Purpose
To evaluate the efficacy of repeat selective laser trabeculoplasty (SLT) in African American patients.
Methods
A retrospective chart review of 50 eyes of 22 African American patients who underwent repeat SLT. Mean intraocular pressure (IOP) was measured after SLT 1 and SLT 2 up to 30 months after each SLT.
Results
SLT 2 was performed 19.0+/-12.9 months after SLT 1. The results are summarized in Table 1. After SLT 1, mean IOP was reduced from 20.5+/-5.10 mmHg to 18.5+/-2.97 mmHg at 6-9 months, 17.8+/-4.25 mmHg at 12-15 months, and 15.4+/-3.06 mmHg at 21-30 months. After SLT 2, mean IOP was reduced from 18.9+/-3.38 mmHg to 16.5+/-5.14 mmHg at 6-9 months (p=0.07), 16.0+/-2.83 mmHg at 12-15 months (p=0.01), and 15.4+/-5.32 mmHg at 21-30 months (p=0.03). The percentage of patients achieving ≥20% IOP reduction from baseline IOP after SLT 1 and SLT 2 is shown in Table 2.
Conclusions
Repeat SLT successfully lowers IOP in African Americans at 12-15 months and 21-30 months.
