucoma specialist repeated the test each year, the retinal specialist did once and the optometrist saw me every 4 months out of those two years.

There was no change.

They said the tonopen read my pressures wrong due to 610 cornea thickness. I never asked but it’s come to my attention corneal edema can thicken your cornea - my paranoia has sent me worrying that: my cornea was so thick because the edema over those two years had thickened it that much resulting in a 610 CCT reading, me worrying thinking the edema was due to acute glaucoma.

Any specialist who can answer this for me? Can it be missed? I had the usual slit lamps, OCT, Retina images, dyes and all three doctors searched my eyes multiple times. I know this is an odd post but my worry is through the roof.

My final question, if I had cornea edema due to acute glaucoma for these two plus years now? It would be incredibly obvious correct?

Thankyou, I know I sound like a crazy person. The halos haven't stopped and I accept it as normal now, but I always get paranoid because I'm ''young'' doctors don't check every possibility because ''why would I have it, I'm in my 20's?''. I will remember your reply.

Calm down and relax.  Corneal edema is usually easy to see and that many MDs and ODs would not miss it on multiple exams.  Light height and weight the thickness of the cornea varies from person to person.  And the thickness of the cornea varies somewhat during the day, generally being thickness in the morning after awaking from sleep and thickest at bedtime. This is due to the lids being closed during sleep and less oxygen available.   Your last question YES
