玻璃体切割治疗急性视网膜坏死的手术时机及疗效分析

目的探讨玻璃体切割术治疗急性视网膜坏死(Acute retinal necrosis，ARN)的有效性及手术时机选择。方法对11例(11只眼)ARN患眼进行玻璃体切割手术，其中7只眼伴严重玻璃体混浊，2只眼伴局限性视网膜脱离，2只眼视网膜全脱离、多发性裂孔。年龄12岁～55岁，平均34．2岁，手术眼距初发病时间20天至8个月，其中3个月以内者9例。术前视力：手动/10～30cm者2例，指数/20～30cm者2例，0．02～0．08者4例，0．1者3例。诊断明确后即予阿昔洛韦或更昔洛韦及皮质类固醇治疗。然后对严重玻璃体混浊，视网膜炎性渗出范围超过赤道区到达后极部．周边部已发现干性裂孔或有广泛玻璃体视网膜增殖性病变者采用玻璃体切割术，切除混浊之玻璃体，清除增殖及大部分渗出灶，作次全视网膜光凝。11例中8例辅助巩膜外环扎术，6例作晶体切除，10只眼一次性注入硅油填充，另1只眼作气液交换后12d发生视网膜、脉络膜广泛脱离，二次手术注入硅油。结果随访8个月至3年，平均19．3个月。11只眼中9只眼视网膜平伏，2只术前有视网膜脱离眼取硅油术后复发性视网膜脱离，无光感。成功9只眼视力均保持FC/30cm以上的有用视力，其中4只眼视力0．1，3只眼视力0．2。视力≥0．1者占78％。结论对ARN病情发展严重者选择适当时机，即在视网膜脱离发生前，已有严重玻璃体混浊影响眼底观察和激光治疗、周边部已发现干性裂孔或有广泛玻璃体视网膜增殖性病变时应进行玻璃体切割手术，有防止视网膜脱离发生或发展，保持较好有用视力的作用。

Long-term anatomical and visual outcome of vitreous surgery for retinal detachment with choroidal coloboma

CONTEXT: Vitreous surgery has been advocated as an alternative treatment of selected retinal detachments with choroidal colobomas. AIM: To study the long term anatomical and visual outcome of choroidal coloboma with retinal detachment managed by pars plana vitrectomy with silicone oil tamponade. SETTING AND DESIGN: Retrospective study conducted in a tertiary eye care hospital. MATERIALS AND METHODS: Fourty two eyes of 40 patients with retinal detachments related to coloboma of the choroid without any peripheral breaks were analyzed. All eyes underwent pars plana vitrectomy with internal tamponade using silicone oil. Endolaser was performed along the coloboma border. Silicone oil was removed in 50% of patients. The main outcome measures were retinal reattachment and visual recovery. SPSS (Statistical Package for the Social Science), version 10.0 was used for analysis. RESULTS: The retina in all cases (100%) undergoing vitrectomy were completely reattached intra-operatively. After a mean follow-up of 14 months, 37 (88.1%) eyes had attached retina. The best corrected visual acuity was 10/200 or better in 33 (78.4%) eyes. The best corrected visual acuity improved from a preoperative median of counting fingers (range 20/40 to perception of light) to median best corrected visual acuity of 20/200 (range 20/40 to perception of light) at the end of 6 months. Of the 50% (21) cases that underwent silicone oil removal, two eyes had re-detachment of retina. CONCLUSION: Pars plana vitrectomy along with silicone oil tamponade for retinal detachment related to choroidal coloboma improves the long-term anatomical and visual outcome.

Vitrectomy combined with silicone oil tamponade in the treatment of severely traumatized eyes with the visual acuity of no light perception

AIM: To evaluate the efficacy of surgical treatment of vitrectomy combined with silicone oil tamponade in the treatment of severely traumatized eyes with the visual acuity of no light perception (NLP).METHODS: This was a retrospective uncontrolled interventional case-series of 19 patients of severely traumatized eyes with NLP who underwent vitrectomy surgery at the Affiliated Hospital of Medical College, Qingdao University (Qingdao, China) during a 3-year period. We recorded perioperative factors with the potential to influence functional outcome including duration from the injury to intervention; causes for ocular trauma; open globe or closed globe injury; grade of vitreous hemorrhage; grade of endophthalmitis; grade of retinal detachment; size and location of intraocular foreign body (IOFB); extent and position of retinal defect; grade of proliferative vitreoretinopathy (PVR); type of surgery; perioperative complications and tamponade agent. The follow-up time was from 3 to 18 months, and the mean time was 12 months.RESULTS: After a mean follow-up period of 12 months (3-18 months) 10.53% (2/19) of eyes had visual acuity of between 20/60 and 20/400, 52.63% (10/19) had visual acuity less than 20/400 but more than NLP, and 36.84% (7/19) remained NLP. Visual acuity was improved from NLP to light perception (LP) or better in 63.16% (12/19) of eyes and the rate of complete retinal reattachment was 73.68% (14/19). Good visual acuity all resulted from those patients of blunt trauma with intact eyewall (closed globe injury). The perioperative factors of poor visual acuity prognosis included delayed intervention; open globe injury; endophthalmitis; severe retinal detachment; large IOFB; macular defect; a wide range of retinal defects and severe PVR.CONCLUSION:The main reasons of NLP after ocular trauma are severe vitreous hemorrhage opacity; refractive media opacity; retinal detachment; retinal and uveal damages and defects, especially defects of the macula; PVR and endophthalmitis. NLP after ocular trauma in some cases does not mean permanent vision loss. Early intervention of vitrectomy combined with silicone oil tamponade and achieving retinal reattachment of the remaining retina, may make the severely traumatized eyes regain the VA of LP or better.

Abstract：

Objective To observe the clinical efficacy of vitrectomy on the serious complications of Eales disease. Methods The clinical data of 30 eyes of 27 patients (20 males and 7 females) with Eales disease who underwent vitrectomy were retrospectively analyzed. The age was ranged from 15 to 54 years old, with a mean of 30.7 years. The best corrected visual acuity (BCVA) was ranged from hand movement to 0.5. The patients were divided into the vitreous hemorrhage group (3 eyes ), proliferative vitreoretinopathy group (14 eyes), local retinal detachment group (7 eyes), and wide retinal detachment group (6 eyes) according to the results of examinations. The standard pars plana vitrectomy (PPV) were performed and scleral buckling, lensectomy, endolaser, transscleral cryotherapy/cautery, membrane removal, retinotomy, fluid-air exchange, intravitreal injection of triamcinolone, gas/oil tamponade can be combined if necessary. Those eyes underwent 1 to 8 times (with a mean of 2.4 times) of surgery. The follow-up was ranged from 6 months to 10 years. The BCVA, retinal reattachment, complications before and after surgery was comparatively analyzed. Results At the end of the follow-up, the BCVA was ranged from light perception to 1.5. The BCVA was ＞0.1 in 24 eyes (80.0%) ,0.03 in 1 eye (3.3%), counting finger in 1 eye (3.3%), hand moving in 3 eyes (10.0%) and light perception in 1 eye (3.3%). The BCVA improved in 22 eyes (73.3%), stable in 2 eyes (6.7%) and decreased in 6 eyes (20.0%). The differences are statistically significant between pre- and postoperative BCVA (t=5.132, P＜0.01). The BCVA of wide retinal detachment group was less than other 3 groups (F=4.570, P＜0.05); while the BCVA of vitreous hemorrhage group, proliferative vitreoretinopathy group and local retinal detachment group was the same (P＞0.05). Complete retinal reattachment was achieved in all eyes at the next day after PPV. At the end of the follow-up, retina reattached in 24 eyes without silicone oil tamponade, local retinal detachment occurred in 1 eye (the patient refused further surgery) and silicone oil tamponade-dependant retinal reattachment 5eyes. During the follow-up, 16 eyes (53.3 %) had developed some complications. Conclusions Vitrectomy is an effective way to cure serious complications of Eales disease. The BACV prognosis of patients with wide retinal detachment is poor.
