Clinical Analysis of Findings for Anterior Segment Optical Coherent Tomography in Recurrent Corneal Erosion Syndrome

PURPOSE@#To evaluate the correlation between abnormal findings seen in anterior segment optical coherent tomography and the recurrence rate in patients with recurrent corneal erosion syndrome.@*METHODS@#Between January 2015 and August 2018, 53 eyes of 52 patients who had been diagnosed with recurrent corneal erosion syndrome were included in the study. Follow-up was performed for 12 months. To confirm the recurrence, we questioned the subjects on their symptoms and performed slit lamp examinations. At the first visit, the second week, and the first month, we performed anterior segment optical coherent tomography to identify pathologic findings for recurrent corneal erosion syndrome.@*RESULTS@#In 12 months, 29 eyes (54.7%) had a recurrence of corneal erosion and 24 eyes (45.3%) had no recurrence. There was no significant difference in age, sex, trauma, diabetes mellitus, or meibomian gland dysfunction between the recurrent and non-recurrent groups. Among the anterior segment optical coherent tomography findings, anterior stromal hyper-reflectivity, undetected epithelial basement membrane, intraepithelial basement membrane, intraepithelial inclusions were not significantly different between the two groups. In the first month, corneal epithelial edema was 82.8% in the recurrent group, but 33.3% in the non-recurrent group. It was significantly different (p = 0.000). Corneal epithelial thickness lowered significantly in the non-recurrent group, but not in the recurrent group in the first month. In other words, epithelial edema improved in the non-recurrent group, whereas epithelial edema did not improve in the recurrent group.@*CONCLUSIONS@#If corneal epithelial edema is not treated in patients with recurrent corneal erosion syndrome, high possibility of a recurrence should be considered.

Comparison of the Thickness and Volume of the Macula and Fovea in Patients with Anisometropic Amblyopia Prior to and after Occlusion Therapy

PURPOSE: To compare the thickness of superior, temporal, inferior, and nasal macula and foveal thickness and volume in patients with anisometropic amblyopia prior to and after successful occlusion therapy using optical coherence tomography (OCT) measurement. METHODS: Data were collected prospectively on 30 patients with unilateral anisometropic amblyopia from December 2006 to August 2007. All patients had anisometropia of 2.0 diopters or more. OCT scans were obtained for all patients at diagnosis. Occlusion therapy was then prescribed and OCT scans were obtained again at the time of successful occlusion therapy (defined as interocular difference of 0.05). However, mean foveal volume prior to occlusion therapy (0.15 ± 0.02 mm3) decreased after occlusion (0.14 ± 0.01 mm3) with statistical significance (Wilcoxon signed rank test, p = 0.025). CONCLUSIONS: There was a meaningful decrease in foveal volume in patients with anisometropic amblyopia after successful occlusion therapy. Whether this decrease relates to visual improvement of the amblyopic eye remains to be determined.

A Case of Acute Angle-closure Glaucoma Secondary to Spontaneous Suprachoroidal Hemorrhage

PURPOSE: To report a case of acute angle-closure glaucoma secondary to spontaneous suprachoroidal hemorrhage in a hemodialysis patient. CASE SUMMARY: A 71-year-old man visited our clinic after 3 days of vision loss and ocular pain in the right eye. He had been treated with hemodialysis using heparin due to diabetic nephropathy. Visual acuity (VA) was hand motion in the right eye and 0.2 in the left eye. The intraocular pressure (IOP) was 58 mmHg in the right eye and 15 mmHg in the left eye. Gonioscopic examination revealed a closed angle in the right eye. Fundus examination of the right eye showed a massive hemorrhagic retinal detachment and ultrasound sonography revealed a dome-shaped retinal detachment with suprachoroidal hemorrhage in the right eye. The patient was treated with topical aqueous suppressants and cycloplegics. After two weeks of medical treatment, VA in the right eye was still hand motion and IOP was 8 mmHg. Gonioscopic examination showed a wide-open angle in the right eye. During the two-month observation period, VA in the right eye did not recover, however there was no sign of IOP elevation or symptoms of ocular pain. CONCLUSIONS: Spontaneous suprachoroidal hemorrhage can occur in patients who receive hemodialysis with heparin. This spontaneous suprachoroidal hemorrhage can be subsequently accompanied by acute angle-closure glaucoma. Spontaneous decrease of suprachoroidal hemorrhage, loss of angle-closure, and decline of IOP can be expected by treating with topical aqueous suppressants and cycloplegics.

Metastatic Tumor of Tunica Vaginalis Testis with Hydrocele in a Patient with Gastric Cancer / 대한비뇨기과학회지

Metastatic tumors of the tunica vaginalis testis from gastric cancer are extremely rare. We report here on a case of a 48-year-old man who had undergone total gastrectomy due to advanced gastric cancer 23 months previously, and he presented with right painless scrotal swelling. A hard mass was palpated along the right spermatic cord and there was an associated hydrocele around the mass. Ultrasonography showed homegenous hypoechoic lesions in the spermatic cord and anechoic lesion superior to the right testis, which was suggestive of hydrocele of the testis. Exploration was performed via inguinal incision. Multiple hemorrhagic small nodules were noted on the surface of the tunica vaginalis. Also, a tumor in the spermatic cord was present beyond the inner inguinal ring. On microscopic examination, adenocarcinoma cell nests, which were consistent with primary gastric cancer, were found in the tunica vaginalis testis, spermatic cord and peritesticular soft tissue, but not within the parenchyme of the testis or epididymis.

Long Term Follow-up Results of Extraperitoneal Laparoscopic Burch Bladder Neck Suspension / 대한비뇨기과학회지

PURPOSE: Despite the encouraging short-term results after the laparoscopic Burch operation for female stress urinary incontinence, many investigators reported the decreases of the success rate on long-term follow up studies. These facts have urged us to investigate the change of success rate on long term follow up and related factors of them. MATERIALS AND METHODS: This study was performed for 39 patients who have received laparoscopic Burch operation from May 1995 to December 1996. Mean follow up duration was 41 months (32-50 months). Extraperitoneal approach was performed in all cases, and postoperative 3 months and long term follow-up results were assessed using standardized questionnaire and medical record. Symptom grades were categorized by Stamey grade. Factors affecting postoperative outcome and complications were also analyzed. RESULTS: On 3 month short term follow-up, 64.1% were cured and 28.2% were improved. However, on the long term follow-up, success rates were droped to 46.1% and 25.6% respectively. Factors affecting postoperative outcome were preoperative Stamey grade and VLPP. Age, parity, symptom's duration, body weight had no correlation with post-operative results. Of the 12 patients with preoperative symptoms of urgency and/or urge incontinence, 8 patients reported those were disappeared or decreased postoperatively. Obstructive symptoms occurred in 7 cases, but progressively improved with time. CONCLUSIONS: With these results, we could conclude that initial success rate of laparoscopic Burch operation is high, but it declined with time. However, on the basis of the result that Stamey grade I patient had lower failure rate, we could selectively apply this operation for grade I stress urinary incontinence.

Congenital Bladder Diverticulum Misdiagnosed as Non-neurogenic Neurogenic Bladder / 대한비뇨기과학회지

Congenital bladder diverticulum usually occurs in areas where the muscle is inadequately formed, typically at the ureterovesical junction, or between bundles of hypertrophied muscle. Congenital bladder diverticulum might be missed in excretory urography, especially in case that primary symptom is not so severe to justify further invasive studies. Physicians should not neglect voiding symptoms in pediatric patients and should have high suspicion of congenital diseases. We report a case of rare congenital bladder diverticulum, misdiagosed as non-neurogenic neurogenic bladder, presenting as nocturnal enuresis, daytime frequency and post-voiding residual urine sensation without vesicoureteral reflux or outlet obstruction.
