PURPOSE:: To detect, describe, and classify the morphologic characteristics of astrocytic hamartomas in tuberous sclerosis complex, using both spectral-domain optical coherence tomography (OCT) and infrared images. METHODS:: Ten subjects (20 eyes) with tuberous sclerosis complex underwent a complete ophthalmologic examination and multimodality imaging with spectral-domain OCT and infrared images. The imaging protocol included a 30°scan angle of the posterior pole and of the four quadrants. Line scans, detail, raster, and posterior pole patterns were used. The identified astrocytic hamartomas were described and characterized qualitatively and quantitatively. RESULTS:: Forty-four hamartomas were detected in 8 patients. In five cases, lesions were bilateral. Thirty of these hamartomas had not been revealed by previous ophthalmoscopy. Through multimodality imaging, it was possible to define multiple lesions with characteristic optical reflective qualities. All the 44 hamartomas were measured and morphologically characterized in terms of the type of tumor, retinal and/or vitreous involvement, calcifications, and posterior optical shadowing. CONCLUSION:: The combined imaging with spectral-domain OCT and infrared images improves the detection of hamartomas if compared with the spectral-domain OCT technique alone. Moreover, a new subtype of hamartoma is proposed to complete a previous classification based on OCT.
