Optic coherence tomography of optic disk pit maculopathy.

PURPOSE

To define the structure of optic disk pit maculopathy.

METHODS

A patient was examined with optic coherence tomography before and after an intravitreal gas tamponade.

RESULTS

Before intravitreal gas injection, optic coherence tomography defined a separation between the inner and outer layers of the retina that connected with the optic disk pit. An outer retinal layer detachment that centered on the fovea was also present. After pneumatic displacement of the intraretinal and subretinal fluid, optic coherence tomography disclosed that the two layers were opposed and in contact with the retinal pigment epithelium.

CONCLUSIONS

Optic coherence tomography confirmed the two-layer structure of optic disk pit maculopathy and demonstrated the positive effect of pneumatic displacement.
