Purpose: To describe clinical findings and analyze treatment evolution of chronic, non-infectious uveitis in patients with juvenile idiopathic arthritis (JIA).
Methods: A total of 82 patients (147 eyes) with JIA-related uveitis treated for ≥2 months were included (78% females; 79% bilateral uveitis; 74% anterior uveitis). Outcome measures were visual acuity (VA), inflammation control, side-effects, and surgical procedures.
Results: Mean ± SD age at diagnosis was 4.9 ± 3.8 years; mean ± SD follow-up time was 8.7 ± 7.8 years. Mean VA did not significantly change throughout the study. Three (2%) eyes resulted in no light perception (NLP) vision. Thirty (37%) patients underwent 69 procedures. In total, 41 (50%) patients achieved inflammation control. TNF-α inhibitors were significantly associated with inflammation control. Seven (8.5%) patients stopped treatment due to side-effects.
Conclusions: JIA is a cause of significant ocular morbidity. TNF-α inhibitor use was associated with inflammation control. Prospective, randomized, double blind clinical trials in this regard are warranted. 相似文献
AIM: To compare the safety and efficacy of conventional versus accelerated (9 mW/cm2) CXL in progressive keratoconus at the 2-year follow-up. METHODS: In this prospective study, consecutive progressive keratoconus patients were randomized to receive either conventional CXL (CCXL) or accelerated CXL (ACXL, using hydroxypropyl methylcellulose-assisted riboflavin imbibition for 10min) at 9 mW/cm2. Visual, refractive, keratometric, topographic, and aberrometric outcomes and stromal demarcation line depth (DLD) measurements were compared at the end of a 2-year follow-up. RESULTS: Thirty-two eyes from 32 patients in the CCXL and 27 eyes from 27 patients in the ACXL groups completed 2-year follow-ups. At 2 years post-CXL, both uncorrected and corrected visual acuities improved significantly in both groups. The improvements in keratometric readings, flattening rate (flattening of the Kmax more than 1D), 3 topographic indices, and vertical coma were significantly better in the CCXL group compared to the ACXL group (P<0.05). The DLD as measured by anterior segment optical coherence tomography or in vivo confocal microscopy was better detectable and significantly deeper in the CCXL group compared to the ACXL group. The deeper DLD was found to be significantly correlated with improvements in the mean keratometry measurements. Progression was noted in 11.1% of eyes in the ACXL group, whereas progression was not observed in any patient eye in the CCXL group. CONCLUSION: In this prospective randomized study, ACXL was less effective in halting the progression of keratoconus at a 2-year follow-up compared to CCXL. 相似文献
Seven xanthone glycosides were isolated from the cortexes of Polygala tenuifolia, and their structures were identified as polygalaxanthones VIII-XI (1-4), sibiricoxanthone B (5), 7-O-methylmangiferin (6), and lancerin (7), on the basis of spectroscopic analyses. Compounds 1-4 are new xanthone glycosides, and compounds 4 and 5 exist as rotamers. To explain this phenomenon, conformational analyses were performed on compounds 4 and 5 and other compounds with similar skeletons that were isolated from P. tenuifolia. 相似文献
