Abstract

Purpose : To describe the longitudinal outcomes of a safety-net patient population with neovascular glaucoma (NVG) treated with glaucoma drainage implants (GDIs).

Methods : We performed a retrospective observational study including eyes that received GDIs for NVG at LAC+USC Medical Center from 2008-2018. Exclusion criteria were an uncertain diagnosis of NVG, history of prior GDI in the study eye, or follow-up of less than one year. Patients were stratified into Ahmed (AGV) and Baerveldt (BGI) groups. The primary outcome was surgical success defined as the preservation of light perception, intraocular pressure (IOP) below 22 mmHg, and no additional glaucoma intervention. Secondary outcomes included visual acuity (VA), intraocular pressure (IOP), and medications prescribed at 1-, 2-, and 3-year intervals postoperatively. Data were compared between groups using Student’s t-test for continuous variables and Fisher’s exact test for categorical variables.

Results : 162 eyes from 151 patients met inclusion criteria and, of these eyes, all were reported at 1 year, 107 at 2 years, and 66 at 3 years. Mean age was 53.2 and 88% were Hispanic. Age and ethnicity did not vary between groups (p = 0.49 and 0.60). Preoperative IOP was 39.4 mmHg in AGVs and 32.7 mmHg in BGIs (p = 0.0003), but there was no significant difference in preoperative VA (p = 0.28). No significant differences were found in success rate between the groups at 1, 2 and 3 years postoperatively with AGVs reporting success in 75%, 60% and 59% respectively, and BGIs in 82%, 76% and 64%. In the subgroup of successful GDIs, there was not a statistically significant difference in the number of classes of drops used at each follow-up interval, though there was a trend toward a lower drop burden in the BGI group (p = 0.14, 0.15, 0.41 at 1, 2 and 3 years); VA and IOP did not vary significantly.

Conclusions : There were no significant differences found in longitudinal outcomes of AGVs and BGIs in the context of NVG.
