Purpose:
The aim of this study was to determine visual and anatomical outcome of perforating injuries due to shotgun pellet.
Methods:
This was a prospective observational study carried out between July 2016 and Jan 2019 at a tertiary care referral center in Srinagar, Jammu and Kashmir. A total of 172 eyes with perforating injuries of 170 patients were included in the study and were followed up for 6 months with best-corrected visual acuity, slit-lamp examination for status of anterior chamber and lens, fundus examination for status of retina and media, intraocular pressure measurements, and OCT (optical coherence tomography) and FFA (fundus fluoresceine angiography) in selected cases. The relative improvement of visual acuity after treatment was interpreted by applying paired two-tailed t tests. Prognostic significance of other variables was calculated using Chi-square and Chi-square for linear trend tests, for two dependent outcome variables of good outcome and poor outcome.
Results:
WHO category 4 visual impairment was found in 66 (38.4%) eyes, whereas category 0 was found in 24 (14%) of eyes. Retina was found to be attached 99 (57.6%) of study eyes.
Conclusion:
Perforating injury is a severe form of ocular trauma with grave consequences in terms of functional and anatomical outcome.
