At the diagnostic point, results of the Hess screen test revealed -2 grade of gaze limitation at lateral gaze of the left eye paralysis eye (A). Vessel densities of radial peripapillary capillary (RPC), superficial capillary plexus (SCP), and deep capillary plexus (DCP) were compared between the paralysis eye (B) and contralateral nonparalysis eye (C).
