Surgical treatment for severe ocular rupture with blood staining of cornea and non-light perception / 中华眼底病杂志

ABSTRACT

Objective To evaluate the effects of surgical treatment for severe ocular rupture with blood staining of cornea and non-light perception, and analyze the relative factors. Methods Seven severely ruptured eyes of 7 patients with blood staining of cornea and non-light perception underwent second-stage penetrating keratoplasty combined with vitrectomy using temporary keratoprosthesis. All injured eyes had blood staining of cornea, hemorrhage in anterior chamber and vitreous, and choroidal and retinal detachment before the second-stage surgery. The average interval of the two surgical stages was 18 days (12-21 days). The preoperative visual acuity was non-light perception in all injured eyes with the mean intraocular pressure of 3 mm Hg (1 mm Hg=0.133 kPa) (2- 5 mm Hg). The mean follow-up period was 12 months (6-30 months). Results The postoperative visual acuity was better than light perception in 5 eyes with the best corrected visual acuity of light perception to 0.06. The retina was attached in 5 eyes (5/7). The mean postoperative intraocular pressure was 12 mm Hg (5- 15 mm Hg) which was significantly higher than the preoperative one (P
