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!
Embryologic Development Of The Eye
Truth be told, there is not very much detail that needs to be learned about embryology; after all, we've already learned embryology in medical school. At the same time, there are some key embryology concepts that are very helpful to understanding ocular disease, and may also show up on test questions. There usually seems to be at least one question that addresses embryology, and there are tons of practice questions that test your knowledge of embryology.
