Objective To investigate the relationship between the level of testosterone and estradiol in serum and central serous chorioretinopathy (CSC).Methods The clinical data of 200 patients with active phase CSC who diagnosed by clinical manifestation, examination of fundus and fluorescence fundus angiography (FFA), were retrospectively analyzed. Two hundreds healthy people were collected as a control group. The blood of ulnar vein was collected and the method of magnetic homogeneous enzyme immunoassay was used to detect the level of testosterone and estradiol in serum of two groups. The results were analyzed statistically by t test.Results The values of testosterone and estradiol of male were all higher in CSC group than that in control group，the differences were statistical significance（t=2.804，2.913；P=0.010，0.008）；it was also higher in female（t=2.078，2.807；P=0.049，0.010）. The value of testosterone/estradiol of male was higher than that of female in CSC group，the difference was statistical significance(t=2.231，P=0.046).Conclusions The level of testosterone and estradiol in serum of CSC group increased obviously, especially the value of testosterone/estradiol. The increase of estradiol and testosterone/estradiol may be an etiological factor of CSC.
Objective To analyze the etiology of central exudative chorioretinopathy（CEC）. Methods A total of 32 CEC patients were asked the medical history, and underwent examination of purified protein derivative（PPD）test, chest Xray, blood routine test, Creactive protein, erythrocyte sedimentation rate, TORCH test and rapid plasma regain cirde card test, to determine the possible causes of CEC. Results Thirty-two patients didnprime;t have the history of tuberculosis, and no evidence of systemic active tuberculosis was found in the chest X-ray examination. the results of PPD test showed the positive rate was 37.5％. The disease condition of paitents with positive result of PPD test was stable or was alleviated after anti-tuberculosis therapy. All the results in IgM of TORCH test and rapid plasma regain cirde card test were negative. Conclusion No infectious factors related to CEC was found, thus choroidal neovascularization of CEC might be idiopathic.
Objective To evaluate the clinical features and treatment outcomes of ocular posterior segment syphilis. Methods The clinical data of 24 patients with active ocular syphilis were retrospectively reviewed. The diagnosis was made first in eye clinic，and verified by treponema pallidum particle agglutination (TPPA) and rapid plasma reagin (RPR). The patients, 17 males and 7 females, aged from 30 to 63 years with an average of 47.6 years. The duration of symptoms ranged from 3 days to 2 years with an average of 5.8 months (le;1 month, 7 cases; 1-3 month, 5 cases; 3-6 months, 5 cases; ＞6 months, 7 cases). There were 18 bilateral cases and 6 unilateral cases. The result of human immunodeficiency virus (HIV) test was negative for all cases. Twenty-three patients received systemic penicillin therapy and 1 patient was treated with oral erythromycin due to penicillin allergy. Before treatment, the mean visual acuity was 0.17plusmn;0.19，the mean titer of RPR was 1:84。The follow-up period was half a year. Results The major ocular manifestations included bilateral (16 cases) or unilateral (1 case) chorioretinitis, unilateral retinal vasculitis (2 cases), unilateral neuroretinitis (2 cases), and bilateral (2 cases) or unilateral (1 case) optic neuritis. The mean follow-up visual acuity was 0.60plusmn;0.29，the mean follow-up titer of RPR was1:18.8. Some patients had got the diagnosis and prompt treatment at the early stage of the disease and their visual acuity recoveried very well. Conclusions The major manifestion of ocular posterior segment syphilis is chorioretinitis. It is important to consider the possibility of syphilis when patients have inflammation of posterior segment. Prompt serology examination and penicillin treatment are the keys to cure ocular syphilis.
Objective To observe the findings of indocyanine green angiography(ICGA) and fundus fluorescein angiography (FFA) of the patients with multifocal posterior pigment epitheliopathy(MPPE). Methods ICGA and FFA were performed in 6 cases(7 eyes)of MPPE and the findings were analysed and compared between these examinations. Results Five cases(5 eyes)were found to be in the active stage of the disease under FFA,and among them 4 eyes(80%)showed delayed choroidal perfusion at the early stage of ICGA.During the active stage of the disease,ICGA showed leakage relative to FFA leakage,and there were diffuse hyperfluorescence around the points of leakages as well as in the posterior pole of ocular fundus．In convulescence,although FFA revealed no obvious leakage,ICGA still denoted the presence of leakages. Conclusions MPPE was considered to be the more serious type of central serous chorioretinopathy showing the same but more extensive ICGA abnormality. (Chin J Ocul Fundus Dis,2000，16：6-8)
