Abstract

Purpose:

To report polyethylene as an unusual cause of corneal foreign body.

Methods:

Two patients presenting with ocular complaints showed a transparent foreign body on the cornea on careful slit-lamp examination. The foreign bodies were removed and subjected to chemical analysis by Fourier transform infrared spectrophotometry. Treatment was given in the form of topical antibiotics and tear substitutes.

Results:

The foreign bodies were identified as polyethylene. There were no sequelae after foreign-body removal.

Conclusions:

Because of its transparent nature, polyethylene can be easily missed as a corneal foreign body. A meticulous slit-lamp examination is mandatory to identify it early for appropriate management.
