For the first time approximately 5 months ago, I awoke in the morning with a red and what appeared to be swollen caruncle in my right eye. This persisted for a few days, while slowly returning to normal. It has recurred multiple times since then, it seems like I will go weeks without an issue, then for no detectable reason, the redness returns one morning upon waking. It has always been the right eye only, the left is never involved. It is worst immediately upon waking and in the most recent case, fades within 1-2 hours, but still appears to be there at a much reduced level for a period of time after. I have not made any changes to my hygiene practices and am not applying any products (make up, etc) to my face. I have no known allergies and it is always the right caruncle, never the left. The first time it happened, I had redness on the white of my eye between the caruncle and the iris, but that has not returned since or has been minor on the subsequent carcuncle events. I had an ophthalmologist examine my eyes in 3 months ago with no findings. The caruncle redness was not present at that time and is hard to catch since it can resolve quickly. Any ideas on what could be the cause of this?
