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 bestcorrected 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 20002007 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 followup 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 MantelHaenszel chisquare 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.
Objective To investigate the nature of the suprachoroidal fluid by detecting the concentration of total protein (TP), lactate dehydrogenase (LDH), albumin (ALB), total cholesterol (CHOL), total bilirubin (TBIL) in suprachoroidal liquid of patients who have rhegmatogenous retinal detachment with choroid detachment (RRDCD). Methods Eighteen RRDCD patients (18 eyes) who underwent vitrectomy were enrolled in this study. There were 10 males (10 eyes) and 8 females (8 eyes), 8 right eyes and 10 left eyes. There were 8 patients with age of ≤55 years, 10 patients with age of ＞55 years. There were 7 patients with duration of ≤30 days, 11 patients with duration of ＞30 days. There were 7 eyes with diopters of ≥−6.0 D, 11 eyes with diopters of ＜−6.0 D. There were 11 eyes with class C proliferative vitreoretinopathy (PVR), 7 eyes with class D PVR. Suprachoroidal fluid samples were collected from all the patients, and took preoperative serum samples as RRDCD group. Ten serum samples of normal people were set as control group. The concentration of TP, LDH, ALB, CHOL, TBIL in all the subjects were measured. The properties of the suprachoroidal fluid were identified by Light standard and concentration standard of ALB, CHOL, TBIL. Results There was no difference on the concentration of TP, LDH, ALB, CHOL, TBIL from suprachoroidal fluid samples in the patients with different age, sex, eyes, diopter, PVR grade (P＞0.05). There was no difference on the concentration of TP, LDH, ALB, CHOL, TBIL from preoperative serum samples in the patients between RRDCD group and control group (P＞0.05). There was no difference on the concentration of ALB and CHOL from suprachoroidal fluid samples and preoperative serum samples in the RRDCD patients (P＞0.05), but there were significant differences on the concentration of TP, LDH, TBIL (P＜0.05). According to the Light standard, there were 17 cases of exudates and 1 case of transudate. According to the concentration standard of ALB, CHOL and TBIL, there were 14, 18, and 16 cases of exudates, and 4, 0, and 2 cases of transudate, respectively. There was no difference on the identification result of Light standard and concentration standard of ALB, CHOL, TBIL (χ2=2.090, 1.029, 0.364; P＞0.05). Conclusion The suprachoroidal fluid of RRDCD patients composed of TP, LDH, CHOL and TBIL. The suprachoroidal fluid is more likely to be exudate.
Objective To discuss the treatment of retinal detachment(RD) after posterior chamber intraocular lents(PCIOL) implantation. Methods Twenty eyes with RD after PCIOL inplantation which were treated with vitrectomy combined with scleral buckling and intraocular tamponade from March 1993 to June 1997 in this institute were analysed retrospctively. Results The retinas reattached completely in 16 eyes and partly in 2 eyes after RD operation.The postoperative visual acuity improved in 17 eyes,not improved in 2 eyes,and decreasde in 1 eyes.The PCIOL was taken off during RD operative in 6 eyes.Postoperative complications including displacement of the PCIOL in 2 eyes,hyphema and vitreous hemorrhage were found in this series of RD operation in 1 eyes. Conclusion Vitrectomy combined with scleral buckling and intraocular tamponade is one of the effective methods to treat the eyes with RD with PCIOL. (Chin J Ocul Fundus Dis,1998,14:165-166)
