黄斑裂孔视网膜脱离的手术治疗

目的分析黄斑裂孔视网膜脱离的手术方法及效果。方法黄斑裂孔视网膜脱离26例（26只眼）,术前常规检查视力、眼压、屈光情况,眼底检查采用三面镜和间接眼底镜,查明玻璃体液化情况以及有无后脱离,黄斑孔有无牵引,膜增生情况,周边视网膜是否伴有裂孔,脱离范围、程度,并以此为依据来决定手术方式。选择脱离范围局限于后极部、伴有玻璃体后脱离、无明显膜形成以及无黄斑孔牵引者,行单纯的玻璃体腔内注入惰性气体C3F8者0.5～0.8ml,4只眼行此手术;选择黄斑裂孔伴有周边裂孔,视网膜脱离范围较广泛者16只眼行巩膜外垫压必要时环扎加玻璃体腔注气术,注入C3F8者0.5～1.0ml;选择膜增生明显、脱离范围广泛、有明显黄斑裂孔牵引者8只眼（其中2只眼为二次手术）行玻璃体切割加注气术或硅油注入术。结果手术后视网膜最终复位24只眼,复位率92.3%（24/26）。单纯注气的4只眼,有1只眼气体吸收后再次脱离,脱离范围仍然比较局限,无明显增殖,经再次气体注入后复位;巩膜外垫压加必要时环扎加玻璃体腔注气术16只眼,其中3只眼再次脱离,2只眼查明有新裂孔的形成,1只眼黄斑裂孔封闭不良再次脱离,1只眼放弃治疗,2只眼进行玻璃体切割手术最终复位。玻璃体切割加注气术或硅油注入术8只眼,2只眼复发,其中1只眼为白孔,经注气失败后改为注入硅油后成功,1只眼玻璃体增生明显,造成继发裂孔,放弃治疗。手术前后视力比较,均有不同程度的提高。结论对于黄斑裂孔视网膜脱离的患者术前都要进行仔细认真地检查,依据裂孔的性质、部位、大小、脱离的范围、增生膜的情况来决定手术方式,可以减少不必要的手术损伤和并发症的发生,来获得最大的视功能的康复和视网膜的解剖复位。

Clinical observations of vitreoretinal surgery for four different phenotypes of X-linked congenital retinoschisis

AIM: To evaluate the outcomes of vitreoretinal surgery for four different phenotypes of X-linked retinoschisis (XLRS). METHODS: This study included thirty-one eyes of 25 patients who developed XLRS with severe complications. Among the 31 eyes, there were 7 eyes with vitreous hemorrhage, 8 eyes with retinal detachment and vitreous hemorrhage, and 16 eyes with rhegmatogenous retinal detachment. All of the patients underwent standard three-port pars plana vitrectomy. All of the eyes were divided into 4 groups before surgery according to a modified classification scheme, with the first three groups as follows: group A, with foveal cystic schisis; group B with macular lamellar schisis; and group C with foveolamellar changes. Peripheral schisis was not present in these 3 groups; however, group D was a complex group with both macular and peripheral changes. One year after surgery, we analyzed the best corrected visual acuity and postoperative anatomical and functional outcomes of these 4 groups. RESULTS: There were 7 eyes in group A (22.6%), 1 eye in group B (3.2%), 15 eyes in group C (48.4%) and 8 eyes in group D (25.8%). Postoperative anatomical and functional outcomes were satisfactory at the last visit, while the mean visual acuity was increased to 0.27±0.11, with a significant difference (t=-1.049, P=0.000) compared with the results before surgery (0.1±0.08). Visual acuity was improved in 23 eyes (74.2%). Complications were found in three eyes: two eyes with proliferative vitreoretinopathy and traction retinal detachment 10 and 12mo after surgery, respectively; and one eye with vitreous hemorrhage 15mo after surgery. These eyes were in groups C and D. The retinas remained attached in these 3 eyes after reoperation. CONCLUSION: We should pay greater attention to XLRS with foveolamellar changes because it is the most changeable phenotype. Once complications occur, vitreoretinal surgery can significantly improve visual acuity and restore the anatomic structure of the retina.     

Plasmin enzyme-assisted vitreoretinal surgery in congenital X-linked retinoschisis: surgical techniques based on a new classification system

PURPOSE: To review the surgical outcome of autologous plasmin enzyme-assisted vitreoretinal surgery in managing complications associated with congenital X-linked retinoschisis (CXLRS). METHODS: Medical records of 20 patients (22 eyes) with CXLRS complications, treated with autologous plasmin enzyme-assisted vitreoretinal surgery, were reviewed. Surgical techniques were adapted according to a new CXLRS classification. RESULTS: Median age of the cohort was 3.5 years. Indications for surgical intervention included 8 eyes with schisis involving or threatening the macula, 7 eyes with rhegmatogenous retinal detachment, 4 eyes with tractional retinal detachment, 1 eye with vitreous and intraschisis hemorrhage, 1 eye with obstruction of the macula by an overhanging bullous schisis cavity, and 1 eye with macular pucker. Ninety-one percent (20/22) of eyes had retinal attachment postoperatively after an average of 1.3 procedures per eye. Of the eyes in which visual acuity was measured, 53% (8/15) improved, 33% (5/15) had no change, and 13% (2/15) lost vision. CONCLUSION: Plasmin enzyme-assisted vitreoretinal surgery is a safe and effective method for managing the complications associated with CXLRS. Most patients had improved or stable postoperative visions.

Clinicopathologic findings in anterior hyaloidal fibrovascular proliferation after diabetic vitrectomy

Two young patients (27 and 30 years old, respectively) with long-standing diabetes mellitus underwent vitreoretinal surgery for traction retinal detachment and vitreous hemorrhage. The postoperative course in each was characterized by early recurrence of the hemorrhage into the vitreous cavity, hypotony, and severe visual loss. Histopathologic examination of both operated on eyes showed anterior extraretinal fibrovascular proliferation extending along the anterior hyaloid to the posterior lens surface, causing traction detachments of the peripheral retina and ciliary body. The vessels originated from the anterior retina. There was no evidence of excess fibrous tissue at the well-healed sclerotomy wounds.     

Combined surgery, phacoemulsification, implantation of intraocular lens and pars plana vitrectomy

PURPOSE: To evaluate the effectiveness, technical feasibility and incidence of complications after combining pars plana vitrectomy, phacoemulsification and intraocular lens implantation. MATERIAL AND METHODS: The results of combined vitreoretinal and cataract surgery in 100 eyes of 96 patients were retrospectively and prospectively analyzed. The mean follow-up period was 8.4 months. All patients had clinically significant lens opacities and vitreoretinal pathology requiring pars plana vitrectomy. Indications for vitreoretinal surgery included: persistent vitreous haemorrhage (28 eyes), vitreous hemorrhage combined with tractional retinal detachment (50 eyes), tractional retinal detachment without vitreous haemorrhage caused by proliferative diabetic retinopathy (7 eyes), rheumatogenous retinal detachment with proliferative vitreoretinopathy (10 eyes) and dislocated crystalline lens in the vitreous (5 eyes). RESULTS: Postoperatively, best corrected visual acuity improved in 81 eyes (81%)- by two lines or more in 31 eyes (31%) - by less than two lines in 50 eyes (50%). In 14 eyes (14%) visual acuity was unchanged and was worse in 5 cases (5%). Postoperative complications included fibrin reaction, posterior synechias of the iris, vitreous hemorrhage, neovascular glaucoma, posterior capsule opacification, redetachment of retina. CONCLUSIONS: Our cases confirm previous study, that performing phacoemulsification, IOL implantation and vitrectomy in one operation is safe and allows visual recovery with good technical results.     

Surgical management of retinoschisis

Most cases of X-linked juvenile retinoschisis and degenerative retinoschisis never require any type of surgical intervention. However, on rare occasions, associated problems such as retinal detachment come about and threaten the visual prognosis. Both conditions have in common the adherence of cortical vitreous to the inner layer of peripheral schisis cavities, which can make the secondary complications technically difficult to manage. Although good surgical results can often be obtained, it is not unusual to require relatively advanced vitreoretinal techniques to achieve long-term surgical success.
