Increased Risk of Refractive Errors and Amblyopia among Children with Ptosis: A Nationwide Population-Based Study.

Background: This study aimed to investigate the risk of refractive errors (astigmatism, myopia, and hyperopia) and amblyopia in children with ptosis and association between age at diagnosis of ptosis and subsequent risks of vision problems. Methods: Retrospective claims data from the Taiwan National Health Insurance Research Database (NHIRD) were analyzed. We identified 1799 children aged 0−18 years who were newly diagnosed with ptosis between 2000 and 2012 and 7187 individuals without the disease.

Association between oophorectomy and depression in patients with comorbidities: A nationwide cohort study in Taiwan.

Objective: This study investigated the long-term rates of depression after oophorectomy for benign gynecological conditions with or without comorbidities.

Materials And Methods: This retrospective cohort study examined data from the National Health Insurance Research Database (NHIRD) involving 8199 women aged ≥20 years who underwent unilateral or bilateral oophorectomy for benign gynecological conditions (cases) between 2000 and 2013 (index date). A second cohort consisted of 32,796 women who did not undergo oophorectomy (controls) who were matched 4:1 to cases by age and index year.
