Background: Cystoid macular edema is a common clinical finding following intraocular surgery. Certain medications have been associated with an increased incidence of cystoid macular edema. This article describes the clinical findings in two eyes of two patients in whom cystoid macular edema developed directly following treatment with the anti-glaucoma medication latanoprost, and assesses the possible causal relationship., Case Reports: Clinical correlative and angiographic studies of two patients in a referral practice are presented. The main outcome measurement was visual acuity and fundus examination on discontinuation of latanoprost., Results: Cystoid macular edema developed in two pseudophakic patients after the use of latanoprost., Conclusion: Latanoprost should be used with caution in pseudophakic and aphakic patients--especially those with retinal vascular fragility, any inflammatory uveal disease, or other factors that may predispose to the breakdown of the blood-retinal barrier.

Seven automobiles were washed and waxed at four car washes. Photographic determinations were made of the glare produced by the wet or dry waxed windshield in a headlight beam. When wet, the waxed windshields scattered three times more light than in the normal human eye. The wet wax scattering was 24.8 times higher than when dry. No wax residues should be permitted on windshields and the National Highway Traffic Safety Administration should issue a mandatory windshield cleaning requirement after waxing.
