Timing and skills of treatment for acute symptomatic horse-shoe retinal tears

Abstract

Objective To observe the clinical effects of preventive treatment for acute symptomatichorse-shoe retinal tears.The suitable opportunity and the skill were discussed.Method Ninty-two cases (92eyes)suffered acute symptomatic horse-shoe retinal tears accepts the preventive treatment,the clinical effectwere analyzed retrospectively.The results of the different disease course,treatment method and techniques werecompared.Results (1)Ninty-two cases (92 eyes)accept the preventive treatment, in which 79 cases (85.87%)sealed the tear successfully.Laser photocoagulation for 70 cases,58 cases (82.86%)succeed.Trans-scleralcryotherapy for 22 cases, 21 cases (95.45%)succeed.Cryotherapy is superior to photocoagulation for preventtreat the horse-shoe tear. (x2=98.8,P <0.001). (2)Altogether 13 cases (14.13%)developed into retinaldetachment after treatment.Among them 8 cases (61.54%)happened in 2～5 days,the latest is 42 days.(3)In 12cases who failed with photocoagulation, the disease course of 9 cases (75%)were less than 1 week, the otherswere 3～6 weeks. (4)In 36 cases whose tear formed within 1 weeks, 21 cases accept photocoagulation in routineway(the tears surrounded by densely laser spot for one time ), 8( 38.1% )of them retinal detached.Fifteen casesaccept photocoagulation in different way(large and sparse laser spot,posterior edge were sealed firstly,anterioredge were sealed after 3～5 days), only 1 cases (6.67%)of them formed retinal detachment.Conclusion Acutesymptomatic horse-shoe tears was easy to induced retinal detachment.Following the individuation principle oftreatment can improve the preventive effects.
