Yoshihiro Yonekawa, Ashkan M Abbey, Ankoor R Shah, Benjamin J Thomas, Antonio Capone Jr Associated Retinal Consultants, Department of Ophthalmology, William Beaumont Hospital, Royal Oak, MI, USA Abstract: Phototoxic maculopathy caused by endoillumination during macular surgery is uncommon. Previously identified risk factors have included intensity of the light source, proximity to the retinal surface, and length of exposure. In the era of indocyanine green (ICG)-assisted internal limiting membrane (ILM) peeling, the use of ICG, and the technique of ILM peeling may both contribute to subsequent phototoxic maculopathy. We present cases of routine chromovitrectomy who developed phototoxic maculopathy in the precise discrete distribution of the ILM rhexes, and discuss potential mechanisms and implications.
