Axial length in unilateral idiopathic central serous chorioretinopathy

AIM： To evaluate the axial length（AXL） in unilateral idiopathic central serous chorioretinopathy（CSC）.·METHODS： This retrospective case-control study was comprised of a consecutive case series of 35 patients with acute unilateral idiopathic CSC, and age- and sex-matched 50 control eyes. AXL of both eyes of unilateral CSC patients and the control eyes were investigated.AXL was measured by ultrasonic biometry, and the adjusted AXL was calculated for CSC eyes as measured AXL plus differences of foveal thickness between CSC and normal fellow eyes in millimeters. The main outcome measures were comparison of AXL between CSC, fellow and control eyes.· RESULTS： The mean age of 35 CSC patients was45.5y, and 31 males were included. The adjusted AXL of CSC eyes was 23.52 mm, and the AXL of fellow eyes was23.46 mm, and of control eyes 23.94 mm. The AXL of both CSC and fellow eyes were significantly shorter than control eyes（CSC vs control, P =0.044; fellow vs control, P =0.026）. There was no statistically significant difference in AXL between CSC and fellow eyes.·CONCLUSION： In unilateral idiopathic CSC, the AXL of CSC and fellow eyes are shorter than that of control eyes. Short AXL may be related with choroidal circulation abnormality in CSC.

Angiographic characteristics of central serous chorioretinopathy in an Egyptian population

· AIM: To describe and analyze the demographic characteristics and to determine the angiographic features of acute central serous chorioretinopathy(CSCR) in an Egyptian population. ·METHODS: A series of consecutive patients presenting with acute idiopathic CSCR to Mansoura Ophthalmology Center Mansoura University who underwent fluorescein angiography (FA) within a 3 -year -period (between January 1, 2007 and December 31, 2009) was retrospectively studied. Patient demographics and angiographic features were studied. Results were compared to those of other Western and Asian populations. ·RESULTS: Fluorescein angiograms of 86 patients were analyzed. 91% were males. The age range of patients was 24 -49 years, with a mean age of (38±6) years. The right eye was the presenting eye in 47% of patients. Eighty seven percent of eyes showed delayed choroidal filling. Thirty -five percent of patients had more than one point of leakage. The macula was the most common site of fluorescein leakage seen in 79% of patients. Peripheral leakage was seen in 14% of patients while peripapillary leakage was seen in 12% of patients. The inkblot leakage pattern was found in 53% of patients. The presenting eye had RPE atrophic changes in 84% of cases. The other eye was assessed in 44 patients (51%). Fifty-five percent of them had signs of RPE atrophic changes. ·CONCLUSION: In the Egyptian population, CSCR is seen at younger age with higher male -to -female ratio and more frequent smokestack leaks than other populations. Despite younger age group, this series of patient showed higher frequency of bilateral and multifocal disease compared to other studies. Roles of psychological stress and choroidal ischemia in pathogenesis of CSCR need further evaluation. ·
