PURPOSE To investigate the ability of a portable pupillometer, capable of 20-second binocular recordings of the swinging flashlight test (SFT), to detect relative afferent pupillary defects (rAPDs). METHODS Pupillary response curves were recorded from both eyes in healthy volunteers (n = 22) with and without simulated rAPDs (using neutral density filters (NDFs)) and in abnormal patients (n = ...

OBJECTIVES/HYPOTHESIS Maxillofacial trauma frequently involves the bony orbit that surrounds the ocular globe. Concomitant globe injury is a concern whenever orbit trauma occurs and in severe cases can occasionally result in vision loss. The mechanism of injury, physical exam findings, and radiographic imaging can provide useful information concerning the severity of the injury and concerns for...

PURPOSE Pituitary adenomas are the most common cause of an optic chiasmal syndrome, and treatment of these lesions is considerably different from the treatment of most of the other lesions in this region. Although the diagnosis of a pituitary adenoma is usually inferred from the results of neuroimaging, lesions other than pituitary adenomas can have an appearance that suggests an adenoma. The o...

Dear Editor, Orbital compartment syndrome (OCS) is one of the few emergencies in ophthalmology which if not handled urgently , can lead to catastrophic results. Multiple etiologies such as retro-bulbar hemorrhage, trauma, orbital mass and sometimes orbital cellulitis/abscess have been implicated. We report an uncommon association of subhyaloid hemorrhage secondary to retinal venous stasis in a ...

PURPOSE To report the development of optic neuropathy after botulinum A toxin injection for restrictive myopathy from thyroid-related orbitopathy (TRO). METHODS We retrospectively reviewed the records of three patients with TRO who underwent botulinum A toxin injection for restrictive myopathy and subsequently developed optic neuropathy. Development of optic neuropathy was measured by visual ...
