Long-term effect of anti-vascular endothelial growth factor injections on intraocular pressure

OBJECTIVE: There is a substantial debate in the ophthalmology community about whether anti-vascular endothelial growth factor (VEGF) injections result in a long-term increase in intraocular pressure (IOP). DESIGN: We performed a retrospective study to investigate how the number and timing of intravi...

description OBJECTIVE: There is a substantial debate in the ophthalmology community about whether anti-vascular endothelial growth factor (VEGF) injections result in a long-term increase in intraocular pressure (IOP). DESIGN: We performed a retrospective study to investigate how the number and timing of intravitreal injections in patients with age-related macular degeneration (AMD) and diabetic macular edema (DME) affect IOP over time. METHODS: We collected long-term IOP data on patients receiving anti-VEGF injections at our institution. Patients over the age of 40 years who received injections for AMD (n = 76) or DME (n = 55) were included. Patients were grouped according to indication as well as number of injections received (1–3, 4–6, 7–9, or 10+ injections). IOP measurements were then placed into time points (0–6, 6–12, 12–18, 18–24, or 24+ months) and compared to the preinjection average IOP. RESULTS: For patients with DME, average preinjection IOP was 15.7 mmHg. At 24+ months after injection, the average IOP was 15.2 (P = 0.68) for patients receiving 1–3 injections, 16.8 (P = 0.23) for 4–6 injections, and 14.4 (P = 0.66) for 7–9 injections. For patients with AMD, average initial IOP was 15.6 mmHg. At 24+ months after injection, the average IOP was 12.6 (P = 0.97) for 1–3 injections, 14.9 (P = 0.96) for 4–6 injections, 14.8 (P = 0.84) for 7–9 injections, and 15.7 (P = 0.56) for 10+ injections. CONCLUSIONS: There was no increase in IOP over time for AMD or DME patients, regardless of how many injections they received. For patients receiving unilateral injections, there was no increase in IOP in the injected eye when compared to the noninjected eye.
