Retinal vascular lesions in two patients with prolapsed mitral valve leaflets

Two patients with retinal vascular lesions had mid-late systolic clicks on cardiac auscultation, suggesting the diagnosis of prolapsed mitral valve. The first patient demonstrated an inferonasal arteriolar branch occlusion secondary to embolization; the second patient had a central vein occlusion with multiple hemorrhages, glial proliferative tissue, and retinal neovascularization. This report describes the association between the prolapsed mitral valve syndrome and retinal vascular lesions.
