Symptoms may include severe pain, nausea, vomiting, blurred vision, and seeing a rainbow halo around lights. This form of glaucoma is a medical emergency and must be treated immediately or blindness could result in one or two days. Secondary glaucoma may produce pain, blurry vision, or halos around lights if it occurs suddenly. Other symptoms may occur, but vary due to the condition causing the glaucoma. Congenital glaucoma may produce an eye that is enlarged, milky in appearance, or bulging.
Juvenile glaucoma produces a symptom pattern similar to open-angle glaucoma.
Pigmentary glaucoma may produce no symptoms. Some people will experience colored haloes around lights, blurred vision or eye pain. Pseudoexfoliation syndrome usually produces no symptoms until the glaucoma is advanced, when loss of vision is noticeable. The glaucoma associated with the condition may produce no symptoms. Neovascular glaucoma may produce no symptoms, but many people experience significant loss of vision with a chronically red, painful eye.
