Postoperative intraocular pressure of 26 mm Hg after glaucoma surgery is considered high intraocular pressure, which generally needs to be dealt with, and the patient can be treated medically or surgically to control the intraocular pressure, but the specific treatment is related to the patient’s condition. The normal value of intraocular pressure (IOP) is 11 to 21 mmHg. If IOP exceeds 21 mmHg, it can generally be characterized as pathologically elevated IOP, which is a major risk factor for glaucoma and can impair a patient’s vision. After glaucoma surgery, the patient’s intraocular pressure is 26 mmHg, which may be caused by inflammation in the early stage, and the patient can use anti-inflammatory eye drops and intraocular pressure-lowering eye drops as prescribed by the doctor, such as tobramycin eye drops, brinzolamide eye drops, etc. If the effect of medication is not satisfactory, the patient may be treated with anti-inflammatory eye drops and intraocular pressure lowering eye drops. If medication is not effective and the patient’s intraocular pressure increases persistently, secondary surgery should be considered to reduce intraocular pressure and avoid further visual impairment. It is recommended that patients after glaucoma surgery follow the doctor’s instructions for care, regular review, and timely consultation when discomfort occurs.
