The authors report the result of cryo-extraction of the lens in 50 eyes (44 cases) which were operated in B.N.D. Hospital from January 1978 to April 1980. The results are as follows: 1. The incidences of complication during operation were hyphema(8%), vitreous loss and rupture of the lens capsule(2%). Hyphema was the most common complication during operation. 2. The incidences of early postoperative complication were striate keratitis(26%), hyphema (2%), shallow anterior chamber(2%) and uveitis. 3. The incidences of late postoperative complication were vitreous prolapse into anterior chamber (6%), updrawn pupil(6%), macular edema(4%) and posterior synechia (2%), corneal degeneration with abnormal tissue growth into anterior chamber (2%), iris atrophy (2%) and vitreous opacity (2%). 4. The postoperative final visual acuity more than 0.5 were 37 eyes(74%) and less than 0.1 were 2 eyes(4%).

Choroideremia is a rare hereditary disease with characteristic fundus that causes night blindness and peripheral visual field loss. The authors encounter choroideremia accompanied by recurrent uveitis. This paper is designed to give a description of the condition, along with an investigation of the literature. Ophthalmological tests and treatments were performed. Characteristic fundus, night blindness, peripheral visual field loss, electroretinography and other manifestations led us to a diagnosis of choroideremia. The anterior uveitis was managed with medication.

This study is based on the results of cryo-extraction of the lens in 123 eyes(98 cases) which were operated in Chosun University Hospital between Jan. 1979 and Feb. 1981. The results are summarized as follow: 1. The cryo-extraction have been done for 41 males and 57 females of the 98 patients. 2. The incidences of complication during operation were capsule rupture (5.7%), vitreous loss (4.9%), iris prolapse (1.6%). 3. The incidences of early postoperative complication were hyphema (12.1%). updra wn pupil (8.9%), corneal edema (6.5%), flat anterior chamber (4.9%). 4. The incidences of late postoperative complication were vitreous bulging (5.7%), vitreous opacity (4%), glaucoma(2.4%), uveitis (0.8%), retinal detachment (0.8%). 5. The ccrrected visual acuities before discharge of hospital were: more than 0.5 ... 39.0% (48 eyes), 0.1-0.4 ... 48.8% (60 eyes), less than 0.1 ... 12.2% (15 eyes). 6. The major causes of visual acuity less than 0.1 were vitreous opacity (33.4%), secondary glaucoma (20%), proliferative diabetic retinopathy (20%), corneal opacity (13.4%), retinal degeneration (13.3%).

This study was undertaken to evaluate the effectiveness of pars plana vitrectomy in pars planitis and posterior uveitis. We performed pars plana vitrectomies in consecutive series of 31 eyes with pars planitis and posterior uveitis that were complicated with vitreous opacities, epiretinal membrane formation, tractional retinal detachment and posterior subcapsuIar cataract. Postoperatively improvement of visual acuity, 2 lines or more in Snellen chart, was noted in 19 eyes (61.2%) with a mean follow-up of 21 months. The inflammatory cells were not visible in anterior chamber or anterior vitreous after 1 month thereafter. In three patients, however, the postoperative visual acuities were worse due to preoperatively combined cystoid macular edema, macular pucker and tractional retinal detachment. We believe early pars plana vitrectomy before the formation of epiretinal membrane is an important factor in minimizing and postoperative complications.

Posterior chamber intraocular lenses were implanted into 40 eyes with inadequate capsular or zonular support by securing both haptics of the lenses to the sclera at ciliary sulcus with 10-0 prolene sutures. Our follow-up of 36 eyes with scleral fixated posterior chamber intraocular lenses ranged from 2 months to 8 months(average 4.6 months). At the last follow-up visit. 31 eyes(86%) had a vision of 0.5 or better. Mean refractive error was -1.15 +/- 1.13D. which was -0.67 +/- 0.99D more myopic than predicted (p<0.05). Measurement of anterior chamber depth showed deeper than the control group of posterior chamber intraocular lenses without scleral fixation suture(4.18 +/- 0.42mm, 3.96 +/- 0.29mm, respectively), but which was not statistically significant(p>0.05). Additionally, the difference of postoperative axial length between two groups was not statistically significant(23.39 +/- 0.87mm, 23.42 +/- 0.75mm, respectively). In 4 eyes(ll %), minor intraoperative bleeding oceured but was absorbed spontaneously without any sequelae. One eye(3%) of minimal decentration of PCL, one eye(3%) of subluxation of PCL, and one eye(3%) of exposed scleral fixation suture were noted, but no serious postoperative complication, such as corneal edema, glaucoma, persistent uveitis, or retinal detachment was detected.

The viscoelastic substance has been used popularly in trabeculectomy. Hence, the authors compared the safety and postoperative influence in viscoelastic substance use group with non-use group in trabeculectomy. The authors evaluated 20 eyes of 10 open-angle glaucomatous patients undergoing trabeculectomy who had had no systemic disease, no ocular trauma history, and over 21 mmHg intraocular pressure though over 2 eye drops and over one time p.o. medications a day. One eye of these patients used viscoelastic substance(Viscoat(r), Alcon, U.S.A.)and the other did not. The authors measured intraocular pressure and anterior chamber depth at postoperative 1 day, 3 days, and 7 days and measured corneal endothelial cell numbers at preoperative and postoperative 1 month and examined complications such as anterior chamber hemorrhage, anterior chamber inflammation and cataract progression. Viscoelastic substance did not influence intraocular pressure, anterior chamber formation and corneal endothelial cell damage postoperatively in trabeculectomy(p>0.5). But as complications, intraoperative iris prolapse in two eyes, postoperative anterior chamber hemorrhage in a eye, and postoperative cataract progression in a eye developed and anterior chamber inflammation was also worse in the non-viscoelastic substance use group. Conclusively, the viscoelastic substance would reduce intraocular tissue damage, make intraoperative bleeding control easy and prevent anterior chamber collapse immediately after operation in trabeculectomy. Because only open angle glaucoma was studied in the present research, further study was applied to acute angle closure glaucoma, neovascular glaucoma which is apt to bleed, and glaucoma with cataract or uveitis in which intraoperative intraocular damage is minimized.

We report a case of recurrent occlusion of laser iridotomy (LI) sites after a Visian ICL (Implantable contact lens version 4, Staar Surgical AG, Nidau, Switzerland) implantation. A 45-year-old woman had bilateral ICL implantation after placement of two peripheral LI sites in each eye to prevent pupillary block. At one month after the operation, severe narrowing or occlusion of four LI sites occurred. After this, although she received four additional LIs at postoperative months 1, 6, 9 and 10 in both eyes, the narrowing or occlusion recurred. Mild chronic anterior chamber inflammation was observed intermittently throughout the follow-up period. We performed clear lens extraction in both eyes (at postoperative month 11 in the left eye and month 26 in the right eye) due to recurrent occlusion of the LI sites and excess trabecular meshwork pigment deposition presumably caused by the four repeated LIs. Recurrent obstruction of LI sites can occur after ICL implantation. These problems were unresolvable despite four repeated laser iridotomies. The risks associated with anterior uveitis must be considered when planning an ICL implantation.

The authors wish to report a case of bilateral acute anterior uveitis and optic disc edema following a hemotoxic snake bite, in order to highlight the concomitant occurrence of these conditions and the potential adverse effects of anti-snake venom (ASV). A 35-year-old male was bitten by a viper at seventeen thirty hours, and was started on ASV. Two days following treatment he experienced sudden onset redness and painful diminution of vision in both eyes (OU). On examination, the patient's visual acuity (VA) in OU was 20/200. Examination revealed fresh keratic precipitates, cells, and flare in the anterior chamber (AC), posterior synechiae, sluggish and ill-sustained pupillary reaction, and hyperemic, edematous disc with blurred margins in OU. He was started on topical steroids, cycloplegics and intravenous methylprednisolone. Following treatment, the patient showed improvement and was continued on topical medications and oral prednisolone tapered over 3 weeks, after which VA OU improved, the AC showed no cells and flare and disc edema resolved. Uveitis and optic disc edema in snake bite can either be due to the direct toxic effects of the venom or the effect of ASV. Steroids have a beneficial role in the management of these symptoms.
