PURPOSE: To present a case of unilateral stellate nonhereditary idiopathic foveomacular retinoschisis in a patient with macular telangiectasia (MacTel) Type 2.
METHODS: Single-patient case report.
RESULTS: A 61-year-old female white patient was referred to our clinic with metamorphopsia and reduction of visual acuity over a period of 2 months on her right eye. Ocular findings in her right eye included reduced best-corrected visual acuity of 20/63 Snellen, foveomacular retinoschisis with extension to the lower middle periphery, central elevation of the neurosensory retina, and macular telangiectasia (MacTel) Type 2. Other causes of foveomacular retinoschisis, such as glaucoma, myopic degeneration, optic or scleral pit, X-linked juvenile retinoschisis, degenerative retinoschisis, and vitreomacular traction, were ruled out. The patient had no history of niacin or taxane medication, which may cause rather similar appearing cases of cystoid macular edema without leakage in fluorescein angiography. Because of the unilateral presentation, uneventful medical history, female sex, and the absence of known hereditary diseases or retinal pathologies in the patient's family history, hereditary predisposition appears to be highly unlikely.
CONCLUSION: To our knowledge, this is the first reported case of stellate nonhereditary idiopathic foveomacular retinoschisis in combination with MacTel Type 2. Whether or not MacTel Type 2 plays a role in the development of stellate nonhereditary idiopathic foveomacular retinoschisis or has an impact on its clinical course requires further investigation. Furthermore, we suggest a significant involvement of Henle fiber layer in the process of intraretinal expansion in optical coherence tomography, in accordance with the most recent published nomenclature.
