  • 视网膜色素变性的组织病理学改变

    视网膜色素变性患者的眼前节即结膜、角膜、前房角和虹膜无病理改变,而病理改变是在眼后部,包括晶状体、玻璃体、视网膜、脉络膜、视乳头和视神经的异常,主要的病变发生在视网 膜。在早期病例中,梗网膜的感光细胞发生变性和死亡,故病人表现夜盲。中心视力下降和视野缩窄。晚期病例,视网膜感觉层退变坏死,胶质细胞增生,视网膜瘢痕化,从而导致失明.视网膜色素上皮细胞继发性变性、消失,或局部增生,色素细胞迁移到赤道附近血管交叉的周围,形成骨针样色素沉着的典型眼底改变。 (中华眼底病杂志,1994,10:63-66)

  • 视网膜疾病与细胞凋亡及caspases研究概况

    研究表明,许多视网膜疾病与细胞凋亡有关。细胞发生凋亡的过程中,蛋白水解酶,尤其是caspases家族蛋白酶在凋亡信号传导过程中起着关键性的作用。现将视网膜疾病如视网膜脱离、视网膜母细胞瘤、视网膜色素变性、视网膜缺血性损伤和老年黄斑变性与细胞凋亡及caspases的研究概况综述如下。 (中华眼底病杂志,2001,17:79-81)

  • 脉络膜黑色素瘤经瞳孔温热疗法研究概况

    近十年来,国外许多眼科中心先后将经瞳孔温热疗法用于脉络膜黑色素瘤的治疗 。现有临床资料表明,该方法治疗小脉络膜黑色素瘤具有疗效可靠、操作简单和并发症少等优点。国内尚未见有这方面的报道。现将脉络膜黑色素瘤经瞳孔温热疗法治疗的治疗原理、 适应证、治疗方法、并发症及其处理等做一综述,以供临床参考。 (中华眼底病杂志,2001,17:327-329)

  • 人视网膜激光光凝后的组织病理学研究概况

    激光光凝术已普遍用于治疗眼底疾病,对光凝术后视网膜的组织病理学研究为激光的临床应用提供了重要的参考。它能帮助我们正确地应用光凝技术,达到治疗目的和减少副作用。有关人视网膜的资料很少,但很重要,因此本文综述了不同种类、不同时期、不同部位、不同程度激光光凝人视网膜后的组织病理学变化,以及光凝术的并发症的病理学表现。

  • HISTOPATHOLOGIC OBSERVATION OF THE PHOTORECEPTORS IN RET1NITIS PIGMENTOSA

    PURPOSE:Investigating on histopathologic changes of the photoreceptors in retinitis pigmentosa. METHODS:Observation of the photoreceptors of retinitis pigmentosa in 11 eyes among 9 cases using light and electron microscope. RESULTS: The pathologic changes of the photoreceptors were found to be mostly marded at the equatorial area and less at the periphery,posterior pole and macular region of the retina. In relatively early cases,degeneration and shortening of outer segments,reduction or loss of connecting cilia,stubby inner segments and swollen mitochondria Were the predominant findings. In advanced cases,the inner and outer segments and connecting cilia were diminished with reduction of nuclei in number and disarangement,cellular degeneration and disorganization. The outer limiting membrane adhered to RPE or Bruch membrane. The spaces left over by the above pathologic changes were replaced by the displaced Muuml;ller cells and their hypertrophic processes. Also there were degeneration of the RPE cells,and some of them might migrate into the retina. CONCLUSION:Obvious invasions of pathologic processes in photoreceptors of the retina did present in patients with retinitis pigmentosa. (Chin J Ocul Fundus Dis,1996,12:160-162)

  • ALLOSCLERA TRANSPLANT FOR EYELID RECONSTRUCTION

    OBJECTIVE: To study the clinical effects of allosclera transplant for eyelid reconstruction. METHODS: From May 1986 to January 2001, 45 patients who suffered from partial eyelid defect underwent the allosclera transplant for eyelid reconstruction, There were 31 cases of male and 14 cases of female, 18 cases of the upper eyelid and 27 cases of the lower eyelid, among them, 22 cases were caused by eyelid trauma and 23 cases by eyelid tumor. The length of eyelid defect were less than 1/2 of the whole eyelid. The morphology and function of the eyelid and complications were observed after operation. RESULTS: All 45 cases were followed up for 11 to 38 months, 19.7 months on average. The eyelid morphology and mobility restored well and there was no influence on visual function. CONCLUSION: The xenosclera is an ideal material for eyelid reconstruction.

  • Clinical histopathological and misdiagnostic analysis of 359 cases of intraocular tumors

    Objective To probe the clinical character,the histopathological classification and misdiagnoses of intraocular tumors. Methods The clinical and pathological data of 359 patients with intraocular tumor diagnosed clinically between 1980~2000 were retrospectively analyzed. Results There were 300 cases of malignant tumor and 23 cases of benign tumor respectively. Non-oncologic malady and benign tumor misdiagnosed as tumor or malignant tumor were 40 cases. The two leading malignant tumors were retinoblastoma and melanoma. Conclusion The clinical and pathological analysis of intraocular tumor is beneficial to the correct clinical diagnosis and treatment. (Chin J Ocul Fundus Dis,2002,18:28-30)

  • The clinico-pathological analysis of choroidal metastatic carcinom aarising from lung carcinoma

    Objective To observe the clinical and pathological characteristics of choroidal metastatic carcinoma from lung carcinoma.Methods The clinical and pathological data of 6 patients with choroidal metastatic carcinoma from lung carcinima were analysed retrospectively.Results All the 6 patients had severe visual impairment, including 3 with severe ophthalmalgia. Flat neoplasm were seen in the posterior pole of the eyes in all the 6 patients and retinal detachment were found in 5 patients. Fundus fluorescein angiography (FFA) examination had been performed on 1 patient and blocked fluorescence and hyperfluorescence were seen in the lesion with pinpoint fluorescein leakage loop around it. CT examination had been performed on 3 patients and the shadow of flat homogenous tumor was seen. MRI examination had been performed on 1 patient and high signal intensit ies on T1W and low signal intensities on T2W were found. In all the 6 patients with primary lung carcinoma, 5 were diagnosed with adenocarcinoma and 1 with cellule carcinoma through pathological examination, and 5 patients were diagnosed with choroidal metastatic carcinoma from adenocarcinoma and 1 with choroidal metastatic carcinoma from cellule carcinoma through pathological examination.Conclusion Rapid visual acuity decrease, severe ophthalmalgia, flat neoplasm in ocular fundus and secondary retinal detachment are the main clinical characteristics of the choroidal metastatic carcinoma from lung carcinoma. Most histopathologica l manifestations of the metastatic carcinoma like that of the primary focus, and adenocarninoma is the most common histoclassification. (Chin J Ocul Fundus Dis,2003,19:333-404)
