Combination microinvasive glaucoma surgery: 23-gauge cystotome goniotomy and intra-scleral ciliary sulcus suprachoroidal microtube surgery in refractory and severe glaucoma: A case series

Abstract

The purpose of this study is to present the efficacy of combined goniotomy and intra-scleral ciliary sulcus suprachoroidal microtube insertion surgery in five patients with refractory and severe glaucoma. This Single-center, case series of five (5) Black and Afro-Latino patients with refractory and severe glaucoma who underwent combination microinvasive glaucoma surgery; 23-gauge goniotomy and intra-scleral ciliary sulcus suprachoroidal microtube insertion. Patients who underwent the above procedure with 6 months follow-up were included. Investigated parameters were intraocular pressure (IOP), number of medications, visual field findings, and visual acuity. Five patients with moderate to severe refractory glaucoma who had undergone 23-gauge cystotome goniotomy and ciliary sulcus suprachoroidal microtube had a reduction of IOP by 32% (mean pre-op and post-op 16.6 mmHg and 11 mmHg, respectively) and a reduction of ocular medications by 61.5% (mean pre-op and post-op of 5.2 and 2.4, respectively). All patients had either stabilization or improvement of their visual fields. Four of the five patients also showed an improvement in visual acuity. This novel approach of combined 23-gauge goniotomy and intra-scleral ciliary sulcus suprachoroidal microtube insertion surgery is safe and is an affordably effective means of managing patients with moderate to advanced refractory glaucoma, leading to a reduction in IOP and the number of medications with no serious adverse effects.
