A faden operation was performed in 187 eyes that were studied by indirect binocular ophthalmoscopy at regular intervals after the surgical procedure. Of these eyes, 29 (15.5%) showed ocular fundus abnormalities, with 28 cases of chorioretinal scars at the level of the muscle scleral anchorage and one case of Herpburn-Amalric triangular syndrome of choroidal ischemia. No case of retinal tears was found in this series. Fundus changes are by far the most frequent complication of the faden operation, and to our knowledge, this has not been previously described. The findings of the present study suggest (1) the necessity of routine ophthalmoscopic controls in the postoperative stage regarding those eyes in which the faden operation has been performed, and (2) that the faden operation on the lateral rectus muscle is seriously contraindicated because of the high risk of irreversible macular damage consecutive to these chorioretinal lesions.
