Background/PurposeTo analyze the prognostic factors for ocular hypertension after posterior subtenon injection of triamcinolone acetonide (PSTA) for the treatment of diabetic macular edema (DME).MethodsPatients who received PSTA for DME from January 2006 to December 2011 were enrolled retrospectively and were followed until December 2012 in one hospital. Modified Cox regression models were used to analyze the factors associated with ocular hypertension, which was defined as an intraocular pressure > 21 mmHg after PSTA.ResultsA total of 180 PSTA injections were given to 114 eyes from 73 adults with DME. During a mean follow-up of 50.4 weeks after each injection, ocular hypertension occurred in 20.6% of injections (28.1% of eyes). Treatment-naïve patients with proliferative diabetic retinopathy (PDR) had a higher risk of ocular hypertension after PSTA than those with nonproliferative diabetic retinopathy (NPDR) [hazard ratio (HR) = 3.255, p = 0.030]. Intravitreal injection of bevacizumab (IVB) before PSTA had a significant effect in lowering the risk of ocular hypertension after PSTA in patients with PDR who had received panretinal photocoagulation (PRP) (HR = 0.107, p = 0.035). Both prompt PRP and IVB following PSTA had a protective effect against ocular hypertension in treatment-naïve patients with PDR (HR = 0.086, p = 0.0002 and HR = 0.155, p = 0.049, respectively).ConclusionTreatment-naïve patients with PDR had a higher risk of ocular hypertension after PSTA than those with NPDR. Bevacizumab and prompt PRP both had a protective effect against ocular hypertension after PSTA in patients with PDR.
