Evaluación de resultado del tratamiento quirúrgico en el glaucoma avanzado

Abstract

IntroductionThere is uncertainty regarding the outcomes of glaucoma surgery for patients with advanced glaucoma, because it may be associated with the «wipe out» phenomenon.The aim of this study was to evaluate the outcome of surgical treatment in advanced glaucoma. MethodsThis retrospective study included 67eyes of 49 patients with end-stage glaucoma in which glaucoma surgery was carried out. The clinical records prior to and after surgery were reviewed. Follow up period was 14.4months. ResultsThe mean age was 50.2years and the sex ratio was 0.75. All the patients had a tubular visual field with persistence of a central island. The mean value of the mean deviation on automated perimetry was 18.94dB±4.7. The mean intraocular pressure (IOP) before surgery was 27.16mmHg±8.9.Postoperatively the overall success rate was 93% (IOP <18mmHg with stable visual acuity). The mean IOP was 14.25mmHg±4.12 (P<.001). There was no significant change in the mean visual acuity. The mean value of the mean deviation was 18.83±4.69 (P=.07). No occurrence of wipe-out phenomenon was noted. The early postoperative complications were hypotony, hyphema and ocular hypertension and they were transient without causing any visual loss. Long term complications were late bleb fibrosis and progression of cataract. ConclusionGlaucoma surgery had beneficial effects in the majority of patients with advanced glaucoma. Postoperative IOP was in general under control and visual acuity was preserved without any cases of wipe-out.
