目的 探讨经瞳孔温热疗法(traspupillary thermotherapy, TTT)治疗中心性渗出性脉络膜视网膜炎(central exudative chorioretinopathy,CEC)的临床效果。 方法 对荧光素眼底血管造影(fundus fluorescein angiography,FFA)和吲哚青绿血管造影(indocyanine green angiography,ICGA)检查确诊的CEC患者的12只患眼进行TTT治疗。采用810 nm半导体激光,光斑0.5~2.0 mm,照射时间55~60 s,能量200~350 mW,对 FFA和ICGA图像所显示的脉络膜新生血管(choroidal neovascularization,CNV)进行照射,照射区未出现颜色变化或呈淡灰色。对比分析患者治疗前后的视力、眼底、FFA和ICGA检查结果。 结果 TTT治疗后0.5~3个月后所有患眼视力都有不同程度提高,视力提高5行以上者4只眼,占33.3%;3~5行者 5只眼,占41.7%;1~2行者 3只眼,占25.0%。治疗后10只眼行FFA和ICGA复查,其中FFA复查荧光素渗漏消失7只眼,减轻3只眼;ICGA复查CNV消失或明显缩小8只眼,CNV无变化2只眼。 结论 TTT治疗CEC效果良好,值得临床推广应用。 (中华眼底病杂志, 2002, 18: 187-189)  相似文献

目的
观察中心性渗出性脉络膜视网膜病变(central exudative chorioretinopathy,CEC)脉络膜新生血管(choroidal neovascularization,CNV)的光学相干断层扫描(optical coherence tomography,OCT)图像特征。
方法
对41例发病时间从1周~10个月的CEC患者的 43只患眼进行荧光素眼底血管造影(fundus fluorescein angiography,FFA)和OCT检查,其中27只患眼在 FFA检查的同时进行了吲哚青绿眼底血管造影(indocyanine green angiography,ICGA)检查。对比分析其CNV的OCT和 FFA及ICGA图像特征。
结果
CEC的OCT图像表现为边界清楚的CNV(41.86%)、边界不清的 CNV(30.23%)、出血性色素上皮脱离(pigment epithelium detachment,PED)(16.28%)、伴有浆液性(6.98%)或出血性神经上皮脱离的CNV(4.65%) 5种形态。其中以边界清楚的CNV和边界不清的CNV为主,共占72.09 %。视网膜血管造影,能清楚确定CNV的边界者,FFA、ICGA检查分别为12、20只眼;OCT从视网膜断层切面上能清楚确定CNV边界者23只眼。FFA检查上典型的CNV,OCT图像通常也表现为边界清楚的CNV;FFA检查上非典型的CNV,OCT图像表现为多种形态。
结论
CEC的OCT图像特征以边界清楚的CNV和边界不清的CNV为主。OCT检查可以从视网膜断面上准确观察CEC病灶视网膜及脉络膜毛细血管层的形态,对FFA、ICGA从视网膜脉络膜平面上对CNV的观察有很好地补充作用。

The author defines motor and sensory alternation: the term alternation should not be used in isolation, it should always be accompanied by the name of the parameter concerned. Sensory alternation is always found together with motor alternation but the reverse is not true.The examining criteria for a diagnosis of sensory alternation are given, sensory alternation must not be confused with alternating inhibition. Working from clinical observations of cases of motor alternating strabismus, the author selects 2 types of binocular sensory relations which allow one to differentiate between:- cases of primary alternating strabismus- cases of secondary alternating strabismusThese forms will develop in different ways; in both cases a cure is possible providing that the right treatment is prescribed and once prescribed carefully followed, etc. It is always a case of serious forms of strabismus whose developmental period is spread over several years.According to the authors, the frequency of cases of true primary strabismus is from 1–3%, the frequency of cases of secondary alternating strabismus varies according to the type of therapy practised on cases of monocular strabismus with amblyopia. These latter will become cases of alternating strabismus under the influence of certain types of therapy carried out over several years (penalization, rocking, alternated occlusion, etc...).Experimental data on kittens confirm clinical data; kittens placed in abnormal environments during the sensitive period will show modification in the distribution of cortical cells and the absence of binocular cells (either because the excitation of the two eyes was not simultaneous, or not identical: artificial strabismus, occlusion, opaque glasses). This disturbances become irreversible after a certain period of exposure (a function of age, length of exposure, etc...).It is thus necessary to bear in mind: 1) the iatrogenic risks of certain orthoptic treatments, 2) the necessity for a binocular form of treatment as soon as possible, as once a certain stage is passed, cortical plasticity diminishes and the elaboration of normal binocular relations becomes impossible.

The effects of single or multiple topical doses of the relatively selective A1adenosine receptor agonists (R)-phenylisopropyladenosine (R-PIA) and N6-cyclohexyladenosine (CHA) on intraocular pressure (IOP), aqueous humor flow (AHF) and outflow facility were investigated in ocular normotensive cynomolgus monkeys. IOP and AHF were determined, under ketamine anesthesia, by Goldmann applanation tonometry and fluorophotometry, respectively. Total outflow facility was determined by anterior chamber perfusion under pentobarbital anesthesia. A single unilateral topical application of R-PIA (20–250 μg) or CHA (20–500 μg) produced ocular hypertension (maximum rise=4.9 or 3.5 mmHg) within 30 min, followed by ocular hypotension (maximum fall=2.1 or 3.6 mmHg) from 2–6 hr. The relatively selective adenosine A2antagonist 3,7-dimethyl-1-propargylxanthine (DMPX, 320 μg) inhibited the early hypertension, without influencing the hypotension. Neither 100 μg R-PIA nor 500 μg CHA clearly altered AHF. Total outflow facility was increased by 71% 3 hr after 100 μg R-PIA. In conclusion, the early ocular hypertension produced by topical adenosine agonists in cynomolgus monkeys is associated with the activation of adenosine A2receptors, while the subsequent hypotension appears to be mediated by adenosine A1receptors and results primarily from increased outflow facility.  相似文献
