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 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 compare difference of the cross-sectional pathological imaging and quantitative measurement of central serous chorioretinopathy (CSC) between time- and fourier-domain optical coherence tomography (OCT). Methods Consecutive 26 patients (26 eyes) with unilaterial CSC were subsumed. Bilateral eyes of all the patients underwent time- and fourier-domain OCT. Horizontal and vertical line scanning and radial six-line scanning protocols were used for timedomain OCT examination; horizontal and vertical high resolution five-line scanning and macular cube scanning protocols were used for fourier-domain OCT examination. The characteristics of OCT images, retinal segmentation and the quantitative measurement were compared between these two methods. Results Fourier-domain OCT could yield the three-dimensional images of surface of inner limiting membrane (ILM) and RPE. The band of external limiting membrane (ELM) of normal subjects and CSC patients, and the inner segment and outer segment (IS/OS) of normal subjects could be clearly shown by fourier-domain OCT. However, the band of IS/OS disappeared in 65.4% of the CSC patients. The outer boundary of retina was defined in front of the retinal pigmental epithelia (RPE) by fourier-domain OCT. The foveal thickness of normal subjects and CSC patients was (180.50plusmn;12.69) and (158.41plusmn;34.20) mu;m, respevtively. The height of detachment of neural epithelial layer was (245.84plusmn;154.61) mu;m measured by fourier-domain OCT. The band of IS/OS of normal subjects could be clearly shown by time-domain OCT. However, the band of IS/OS disappeared in 73.4% of the CSC patients, which showed no difference with fourier-domain OCT (Z=-0.108, P=0.914). The outer boundary of retina was defined in front of the IS/OS band by OCT. The foveal thickness of normal subjects was (141.16plusmn;12.75) mu;m, which was thinner than that measured by fourier-domain OCT (t=20.671，P=0.000). The foveal thickness and the height of detachment of neural epithelial layer was (146.40plusmn;36.28) mu;m and (240.32plusmn;156.82) mu;m measured by time-domain OCT, respectively, which showed no significant difference with which measured by fourier-domain OCT (t value was from 0.026 to 1.517, P value was from 0.144 to 0.980). Conclusions Fourier-domain OCT yields better visualization of intraretinal layers and more accurate definition of outer boundary of retina than time-domain OCT. Thus the measurements by fourier-domain OCT were more accurate. Moreover, three-dimensional images of CSC shown by fourier-domain OCT enable the comprehensive observation of pathological morphology and location.
Objective To evaluate the morphological changes of retinal neuroepithelium of central serous chorioretinopathy (CSC) by Fourierdomain optical coherence tomography(FD-OCT). Methods FD-OCT scan was performed on 92 eyes of 88 patients with CSC. The CSC diagnosis was established by international visual acuity chart, slit-lamp microscope, direct/indirect ophthalmoscope, fundus fluorescein angiography (FFA) and indocyanine green angiography (ICGA). 6 mm horizontal line OCT scan was performed utilizing the infrared light emitted by diode, the scan depth was 2 mm with a 6 mmtimes;6 mm transverse area. The vertical and horizontal resolution was 5 mu;m and 18 mu;m respectively. The scan mode was 512times;128. Results The uplift of retinal neuroepithelium, separation or abnormal band of retinal pigment epithelial (RPE) were found in all eyes. There were 83 eyes (90.22%) of pigment epithelial detachment (PED), 68 eyes (73.91%) of nodular protruding of RPE, 5 eyes (5.43%) of localized RPE defects in the PED lesion, 36 eyes (39.14%) of dust-like reflects in the subretinal space and 59 eyes (64.14%) of granular deposits in the subretinal space. Conclusion Fourier-domain OCT scans can detect detailed morphologic changes in the retina of CSC patients.
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.
