Optical Coherence Tomography Angiography in Posner-Schlossman Syndrome - A Preliminary Study.

Purpose: To evaluate vessel density (VD) and structural features in Posner-Schlossman syndrome (PSS) patients' eyes using optical coherence tomography angiography (OCTA).

Methods: An observational study was conducted among 23 affected eyes (group A), 23 contralateral unaffected eyes (group B), and 23 control eyes (group C).

Result: The macular superficial, macular deep, and optic nerve head (ONH) VD of group A were 45.26 ± 5.80, 46.78 ± 6.96, and 46.10 ± 4.22, respectively. The macular superficial VD, macular deep VD, and retinal thickness of group A were significantly lower than those of group C (all < .05). The retinal nerve fiber layer thickness of group A decreased in the superior and inferior sections. The macular superficial VD had the highest diagnostic value (area under curve = 0.989) for PSS.

Conclusion: OCTA can detect the fundus change in the macular and ONH regions of the PSS's affected eyes.
