INTRODUCTION: The purpose of this study was to describe the anatomical and functional outcome of vascular endothelial growth factor inhibitor (anti-VEGF) treatment in symptomatic peripheral exudative hemorrhagic chorioretinopathy (PEHCR) involving the macula. METHODS: Clinical records from patients seen between 2012 and 2013 at a single academic center were reviewed to identify PEHCR patients receiving anti-VEGF therapy due to disease-associated changes involving the macula. Affected eyes were either treated with consecutive intravitreal injections of anti-VEGF or vitrectomy combined with anti-VEGF followed by pro re nata injections. RESULTS: The mean age of the patients was 76 years (range 70-89 years). In all nine eyes, visual acuity was reduced due to central subretinal fluid. On average, three anti-VEGF injections (range 2-5 injections) were required initially to achieve complete resolution of macular subretinal fluid. In three eyes, subretinal fluid reappeared after an average of 10 months (range 5-16 months), and an average of 2.5 anti-VEGF injections (range 2-3 injections) were necessary to attain complete resolution of macular subretinal fluid a second time. Median visual acuity at the visit before the first injection was 1.0 logMAR (range 2.1-0.4 logMAR) and increased to 0.8 logMAR (range 2-0.1 logMAR) at the last visit. CONCLUSION: Results of this study show that for cases in which PEHCR becomes symptomatic due to macular involvement, anti-VEGF treatment may have drying potential. Although vision was improved in some patients, it remained limited in cases with long-term macular involvement, precluding any definitive functional conclusion. However, we believe that the use of anti-VEGF agents should be recommended in PEHCR that threatens the macula. Due to its often self-limiting course, peripheral lesions should be closely observed. Larger studies are needed in order to provide clear evidence of the efficacy of anti-VEGF therapy in PEHCR.
