Intraocular endoscopy in the management of ocular trauma: clinical settings and treatment outcomes at a tertiary eye care centre.

PURPOSE

To report the application of endoscopy in the management of ocular trauma, describe the clinical settings and the treatment outcomes.

METHODS

Retrospective, consecutive, non-comparative case series at a tertiary eye care centre. Data recorded included aetiology of trauma, presenting vision, corneal condition at presentation, per-operative clinical findings during endoscopy, prognostication of the cases on table, final visual and anatomic outcome. Odds ratios for a favourable outcome were computed for various surgical indications.

RESULTS

The study included 58 eyes of 58 patients. Males constituted 82% of all cases. Mean age at presentation was 35.55 ± 18.9 years, median 31.5 years. Commonest corneal condition causing opaque media was corneal oedema (44.8%) followed by corneal laceration in 25.8%, repaired corneal laceration in 13.7% and scarred cornea in 12%. Commonest indication for surgery was retinal detachment (36.2%) followed by vitreous haemorrhage (29.3%), retained foreign body (13.7%) and combined detachment with haemorrhage in 10.3%. Of the 58 eyes, 17 eyes were deemed inoperable on endoscopic examination and 11 eyes were deemed to have poor prognosis. Of the fair prognosis (n = 30), 60% had final vision of 20/400 (p = 0.0001) compared to 10% before surgery and 13.33% had final vision of 20/40 (p = 0.03) as compared to nil in the pre-operative period. Odds ratio for a favourable visual outcome was best for the indication of vitreous haemorrhage (OR = 9, p = 0.0006).

CONCLUSION

Endoscopy in ocular trauma with opaque media provides adequate visualisation and allows for prognostication. In cases deemed to have prognosis, suitable intervention leads to globe and vision salvage.
