VII: Diseases of the eye and adnexa
H49-H52: Disorders of ocular muscles, binocular movement, accommodation and refraction
Disorders of ocular muscles, binocular movement, accommodation and refraction are a group of eye conditions that affect the muscles controlling eye movement, and the eye's ability to focus. These disorders may be inherited, or caused by nerve damage, injury, or certain medical conditions. Common symptoms include uncontrolled eye movements, eyes that appear to not align correctly, blurred vision, double vision, head tilt, difficulty reading, and problems with eye-hand coordination. These conditions often develop gradually over time and can result in strabismus (crossed eyes), nystagmus (uncontrollable eye movements), or impaired accommodation and refraction, affecting the eye's ability to adjust focus and bend light correctly. These disorders primarily affect the visual system and can potentially impact daily life activities.
