    摘要: Injection of silicon oil (SO) to the anterior chamber of an eye efficiently induces intraocular pressure (TOP) elevation. This effect occurs without causing overt ocular structural damage or inflammatory responses while simulating acute glaucomatous changes that human patients develop over years by inducing progressive RGC and ON degeneration and visual functional deficits within weeks. The anterior segments of the experimental eyes are not substantially affected, leaving clear ocular elements that allow easy and reliable assessment of in vivo visual function and morphology. More importantly, this is the only reversible ocular hypertension model by removing SO from the anterior chamber and particularly useful for testing neuroprotection treatment together with lowering TOP treatment. In summary, the acute ocular hypertension glaucoma model replicates secondary post-operative glaucoma. It is straightforward and reversible, does not require special equipment or repeat injections, and may be applicable to a range of animal species with only minor modifications.
