■为了研究先天性静止性夜盲症(CSNB)的微视野和光学相干断层扫描(OCT)的特征,以及它们的结构-功能关联。
■这项横断面研究包括来自32名CSNB参与者的32只眼睛,包括18个完整的CSNB和14个不完整的CSNB,以及36只CSNB未受影响的对照组的36只眼睛与年龄相匹配,性别,和球形等效。使用MP-3显微视野,在20°视野内评估中央视网膜敏感度,分布在六个同心环(0°,2°,4°,6°,8°,和10°)。使用OCT分析视网膜和脉络膜厚度。该研究旨在评估整体和环状视网膜敏感性,以及CSNB和CSNB未受影响的对照组的脉络膜和视网膜厚度,其次关注视网膜敏感性与OCT微结构特征之间的关系。
■与未受CSNB影响的受试者相比,CSNB患者的总体和环状视网膜敏感性以及脉络膜厚度均降低(P<0.001).此外,不完全CSNB组的中枢敏感性低于完全CSNB组(25.72±3.93dBvs.21.92±4.10dB;P<0.001)。与未受CSNB影响的组相比,CSNB组的视网膜厚度在中央凹外侧更薄。多重混合回归分析显示,点对点视网膜敏感性与BCVA(P=0.002)和相应的视网膜厚度(P=0.004)显着相关。
■视网膜敏感性和OCT检查显示CSNB及其亚型的空间分布特征不同。在CSNB眼中,微视野的视网膜敏感性与OCT的视网膜厚度相关.
UNASSIGNED: To investigate the characteristics of microperimetry and optical coherence tomography (OCT) in congenital stationary night blindness (CSNB), as well as their structure-function association.
UNASSIGNED: This cross-sectional study included 32 eyes from 32 participants with CSNB, comprising 18 with complete CSNB and 14 with incomplete CSNB, along with 36 eyes from 36 CSNB-unaffected controls matched for age, sex, and spherical equivalent. Using MP-3 microperimetry, central retinal sensitivity was assessed within a 20° field, distributed across six concentric rings (0°, 2°, 4°, 6°, 8°, and 10°). OCT was used to analyze retinal and choroidal thickness. The study aimed to assess the overall and ring-wise retinal sensitivity, as well as choroidal and retinal thickness in CSNB and CSNB-unaffected controls, with a secondary focus on the relationship between retinal sensitivity and microstructural features on OCT.
UNASSIGNED: In comparison with CSNB-unaffected subjects, the overall and ring-wise retinal sensitivity as well as choroidal thickness were reduced in patients with CSNB (P < 0.001). Moreover, the central sensitivity in incomplete CSNB group was lower than in complete CSNB group (25.72 ± 3.93 dB vs. 21.92 ± 4.10 dB; P < 0.001). The retinal thickness in the CSNB group was thinner outside the fovea compared with the CSNB-unaffected group. Multiple mixed regression analyses revealed that point-to-point retinal sensitivity was significantly correlated with BCVA (P = 0.002) and the corresponding retinal thickness (P = 0.004).
UNASSIGNED: Examination of retinal sensitivity and OCT revealed different spatial distribution profiles in CSNB and its subtypes. In CSNB eyes, retinal sensitivity on microperimetry was associated with retinal thickness on OCT.
