Generally speaking, high intraocular pressure after retinal surgery may be caused by inflammatory reaction, abnormal reaction to silicone oil, intracranial tumor compression, etc. Symptoms can be improved through medication and surgery. 1. Drug treatment: After retinal detachment surgery, patients may have elevated intraocular pressure due to inflammatory reaction induced by unclean personal hygiene, resulting in increased resistance to aqueous drainage. You can reduce intraocular pressure through medication, such as intravenous 20% mannitol, oral vinpocetine tablets, or eye drops to reduce intraocular pressure, such as timolol maleate eye drops. High intraocular pressure may also occur after surgery when retinal detachment surgery is performed and in the case of compression by an intracranial tumor, which tends to put pressure on the optic nerve. It is usually treated with drugs such as dexamethasone, phenytoin sodium and carbamazepine. 2. Surgical treatment: When patients undergo retinal detachment surgery, doctors may inject silicone oil into the patient’s eyes for the surgery. If the silicone oil is not taken out in time, it will cause emulsification of silicone oil in the eyes, which will increase the intraocular pressure. Anterior chamber puncture to release the aqueous humor can be used to lower the intraocular pressure. When the symptoms of intracranial tumor compression are more serious, the IOP can be lowered by radical tumor surgery and posterior cranial fossa decompression. In addition, it is recommended that high intraocular pressure after retinal surgery should go to the hospital in time to avoid delaying the condition, and follow the doctor’s instructions for medication and surgical treatment.
