Agni Malmin and colleagues published a study in the May 2023 edition of the journal Ophthalmology that was quite eye opening (if you’ll pardon the pun).

Recently, I’ve noticed a major uptick in the number of journals in the field of ophthalmology. When there are so many titles to read and digest, it certainly can feel overwhelming. Of course, not everything is related to my quotidian practice, but some of this information is really interesting anyway. I suppose the best thing…
