a 32-year - old healthy caucasian lady presented complaining of recent deterioration of vision in her left eye . at presentation , her best corrected visual acuity ( bcva ) was 20/20 in her right eye and counting fingers in her left eye ( le ) . fundus examination and fluorescein angiography revealed findings consistent with arteriovenous communications of the retina or racemose hemangioma , in the posterior pole of the le with the presence of macular ischemia . complete and systemic examination was unremarkable , excluding the possibility of wyburn - mason syndrome . eight years after presentation , findings and bcva in the le have remained stable , with no extension of the retinal ischemia or development of neovascularization . although extensive retinal ischemia has been reported to result in complications such as retinal or iris neovascularization , in our case the macular ischemia has not expanded further over a period of 8 years . however , due to this macular ischemia the patient unfortunately lost her central vision . racemose hemangioma is rare . the development of extensive retinal ischemia including macular ischemia resulting in rubeosis has been reported . we describe a case of racemose hemangioma which spontaneously developed macular ischemia alone , resulting in poor visual acuity . this finding has remained stable over a follow - up period of 8 years with no further complication . a 32-year - old healthy caucasian lady presented complaining of recent deterioration of vision in her left eye ( le ) . at presentation , her best corrected visual acuity ( bcva ) was 20/20 in her right eye and counting fingers in her le . the anterior segment and intraocular pressures were normal in both eyes . fundus examination and fluorescein angiography revealed findings consistent with arteriovenous communications of the retina or racemose hemangioma , in the posterior pole of the le with the presence of macular ischemia ( figures 1 and 2 ) . complete and systemic examination including mri scan was unremarkable , excluding the possibility of wyburn - mason syndrome with arteriovenous malformations of the optic nerve and midbrain . eight years after initial presentation , findings and bcva in the le have remained stable , with no extension of the retinal ischemia or development of neovascularization . the lesions have been reported either to remain static or regress12 or to enlarge gradually . vision may be affected directly due to macular involvement or by producing hemorrhage or exudation.3,4 based on archer et al the angioma in our case was grade 3 , although there were no systemic findings.5 we present a case of racemose hemangioma which spontaneously developed macular ischemia . although extensive retinal ischemia has been reported to result in complications such as retinal or iris neovascularization,1 in our case the macular ischemia has not expanded further over a period of 8 years . however , due to this macular ischemia the patient unfortunately lost her central vision . it has been postulated that either an enlarged malformation using part of the blood supply of the retina may cause ischemia , or there was a partial thrombosis which caused circulatory stasis within the lesion.6,7
purposeto report a rare case of racemose hemangioma which developed spontaneous macular ischemia.methodsa 32-year - old healthy caucasian lady presented complaining of recent deterioration of vision in her left eye . at presentation , 
 her best corrected visual acuity ( bcva ) was 20/20 in her right eye and counting fingers in her left eye ( le ) . 
 fundus examination and fluorescein angiography were performed . 
 the patient had regular follow - up appointments over a period of 8 years.resultsfundus examination and fluorescein angiography revealed findings consistent with arteriovenous communications of the retina or racemose hemangioma , in the posterior pole of the le with the presence of macular ischemia . 
 complete and systemic examination was unremarkable , excluding the possibility of wyburn - mason syndrome . 
 eight years after presentation , findings and bcva in the le have remained stable , with no extension of the retinal ischemia or development of neovascularization.conclusionalthough extensive retinal ischemia has been reported to result in complications such as retinal or iris neovascularization , in our case the macular ischemia has not expanded further over a period of 8 years . however , due to this macular ischemia the patient unfortunately lost her central vision .
