  • Clinical characteristics and therapeutic effect of retinal detachment in aphakic and pseudophakic eyes in 805 patients

    Objective To observe the clinical characteristics and therapeutic effect of aphakic retinal detachment (ARD) eyes and pseudophakic retinal detachment (PPRD) eyes.Methods  The clinical data of 805 patients,including 321 ARD and 484 PPRD eyes were retrospectively analyzed.The patientsprime;visiual acuity, refraction, intraocular pressure were examined, and the patients also underwent slit lamp microscopy and direct and (or) indirect ophthalmoscopy.The preoperative bestcorrected visual acuity (BCVA) was between light perception (LP) and 0.6.Mainly according to the PVR grade and retinal holes position to take the scleral buckling or vitrectomy combined with scleral buckling. The 805 eyes were divided into 1995-1999 group (243 eyes) and 20002007 group (562 eyes) according to operative time.The follow-up ranged from 3 to 25 months, with an average of 12.3 months.The success standard of surgery was set as anatomic retinal reattachment and the last follow-up time was considered as the judgment time.The surgical complications were recorded at each followup time points. The composition of PPRD,the visual acuity,ocular lesions, surgical methods and results before operation and visual acuity after operation in two groups were analyzed and compared by MantelHaenszel chisquare test. Results The average interval from lens extraction to RD occurrence was 15.4 months in PPRD eyes and 39.1 months in ARD eyes. The final total anatomic success rate was 95.9%, and was 93.5% in the scleral buckle eyes and 97.2% in vitrectomy eyes.The BCVA was better than 0.3 after operation only in 11.9% of the 805 patiens,and the visual acuity increased more than 2 lines in 67.3%. Compared with the ARD eyes,early onset, high proportion of total posterior vitreous detachment,severe PVR,wide RD range,low detection rate of retinal hole and low antomic success rate were found in PPRD eyes.Compared with the 1995-1999 group,the proportion of vitreous surgery,anatomic success rate and better visual acuity were found in 2000-2007 group.Conclusions  The ocular lesions of ARD and PPRD is more complicated,the therapeutic effect are improving in recent years.

  • A meta-analysis of uncomplicated retinal detachment surgery after cataract surgery

    Objective To compare the efficacy and safety of pars plana vitrectomy (PPV) versus scleral buckling (SB) on rhegmatogenous retinal detachment (RRD) after cataract surgery. Methods A computerized search was conducted in the Cochrane Library, Medline, Embase, China National Knowledge Infrastructure (CNKI), Chinese Biological Medicine Database (CBM) combined with manually searching of related literatures. Randomized controlled trials (RCT) comparing PPV with SB for RRD after cataract surgeries were collected. Best corrected visual acuity (BVCA), reattachment rate after primary surgery, final reattachment rate and complications between the two operations were compared. Results A total of four RCTs were included in this meta analysis, including 690 eyes of 690 patients (331 eyes in the PPV group, 359 eyes in the SB group). There was no difference in reattachment rates after primary surgery between two groups [odds ratio (OR) =1.68; 95% confidence interval (CI), 0.81-3.49; P=0.16). Final reattachment rate were in favor of PPV (OR=1.97; 95% CI,1.04 -3.73;P=0.04). There was no significant difference in the proportion of BCVA at six months (weighted mean difference=0.06; 95%CI,-0.01- 0.14; P=0.11). PPV was associated with a significantly lower frequency of diplopia/extrocular muscle dysfunction than SB (OR=6.59; 95% CI1.16 - 37.27; P=0.03), whereas other complications, such as proliferative vitreoretinopathy, macular pucker, cystoid macular edema, and choroidal detachment did not differ statistically (P>0.05). Conclusion Compared with SB, PPV is more likely to achieve a favorable final reattachment rate for RRD after cataract surgery, and with a lower rate of diplopia/extrocular muscle dysfunction.

  • The changes of optical coherence tomography images of the macula after phacoemul sification in diabetics 

    Objective To investigate the effects of phacoemulsification on macula in diabetics. Methods Thirty eyes of cataract in diabetics were chosen randomly for measurement of the thickness of fovea of retina using OCT before phacoemulsification and 1 month after surgery . The other eyes in these patients and 30 eyes of cataract in nondiabetic pati ents with phacoemulsification were as control. Results In 30 eyes of diabetics with phacoemulsification, the mean fovea thickness were (148.5plusmn;27.7) mu;m preoperatively and (219.4plusmn;68.23) mu;m postoperatively, and the difference was significant (Plt;0.05). In 30 eyes of diabetics without surgery, the mean foveal thickness were (147.4plusmn;27.5) mu;m preoperatively and (148.2plusmn;27.3) mu;m postoperatively and the difference was not significant (Pgt;0.05). In 30 eyes of cataract in nondiabetic patients, the mean fovea thickness were (142.37plusmn;12.7) mu;m preoperatively and (151.9plusmn;23.7) mu;m postoperatively and the difference was not significant (Pgt;0.05). In 30 eyes of diabetic s with phacoemulsification, 11 eyes had new macula edema after surgery and 3 eye s had significant retinal thickening. In 6 eyes with macular edema before surgery, the macular edema were aggravated in 3 eyes after surgery. The macular stru ctural changes were not found in two control groups. Conclusion The thickness of retina is inreased after phacoemulsification in deabetics,and morbidity and its severity of postopevative macular edema are increas ed as well. (Chin J Ocul Fundus Dis, 2001,17:175-177)
