Abstract
PURPOSE: To describe the results of selective laser trabeculoplasty (SLT) in eyes with angle recession glaucoma (ARG). To our knowledge, this is the first report of SLT being used as treatment modality for angle recession glaucoma. Argon laser trabeculoplasty (ALT) was used for ARG but showed a little therapeutic effect. OBSERVATIONS: Retrospective case series of 4 eyes of 4 patients with history of non-penetrating injury to the eye resulted in angle recession glaucoma. All eyes underwent SLT. Post-treatment, the best-corrected visual acuity (BCVA), intraocular pressure (IOP), number of glaucoma medications, additional need for intervention, and complications were recorded. Success of treatment was defined as an IOP reduction of 20% or reduction in medications and maintaining target IOP without further intervention during follow up period of more than 3 months.Mean patient age was 44 years (SD = 9) and 2 out of 4 were females. SLT treatment resulted in decreased IOP from 21 to 12 mmHg in one patient and from 26 to 20 mmHg with reduced medication burden in another patient and reduced medication burden in the third patient who stopped glaucoma medication with no significant change in IOP (from 10 to 14 mmHg) at last follow up visit at 45 months. Two SLT sessions failed in one patient who underwent tube surgery.In the 3 patients with successful treatment, IOP remained controlled for the duration of follow up ranging from 4 to 45 months. CONCLUSIONS AND IMPORTANCE: Predicting IOP outcomes after SLT is difficult in patients with ARG. Success was noted early in the post-treatment period and was maintained for years. Repeating SLT in a case of early failure didn't change the result and is not recommended. A larger study is required to confirm the safety and effectiveness of SLT for ARG.
