Purpose: To investigate optic disc morphology in high axial myopia and its associations with the deep-layer structure of the optic disc using optical coherence tomography and glaucoma. Methods: We retrospectively reviewed the medical records of 69 eyes (33 normal and 36 glaucomatous eyes) with an axial length of 26-27 mm. The eyes were categorized into two groups based on the optic disc tilt ratio (≥ 1.3 or < 1.3). Characteristics of optic disc morphology, including lamina cribrosa depth, peripapillary atrophy width, and Bruch’s membrane opening area, were compared between the two groups. Furthermore, factors related to mean deviation and global retinal nerve fiber layer (RNFL) thickness were analyzed. Results: The mean optic disc tilt ratio was 1.31 ± 0.23. Eyes with a tilt ratio ≥ 1.3 (30 eyes) had a higher likelihood of glaucoma (p = 0.035) and severe visual field (VF) defects (p < 0.001), a thinner global RNFL thickness (p = 0.046), and larger gamma peripapillary atrophy width (p < 0.001) compared to eyes with a tilt ratio < 1.3 (39 eyes). Linear regression analysis revealed that the optic disc tilt ratio was significantly associated with VF loss (p = 0.018) but not with global RNFL thinning (p = 0.203). Conclusions Variations in optic disc morphology are observed in eyes with similar axial lengths, and a higher optic disc tilt ratio is associated with more severe VF defects. These findings suggest the potential influence of optic disc morphological changes due to axial elongation on the severity of glaucomatous damage.

Purpose: Pediatric diabetes is a common health burden worldwide. This study aimed to investigate the prevalence of fasting hyperglycemia in Korean youth aged 10–18 years and to evaluate its association with metabolic indicators. Methods: To assess the risk of diabetes in domestic children and adolescents, the prevalence of fasting hyperglycemia was calculated, a trend was evaluated using multi-year Korea National Health and Nutrition Examination Survey (KNHANES) data, and multivariate analysis was performed to evaluate the relationships between hyperglycemia and metabolic factors. Results: The prevalence of fasting hyperglycemia, defined as impaired fasting glucose (fasting glucose level > 100 mg/dL and < 125 mg/dL), or diabetes mellitus (fasting glucose ≥ 126 mg/dL) was estimated in Korean teenagers. The prevalence increased from the fourth (2007–2009) to the fifth (2010–2012), sixth (2013–2015), and seventh (2016–2018) KNHANES surveys, from 5.39 to 4.79, 10.03, and 11.66 per 100 persons, respectively. In multivariate analysis, systolic blood pressure and serum triglycerides were higher in the fasting hyperglycemia group; systolic blood pressures were 109.83 mmHg and 112.64 mmHg and serum triglycerides were 81.59 mg/dL and 89.60 mg/dL in the normal blood glucose and fasting hyperglycemia groups, respectively. Conclusion The prevalence of fasting hyperglycemia among children and adolescents has increased over the past decade, and this increase is potentially associated with metabolic abnormalities such as hypertension and hypertriglyceridemia. Effort is urgently required to reduce this chronic medical burden in adolescence.

BACKGROUND/AIMS: Primary thyroid disease is prevalent in chronic renal disease, especially in patients requiring chronic dialysis. However, the relationship between kidney function and the prevalence of primary thyroid disease has not been studied in Korea, a nation where the dietary iodine intake is excessive. METHODS: Retrospective data from 2201 consecutive adult patients who visited a health promotion center over the last 5 years were analyzed; specifically, 54 patients with chronic kidney disease not requiring hemodialysis and 64 adults treated with hemodialysis. The glomerular filtration rate (GFR) was estimated using the abbreviated Modification of Diet in Renal Disease equation. Multivariable logistic regression was used to evaluate the independent association between the prevalence of primary hypothyroidism and estimated GFR. RESULTS: The prevalence of overt hypothyroidism increased from 0.5% at an estimated GFR > 90 mL/min/1.73 m2 to 6.3% in end-stage renal disease requiring chronic dialysis (p < 0.001 for trend). Compared with participants with an estimated GFR > 60 mL/min/1.73 m2, those with an estimated GFR < 60 mL/min per 1.73 m2 had an increased odds of overt hypothyroidism after adjusting for age, gender, fasting blood glucose (FBS), and the total cholesterol (TC) and triglyceride (TG) concentrations. CONCLUSIONS: These findings suggest that overt primary hypothyroidism is relatively common (6.3%) among persons with chronic kidney disease requiring chronic dialysis, and it is independently associated with a progressively lower estimated GFR.

PURPOSE: To investigate the retinal nerve fiber layer (RNFL) thickness concordance when measured by spectral domain (SD) and swept source (SS) optical coherence tomography (OCT), and to compare glaucoma-discriminating capability. METHODS: RNFL thicknesses were measured with the scan circle, centered on the optic nerve head, in 55 healthy, 41 glaucoma suspected, and 87 glaucomatous eyes. The RNFL thickness measured by the SD-OCT (sdRNFL thickness) and SS-OCT (ssRNFL thickness) were compared using the t-test. Bland-Altman analysis was performed to examine their agreement. We compared areas under the receiver operating characteristics curve and examined sdRNFL and ssRNFL thickness for discriminating glaucomatous eyes from healthy eyes, and from glaucoma suspect eyes. RESULTS: The average ssRNFL thickness was significantly greater than sdRNFL thickness in healthy (110.0 ± 7.9 vs. 100.1 ± 6.8 µm, p < 0.001), glaucoma suspect (96.8 ± 9.3 vs. 89.6 ± 7.9 µm, p < 0.001), and glaucomatous eyes (74.3 ± 14.2 vs. 69.1 ± 12.4 µm, p = 0.011). Bland-Altman analysis showed that there was a tendency for the difference between ssRNFL and sdRNFL to increase in eyes with thicker RNFL. The area under the curves of the average sdRNFL and ssRNFL thickness for discriminating glaucomatous eyes from healthy eyes (0.984 vs. 0.986, p = 0.491) and glaucoma suspect eyes (0.936 vs. 0.918, p = 0.132) were comparable. CONCLUSIONS: There was a tendency for ssRNFL thickness to increase, compared with sdRNFL thickness, in eyes with thicker RNFL. The ssRNFL thickness had comparable diagnostic capability compared with sdRNFL thickness for discriminating glaucomatous eyes from healthy eyes and glaucoma suspect eyes.

PURPOSE: To report the choroidal neovascularization of 4 patients in central serous chorioretinopathy treated with laser treatment. CASE SUMMARY: We reported 4 patients with central serous chorioretinopathy. Three patients were treated with focal laser photocoagulation, and 1 patient with photodynamic treatment. All patients newly developed choroidal neovascularization (CNV) after treatment at the area of laser treatment. Three patients received intravitreal anti-VEGF injection and 1 patient received argon laser photocoagulation for the treatment of CNV. After the treatment, the CNV was resolved with improved visual acuity. CONCLUSIONS: Laser treatment may be efficacious tool to achieve rapid resolution in central serous chorioretinopathy until now. However, more caution at the time of treatment and close follow-up after treatment are warranted.
