Objective To investigate the clinical characteristic of ocular fundus complications in systemic lupus erythematosus (SLE). Methods In 25 cases of SLE with the ocular fundus complications, the ocular fundus, the other ocular tissues, general lesions，and antinuclear antibody (ANA ), anti-double-stranded DNA（anti-dsDNA）, complement 3 (C3), complement 4 (C4)and erythrocyte sedimentation rate(ESR) were analyzed retrospectively. Results In the 25 cases, “classic” SLE retinopathy in 15 (25 eyes), retinal vein occlusion (RVO) in 9 (12 eyes), RVO combined with retinal arter y occlusion in 1 (2 eyes), exudative retinal detachment in 1 (2 eyes), vitreous hemorrhage combined with neovascular glaucoma in 1 (1 eye), and optic discedem a except RVO in 3 (6 eyes) were found. Nine cases accompanied with other ocular signs and 21 with general lesions. Positive ANA and anti-dsDNA and elevated ESR in all of the patients, decreasing C3 in 19, and C4in 17 were found.Conclusions SLE can cause serious ocular fundus complications accompanied with other ocular signs. Regular ophthalmic examination should be performed on the patients with SLE to detect and treat the ocular complications promptly. (Chin J Ocul Fundus Dis，2004，20：206-208)
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)
Objective To observe the serum lipid level of patients with branch retinal vein occlusion (BRVO). Methods A total of 71 BRVO patients (BRVO group) were enrolled in this study. The patients included 31 males and 40 females, with an average age of (52.75plusmn;10.2) years. All the patients were examined for visual acuity, slit lamp ophthalmoscopy combine with preset lens, fundus color photography and fundus fluorescein angiography (FFA) examination. Seventy-two age and sex matched normal subjects were enrolled in this study as control group. The subjects included 32 males and 40 females, with an average age of (53.10plusmn;9.5) years. The BRVO and control group were divided into four subgroup which including age with ＜40 years, 40-49 years, 50-59 years and ge;60 years. The plasma cholesterol and triglyceride level of BRVO group, control group, and age subgroups of BRVO and control group were comparatively analyzed. Results The average plasma cholesterol levels were (4.529plusmn;0.100) and (4.274plusmn;0.106) mmol/L in BRVO and control group, respectively. There was no difference between two groups (t=-1.738，P＞0.05). The average triglyceride levels were (1.500plusmn;0.129) and (1.319plusmn;0.095) mmol/L in BRVO and control group, respectively. There was no difference between two groups (t=-1.135，P＞0.05). There was no difference of average plasma cholesterol (t=-1.755, 1.850, -1.892, -0.507) and triglyceride (t=0.846, -0.074, -1.288, -1.887) level in age subgroups of BRVO and control subgroup (P＞0.05). Conclusion There is no significant difference of serum lipid level between BRVO patients and controls.
Objective To investigate the relationship among central retinal vein occlusion (CRVO), major systemic diseases, ocular local diseases and related risk factors in Chinese population. Methods Seventeen-six patients with CRVO diagnosed by fundus fluorescein angiography (FFA) without any medical treatment were in CRVO group. Another 76 patients without CRVO or any vascular diseases of ocular fundus were in the control group who were matched with the ones in CRVO group to a one-to-one partnership according to the age and gender. The 2 groups were subdivided into le;45 years old (25 patients, 32.9%) and gt;45 years old (51 patients, 67.1%) subgroups according to the age, and 2 ischemia and non-ischema subgroups according to the results of FFA, respectively. The blood lipid, blood pressure, and fasting blood glucose were measured. The systematic diseases, ocular local diseases and the related risk factors were statistically analyzed and compared. Results The incidence of hypertension and hyperlipemia in CRVO group were significantly higher than that in the control group (Plt;0.001,P=0.001). There was no significant difference of cardiovascular diseases, cerebrovascular diseases, open-angle glaucoma, and smoking and drinking between the two groups(Pgt;0.05). In le;45 years old subgroups, there was no significant difference of each examination target between CRVO and control group(Pgt;0.05). In ischemia subgroups, except for the hypertension and hyperlipemia, the incidence of diabetes mellitus was obviously higher in CRVO group than that in the control group (hyperlipidemia:P=0.031; diabetes mellitus:P=0.024; diabetes mellitus: Plt;0.001). Conclusion Hypertension and hyperlipidemia are the systematic factors in Chinese population with occurrence of CRVO. In addition, diabetes mellitus is associated with ischemic CRVO. Timely diagnosis and treatment of the systematic diseases is important to the prevention and treatment for CRVO. (Chin J Ocul Fundus Dis, 2007, 23:159-162)
