목적 : To evaluate retinal nerve fiber layer (RNFL) thickness in eyes with unilateral Posner-Schlossman syndrome (PSS) without visual field defects by using spectral-domain optical coherence tomography (SD-OCT).
방법 : Forty-two subjects with unilateral PSS without visual field defects in standard automated perimetry were enrolled. Nine out of 42 subjects had only a single episode of previous intraocular pressure (IOP) increase (group A), and other 33 patients had two or more episodes of previous IOP increase (group B). RNFL thicknesses in global area, 4 quadrants, and 12 clock-hour sectors obtained by SD-OCT were compared between eyes with PSS and their fellow eyes without PSS.
결과 : In the group A, no significant difference was found in RNFL thickness between eyes with PSS and their fellow eyes without PSS (P > 0.05). In contrast, in the group B, RNFL in eyes with PSS was thinner than RNFL of their fellow eyes in global area, superior and inferior quadrants, and 7 and 12 o’clock sectors (P < 0.05).
결론 : Although visual field defects were not present, eyes with PSS had thinner RNFL than eyes without PSS, especially when multiple episodes of previous IOP increase were present. These findings should be considered when evaluating eyes with PSS.
