Endoscope-assisted pars plana vitrectomy useful in severe ocular trauma

Endoscope-assisted pars plana vitrectomy provided a clear view of the posterior segment in eyes with severe ocular trauma, according to a study.
The prospective case study comprised 50 consecutive trauma cases. Forty-three eyes had open-globe injuries; the intraocular foreign body was not retained in 32 eyes and was retained in 11 eyes. Seven eyes had post-traumatic endophthalmitis.
All eyes had ocular trauma that caused posterior segment pathology, but conventional viewing systems could not be used due to damage to the cornea or anterior segment.
In all eyes with open-globe injuries, 36 (83.7%) had improved vision after endoscope-assisted pars plana vitrectomy. Five endophthalmitis eyes (71.4%) had improved vision postoperatively.
“An endoscope allows earlier surgery in case of hazy media and better exploration of intraocular structures,” the study authors said. “It might reduce inflammatory processes and thereby suppress evolving anatomic changes before they lead to [proliferative vitreoretinopathy] and related complications.”
