If sight cannot be fully restored - Glaucoma

"Early detection and treatment will usually prevent or slow down further damage by glaucoma. If you do experience some sight loss much can be done to help you use your remaining vision as fully as possible. You should ask your optician or optometrist about low vision aids and whether you are eligible to register as sight impaired (partially sighted) or severely sight impaired (blind). Registration can act as your 'passport' to expert help and sometimes to financial benefits. Only the Ophthalmologist can place someone on a partial sighted or blind register."
