  • 后部葡萄膜恶性黑色素瘤-----流行病学及临床病理学特征

    葡萄膜恶性黑色素瘤是成年人最常见的原发性眼内恶性肿瘤,是致死的最主要原发性眼内疾病。该瘤主要发生于睫状体和脉络膜,称为后部葡萄膜恶性黑色素瘤。近20年对该瘤进行了大量临床与基础研究,有了许多新认识。 (中华眼底病杂志,1997,13:57-59)

  • Histopathological studies on the ischemic central retinal vein occlusion in human eyes

    Objective To observe the histopathological changes in human eyes with ischemic central retinal vein occlusion (CRVO), and to provide objective basis for effective methods of prevention and treatment for (CRVO). Methods Histopathological analysis was performed on the samples of 11 eyes in 11 patients with ischemic CRVO. The changes of central retinal veins (CRV) and central retinal arteries (CRA) wereobserved. Results The lumen of CRV became narrow when passed through the lamina cribrosa in 11 eyes, in which organized thrombus was found in the lamina cribrosa region and post lamina cribrosa region in 5 eyes, and organized thrombus re-unobstructed channels, endothelial proliferation and narrow lumen were found in 6 eyes. Arteriosclerosis of the CRA was observed in all of the 11 eyes with thick wall of the artery and narrow lumen. Proliferation of endothelium of wall of CRA and narrow lumen in the lamina cribrosa region was found in 2 eyes and no thrombus was found at the lamina cribrosa level. Conclusion During the course of ischemic CRVO, thrombus occurs in CRV at the level of lamina cribrosa. The prognosis of CRVO may lie on the time and degree the thrombosis re-opens. The mechanism of CRVO is that CRV is pressed in the narrow interspace of scleral channels of lamina cribrosa. (Chin J Ocul Fundus Dis, 2007, 23: 163-165)

  • ENZYMATIC HISTOCHEMICAL STUDIES ON RETINAL VESSELS

    The activities and distributions of succinate dehydrogenase(SDH),malic dehydrogenase(MDH),lactic dehydrogenase(LDH),acid phosphatase(ACP) and alkaline phosphatase(AKP) in retinal vessels were studied and observed with enzymatic histochemical techniques. The retinal vessels showed a b LDH activity, moderate SDH and MDH activity. The dehydrogenase activity described above was evenly and equally distributed in the microvasculature between arterioles and venules, and was the best in arteries. AKP showed predominant activity in the endothelial cells of capillaries and arterioles which were stained bly. No activity for ACP observed in the retinal vessels. The observations above indicate that the retinal vessels are metabolically active and have a great capacity for glycolysis. (Chin J Ocul Fundus Dis,1992,8:6-9)

  • Applying wide-angle fundus imaging modalities to improve the diagnosis and treatment of ocular fundus diseases

    The hallmark of the recent latest advances in diagnostic fundus imaging technology is combination of complex hierarchical levels and depths, as well as wide-angle imaging, ultra-wide imaging. The clinical application of wide-angle and ultra-wide imaging, not only can reevaluate the role of the peripheral retina, the classification types and treatment modalities of central retinal vein occlusion, and enhance the reliability of diabetic retinopathy screening, improve the classification and therapeutic decision of diabetic retinopathy, and but also can help guide and improve laser photocoagulation. However we must clearly recognize that the dominant role of ophthalmologists in the diagnosis of ocular fundus diseases cannot be replaced by any advanced fundus imaging technology including wide-angle imaging. We emphasize to use the three factors of cognitive performance (technology, knowledge and thinking) to improve the diagnosis of ocular fundus diseases in China.

  • Clinical research of macular branch retinal vein occlusion and surveying of the area of foveal avascular zone

    Objective To observe the clinical characteristics of patients with macular branch retinal vein occlusion (MBRVO) and the changes of the area of foveal avascular zone (FAZ).Methods The data of 69 eyes of 69 patients with MBRVO, who had been diagnosed by ophthalmoscopy, slit-lamp examination and fluoresce in angiography, were retrospectively studied. The relationship of locations between artery and vein on the obstructive site, and the characteristics of fundus pictures, retinal vasculature changes and the complications were analyzed. In 69 patients with MBRVO, 36 had the course of disease for more than 3-6 months, of whom the area of FAZ was compared with that of 30 healthy people.Results In 69 patients, superior MBRVO occurred in 45 eyes (65.22%), and inferior MBRVO occurred in 24 eyes (34.78%). Most of the arteries were anterior to the veins at the obstructive site. Four clinical types of MBRVO were found, and the main complication was macular edema. There was a significant difference in area of FAZ between patients with MBRVO and healthy people (P<0.05). Conclusion There are several clinical characteristics of MBRVO with different manifestations. The area of FAZ of patients with MBRVO is obviously lager than that of the healthy people.
