Context:The preferential occurrence of idiopathic central serous chorioretinopathy (ICSC) in males with a typical Type A personality and behavior and a relative absence in females is a possible indicator towards the role of serum cortisol and /or the male sex hormone testosterone. Aims:To study levels of cortisol and testosterone in ICSC. Settings and Design:Case-control study in a tertiary care teaching hospital. Materials and Methods:The study was conducted on 23 cases of ICSC. Twelve patients with unilateral sudden painless loss of vision of less than one month duration served as controls. Serum cortisol and testosterone levels at 8.00 a.m. were estimated by radioimmunoassay in both groups. Statistical analysis used:Statistical analysis was done using SPSS 13.0 software. Independent Sample t-test was applied to analyze statistical significance between the two groups. Results:Mean age of patients with ICSC was 37.1 ± 9.7 years and 96% of the patients were males. Mean serum cortisol levels were significantly higher ( P=0.002) in patients with ICSC i.e., 495.02 ± 169.47 nano moles/liter (nmol/L) as compared to controls i.e., 362.25 ± 51.54 nmol/L. Mean serum testosterone levels were 3.85 ± 1.81 nano grams/ml (ngm/ml) and 4.23 ± 1.89 ngm/ml in cases and controls respectively and the difference was not statistically significant ( P=0.58). Conclusions:ICSC is associated with elevated 8.00 a.m. serum cortisol levels. However, mean serum testosterone levels in both patients of ICSC and controls were within normal range. 相似文献

Background: A prospective evaluation of the pattern of fundus autofluorescence in cases of acute versus chronic central serous chorioretinopathy (CSR). Methods: A prospective, cross‐sectional, single‐centre investigation was performed using three diagnostic techniques, namely, fundus autofluorescence, optical coherence tomography and fundus fluorescein angiography to evaluate a sample of patients (n = 42 eyes) with both acute (n = 25 eyes) and chronic (n = 17 eyes) CSR. Results: Hypoautofluoresecence was found in 80 per cent (20 eyes) and 88.2 per cent (15 eyes) of eyes in the acute and chronic central serous chorioretinopathy groups, respectively, corresponding to the leakage points depicted by fluorescein angiography. Hypoautofluoresence corresponding to the areas of subretinal fluid accumulation was seen in 92 per cent (23 eyes) and 82.3 per cent (14 eyes) of the acute and chronic central serous chorioretinopathy groups, respectively. In two eyes (11.6 per cent) with chronic CSR, hyperautofluorescent changes were noted at the previous leakage points. In the acute CSR group, speckled hyperautofluorescence was detected in nine eyes (36 per cent) after the resolution of subretinal fluid. In the chronic CSR group, simultaneous speckled hyperautofluorescence was detected in the previous areas of subretinal fluid accumulation in 12 eyes (70.5 per cent). Conclusion: Fundus autofluorescence imaging delineates endogenous fluorescence derived mainly from lipofuscin within the retinal pigment epithelium (RPE) layer and therefore permits evaluation of functional alterations in the RPE in numerous retinal diseases. Data from fundus autofluorescence revealed distinctive findings in acute and chronic CSR. Fundus autofluorescence imaging may be used as a supplementary diagnostic tool for identifying patients with CSR and differentiation may be made between acute and chronic cases. 相似文献

BACKGROUND: This study aimed to investigate the long-term effects of central serous chorioretinopathy (CSCR) on macular function. METHODS: Sixty-two eyes of 31 patients were included in this study. All patients were diagnosed with unilateral CSCR at the Retina Unit of the Ophthalmology Department, Trakya University Medical Faculty, and had a post-attack bilateral visual acuity of 6/6 and a follow-up period of a minimum of 6 months. Visual function was assessed using the Amsler grid, 40-hue colour discrimination test, visual field examination by means of Octopus automatic perimeter and Cambridge contrast sensitivity tests. RESULTS: Of the 31 patients, 71% were men and 29% were women, with a mean age of 39.3 +/- 7.6 years. The patients had a mean follow-up period of 50.6 +/- 40.5 months after the acute attack. Metamorphopsia was observed in 67.7% of the cases with CSCR. A colour discrimination defect was found in 48.4% of the CSCR eyes and in 54.8% of the fellow eyes. As compared with the fellow eyes, the mean deviation in the central 10 degrees of visual field was significantly higher (t = 2.9, P = 0.007) and the mean contrast sensitivity score was significantly lower (t = -3.2, P = 0.004) in the CSCR eyes. DISCUSSION: Patients with unilateral CSCR were observed to have long-term bilateral colour discrimination defects, and eyes with clinical CSCR were determined to have central relative scotoma and loss of contrast sensitivity. 相似文献

AIM: To examine eplerenone (Inspra, Pfizer), a mineralocorticoid receptor antagonist, as a treatment option for chronic central serous chorioretinopathy (CSCR).
METHODS: A retrospective consecutive case series was conducted for patients receiving oral eplerenone for chronic CSCR. At baseline and each follow-up visit, spectral domain optical coherence tomography (SD-OCT) imaging was performed, including manual measurements of the height and diameter size of subretinal fluid. The primary outcome measure was the reduction in subretinal fluid following initiation of therapy.
RESULTS: A total of 17 eyes of 13 patients treated with 25 and 50 mg of oral eplerenone per day were identified. Subretinal fluid (SRF) decreased over time following eplerenone therapy (P= 0.007 and P = 0.002, diameter and height respectively). Maximum SRF height decreased from a mean of 131.5 μm at baseline to 15.3 μm at day 181+. SRF diameter decreased from an average of 2174.4 μm at baseline to 46.9 μm at day 181+. LogMAR visual acuity improved from 0.42 (Snellen equivalent: 20/53) at baseline to 0.29 (Snellen equivalent: 20/39) at day 181+ (P = 0.024). Central subfield thickness (CST) decreased from 339.5 μm at baseline to 270.3 μm at day 181+ (P = 0.029).
CONCLUSION: Eplerenone therapy resulted in significant anatomic and visual improvements in eyes with chronic CSCR. 相似文献

Purpose: The reporting of the occurrence of central serous chorioretinopathy in a patient with congenital optic pits. Methods: A 31-year-old man complained of blurred vision in the right eye for 1 week. He had a visual acuity of 20/25 in the right eye. He underwent ophthalmoscopy and fluorescein angiography. Results: Ophthalmoscopy revealed serous detachment of macula with its margin not adjacent to the margin of optic disc. Fluorescein angiography showed a typical ink blot appearance of dye leakage. Conclusions: Central serous chorioretinoapthy can occur in the patient with congenital optic pits. Detailed ophthalmoscopic and fluorescein angiographic studies are necessary to establish the diagnosis of optic pits associated with macular detachment. Various mechanisms have been reported to explain the serous macular detachment in patients with optic pits including vitreous and cerebrospinal fluid leakage through the optic pit and from there into the subretinal space. The present case further denotes that central serous chorioretinopathy in the presence of optic pits can be due to leakage from the retinal pigment epithelium. 相似文献

Central serous chorioretinopathy (CSCR) is one of the most common chorioretinal pathologies affecting middle-aged men worldwide. Although it has a self-limited course, a significant number of patients suffer from chronic and recurrent episodes. This often leaves the patient with various degrees of visual impairment. The situation is further aggravated by the fact that it is one of the most common conditions to be misdiagnosed. Because of overlapping features with other diseases or the atypical presentation of the disease itself, CSCR is a great mimicker and is one of the commonest causes of referral. We describe some of the conditions which can masquerade as CSCR. 相似文献
