视网膜脱离术后可能发生浆液性脉胳膜脱离,1966年Hawking等报导其发生率为23％,并指出其发生与病人年令、涡静脉损伤与否、透热程度和引流视网膜下液有关。引流视网膜下液必将产生一过性低眼压,一经填充、缝合、结扎眼压很快恢复。浆液性脉胳膜脱离可能就在这一过性低眼压阶段发生。白内障手术切开眼球时也产生一过性低眼压,这与引流视网膜下液过程相似。白内障术后低眼压常伴有脉胳膜脱离已为眼科学者熟知。1935年O′Brien用单眼直接检眼镜观察,发现25例白内障术后立即发生脉胳膜脱离。
Serous detachment may occur after retinal detachment surgery. In 1966, Hawking et al. Reported a rate of 23%. It was also reported that the occurrence of retinal detachment was related to patient year, vortex vein injury, degree of diathermy and drainage of subretinal fluid. Draining subretinal fluid will have a transient low intraocular pressure, once filled, suture, ligation intraocular pressure quickly restored. Serous dissection may occur at this stage of transient hypotony. Cataracts also produce transient hypotony when the eye is opened, similar to drainage of the subretinal fluid. Hypotension after cataract surgery is often associated with dissection of the venous arteries well known to ophthalmologists. In 1935 O’Brien with monocular direct ophthalmoscope observation and found that 25 cases of cataract immediately after the occurrence of retinal detachment.
