Assessment of interocular symmetry of choroidal vascularity index and thickness in patients with systemic sclerosis: a prospective study.

Purpose: Systemic sclerosis (SSc) affects blood vessels, internal organs, and skin. In ophthalmology, SSc impacts the choroid. The choroidal vascularity index (CVI) measures the vascular component of the choroid and may serve as a biomarker for the disease staging and prognosis.

Macular choroidal thickness, volume, and vascularity index in patients with systemic sclerosis.

Purpose: The aim of this study was to investigate choroidal parameters in patients with systemic sclerosis (SSc) using enhanced depth imaging spectral-domain optical coherence tomography (EDI-SD-OCT) and to determine their relationships with clinical variables and ocular features.

Methods: Thirty-three patients with SSc and 40 controls were enrolled. The groups did not differ with regard to age, sex, and axial length.
