Optic pit-like maculopathy in a patient without any detectable disc anomalies

Macular schisis is the splitting of the inner retinal layers at macula, with or without associated detachment. The acquired form of macular schisis is frequently associated with optic disc pit maculopathy, although it could be accompanied by several conditions such as tractional maculopathies, cystoid macular edema, veno-occlusive disease, and shaken baby syndrome. However, a small number of cases of retinoschisis without optic disc pit have been reported elsewhere. Here, we present a patient with acquired macular schisis without high myopia and optic disc abnormality in funduscopic examination and imaging. Macular optical coherence tomography of her left eye revealed schisis of the inner and outer retinal layers and subretinal fluid and choroidal thickness of 426 μm (pachychoroid). Although the optic disc of this patient appeared normal, the probable presumption is that small junctions existed between the macular neuroretinal tissue and the vitreous cavity. Further studies are required to survey the other probable mechanisms of retinoschisis without optic pit with more subjects.
