Résumé
Objective:To compare the clinical features of patients with acute Vogt-Koyanagi-Harada syndrome (VKH syndrome) of optic disc swelling (ODS) and serous retinal detachment (RD).Methods:A 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. Results:Among 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). Conclusion:Compared 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.

Objective To investigate the effect of advanced glycation end products(AGEs)on expression of vascular endothelial growth factor(VEGF)in rabbit retinal M?ller cells in vitro.Methods We successfully cultured rabbit retinal M?ller cells and made AGEs-BSA as well as its control in vitro.Study with M?ller cells were divided into AGEs-BSA group,AGEs-BSA control group and blank control group.AGEs-BSA group and AGEs-BSA control group were respectively treated with 5 different concentration series of AGEs-BSA and AGEs-BSA control and cultured for 3,6 and 9 days,while blank control group was incubated without any intervention.Then VEGF expression in M?ller cells was observed by immunocytochemistry(ICC).Results Compared with control group,VEGF expression in cultured retinal M?ller cells was significantly enhanced in AGEs-BSA group.And the effects were in the time-and concentration-dependent manners.Conclusions AGEs increases VEGF expression in rabbit retinal M?ller cells in vitro,which indicates that AGEs may promote the progression of diabetic retinopathy(DR)through the induction of VEGF expression.
