Severe ocular rupture may be accompanied by suprachoroidal hemorrhage, or subretinal hemorrhage, or with suprachoroidal hemorrhage and subretinal hemorrhage. The suprachoroidal hemorrhage needs to be drained as soon as possible. In the process of waiting for the spontaneous liquefaction of hemorrhage, uncontrollable elevated intraocular pressure may occur, resulting in optic nerve injury, optic nerve atrophy, and visual loss. Tissue plasminogen activator can promote the liquefaction of blood clots. Studies have found that local application of tissue plasminogen activator in the suprachoroidal space can promote the liquefaction of the hemorrhage. Local application of tissue fibrinogen activator under the retina can promote the liquefaction of subretinal hemorrhage.

Severe ocular rupture may be accompanied by suprachoroidal hemorrhage, or subretinal hemorrhage, or with suprachoroidal hemorrhage and subretinal hemorrhage. The suprachoroidal hemorrhage needs to be drained as soon as possible. The traditional treatment method needs to wait for the spontaneous liquefaction of the suprachoroidal hemorrhage, and then perform scleral incision to drain the liquefied suprachoroidal hemorrhage. However, in the process of waiting for the spontaneous liquefaction of suprachoroidal hemorrhage, uncontrollable elevated intraocular pressure may occur, resulting in optic nerve injury, optic nerve atrophy, and visual loss. In addition, if the suprachoroidal hemorrhage is not completely liquefied, it will not be completely drained, which will lead to choroidal function damage, low intraocular pressure and eyeball atrophy.

Severe ocular rupture can be accompanied by a large amount of subretinal hemorrhage. The traditional treatment is to open the retina in a large area and drain the subretinal hemorrhage. However, extensive retinal incision has great damage, vitreoretinal proliferation often occurs after surgery, leading to recurrent retinal detachment, large area of choroid exposure, low intraocular pressure, and atrophy of the eye.

Tissue plasminogen activator can promote the liquefaction of blood clots. Studies have found that local application of tissue plasminogen activator in the suprachoroidal space can promote the liquefaction of the hemorrhage near the suprachoroidal space, and can drain the hemorrhage of the suprachoroidal space smoothly and completely in the early stage. Local application of tissue plasminogen activator under the retina can promote the liquefaction of subretinal hemorrhage. Through small retinal incision, subretinal hemorrhage can be completely drained, the scope of retinal incision can be reduced, vitreoretinal proliferation can be reduced, and the occurrence of recurrent retinal detachment after surgery can be reduced.
