摘要
Objective: To compare adverse intraocular pressure (IOP) spikes in patients receiving intravitreal triamcinolone acetonide (IVTA) in 2 cohorts: (i) patients who underwent a topical prednisolone acetate trial (PAT) without incurring a short-term IOP rise, and (ii) control patients who did not undergo a PAT.
Design: Retrospective cohort study.
Participants: Charts of all patients who underwent any intravitreal injection during the study period were reviewed (n = 1150).
Methods: Patients in the PAT group received a 6-week course of prednisolone acetate 1% 4 times per day and had an IOP that did not rise above 25 mm Hg or above 8 mm Hg over the IOP in the contralateral eye. Patients undergoing a PAT and having a short-term IOP rise were not studied. Control patients did not receive a PAT. All patients received 12-20 mg of IVTA. Patients were followed for a minimum of 6 weeks and follow-up lasted for 1 year or until intraocular surgery or another IVTA injection was performed.
Results: There were 97 patients in the PAT cohort and 75 control patients. Patients in the PAT cohort had a lower proportional rise between maximum IOP and baseline (43%) compared with controls (64%) (p = 0.035). Patients in the PAT group also had a lower risk of incurring a 40% (p = 0.05), 60% (p = 0.018), and 100% (p = 0.045) increase in maximum IOP (vs baseline) compared with controls and were less likely to require glaucoma filtration surgery (p = 0.035).
Conclusions: Patients undergoing a PAT who did not have a subsequent short-term IOP rise had a lower risk of severe IOP spikes after IVTA compared with those patients receiving IVTA but not having undergone a PAT.
