Clinical and multifocal-electroretinographic findings of congenital tilted disc syndrome associated with choroidal neovascularization: a case report

Abstract

Purpose: To report a case of a tilted disc syndrome associated with choroidal neovascularization.

Methods: A 55-year-old male patient presented with blurred vision and metamorphopsia of the left eye. He underwent complete ophthalmologic examination, fluorescein angiography, optical coherence tomography (OCT) and multifocal-electroretinogram (mf-ERG).

Results: All features are consistent with a tilted disc syndrome complicated with a small neovascular membrane. OCT confirmed the presence of a serous retinal detachment. Mf-ERG confirmed a decrease of electrical activity of the photoreceptors in area 1 (fovea). The patient refused to be treated.

Conclusion: Macular serous retinal detachment due to subretinal leakage is a rare complication of tilted disc syndrome. To the author's knowledge, this is the first time a tilted disc syndrome with choroidal neovascularization is documented by means of OCT and mf-ERG. These are the only objective tools in order to assess objectively the anatomical and functional damage accordingly.
