| Résumé: | James M Osher,1,2 Robert A Sisk,1,2 Michael R Petersen21Department of Ophthalmology, University of Cincinnati, 2Cincinnati Eye Institute, Cincinnati, OH, USAAbstract: We report three cases of idiopathic macular telangiectasia type 2 with temporally decentered preretinal hemorrhage as the presenting sign. The preretinal blood obscured the telangiectatic vessels such that the diagnosis was only evident by fluorescein angiography of the fellow eyes, which had near-normal vision. The preretinal hemorrhage was associated with Valsalva maneuver in one patient and with type 3 subretinal neovascularization in one patient. We speculate that the vascular dilations in idiopathic macular telangiectasia type 2 may increase patients’ susceptibility to rupture and hemorrhage with increased venous pressure.Keywords: idiopathic macular telangiectasia, juxtafoveal telangiectasia, preretinal hemorrhage, Valsalva retinopathy |
