AbstractAim: The aim of the present study was to determine the clinical presentation and document the etiological factors in patients with ocular motor nerve palsy involving 6th cranial nerve.
Methods: The cross-sectional study was conducted at a tertiary care center in western India from September 2020 to October 2022 and33 consecutive patients presenting with cranial nerves were included in study from wards and opd in a tertiary care center and sample size was calculated according to win pepi method.
Results: The Mean±SD age of the patients were 50±15.7 years and the range were 11-78 years. Majority of the patients were males (51.5%), followed by females (48.5%). Left side was affected among 51.5%, while 48.5% had their right side affected. RTA was the most common in 6th nerve and hypertension (16%) were found as majority among the sixth nerve palsies. Majority of the patients had a visual acuity of 6/9 (15.2%) and 6/24p (12.1%).
Conclusion: Abducens was the most commonly involved nerve while trauma was most common etiology in our study. The most common cause for cranial nerve palsy was vascular i.e diabetes and hypertension. Therefore, early diagnosis and proper management of these systemic diseases can prevent ocular motor nerve palsies and its complications. Our study evaluated ptosis, diplopia, visual impairment, complete ophthalmoplegia, ocular deviation as some of the most common causes for ocular motor nerve palsies.
