[Contusions of the eye, their clinical picture and outcomes]. / Kontuzii glaza, klinicheskaia kartina i iskhody.

Clinical observations of 426 patients with blunt injuries to the eye (records of Moscow Ophthalmological Clinical Hospital) showed that eyeball contusions were responsible for 40.57% of hospital injuries, 364 cases (85.54%) were communal traumas and 22.77% criminal. The most frequent complication of blunt injury to the eye was hemorrhage to the anterior chamber (57.57%). Total or almost total hyphemas were observed in 5.83% cases, in 0.7% with repeated hemorrhages. Hemorrhages into the vitreous body were observed in 36.6% patients. Postcontusion opacities and retinal edemas were diagnosed in 25.87% cases. The most severe contusions of the eyeball with ruptures of fibrous membrane were observed in 19.11% cases, 6.29% of these along the postoperative cicatrix. Subdislocation or dislocation of the lens took place in 13.75% cases. Blunt injury to the eye resulted in alteration of ophthalmic tone presenting as reactive hypertension (22.33%), reactive hypotone (11.19%), secondary hypertension (17.01%), and stable hypotone (5.59%). By discharge from hospital visual functions improved in 72.73%, visual acuity of 0-0.03 diopters was observed in 14.92% and 0.4-1.0 in 63.87% cases. Secondary hypertension persisted in 1.86% and stable hypotone of the injured eye in 5.13% cases.

[Role of kallikrein-kinin system in pathogenesis of eye contusions]. / Rol' kallikrein-kininovoi sistemy v patogeneze kontuzii glaza.

Studies of the plasma components of the kallikrein-kinin system (KKS) in the lacrimal fluid (LF) of damaged eyeball of 32 patients hospitalized for contusion for the eyeball showed an appreciable increase of KKS activity during the first three days and its less expressed increase on days 10-19 after the injury. The content of prekallikrein in the damaged eye LF depends on the severity of eye contusion and plasma KKS status, and the levels of LF prekallikrein in the damaged and intact eye correlate. Serum kallikrein activity depends on the severity of injury.
