What can you tell me about posner-schlossman syndrome? never heard of it before..

Good question!: Me either! I've only been a doc 30 years, so still learning! This is pretty uncommon but I found a great discussion for both of us. It usually causes episodes of blurred vision with mild pain in one eye, rarely both, that is due to increased eye pressure. These episodes recur. Nobody is sure what causes it. Treatment may be medical or surgical. See the article: https://tinyurl.com/ya9gaqj5
