In terms of resources to use, the Royal College of Ophthalmologists has an official document to outline which online/paper tools in addition to examination courses are available (see link below). Commonly used/essential resources include the below:
1) RCOphth Guidelines
2) NICE guidelines
3) Oxford handbook of Ophthalmology, Denniston & Murray – great quick overview of everything but very few images hence slightly boring to read. Good for on-the-go reading/quick access to read up on things while at work.
4) Clinical Ophthalmology: A Systematic Approach, Kanski & Bowling – great to cover gaps in reading/go into more depth (please remember that the exam largely is focussed on identifying what is important and discussing your management as you would plan in clinic, as opposed to as a specialist in that field therefore very in depth reading is arguably not necessary
5) Viva and OSCE Exams in Ophthalmology: A Revision Study Guide, Timothy H.M. Fung, Winfried M.K. Amoaku
