MetadataShow full item record
The purpose of this prospective study was to investigate the association between convergence insufficiency (CI) and fourth cranial nerve palsy (SOP) in patients presenting at 4 clinics within Nationwide Children’s Hospital. A patient obtaining a new diagnosis of CI or SOP was then screened for the other diagnosis. The study consisted of a primary and revised analysis. The primary analysis included sixty subjects between the ages of 6 and 80 years of age were recruited with a new diagnosis of CI or SOP. Fifty-four patients were identified to have CI and 18 patients were identified to have SOP. SOP patients were split up into congenital (9) and acquired (9) groups. The primary analysis supported the association between SOP and CI (P<0.001). Revised analysis that included ALL inclusion criteria resulted in 18 subjects, 9 CI and 9 SOP. The revised analysis did not show anyone with a SOP and CI together.
