Glaucoma in babies and young children is rare, and is very different from adult glaucoma. It causes symptoms of tearing; severe light sensitivity and the eyelids are usually firmly closed (blepharospasm). The eye enlarges and the cornea can look large and cloudy. Children with glaucoma invariably require surgery to lower the intra-ocular pressure and control the disease, but additionally will usually require glasses and sometimes patching to restore vision. The most common surgical procedures are trabeculotomy and goniotomy, but other more invasive procedures may be required.
