Recent advances in the instrumentation and surgical techniques for posterior segment surgery permit better anatomic and functional outcomes. Nevertheless, these procedures may be associated with complications involving the anterior segment, including postoperative inflammation and hypotony. One must differentiate infectious from noninfectious inflammation to initiate appropriate therapy promptly. Hypotony is a frustrating problem because it is difficult to reverse. The exclusion of eyes with other known causes of hypotony is important before establishing the putative mechanism of tractional ciliary body detachment caused by epiciliary proliferative tissue.
