Dal Jun CHUNG ; Soo Hwan CHOI ; Shin Dong KIM

Journal of the Korean Ophthalmological Society.1993;34(11):1183-1187.

Retinal toxicity secondary to intravitreal injection of gentamicin for the purpose of prophylaxis or treatment of endophthalmitis was reported infrequently and it was thought to be caused by an error in the intravitreal injection technique or by faulty dilution of gentamicin. After vitrecotomy, we experienced two cases of ischemic retinopathy secondary to intravitreal injection of gentamicin for prevention of endopthalmitist.

Sang Ho SEO ; Han Ki CHANG

Journal of the Korean Ophthalmological Society.1993;34(11):1178-1182.

We performed simple and successful canalicular reconstruction with smooth tip pigtail probe in 56 cases of inferior canalicular laceration. After general anesthesia or local anesthesia in inferior and superior canthal area, upper lacrimal sac area and lacerated inferior eyelid, methylcellulose mixed fluorescein was injected through the superior canaliculus under the surgical microscope with cobalt blue filter and simply found cutting end of the inferior canalicullus. Smooth tip pigtail probe was inserted and silicone stent was connected the superior and inferior canaliculi and the peri canalicular sheath was sutured with and to end anastomosis. Silicone tube was removed after postoperative 8 weeks and 86% of the patients(48/56 cases) was successful without epiphora. Smooth tip pigtail probe, methylcellulose mixed fluorescein, silicone stent, and end to end anastomosis of pericanalicular sheath under the surgical microscope would increase the success rate of pigtail probe canalicular reconstruction.

Compliance of Patching Theraphy for Amblyopia.

Gyeong Hwan ROH ; Yoonae A CHO

Journal of the Korean Ophthalmological Society.1993;34(11):1171-1177.

Good compliance of patching therapy is essential to improve visual acuity in amblyopia. The author investigated the compliance and effective method of occlusion therapy for amblyopia by questionair given to the patients and their parents. For better compliance and the duration of patching and the best time for its performance should be controlled according to patients' character and age. It was shown that the younger the age, the better the compliance of patching therapy. It was important that early diagnosis for amblyopia made and early treatment should be initiated before 6 years of age, beeause the compliance of patching therapy was much decreased in patients above six years of age. Physicians should ensure full understanding of amblyopia in patients and their parents, especially mothers, before patching therapy begins. Continued and steady patching could considerably improve visual acuity in ehildren older than eight years of age.

Min Jong PAIK ; Jung Eon YANG ; Joo Hwa LEE

Journal of the Korean Ophthalmological Society.1993;34(11):1167-1170.

Canalicular occlusion with silicone plug was carried out in 11 patient, 21 eyes with dry eye syndrome and the effect and safety of the procedure were evaulated. Artificial tears were discontinued or frequency of instillation was reduced in 66.6% of eyes after occlusion of canaliculi. There were no stastiscally significant differences in the mean value of B.U.T. and Schirmer test pre-and post-canalicular occlusion. There were no cases of postoperative epophora, allergic reaction and infection.

Oh Woong KWON ; Joon Sang KIM ; Young Jac HONG ; Hong Bok KIM

Journal of the Korean Ophthalmological Society.1993;34(11):1162-1166.

Sudden loss of visual acuity and visual field can occur in the vast majority of BRVO patients. One third to half of the patients recover from impared cision even without specific treatment, but it is unlikely when complication such as macula edema, capillary nonperfision, neovascularization and vitreous hemorrhage are accompanied. The authors reviewed 55 patients with branch retinal vein occlusion(55 eyes) in regard of the size of capillary non perfusion, and divided them into two groups; the perfused group(15 eyes) in which the area of capillary non perfusion is less than 5 disc diameter, and the nonperfused group(40 eyes) in which the area is more than 5 disc diameter. The freqnency of the development of neovascularization and vitreous hemorrhage, and the final visual outcome between two groups were compared. Neovascularization occurred in 3 eyes of perfused group and 23 eyes of nonperfused group, and vitreous hemorrhage occured in 4 eyes of nonperfused group, and vitreous hemorrhage occurred in 4 eyes of nonperfused group. There was no statistic al difference between two groups in the final visual acuity.

Jong Moon PARK ; Hyeong Seog SHIM ; Ji Hong BAE

Journal of the Korean Ophthalmological Society.1993;34(11):1154-1161.

Authors analysed the clinical characteristics and the surgical results of rhegmatogenous retinal detachment in 70 patients(71 eyes) who were operated GNUH from Feb. 1990 to Feb. 1992. The clinical characteristics of rhegmatogenous retinal detachment were as follows. The result was myopia(39.4%) as the most common associated ocular finding, one break(57.7%) as the number of break, two quadrants(33.8%) as the extent of retinal detachmenthole(53.5%) as the type of break and superior temporal portion(56.3%) and anterior portion including equator(83.1%) as the location of break. The success rate of first operation was 87.3% and the overall success rate of rhegmatogenous retinal detachment maintained anatomical attachment above 6 months and exeluded 3 cases of refused reoperation was 92.3%. The type of break extent of detachment and duration of detachment were not influenced to surgical success rate statistically(P>0.05). The most common cause of first operative failure was proliferative vitreoretinopathy(57%).

Ultrastructural Study on Basement Membrane Thickening of Iris Capillaries in Diabetic Patients.

Jun Seok TAE ; Jung Hyub OH ; Oh Woong KWON

Journal of the Korean Ophthalmological Society.1993;34(11):1148-1153.

The early ultrastructural changes of basement membrane thickening and degeneration of the pericyte were noted in retinal capillaries in diabetic patients. However no early ultrastructural changes were reported in diabetic iris capillary. The authors studied the ultrastructural features of basement membrane of iris capillaries which were obtained during cataract surgery in five diabetic patients and compared with those obtained in five nondiabetic patients. The endothelium basal lamina, pericyte basal lamina and membrane-like pericyte matrix in didabetic iris capillaries were thicker than those in nondiabetic Iris capillaries. The thickening of pericyte basal lamina is more prominant than the endothelium basal lamina in diabetes. The duration of diabetes had no relationship to endothelium basal lamina but, showed statistically significant relationship to thickness of pericyte bascal lamina and pericyte matrix.

Electronmieroscopic Findings of the Rat Retina Following Intraperitoneal Injection of 2,4-Dichlorophepoxyacetie Acid.

Min Jong PAIK ; Jin Hyung YOO

Journal of the Korean Ophthalmological Society.1993;34(11):1141-1147.

2,4-Dichlorophenoxyacetic acid is a component of agent orange, which was spread during Vietnam War. Due to the toxicity of this agent, several diseases may be occuring today, potentially causing social problem. The author tried to take as preliminary information for a further clinical study by examining whether 2,4-dichlorophenoxyacetic acid makes any change in the retina of a white rat histopathologically. The objects were 6 white rats of 200-300 gm in weight. After diluting 40% 2,4dichlorophenoxyacetic acid, it was injected intraperitoneally into the rats at the levels of 5 mg/kg, 10 mg/kg, 15 mg/kg of agent. The eyeballs of the each groups were enucleated on 24 hours and 3 days and examinated with an electron microscope. Histopathological changes in the retina were characterized by the degeneration of the retinal pigment epithelial cells, the photoreceptor cells, and the choriocapillaris. To prove that 2,4-dichlorophenoxyacetic acid injures human retina, experiments with futher various plans and epidemiological surveys should be provided.

Clinical Effect of Tissue Plasminogen Activator in Vitreous Hemorrhage.

Young Woo IM ; Jung Il MOON ; Sang Moon JUNG

Journal of the Korean Ophthalmological Society.1993;34(11):1135-1140.

There has been several reports that tissue plasminogen activator(tPA) accelerated the fibrinolysis in vitreous cavity in-vivo. We investigated the efficacy of intravitreal tPA injection(25 microgram/100 microgram, 0.1 ml) for treatment of vitreous hemorrhage in non-vitrectomized patients(58 patients, 61 eyes). 1. Visual acuity was improved in 43 eyes(70.5%) and fundus was relatively well seen in 29 eyes(47.5%). 2. There were no clinical differences of intraocular pressure between before injection and the day after injection of tPA. 3, The complication of tPA injection were rebleeding(3 eyes, 4.9%) and inflammatory reaction(1 eyes, 1.6%). On these results, it appears that intravitreal tPA injection is useful for treatment of vitreous hemorrhage before vitrectomy.

Intraocular Pressure Change Following Cataract Surgery in Patient with High Intraocular Pressure.

Gi Bok GO ; Dong Won KIM ; Nam Ho BAEK

Journal of the Korean Ophthalmological Society.1993;34(11):1128-1134.

We retrospectively evaluated change of the intraocular pressure(IOP) after extracapsular cataract extraction with posterior chamber intraocular lens insertion without a filtering procedure in patients who have had high IOP preoperatively. The study included 1geyes of 15 patients with a mean age of 57 years. The follow-up period ranged from 3 months to 24 months(average 7 months). Their mean preoperative IOP was 19.35 mmHg and was 14.29 mmHg about seven months after operation. The mean reduction of rap was 5.06 mmHg(26%). Mean IOP reduction was 4.82 mmHg(25%) in open-angle glaucoma and 6.09 mmHg(32%) in angleclosure glaucoma. In this study 15 of 19 eyes(79%) required glaucoma medication preoperatively. However, 6 of 15 eyes(40%) required a smaller number of medication postoperatively. Postoperatively, 18 of the 19 eyes of 95% achieved 0.6 or better visual acuity. One eye with visual acuity 0.2 was not improved due to diabetic retinopathy. Complications during surgery were not detectable. But immediate postoperative complications included hyphema(1 eye), prolonged punctate keratitis(2 eyes), cyclitic membrane(1 eye), and coneal abrasion(1 eye).
