ObjectiveTo observe the characteristics of images of optic coherence tomography (OCT) for the macular region of congenital retinoschisis and investigate its significance.MethodsThe data of OCT of 11 patients (20 eyes) with congenital macular retinoschisis diagnosed by direct or preplacedmirror ophthalmoscopy, fundus fluorescein angiography (FFA), and electroretinography (ERG) were retrospectively analyzed.ResultsThe images of OCT showed split in the mid portion of sensory retina at the macula in all eyes. The retina of fovea centralis was divided by the split into two slightly thickening layers. In addition, in a few number of cases, the parafoveal sensory retina which became much thickening with 2 splits, was divided into 3 layers.ConclusionThe characteristic of images of OCT in macular congenital retinoschisis is the split cavity at the middle layer of the retina, and OCT has a high sensitivity in the diagnosis of congenital retinoschisis.
