[Ocular manifestation of langerhans' cells histiocytosis - case report]

To present a case of a young female suffering from Langerhans' cells histiocytosis of the lungs with ocular involvement. MATERIAL/ RESULTS: Patient was primarily admitted to the ophthalmology department due to bilateral mature cataract. Phacoemulsification did not improved visual acuity. Based on ophthalmological examination, spectral coherence tomography scans and fundus angiography and previous medical history, concomitant advanced changes e.g. optic nerve atrophy and severe obliteration of retinal vessels was revealed

Our case presents one of rare ophthalmic localization of Langerhans, cells histiocytosis within vessels wall and/ or optic nerve that can be potentially the reason of that arterial and vein obliteration and optic nerve atrophy.
