OBJECTIVE:To investigate the treatment of retinal redetachment after vitrectomy and silicone oil tamponade. METHODS:Investigating retrospectively on the treatment effect of 8 cases of redetachment of retina with proliferative vitreoretinopathy(PVR) in which the retinas had been attached formerly after vetrectomy and silicone oil tamponade operation.The reoperative procedures included pars plana vitrectomy,membranes peeling,retinotomy,inner exchange of the fluid and silicone oil tampnade and subretinal membranes were removed out in 2 eyes. RESULTS:Six eyes had anatomical reattachment postoperatively and another 2 eyes still had inferior shallow retinal detachment.Visual acuity was improved in 6 patients and remained unchange in 2 patients. CONCLUSIONS:The cause of recurrent retinal detachment might be the formation of the proliferative epiretinal and subretinal membranes,and vitrectomy to release the traction of proliferative membranes and full fluid silicone oil exchange should do good to reattachment. （Chin J Ocul Fundus Dis,1996,12: 13-15 ）
ObjectiveUsing retrospective study to analyze the data of 112 patients with benign childhood epilepsy with centrotemporal spikes (BECTS) and investigate the clinical characteristics and provide some clinical experience in treatment. MethodsWe collected the medical records of 112 cases of BECTS children in the First Affiliated Hospital of Guangxi Medical University of children's clinics from January 2011 to December 2012. According to whether taking antiepileptic drugs (AEDs) treatment regularly, the 112 cases with BECTS was divided into the treated group and the non-treated group, then analyzed the clinical characteristics between the two groups retrospectively, including age of onset, single episode duration, frequency of seizure, pattern of seizure and EEG performances. ResultsThrough regular AEDs treatment, the duration of a single attack was shortened, generalized tonic-clonic seizure(GTCS) was decreased significantly in the treatment group (P < 0.05). For patients whose seizure frequency was≥3 times/3 months, AEDs could effectively control or reduce their seizure frequency (P < 0.05), while AEDs had no obvious effect on the seizure frequency of those whose seizure frequency was≤2 times/3 months (P > 0.05). In the treatment group, 29 cases whose age < 7 controlled their epilepsy attacks after taking AEDs for average of 13.76 months, while 35 cases whose age≥7 controlled their epilepsy attacks after taking AEDs for average of 6.36 months. Conclusion①BECTS patients with a long duration of a single attack and seizure frequency more than 3 times/3 months could be effectively controlled after receiving early AEDs treatment.②The younger age of onset (< 7 years old) required longer AEDs treatment to control seizures.
