  • 国产染料激光机光凝治疗黄斑水肿60例

    用国产眼科染料激光机光凝治疗几种眼底病引起的黄斑水肿60例60只眼。平均追踪观察6个月,39眼(65.00%)视力有提高,其中病程3个月以内的有30只眼(76.92%).眼底荧光血管造影复查60只眼,49只眼(81.67%)的黄斑区荧光素渗漏有不同程度减轻,8只眼(13.33%)的消失。其中以分支静脉阻塞(30只眼)疗效最好,视力提高者27眼(90.00%),复查眼底荧光血管造影好转和正常者29眼(96.66%).黄斑水肿光凝治疗的效果与病程长短有关,与病种有关,与黄斑区出血范围大小有关。并介绍了国产眼科染料激光机的特点。 (中华眼底病杂志,1996,12:46-47)

  • Relationship between retinal extracellular edema and vitreous contraction in rabbits

    Objective To explore the correlation between retinal extracellular edema and vitreous contraction in rabbits. Methods Seventeen pigmented rabbit models with retinal vein occlusion (RVO)was set up by laser photocoagulation. Retinal vascularity area was pathologically examined 1 month later.The vitreous gellength under the gravity condition and the percentage of its weight in the rabbits with extraeellular edema was observed. The mechanisms were investigated by Western immunoblotting of type II collagen.Results Extracellular edema was found in 13 experimental eyes 1 month after the formation of RVO (76.5~) with contracted vitreous gel and released watery liquid, and the a component of type II collagen was cross-linked together to form high-molecular-weight components of 1] and 7, which weakened the stability of collagen net structure.Conclusions Vitreous contraction and retinal extracellular edemawere correlated. The main reason may be the cross-links of vitreous collagen that damages the stability of collagen structure. (Chin J Ocul Fundus Dis,2004,20:2-32)

  • A study on the short-term fluctuation of macular light threshold in suspected early age-related macular dege-neration

    Objective To study the significance of detection the short-term fluctuation (SF) of macular light threshold detected by Octopus-123 automatic perimeter in suspected early age-related macular dege-neration (AMD). Methods SF of macular light sensitivity, Amsler chart and central visual acuity were examined in 51 patients(66 eyes) with suspected early AMD group and in 32 patients (40 eyes) in the control group. Results SF were significantly different in suspected early AMD group and control group. SF was more sensitive than the examination of central visual acuity and Amsler chart. SF was related to the quantity, location and quality of drusen. Conclusion Visual function of some suspected early AMD patients with drusen may be damaged, though the central visual acuity appears normal. (Chin J Ocul Fundus Dis, 2002, 18: 119-120)

  • Characteristics of optical coherence tomography for several common diseases which could lead to submacular choroidal neovascularization

    ObjectiveTo observe and classify the characteristics of optical coherence tomography (OCT) for several common diseases which could lead to submacular choroidal neovascularization (CNV), and to provide the warrant to make the differential diagnosis and treatment of CNV.MethodsThe data of OCT of 165 patients (187 eyes) with CNV due to AMD, CEC, high myopia and ICNV diagnosed by fundus photography and fundus fluorescein angiography (FFA) were retrospectively analyzed, and the images of OCT were classified considering the results of FFA, and the characteristics of different types of the images were sumerized.ResultsWell-defined fusiform thickening of retinal pigment epithelial (RPE) and choriocapillary layer in CNV with well-defined border (60 eyes), dispersed backscattering increase in poorly-defined CNV (101 eyes), optic darkspace beneath RPE layer in serous detachment of RPE layer (19 eyes), quickly decreased high backscattering region under RPE layer in hemorrhagic detachment of RPE layer (11 eyes), slight to moderate backscattering region between RPE layer in fibrovascular detachment of RPE layer (10 eyes), and detachment of neurepithelial layer from RPE layer with the optic darkspace between the layers in detachment of neurepithelial layer (45 eyes) were observed.ConclusionsThe images of OCT for the common diseases which could lead to submacular choroidal neovascularization may be divided into 6 types. Analyzing the characteristics of images of OCT is helpful in differential diagnosis and treatment of CNV. (Chin J Ocul Fundus Dis, 2005,21:69-73)
