Abstract

Purpose: To study the short-term effect of intravitreal injection of bevacizumab on intraocular pressure (IOP).

Methods: Total of 180 patients were included in this study who received intravitreal injection of bevacizumab (1.25mg/0.05ml;Avastin) for various intraocular conditions like macular edema associated with diabetic retinopathy, wet –age related macular degeneration and macular edema in retinal venous occlusions. IOP was measured at just before giving injection and then at 5minutes, 10 minutes, 30 minutes, 60 minutes, 24 hours, day 3 and day 7 post injection using Goldman Applanation tonometry.

Results: Mean pre-injection IOP was 14.41±3.64 mmHg which rose to mean IOP of 39.08±9.54 mmHg (p value-0.000) at 5 minutes after giving injection. Mean IOP  was 32.79±7.66 mmHg (p value-0.000) at 10 minutes,  27.16±6.41 mmHg (p value-0.000) at 30 minutes, 23.26±5.25mmHg (p value 0.000) at 60 minutes, 14.78±3.62 mmHg (p value-0.013) at 24 hours, 14.6±3.59 mmHg (p value -0.164) at day 3 and 14.53±3.55 mmHg (p value-0.327) at day 7 after giving the injection.

Conclusion: we found that IOP can quite high just after giving intravitreal injection which usually comes down to normal range within an hour after injection. so there is no need to give antiglaucoma medication like oral acetazolamide or topical drops to control IOP in these patients.
