超声在硅油眼检查中的误诊率

目的 探讨眼科超声在硅油眼检查中诊断视网膜脱离的误诊率.方法 对208例215只眼玻璃体视网膜疾病患者行玻璃体切割及硅油填充术,在硅油填充术前、硅油填充期、硅油取出术后分别进行B超检查.结果 术前超声诊断符合率为100%,硅油填充期超声诊断的准确率为98.60%.误诊率为1.40%.取油后超声诊断的准确率为96.28%,误诊率为3.72%.结论 超声诊断对视网膜疾病的准确率较高,但是也无法完全避免误诊、漏诊情况,尤其是硅油填充时,为避免误诊和漏诊,超声检查时,不但要注意按操作时反复多轴向多切面扫描,仔细观察强回声带运动情况,判断光带与球壁、晶状体、玻璃体的关系,还要密切结合临床其他有关资料,进行综合分析.     

硅油填充眼的B超图像分析

目的：探讨硅油填充眼的B超声像特征和方式。方法：复杂视网膜脱离术中或术后注入硅油37眼,记录其在A．仰位、B．坐位、C．俯位和D．侧位四种不同头位时的超声声像图,按A＋B,A＋B＋C,A＋B＋C＋D分三组分析,号临床检查结果比较。结果：硅油在声像图上表现为均匀的无回声暗区,或内部散在点状、团状回声。乳化时硅油内出现多量高强回声光团。B或D位下可见上方硅油后球壁明显“后移”,并可估计硅油在眼内的容积。C位下可见较清晰的视网膜脱离回声光带。A＋B、A＋B＋C和A＋B＋C＋D三组的敏感度分别为54．5％、81．8％和81．8％,特异度分别为100％、94．4％和100％。结论：硅油内超声波衰减多,A、B、和D位下球壁回声明显减弱,难以辨清。而C位在有硅油眼超声诊断中优势明显,联合多种头位仔细检查可以大大提高诊断准确率。硅油乳化在超声下有特殊的声像图表现,可资鉴别。     

彩色多普勒超声与二维超声诊断外伤性视网膜脱离50例分析

目的：评价彩色多普勒超声在诊断外伤性视网膜脱离中的应用价值。

方法：对2013-01/06于我院就诊的眼外伤可疑视网膜脱离的患者50例56眼先行二维超声检查,再行彩色多普勒超声检查,并与手术结果对照。

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.

Abstract：

Objective To investigate the feasibility of using magnetic resonance imaging (MRI) to measure the visual axis length in silicone oil filled eyeballs. Methods Thirty-two silicone oil-filled eyes of 32 patients were studied. The ante-silicone oil spaces (ASS) and retro-silicone oil spaces (RSS) on the visual axis was measured on the cross-sectional T1 weighted images (T1 WI) and T2WI, the length of the visual axis was measured on the fat-suppressed T2WI. The length of the visual axis was the distance from the corneal vertex to the macular foves, and it was also measured by A-mode ultrasound in sitting position with different ultrasonic velocity. The post-oil gap was also measured by A-mode ultrasound in supine position.Results Compared with the signal of the contralateral vitreous body, the silicone oil signal was higher on T1WI images, lower on T2WI images. After fat suppression, the silicone oil signal and chemical shift artifact were reduced. There were different levels of ASS and RSS in the vitreous cavity of all 32 cases, the RSS depth was (2. 47 ± 1.31) mm on average by MRI. However, RSS was detected in only 56.25%(18 cases) eyeballs by A-mode ultrasound. The visual axis length of silicone oil-filled eyes was (23.52 ±4.67) mm by MRI, and (20. 57±5.32) mm by A-mode ultrasound in sitting position. The differences between two measurements was statistically significant (t= 30. 17, P＜0. 05). Conclusions In addition to A-mode ultrasound, MRI might be another effective method to detect RSS and ASS, and to measure the axial length of silicone oil-filled eyes.     

两种手术方法治疗非后极部多发裂孔性视网膜脱离的比较

目的：观察非后极部多发裂孔性视网膜脱离的临床特征,探讨玻璃体切割术和巩膜扣带术的疗效。

方法：回顾性分析2017-06/2018-08在我院眼科住院行手术治疗的非后极部多发裂孔性视网膜脱离患者40例40眼,按手术方式不同分为玻璃体切割术(PPV)组(18眼)和巩膜扣带术(SB)组(22眼)。术后随访3～6mo,观察两组患者的手术疗效。

结果：至末次随访,PPV组患者视网膜复位率为100%(18/18),去除硅油填充眼后视网膜复位率为56%(10/18)。SB组患者视网膜复位率为86%(19/22),无硅油填充眼。两组患者视网膜复位率比较(包括硅油填充眼),差异无统计学意义(P>0.05),去除硅油填充眼后视网膜复位率比较有差异(P<0.05)。

结论：非后极部多发裂孔性视网膜脱离多为视网膜广泛变性或合并玻璃体牵拉引起。复杂病例宜选择玻璃体切割术,但需多次手术,而巩膜扣带术远期效果稳定。两种手术方法各有利弊,应综合考虑,不应盲目扩大玻璃体切割术适应证。对于年轻或独眼等特殊群体,如有可能应尽可能优先选择巩膜扣带术。     

The results of B-scan ultrasonography in different positions after vitrectomy and gas tamponade

PURPOSE: To determine the proper time frame in which to assess retinal attachment status and to evaluate the superior retinal attachment status by performing B-scan ultrasonography in different positions on patients who have undergone pars plana vitrectomy and gas tamoponade. METHODS: In this prospective study, 23 patients (23 eyes) who had undergone pars plana vitrectomy and gas tamponade were investigated between June 2005 and February 2006. SF(6) (18%) was injected into the vitreous cavity of 15 eyes, and C(3)F(8) (14%) was injected into the vitreous cavity of 8 eyes. At postoperative day 1, day 3, week 1, week 2, and week 4, B-scan ultrasonography was performed in the supine, sitting, prone, right decubitus, and left decubitus positions. RESULTS: The proper time to evaluate the retinal attachment status was three days post-operatively in 10 eyes (66.7%) with SF(6) (18%) injections and two weeks post-operatively in six eyes (75%) that had C(3)F(8) (14%) injections. The superior retinal attachment status can be evaluated from the summation of B-scan ultrasonography results performed in the right decubitus and left ducubitus positions. CONCLUSIONS: The proper time to evaluate the retinal attachment status was related to the degree of the gas absorption when performing B-scan ultrasonography after pars plana vitrectomy and gas tamponade. To evaluate the entire retina, it is useful to perform B-scan ultrasonograhy in the prone, right decubitus and left decubitus positions.

Biometry and refractive outcome of eyes filled with silicone oil by standardized echography and partial coherence interferometry

Background We evaluated the validity of calculations for refractive outcome in cataract surgery in silicone oil-filled eyes. The retrosilicone space (RSS) was included in these calculations. Methods In a prospective study the axial length (AL) of silicone oil-filled eyes was measured. with standardized A-scan echography (SAE) and partial coherence interferometry (PCI). Meldrum’s formula was used to transform the velocity of ultrasound within the vitreous cavity. To investigate whether refractive outcome can be calculated accurately, we assessed the difference between precalculated and final refractive outcome. Furthermore, we determined the advantages and disadvantages of SAE and PCI. A minor aim was to assess whether theAL of the two eyes differed significantly. Results In 85% of 117 eyes the difference between precalculated and postsurgical refraction was smaller than 1 diopter spherical and statistically not significant (p>0.2). The mean AL was 24.1 mm (range 20.0–31.4 mm). The difference in outcome between the two methods was without statistical significance: the AL difference was 0.4 (±2.6) mm on measurement with SAE and 0.04 (±0.46) mm with PCI. PCI has the advantage that it can be performed more easily, without contact, while echography is advantageous in the presence of advanced cataracts. In supine position an oil-free fluid space behind the silicone oil was detected with echography. The mean dimension of this space was 1.9 (±0.67) mm and it was taken into consideration for IOL calculation. The mean AL difference between the two eyes was 0.4 mm, but the difference was greater than 1 mm in 26% of the patients. Conclusion The AL of eyes filled with silicone oil can be measured reliably with SAE and PCI. In supine position the RSS has to be considered to obtain more accurate IOL calculations.
