Abstract
Introduction & Objectives
Micro-invasive glaucoma surgery with goniotomy is a recent surgical treatment modality that targets
the trabecular outflow to maintain intraocular pressure. This study aims to describe the clinical
outcomes of excisional goniotomy using KDB and to review the published literature regarding a
modified goniotomy technique as a potential surgical treatment modality in Indonesia.
Methods
A cross-sectional descriptive study was conducted in patients that underwent goniotomy stand-alone
or combined with cataract surgery. Main outcome parameters consist of visual acuity, intraocular
pressure (IOP), number of glaucoma medications, and complications during post-operative follow-up.
Results
A total of 7 patients (8 eyes) were included in the study, consisting of 5 (71,4%) males and 2 (28,6%)
females. The mean age of the subjects was 47.7 years. Subjects consisted of primary,
pseudoexfoliative, steroid-induced, and angle-recess glaucoma. Mean pre-operative IOP
measurements showed 20.74 mmHg with visual acuity consisting of 1 (14.3%) mild visual
impairment and 7 (85.7%) severe visual impairment. Postoperatively there was progressive
improvement in the mean IOP to 13.81 and 11.31 mmHg on first-day and one-week follow-up,
respectively. Visual improvement was observed in 2 (28.5%) with mild visual impairment, 3 (42.6%)
with severe visual impairment, and 2 (28.5%) with hand movement due to complications of corneal
edema following phacoemulsification. A week later, visual acuity improved to 4 (57.1%) with mild
visual impairment and 3 (42.9%) with moderate visual impairment.
Conclusion
Goniotomy is a simple surgical method that may be applied in Indonesia as a novel technique to
provide an effective intraocular pressure-lowering effect.
