AIM: To do a randomized prospective interventional study for comparing the effects of a single subconjunctival triamcinolone acetonide (SCTA) injection to tapering topical loteprednol in patients undergoing phacoemulsification surgery under topical anesthesia.
METHODS: A total of 400 patients were randomized into 2 groups; Group A (200 patients) received 5 mg SCTA at the end of surgery and topical ketorolac tromethamine (0.5%) with ofloxacin (0.3%) combination for 3wk. Group B (200 patients) received tapering topical loteprednol etabonate (0.5%) along with ofloxacin (0.3%) and ketorolac tromethamine (0.5%) for 3wk. Outcomes evaluated were intraocular pressure (IOP), anterior chamber cells/flare and macular oedema postoperatively at 1, 6 and 12wk.
RESULTS: Baseline parameters were almost similar in both the groups. No statistical difference was seen between the preoperative and postoperative IOP values for Group A (P=0.82) and Group B (P=0.61) and postoperative IOP values in between both groups (P=0.14) at 1wk. Incidence of cells/flare postoperative was statistically not significant (P=0.82) in both groups at all follow up visits. Postoperative macular oedema was not observed at any follow up visit.
CONCLUSION: SCTA appears to be an effective alternative to prolong postoperative topical steroid use. 相似文献

Retinal pigment epithelial detachment, often asymptomatic is a common retinal finding. Multiple serous retinal pigment epithelial detachment especially in a female is very uncommon. We describe a case of multiple retinal pigment epithelial detachments throughout the fundus in a 51-year old female otherwise asymptomatic. Indocyanine green angiography and fundus auto fluorescence showed abnormalities with a normal systemic work-up. This is the first report of an asymptomatic patient correlating angiogram with auto fluorescence in multiple serous retinal pigment epithelial detachments. 相似文献
