增生性糖尿病视网膜病变玻璃体切除硅油或全氟丙烷填充术

目的观察增生性糖尿病视网膜病变（PDR）玻璃体切除术后填充硅油或C3F8的临床效果。方法对本科2010年6月至2011年12月,PDR60例（77眼）行玻璃体切除手术。分硅油填充组和C3F8填充组,两组患者年龄、性别、病程的差异均无统计学意义（P〉0．05）。术后随访视力、眼压、视网膜、视神经变化。结果硅油填充组手术前后视力进行比较,差异有统计学意义（x^2=10．31,P〈0．05）,C3F8填充组手术前后视力进行比较,差异有统计学意义（x^2=9．20,P〈0．05）。两组间手术后视力进行比较差异有统计学意义（x^2=9．01,P〈0．05）。硅油组与C3F8组术后眼压进行比较差异有统计学意义（Z=-3．50,P〈0．05）。硅油组41眼中视盘颜色苍白5眼（12．20％）,视盘色淡3眼（7．32％）,视网膜局部血管闭塞10眼（24．39％）;未发现视网膜再出血或脱离。C3F8填充组36眼术后气体全部吸收,视盘色淡3眼（8．33％）,未发现有视盘色苍白或视网膜局部血管闭塞,视网膜再次出血5眼（13．88％）,视网膜再次脱离2眼（5．55％）。结论PDR行玻璃体切除硅油填充术后效果良好,只有少数患者出现眼压难以控制,最终导致视功能损害。C3F8填充术后没有出现视网膜脱离及再出血者的视功能恢复要好于硅油填充组。所以PDR行玻璃体切除手术后应根据视网膜情况选择合适的玻璃体填充物,填充硅油的患者应在视网膜复位后尽早的取出眼内硅油,避免对视神经、视网膜造成不可逆性损害。     

玻璃体切除联合白内障手术治疗增生性糖尿病视网膜病变的临床效果

目的观察玻璃体切除硅油填充术联合超声乳化白内障摘除人工晶状体植入术治疗增生性糖尿病视网膜病变的临床疗效。方法根据患者自愿原则,将53例（57只眼）增生性糖尿病视网膜病变Ⅵ期患者分成联合手术组和玻璃体手术组。联合手术组33例（33只眼）,单纯玻璃体手术组20例（24只眼）。联合手术组进行玻璃体视网膜手术、硅油填充、超声乳化白内障摘除及折叠型人工晶状体植入术,单纯玻璃体手术组进行玻璃体视网膜手术及硅油填充。对两组术后视网膜复位情况和并发症进行对照分析。结果联合手术组视网膜完全复位29只眼,视网膜复位率为87．9％;单纯玻璃体手术组视网膜完全复位20只眼,视网膜复位率为83．3％,两组比较差异无统计学意义（P=0．626）。联合手术组发生虹膜新生血管1只眼（3．0％）,单纯玻璃体手术组发生虹膜新生血管2只眼（8．3％）。均发生在视网膜未复位的患者,两组比较差异无统计学意义（P=0．775）。结论玻璃体视网膜手术联合超声乳化白内障摘除人工晶状体植入术治疗增生性糖尿病视网膜病变安全有效,联合手术可避免再次行白内障手术。

Rhegmatogenous retinal detachments in children: risk factors and surgical outcomes

PURPOSE: To describe the presenting features and surgical outcomes in a series of children with rhegmatogenous retinal detachments. DESIGN: Retrospective, noncomparative, interventional case series. PARTICIPANTS: Thirty-nine eyes of 34 children 18 years of age or younger undergoing surgery for rhegmatogenous retinal detachment. METHODS: Patients were identified by chart review at two affiliated tertiary care centers. Risk factors for retinal detachment were classified into four categories: (1). congenital or developmental structural ocular abnormalities, (2). trauma, (3). previous ophthalmologic surgery, and (4). preceding uveitis. RESULTS: Median age was 10 years, and 79% of patients were boys. Nine patients (26%) had bilateral retinal detachment at presentation, or experienced a detachment in their second eye before their nineteenth birthday. Every eye had at least one risk factor for retinal detachment, and more than half had risk factors in two or more categories. Structural abnormalities were most common (56%). Fifty-one percent of eyes underwent previous surgery, 36% experienced trauma, and 15% had uveitis. Detachments tended to be complex. Median follow-up was 24 months. Retinal reattachment was achieved in 79% of eyes; however, visual recovery was modest. Median preoperative and postoperative visual acuities were counting fingers and 20/400, respectively. Predictors of a poor visual outcome were: unmeasurable or light perception-only preoperative vision (P = 0.0001), macula-off retinal detachment (P = 0.01), the need for vitrectomy surgery (P = 0.01), the presence of proliferative vitreoretinopathy grade C or worse (P = 0.02), and the use of silicone oil (P = 0.02). CONCLUSIONS: Predisposing factors in pediatric retinal detachments, particularly congenital and developmental structural abnormalities, may be more common than previously reported. Modern vitreoretinal surgical techniques can help achieve retinal reattachment in most cases. Many factors contribute to the limited visual recovery in this patient population. Predictors of visual outcomes are similar to those observed in adults. Inability of the clinician to determine confidently the preoperative visual acuity is a newly identified predictor of poor visual outcomes.     

Pediatric rhegmatogenous retinal detachment: clinical features and surgical outcomes

OBJECTIVE: To describe the characteristics of and surgical outcomes for primary pediatric rhegmatogenous retinal detachment (RRD) and to evaluate whether specific characteristics impact anatomical outcomes after surgical intervention. METHODS: Data for consecutive patients (18 years of age or younger) with RRD who required surgery over a 5-year period were studied retrospectively. Patients with recurrent retinal detachment or active retinopathy of prematurity were excluded. RESULTS: Forty-six eyes of 45 patients (median age, 9 years) were included. Ninety-eight percent of the patients had at least 1 predisposing factor, including prior surgery (61%), trauma (43%), developmental abnormality (35%), and myopia (17%). Retinal reattachment was attained in 78% of eyes. Younger age (P = 0.019), worse initial vision (P = 0.008), greater extent of retinal detachment (P = 0.007), and presence of proliferative vitreoretinopathy (grade C or worse) (P = 0.008) were associated with worse anatomical outcomes. Vision improved after surgery in 56% of patients, but overall visual results were modest. Thirty-seven percent of patients had vision-threatening lesions in the other eye, and 18% had a history of retinal detachment in the fellow eye. CONCLUSIONS: Pediatric RRD is often associated with a predisposing factor. Favorable anatomical and visual outcomes are possible, and lesions in the fellow eye are common.     

影响巩膜扣带术视网膜复位及视力恢复因素的临床观察

目的 探讨巩膜扣带术(scleral buckling,SB)治疗孔源性视网膜脱离(rhegmatogenous retinal detachment,RRD)的疗效以及影响视网膜解剖复位和视力恢复的相关危险因素.方法 回顾性分析2005年1月至2008年12月行sB的RRD患者72例(72只眼).术后随访6-30月,平均(13.96±8.28)月,观察术后视网膜解剖复位率、最佳矫正视力(best corrected visual acuity,BCVA)及并发症.Logistic回归用于分析影响视网膜解剖复位和视力恢复的相关危险因素.结果 在眼底镜和B超检测下视网膜首次复位率为90.28%,最终复位率为97.22%;而光学相干断层扫描(optical coherence tomography,OCT)检测下的视网膜首次复位率为59.72%,最终复位率为77.78%.术后BCVAI>0.3者为62.5%.C1级PVR和多发性裂孔对视网膜复位率有显著影响(P=0.0183、0.0181 ).术前视力、黄斑脱离与否、黄斑脱离时间及PVR的程度对术后视力恢复的影响有统计学意义(P=0.0235、0.0124、0.0325、0.0357). 术后出现葡萄膜炎占13.89%,视物变形占9.72%,增殖性玻璃体视网膜病变(proliferative vitreous retinopathy,PVR)进展占6.94%,黄斑皱褶占6.94%,高眼压占4.17%,复视占2.78%.术后前房深度、眼轴长度、屈光度和散光度的变化较术前差异有统计学意义(P=0.0260、<0.0001、0.0005、0.0018).结论 SB治疗RRD有良好的疗效,但C1级PVR和多发性裂孔会显著增加手术失败的风险.术前视力、黄斑脱离状态和脱离时间及PVR的程度是影响术后视力恢复的重要因素;同时,该手术可导致术后前房深度变浅、眼轴延长、屈光度和散光度向负值偏移.     

Clinical characteristics and surgical outcomes of pediatric rhegmatogenous retinal detachment in Taiwan

PURPOSE: To evaluate the clinical features and surgical and visual outcomes of rhegmatogenous retinal detachment (RRD) in the pediatric population. DESIGN: Retrospective, noncomparative, interventional case series. METHODS: A review of patients under 18 years who underwent primary retinal detachment surgery at National Taiwan University Hospital from 1989 to 2003 was conducted. RESULTS: Included in the study were 152 eyes of 146 patients (mean age of 13.1 years). Male patients comprised 69.9% of the sample. Bilateral RRD was present in 4.1%. Etiologies included myopia >4 diopters (37.5%), trauma (32.9%), developmental anomaly (11.8%), previous surgery (5.9%), previous uveitis (3.9%), atopic dermatitis (2.6%), and unknown (5.3%). Macular detachment was found in 73.0%. The most common primary treatment was scleral buckling (61.2%). Single-operation reattachment was accomplished in 58.5% of patients and eventual reattachment in 78.3% of patients occurring in a mean of 1.5 (SD = 0.9) operations. Average postoperative follow-up time was 48.3 months. Visual improvement occurred in 42.8%, remained the same in 32.2%, and worsened in 19.1%. In the logistic regression model, statistically significant risk factors for poor surgical outcome were nonmyopic RRD (P = .026), macular involvement (P = .01), and presence of proliferative vitreoretinopathy (P = .07). CONCLUSIONS: Myopia >4 diopters was the most common etiology in retinal detachment in our sample, followed by trauma. Myopia (> -4.0 diopters) may be more common than previously reported. Most eyes (78.3%) were anatomically reattached after multiple surgeries. Retinal detachment not associated with myopia is a newly identified predictor for poor surgical outcomes.     

Characteristics and surgical outcomes of paediatric retinal detachment

PURPOSE: To report the clinical features and surgical and visual outcomes of rhegmatogenous retinal detachment (RRD) in the paediatric population. METHODS: A retrospective review of children (aged 0-15 years) who underwent primary surgical repair for RRD at the Hiroshima University Hospital between 1988 and 2001. RESULTS: In all 53 eyes of 49 patients were identified; paediatric RRD accounted for 3.1% of 1779 eyes with RRD operated on during this period. The causes of RRD included blunt trauma (27%), myopia (25%), idiopathic (20%), familial exudative vitreoretinopathy (13%), and others. Among 55 eyes, 12 (22%) already had proliferative vitreoretinopathy (PVR) of grade C or D preoperatively. The median initial visual acuity (VA) was 0.3. Retinal reattachment was achieved with a single operation in 78%. Final retinal reattachment was achieved in 87%. Retinal reattachment rates with and without PVR were 42% and 100%, respectively (P<0.01). Median final VA was 0.7. Final VA was > or =0.1 in 73% and > or =0.5 in 53%; four eyes had a final VA of no light perception. The presence of preoperative PVR (P=0.03) and the initial VA (P<0.0001) significantly affected final VA. CONCLUSIONS: Paediatric RRD is characterised by a delay in diagnosis, as evidenced by the high rate of PVR at presentation. Retinal reattachment was adversely affected by the presence of PVR. Final VA correlated with the initial VA and was significantly affected by preoperative PVR. Early diagnosis may improve the visual prognosis of paediatric retinal detachment.     

玻璃体切除术治疗合并脉络膜脱离的孔源性视网膜脱离

目的探讨玻璃体切除术治疗合并脉络膜脱离的孔源性视网膜脱离的临床疗效。方法对连续治疗的12例(12只眼)合并有脉络膜脱离的孔源性视网膜脱离眼,进行玻璃体切除联合长效气体或硅油填充治疗,所有患者术前、术后均用激素治疗,对视网膜的复位率进行评价。结果术后平均随访10.42个月。单次手术视网膜解剖复位率为91.67%(11/12),再次手术后视网膜解剖复位率为100%。结论玻璃体切除术是治疗合并脉络膜脱离的孔源性视网膜脱离的有效方法。     

Pediatric rhegmatogenous retinal detachment

PURPOSE: To review the clinical features and surgical and visual outcomes of pediatric rhegmatogenous retinal detachment (RRD) as seen in a tertiary referral center. METHODS: Retrospective case series spanning 6 years from January 1, 1991 to January 1, 1997. Exclusionary criteria were trauma disrupting the globe and acute retinopathy of prematurity. RESULTS: The authors reviewed a series of 29 eyes in 27 pediatric patients (birth to 18 years of age) with RRD. Seventy percent of the patients were male. The mean patient age was 9.6 years. Bilateral RRD was present in 22% of patients; 89% of patients had some form of bilateral ocular pathology at initial presentation. The two most common etiologies (34% each) were myopia and eyes that had undergone surgery for another ocular disorder with subsequent development of RRD. The most common presentation was decreased vision, with a mean duration of 52 days. At presentation, 75% of the affected eyes and 48% of the fellow eyes had visual acuity worse than 20/800. The most common type of retinal break was a horseshoe tear. Late diagnosis was a common problem, evidenced by the frequency of macular detachment (79%) and proliferative vitreoretinopathy (45%) at initial presentation. The most common primary repair was a scleral buckle. Anatomic reattachment was ultimately accomplished in 72% of cases with a mean of 2.2 surgeries per eye. Average postoperative follow-up time was 21.4 months (range 4 to 61 months). At final follow-up, 41% of the affected eyes had visual acuity 20/800 or better. Thirty-eight percent of the affected eyes had a final visual acuity better than or equal to the fellow eye. CONCLUSION: In this series, pediatric RRD occurred most commonly in association with myopia (Stickler's syndrome and adolescent retinopathy of prematurity) and prior intraocular surgery. Most eyes were anatomically reattached after multiple surgeries. Forty-one percent of eyes retained vision of 20/800 or better. Preserving vision in children with RRD is of great importance, particularly given the 89% frequency of vision-threatening abnormalities in fellow eyes.     

Management of recurrent retinal detachment in silicone oil-filled eyes

PURPOSE: To report causes of failure, management options, and outcomes after reoperations for recurrent retinal detachment in silicone oil-filled eyes. METHODS: One hundred eighteen silicone oil-filled eyes with recurrent retinal detachment were managed with revision of vitrectomy with membrane surgery with or without silicone oil removal, just scleral buckling, or both. Anatomical success was defined as complete reattachment of the retina, and functional success was defined as recovery of ambulatory visual acuity of >or=5/200 at the last follow-up (mean follow-up, 29.7 months). RESULTS: In 82.2% of the cases, proliferative vitreoretinopathy was responsible for recurrent retinal detachment in silicone oil-filled eyes. Reoperations without removal of the silicone oil were performed in 65.3% of the cases. Anatomical success occurred in 62.7% of the eyes, and functional success occurred in 52.5%. Silicone oil was removed in 59.5% of the eyes with retinal reattachment; the retina remained attached in 90.9% of the eyes. Predictors of poor anatomical success were presence of posterior diffuse proliferative vitreoretinopathy and combined posterior and anterior proliferative vitreoretinopathy (P <0.02). CONCLUSION: Reoperations for recurrent retinal detachment in silicone oil-filled eyes were successful in nearly two thirds of the cases, and over one half of the eyes recovered ambulatory vision.     

Primary repair of retinal detachment with 25-gauge pars plana vitrectomy

PURPOSE: To evaluate 25-gauge pars plana vitrectomy (PPV) for primary repair of rhegmatogenous retinal detachment (RRD). STUDY DESIGN AND PARTICIPANTS: This retrospective, consecutive case series included 42 eyes of 41 patients who underwent primary repair of RRD utilizing transconjunctival 25-gauge PPV without scleral buckling at the Cincinnati Eye Institute from July 2004 through January 2007. METHODS: The medical records were retrospectively reviewed, and the corresponding demographic data, preoperative ophthalmic diagnoses, surgical management, and postoperative course and treatment were recorded. Main outcome measures included single surgery anatomical success, preoperative and postoperative visual acuity, and complications. RESULTS: Most patients had pseudophakic RRD (36 [85.7%] of 42 eyes). The crystalline lens was present in the remaining 6 eyes (14.3%). Of 42 eyes, 28 (66.7%) had macula-on RRD, while 14 (33.3%) had macula-off RRD. Four surgeons contributed to this study, and 25-gauge PPV instrumentation, a wide-angle viewing system, endolaser photocoagulation, and gas tamponade were used in each case. The single surgery anatomical success rate was 92.9% (39 of 42 eyes). For eyes with macula-on RRD, best-corrected visual acuity was 20/50 (0.43 logMAR [logarithm of the minimum angle of resolution]) preoperatively and 20/30 (0.23 logMAR) postoperatively (P = 0.24). For eyes with macula-off RRD, best-corrected visual acuity was 5/200 (1.56 logMAR) preoperatively and 20/30 (0.23 logMAR) postoperatively (P = 0.001). Three eyes required additional surgery for final reattachment. Final reattachment was achieved in 100% of patients (mean follow-up, 8 months). CONCLUSIONS: Twenty-five-gauge PPV with laser retinopexy and gas tamponade is effective for primary repair of RRD. The single operation anatomical success rate is comparable with rates reported for primary vitrectomy with 20-gauge instrumentation, scleral buckling, and combined vitrectomy/scleral buckling.
