چکیده
BACKGROUND The term "green cataract" appears in the literature of the 16th century and at the same time it was mentioned that couching a green cataract would not restore the vision. PATIENTS The cases of a 54-year-old women and a 74-year-old man with green cataract and the diagnosis of vitreous hemorrhage and end stage rubeosis iridis with absolute glaucoma and no light perception is recorded. In the second case an enucleation was performed. An iron stain of the lens revealed heavy accumulation of iron in the lens epithelium. CONCLUSION Green cataract is a distinct entity. It is due to the presence of blood pigments from the breakdown of intraocular hemorrhage. It is usually accompanied by rubeosis irides and an absolute glaucoma. The observation, that surgery of these cataracts will not restore light, is also correct.
