ABSTRACT
Objective To compare the differences of optic nerve head (ONH) parameters and the thickness of circumpapillary retinal nerve fiber layer (CP-RNFL) between acute Vogt-Koyanagi-Harada syndrome (VKH) and acute central serous chorioretinopathy (CSC) patients.Methods Retrospective clinical case control analysis.This study included 38 eyes of 20 acute VKH patients (VKH group) and 37 eyes of 37 acute CSC patients (CSC group).Seventy five eyes of 57 normal healthy subjects,matching patients with age and gender,were collected as control group.The disc RPE angle,the thickness of average CP-RNFL,the nasal,superior,temporal and inferior quadrant CP-RNFL thickness,and ONH parameters including optic disc area,cup area,rim area,C/D area ratio,linear CD ratio (CDR),vertical CDR were measured by 3D-OCT.Analysis of variance was performed for comparison among three groups.Minimum significant difference t test was performed for comparison between two groups.Results The differences of ONH parameters between VKH group and CSC group:29 eyes of VKH group appeared retinal detachment next to disc,only 12 eyes appeared in CSC group.Twenty one eyes of VKH group appeared optic disc hyperemia while none in CSC group.The three groups' disc RPE angles were (138.62± 11.96)°,(154.09±5.85)° and (153.41 ±5.77)°.VKH group were significantly smaller than CSC group (t=-2.05,P=0.00) and control group (t=-1.68,P=0.00),while there was no significant difference between CSC group and control group (t=-1.88,P=0.72).The optic cup area and rim area were significantly bigger in VKH group than in CSC group (t=4.61,2.71;P=0.00,0.01),and the thickness of mean CP-RNFL,all quadrants of CP-RNFL were significantly thicker in VKH group than in CSC group (t=6.25,4.40,3.53,5.48,2.69;P=0.00,0.00,0.00,0.00,0.01).Conclusion Compared with the acute CSC,VKH patients are likely to appear retinal detachment next to disc,their disc RPE angles are smaller,their optic cup area and rim area are bigger,and their CP-RNFL thickness are thicker.
ABSTRACT
Objective To test the reliability and validity of the Chinese version of Profile of Fatigue Scale (PROF)among the patients with Sjogren′s syndrome. Methods The English version of PROF was translated into Chinese according to Brislin Translation Model. 107 patients with Sjogren′s syndrome were investigated to test its reliability and validity. Results The Cronbachαcoefficient , Guttman split-half coefficient, test-retest reliability and content validity of Chinese version of PROF were 0.976, 0.953, 0.872 and 0.875. Two factors were extracted by factor analysis and the cumulated variance was 80.75%. The structure of PROF was in line with the original scale. The criterion-related validity was 0.621 measured by comparing with visual analog scale of fatigue, and was -0.707 measured by comparing with vitality domain in the MOS item Short From Health Survey (SF-36). Conclusions The Chinese version of PROF has been proved to be reliable and valid. It can be used to measure the fatigue in Chinese patients with Sjogren′s syndrome.
