Abstract
Traumatic sub-conjunctival dislocation of posterior chamber intraocular lens is a rare and emergency condition. This communication is to report a rare ocular trauma by cow horn. A 52 year old male farmer presented with history of cow horn injury to his right eye. He had pain redness and decreased vision in his right eye. His posterior chamber IOL which was implanted two years back,was found dislocated to superiotemporal sub-conjunctival space with one broken haptic in anterior chamber and was removed surgically. Such a dislocation has not yet been reported in Indan literature and rarely reported in international literature to the best of our knowledge.
Highlights
Intraocular lens implantation is a days routine practice in management of cataract patients
We report a case of posterior chamber IOL, implanted two years back with completely healed surgical wound, dislocated into subconjunctival space due to blunt trauma by cow horn
Though blunt ocular trauma caused by cow horn is a rare phenomenon but it can cause severe damage to the eye [8]
Summary
Intraocular lens implantation is a days routine practice in management of cataract patients. Previous studies have reported traumatic dislocation of intraocular lens into suprachoroidal space [1], vitreous cavity [2] and subconjunctival space [3,4,5]. Biedner et al reported subconjunctival dislocation of anterior chamber intraocular lens [6]. Kothari et al reported anterior dislocation of posterior chamber intraocular lens following blunt trauma by cricket ball [7].
