Abstract
Purpose:
To determine the efficacy of selective laser trabeculoplasty in patients who have undergone prior Descemet's stripping endothelial keratoplasty or penetrating keratoplasty.
Methods:
A prospective chart review of patients who underwent selective laser trabeculoplasty (SLT) from January 2010 until July 2014 at Rush Medical Center in Chicago was completed. The preoperative intraocular pressure (IOP) and post-operative IOP at 1, 3, 6, 12, 18, and 24 months was documented. Patients with an IOP greater than 24, or greater than 10 mmHg above baseline were treated with SLT as first line treatment, or as adjunctive treatment in patients already started on topical medication to lower their IOP. Baseline and yearly Humphrey visual fields and spectral domain OCT were obtained.
Results:
A total of six patients, eight eyes were included in our study with an average age of 58 years old and an average follow up period of 9.75 months. Prior to the SLT, the average drops per patient were 2.75 drops and the average intraocular pressure was 15.75. At six weeks after SLT, the average drops per patient were 2.5 drops and the average intraocular pressure was 13.5. At six months, the average drops per patient were 1.5 and the average intraocular pressure was 14.7. A total change in number of drops among our patients was 1.25 drops.
Conclusions:
SLT is an effective way to treat elevated IOP in patients Descemet's stripping endothelial keratoplasty or penetrating keratoplasty. Further studies in a larger study group are needed.
