Objective To analyze the characteristics of images of fundus fluorescein angiography (FFA) in patients with central serous chorioretinopathy (CSC).Methods We observed the positions of leakage spots of retinal pigment epithelium (RPE) and analyzed their characteristics in 598 CSC patients. The ages, visual acuty, detachment areas of sensory retina, and leakage patterns of RPE were recorded and the correlation of them were analyzed. Results The leakage concentrated in the posterior pole, which occurred more frequently in the superior quadrant, nosal quadrant, and near fovea regions than in the inferior quadrant,temporal quadrant, and far regions from fovea, respectively (chi;2=67.13,20.93, 212.715; Plt;0.01).We found that there were relations between the ages of patients and the patterns of the leakage. A total of 35 patients (54.7% out of 64) at the age of ge;50 had small leakage; 82 patients (53.2% out of 154) at the age of 35-39 had diffusing leakage. Smaller retinal detachment in patients with multiple serous leakage and bigger retinal detachment area in patients with single serous leakage were found; no statistical significance was found (F=1.925,Pgt;0.05). There was negative correlation between the visual acuity and the detachment area in CSC patients (t=-0.335,Plt;0.01), and there was no correlation between the visual acuity and the distances from the leakage spots to the fovea (t=-0.029, -0.145;Pgt;0.05).Conclusion The leakages occurs in various regions whose difference is significant; the patterns of leakage are related to the ages; there is no relation between the serous retinal detachment area and the number of the leakage.
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)
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 compare the characteristics of fundus angiograms of central serous chorioretinopathy (CSC) with exudative agerelated macular degeneration (AMD) in patients more than 45. Methods The colorized photographs of ocular fundus, and results of fundus fluorescein angiography (FFA) and indocyanine green angiography (ICGA) of 32 patients (39 eyes) with CSC and 20 patients (22 eyes) with exudative AMD more than 45 were collected and analyzed retrospectively. Results In 39 eyes with CSC, the results of FFA revealed classic CSC in 11 (28.2％) and diffuse retinal pigment epitheliopathy (DRPE) in 28 (71.8％); the results of ICGA showed localized choroidal delayed filling associated with dilated vessels in 39 (100％) in the early phase, choroidal hyperpermeability in 39 (100％), identifiable hyperfluorescence of leakage from RPE in 16 (41.0％) was observed in the middle phase, and a distinctive silhouetting of the larger choroidal vessels in 5 (12.8％) was detected in the late phase. In 22 eyes with exudative AMD without evident hemorrage, the results of ICGA exhibited focal CNV in 13 (59.1％), plaque CNV in 8 (36.4%), and combination CNV in 1 (4.5%)；choroidal delayed filling around macular region vicariously was found in 5 (22.7％) in the early phase, choroidal hyperpermeability was not observed in the middle phase and silhouetting of the larger choroidal vessels was not showed in the late phase. Conclusions The differences of the ICGA features between CSC and exudative AMD in patients more than 45 include focal or multifocal hyperfluorescence of leakage from RPE, multifocal choroidal hyperpermeability in the middle phase, silhouetting of the larger choroidal vessels in the late phase, and no focal or plaque CNV.
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 evaluate the effects of traspupillary thermotherapy (TTT) for the treatment of central exudative chorioretinopathy (CEC). Methods Twelve eyes of 12 patients who suffered from CEC were treated by using a diode laser at 810 nm. A variable spot size of 0.5mm-2.0mm was used depending on the size of choroidal neovascularization (CNV).The treatment was initiated in one spot for 55 to 60 seconds duration at a power range between 200-350 mW, and the treated area revealed no visible color change to a light-gray appearance. Preoperative and postoperative fluorescein angiography (FFA) and indocyanine green angiography (ICGA) were performed in 10 of the 12 eyes. Results The visual acuity in all eyes was improved to different degree over a period of 3-10 months. Five or more lines improvement measured by Snellen chart in visual acuity was found after the treatment in 4 eyes, three to five lines in 5 eyes and one to two lines in 3 eyes. All eyes demonstrated decreased or vanished exudation in FFA. CNV disappeared or decreaced in 8 eyes and remained nochange in 2 eyes in ICGA. Conclusion TTT is obviously effective in treating CEC.

Objective To asses the potential of a new imaging technique,opticl coherence tomography(OCT),for diagnosis and monitoring of central serous choroidoretinopathy(CSC). Methods Thirty cases (32eyes) with CSC were examined by ophthalmoscopy, fundus fluorescein angiography and OCT. Some patients were monitored by OCT. Results Among images of OCT in 32 eyes with CSC, 27 eyes showed serous neurosensory detachement,2 eyes appeared retinal pigment epithelial detachement and 3 eyes combined neurosensory detachement with pigment epithelial detachement.Monitoring images of OCT in ll eyes revealed absorption of serous fluid and decrease of neurosensory detachment． Conclusions OCT is potentially useful as a new and noninvasive diagnostic technique for quantitative examination of patients with CSC and objectively monitoring the clinical course of the serous retinal detachement in this disease.
