Follow-up observation of therapeutic effect on external trabeculotomy combined with trabeculectomy for primary congenital glaucoma.

Objective To observe the therapeutic effect of external trabeculotomy combined with trabeculectomy for primary congenitalglaucoma.Methods Sixty-six cases (96 eyes) of primary congenital glaucoma patients treated with exter(n)al trabeculotomy combined with trabeculectomy were observed,the intraocular pressure,cornea diameter,C/D ratio,filter bleb and complication were observed pre- and post-operation,the therapeutic effect were analyzed.Results The mean follow up period wasl 1.76± 8.51months,the successful rate in 1 month,6 months and 12 months after operation was 95.83%,92.06%,87.23% respeectively.The intraocular pressure (IOP) was decreased markedly after operation (P ＜0.01).C/D ratio was decreased markedly (P ＜0.01).There was no statistical difference in cornea diameter between pre- and post-operation (P =0.495).The cornea diameter enlarged in those failed in operations.The complications were various degrees of hypema and shallow anterior chamber.Conclusions External trabeculotomy combined with trabeculectomy is a safe and effective way to treat primary congenital glaucoma.
