Objective: To evaluate the etiology and incidence of III., IV., and VI. cranial nerve palsies in pediatric population.
Institution: Department of Ophthalmology, Dokuz Eylul University School of Medicine, Izmir.
Materials and Methods: Records of 65 pediatric patients with III., IV. or VI. cranial nerve palsy examined in the Department of Ophthalmology, Dokuz Eylul University School of Medicine between 1994 and 1999 were retro-spectively reviewed.
Results: Abducens nerve palsies accounted for the majority of the cases (44.6%); followed by oculomotor (26.2%), and trochlear (20%) nerves. Multiple cranial nerve palsies were the least common group. Bilateral involvement was present in 15 cases (23.1%) and was most frequent among the patients with sixth nerve palsy. Fourteen cases (21.5%) were congenital and 51 (78.5%) were ac-quired. Trauma was the most frequent cause in patients with third nerve palsy, congenital cases were more common in patients with IV. nerve palsy and neoplasms were predominant in children with VI. nerve palsy.
Conclusion: Diagnostic approach should be more fastidious in pediatric population as neoplasms and trauma are more common etiologic factors in childhood palsies and a cra-nial nerve palsy of undetermined origin is very rare in children.Keywords: Abducent nerve palsy, Oculomotor nerve palsy, Trochlear nerve palsyTürkiye Klinikleri Oftalmoloji 2003, 12:139-144
