Most ophthalmology residency programs include rotations in cornea retina, pediatrics, oculoplastics, glaucoma, and neuro-ophthalmology. You will be working with fellowship-trained physicians, observing and sometimes participating in their procedures and seeing how they manage patients in their clinics. The interviewers ask this question to understand what part of the residency program interests you the most and why. They want to see where you will succeed in the program and how they can help you along the way. They also want to know that you have researched the program and what is offered.
