RETINAL CAVERNOUS HEMANGIOMA DOCUMENTED BY SPECTRAL DOMAIN OPTICAL COHERENCE TOMOGRAPHY AND CONFOCAL SCANNING LASER OPHTHALMOSCOPE RETRO-MODE IMAGING

PURPOSE To report a case of retinal cavernous hemangioma documented by spectral domain optical coherence tomography and retro-mode retinal imaging by confocal scanning laser ophthalmoscope. METHODS Clinical examination, fluorescein angiography, spectral domain optical coherence tomography, and scanning laser ophthalmoscope retro-mode imaging were performed. RESULTS Fundus examination of the left eye of an asymptomatic 39-year-old woman showed an irregularly elevated dark red lesion with a cluster of various-sized saccular aneurysms. The retinal cavernous hemangioma lesions were in the upper vascular arcade. A late-phase fluorescein angiography image showed a typical finding, known as fluorescence capping, characterized by incomplete perfusion because of plasma-erythrocyte separation, which was seen in some larger aneurysms. Spectral domain optical coherence tomography showed that various-sized dilated cystic spaces corresponded to the aneurysms. The image showed the horizontal line, which corresponded to the fluorescence capping in some larger aneurysms. Scanning laser ophthalmoscope retro-mode images showed the individual sizes and septum of the aneurysms. The image also showed the characteristic dots-and-lines pattern around the retinal cavernous hemangioma at the corresponding area of inner retinoschisis attributed to the aneurysms without outer retinoschisis on the spectral domain optical coherence tomography images. CONCLUSION Spectral domain optical coherence tomography and scanning laser ophthalmoscope retro-mode imaging may be useful for evaluating the pathophysiologic features and the full extent of the retinal cavernous hemangioma.
