The acute symptoms of glaucoma include eye swelling, eye pain, photophobia, excessive tearing, headaches, and blurred vision. A careful eye pressure examination at a hospital outpatient clinic can determine if you have glaucoma, and this examination costs about several dozen yuan. If diagnosed with glaucoma and the intraocular pressure is elevated, early surgical treatment is necessary to avoid the risk of blindness that may result from high intraocular pressure.
