PURPOSE: To determine the epidemiologic and clinical characteristics of thyroid-associated orbitopathy (TAO). METHODS: We retrospectively studied the clinical data of 385 patients from the New York City area diagnosed with TAO from January 1990 to December 2000. The total cases were divided into male and female groups and age-adjusted relative incidence rates were obtained to plot the incidence curve and clinical characteristics. Statistical analysis was applied to the collected data. RESULTS: The average age of patients with TAO was 46.3 years for females and 50.1 years for males. The female-male ratio was 5.31:1. In 23.3% of patients, the diagnosis of TAO was made simultaneously with their thyroid disease. In 75% of cases, the diagnosis was made within 18 months of the presentation of thyroid disease. Soft tissue involvement was noted most frequently in 311 (80.8%), eyelid retraction in 306 (79.5%), proptosis in 278 (72.2%), restrictive myopathy in 234 (60.8%), and compressive optic neuropathy in 43 (11.2%) of 385 patients. CONCLUSIONS: TAO has variable and different epidemiologic and clinical characteristics according to sex and age.

PURPOSE: To assess the relationships between optic cup-to-disc ratio (CDR) and age, sex, and other demographic and health characteristics in the healthy Korean population. METHODS: The study design was retrospective and population-based. A total of 28,377 subjects who participated in the Korea National Health and Nutrition Examination Survey between 2008 and 2011 were enrolled in this study. Participants underwent structured interviews as well as systemic and ophthalmic examinations. Patients with glaucoma who were diagnosed using the International Society of Geographical and Epidemiological Ophthalmology classification were excluded. Changes in vertical CDR were examined by age in relation to systemic variables on multiple regression analysis. RESULTS: The mean vertical CDR was 0.34 +/- 0.12. The vertical CDR increased with age from subjects in their 20s to those in their 80s (p < 0.001). The mean CDR in males was significantly higher than that of females (p < 0.001). On multiple regression analysis, the vertical CDR was positively associated with age (p < 0.001), male sex (p < 0.001), diastolic blood pressure (p = 0.009), and intraocular pressure (p < 0.001) but was negatively associated with body mass index (p < 0.001). CONCLUSIONS: Greater vertical CDR was related to age, male sex, higher diastolic blood pressure, higher intraocular pressure, and lower body mass index in healthy Koreans.

We investigated the ability of the GDx-Nerve Fiber Analyzer (NFA) to discriminate between normal and early glaucomatous eyes among Korean individuals by reviewing the medical records of 217 consecutive subjects: 61 early glaucoma patients, 68 ocular hypertensive patients, and 88 normal subjects. GDx parameters were compared using ANOVA. The Receiver Operating Characteristics (ROC) curve for each GDx-NFA variable was used to diagnose each parameter, and Pearson correlation coefficients were calculated to assess the association between GDx-NFA parameters and visual field indices in early glaucoma. The best GDx parameters to discriminate between early glaucomatous and normal subjects were the number, maximum modulation, ellipse modulation and inferior ratio (i.e. area under the ROC curve > 0.8). A value for the Number of equal to or greater than 27 was optimal for detecting early glaucoma, with a sensitivity of 80.3% and specificity of 80.7%. In addition, symmetry was positively correlated with the corrected pattern standard deviation (CPSD) among visual field indices in early glaucoma.
