Résumé
Purpose@#To evaluate the usefulness of a newly generated monofocal intraocular lens (IOL) in patients with various retinal diseases who underwent combined cataract and pars plana vitrectomy surgery. @*Methods@#This prospective observational study included 33 patients with various retinal diseases. Monocular best-corrected distance visual acuity (BCDVA), uncorrected distance visual acuity (UCDVA), uncorrected intermediate visual acuity (UCIVA), uncorrected near visual acuity (UCNVA), and contrast sensitivity were measured and compared with 40 age-matched patients in the standard monofocal IOL. @*Results@#The Eyhance IOL group demonstrated significantly better UCIVA at 6 months follow-up compared to the standard monofocal IOL group. No significant differences were observed between the two groups in contrast sensitivity, BCDVA, UCDVA, or UCNVA. The regression analysis showed a significant association between preoperative corrected distance visual acuity and improved UCIVA in the Eyhance IOL group. @*Conclusions@#The Eyhance ICB00 IOL proved to be a valuable option for patients with retinal diseases undergoing combined cataract surgery and vitrectomy. It effectively improved intermediate vision without compromising contrast sensitivity or distance visual acuity.
Résumé
Background@#Uveitis is less common in children than in adults; however, pediatric uveitis has a relatively severe disease course that affects the quality of life. Although it is important to understand the epidemiological characteristics of pediatric uveitis, few studies have been conducted in large populations without referral bias. This study investigated the nationwide incidence and prevalence of pediatric uveitis in South Korea according to period, age, anatomic type, and systemic associations. @*Methods@#This nationwide population-based cohort study used data from the Korean National Health Insurance Service from 2002 to 2018. This study included patients younger than 19 years of age with noninfectious uveitis with at least three claims of diagnostic codes of uveitis on separate days with at least once claim of prescription codes of steroid and immunosuppressive agents. All the cases were classified as anterior or non-anterior uveitis, and the overall incidence and prevalence were estimated by age, sex, and period. Patients with noninfectious uveitis were categorized by the presence of associated systemic conditions. @*Results@#A total of 10,862,616 patients over 128,688,078 person-years were evaluated from 2005 to 2016. Overall, 5,368 cases of anterior uveitis and 604 cases of non-anterior uveitis were identified. The incidence and prevalence of pediatric noninfectious uveitis were 4.64 per 100,000 person-years (95% confidence interval [CI], 4.52–4.76) and 8.25 per 100,000 persons (95% CI, 8.09–8.41). Both the incidence and prevalence of pediatric uveitis increased with age. Anterior uveitis accounted for 84.7% of pediatric noninfectious uveitis prevalent cases (6.99 per 100,000 persons). Cases of juvenile idiopathic arthritis (JIA)-associated uveitis accounted for 8.7% (926 cases) of pediatric noninfectious uveitis cases with a prevalence of 0.72 per 100,000 (95% CI, 0.67–0.77). The proportion of systemic associations was higher and JIA-related uveitis accounted for 11.2% (803 cases) of recurrent or chronic noninfectious uveitis cases with a prevalence of 0.62 per 100,000. @*Conclusion@#This is the first population-based study investigating the largest population of pediatric patients with uveitis in Korea. The nationwide incidence and prevalence of pediatric noninfectious uveitis in 2005–2016 were 4.64 per 100,000 person-years and 8.25 per 100,000, respectively. The proportion of JIA in pediatric noninfectious uveitis was 8.7%.These population-based study findings provide a better understanding of the public health burden and aid in the planning of health-care strategies for pediatric patients with uveitis.

50 years) showed lower MPOD than younger (30–49 years) subjects. But, in the healthy population, the estimated MPOD values exhibited a decreasing trend with age, but there were no significant differences according to age, after excluding patients with AMD. MPOD was significantly lower in patients with AMD than in aged healthy controls. Furthermore, hypertension, dyslipidemia, and smoking were identified as risk factors for AMD.CONCLUSION: MPOD measured with MPSII® reflects the MP density in healthy individuals and patients with dry AMD. Aging was not significantly associated with low MPOD in healthy population, but the presence of dry AMD was significantly associated with low MPOD. Then, low MPOD may be a risk factor for development of dry AMD. Furthermore, routine screening with MPS II® for ages 50 and older is thought to help detect early low MPOD and identify individuals who should take supplements.

BACKGROUND@#To evaluate the macular pigment optical density (MPOD) with age in the Korean population using the Macular Pigment Screener II (MPSII®).@*METHODS@#One hundred and twenty-six eyes were retrospectively reviewed. MPOD was measured using MPSII®, which uses a heterochromatic flicker photometry method, and the estimated values were analyzed. Spearman's correlation test was used to evaluate correlations between MPOD and age. The association between MPOD and age was determined using a simple linear regression analysis. MPODs among the four groups were compared via the post hoc analysis with Bonferroni correction, MPODs between the age-related macular degeneration (AMD) group and aged-matched healthy subjects were compared via the Mann-Whitney U test. Other risk factors for AMD were identified via a logistic regression analysis.@*RESULTS@#Estimated MPOD decreased significantly with increasing age in the general population. In the simple regression analysis, a statistically significant linear regression model was observed, and the estimated values of MPOD decreased by −0.005 as age increased by 1 year. Aged (> 50 years) showed lower MPOD than younger (30–49 years) subjects. But, in the healthy population, the estimated MPOD values exhibited a decreasing trend with age, but there were no significant differences according to age, after excluding patients with AMD. MPOD was significantly lower in patients with AMD than in aged healthy controls.

PURPOSE: To compare the central corneal thickness (CCT) in eyes of Korean subjects with primary angle-closure glaucoma (PACG) to other patients with glaucoma and control subjects. METHODS: Medical records of patients who underwent examination for glaucoma and pre-operative examination for cataract surgery between March 2009 and August 2012 in our clinic were reviewed. CCT was compared in normal control eyes, primary open angle glaucoma (POAG) eyes and normal tension glaucoma (NTG) eyes. RESULTS: The mean CCT of POAG eyes was significantly larger than that of normal control eyes, NTG eyes and PACG eyes (p = 0.027, 0.009 and 0.008, respectively). There was no significant difference in mean CCT between normal control eyes, NTG eyes or PACG eyes. CONCLUSIONS: PACG eyes had a CCT similar to that of NTG or normal eyes in Korean subjects.

PURPOSE: To evaluate the central corneal thickness (CCT) and corneal endothelial cell density (ENDO) in pseudoexfoliation syndrome. METHODS: Medical records of patients who underwent a preoperative examination for cataract surgery and an examination for glaucoma were retrospectively reviewed. The present study included 44 patients (59 eyes) and age- and sex-matched controls. The total pseudoexfoliation patients divided into 2 groups, such as pseudoexfoliation syndrome (28 eyes) and pseudoexfoliative glaucoma (21 eyes) .The intraocular pressure (IOP), CCT, ENDO, corneal curvature (CC) and axial length (AL) were measured. RESULTS: The total pseudoexfoliation group showed significantly higher IOP (p = 0.001), thinner CCT (p = 0.003) and lower ENDO (p = 0.037). The pseudoexfoliation syndrome group showed significantly thinner CCT (p = 0.010) and lower EDNO (p = 0.041), but no significant difference in IOP (p = 0.941). There was no significant difference in CCT (p = 0.060) and ENDO (p = 0.171) between the pseudoexfoliative glaucoma group and controls, but the pseudoexfolliative glaucoma group showed significantly higher IOP (p < 0.001). CONCLUSIONS: The pseudoexfoliation group showed thinner CCT which should be taken into consideration when evaluating IOP with the applanation tonometer and diagnosing glaucoma, especially in pseudoexfoliation syndrome patients.

PURPOSE: To evaluate the efficacy of topical 0.1% hyaluronate (HA) and 0.05% cyclosporine A on tear film parameters in dry eye syndrome patients. METHODS: Patients who were diagnosed with dry eye syndrome were treated with mbined with cyclosporine A (Group 2, 54 eyes). Ocular surface disease index (OSDI), tear film break-up time (BUT), Schirmer's test, and tear osmolarity were evaluated before treatment and at 1, 2, 3, and 6 months after treatment. RESULTS: OSDI was significantly improved at 2 months after treatment and Schirmer's test results significantly improved at 1 month after treatment in both groups. The BUT was significantly improved 3 months after treatment in Group 1 and at 1 month after treatment in Group 2. Tear osmolarity significantly improved at 1 month after treatment in both groups, but continuously improved up to 6 months after treatment only in Group 2. The BUT and Schirmer's test showed greater improvements in Group 2 than in Group 1. CONCLUSIONS: Combined treatment of topical 0.1% HA and 0.05% cyclosporine A may be more effective for improving dry eye syndrome.
