Glaucoma has been reported in 10-59% of cases.\n\nTreatment\n\nFuch's heterchromic uveitis responds variably to steroids and cycloplegics. The complications of long-term use of these drugs may at times outweigh their potential benefits. Therefore, treatment with topical steroids is given to iritis which is sufficiently active to require the treatment, otherwise, the patient is routinely followed without giving any treatment.\nCataract responds well to most forms of intraocular surgeries, including the standard IOL implantation. Hyphentia may occur because of rubeosis iridis (neovascularization of iris).\nGlaucoma control may be somewhat more problematic, with surgical options indicated for later forms of the disease.", 'role': 'assistant'}]
