This paper communicates the history of a case of subretinal cysticercosis in the left eye of a 73-year-old female patient. The only subjective complaints were slightly blurred vision in the affected eye. Serological findings in the blood (Agar-Gel precipitation; IFAT; ELISA) and the aqueous humor were negative. However, according to the literature false-negative serological findings are not uncommon. A stool examination for worm eggs or tapeworm segments was also negative. The remaining lab findings, including hemogram and immunoelectrophoresis, were also normal. Neurocysticercosis was ruled out by clinical and roentgenologic (CCT) diagnosis. As the patient declined treatment with praziquantel, a modern treatment for tapeworm, photocoagulation of the cysticercus was performed at two sittings, first peripheral demarcation and subsequently central coagulation.

We evaluated a topical formulation of timolol in an anionic heteropolysaccharide gellan gum (Gelrite). Fifty-five white patients with ocular hypertension entered a double-masked, placebo-controlled, four-period, incomplete block crossover study. After washout of any ocular hypotensive medications, the intraocular pressure of both eyes of all patients was measured at 0 (09:00 h), 2, 4, 6, 8, 12, and 24 h (diurnal baseline). Patients were then randomized to receive, at 2-week intervals, one drop of each of four of the six treatments in one eye (0.008% timolol gel, 0.1% timolol gel, placebo gel, 0.008% timolol solution, 0.1% timolol solution, and placebo solution). Fellow eyes received the appropriate placebo. As measured by least-squares means, adjusted for the unmedicated baseline diurnal values, there was a clear dose-response, with the 0.1% treatments being more effective ocular hypotensive agents than the 0.008% treatments, which in turn were more effective than the placebo treatments. Within each concentration at several observation points, the gel formulation elicited a 1-2-mm Hg greater efficacy than the solution. Gel-treated subjects had a greater incidence of blurred vision. We conclude that formulation of timolol with a gel may increase efficacy, and thus duration of action. This may possibly allow use of a lower concentration of timolol or a reduced frequency of instillation. Further evaluation in chronic dosing studies is justified.
