Objective To investigate the clinical characteristics of retinal degeneration (RD) with retinal holes and the therapeutic effect of argon laser therapy. Methods The data of argon laser therapy in 210 RD patients (224 eyes) with retinal holes who underwent the treatment in our department were retrospectively analyzed, which was compared with the data of argon laser therapy in 173 RD patients (198 eyes) without retinal holes. Results In RD patients with retinal holes, 89.7% of the patients were less than 60 years old (53.3% males and 46.7% females). Grid-like degeneration was found in 65.6% of the patients in whom 87.5% had the range of degeneration less than 1 quardrant. There were oval-shaped holes in 60.7% of the patients and accompanied with limited rhegmatogenous retinal detachment (LRRD) in 23.7%. Compared with RD patients without retinal holes, the ratio of patients with the age of≥35 years, cystic degeneration, retinal lengthways small plica, and subjective symptoms was higher in RD patients with retinal holes; while the therapeutic effect of argon laser therapy on patients with LRRD was obviously less than whom without retinal holes (P

Objective To explore the clinical efficacy of artificial blood vessel sheath around re-nal vein for the treatment of left renal vein entrapment syndrome. Methods Eight cases with left re-nal vein entrapment syndrome (7 males and 1 female, mean age, 16 years) with history of gross hema-turia for 6 to 36 months were reviewed. Doppler ultrasound reports suggested compression of the left renal vein at mesenteric angle in all eases. CT scan showed the abnormal angle between aorta and su-perior mesenterie artery in 5 cases. Cystscopy showed hematuria from the left ureteral orifice in 5 ca-ses. All cases with left renal vein entrapment syndrome were treated ,with the method of putting artifi-cial blood vessel as a sheath around left renal vein. Results The operations were all successful. The average operation time was 150 min, the average blood loss was 50 ml, and the average hospital stay after operation was 9 d. No surgical complications occurred. The gross hcmaturia disappeared in 6 ca-ses and Doppler ultrasound showed that left renal vein outflow was normal in 7 when the patients dis-charged from the hospital. The gross hematuria disappeared during 2-24 months' follow-up in 7 pa-tients. Conclusions The surgical aim of renal vein entrapment syndrome is to reduce the compres-sion of renal vein. The method of putting artificial blood vessel around renal vein could be a simple, safe and effective method.
