In unequal alternating monocular exposure (unequal AME), each eye receives normal patterned visual input but on alternate days and for unequal periods. It has been shown previously that this imbalance in stimulation produces a deficit in the nasal visual field of the less experienced eye (LEE). The effect of subsequent binocular exposure on these visual deficits has now been examined. No eviden...

The effects of early monocular form deprivation on the developing mammalian visual system, and the anatomical and physiological consequences of early monocular enucleation, suggest that the remaining eye of human subjects who had the other eye removed early during development might be capable of supernormal performance. To test this inference, the achromatic contrast sensitivity of the remainin...

Background: A scleral buckling procedure repairs retinal detachments by indenting the sclera under the retinal breaks. One of the complications is diplopia, which typically subsides once the muscle heals. Persistent diplopia lasting longer than three to six months is reported in 0.5% 25% of patients. Case Reports: The cases presented demonstrate the use of optometric vision therapy and/or prism...

AIM To present the results of endonasal endoscopic orbital decompression in patients with Graves' ophthalmopathy. METHODS Endonasal endoscopic orbital decompression was performed in 32 orbits of 21 patients with Graves' ophthalmopathy. In 17 patients the surgery was performed because of active ophthalmopathy non-responsive to conservative treatment, and in 4 patients for esthetic reasons. Pre...

Introduction: Cranial traction leading to 6th nerve palsy is the main cause of developing diplopia following spinal surgery. Very few cases of abducens nerve palsy as a complication of surgery without cranial traction have been described. We review a series of four patients who developed diplopia following spinal surgery only one of which had cranial pins or apparent traction on the abducens ne...

AIMS To assess the results of visual axis alignment following one stage adjustable suture surgery to correct vertical diplopia. METHOD Eight patients with a mean age of 44.9 years (range 16-80 years) complaining of vertical diplopia underwent rectus muscle recession under local anaesthesia with intraoperative adjustment of sutures. Diplopia was secondary to superior oblique paresis in four pa...

Diplopia is an infrequent complication after blepharoplasty. Most of the cases are in its vertical form due to trauma of the extraocular muscles. In this article, we present a case of horizontal diplopia following cosmetic upper blepharoplasty; we review the literature on this unexpected complication and offer some recommendations to avoid it.
