Abstract
AIMS: To study widefield imaging features, analyse risk factors for progression and compare treatment modalities of peripheral exudative haemorrhagic chorioretinopathy (PEHCR). METHODS: Clinical and imaging data from each visit were collected, including near-infrared reflectance, fluorescein angiography, indocyanine green angiography, optical coherence tomography using the Spectralis platform (Heidelberg Engineering). Clinical features and treatment performed were recorded. Lesions were classified according to treatments used and according to the prognostic index of macular involvement (MI) and intravitreal bleeding (IVB). RESULTS: 50 eyes of 35 patients were retrospectively enrolled. Using widefield imaging, peripheral subretinal fluid (SRF) was detected in 31 (62%) eyes and peripheral neovascular networks were detected in 42 (84%) eyes and graded as focal, diffuse and subtotal in 22 (44%), 17 (34%) and 11 (22%) eyes, respectively. MI secondary to PEHCR during the follow-up was documented in 17 (34%) eyes, while IVB occurred in 7 (14%) eyes. Both MI and IVB correlated with peripheral SRF and lesion grade. Active treatment included anti-vascular endothelial growth factor (anti-VEGF) injections, photodynamic therapy (PDT) and combined anti-VEGF and PDT for 13 (26%), 1 (2%) and 18 (36%) eyes, respectively. In eyes with risk factors, anti-VEGF and combined treatment inversely correlated with MI incidence. CONCLUSIONS: In our series, peripheral subretinal exudation and the extension of peripheral involvement represented risk factors for MI in eyes with PEHCR. In those high-risk eyes, active treatment is warranted. © Author(s) (or their employer(s)) 2021. No commercial re-use. See rights and permissions. Published by BMJ.
