Abstract

Introduction: With the advance of ultra-widefield fundus imaging, its usefulness for fluorescein angiography study compared to the conventional (50°) for uveitis management is not fully studied. We aimed to compare ultra-widefield fluorescein angiography (UWFFA) and simulated conventional (50°) FA in terms of peripheral fundus findings and its correlation with clinical activity and therapeutic decision changes in uveitis cases. Methods: We performed a descriptive retrospective study in uveitis patients who underwent UWFFA (Optos P200DTx California) in March-May 2021. We compared the presence of peripheral abnormalities between UWFFA images and its simulated 50° FA. We correlated them with clinical uveitis activities and therapeutic decision changes by two uveitis experts. Results: We included 12 uveitis patients and found that 44.4% of peripheral vascular leakage, 83.3% of the peripheral lesion, and 100% of peripheral neovascularization in UWFFA were missed in simulated 50° FA. From 5 clinically inactive patients, 4 out of 5 were assessed as active uveitis on simulated 50° FA interpretation, and all the inactive patients were active uveitis based on UWFFA. 1 out of 12 had a diagnosis and therapeutic changes after UWFFA. Conclusions: We found more peripheral findings in UWFFA than in conventional ones. This discrepancy could alter clinical activity and therapy decisions, and long-term studies are needed to assess the clinical benefit.

Abstract

Introduction: HLA-B27 is a genetic marker strongly associated with spondyloarthropathy (SpA) and acute anterior uveitis (AAU). Detection of this allele can support earlier diagnosis and targeted management. However, commercially available HLA-B27 tests are costly and often inaccessible in low- and middle-income countries, including Indonesia. Methods: A cross-sectional study was conducted involving 42 subjects: 14 with SpA, 19 with AAU, and 9 healthy controls. DNA was extracted from peripheral blood samples and analyzed using both conventional PCR (targeting exon 3 of HLA-B27) and a commercial HLA-B27 strip assay. Sensitivity, specificity, and diagnostic accuracy of conventional PCR were calculated against the commercial kit as the reference standard. Results: Conventional PCR showed high sensitivity (100%) and accuracy (85.71%) in SpA patients, indicating its potential as a reliable screening tool in this group. However, its performance in AAU patients was suboptimal, with lower sensitivity (40%) and specificity (55.56%). False positives and false negatives were observed, likely due to limitations in allele coverage by conventional primers. Conclusion: Conventional PCR is a promising, affordable alternative for HLA-B27 detection in SpA patients, particularly in resource-limited settings. However, its lower reliability in AAU cases highlights the need for careful clinical application and further optimization. Larger studies and local allele mapping are recommended to enhance diagnostic precision in diverse populations.
