Ocular sequelae of pneumatic drills

Abstract

Purpose To determine the ocular sequelae of rockdrilling.

Methods Nineteen rockdrillers and 20 age-, sex- and race-matched control subjects underwent ocular examination in a prospective manner.

Results Subepithelial corneal opacities were found in 12 drillers (63%) and none of the controls; pigmented trabecular meshwork was noted in 13 drillers (68%) and 1 control (5%); low-tension glaucoma was diagnosed in 1 driller (5%); vitreous liquefaction was present in 17 of 17 drillers (100%) examined by a retina specialist and 9 of 20 controls (45%).

Conclusions The sequelae of drilling include corneal scars from proj ectile pieces of drilled stone as well as vibration-induced pigment deposition in the trabecular meshwork and vitreous liquefaction. Wearing of safety glasses is recommended.
