Динамика толщины сосудистой оболочки при передних увеитах без видимых ретинальных изменений

Abstract

Purpose. To assess the state of the choroid in patients with HLA-B27-associated anterior uveitis without detectable lesions of the macular zone by ophthalmoscopy. Material and methods. 22 patients with HLA-B27-associated acute anterior uveitis without detectable changes in the macular zone by ophthalmoscopy – the main group. Age: 39.02±13.76 years, men – 16 and women – 8. Best corrected visual acuity varied from 0.1 to 0.5 (average 0.3). The level of intraocular pressure according to Maklakov in all eyes varied from 15 to 22 mm Hg. The parameters of paired intact eyes of patients served as a control. The subfoveal choroid thickness (CT) was determined using optical coherence tomography in comparison with paired intact eyes before treatment and 2 weeks after its initiation. Results. The initial values of the CT indexes in the main group varied from 337 to 371 μm, averaging 354±8 μm. This is statistically significantly higher than in intact paired eyes 255±7 μm (from 246 to 268 μm), p <0.001. 2 weeks after the start of treatment CT indexes in the main group were 268±10 μm, which was statistically significantly lower than the initial indexes in this group, p<0.001. In paired eyes, they were 254±6 μm. Conclusion. A statistically significant increase in CT was revealed in the eyes of patients with acute anterior uveitis, which statistically significantly exceeded the values of the paired intact eye on average on 100 μm. 2 weeks after the start of treatment, the CT indexes statistically significantly decreased to 268±10 μm, which did not differ statistically significantly from the CT indexes of the intact eye. Key words: anterior uveitis, HLA-B27, choroidal thickness.
