[Evaluation of endoscopy assisted vitrectomy for the treatment of severe traumatic eyes with no light perception].

Objective: To evaluate the effect of endoscopy assisted pars plana vitrectomy for severe ocular trauma with no light perception.

Methods: A retrospective case-series study. Medical records of 6 eyes of 6 patients undergoing endoscopy assisted vitrectomy for severe ocular trauma with no light perception from December 2006 to August 2009 were studied. Four patients were male and 2 patients were female. Their age ranged from 6 to 67 years old with an mean age of 38 years. History of trauma, visual acuity prior to vitrectomy and at final follow-up, bacterial culture results and surgical approaches were recorded.

Results: Visual acuity prior to vitrectomy was no light perception in all the 6 patients with a mean intraocular pressure of 3 mmHg (1 mmHg=0.133 kPa) . All the patients had diffuse corneal edema along with opacities caused by corneal perforation from trauma in 3 patients, blood staining of cornea in 2 patients and endophthalmitis in 1 patient. B-scan ultrasound echography carried out before surgery showing that all the patients had retinal detachment. Three patients' vitreous samples were sent for bacterial culture. Bacillus cereus, S.epidermidis and Aeromonas Hydrophila were identified respectively. Patients were followed up for 18 to 36 months. Postoperatively, 5 of the patients' visual acuity was better than light perception, ranging from light perception to 0.04. The retina was reattached in 4 patients.

Conclusion: Endoscopy assisted vitrectomy is a safe and effective option for the treatment of severe traumatic eye with no light perception.
