Abstract:
Objective To comparatively observe features of choroidal osteoma by multimodal fundus imaging methods.Methods This is a retrospective case study.Sixteen patients (16 eyes) with choroidal osteoma were enrolled in this study.The patients included 6 males (6 eyes) and 10 females (10 eyes),with an average age of (30.5±2.4) years.All patients received examination of best-corrected visual acuity,slit lamp microscope,indirect ophthalmoscopy,fundus color photography,fundus autofluorescence (AF),fundus fluorescein angiography (FFA) and spectral domain optical coherence tomography (SD-OCT).The tumors were classified as fresh lesion (clear boundary and rosy tumor with smooth surface) and obsolete lesions (pale and flat tumor with obvious patches).The tumor features of color fundus photography,AF,FFA and SD-OCT were comparatively observed.Results There were 5 fresh lesions and 11 obsolete lesions.Color fundus photography showed the tumor color was orange-red or yellow-white with clear boundary and retinal blood vessels on the surface of the tumor.The color of fresh lesion was rosy.In general,choroidal osteoma shown weak AF,however AF of fresh tumor was slightly stronger than the obsolete tumor,and retinal detachment region showed relatively stronger AF.FFA of fresh tumor indicated uniform intense fluorescence with clear boundary at late stage,much stronger than obsolete tumor.SD-OCT showed mesh-like reflected signal in the choroidal layer,but different from the surrounding choroidal vascular structures.Conclusions The tumor color is orange-red or yellow-white in color funds photography,which shown weak AF.FFA showed mottled hyperfluorescence in the early stage and tissue staining at the late stage.SD-OCT showed mesh-like reflected signal in the choroidal layer.
