Major subcategories include stimulus deprivation-induced amblyopia and toxic amblyopia. Stimulus deprivation-induced amblyopia is a developmental disorder of the visual cortex. A discrepancy between visual information received by the visual cortex from each eye results in abnormal cortical development. STRABISMUS and REFRACTIVE ERRORS may cause this condition. Toxic amblyopia is a disorder of the OPTIC NERVE which is associated with ALCOHOLISM, tobacco SMOKING, and other toxins and as an adverse effect of the use of some medications. 368.00 is a specific code that can be used to specify a diagnosis 368.00 contains 2 index entries ICD-9-CM Diagnosis 368.01 Strabismic amblyopia 368.01 is a specific code that can be used to specify a diagnosis 368.01 contains 2 index entries ICD-9-CM Diagnosis 368.02 Deprivation amblyopia 368.02 is a specific code that can be used to specify a diagnosis 368.02 contains 1 index entry ICD-9-CM Diagnosis 368.03 Refractive amblyopia 368.03 is a specific code that can be used to specify a diagnosis 368.03 contains 1 index entry ICD-9-CM Diagnosis 368.1 Subjective visual disturbances 368.1 is a non-specific code that cannot be used to specify a diagnosis ICD-9-CM Diagnosis 368.10 Subjective visual disturbance unspecified 368.10 is a specific code that can be used to specify a diagnosis 368.10 contains 7 index entries ICD-9-CM Diagnosis 368.11 Sudden visual loss 368.11 is a specific code that can be used to specify a diagnosis 368.11 contains 1 index entry ICD-9-CM Diagnosis 368.12 Transient visual loss 368.12 is a specific code that can be used to specify a diagnosis 368.12 contains 6 index entries ICD-9-CM Diagnosis 368.13 Visual discomfort Term generally used to describe complaints related to refractive error, ocular muscle imbalance, including pain or aching around the eyes, burning and itchiness of the eyelids, ocular fatigue, and headaches.
