M-mode, pulsed Doppler and Doppler color flow mapping, in addition to two-dimensional echocardiography, have greatly improved imaging of the fetal heart through identification of abnormal cardiac anatomy and rhythm in utero. The early detection of cardiac disturbance in utero permits alteration in obstetric management such as delivery in a high-risk center for optimal neonatal care and/or decision in optimal delivery time. We report two cases of the neonatal arrhy-thmia which were observed by fetal echocardiography. In the first case, female baby showed neonatal arrhythmias including tachycardia and brady-cardia until 3 days after birth, and then turned to bradyarrhythmia due to non-conducted atrial bigeminy. These events lead us to review the fetal echocardiographs of the patient carefully. Premature atrial contractions were observed in her fetal echocardiography. At 2 months after birth, the patient's electrocardiogram showed normal sinus rhythm. Severe neonatal bradycardia of the second case was due to congenital complete heart block, identified clearly by electrocardiogram after birth. This case also showed complete heart block in her fetal echocardiography. After insertion of the temporary pacemaker, cardiomegaly was improved. Both the neonate and the mother had positive anti-SSA/Ro autoantibody. But any other symptoms and signs of neonatal lupus did not appear in the neonate. Patient's mother also did not show any symptoms and signs of systemic lupus erythematosus. Since the prognosis depends upon the cause of bradyarrhythmia in fetus and neonates, differential diagnosis is important in obstetric management and optimal neonatal treatment.

Trabeculectomy, as an operation precedure for glaucoman, decrease intraocular pressure(IOP)effectively. But the amount of decrease in IOP is different according to the etiology of glaucoma. Thirty four primary angle-closure glaucoma patients (37 eyes)who had undergone trabeculectomy only or trabeculecomy combined with cataract surgery and had been subsequently followed up for least 6 months, were enrolled in this study. In 12 patients(14 eyes) among 16 patients (18 eyes, Group 1) who had undergone trabeculecto-my only, IOP was controlled without glaucoma medication, while glaucoma medication was needed in the other 4 patients (4 eyes). Among 18 patients (19 eyes, Group 2) who had undergone trabeculectomy combined with cataract surgery, IOP were controlled without glaucoma medication 9 patients (10 eyes); controlled with medication in 8 patients (8 eyes); and not controlled even with 1 patient (1 eye). The amount of decrease in IOP was no statistically different between the two groups. Group 2 had deeper anterior chamber than Group 1 (p<0.01). The above results suggest that the combined pro-cedure may benefit in primary angle-closure glaucoma patients, especially old complicated patients.

A 4-year-old boy has had a solitary sclerotic depressed plaque on the right anterior chest since birth. The histopathologic findings are consistent with morphea profunda: thickening, hyalinization, and homogenization of collagen bundles in the dermis and subcutaneous tissues, admixture with a prominent lymphocytic and plasma cell infiltrate, and sweat glands en-trapped between the thickened collagen bundles. We report a case of congenital solitary morphea profunda.

4.Effectiveness of Argon Laser Peripheral Iridoplasty in the Treatment of Severe Acute Angle-Closure Glaucoma.
Journal of the Korean Ophthalmological Society 1998;39(4):715-720
We used argon laser peripheral iridoplasty to reduce intraocular pressure[IOP] in acute angle-closure glaucoma[ACG] which is unrelieved by medical and physical treatments and could not be treated by peripheral iridotomy due to edematous cornea and turbid aqueous. Eight of 16 eyes [16 patients] were successfully treated. These successfully treated eyes had a mean duration of angle closure of 4.1 days and 8 unsuccessfully treated eyes 9.2 days. The 6 eyes of 8 eyes with successful reduction of IOP after argon laser peripheral iridoplasty were treated peripheral iridotomy at average 1.7 day later and had deep anterior chamber. After a mean follow-up period of 2 months, 7 of these 8 successfully treated eyes had an IOP less than or equal to 21mmHg. Argon laser pripheral iridoplasty may be successful in treating ACG which is unrelieved by medical and physical treatments and could not be treated by pripheral iridotomy, especially in cases that are recognized and treated soon after onset.

Advancement of a fornical conjunctival flap is the method used for bleb reconstruction after excision of necrotic leaking bleb. The authors have experienced a case of corneal bleb at 4 months after necrotic leaking bleb excision and advancement of fornical conjunctiva. The patient complained of irritation. The authors sutured conjunctival bleb over the cornea tightly to the limbus with full corneal thickness. Postoperatively corneal bleb and irritation symtom disappeared and visual acuity improved, but at postoperative 1 month, small corneal bleb recurred, which was punctured with 26G needle and Nd: YAG laser. Subsequently it disappeared and did not recur.

The authors studied retrospectively the results of mitomycin C (MMC) trabeculectomy in 19 eyes with neovascular glaucoma which could be followed up more than 4 months after surgery. Twelve eyes(63%) were classified as success group and 7 eyes(37%) were classified as failure group. In the success group, the mean intraocular pressure(IOP) was significantly reduced from 52.1+/-10.1mmHg preoperatively to 10.1+/-3.8mmHg at last follow Kaplan-Meier survival analysis, cumulative success rates at 6 and 12 months intervals were 68%, 59% respectively. In the failure group, the mean IOP was reduced significantly from 51.9+/-8.1mmHg preoperatively to 26.6+/-13.4mmHg at last follow up. The mean number of medications to reduce IOP was also reduced from 2.6+/-0.5 preoperatively to 1.3+/-0.8 at last follow up. The causes for failure were inadequate IOP control in 5 eyes(26%), loss of light perception in 1 eye(5%), and reoperation to reduce IOP(5%). Complication included hypotony in 4 eyes(21%), late bleb leakage in 2 eyes(10.5%), spontaneous hyphema in 2 eyes(10.5%), cataract progression needing extraction in 2 eyes(10.5%). We think that MMC trabeculectomy may be the first choice procedure before doing cyclocyro-therapry or cyclodestructive procedure using laser.

Mitomycin C has improved the success rate of glaucoma filtering surgery in patients at high risk for surgical failure. However chronic hypotony is marked by decreased vision and a late-onset leaking bleb after filtration surgery using mitomycin C. Bleb excision and conjunctival advancement is the method of choice to repair bleb leakage and chronic hypotony. Five eyes from five patients were received glaucoma filtration surgery with topical mitomycin C. All of the patients' blebs were avascular and transparent. The reasons for bleb excision were two spontaneous bleb leaks, two traumatic bleb leaks and one case of severe irritation. The mean follow-up period was 18.4 +/- 8.3 months (ten to 29 months). Cataract surgery was combined in one eye. Postoperative intraocular pressure (IOP) increased from 2.3 +/- 1.5 mmHg to 9.5 +/- 3.7 mmHg at nine months postoperatively in four eyes. It went from 28 mmHg to 40 mmHg in one patient with uveitis, for whom a second trabeculectomy with mitomycin C; 0.4 mg/ml for 3 minutes, was performed. After surgery, IOP decreased to 4 mmHg in three months. Postoperative visual acuity improved four snellen lines in three eyes. A partially avascular bleb recurred in three eyes, a corneal bleb in one eye and blepharoptosis, which disappeared spontaneously at four months postoperatively, in one eye. Necrotic bleb excision and advancement of fornical conjunctiva were useful methods to increase IOP and to improve visual acuity for the patient experiencing irritation symptoms, and for leaking blebs, and hypotonic maculopathy.

Since the anterior chamber tube shunt to an encircling band(ACTSEB) is not a simple procedure, an extended polytetrafluoroethylene (e-PTFE)-silicone tube (anterior chamber tube shunt to a surgical membrane; ACTSSM) was attempted as a new glaucoma drainage implant. To see whether the newly-modified, two-fold e-PTFE-silicone tube implant could prevent early hypotony and to compare the tissue response to each implant, ACTSEB and ACTSSM procedures were done in normal colored rabbit eyes. It was found the ACTSSM kept the depth of the postoperative anterior chamber normal. And in general, foreign body responses were light microscopically similar. The fibrous capsule lining the e-PTFE was composed of thicker, less dense fibroblasts, as well as less collagen than that lining the silicone encircling band. These findings seemed to be related to the difference in the pressure-lowering capacity between ACTSEB and ACTSSM.

10.Needle Revision with and without Mitomycin C for the Teatment of Failed Filtering Blebs after Trabeculectomy.
Journal of the Korean Ophthalmological Society 2006;47(7):1087-1092
PURPOSE: To evaluate the effects of needle revision (NR) with and without mitomycin C (MMC) for failed filtering blebs after trabeculectomy, and to identify risk factors for failure. METHODS: Thirty-one eyes whose intraocular pressure (IOP) did not decrease after cutting of scleral flap sutures were recruited. NR was performed with a 26-gauge needle under a slit-lamp. Immediately following NR, 15 eyes received subconjunctival injection of 0.002 mg (0.02 mg/ml) MMC at the adjacent conjunctiva. RESULTS: First NR was done at 1.3+/-1.2 months (range, 0.2~6.5 months) after trabeculectomy, and a mean of 1.6+/-1.6 NRs per patient were done. The follow-up period was 24.4+/-20.4 months (range, 6.0~87.4 months) after the last NR. Pre-NR mean IOP was 27.9+/-11.6 mm Hg and post-NR final IOP was 18.8+/-13.0 mm Hg (p=0.005). The success rate, defined as IOP < or =18 mm Hg with or without medication, was 80.3% (25 eyes of 31 eyes). The success rate was higher in the group receiving NR with adjunctive MMC (100%) than in the group receiving NR without MMC (62.5%) (p=0.018). Patients who underwent trabeculectomy without adjunctive MMC and those who had pre-NR IOP >25 mm Hg showed a higher failure rate, though with no statistical significance (p=0.141 and p=0.173, respectively). CONCLUSIONS: NR followed by subconjunctival injection of MMC is an effective and safe method for the treatment of the failed filtering blebs after trabeculectomy. Trabeculectomy without adjunctive MMC and pre-NR IOP higher than 25 mmHg were risk factors for failure of NR.
