PURPOSE: To assess the relationship between the internal diameter of the nasolacrimal duct and the success rate of silicone tube intubation in incomplete nasolacrimal duct obstruction patients with epiphora. METHODS: Dacryocystography was performed 80 patients with symptoms of epiphora and the anteroposterior (AP) diameters and the lateral diameters of the nasolacrimal ducts were measured. These measurements were compared between the group of patients who demonstrated improvement after the operation, and the group without symptom improvement. RESULTS: The mean length of the nasolacrimal duct in the group with nasolacrimal stenosis was 11.7+/-0.1 mm, the mean lateral diameter was 1.0+/-0.2 mm, and the mean AP diameter was 1.1+/-0.1 mm. The AP diameter of the symptomatic nasolacrimal duct in the group with successful postoperative results was 1.1+/-0.1 mm, and 0.9+/-0.1 mm in the group with unsuccessful results. The group with successful postoperative results had an average of 18.1+/-7.0% stenosis in the side of the eye with nasolacrimal duct stenosis compared with the asymptomatic side, and the group with unsuccessful postoperative results had an average of 34%+/-3.6% stenosis. CONCLUSIONS: In cases with nasolacrimal duct stenosis, the success rate of silicone tube intubation was high when the AP diameter of the nasolacrimal duct was more than 1.1+/-0.1 mm and when the stenosis was less than 18.1+/-7.0% in the symptomatic side compared with the opposite side. These results are expected to help predict the success rates when preoperatively planning silicone tube intubation.

PURPOSE: The purpose of this study was to measure knowledge, attitude, experience of sex, sexual autonomy and the need of sex education of college students in order to provide sex information. METHOD: The subjects of this study were 356 college students. The data were collected from October 26 to December 5, 2003 by using a structured questionnaire. RESULT: The respondents' score of sexual knowledge was relatively low as 53.7 mean score on the basis of 100. However, the scores of sexual knowledge related to masturbation, induced abortion, and contraception were relatively high. The respondents' score of sexual attitude was 3.09. The respondents' score of sexual autonomy was 3.89. The percentage of subjects that experienced sexual intercourse was 41.6% and there was a difference between the gender. There was a positive correlation between sexual knowledge and sexual autonomy and between sexual knowledge and sexual attitude. There were significant differences in the sexual knowledge, sexual attitude and sexual autonomy depending upon the experience of coitus. The respondents expressed the need of sex education in college. CONCLUSION: An integrated sex education program should be developed and contents must have a concrete and honest education which is appropriate to college students.

Central serous chorioretinopathy(CSC) is characterized by a serous elevation of neurosensory retina in the posterior pole of the fundus. Its etiology and pathophysiological basis are still unknown. But it is known to be related to corticosteroid therapy. We experienced a development of CSC in a patient who had taken high dose systemic corticosteroid to treat sudden hearing loss. So we report this case with a review of the literatures.

PURPOSE: To analyze the clinical features of orbital wall fracture with diplopia between the surgical treatment group and the conservative treatment group. METHODS: The study comprised of 109 eyes of 109 patients with orbital wall fracture and diplopia. The patients were divided into two groups: the surgical treatment group (59 cases) and the conservative treatment group (50 cases). The groups were analyzed retrospectively according to age, gender, cause, CT, the period and severity of diplopia, and enophthalmos with time. RESULTS: In the conservative treatment group, 38 cases (64.4%) had medial wall fracture, and the average fracture size was 26alpha of the inferior wall and 33% of the medial wall. In addition, at the first visit, the patients showed diplopia within 45.5 degrees, and diplopia disappeared completely within 17 days on average (57 cases, 96.6%). In the group that underwent the reconstruction of orbital wall fracture, 27 cases (54.0%) had inferior wall fracture, and the average fracture size was 41% of the inferior wall and 35% of the medial wall. Additionally, in the first visit, the patients showed diplopia within 20.3 degrees. The muscle incarceration occurred in 12 cases (24%). In the surgical treatment group, diplopia disappeared completely within 30 days on average (45 cases, 90.0%). CONCLUSION: In the group of conservative treatment, they showed diplopia within 45.5 degrees at the first visit. Diplopia disappeared completely within 17 days on average (57 cases, 96.6%). In the group of surgical treatment, they showed diplopia within 20.3 degrees at the first visit. Diplopia disappeared completely within 30 days on average (45 cases, 90.0%).

PURPOSE: A comparison analysis of the clinical characteristics and treatment results of congenital NLD obstruction. METHODS: The present study involved 216 pediatric patients (258 eyes) diagnosed with and treated for congenital NLD obstruction. Treatment was applied step by step starting with conservative massaging, lacrimal probing, and silicone tube intubation. RESULTS: The treatment results of congenital NLD obstruction in pediatric patients under 12 months of age showed an 87.3% success rate after an average of 4.3 months of treatment in the group using lacrimal sac massage and antibiotic eye drops (conservative treatment). The group treated by correct massaging techniques showed a 93.6% success rate after an average of 3.8 months of treatment. The success rate of lacrimal probing, applied to patients not showing improvement after massage therapy was 77.8%. Pediatric patients not showing improvement after lacrimal probing underwent silicone tube intubation. All patients showed improvement except in 1 case that had an early silicone tube dislocation. DISCUSSION: A step-by-step approach is effective in treating congenital NLD obstruction patients, and correct lacrimal massage techniques improve the success rate during conservative therapy. The period of conservative treatment and number of probing times did not have a statistically significant correlation with the success rate of lacrimal silicone tube intubation. Silicone tube intubation showed a high success rate in patients sustaining the silicone tube for a minimum of 2.1 months.

PURPOSE: This study evaluated the relationship of nasal cavity state and surgical results after endonasal dacryocystorhinostomy (DCR). METHODS: We retrospectively analyzed 306 eyes of 204 patients between January 2007 and December 2011. The correlation between the existence of preoperative nasal cavity abnormality, postoperative nasal cavity complications after proper management of nasal cavity abnormality, and postoperative nasal cavity complications according to nasal packing material were investigated. We analyzed the success rates and the correlation between each set of factors. RESULTS: The success rate of primary operations performed six months after tube removal was 87.3% (267/306). The success rate after secondary revision, granuloma removal and punctoplasty was 90.5% (277/306). Postoperative nasal cavity complications were inspected in 40 eyes. Of the 306 eyes, patients treated with Nasopore showed significantly more postoperative nasal cavity complications (47.8%, 32/67) than in patients treated with Merocel (3.3%, 8/239). The rate of postoperative nasal cavity complications was 8.7% in patients with normal nasal cavity, 16.7% in patients who received treatment, and 20% in patients without treatment, with significant statistical increase if the nasal cavity was abnormal (p = 0.019). The incidence of complications influenced the primary success rate (p = 0.008); however, preoperative nasal cavity abnormalities were not correlated with primary success (p = 0.479). CONCLUSIONS: In the case of endonasal DCR, preoperative nasal cavity abnormality and type of nasal packing material used did not affect the success rate but significantly affected postoperative nasal cavity complications. In conclusion, endonasal DCR with preoperative treatment of nasal cavity abnormality and Merocel packing is expected to reduce postoperative nasal cavity complications and increase patient satisfaction.

PURPOSE: To report a case of multiple endocrine neoplasia type 2B (MEN 2B) diagnosed early based on conjunctival neuroma. CASE SUMMARY: A 15-year-old female presented with red eye and conjunctival mass in both eyes. A 5 x 5 mm-sized yellowish conjunctival mass adjacent to the limbus was observed in her right eye and a 3 x 3 mm-sized mass in her left eye. Excisional biopsy was performed and the patient was diagnosed with conjunctival neuroma. Other abnormalities were not found on the ophthalmic examination, but she had characteristic appearances such as thickened upper eyelid, mild telecanthus and nodular edematous upper lip. She was transferred to the Endocrinology Department for systemic evaluation in consideration of multiple endocrine neoplasia. Abdominal pelvic computed tomography and a 24-hr urine collection analysis showed asymptomatic pheochromocytoma. Thyroid ultrasonography and fine-needle biopsy revealed medullary thyroid carcinoma. Finally, MEN type 2B was confirmed by using a RET mutation gene test. CONCLUSIONS: Thyroid carcinoma can occur in MEN 2B in combination with pheochromocytoma and mucosal neuroma. Thickened corneal nerve fiber and perilimbal conjunctival mass have been regarded as ophthalmologic characteristics of MEN 2B and may be accompanied by telecanthus, thickened upper eyelid and marfanoid habitus. A biopsy of the mass is required for pathological diagnosis. Medullary thyroid carcinoma is the most significant clinical component of MEN 2B syndrome and thyroidectomy is indicated. MEN 2B may be a rare syndrome, but its consequences are serious and the ophthalmologist may play a lifesaving role in its diagnosis.

PURPOSE: We used computed tomography (CT) scans to describe normal Korean lacrimal gland volume and lacrimal gland size and then examined their correlations with patient age. METHODS: CT scans were obtained in 213 orbits of 111 patients who underwent CT from January to August of 2013. Aquarius iNtuition (TeraRecon, Foster City, CA, USA) software was used to outline the lacrimal gland in consecutive axial slices and to calculate the volume. RESULTS: The mean volume of the lacrimal gland was 0.589 cm3 in right orbits (SD = 0.090), 0.583 cm3 in left orbits (SD = 0.289), 0.596 cm3 in males (SD = 0.083), and 0.575 cm3 in females (SD = 0.094). There was no significant difference in mean lacrimal gland volume according to laterality (p = 0.614) or sex (p = 0.102) (2-sample t-tests). We investigated mean lacrimal gland volume in 3 age groups. Mean lacrimal gland volume was 0.630 cm3 (SD = 0.080) for the 20 to 40 year old group, 0.553 cm3 (SD = 0.734) for the 41 to 60 year old group, and 0.544 cm3 (SD = 0.885) for the older than 60 years old group. There was an inverse relationship between gland volume and age (Pearson r = -0.384, p = 0.00). CONCLUSIONS: The mean volume of the lacrimal gland decreased with age and there was no significant difference between right and left orbits or between male and female patients.
