Abstract:
Background Transscleral diode laser cyclophotocoagulation (TDCP) was used to later stage of glaucoma in the past.However,the indications of TDCP are expanding gradually over time and there are more and more reports about its application in different stages and different types of glaucoma.Objective This study was to compare the clinical efficacy of TDCP and trabeculectomy for primary acute angle-closure glaucoma (PAACG) with persistent ocular hypertension.Methods Ninety-five PAACG patients with persistent ocular hypertension were retrospectively analyzed.The patients were divided into TDGP group (62 eyes of 56 cases) and trabeculectomy group (44 eyes of 39 cases) based on the difference of treating fashions.The clinical outcomes were compared between the two groups with the evaluating indexes of visual acuity,intraocular pressure (IOP) before and 1 week,3 months and the end of following-up as well as the number of drug used and the re-treatment.Results The demography was matched between the two groups (all at P＞0.05).The number of eyes with visual improvement was significantly different among the groups (x2 =30.927,P =0.002) in the TDCP group.Compared with before treatment,the number of visual improvement in 1 week after treatment was significantly raised (x2 =16.778,P =0.002).No significant differences were seen in the eye number of visual improvement in various timepoints after treatment (all at P＞0.008).Also,the eye number of visual improvement was significantly different among the different timepoints (x2 =44.345,P＜0.001),and statistically significant change was found between the preoperation and postoperative 1 week (x2 =23.725,P＜0.001).However,there were no significant differences in the eye number of visual improvement in various timepoints after operation each other (all at P＞0.008).The IOP was insignificantly altered among the groups at various timepoints (Fgroup =3.836,P =0.053),but the change was significantly different over time (Ftime =757.078,P＜0.001).The postoperative IOP was significantly higher than that of preoperation in both groups (all at P＜0.001).The proportion of eyes using lowering-IOP drugs was 48.4％ in the TDCP group,and that in the trabeculectomy group was 27.3％,showing a significant difference between them (x2 =4.796,P =0.029).The retherapy was performed in 20 eyes (32.3％) and 2 eyes (4.5％) in the TDCP group and the trabeculectomy group,respectively.Conclusions The short-term lowing-IOP effecacy of TDCP is similar to trabeculectomy,but the longterm lowing-IOP efficacy of TDCP is not good.Compared with the trabeculectomy,TDCP shows more simple operation,less time-consuming during the surgery and milder tissue damage,but the eyes continuing to use anti-glaucomatous drugs or re-therapy are increased.
