Spectral-domain optical coherence tomography of astrocytic hamartomas in tuberous sclerosis
Retinal astrocytic hamartomas are benign tumors of the retinal nerve fiber layer (NFL) that may be found in association with tuberous sclerosis (TS). We describe the spectral-domain optical coherence tomography (SD-OCT) features of type 1 astrocytic hamartomas in a child with TS that may aid in the diagnosis and follow-up of these lesions. Gradual, dome-shaped hyper-reflective elevations of the retinal NFL were seen on SD-OCT with subtle shadowing of the underlying tissues. In addition, the vitreous cortex showed focal adhesions to the surface of the tumor.
