Endoscope-assisted pars plana vitrectomy in severe ocular trauma.

Purpose: To report the results of pars plana vitrectomy (PPV) assisted by ophthalmic endoscope (OE) in severe ocular trauma cases which are unsuitable for PPV using wide-angle contact/non-contact lens due to media haze and/or disorganised anterior segment.

Methods: Prospective, non-comparative, interventional case series. Main outcome measured was anatomic status of the retina postoperatively, secondary outcome measured was functional status regarding vision, intraocular pressure and control of inflammation in cases of endophthalmitis.

Results: Fifty trauma cases were included in the study. Out of these, 43 eyes had open globe injuries (32 eyes without intraocular foreign body (IOFB), and 11 eyes with retained IOFB), and seven eyes had post-traumatic endophthalmitis. In the open globe injury group, 36 (83.7%) eyes reported improvement in vision. In endophthalmitis group, five eyes showed improvement in vision.

Conclusions: OE provided a clear view to conduct PPV in select trauma cases where delay in surgery due to hazy media or due to non-availability of donor cornea for simultaneous penetrating keratoplasty can lead to severe proliferative vitreoretinopathy changes.
