An unusual case report of mitral valve apparatus sparing left atrial appendage vegetation presenting as endogenous endophthalmitis

Abstract

Ocular manifestations of infective endocarditis are nonspecific and rare. Endophthalmitis, retinal artery occlusion, Roth spots and vitreal and retinal infiltrations can all be seen with infective endocarditis. Also, infective endocarditis involving the left atrial appendage with no involvement of the mitral valve apparatus is a rarity. Here we report a case of infective endocarditis of the heart involving the left atrial appendage presenting with features of endogenous endophthalmitis which ultimately progressed to phthisis bulbi with subtle cardiac symptoms in a previous healthy young adult. Infective endocarditis involving the left chambers of the heart carries an inherent high risk of systemic embolization. Panophthalmitis which is considered to be the most severe form of endogenous endophthalmitis is a rare presenting feature. Although a definitive treatment algorithm is lacking, early surgery and parenteral antibiotics along with local antibiotic injections could help to save the vision.
