| Introduction|| |
Cases of ocular trauma with intraocular foreign bodies (IOFBs) in the anterior chamber are relatively rare (15% of IOFBs). They are most commonly associated with nonmetallic projectiles with lower velocity. A majority of such incidences can be prevented with protective eyewear.
| Etiopathogenesis|| |
During any kind of penetrating trauma, the direction and site of impact, along with the mass and velocity of the foreign body (FB), determines its final position inside the eye. Objects with lower mass (usually nonmetallic) and lesser velocity seem to remain in the anterior chamber after penetration of the cornea. Such cases occur when there is splashing of the FB, commonly seen during drilling and without protective eyewear. In contrast, objects with a greater mass such as metallic FBs come to lie more commonly in the posterior segment.
| Case Report|| |
A 54-year-old male quarry worker presented with diminished vision and pain in the right eye (OD) after a piece of stone hit the eye, when he was drilling a few hours back. On examination, visual acuity in OD was counting fingers close to the face, improving to 6/9 with pinhole. Slit-lamp biomicroscopy of OD revealed diffuse conjunctival congestion, a self-sealed (Seidel's negative) corneal wound with localized corneal edema and a 4 mm × 5 mm (approximately) piece of stone lodged in the pupil, lying between the lens and the iris [Figure 1]. The lens capsule and iris appeared to be normal without any damage. Posterior segment was within normal limits. The patient was advised for OD primary corneal repair with FB extraction, but unfortunately, he failed to follow-up for the surgery.

Such FBs should be managed as early as possible due to the potential of giving rise to serious complications such as endophthalmitis, hyphema, cataract, and retinal detachment., Prompt management is of importance, but wearing protective eyewear is the first step in avoiding such injuries.
