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 P < .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.
