Evaluation of vitrectomy in penetrating ocular trauma. A case-control study
E. de Juan Jr, P. Sternberg Jr, R. G. Michels and C. Auer
A case-control retrospective evaluation of vitrectomy in penetrating ocular
trauma was performed by matching 89 eyes, managed with vitrectomy, with 89
similar eyes that did not undergo vitrectomy. The cases were matched
according to factors previously shown to correlate with the visual outcome,
including the following: (1) type of trauma; (2) length and posterior
extent of the laceration; (3) type and degree of lens involvement; and (4)
type and location of any intraocular foreign body. The groups differed in
the distribution of initial visual acuity, which was worse in the
vitrectomy group. When the final visual results were compared, no
statistical advantage from vitrectomy was found. However, beneficial trends
were demonstrated in air rifle and double-penetrating injuries, as well as
in other severe injuries in which initial visual acuity was worse than
5/200.
