Periocular triamcinolone acetonide injection for treating polypoidal choroidal vasculopathy concurrent with hemorrhagic retinal detachment

To investigate the clinical efficiency of periocular triamcinolone acetonide (TA) injection for treating polypoidal choroidal vasculopathy (PCV) concurrent with hemorrhagic retinal detachment (HRD). Twenty-two cases confirmed with PCV concurrent with HRD characterized by massive subretinal hemorrhage and exudation presented to our department from January 2015 to May 2017 were included in this study. The initial vision varied from counting finger to 0.2. All cases were randomly divided into TA group (n = 12), which received periocular TA injection per month, and anti-VEGF group (n = 10), which were treated by anti-VEGF intravitreous injection per month. The patients were followed up for 6 months, in which fundus examination and visual acuity along with optical coherence tomography (OCT) were carried out. The treatment effect is divided into the following categories. Cure was defined as the elimination of subretinal hemorrhage and exudation accompanied by retinal edema and choroidal neovascularization (CNV) extinction and rise of visual acuity. Improvement was characterized by alleviation of subretinal hemorrhage and exudation accompanied by retinal edema and CNV reduction and rise of visual acuity. Ineffective means remained subretinal hemorrhage and exudation in fundus and no improvement of visual acuity, and polypoid lesions in OCT images. Among the 12 cases in TA group, 1 case was treated by periocular injection of TA twice, and 11 cases were treated by 3 times injection. After that, 3 cases (25%) were cured, 8 cases (66.7%) got improvement, and only 1 case (8.3%) showed no response. Although among 10 cases in the anti-VEGF group, 3 cases were treated by anti-VEGF intravitreous injection twice. Seven cases were treated by 3 times injection. After that, 4 cases (40%) got improvement, and the other 6 case (60%) showed no response. All patients showed no recurrence in the 6-month follow-up. No complications were noticed under periocular injection or intravitreous injection. Periocular TA injection is effective for treating PCV concurrent with HRD.
