The Result of Consecutive Vitrectomy in Penetrating Ocular Injury

We studied retrospectively the results of consecutive vitrectomy following traumatic ruptured globe repair in 31 patients, who had been followed six months or longer postoperatively. Twenty-seven patients (87%) were male and 21 (68%) were between the second and fourth decades. Functional success was achieved in 13 patients(42%) and anatomic success in 14 patients(45%). Nine patients vitrectomized within two weeks after primary repair had 100% success rate, and seven patients operated between two weeks and one month had 96% success rate, but 15 patients vitrectomized after one month had 80% success rate. Five among eight eyes which underwent other operations prior to vitrectomy showed success, in contrast to 96% (22 eyes) success among 23 eyes which underwent planned vitrectomy without any other intervening surgical procedure. Better previtrectomy conditions including simple vitreoretinal incarceration or proliferative vitreoretinopathy of Grade B or milder achieved success in 96%, but poor conditions including prephthisical status and proliferative vitreoretinopathy of Grade C or more severe in 67% In conclusion, the overall success rate of consecutive vitrectomy in repaired ruptured globe was 87%. Prephthisical condition and severe proliferative vitreoretinopathy showed poor prognosis. We emphasize the necessity of well-planned vitreous surgery and the importance of its adequate timing in the management of penetrating injury.

A Case of Ocular Ischemic Syndrome

Ocular ischemic syndrome is an uncommon ocular condition occurring secondary to marked carotid arterial obstruction. It generally develops in older patients, in conjunction with entities associated with systemic artherosclerosis. We have currently encountered a case of monocular visual loss in a 65 year old patient who had a recent attack of cerebrovascular accident. Ocular examination revealed characteristic findings of chronic ischemia, including corneal edema, rubeosis, anterior uveitis, progressing cataract, retinal arterial narrowing, venous irregular dilatation and scattered retinal hemorrhages. Diagnosis was made by the fluorescein angiographic findings of prolonged retinal circulation time and diffuse capillary non perfusion as well as by carotid MR-Angiographic finding of complete obstruction of internal caratid artery.

Corneal Epithelial Wound Healing After Excimer Laser Photorefractive Keratectomy

We studied the effects of three different treating methods on corneal repithelization after PRK such as pressure patch, therapeutic contact lens and collagen shield. The degree of pain among three different treating groups showed same results without difference. The postoperative corneal wound healing rate in collagen shield group was slower than the other groups at first day. The corneal wound healing duration in therapeutic contact lens was faster than the other groups. Therefore we could obtained the results that therapeutic contact lens treated group is clinically excellent method for accelerating corneal wound healing after excimer laser photorefractive keratectomy.
