Purpose To evaluate 24-h efficacy of travoprost/timolol fixed combination (TTFC) vs latanoprost/timolol fixed combination (LTFC) in exfoliative glaucoma (XFG). Design A prospective, single-masked, crossover, active-controlled, randomized 24-h comparison. Methods After up to a 6-week medicine-free period, XFG patients were randomized to either TTFC or LTFC for 3 months, dosed each evening, and then changed to the opposite treatment for another 3 months. At the end of the washout, and both treatment periods, a 24-h intraocular pressure (IOP) curve was measured.

SIGNIFICANCE Central serous chorioretinopathy (CSCR) is still a therapeutic challenge with no criterion standard treatment. However, anatomic changes at the level of the retinal pigment epithelium could prove of predictive value in the course of the disease for selective treatment in cases of increased risk of chronicity. PURPOSE This pilot study analyzes the efficacy for treating acute CSCR with combined systemic acetazolamide 250 mg twice a day and nepafenac 0.1% eye drops three times a day in comparison with an untreated control group. It also evaluates the presence a pigment epithelial detachment (PED) as a risk factor for chronic CSCR. METHODS Nineteen consecutive patients (group 1) with new or new onset of recurrent CSCR were treated with oral acetazolamide and nepafenac eye drops for at least 2 months. A control group of 14 patients (group 2) with new or new onset of recurrent CSCR were untreated while under regular observation for 4 months. Primary end points were central macular thickness and best-corrected visual acuity after 4 months. Secondary end points were complete regression of subretinal fluid at 3 months and association of PED at baseline with recurrent or chronic CSCR imaged by optical coherence tomography. RESULTS Group 1 showed significantly faster resolution of subretinal fluid with a mean central macular thickness at 4 months of 271 ± 85 μm compared with 322 ± 79 μm for group 2 (P < .05), but with no functional benefit with a best-corrected visual acuity at 4 months of 0.8 ± 0.2 for group 1 compared with 0.9 ± 0.1 for the control group (P < .05). Patients with a small flat PED were at a higher risk of developing chronic CSCR compared with patients with a dome-shaped or no PED (P < .05). CONCLUSIONS Central serous chorioretinopathy remains a therapeutic challenge. This pilot study shows faster resolution of subretinal fluid with treatment but without functional benefit compared with observation. The presence of small, flat PED was associated with development of chronic CSCR.

This village had a high frequency of glaucoma, with 12% of the participants aged 10 to 95 years having the disease. In this cohort, the Thr377Met MYOC mutation was significantly associated with both high intraocular pressures and high vertical cup-to-disc ratios. No association was found with central corneal thickness.

This pilot study demonstrates for the first time a possible significant reduction in retinal arterial caliber under aflibercept treatment for diabetic macular oedema. Further studies are needed to verify whether this response to intravitreal anti-VEGF treatment also signifies an improvement in retinal vascular homeostasis.
