First of all, let’s be clear: glaucoma is a lifelong disease, so don’t stop reviewing it just because you’ve had surgery; you must review it routinely after surgery. Remember: Glaucoma must be reviewed regularly after surgery. Although the IOP is temporarily well controlled, it does not mean that it is permanently well controlled. Glaucoma is a progressive disease, and even after glaucoma surgery, even successful glaucoma surgery, you must pay attention to regular follow-ups. Even if the IOP is normal, the visual field is not always under control. Therefore, it is important to check IOP and visual field at the time of review. Especially the visual field examination. Glaucoma is a disease that can make a glaucoma patient blind, and it is possible that between painlessness, the visual field of vision has been lost. Once the damage to the optic nerve is severe, the gods cannot save it. It is painful to see patients who have lost their eyesight due to late detection of glaucoma or inadequate treatment in outpatient clinics. If there is redness and pain in the eye, accompanied by headache, nausea, vomiting and loss of vision, it is important to go to the hospital in time, even at night! Some patients stop taking the medication after their eye pressure has returned to normal, which is very wrong! Glaucoma patients need lifelong medication, stopping the medication without permission, the eye pressure will rise!
