If the intraocular pressure is still high after glaucoma surgery, it can be improved by massaging the eyeball, filtering vesicle separation, medication and reoperation, and the specific treatment is related to the patient’s condition. 1. Massage the eyeballs: If the intraocular pressure is still high after glaucoma surgery, you can choose to massage the eyeballs correctly to check whether the function of the filtration vesicles is normal or not, in order to reduce the intraocular pressure. 2. Follicular detachment surgery: If the filtration vesicles are flat indicating poor function, patients need to take the filtration vesicle detachment surgery to promote the normal drainage of the filtration vesicles, thus lowering the intraocular pressure. 3. Medication: If the intraocular pressure is still high after glaucoma surgery, medication such as brinzolamide eye drops can be used to lower the intraocular pressure as prescribed by the doctor. 4. Re-operation: If the intraocular pressure is still high after glaucoma surgery with the above treatments, the patient can undergo surgery again three months after the surgery, such as trabeculectomy. It is recommended that postoperative glaucoma patients follow the doctor’s instructions for care, regular checkups, and timely consultation when discomfort occurs.
