1.Is it definitely glaucoma if the eyes are swollen and painful? Not necessarily, visual fatigue can also be eye swelling pain, because the treatment of visual fatigue and glaucoma is completely different, the prognosis is also different, so eye swelling pain should go to the regular hospital ophthalmology for detailed examination to rule out whether it is glaucoma or not. 2.Does glaucoma always cause eye swelling and pain? Not necessarily, primary glaucoma is divided into open-angle glaucoma and closed-angle glaucoma, generally open-angle glaucoma rarely has eye distension and eye pain, while acute closed-angle glaucoma attack will have obvious eye distension, eye pain, vision loss, accompanied by headache, nausea, vomiting. 3. Is it possible that a patient with headache, nausea or vomiting has glaucoma? Yes, it is possible. When an acute attack of glaucoma occurs, the eye pressure suddenly rises, causing reflex headache, nausea, vomiting and other symptoms outside the eye. Therefore, if a patient with similar symptoms does not improve after gastroenterology or neurology treatment, the possibility of glaucoma should be considered. 4.Can glaucoma patients see after surgery? No. Once the optic nerve is damaged, it cannot be regenerated for life. The optic nerve is like a wire connecting the eye and the brain, and if the wire is broken, the vision will not improve significantly even after surgery. The purpose of surgery is to control intraocular pressure and prevent further damage to the optic nerve in order to protect the existing vision. Therefore, glaucoma must be diagnosed and treated early. Avoid saving your eyes only when you can’t see. 5.Does glaucoma always require surgery? Not necessarily, the goal of glaucoma treatment is to control the IOP to a safe range. If medication can achieve the goal, of course, you can use the medication for life without interruption, and review the IOP and adjust the amount of medication according to the situation. However, according to the current situation in China, glaucoma patients are often unable to take the required medication for a long time and review it regularly, thus leading to fluctuations in intraocular pressure and continuous damage to the optic nerve, and the cost of lifelong medication is much higher than surgery. Therefore, in China, surgery is the best option once primary glaucoma is diagnosed, but medication can be considered for patients who are in poor systemic condition and not suitable for surgery.
