Patient: Hello, my grandmother is blind due to glaucoma in one eye, and she can only see blurred shadows in the other eye after surgery, but her eye pressure is still high. I need your answer urgently, thank you! Glaucoma Department, Beijing Tongren Hospital: Hello! The patient’s IOP is still high after glaucoma surgery and needs to continue treatment. First of all, the IOP should be controlled, and if the IOP cannot be controlled normally with medication, surgery is also needed to get the IOP under good control. Controlling IOP is crucial for patients with glaucoma. Whether or not vision improves after surgery depends on the individual case. Due to the patient’s age, it is likely that cataracts are present in combination. If the cataract is heavy and the glaucomatous optic nerve damage is light, the visual function is expected to improve after surgery. If the cataract is mild and the fundus damage is heavy, the visual function will not be easily improved. If you have the condition, you can come to our hospital for examination, including slit lamp examination, intraocular pressure examination, visual function examination, fundus stereophotography, laser vision, etc., to make a comprehensive assessment before reaching a conclusion.
