Background: To describe the clinical features, visual outcomes, and therapeutic complications of patients with retinal capillary hemangiomas.
Methods: A retrospective, non-comparative, observational case study of patients diagnosed with retinal capillary hemangiomas was conducted. Twelve patients (13 eyes) at Chang Gung Memorial Hospital of Kaohsiung from July 1987 to June 2001 were reviewed. Pre- and post-treatment visual acuity and ocular complications are described.
Results: One patient had bilateral and another had unilateral juxtapapillary hemangiomas. All of the other 10 patients were diagnosed with peripheral retinal capillary hemangiomas. More patients had retinal capillary hemangiomas located in the temporal peripheral retina and all had endophytic growth patterns. No patient met the diagnostic criteria of von Hippel-Lindau disease. Visual acuity levels of peripheral retinal hemangiomas without exudative retinal detachment often remained the same after focal laser treatment. Two patients received vitreoretinal surgery. Patients with juxtapapillary hemangiomas had variable visual outcomes and visual field defects during follow-up.
Conclusion: Early diagnosis of capillary hemangiomas in the retinal periphery and treatment by focal laser produced good visual outcomes. If untreated, the tumors may eventually be complicated with exudative retinal detachment and have a worse visual prognosis even with vitreoretinal surgery.

We compared chorioretinal microvascular of Slow Coronary Flow Phenomenon (SCFP) patients using Optical Coherence Tomography Angiography (OCTA) to healthy controls. We recruited 21 patients from September 2023 until January 2024 from two referral centers. We enrolled 21 age-sex-matched controls retrospectively.

Purpose: To assess the colocalization of ellipsoid zone (EZ) disruption with nonperfusion in choriocapillaris (CC), retinal superficial capillary plexus (SCP), and deep capillary plexus (DCP) in diabetic patients using en face optical coherence tomography (OCT) and OCT angiography (OCTA).
Methods: Macular OCT and OCTA scans (3 × 3 mm) of 41 patients with diabetic retinopathy were obtained using an RTVue XR Avanti instrument. After correcting the shadow artifacts, EZ integrity was assessed in the en face OCT slab using the Gaussian mixture model clustering method compared with the corresponding EZ en face OCT of 11 age-matched normal patients.

Introduction: This study aims to summarize the retinal and choroidal microvascular features detected by optical coherence tomography angiography (OCTA) in the affected and fellow eyes of patients with retinal vein occlusion (RVO).
Methods: A comprehensive search of the PubMed, Embase, and Ovid databases was conducted to identify studies comparing OCTA metrics among RVO, RVO-fellow, and control eyes. Outcomes of interest included parameters related to foveal avascular zone (FAZ) and fovea- and optic nerve head (ONH)-centered perfusion measurements of superficial capillary plexus (SCP), deep capillary plexus (DCP), and choriocapillaris layer.
