摘要：
Purpose: To describe characteristics of choroidal osteomas (CO), using ocular ultrasound, fluorescein angiography, ultra-widefield retinal imaging, ultra-widefield autofluorescence, optical coherence tomography, enhanced-depthimaging OCT, and OCT angiography (OCT-A). Methods: Retrospective, observational case series study. Clinical records from patients with diagnosis of CO who underwent complete imaging evaluation were analyzed. Results: Sixteen eyes from 11 patients were included. Mean patient age was 33.4 years (range 20-61), 72.7% were female, 100% were Hispanic, and 54.5% had unilateral CO. Median visual acuity was 20/150 (range 20/20-2000). CO was completely calcified in 25%, partially decalcified in 50%, and decalcified in 25%. Other features included choroidal neovascularization (18.75%), focal choroidal excavation (12.5%), choroidal depression associated to decalcification (18.75%), thinning of outer retina and photoreceptor layers over decalcified tumor (75%). Decreased fluorescence on FAF was observed in decalcified regions while relatively preserved fluorescence was observed in calcified regions. Conclusions: Nowadays, diagnostic tests provide important information about each stage of choroidal osteoma. Progressive decalcification of the tumor might have a common pathogenic role for development of FCE or choroidal depression. OCT-A/FA proved to be valuable tools for detection of CNV in patients with CO. © 2019 The Author(s).
