Trauma-induced filtering bleb formation and blebitis 40 years following a penetrating eye injury

A 49-year-old man presented to the emergency eye clinic with a 3-week history of redness, irritation and blurred vision in his right eye, with a noticeable lesion superotemporally on the conjunctiva. He had a previous ocular history of penetrating glass injury in the right eye at the age of 9 years (40 years ago), of which no surgical intervention was performed at that time, as his parents did not seek medical attention. Slit lamp examination revealed a thin, conjunctival cystic bleb at 10 o'clock position with surrounding conjunctival injection and chemosis at close proximity to the site of previous ocular trauma. Investigations confirmed a diagnosis of trauma-induced filtering bleb with blebitis (bleb inflammation). The patient was treated with a combination of steroid and antibiotic drops for duration of 2 weeks. Subsequent follow-up revealed marked improvement of symptoms with reduced inflammation. Patient is being monitored regularly to prevent recurrence of blebitis and bleb associated complications.
