[Management of acute visual loss in children]

Area of Science:

• Pediatric Ophthalmology
• Neuro-ophthalmology
• Child Neurology

Background:

• Acute visual loss in children necessitates urgent evaluation and treatment.
• Causes vary, involving the eyeball, optic nerve, or retrochiasmatic pathways.
• Psychogenic visual disturbances are common in school-aged children but should be diagnosed after excluding organic causes.

Purpose of the Study:

• To outline the diagnostic approach and management strategies for acute and rapidly progressive visual loss in children.
• To emphasize the differential diagnosis based on clinical presentation and etiology.
• To highlight the importance of multidisciplinary collaboration in managing pediatric visual disturbances.

Main Methods:

• Clinical assessment of visual loss, considering laterality (unilateral or bilateral) and progression (acute, transitory, or rapidly progressive).
• Evaluation of associated symptoms and funduscopic examination of the optic disc.
• Differential diagnosis including retinal diseases, optic neuritis, cortical blindness, epilepsy, migraine, trauma, and intracranial pathology.

Main Results:

• Unilateral visual loss can be easily overlooked.
• Acute total transitory visual loss may indicate epilepsy or migraine.
• Rapidly progressive visual loss suggests retinal disease, optic neuritis, or cortical blindness.
• Retinal hemorrhages may suggest trauma.
• Optic disc swelling can signify increased intracranial pressure or optic neuritis.
• Normal optic discs require ruling out organic causes before considering psychogenic vision disturbance.

Conclusions:

• Management hinges on clinical features, symptoms, and optic disc appearance.
• A collaborative approach involving ophthalmologists, pediatricians, and neuropediatricians is essential.
• Brain neuroimaging is critical in emergencies to detect intracranial masses and visualize optic pathways, guiding diagnosis and treatment.
