To evaluate the long-term intraocular pressure (IOP) changes after intravitreal injection of bevacizumab for age-related macular degeneration.
A total of 83 eyes that received intravitreal injections of bevacizumab for age-related macular degeneration were enrolled. IOP measurements at baseline, 6, 12, 18, and 24 months, and at the last follow-up after injection were analyzed. On the basis of the median number of injections, the changes in IOP were compared.
The mean number of injections was 3.71±1.62. There was no significantly higher elevation than baseline IOP (14.11±2.76 mm Hg) after multiple intravitreal injections of bevacizumab (P>0.05). In the group which had ≥4 injections, mean IOP measurements were not higher compared with the group which had <4 injections during the follow-up period (P>0.05). In the patients with preexisting glaucoma (3 eyes), there were no significant increases of IOP during the follow-up period.
IOP elevation was not observed during the long-term follow-up period. In addition, the numbers of injection and preexisting glaucoma did not affect IOP changes.
