if you have 5 electives, you should see if you can get into 2 months of ophtho. Your program director might okay a second month of ophtho if it's in a subspecialty like ocular pathology or neuro-ophthalmology. Rheumatology is a great idea. A neurology rotation would probably be helpful too, but I'm not sure if it's worth the extra work when you could just do an easy one.
