I just released a new study guide for the "basics" of ophthalmology (anatomy, embryology, pharmacology, and principles of pathology) as part of my plan to format and release my notes from residency. It's been a slow process, but depending on the feedback and response I'll work on releasing study guides for other subjects within Ophthalmology!
Follicular conjunctivitis is one of those topics that always seems to pop up on exams. Because questions can be asked about the pathology and differential diagnosis, this is a topic that probably should be very familiar to you.
There are a lot of practice questions on molluscum contagiosum. Although its clinical appearance and histopathology are fairly distinctive, I often confuse this with keratoacanthoma.
Keratoacanthomas are very characteristic-appearing lesions on the skin that also look very distinctive on histopathology. I get these confused on histopathology with molluscum contagiosum, so I think this is an important condition to know.
There are TONS of causes of leukocoria (white pupil). But this can be a very important differential, as it can be the presenting sign of some sight-threatening and life-threatening conditions (most obviously retinoblastoma). Because of its clinical importance, it is essential to be able to not only recognize what it is, but to also have a decent differential diagnosis so that you don’t miss out on any key causes when conducting a history and physical.
