MULTIMODAL IMAGING OF CHOROIDAL AND OPTIC DISK VESSELS NEAR OPTIC DISK PITS.

PURPOSE: To describe modern multimodal imaging of the choroidal and optic disk vessels in optic disk pits.

METHODS: Case reports of four patients with optic disk pit who underwent multimodal imaging of the optic pit and surrounding structures. Patients included in this article were found to have optic disk pits and subsequently underwent multimodal imaging.

RESULTS: Cilioretinal arteries were present in two of the four cases (50%). SPECTRALIS optical coherence tomography showed intraretinal and subretinal fluid in all cases. Small vessels in the choroid and in the disk around the pit were also present in all cases through optical coherence tomographic angiography. Confocal fluorescein angiographic imaging in the first case showed leakage from the vessels adjacent to the optic disk pit.

CONCLUSION: Modern multimodal imaging shows that there are anomalous vessels in and around an optic pit. Whether these vessels affect the development of optic pit, maculopathy needs to be further evaluated.
