Macular pits and scleral dehiscence in highly myopic eyes with macular chorioretinal atrophy.
BACKGROUND
In highly myopic eyes, it is possible to observe the entire thickness of the sclera using swept-source optical coherence tomography. The peculiar scleral alterations observed using swept-source optical coherence tomography within the area of macular chorioretinal atrophy were reported.


METHODS
The area of macular chorioretinal atrophy was scanned by swept-source optical coherence tomography in two patients with pathologic myopia.


RESULTS
In one of the two patients, three pitlike clefts were observed within the area of the atrophy. The deepest pit was 715 μm in depth from its opening. In the other patient, the sclera seemed to dehisce within the area of macular atrophy. In the adjacent sections of the scleral dehiscence, choroidal thickening was observed.


CONCLUSIONS
These suggest that in the area of macular chorioretinal atrophy, the scleral curvature could be severely altered. The area of chorioretinal atrophy could expand more than the surrounding area due to a lack of RPE, Bruch membrane, and choriocapillaris.
