At the time of his first visit, his best-corrected visual acuity was hand motion in the right eye. A 23 G three port pars plana vitrectomy was conducted in combination with ophthalmic endoscope and a wide-angle viewing system. Endoscopy revealed a retinal detachment in the inferior quadrant with tiny retinal breaks. Primary reattachment of the retina was achieved by tamponade of SF6 gas. Five months after the vitrectomy, penetrating keratoplasty was performed and visual acuity recovered to 0.02. Optical coherent tomography revealed thinning of the retina, which might be the cause of the remaining poor vision.Conclusion: 23 G vitrectomy assisted by combined endoscopy and a wide-angle viewing system could be advantageous in managing visualization constraints due to penetrating trauma.Keywords: penetrating injury, vitrectomy, endoscope, wide angle viewing system, 23 gauge vitrectomy
