PURPOSE: To determine the difference among the results of three kinds of methods for the treatment of simple retinal detachment. METHODS: We analyzed the patients undergoing primary pars plana vitrectomy(Group I: January to June, 1997), scleral buckling(Group II: January to June, 1996) and pneumatic retinopexy(Group I: January to June, 1995) to treat simple retinal detachments with retinal breaks located in peripheral retina, smaller than one clock hour, breaks in the superior eight clock hours, multiple breaks extending less than two clock hours and no severe retinal traction. RESULTS: The final visual acuity was 5/200 or more(functional success) in 19 eyes(100%) of Group I, 19 eyes(100%) of Group cII and 20 eyes(90.9%) of Group I. Primary retinal reattachment(anatomical success) was in 17 eyes(89.5%) of Group I, 19 eyes(100%) of Group II and 18 eyes(81.8%) of Group I with no statistically significant difference among the three groups. The final retinal reattachment rate was 100% in all groups. CONCLUSIONS: This result suggests the scleral buckling might be a little bit better for the treatment of simple retinal detachment, though each of three surgical methods showed no statistical difference of functional and anatomical results.

The Rieger's syndrome is characterized by the ocular anomalies include posterior embryotoxon(a prominent Schwalbe's line), tissue strands across the anterior chamber angle and variable degrees of iridic distortion and systemic defects most often involve the teeth and facial bones. These disorders are typically bilateral, are usually diagnosed at birth or in early childhood, and most have genetic basis of autosomal dominant inheritance. A large number of patients have glaucoma due to developmental defects of the anterior chamber angle structures. The authors experienced two cases of Rieger's syndrome which were occurred in a 13-year-old female in one family and in a 21 year-old male in the other family who had characteristic ocular and other systemic abnormalities associated with developmental glaucoma.

The authors experienced a case of the monomorphic adenoma of lacrimal gland. Monomorphic adenoma is an extremely rare salivary gland tumor. A fifty eight year old Korean female was admitted to our Dept. of Ophthalmology because of multiple small nodular masses on her right upper eyelid and a large hard solitary mass in the supraorbital area since one year ago. On B-scan ultrasonogtaphy, round echo-free zone was detected in the superiortemporal orbit. Well defined hyperdense, enhanced round extraconal mass in the superiororbital area was detected by orbital CT scan. Two large well encapsulated, dark brown colored masses were extracted by supraorbital approach and lateral orbitotomy under general anesthesia. After removal of the masses, histopathologic examination confirmed the lacrimal monomorphic adenoma.

We performed vitreous surgery for stage 3 or 4 idiopathic macular holes and assessed the efficacy of basal retinal pigment epithelial scraping in postoperative healing of macular holes. Twelve eyes of 12 patients were included. Mean duration of symptom was 12.75 months and mean age was 65.7 years. 9 patients(75%) were female and three eyes(25%) had macular holes larger than 1/3 disc diameter. The preoperative visual acuity was 0.1 or worse in eleven eyes(92%). Postoperatively, hole closed in ten eyes(83%) and the visual acuity improved two line or more in all eyes(100%) with mean follow-up time of 12.8 months. In 5 eyes(42%), the visual acuity improved 0.3 or better. Anatomical success seemed to be related to the preoperative hole size, which statistically had no significant relationship(p=0.0593). Retinal pigment epithelial alteration was notified in three eyes(25%). This result suggests retinal pigment epithelial scraping may become adjunctive therapy in macular hole surgery and, however, care has to be taken to prevent from inducing retinal pigment epithelial alteration.

PURPOSE: To determine the clinical characteristics and visual prognosis of intraocular foreign bodies (IOFBs). METHODS: We analyzed the patients with surgical removal of IOFB and follow-up of 4 months or longer. RESULTS: Of all 126 eyes of 126 patients, 118 patients (93.6%) were men and mean age was 42.7 years. The cause was lawn mower in 49 eyes (38.9%). Metal composition was in 114 eyes (90.5%), corneal inlet was present in 101 eyes (80.2%) and posterior location was in 97 eyes (73.0%) were there. Visual acuity was worse than 0.04 in 77 eyes (61.1%) before operation and in 36 eyes (28.6%) at the final visit. The final visual acuity was significantly related with initial visual acuity (criterion: 0.1, P=0.001), wound length (criterion: 3 mm, P< 0.001), location (anterior vs. posterior location, P< 0.001) and size (criterion: 3mm, P< 0.001) of IOFB, traumatic cataract (P=0.011), vitreous hemorrhage (P=0.001) and retinal tear (P< 0.001), respectively. CONCLUSION: Lawn mower is the main cause of IOFB and the countermeasure should be needed for it. Initial visual acuity, location and size of IOFB, wound length, vitreous hemorrhage and retinal tear may be the important factors on visual prognosis of IOFB.

We evaluated the relationship between the surgical success of idiopathic macular hole and sex, age, duration, epiretinal membrane, preoperative visual acuity, size of the hole, and surgical method. Of all 25 eyes in 23 patients, 14 eyes(56%)showed anatomical success(disappearance of the hole), and 17 eyes(68%)functional success(the final visual acuity of 0.15 or more with more than one line improvement). There were statistically significant differences of anatomical(p=0.001)and functional success(p=0.020)between the Group I where its macular hole was less than one-fourth of the optic disc in size and the other group, and anatomical success(p=0.039)between the group with the age of less than 70 years(Group A)and the other group. In Group I, anatomical and functional success were both 92%(11 eyes/12 eyes). In Group A, anatomical and functional success were 72%(13 eyes/18 eyes)and 77%(14 eyes/18 eyes), respectively, and there was statistically significant relationship between size of the hole and anatomical success(p=0.024), and difference of anatomical success between the group with duration of less than 6 months and the other group(p=0.023). Good surgical result may be expected in the idiopathic macular hole of the age of less than 70 years with about 350 micrometer or less in size and duration of less than 6 months.

Adenosine deaminase(ADA)has been used for the diagnosis of localized tuberculosis.The titer of ADA was measured from the ocular fluid of the patients who had undergone vitreoretinal surgery due to non-tuberculous vitreoretinal disease. Forty five patients were included and twenty patients were male. Mean age was 51.9 years. Four patients had diabetes mellitus and two had essential hypertension. The most frequent cause of vitreoretinal surgery was proliferative vitreoretinopathy(12 eyes). For the analysis of ADA titer, vitreous fluid(group I)was aspirated in 36 patients undergoing pars plana vitrectomy and subretinal fluid(group II)in 9 patients undergoing scleral encircling. Mean titer of ADA was 9.01+/-15.69 IU/L, and there was no significant difference on the statistics between group I(6.06+/-13.75 IU/L)and group II(20.83+/-18.17 IU/L). All 45 eyes showed negative reaction to polymerase chain againt tuberculosis, and 25 of 29 patients had positive reaction to tuberculin skin test. There was no statistically significant relationship between ADA titer and tuberculin skin test. This result suggests that ADA may be used for the diagnosis of posterior ocular tuberculosis, since the normal concentration in the posterior ocular fluid was compatible with the one in other body fluids where it has been used for the diagnosis of localized tuberculosis.

Trabeculectomy with mitomycin C was performed on three patients with traumatic dislocate crystalline lens and refractory secondary glaucoma, combined with pars plana vitrectomy, intravitreal phacofragmentation and scleral fixation of the IOL. Over nine months after operations, intraocular pressures were well controlled not only without any antiglaucomatous medications and special complications but also with good visual recovery in all patients . Trebeculectomy combined with pars plana vitrectomy may be useful in some patients wit hvireoretinal disease and glaucoma.

Result and complications were evaluated in 28 eyes of 28 patients who had undergone pneumatic retinopexy for rhegmatogenous retinal detachment from December 1994 to May 1995 and were followed for at least 4 months. Twenty four eyes were phakic, one eye aphakic and three eyes pseudophakic. 0.3mlof perfluoropropane(4 eyes)or 0.45ml of sulfur hexafluoride(24 eyes)was injected. Mean follow-up time was 33.3 months. Perioperative complications included subconjunctival gas in 2 eyes, subretinal gas in 1 eye and delayed absorption of subretinal fluid in 5 eyes. Retinal reattachment was obtained in 22 eyes(79%) and final reattachment rate was 100% with an additional procedure of scleral buckle(4 eyes)or pars plana vitrectomy(2 eyes). Final visual acuity improved in 25 eyes(89%), and decreased in 2 eyes. Postoperatively following complications were noted;mild proliferative vitreoretinopathy(3 eyes), epiretinal membrane(1 eye), central retinal artery occlusion(1 eye), nucleosclerosis(4 eyes)and cataract operation(2 eyes). This result suggests that pneumatic retinopexy could be a good method for the treatment of rhegmatogenous retinal detachment.

CHAP syndorme consists of choreoathetosis, orofacial dyskinesia, affective change, hypotonia, and pseudobulbar signs. CHAP syndrome was firstly des- cribed with onset 1 to 7 days after induced profound hypothermia and complete circulatory arrest for con- genital heart lesion repair. Since then, only a few cases have been reported until now. Case We report a patient who demonstrated all of the elements of the CHAP syndrome in severe cachexic state. Brain SPECT(99mTC-ECD) shows decreased perfusion in left fronto-parieto-temporal lobe. Comments The pathogenesis of CHAP syndrome is obscure. However our case led us to suggest that more essential component pre- disposing to the CHAP syndrome is hypoxia rather than hypothermia. Furthermore, it seems to be related with circulatory insufficiency in extrapyramidal nervous systems.
