[The diagnoses and treatment of traumatic retinal detachment]
1Zhongsan Ophthalmic Center, Sun Yat-sen University of Medical Sciences, Guangzhou 510060, China.
Purpose:
The diagnoses and treatments of traumatic retinal detachment (RD) were studied retrospectively in this article.
Methods:
A sequence of 25 eyes of traumatic RD included 12 eyes of contusion, 4 explosion and 9 perforation; PVR (Proliferative vitreoretinopathy) < or = C grade 16 eyes and D grade 9 eyes. The techniques were, one: scleral cryotherapy, silicon band buckling and circling, external drainage, which was mainly used to PVR < or = C cases; two: vitrectomy and silicon oil tamponade, which was mainly used to the cases of perforated PVR-D cases.
Results:
Retinal reattachment rate was 91.67% in technique one and 69.23% in technique two. Improvement of visual acuity showed that partial RD was better than total RD (P < 0.01), PVR < or = C better than PVR-D (P < 0.05) and non-perforated better than perforated (P < 0.05).
Conclusion:
The patient who had a history and visual symptoms after an eye injury must be carefully examined by dilating pupil in order that the RD could be early inquired and treated. The techniques one and two must be performed in the severe perforated cases.
