Ocular trauma is an important cause of blindness among young people. Injuries of the iridocorneal angle cause ocular hypertonia and postcontusive glaucoma. The purpose of this work is to study clinical and therapeutic particularities of postcontusive ocular hypertonia.
This is a retrospective study on 13 patients (12 men and 1 woman) with ocular hypertonia as a result of contusive trauma of the iridocorneal angle, with no hyphema or lens dislocation. Patients were 16 to 38 years old.
Ocular hypertonia appeared between 1 week and 6 months after the trauma. The lesions involved were cyclodialysis (2 cases), angle recession (11 cases) and iridodialysis (2 cases). Ocular hypertonia was complicated in 6 cases by contusive glaucoma (as shown by optic disk examination and visual field exploration). The balancing of intraocular pressure was obtained by local treatment in only 9 cases and by trabeculectomy in 5 cases.
The authors discuss the physiopathology, therapeutic particularities as well as the prognostics of contusive ocular hypertonia by iridocorneal angle damage.
Screening for ocular hypertonia must be regular and systematic after ocular trauma involving lesion of the iridocorneal angle.
眼外伤是年轻人失明的重要原因。虹膜角膜角损伤会导致眼压升高和挫伤性青光眼。本研究旨在探讨挫伤性眼压升高的临床及治疗特点。
本研究为回顾性研究，共纳入13例（12例男性，1例女性）因虹膜角膜角挫伤导致眼压升高的患者，均无前房积血或晶状体脱位。患者年龄在16至38岁之间。
眼压升高出现在外伤后1周内至6个月之间。损伤类型包括睫状体脱离（2例）、房角后退（11例）和虹膜根部离断（2例）。6例患者并发挫伤性青光眼（通过视盘检查和视野检查确诊）。仅9例患者通过局部治疗眼压得到控制，5例患者接受了小梁切除术。
作者讨论了虹膜角膜角损伤导致的挫伤性眼压升高的病理生理、治疗特点及预后。
对于涉及虹膜角膜角损伤的眼外伤患者，必须定期、系统地筛查眼压升高情况。
