Optical Coherence Tomography of the Orbit Through a Staphyloma: A View of Tenon's Capsule, Orbital Fat, and Inferior Oblique Muscle
Optical coherence tomography (OCT) has been used to image anterior and posterior structures of the eye, but it has not been used to image structures behind the sclera. 1,2 Extraocular muscles, especially when hypertrophied from thyroid eye disease, have been described with OCT anteriorly. 3 Patient 1 ( Figure 1A ) has a large staphyloma created by focal treatment of intraocular retinoblastoma. A horizontal cross-section was taken with Heidelberg Spectralis enhanced depth imaging OCT (EDI-OCT) (Heidelberg Engineering) and revealed details normally masked by the retina and choroid. The sclera (white arrow), Tenon's capsule (red arrow), long posterior ciliary nerve (yellow ...
