Three-dimensional Optical Coherence Tomography Imaging and Treatment of Glaucomatous Optic Nerve Head Defects Associated with Schisis-like Maculopathy

Abstract

We present the three-dimensional (3D) spectral-domain optical coherence tomography (SD-OCT) findings of schisis-like maculopathyassociated with structural changes of the optic nerve (ON) head as well as the treatment outcomes of a case of advanced glaucoma. Inaddition to ophthalmological examination, B-scan and 3D-SD-OCT images of the ON head, peripapillary retina, and the macula wereobtained. The B-scan images only detected typical retinoschisis findings. However, the 3D-SD-OCT images of the ON head revealeddefects of various sizes, shapes, and depths at the outer wall of the prelaminar and laminar regions of the ON canal. The 3D images wereable to establish that these defects were both adjacent to and interconnected with the retinal layers. The patient successfully received3D-SD-OCT-guided thermal laser treatment that is used in congenital optic disc pits complicated with macular schisis. In brief, 3D-SDOCTis very useful for demonstrating the ON head defects that can lead to schisis-like maculopathy in cases of advanced glaucoma.
