Optical coherence tomography of the neurosensory retina in rhegmatogenous retinal detachment

PURPOSE: To clarify the pathologic changes of the detached neurosensory retina in rhegmatogenous retinal detachment. METHODS: Retinal images were prospectively examined by optical coherence tomography in 25 eyes of 25 consecutive patients with rhegmatogenous retinal detachment. We excluded the patients whose retinal detachment did not involve the central fovea or patients with poor fixation during optical coherence tomography (OCT) examination. Optical coherence tomography was scanned through the center of the fovea. The patients ranged in age from 15 to 77 years (mean, 45 years; SD, 20 years). The period from onset of subjective symptoms of retinal detachment to OCT ranged from 2 to 60 days (mean, 16 days; SD, 18 days). Optical coherence tomography findings, best-corrected visual acuity, and the height of the retinal detachment at the central fovea were statistically analyzed using ANCOVA (analysis of covariance) and the Mann-Whitney U test. RESULTS: In 25 eyes of 25 patients, OCT of the detached neurosensory retina at and adjacent to the center of the fovea demonstrated normal retinal structure (10 eyes, 40%), intraretinal separation (7 eyes, 28%), and an undulated separated outer retina (8 eyes, 32%). Three statistically significant factors affected best-corrected visual acuity: intraretinal separation (P = .001), intraretinal separation with undulated outer retina (P = .001), and height of retinal detachment at the central fovea (P<.001). Best-corrected visual acuity was significantly worse in the 15 eyes with intraretinal separation with or without an undulated outer retina than in the 10 eyes with retinal thickening but no intraretinal separation (P = .036). The eight eyes with undulated separated outer retina showed significantly higher retinal detachment at the central fovea than the seven eyes with intraretinal separation but no undulated outer retina (P = .009) and the 10 eyes without intraretinal separation (P = .016). The duration from onset of subjective symptoms to OCT was not related to the occurrence of intraretinal separation of the detached retina. CONCLUSIONS: Intraretinal separation of the detached retina occurred frequently and shortly after retinal detachment in rhegmatogenous retinal detachment and was one of the factors associated with poor vision in rhegmatogenous retinal detachment. Best-corrected visual acuity significantly decreased in the highly detached retina.

Long-term results of vitreous surgery for proliferative diabetic retinopathy

In order to study long-term anatomical and functional results the authors evaluated the data from 260 patients who underwent pars plana vitrectomy for proliferative diabetic retinopathy. Indications for surgery were: vitreous hemorrhage, 68 eyes (26.2%); vitreous hemorrhage & tractional retinal detachment, 84 eyes (32.3%); tractional retinal detachment, 82 eyes (31.5%); and combined tractional-rhegmatogenous retinal detachment, 26 eyes (10%). In 118 eyes vitreoretinal surgery was combined with silicone-oil tamponade.The retina was completely attached posterior to a scleral buckle in 251 eyes (96%) at the time of the last examination. After a follow-up period of at least 12 months in a group of patients with vitreous hemorrhage, visual acuity improved in 88% of the eyes. Visual acuity was better than 0.5 in 31% of eyes. In group of eyes with nonresorbing vitreous hemorrhage & tractional retinal detachment visual acuity improved in 52% of eyes. Visual acuity improved in 76% of eyes with tractional retinal detachment and in 81% of eyes with combined tractional & rhegmatogenous retinal detachment. When comparing the latest postoperative visual acuity to visual acuity after three months postoperatively, visual acuity was unchanged in 88%, in 10% it became worse and in 3 cases (1%) became better. In the postoperative period, recurrent vitreous hemorrhage occurred in 33 (13%) eyes, reproliferation in 12 eyes.Cataract developed in 45 of 168 phakic eyes. If postoperative visual acuity before cataract formation was good, extracapsular cataract extraction with posterior chamber intraocular lens implantation was performed. Otherwise simple intra or extracapsular cataract extraction was performed. In 19 cases cataract operation was performed together with silicone oil extraction. Neovascular glaucoma developed postoperatively in 15 eyes (6%). Retinal detachment occurred postoperatively in 21 eyes (8%). In 15 eyes the retina was successfully reattached after additional operations.

Signs, complications, and platelet aggregation in familial exudative vitreoretinopathy

Between 1979 and 1989, I examined 106 patients (16 pedigrees) with signs of familial exudative vitreoretinopathy. Of these patients, 101 had familial exudative vitreoretinopathy, and five had a sporadic manifestation. The complications of familial exudative vitreoretinopathy, deformation of the posterior retina, vitreous hemorrhage, amblyopia, and retinal detachment, caused diminished visual acuity. Of 170 eyes, retinal neovascularization was observed in 18 eyes (11%), and retinal exudates were observed in 16 eyes (9%). Several forms of retinal detachment occurred in 37 of 180 eyes (21%), which often took an unfavorable course. A falciform retinal fold was observed in 14 eyes (8%). Retinal surgery was performed in 14 eyes; reattachment of the retina was successful in only seven eyes. Platelet aggregation studies disclosed no significant differences between seven patients with familial exudative vitreoretinopathy and ten control subjects. The pathogenesis of the disease is based on a premature arrest of the vascular development of the retina.

目的 观察永存原始玻璃体增生症(PHPV)的手术治疗效果。 方法 回顾性分析接受玻璃体视网膜手术治疗的16例PHPV患者16只眼的临床资料。患者中男性9例，女性7例，年龄3个月~25岁，平均年龄51.9个月。14例为单眼发病，2 例为双眼发病，均未合并全身异常。其中，前部型3只眼，混合型13只眼；10只眼合并白内 障，7只眼合并虹膜后粘连，5只眼合并浅前房，3只眼合并角膜带状变性，1只眼角膜混浊， 2只眼合并牵引性视网膜脱离，1只眼合并牵引性孔源性视网膜脱离。手术前视力1只眼为光感，1只眼为眼前手动，1只眼为数指/10 cm，1只眼为0.02，12只眼不能配合视力检查，对强光刺激反应不明显。13只眼行晶状体切除和前段玻璃体切割，1只眼1期植入人工晶状体， 3只合并视网膜脱离眼行晶状体切除、玻璃体切割、眼内激光光凝、注气、巩膜环扎手术 。 手术后随访时间6个月至4年，平均随访时间为15.3个月。 结果 所有接受手术治疗眼手术后眼压均正常，前房形成，视网膜复位。混合型者残留视盘前纤维血管膜及视网膜皱襞。2例患者经弱视训练后最佳矫正视力达02和01，8例不配合视力检查者有遮盖厌恶反应，均对强光刺激有反应，6例患者视力低于数指。 结论 对于前部型和混合型PHPV患者，早期晶状体切除及玻璃体手术可以重建视觉通道并解除牵引 ，保存视力，减少继发性青光眼等并发症的发生，结合手术后弱视训练可获得有用视力。 （中华眼底病杂志，2008，24：210-212）     

Anatomic and visual results in asymptomatic clinical rhegmatogenous retinal detachment repaired by scleral buckling

PURPOSE: To report presenting characteristics as well as anatomic and visual results in asymptomatic clinical rhegmatogenous retinal detachment repaired by scleral buckling. METHODS: Review of 28 eyes of 27 patients with an asymptomatic clinical retinal detachment-defined as a rhegmatogenous retinal detachment with subretinal fluid extending more than 2 disk diameters posterior to the equator-which were repaired by scleral buckling from January 1989 through December 1996 with follow-up of 6 months or longer. RESULTS: With a single scleral buckling procedure, anatomic reattachment of the retina occurred in all eyes; one eye redetached 14 months after the initial surgery secondary to a new retinal break and was successfully reattached. All eyes had best-corrected presenting and final visual acuity of 20/50 or better. Final best-corrected Snellen visual acuity was within 1 line of best-corrected presenting visual acuity in 82% of eyes; three eyes improved more than 1 line of Snellen visual acuity and two eyes lost more than 1 line. CONCLUSION: Anatomic and visual results in asymptomatic clinical rhegmatogenous retinal detachment after scleral buckling surgery are excellent. Strong consideration should be given to repair of these detachments.
