Use of Tissue Adhesives in Experimental Porterior Fixation Suture

Inadvertent perforation of the globe, granuloma and hypersensitivity reaction have been recognized complications of the strabismus surgery. We performed experimental strabismus surgery with No.240 retinal band and histoacryl(group I), histocracyl only(group II), 6-0 vicryl(group III) in rabbit model to determine whether these techniques can replace the classic suture and decrease its complications. We measured maximum adhesion power by force gauge and observed histopathologic findings after sacrificing four rabbits at 1 day, 1 week, 4 week, and 8 weeks, respectively following experimental strabismus surgery. There were chronologically increasing tendency of adhesion power in all groups but no statistically significant differences among three groups. Pathologically inflammatory and foreign body reactions were decreased with time and there were no differences of inflammatory reactions among three groups. At four weeks after the experiment, there was encapsualation lined with loose fibrous tissue around the band in group I.In conclusion, We found that experimental strabismus surgery with tissue adhesives and No.240 retinal band showed good adhesion power and minimal tissue reaction. So, it is possible to do posterior fixation suture with tissue adhesive and No.240 retinal band in classic strabismus surgery.

Triple Procedure for Phacoemulsification, Foldable IOL Implant and Trabeculectomy with Mitomycin-C

The purpose of our study is to evaluate the visual, refractive and IOP results following combined small incision phacoemulsification, foldable lens implantation, and fornix based trabeculectomy with Mitomycin-C. Seventy-six eyes of 64 patients with cataract and glaucoma had undergone the combined procedure. Minimal follow-up period was 6 months(mean 12.8+/-4.8 months). All the eyes that were free of preexisting macular disease and endstage glaucomatous optic nerve damage demonstated significant improvement in visual acuity. Postoperative astigmatisn was negligible(-0.41diopters). The average IOP reduction was 7.7mmHg. Functioning filtrating bleb persisted in 76.3% of the eyes. Complications with this method were not significant compared with other studies reporting the combined procedure. The small incison phacotrabeculectomy with mitomycin-C technique that we describe appears to be effective in early restoration of visual acuity and reduction of IOP without significant complications.

Intraocular Foreign Bodies by Power Lawn Mowers

Power lawn mower is a useful equipment for landscape, but it can introduce a new eye trauma. These ocular injuries are recently increasing in Korea. To inform the possibility of visual loss, we reviewed medical records of 11 patients with intraocular foreign bodies by power lawn mowers. All of patients were men and lawn mower operators themselves. Nature of foreign bodies was metallic in 10 eyes(91%), Inlet was through the cornea in 10 eyes(91%), and intraocular location was at the vireo retina in 8 eyes(73%). At final follow-up, best corrected visual acuities were worse than counting fingers in 4 eyes(36%). Safety cover or halmet is needed for prevention of eye trauma caused by power lawn mower, however, more important, operators themselves should follow the ordinary safety rules.

Clinical Study on Primary Acute Angle Closure Glaucoma

In order to study the clinical characteristics of primary acute angle closure glaucoma, we analyzed the data of 72 eyes from 63 patients with the disease from January 1, 1990 to December 31, 1993 to the Department of Ophthalmology of Chonnam University Hospital. The mean age of the patients was 63.3 years and female and male ratio was 5.9:1. And the mean IOP at first visit was 53.2 mmHg. There was no significant difference of rop between right and left eyes, and 11 patients had the disease in both eyes. 38% of the patients developed the disease in winter time. The development of the disease was closely associated with physical illness and emotional stress. 39 eyes(49.3%) of them was required filtering surgery because medication and laser treatment was insufficient to lower IOP.
