Retinoschisis at macular area in highly myopic eye by optic coherence tomography

To improve our understanding of macular schisis in highly myopic eyes.

From 2002.6-2003.12, the highly myopic eyes (> 6D) which has macular schisis found by OCT at our hospital were included in the study. Each eye then received further examinations including visual acuity, refractive error and ultrasonography. Then the results were analyzed to find the characteristic of the entity.

During that period, OCT found macular schisis in 38 highly myopic eyes from 36 patients. Their vision was low, and their average axial length and refractive error were 29.6mm and -10.5D respectively. The appearance and the area of the schisis are different among the eyes. But the schisis can be largely divided into two types: inner and outer schisis. They can exit independently or concurrently in the same eye. And the schisis was often accompanied by other macular findings, like retinal detachment, macular hole.

Macular schisis in highly myopic eyes is not uncommon in the clinic. OCT is useful in its diagnosis.
