主 题：learning curve laser peripheral iridectomy primary angle-closure glaucoma
摘 要：AIM:To explore the learning curve for ophthalmologists at the start of laser peripheral iridectomy(LPI)training.METHODS:The learning curve of 4 doctor groups without previous LPI experience was studied.Three main parameters of LPI were reviewed:total energy,argon energy and neodymium-doped yttrium aluminum garnet(Nd:YAG)energy.Procedures were evaluated in cohorts of 20 cases to identify the turning points of the three variables.RESULTS:There was no significant difference in terms of age or eye among the 4 doctor groups.There were stable trends on the learning curve for the Doctor A and C groups regarding total energy and argon energy.In addition,the turning points on the learning curve were determined after the 20th procedure for the Doctor B and D groups regarding total energy and argon energy.Moreover,the Nd:YAG energy was relatively stable since the first procedure.CONCLUSION:It requires approximately 20 procedures for a beginner to reach a turning point on the learning curve regarding LPI.It can serve as a point of reference or guideline for training beginners to perform LPI.
