The cause of low IOP should be searched for and treated accordingly to improve the IOP. 1. Rupture injury of the eye. When the eye is ruptured, it can lead to low IOP, so the location of the ruptured eye should be carefully searched and tightly sutured. 2. Ciliary body detachment. When trauma leads to ciliary body detachment, it can lead to low IOP, which requires anti-inflammatory treatment, such as tobramycin dexamethasone drops, one drop four times a day, and ciliary body suture repositioning if necessary.3. Low IOP after glaucoma surgery. The cause of low IOP should be searched for, such as filter bubble leakage, which should be repaired, and choroidal detachment, which should be treated with anti-inflammatory therapy to eliminate choroidal detachment.
