Microhook
trabeculotomy (μLOT), recently developed by Tanito belongs to minimally invasive
glaucoma surgery and contributes to intraocular pressure (IOP) control in eyes with
glaucoma resistant to medical
therapy. In this study, we aimed to investigate the effectiveness and safety of μLOT for uveitic
glaucoma. The medical records of consecutive 36 eyes from 30 patients who underwent μLOT and were followed up over post-operative 1 year were reviewed. The surgical success (IOP = 5-20 mmHg and ΔIOP ≥ 20% with additional
anti-glaucoma drugs) was achieved in 67% of eyes at post-operative 12 months. The median IOP significantly decreased from 30.5 mmHg pre-operatively to 15 mmHg at 12 months post-operatively (p = 0.001), and the median
glaucoma drug score changed from 5 pre-operatively to 2.5 at 12 months post-operatively (p = 0.301). Intraocular
inflammation scores at post-operative 6 weeks did not show a significant worsening as compared to pre-operatively, and 8 (22%) eyes exhibited exacerbation of
inflammation during the 12-month follow-up period. Post-operative complications were confirmed in 58% of eyes, but most of them were mild and transient or successfully managed. With its favorable benefit-risk profile, μLOT would be an option worth considering as the first
glaucoma surgery for uveitic
glaucoma.
