Ryan’s Retina (seventh edition) is edited by Professors SriniVas Sadda, Andrew Schachat, Charles Wilkinson, David Hinton, Peter Wiedemann, Bailey Freund and David Sarraf
Coming in at three volumes, 2,846 pages and 6.8kg on my home scales, the latest edition of Ryan’s Retina maintains its position as the comprehensive text for all things vitreoretinal. It is all-encompassing and falls within the reference category of textbooks rather than light reading. However, there is a certain pleasure in flicking through crisp new pages filled with tiny text that smell like old libraries.
As with previous editions, the seventh is very practically divided into three volumes. Volume one includes retinal imaging diagnostics and basic science/translation to therapy. It has all the usual chapters, including OCT angiography, which many general ophthalmologists and optometrists will find interesting. The B-scan videos in the digital section are great and very useful. There is also a nice section on artificial intelligence (AI) and advanced imaging analysis, written for us non-code-writers. I know Dr Aaron Lee, who co-wrote this chapter, from when we did our fellowship together. He has obviously taught a few people about AI over the last decade, since I was better able to follow this chapter than any AI modelling he spoke about back in the day – a testament to how well written and edited these books are. The whole basic science section is fascinating, but I particularly enjoyed the teaser on microbiome and retinal disease.
