Abstract:
Objective:To evaluate the efficacy and safety of limited pars plana vitrectomy(LPPV), pressure-controlled phacoemulsification(PCP), intraocular lens implantation(IOL), and posterior capsulotomy (PC) in treatment of nanophthalmic glaucoma eyes which intraocular pressure(IOP) were still out of control after peripheral iridectomy.Methods:All 24 patients(29 eyes) with nanophthalmic glaucoma whose IOP failed to be reduced after peripheral iridectomy and needed LPPV plus PCP plus IOL plus PC were recruited from July 2017 to April 2021. The age of these patients was(44.6±11.0) years old. Preoperative and postoperative IOP, best corrected visual acuity(BCVA), anterior chamber depth(ACD) and number of glaucoma medications were recorded by chart review and compared by using paired t-test or Wilcoxon signed rank-sum test. P<0.05 was considered as statistical significant. IOP could be controlled in normal range(≥5 mmHg and≤21 mmHg), without both of disease progression and serious complications were regarded as the success criteria of the operation. Surgical success rate was evaluated. Surgery-associated complications were recorded. Results:The average follow-up time was(11.52±12.44) months. After the microsurgery, IOP decreased from(33.12±9.25) mmHg to(14.23±3.44) mmHg( P<0.01); The ACD increased from(1.23±0.46) mm to(2.86±0.62) mm, and the median number of glaucoma medications dropped from 3(3,4) to 3(0,3) at final follow-up visit( P<0.05). There were no significant differences in BCVA( P=0.196) and the degrees of angle closure(AC) ( P=0.478) before and after operation. The total surgical success rate was 86.2%(25/29) at the final follow-up visit. Two eyes suffered from local choroidal detachment which recovered within 2 weeks with medical treatment. Conclusion:LPPV plus PCP plus IOL plus PC is a safe and effective novel surgical procedure in the treatment of nanophthalmic glaucoma patients with uncontrolled IOP after peripheral iridectomy. It could significantly decrease IOP, increase the depth of ACD, reduce the number of glaucoma medications and maintain BCVA. It can be considered as a first choice for the surgical management for patients with a such condition.
