RESUMEN
PURPOSE: To investigate the distribution of visual acuity, refractive error, and axial length in 8-year-old children who participated in an additional survey in Yamanashi Prefecture of the Japan Environmental Children's Study (hereafter referred to as JECS-Y) conducted from 2019 to 2021. PARTICIPANTS AND METHODS: Eight-year-old children who participated in the JECS-Y study were subjected to noncycloplegic measurements of refractive error and axial length. If the uncorrected visual acuity was less than 20/20, the best corrected visual acuity was evaluated in accordance with the autorefraction data. A questionnaire was administered regarding the parent's history of eyeglass wear or contact lens use. RESULTS: Among the 400 participating children, the rate of uncorrected visual acuity of 20/20 or better in both eyes was 70.4%. The mean equivalent spherical equivalent error for both eyes was -0.366 ± 1.016 D. The mean axial length was 23.08 ± 0.225 mm in all patients. The males showed significantly longer axial length than the females despite no differences in body height. There was a significant correlation between axial length, spherical refractive, and uncorrected visual acuity. The children of parents with a history of wearing eyeglasses or contact lenses showed a significantly more myopic equivalent refractive error than those without a history. CONCLUSIONS: This study clarified the current state of refractive error in 8-year-old children and the association of inheritance with refractive error. In addition, the axials were significantly longer in male patients.
RESUMEN
PURPOSE: To investigate how many tests need to be performed to adequately assess intraocular pressure (IOP) diurnal change using a self-measuring rebound tonometer among glaucoma patients. SUBJECTS AND METHODS: Adult patients with primary open-angle glaucoma were included. IOP was measured in the morning (6 AM to 9 AM), afternoon (12 PM to 3 PM), and at night (6 PM to 9 PM) for seven consecutive days. Twenty-four (7 males and 17 females, mean age 59.5 ± 11.0 years) patients who successfully measured IOP at least three times per day during the correct time periods for four days were subjected to analysis. RESULTS: The IOP rhythm was significantly greater on the first day of measurement (6.6 ± 3.6 mmHg) than that averaged during subsequent days (4.4 ± 2.2 mmHg). The time of the highest and lowest IOP measurements on the first day of IOP measurement and during the entire measurement period coincided in 72.9% and 64.6% of cases, respectively. The concordance rate of the highest IOP time between the whole measurement period and each measurement day was less than 60%. CONCLUSION: The diurnal IOP rhythm measured by the patients themselves was not consistent, and multiple days of measurements may be necessary to correctly assess diurnal IOP rhythm.
RESUMEN
RATIONALE: Brolucizumab is a novel anti-vascular endothelial growth factor agent with clinical trials demonstrating excellent efficacy for neovascular age-related macular degeneration (AMD) in both visual and anatomic outcomes. However, there is concern of intraocular inflammation (IOI), and we propose concurrent subtenon triamcinolone acetonide (STTA) to prevent IOI. PATIENT CONCERN: A 73-year-old man was treated with aflibercept for neovascular AMD in his right eye. Despite 11âmonths of monthly intravitreal aflibercept injections, optical coherence tomography demonstrated persistent exudation. Ten days following his second brolucizumab injection, the patient presented with decreased vision due to vitritis in his right eye. DIAGNOSIS: Brolucizumab-related IOI in neovascular AMD refractory to aflibercept. INTERVENTIONS: A combination therapy involving of intravitreal brolucizumab and STTA. OUTCOMES: The anti-vascular endothelial growth factor inhibitor was changed back to aflibercept; however, exudation persisted. Therefore, a combination therapy involving STTA (5âmg/0.5âmL) and intravitreal injection of brolucizumab (6.0âmg/0.05âmL) was performed to treat the exudation and as prophylaxis to recurrent IOI. Combination therapy achieved no recurrent IOI and resolution of exudation with 8-week treatment intervals. LESSONS: This case might indicate that STTA is not only an optimal treatment option for brolucizumab-related IOI but also a preventive agent for this condition.
