[The importance of a study of the tears in the early diagnosis of infection in penetrating eye injuries].

Status of tears was studied in patients with penetrating wounds to the eyes using polarization optic microscopy to assess the type of morphological types of crystals, measurements of secretory IgA to assess local immunity status, and screening methods to estimate protein level from the relative coefficient. A total of 122 patients with penetrating corneal and corneoscleral wounds were examined, 48 of these without clinical signs of infection and 74 with clinical manifestations of an infection. For control 88 subjects without somatic diseases or ocular diseases were examined. Crystallography revealed predominance of two morphologic types, Nos. 3 and 5, whose crystal structures were taken as the normal types. Their detection rate was reduced in penetrating wounds to the eye. Secondary morphologic types Nos. 14 and 16 reliably predominated in "pure" injuries and a secondary morphologic type 14 M in patients with developing infection (in 19 patients this type predominated during the preclinical form of infection of the eye). Increased IgA levels were observed in patients with noninfected injuries and reduced ones during infection. An infection was found associated with reduced protein level.

Eye injuries from merchandise display hooks.

PURPOSE/METHODS: Four patients had ocular or ocular adnexal injuries, which resulted from store merchandise display hooks. RESULTS/CONCLUSIONS: Ocular and periocular injuries from display hooks include conjunctival, eyelid, and canalicular lacerations, as well as penetrating brain injury. Display hooks are commonly used in retail establishments and pose a high risk when placed below eye level.

The role of scleral buckle in experimental posterior penetrating eye injury.

PURPOSE: Although episcleral buckles are frequently placed as an additional procedure to vitreoretinal surgery, little is known about their independent effect after ocular trauma. The authors created a posterior penetrating ocular injury model to evaluate the isolated role of primary episcleral buckle placement. METHODS: Twenty eyes underwent surgery. The penetrating injury consisted of two 5-mm circumferential incisions placed five clock hours apart and 8 mm behind the limbus. A segmental episcleral buckle was placed over a randomly chosen injury site after wound closure. The degrees of fibrous proliferation, traction, and the presence of retinal detachment were evaluated on follow-up examinations. After enucleation and initial fixation, tissue sectioning was performed, and the greatest dimension of the fibrous proliferation at both wound sites was measured with a caliper. RESULTS: Two eyes were excluded from the study. Three eyes developed a retinal detachment; the remaining 15 eyes showed varying degrees of proliferation and traction on the retina. The greatest dimension of the fibrous proliferation at the buckle site (1.22 +/- 1 mm) was significantly different from that at the nonbuckle site (2 +/- 1.45 mm, P = 0.01). CONCLUSIONS: Primary episcleral buckle placement at the time of surgical repair reduces vitreous traction from the buckle site and decreases the degree of fibrovascular proliferation.

Epidemiology of severe eye injuries in childhood.

The authors conducted a cross-sectional study of all ocular injury cases admitted to a children's hospital between January 1978 and December 1984. Of 222 injuries reviewed, 77 (35%) resulted in some visual deficit. Males were significantly overrepresented in all age groups with an average male:female ratio of 3.5:1. The distribution of injuries was: contusions, 114 (51%); penetrating lacerations, 62 (28%); foreign bodies and burns, 11 (5%); and nonpenetrating lacerations, 35 (16%). Sixteen (7%) ocular injuries were associated with BB gun pellets and six of these children (42%) were blinded in the injured eye as a result. Two other cases of blindness resulted from ocular penetration by homemade "Jinsang Stars," underscoring the adverse influence of media on children's games. Adult supervision could have potentially prevented most cases of permanent visual deficit. The authors suggest that legislation restricting the use of BB guns be passed and that a program of adult and child eye safety education including "eye watch" warnings on potentially hazardous toys be developed.

[Possibilities of intracapsular implantation of intraocular lenses in eye injuries].

The authors analyze the results of 63 surgeries for implantation of intraocular lenses, V. N. Alexeyev's design, in patients with traumatic cataracts and other injuries after perforating and contusion injuries. The results evidence a high efficacy of intracapsular implantation. Vision acuity with correction has improved in 36 eyes to make up 0.5 and more diopters. In the rest cases (27 eyes) vision acuity with correction has made up 0.1-0.4. The implantation was simple and the course of the postoperative period smooth in the patients with membranous and semiresolved cataracts, with primary and secondary glaucoma, and implantation into the posterior chamber.
