Abstract
To evaluate the clinical features and outcomes of eyes with peripheral exudative hemorrhagic chorioretinopathy (PEHCR). It was a retrospective case series study. A total of 12 patients (12 eyes) diagnosed with PEHCR at Peking University People's Hospital from October 2016 to December 2019 were included. The clinical data of visual acuity, slit-lamp microscopy, indirect ophthalmoscopy, fundus photography, B-ultrasound, optical coherence tomography, fluorescein fundus angiography and indocyanine green angiography, surgical procedures, therapeutic effects and follow-up were analyzed. Among all 12 patients included, 7 were male and 5 were female. The age was (58.0±8.8) years. All patients had unilateral disease. The right eye was involved in 6 cases and the left eye in 6 cases. All cases presented with vitreous hemorrhage, 9 of which presented with intraocular space-occupying lesions. In the patients with intraocular space-occupying lesions, the maximum basal diameter was (8.3±1.6) mm and the height was (3.5±1.2) mm measured by B-ultrasound. A-scan ultrasonography was characterized by intermediate high reflectivity or intermediate low reflectivity. Fundus fluorescence angiography revealed nonspecific alterations corresponding to the visible fundoscopic changes such as window defects, blockage, staining, but no neovascular membrane. No polyps were found on indocyanine green angiography. All patients received vitrectomy. The intraocular lesions were found to be subretinal bleeding and exudative masses intraoperatively. Two patients had combined cataract surgery; three patients received gas or silicone oil tamponade, and three patients received adjunct intravitreal anti-vascular endothelial growth factor drugs during the follow-up. The follow-up period was (30.0±12.6) months. At the last visit, the visual acuity was improved in 11 patients and remained stable in 1 patient. PEHCR is a peripheral hemorrhagic retinal degenerative disorder that simulates choroidal melanoma and lacks characteristic angiography changes. The overall therapeutic effect and prognosis are good.
