Purpose:
This case report aims to describe a rare case of asymptomatic retained metallic intraocular foreign body (IOFB) in the retina with reduced full-field electroretinography (ff-ERG) in a Chinese woman.
Methods:
This is a clinical investigation of a patient who unexpectedly presented with a metallic IOFB at the superior-temporal region of the left eye ring during a brain computed tomography.
Results:
Her best-corrected visual acuity was 20/20 in both eyes. The dilated fundus photograph of the left eye revealed a metallic IOFB in the retina. She reported no ocular symptoms. A diagnosis of asymptomatic metallic IOFB was made definitely. The subsequent ff-ERG demonstrated subnormal amplitudes of dark and light adaption in the left eye, whereas responses were normal in the right eye.
Conclusions:
Our findings suggest the application of ff-ERG has important benefits for evaluating the visual function in patients with retained IOFB.

Schottky Barriers
Schottky barriers arise when a metal with a work function (Φm) contacts a semiconductor with a different work function (Φs). Initially, electrons transfer until the Fermi levels of the metal and semiconductor align at equilibrium. For instance, if Φm > Φs, the semiconductor Fermi level is higher than the metal's before contact. The semiconductor's...
