Recurrent Tube Erosions with Anti-Vascular Endothelial Growth Factor Therapy in Patients with Age-Related Macular Degeneration.
Journal Article (Journal Article)
PURPOSE: To determine the rates of primary and recurrent glaucoma tube shunt erosions in patients with age-related macular degeneration (AMD) receiving anti-vascular endothelial growth factor (VEGF) intravitreal injections. DESIGN: Retrospective case series. PARTICIPANTS: Patients with AMD who underwent tube revision for erosion at the Duke Eye Center from January 1, 1999, to January 1, 2019, were identified. Patients with and without anti-VEGF injections were compared. METHODS: Patient demographics, ocular diagnoses, glaucoma tube shunt types and locations, and dates of glaucoma surgeries and anti-VEGF injections were collected. Statistical analyses were performed with P < 0.05 as significant. MAIN OUTCOME MEASURES: Outcome measures included the number of tube erosions, time from anti-VEGF injection to tube erosion, and secondary complications after tube revisions. RESULTS: A total of 150 patients with AMD with anti-VEGF (309 tubes) and 262 patients with AMD without anti-VEGF (459 tubes) were identified. There was no statistically significant difference in the number of tube erosions in patients with anti-VEGF (15 tubes, 4.8%) versus without anti-VEGF (12 tubes, 2.6%) (P = 0.10). However, patients receiving anti-VEGF had on average a greater number of tube erosion events (2.1±0.7 events) compared with patients without anti-VEGF (1.3±0.7, P < 0.01). Ten patients (91%) received concurrent anti-VEGF injections at the time of tube erosion, and the average duration of prior anti-VEGF therapy was approximately 2 years. Tube erosion was noted 46.5±60.7 days from the preceding anti-VEGF injection. Secondary complications after tube revision in the anti-VEGF group included 5 explanted tubes for recurrent erosions. CONCLUSIONS: Our results suggest intravitreal anti-VEGF injections are linked to higher rates of recurrent glaucoma tube erosions in patients with AMD. The majority of patients received chronic and serial anti-VEGF injections. Thus, additional consideration should be given to glaucoma surgical planning in patients receiving anti-VEGF injections, especially in those with a primary tube erosion.
