Dermatochalasis causing apparent bitemporal hemianopsia.

We describe a previously unreported cause of apparent bitemporal hemianopsia. Three patients with bilateral dermatochalasis underwent Humphrey visual field (HVF) testing in anticipation of corrective blepharoplasty. Unexpectedly, the HVF showed bitemporal hemianopsia in each case, prompting magnetic resonance imaging of the brain in one case. The scan was negative. The HVF tests were repeated with the upper eyelids taped in elevation, and were normal. We conclude that the bitemporal hemianopic defects in our patients resulted from the testing strategy employed by the HVF analyzer software to measure the visual field. Reasons for these artifactual results are discussed. Clinicians should be aware of this uncommon cause of bitemporal hemianopic visual field defects.

Systemic non-Hodgkin's lymphoma with optic nerve infiltration in a patient with AIDS.

PURPOSE: To report the clinicopathologic features of a patient with AIDS and clinically regressed systemic non-Hodgkin's lymphoma who subsequently developed lymphomatous infiltration of the optic nerve and occlusion of the central retinal vein in both eyes. METHODS: The eyes of this patient were examined ophthalmologically and by fluorescein angiography. The eyes, brain, and body were obtained after death and studied by light microscopy. RESULTS: Ophthalmic examination and fluorescein angiography revealed optic nerve swelling and central retinal vein occlusion first in the left eye and shortly thereafter in the right eye. Postmortem histopathologic examination showed dense infiltration of both optic nerves by lymphoma as well as necrotizing vasculitis involving the retinal vessels near the left optic nerve head. Examination of the brain revealed lymphomatous involvement in the paraventricular region with associated necrosis and inflammation. No bone marrow recurrence or other residual systemic lymphoma was present. CONCLUSION: This case demonstrates that infiltrative optic neuropathy may occur as the sole ocular manifestation of disease recurrence in a patient with systemic non-Hodgkin's lymphoma otherwise thought to be in clinical remission.

Surgical management of glaucoma in pseudophakic patients.

Pseudophakic patients that require surgical management of glaucoma have many of the same options as phakic patients. Considerations when performing incisional glaucoma surgery (trabeculectomy with adjunctive antimetabolites and glaucoma drainage device implantation) and laser glaucoma surgery (laser trabeculoplasty and laser cyclophotocoagulation) in pseudophakic patients are reviewed here. The decision to operate and the choice of surgical procedure must be individualized for each patient.
