Barriers to a successful board exam were cited.All ophthalmologists had official residency training in Jordanian Hospitals; this includes military, university,governmental and private sector hospitals.RESULTS:Sixty-one questionnaires completed out of69 circulated. Males(75.4%) were more than females.Mean age was 32.5±3.27 y. A total 21(34.4%) responders expressed an overall satisfaction, 38(62.3%) were dissatisfied and 2(3.3%) were equivocal. Respondents reported insufficient exposure to low-vision rehabilitation57(93.4%),or refraction and glasses prescription 34(55.7%).Regarding operative experiences, the mean cataract extraction per-resident was 43 cataracts; the number of phacoemulsification surgery was 2.96 per-resident, 46(75.4%)of responders never did a single phacoemulsificationduring residency. Nine(14.8%) had training in refractive surgery, and 15(24.6%) assisted orbital surgery. Fortyfour(72.1%) never assisted in vitreoretinal surgery.Among The graduates surveyed, 14(23.0%) passed Jordanian licensing board exam at the first attempt, and felt that their residency programs adequately prepared them for the examinations.· CONCLUSION:Around two thirds(62.3%) of ophthalmologists expressed dissatisfaction with residency training at Jordanian programs, further study is required to assess each program separately and evaluate the system of accreditation in Jordanian residency programs.展开更多

Surgeries were performed by four retina surgeons using different viewing systems. Two groups of eyes were compared: microincisional vitrectomy(327 eyes) and conventional(67 eyes) vitrectomy. An iatrogenic tear was defined as the occurrence of one or more peripheral retinal tears during surgery or at any visit in the first 6 wk postoperatively.RESULTS: Mean age was 67±12 y and 55% were female. Iatrogenic tears occurred in 11/394(2.8%) of eyes. The rate of tears was similar among different surgeons and viewing systems(P=0.93 and P=0.76, respectively). Surgical indication, preexisting pseudophakia/aphakia, induction of posterior vitreous detachment(PVD) during surgery, and the use triamcinolone acetonide didn’t significantly affect the rate of tears(P>0.1 for all factors). A higher rate of tears was found in the conventional group compared to the microincisional group(respectively, 7.5%, 1.8%, P=0.02).CONCLUSION: The rate of IRT in vitrectomy is not significantly affected by surgical indication, preexisting PVD or pseudophakia, or use of triamcinolone or different viewing systems but is significantly higher in conventional vitrectomy. Microincisional platforms improve the safety of vitrectomy regardless of the viewing system used.展开更多
