ABSTRACT
Operating room microscope-induced maculopathy is described in two patients following cataract surgery without intraocular lens implantation. Sequential fundus photographs of evolving retinal lesions are presented. Serial visual field testing disclosed marked recovery of paramacular scotomas over time. The effect of the pseudophakos in producing photochemical lesions is discussed. Proposed mechanisms for recovery of visual scotomas are reviewed.

The ocular hypotensive effect and the safety of levobunolol hydrochloride (0.5% and 1%) were compared with vehicle in this double-masked study of 42 patients with chronic open-angle glaucoma or ocular hypertension. After a washout of ocular hypotensive medication, patients received one of the three test treatments in both eyes twice daily for three months. Both concentrations of levobunolol produced significant reductions in intraocular pressure, while decreases in vehicle-treated patients were minimal. Over the three-month study period, average pressure reductions were approximately 9.0 mm Hg in patients receiving either concentration of levobunolol and 0.5 mm Hg in patients receiving vehicle. Fewer patients were terminated from the study for inadequately controlled intraocular pressure in the levobunolol groups than in the vehicle group. No patients were terminated for drug-related adverse experiences.
