Initially, a 5 cc retrobulbar injection of 2% Xylocaine was done.  Then, a lid speculum was inserted and the conjunctiva was incised 4 mm posterior to the limbus.  A 2-0 silk traction suture was placed around the insertion of the lateral rectus muscle and, with gentle traction, the temporal one-half of the globe was exposed.  The plaque was positioned on the scleral surface immediately behind the macula and secured with two sutures of 5-0 Dacron.  The placement was confirmed with indirect ophthalmoscopy.  Next, the eye was irrigated with Neosporin and the conjunctiva was closed with 6-0 plain catgut.  The intraocular pressure was found to be within normal limits.  An eye patch was applied and the patient was sent to the Recovery Room in good condition.
