Pediatric ocular motor abnormalities: clinical features and neurological correlates

Insights
Pediatric ocular motor abnormalities like ophthalmoplegia and nystagmus often signal underlying neurological conditions. Early recognition of these eye movement disorders aids in differentiating neurological from ophthalmological causes for better patient care.
Area of Science:
- Ophthalmology
- Neurology
- Pediatrics
Background:
- Pediatric ocular abnormalities can indicate serious neurological or ophthalmological conditions.
- Comprehensive analysis of these associations is limited.
- Understanding these links is crucial for accurate diagnosis.
Purpose of the Study:
- To investigate the associations between specific pediatric ocular motor abnormalities and their underlying etiologies.
- To differentiate between neurological and ophthalmological causes of eye movement disorders in children.
Main Methods:
- Retrospective review of pediatric patients with ocular motor abnormalities (2005-2025).
- Classification of patients into neurologic (N group) and ophthalmologic-only (O group) etiology groups.
- Analysis of ocular signs, disease categories, and accompanying non-ocular symptoms.
Main Results:
- Ophthalmoplegia, vertical/torsional nystagmus, and ocular motor apraxia were more common in the neurologic group.
- Specific correlations found: ophthalmoplegia with brain tumors/cerebrovascular/demyelinating diseases; nystagmus/apraxia with congenital/metabolic/degenerative disorders.
- Associated symptoms like headache, vomiting, tone abnormalities, and ataxia correlated with specific neurological conditions.
Conclusions:
- Ocular motor abnormalities and certain systemic symptoms in children may indicate underlying neurological disorders.
- Isolated ocular manifestations can suggest neurodevelopmental disorders or ocular myasthenia gravis.
- Early differentiation of etiologies optimizes management and reduces unnecessary investigations.
Introduction:
Pediatric ocular abnormalities may indicate underlying neurological or ophthalmological disorders; however, comprehensive analyses remain limited. This study aimed to investigate associations between specific ocular motor abnormalities and their underlying etiologies.
Methods:
We retrospectively reviewed pediatric patients with ocular motor abnormalities presenting to our tertiary referral medical center between 2005 and 2025. They were classified by final diagnosis into the neurologic (N group) and ophthalmologic-only (O group) etiology groups. Associations among ocular signs, disease categories, and accompanying non-ocular symptoms were analyzed.
Results:
Among the 141 patients included, ophthalmoplegia, nystagmus, ocular motor apraxia, and ocular deviation were observed in 33, 85, 8, and 21 patients, respectively; six patients had overlapping ocular motor abnormalities. Ophthalmoplegia, vertical/torsional nystagmus, ocular motor apraxia, and upgaze deviation were more frequently observed in the N group (n = 70). Specific correlations with neurological conditions included ophthalmoplegia with brain tumors, cerebrovascular and demyelinating diseases; vertical/torsional nystagmus and ocular motor apraxia with congenital/metabolic/degenerative disorders; and ocular motor apraxia and upgaze deviation with neurodevelopmental disorders. Accompanying non-ocular symptoms showed significant correlations: headache/vomiting with brain tumors/cerebrovascular disorders, tone abnormalities with congenital/metabolic/degenerative disorders, and ataxia with demyelinating diseases. Isolated ocular symptoms most commonly occurred with neurodevelopmental disorders and ocular myasthenia gravis (MG).
Conclusion:
Pediatric patients presenting with ophthalmoplegia, vertical/torsional nystagmus, ocular motor apraxia, upgaze deviation, or associated systemic symptoms of headache/vomiting, tone abnormalities, or ataxia may have underlying neurological disorders. Even isolated ocular manifestations may indicate neurodevelopmental disorders or ocular MG. Early recognition may facilitate differentiation between neurological and ophthalmological etiologies, thereby optimizing patient management and reducing unnecessary diagnostic investigations.
