Delayed presentation of severe ocular injury from a button battery.

A 2-year-old girl presented to the emergency department at 3:00 h with severe pain in her right eye and a rust coloured, blood stained frothy discharge that had woken her. An examination of her eye revealed a shiny metallic looking foreign body, which was immediately removed by the on-call ophthalmologist. That morning the patient underwent ocular examination under anaesthesia and was found to have severe tissue necrosis resulting from an electrochemical burn. She was treated with daily rodding for 3 days and betamethasone ointment four times a day, which was gradually tapered. At 3 months her only eye pathology was a mild symblepharon between the bulbar and tarsal conjunctiva. This is the first case of delayed symptoms after placement of a button battery into the conjunctival fornix. This case highlights the serious nature of button battery injuries to the eye and the potential to miss the diagnosis owing to a delayed onset of symptoms.

Long-term visual and retinopathy outcomes in a predominately type 2 diabetic patient population undergoing early vitrectomy and endolaser for severe vitreous haemorrhage.

PURPOSE: To evaluate the long-term visual outcome of type 2 diabetic patients receiving early vitrectomy and endolaser for severe vitreous haemorrhage (VH). MATERIALS AND METHODS: Retrospective case note review of 88 eyes (69 type 2 diabetics and 19 type 1 diabetics) of 80 patients who underwent vitrectomy and endolaser within 6 months of VH. Post-operative and most recent VA, in addition to long-term retinopathy grading, were analysed. A subset of patients fulfilling the criteria for the Diabetic Retinopathy Vitrectomy Study was compared with this study. RESULTS: Mean pre-operative visual acuity (VA) in the type 2 group was 0.64 logMAR, with 1 eye showing perception light (PL), 10 eyes detecting hand movements (HMs), and 7 eyes counting fingers (CFs). At the 2-week post-operative visit, the mean VA had improved to 0.46 logMAR, with two eyes showing PL, two eyes detecting HM, and one eye CF (P=0.0002); at the last review, mean VA score was 0.36 logMAR, with three eyes showing PL and four eyes detecting HM (P=0.0008). Mean pre-operative VA in the type 1 group was 0.47 logMAR, with one eye showing PL, one eye detecting HM, and two eyes CF. At the 2-week post-operative visit, the mean VA had improved to 0.37 logMAR, with one eye showing PL (P=0.002), and at the latest review, the mean VA was 0.20 logMAR (P=0.027). CONCLUSION: Our study shows that type 2 DM patients can observe improvement in VA and stabilisation of their proliferative retinopathy after early vitrectomy and endolaser for vitreous haemorrahage, which is maintained after long-term follow-up.
