Treatment of NLP Induced by Explosion on August 12, in Tianjin Harbor



Two eyes of two patients suffered from explosion occurred on August 12, 2015 in Tianjin Harbor. The two injured eyes had vision of no light perception. The ocular wound was sutured tightly and IOP was normal by the injection of Healon into the vitreous cavity in the emergency surgery. The scleral rupture, hyphema, vitreous hemorrhage, retinal and choroidal detachment, superochoroidal hemorrhage were observed by slit lamp examination, B-scan, and CT in two eyes. The combined standardized three-port vitrectomy were performed at 13 days after the primary emergency surgery. The vi trectomy had been done by the use of wide-angle viewing system and chandelier light under systemic anesthesia. Traumatic cataract was removed by phacoemulsification firstly, and then the vitreous hemorrhage was removed. Epiretinal and subretinal membrane were completely peeled by the use of TA staining. Retinectomy was performed at the retinal stiffen area, and retinotomy was used for removal of subretinal proliferation. Perflurocarbon liquids were used to make the retina attached very well, followed by the laser photocoagulation treatment. Finally, the silicone oil tamponade was injected into the vitreous cavity after air-fluid exchange. The postoperative complications mainly included exudates in the anterior chamber, temporary IOP elevation, and hyphema. The final visual acuity were 0.1 and 0.3 in two patients respectively, and retina attachment were achieved. IOP were in normal range. The standardized three port combined vitrectomy with the use of wide-angle viewing system and ch andelier light is a safe and effective approach in treating severe open-globe injury with the vision of no light perception. The long-term outcomes of this combined treatment should be observed and explored.
