PURPOSE: To study the prevalence of sustained intraocular pressure (IOP)
elevation associated with intravitreal injection of anti-vascular endothelial
growth factor (anti-VEGF) agents. METHODS: Prospective comparative study.
Non-glaucomatous patients scheduled to receive intravitreal injection of
anti-VEGF therapy were recruited from an outpatient eye clinic, Songklanagarind
Hospital between April 2013 and March 2014. The IOP was measured by Goldmann
applanation tonometer before and at 1 hour, 1 week, 1 month, 3 months, and 6
months after injection. The IOP was compared using the repeated measures
analysis. Sustained IOP elevation was defined as either an IOP > 21 mmHg or an
increase from baseline ? 5 mmHg on two consecutive visits. RESULTS: Seventy eyes
of 54 patients met the inclusion criteria. The most common diagnosis was diabetic
macular edema (48%). The mean IOP ± standard deviation (SD) before treatment was
13.7 ± 2.8 mmHg. The means ± SDs after treatment at 1 hour, 1 week, 1 month, 3
months, and 6 months were 11.3 ± 2.6, 13.7 ± 3.6, 14.1 ± 3.3, 14.0 ± 2.3, and
13.7 ± 2.4 mmHg, respectively. A mean of IOP difference at 1 hour postinjection
and at baseline was -2.36 ± 2.5 mmHg (P < 0.001). Four of 70 treated eyes (5.7%)
developed sustained IOP elevation (IOP ? 5 mmHg from baseline on two consecutive
visits). The IOP returned to baseline levels after 1 month, in three eyes. One
eye had sustained IOP elevation at 3 and 6 months follow-up. Thereafter, IOP
returned to baseline level. There was no need of anti-glaucoma medication.
CONCLUSIONS: After receiving intravitreal injection of anti-VEGF agent, a small
proportion of non-glaucomatous eyes developed a sustained IOP elevation without
requiring IOP-lowering treatment. At 1 hour postinjection, there was a
significant reduction of the mean IOP compared with the baseline level.
