The goal of this comprehensive text is to enable ophthalmologists and rheumatologists to differentiate scleral disorders and implement timely treatment plans based on current best practice and available evidence. Extensive updates to text reflect the advances that have occurred in investigation and treatment of scleral disease since the 2nd edition was written between 1998 and 2003. Numerous new and replacement images of the highest quality, particularly (in chapter 5) of Anterior Segment OCT which is being adapted to investigate scleral disease with stunning results. 1000+ new references to relevant key review and research papers.
