We report a case of complicated cataract aggravated after taking herbal medication for atopic dermatitis. An 11-yr-old boy was referred for the evaluation of decreased visual acuity in both eyes for 2 months. Past history showed that he had been diagnosed with atopic dermatitis when he was 1 yr old. He had been treated only with herbal medication for a period of 8 months prior to visiting our clinic. He had his visual acuity checked in a local ophthalmic clinic one year before, and the visual acuity was 20/20 in both eyes at that time. When attending our clinic the ophthalmologic examination showed that his best corrected visual acuity was 20/200 in both eyes. Lenses of both eyes had severe posterior subcapsular and posterior capsular opacity. Phacoemulsification, posterior chamber intraocular lens implantation, and posterior continuous curvilinear capsulectomy were performed in both eyes. After 3 months postoperatively, the best corrected visual acuity was recovered to 20/20 in both eyes without any complication. Our case suggests that there may be a risk of aggravation of cataract or development of cataract after treatment with some unidentified herbal medication in a patient with atopic dermatitis.

PURPOSE: To find the optimal parameter of retinal nerve fiber layer (RNFL) analysis using optical coherence tomography (OCT) and to compare the diagnostic precision between the new discriminant formula and the preprogrammed indicator (95%, 99% cut off value of normal RNFL thickness) in the diagnosis of glaucoma. METHODS: The study comprised 499 eyes of 284 patients. Routine ophthalmic examinations, fundus examination, visual field test, OCT optic nerve head analysis and OCT RNFL analysis were performed. Results were analyzed and classified into normal, suspected glaucoma, and glaucoma groups. RESULTS: There were 237 glaucomatous eyes and all parameters of the OCT RNFL analysis showed statistically significant differences between the glaucoma and non-glaucoma groups. The average RNFL thickness was most significantly correlated with the visual field indexes and was the most useful parameter in the detection of glaucoma. Using age, horizontal integrated rim area (HIRA) and average thickness, the accuracy, sensitivity and specificity of the new discriminant formula were 76.2%, 73.1% and 73.1% respectively. CONCLUSIONS: Average thickness was the most useful parameter in the detection of glaucoma. The next most useful parameter was inferior average thickness, and both were more precise than the preprogrammed indicator. The new discriminant formula is useful in the diagnosis and follow-up of the glaucoma patients.

Purpose: To compare the visual and anatomical outcomes of intravitreal bevacizumab combined with the dexamethasone intravitreal implant (Ozurdex®) and bevacizumab monotherapy in eyes with treatment-naive diabetic macular edema. Methods: We retrospectively reviewed 41 eyes of 41 patients with diabetic macular edema who underwent either intravitreal bevacizumab (1.25 mg) (21 eyes, intravitreal bevacizumab [IVB] group) injection alone or simultaneous injection of bevacizumab (1.25 mg) and dexamethasone implant (0.7 mg) (20 eyes, intravitreal dexamethasone [IVD] group). Best-corrected visual acuity (BCVA), central macular thickness (CMT), intraocular pressure, and retreatment percentages were accessed 1, 3, and 6 months after injection. Results: At 3 and 6 months, the IVD group showed a significant improvement in BCVA compared to the baseline. Only a slight improvement in BCVA was observed in the IVB group during the initial 3 months; however, significant improvement was evident at 6 months compared with the baseline. During the first 3 months, the IVD group showed significant improvement in CMT compared with the IVB group; at 1 month after the initial injection, the CMT was 264.39 ± 54.95 μm for the IVD group versus 349.00 ± 112.18 μm for the IVB group (p = 0.011). At 3 months, the CMT in the IVD group had improved significantly compared with that of the IVB group (p < 0.001). The average number of additional intravitreal injections during the 6-month follow-up was 0.45 and 1.15 for the IVD and IVB groups, respectively. In the IVD group, cortical (7%) and posterior subcapsular (15%) cataracts developed by two grades or more during follow-up in phakic eyes. Conclusions In patients with diabetic macular edema, simultaneous therapy combining a dexamethasone implant plus bevacizumab showed significant improvement in CMT during the initial 3 months and the combined treatment group had fewer additional intravitreal injections.

Purpose: To analyze the therapeutic effects, prognostic factors, and complications that occurred after iStent® or iStent inject® implantation in South Korean glaucoma patients. Methods: We retrospectively analyzed 42 eyes of South Korean glaucoma patients, who were followed-up for more than 6 months after iStent® or iStent inject® implantation alone or combined with cataract surgery. Surgical success was defined as an intraocular pressure (IOP) ≤21 mmHg and an IOP reduction ≥20% from preoperative IOP levels. Results: The cumulative success rate at 6 months after surgery was 45.3 ± 8.1% for iStent inject® alone (group A), 28.6 ± 13.1% for iStent® alone (group B), 81.2 ± 6.8% for iStent inject® combined with cataract surgery (group A-1), and 27.3 ± 21.8% for iStent® combined with cataract surgery (group B-1). Group A-1 showed a higher success rate than group B-1 (p = 0.007); the difference in success rates between groups A and B was not statistically significant (p = 0.579). When the success prognostic factors were analyzed by Cox regression analysis, the results showed that a higher preoperative IOP was associated with a higher surgical success rate (hazard ratio 0.80, p = 0.02). Conclusions In our patient group, iStent inject® was more effective than iStent® in combination with cataract surgery. The higher the preoperative IOP, the higher the surgical success rate; the results were significant.

PURPOSE: To investigate the causes and characteristics of glaucoma in children following cataract surgery. METHODS: Twenty-four patients (37 eyes) with uncomplicated congenital cataracts who developed glaucoma after cataract surgery were studied retrospectively. Variables included cataract morphology, surgical techniques, post-operative complications, time to the onset of glaucoma, gonioscopic findings, presence of microcornea and the histopathologic characteristics of the filtration angle (in one case). RESULTS: There was a bimodal onset of glaucoma after cataract surgery. Early-onset glaucoma occurred at a mean age of 6 months in 15 eyes and delayed-onset glaucoma at a mean age of 12 years in 22 eyes. Early-onset glaucoma was significantly (p=0.018) more likely to be due to angle closure than delayed-onset glaucoma. With delayed-onset glaucoma, the filtration angle was open in 86% of eyes and significantly (p=0.006) more eyes in the delayed-onset group had microcornea. Medical treatment was sufficient to control intraocular pressure in the delayed-onset group while the early-onset group required surgical treatment (P<0.001). CONCLUSIONS: The onset of glaucoma after cataract surgery during infancy follows a bimodal pattern that is correlated with the configuration of the filtration angle. The early-onset glaucoma group had high incidence of angle closure requiring surgical treatment, while in the delayed-onset group non-surgical treatment was sufficient to control intraocular pressure. Prophylactic iridectomy in eyes at risk for pupillary block is recommended. Eyes with delayed-onset glaucoma have open filtration angles yet also have findings of incomplete development of filtration structures. Microcornea is a risk factor for delayed-onset glaucoma.

PURPOSE: To report a case of bleb dysesthesia successfully treated after Baerveldt tube implantation. CASE SUMMARY: A 37-year-old woman presented with a history of persistent foreign body sensation and pain in the left eye. The patient was referred to our hospital and was diagnosed as having had plateau iris syndrome. Having shown no improvement with conservative management, she eventually received trabeculectomy in the left eye six months prior to her current presentation. Under the impression of bleb dysesthesia, she received artificial tears and a bandage contact lens. These, however, failed to alleviate her symptoms. She then had a compression suture of the bleb and bleb revision. These were performed sequentially but neither was effective. Finally, a Baerveldt tube implantation was performed successfully, and, three months later, bleb revision was performed using a donor sclera, which resulted in no further complaint of ocular discomfort. CONCLUSIONS: Bleb dysesthesia, although not a common postoperative complication, can occur after trabeculectomy and can be successfully treated with Baerveldt tube implantation. Patients should receive appropriate counseling and advice on bleb dysesthesia prior to undergoing trabeculectomy.

PURPOSE: To find the optimal parameter of retinal nerve fiber layer (RNFL) analysis in optical coherence tomography (OCT) for diagnosing glaucoma in children. METHODS: The study was comprised of 127 eyes of 84 patients (aged 6 to 18 years) who visited our institute between March 2006 and February 2008. Subjects were classified into normal, glaucoma suspect and glaucoma groups, and each eye was scanned using Stratus 3.0 OCT. Routine ophthalmic examinations including fundus examination, visual field test and OCT RNFL analysis were performed. RESULTS: There were 55 normal eyes, 27 glaucoma suspect eyes and 45 glaucomatous eyes. The average RNFL thickness was the most useful parameter to differentiate between the glaucoma and non-glaucoma groups. The next most useful parameter was inferior average thickness, followed by superior RNFL thickness. The sensitivity and specificity of the new discriminant of the formula used were 78%, and 68.6%, respectively. CONCLUSIONS: In OCT analysis, the average RNFL thickness is the most useful parameter in the diagnosis of glaucoma in children. The new discriminant of the formula is useful in the diagnosis of pediatric glaucoma patients.

This study was conducted to find out the risk factors of hypertension and the effect of thesefactors on blood pressure. The eighteen factors were collected on the subjects of 932 from November 1994 to January 1995 through questionnaire and laboratory test - those were age, sex, education level, body mass index(BMI), family history of hypertension (FHH), triglyceride (TG), blood sugar and lactate dehydrogenase(LDH), etc. The status of blood pressure was classified by the classification of hypertension proposed by Joint National Committee of hypertension, USA. The prevalence of diastolic hypertension was 17.7% and the prevalence of systolic hypertension was 11.6 %. In the frequency analysis on the status of blood pressure, by age, education level, smoking habit, RM, BMI, FBS, LDH, TG, the prevalences were significantly different for both diastolic and systolic hypertension(p(0. 05). By stepwise logistic regression with dichotemization of blood pressure, the following odds ratios were significantly high (p, 0.05) - for diastolic hypertension, age 1.973, BMI 2. 106, FHH 2, 102, LDH 2. 773, TG 1.715, and for systolic hypertension, age 4.414, BMI 1.563, FHH 2.125, RM 0.487, LDH 3.814, TG 2. 707. By multiple regression analysis with blood pressure as dependent variable and these factors as independent variables, the regression equationswere diastolic hypertension =51.07+0.20.age+0.07 BMI+0.02.TG+0.02.LDH+3.22.FHH, and systolic hypertension = 88. 59+0.23.age+0.06.BMI+5.46.FHH-2.62.RM+0.03.LDH+0,03.TG By this study, the significant risk factors of hypertension were age, BMI, TG, family history of hypertension, LDH, and efficient control of hypertension would be expected through control of these factors.
