ObjectiveTo measure and analyze the oxygen saturation and retinal blood vessel diameter in the eyes of patients with convalescence Vogt-Koyanagi-Harada (VKH) syndrome. MethodsIn this cross-sectional study, 28 eyes of 14 patients with convalescence VKH syndrome (VKH group) and 20 eyes of 10 healthy subjects (control group) were enrolled. The oxygen saturation and retinal blood vessel diameter were detected by spectrophotometric oximetry unit. Retinal images were collected using filters with wavelengths of 570 nm and 600 nm in the darkroom by the same technologist and then the fused image was obtained. The oxygen saturation of retinal vessels was marked in different colors. The measurement was repeated 2-3 times for each patient, then take an average. A top-quality image in each eye was selected to detect the oxygen saturation and diameter of retinal vessel which located in 1.5-3.0 disc diameter from the optic disc. Image analysis and data acquisition were completed by another technologist. ResultsRetinal venous oxygen saturation was (54.34±8.05)% in the VKH group and (60.07±7.91)% in the control group. The former was lower than the latter, the difference was significant (t=2.443, P=0.017). The mean diameter of retinal arteries was (102.8±18.1) μm in the VKH group and (112.9±19.8) μm in the control group. The former was smaller than the latter, the difference was significant (t=2.406, P=0.018). There was no significant difference of the mean diameter of retinal veins, oxygen saturation of retinal arteries and the arterial-venous difference between two groups (t=-0.330, 0.804, -0.631; P=0.743, 0.403, 0.536). ConclusionsRetinal venous oxygen saturation and the mean diameter of retinal arteries are significantly decreased in patients with VKH syndrome. There is no significant difference of diameter of retinal veins, oxygen saturation of retinal arteries and the arterial-venous difference between VKH syndrome patients and healthy subjects.
Objective To investigate the cilinical value of indocyanine green angiography(ICGA) in patients with Vogt-Koyanagi-Harada syndrome(VKH). Methods Fundus fluorescein angiography(FFA) and indocyanine green angiography(ICGA) were used for comparative analyses in 26 cases(52 eyes)of VKH. Results In the acute stage of VKH,FFA revealed the multifocal leakage in the pigment epithelium and the multifocal serous retinal detachment,and the typical FFA manifestations disappeard following treatment．In the acute stage of the disease the ICGA showed:(1)numerous patchy areas of hypofluorescence and decreased flurescence in large and middle choroidal vessels(66.7%);(2)dilatation of the choroidal vessels(70.8%)and(3)in latephase of ICGA,the patchy areas of hyperfluorescence(79.2%).During the recovery stage of the disease,the abnormal undings in ICGA were resolved slower than those found in FFA. Conclusions ICGA may assist in providing valuable informations on choroidal circulation of VKH and be useful in evaluating the curative effects． (Chin J Ocul Fundus Dis,20000,16:9-11)
Objective To study choroidal vascular abnormal characterisitics in Harada is disease using indocyanine green angiography (ICGA)． Methods Twenty-six cases(52 eyes)of Harada is disease were examined with fundus fluorescein angiography(FFA) and ICGA． Results ICGA findings in Harada is disease were as follows:(1)choroidal hypofluorescence with edema in the early phase;(2)choroidal filling defects;(3)dilatation of choroidal vessels and vortex veins;(4)choroidal hyperpermeability in late period;(5)multifocal lower fluorescence in the midperiphery and posterior pole of the fundus in the late phase. Conclusions ICGA can find lesions of the choroidal vessels i．e． hypofluorescence with edema,disturbances of choroidal circulation，dilatation of choroidal vessels and vortex veins and the lower fluorescence maculation in the early phase and choroidal hyperpermeability in the late phase． (Chin J Ocul Fundus Dis,20000,16:12-13)
ObjectiveTo compare the clinical features of patients with acute Vogt-Koyanagi-Harada syndrome (VKH syndrome) of optic disc swelling (ODS) and serous retinal detachment (RD).MethodsA retrospective clinical study. From January 2013 to November 2019, 212 patients with acute VKH syndrome diagnosed in the Department of Ophthalmology of Shanghai Xuhui District Central Hospital were included in the study. Among them, there were 105 males (210 eyes) and 107 females (214 eyes). The average age was 40.84±13.90 years. All affected eyes were examined by BCVA, FFA, and OCT. The standard logarithmic visual acuity chart was used for BCVA examination, which was converted into logMAR visual acuity in statistics. According to the changes in the fundus, the patients were divided into the ODS group and the RD group, 36 patients with 72 eyes (16.98%) and 176 patients with 352 eyes (83.02%), respectively. The independent sample t test was performed to compare the age of onset, visit time and BCVA of the two groups of patients, the χ2 test was performed to compare the count data.ResultsAmong the 72 eyes of 36 patients in the ODS group, there were 16 males with 32 eyes (44.44%), 20 females with 40 eyes (55.56%). The average age was 40.56±16.57 years, the average visit time was 22.47±19.98 days, the average logMAR BCVA was 0.68±0.53. Among the 352 eyes of 176 patients in the RD group, there were 89 male patients with 178 eyes (50.56%), and 87 female patients with 174 eyes (49.43%). The average age was 40.90±13.34 years, the average visit time was 17.25±24.40 days, the average logMAR BCVA was 0.80±0.56. The average age (t=－0.116), gender composition ratio (χ2=0.448), average visit time (t=1.204), average logMAR BCVA (t=－1.661) comparisons between the two groups showed no statistically significant differences (P＞0.05). There was no statistically significant difference in the average logMAR BCVA between the RD group and the ODS group of different eyes (t=0.227, 0.810; P＞0.05). There were 50 (69.44%, 50/72) and 272 (77.27%, 272/352) eyes in the ODS group and RD group with inflammation of the anterior segment. There were anterior segment reactions between the two groups. There was no statistically significant difference in the number of eyes (χ2=1.003, P＞0.05). There were 34 (19.32%, 34/176) and 2 (5.56%, 2/36) patients with headache and hearing loss, respectively. The comparison of the number of patients with headache and hearing loss between the two groups showed statistically significant differences (χ2=4.015, P＜0.05).ConclusionCompared the patients with ODS acute VKH syndrome, the patients with serous RD acute VKH syndrome are more likely to have extraocular symptoms such as headache and hearing loss.
ObjectiveTo analyze the risk factors for seizures in patients with autoimmune encephalitis (AE) and to assess their predictive value for seizures. MethodsSeventy-four patients with AE from the First Affiliated Hospital of Xinjiang Medical University from January 2016 to March 2023 were collected and divided into seizure group (56 cases) and non-seizure group (18 cases), comparing the general clinical information, laboratory tests and imaging examinations and other related data of the two groups. The risk factors for seizures in AE patients were analyzed by multifactorial logistic regression, and their predictive value was assessed by receiver operating characteristic (ROC) curves. ResultsThe seizure group had a higher proportion of acute onset conditions in the underlying demographics compared with the non-seizure group (P<0.05). Laboratory data showed statistically significant differences in neutrophil count, calcitoninogen, lactate dehydrogenase, C-reactive protein, homocysteine, and interleukin-6 compared between the two groups (all P<0.05). Multi-factor logistic regression analysis of the above differential indicators showed that increased C-reactive protein [Odds ratio (OR)=4.621, 95% CI (1.123, 19.011), P=0.034], high homocysteine [OR=12.309, 95CI (2.217, 68.340), P=0.004] and onset of disease [OR=4.918, 95% CI (1.254, 19.228), P=0.022] were risk factors for seizures in AE patients, and the area under the ROC curve for the combination of the three indicators to predict seizures in AE patients was 0.856 [95% CI (0.746, 0.966)], with a sensitivity of 73.2% and a specificity of 83.3%. ConclusionHigh C-reactive protein, high homocysteine and acute onset are independent risk factors for seizures in patients with AE, and the combination of the three indices can better predict seizure status in patients.
