To investigate the clinical efficacy of minimally invasive 23G vitrectomy combined with chandelier for the treatment of superior bullous rhegmatogenous retinal detachment (SBRRD).A retrospective case series study of 50 patients with SBRRD was conducted. Each of these patients received minimally invasive 23G vitrectomy in one of their eye. A trocar was indwelled with two-step 23-G incision, and the chandelier was inserted in the inferior 6 o'clock pars plana. The tear was closed with 23-G vitrectomy combined with endolaser photocoagulation and infused with perfluoropropane (C3F8) under non-contact wide-angle lens. Postoperative follow-up ranged from 5-49 months (mean 23.9±1.3 months). Intraoperative and postoperative complications, postoperative conjunctival hyperemia, eye irritation signs and inflammation reactions, retinal anatomic reduction rate, best corrected visual acuity (BCVA) and intraocular pressure (IOP) changes were analyzed.The intraoperative scleral incision leakage required 17 sutures (34%). No complications, such as iatrogenic retinal breaks and hemorrhage occurred. The postoperative conjunctival hyperemia, eye irritation signs and inflammation reactions were mild. Transient low IOP occurred in one eye (2%) on the first day postoperatively and recovered on the next day. Transient low IOP occurred in eyes of 16 subjects (32%) and recovered after lowering IOP therapy within an average of 4 days. No complications, such as hemorrhage, effusion, choroidal detachment and endophthalmitis were observed. Forty-nine subjects (98%) had retinal reattachment in their eyes after a single surgery, and 100% eyes showed final retinal reattachment. The preoperative and postoperative BCVAs were 4.61±0.19 and 4.70±0.19, respectively, in 8 patients without detached macula, and the difference was not statistically significant (t = 2.20, p0.05).Minimally invasive 23G vitrectomy combined with chandelier is a safe and effective surgical approach for the treatment of SBRRD.

To determine the curative effect and complications of 23G vitrectomy via corneal approach for the treatment of pediatric cataract.We performed anterior circular capsulotomy, lentectomy and aspiration, posterior circular capsulotomy, and anterior vitrectomy via corneal approach in 40 eyes from 25 children with congenital cataract. In patients aged2 years, foldable intraocular lens (IOL) was implanted and frame glasses were prescribed at younger age. The intraoperative/postoperative complications, comfort level, and inflammatory reaction after surgery were observed.No intraoperative complications occurred and 9 eyes were simultaneously implanted IOL. All patients could blink normally except one child who suffered from corneal epithelial abrasion for one day. All corneas were clear and only mild postoperative inflammation was observed. There was no hyphema, effusion, hypotony, and hypertension. A week later, the mild congestion also disappeared. All parents reported good vision of their babies allowing them free play during 3-50 months follow-up. This surgical technique provided a clear 4-6 mm diameter visual axis and circular pupil in all cases. The IOL positions were centered at the pupil area. No secondary cataract developed.The 23-gauge vitrectomy via corneal approach for the treatment of pediatric cataract involves only mild discomfort and fewer complications.

A total of 54 cases (73 hips) with ischemic necrosis of the femoral head after treatment of CDH have been followed up with an average of 7 years. We found that 89% cases of type I and 70% of type II recovered to normal and 83% cases of type III and IV developed the coxa breva deformity due to injury of longitudinal growth plate of the proximal end of the femur. According to the value of ATD, the coxa breva was divided into three types. The L shape growth disturbance line revealed by X-ray is considered as a marker for determination of early epiphyseal plate injury by the authors.

Intramedullary pressure in the proximal femur was measured before and after treatment of congenital dislocation of the hip. The intramedullary pressure before treatment was higher than that of the control group, and after treatment it was lower as a whole; in the close reduction group the pressure decreased as compared with the operation group. In 8 hips, stress test yielded negative results. These findings suggested the characteristics of arterial blockage may be that the potential cause of avascular necrosis of the femoral head after treatment of congenital dislocation of the hip.
