  macular
OCT showed that the macular edema disappeared or was alleviated.
      
This paper reports a case study of a distinctive variant of adenoma of the NPCE, which clinically appears as epiretinal membrane in the macular region.
      
Carotenoids lutein and zeaxanthin are proposed to protect ocular tissues from free-radical damage that can cause cataract and age-related macular degeneration (AMD).
      
They accumulate selectively in the lens and macular region of the retina.
      
Increasing zeaxanthin in common foods such as potatoes by traditional plant breeding or by genetic engineering could contribute to an increased intake of this carotenoid and, consequently, to a decreased risk of age-related macular degeneration.

Nous avons déerit une méthode du triage des enfants amblyopiques qui sont ensuite traités selon différents modes de correction. Une analyse a été faite sur l'effet des durées des cours de traitement sur l'acuité visuelle des 116 yeux amblyopiques traités.Le groupe traité pendant 3 à 6 mois comprenait 34 yeux, contenant seulement 1 oeil avec une acuité visuelle plus que 0, 6 avant traitement, ce chiffre monta à 22 après traitement.

Nous avons déerit une méthode du triage des enfants amblyopiques qui sont ensuite traités selon différents modes de correction. Une analyse a été faite sur l'effet des durées des cours de traitement sur l'acuité visuelle des 116 yeux amblyopiques traités.Le groupe traité pendant 3 à 6 mois comprenait 34 yeux, contenant seulement 1 oeil avec une acuité visuelle plus que 0, 6 avant traitement, ce chiffre monta à 22 après traitement. Dans le groupe traité pendant 7 à 10 mois, le nombre d'yeux possédant une acuité visuelle plus que 0,6 changea de 3 (avant traitement) à 70 (après traitement). Ceci démontre que, les résultats étaient beaucoup meilleurs quand les cours de traitement duraient plus de 7 mois. Parmi les 116 yeux traités, une fixation maculaire centrale a été notée ehez 45 yeux avant traitement, elle a été observée chez 92 yeux après traitement.

本文介绍了弱视儿童的筛选和矫治方法,对116只弱视眼作了不同疗程的视力分析,3~6个月治疗组为34眼,视力0.6以上者治疗前1眼治疗后增至22眼。7~10个月治疗组为82眼,视力0.6以上者由3眼增到70眼。说明疗程超过7个月者效果更显著。在116眼治疗中黄斑中心凹注视者治疗前仅45眼而治疗后育92眼。

There are 174 cases of primary retinal detachment reported in our ar ticle. 128 eyes were treated with surgical method. In all these cases myopes accounted for 82.2%, high degree of myopia 45%. Round holes were mostly seen; horse-shoe hole and other types of holes occurred less. Holes on the quadrant of retina occurred in the following order: upper temporal, lower temporal, lower nasal and upper nasal. The number of holes on the temporal half retina was more than three times as high as that on the nasal half....

There are 174 cases of primary retinal detachment reported in our ar ticle. 128 eyes were treated with surgical method. In all these cases myopes accounted for 82.2%, high degree of myopia 45%. Round holes were mostly seen; horse-shoe hole and other types of holes occurred less. Holes on the quadrant of retina occurred in the following order: upper temporal, lower temporal, lower nasal and upper nasal. The number of holes on the temporal half retina was more than three times as high as that on the nasal half. The site of holes was largely located in between the equator and the ora serrata (77%). The surgical methods we adopted were simple electro-coagulation, scleral shortening and silicone strap. We insist that the retinal break should be on the summit of the indentation andon the anterior slope of silicone strap which is parallel with the equator. Macula holes should be treated with ruby laser. The result was not affected by the surgical method or the pcesence of a hole, but the area of retinal detachment had some influence on the result. The relations between retinal detachment and myopia, the condition of retinal detachment and the site of the hole as well as the method of surgery used, the problem of drainage of subretinal fluid and the causes of the surgical failure were discussed.We believe that drainage of subretinal fluid is very important.

本文报告174例原发性视网膜脱离的病例,128只眼施行了手术。近视眼占82.2%,高度近视占45%。裂孔以园形最多,马蹄形及其他形态的裂孔次之。发生裂孔的象限依次为颞上、颞下、鼻下、鼻上;颞半侧裂孔数约为鼻半侧的三倍强。裂孔的位置在赤道部与锯齿缘之间者最多,占77%。手术方式采用单纯电凝、巩膜层间缩短和硅胶填压。我们主张填压必须针对裂孔,位于裂孔后缘并与赤道平行。黄斑部裂孔应用红宝石激光治疗。术式与裂孔的有无和疗效无明显关系,脱离的范围与疗效有关。本文对近视与网膜脱离的关系,网膜的情况与裂孔位置的关系、手术方式问题、放水问题与手术失败的原因进行了讨论,认为放水是很重要的。

Many diseases may cause cystoid ma- cular edema(CME),which suggests that CME is not an independent disease,but a clinical sign and result caused by many diseases.We present 52 cases with cystoid macular edema and study the fluorecein angiograms,clinical observation and visual prognosis. These diseases were central retinal vein occlusion (50 cases),retinal angiomatosis(1 case),chorioretinitis (1 case),Fluorecein angiography showed abnormal perifoveal retinal capillary permeability,which formed a flower-petal...

Many diseases may cause cystoid ma- cular edema(CME),which suggests that CME is not an independent disease,but a clinical sign and result caused by many diseases.We present 52 cases with cystoid macular edema and study the fluorecein angiograms,clinical observation and visual prognosis. These diseases were central retinal vein occlusion (50 cases),retinal angiomatosis(1 case),chorioretinitis (1 case),Fluorecein angiography showed abnormal perifoveal retinal capillary permeability,which formed a flower-petal pattern.There were 128 angiograms(97 cases)with central retinal vein occlu- sion.The incidence of CME was 51.55%(50 cases). The average follow-up period was 12 months.The visual acuity in 22% eyes with CME recovered to 0.6 or better,while 78.72% eyes with no CME recovered to 0.6 or better.Comparison between the two groups showed P<0.005.The results suggest that CME affects the visual prognosis apparently. 5 cases with histopathologic features of CME were examined.The cystoid spaces were seen in the outer plexiform layer,inner nuclear layer,inner plexiform layer,ganglion cell and nerve fibre layers. In severe cases,cystoid spaces were seen in every layer of the retina and extended from the optic disc to the equator.Simultaneously vessel occlusion,retinal pigment epithelial atrophy and retinal degeneration were seen,which suggest that CME not only affects visual acuity but also is the reason of poor visual acuity in some cases.

许多眼病可产生黄斑囊样水肿,它不是一个独立的疾病,而是各种眼病所产生的临床症状和后果。本文报告52例黄斑囊样水肿荧光造影,临床观察和视力预后。产生黄斑囊样水肿的眼病是视网膜中央静脉阻塞50例,视网膜血管瘤一例,脉络膜视网膜炎一例。荧光造影显示黄斑毛细血管拱环有程度不同的渗漏,并形成花瓣状图形。视网膜静脉阻塞共作荧光造影97例128人次,黄斑囊样水肿的发病率为51.55%(50例)。平均追踪观察时间为12个月。视力恢复在0.6以上者,有黄斑囊样水肿组为22%,无黄斑囊样水肿组为78.72%,两组比较,P<0.005。说明黄斑囊样水肿明显影响视力预后。观察了5例黄斑囊样水肿组织病理学切片。囊样空间位于外丛状层、内核层、内丛状层、神经节细胞层、神经纤维层。严重者可位于视网膜各层,并从视乳头伸向赤道部。同时可看到血管阻塞和视网膜退行性变,色素上皮萎缩等,提示黄斑囊样水肿不但影响视力,并且是视力严重减退的原因。
