H55-H59: Other disorders of eye and adnexa

H58: Other disorders of eye and adnexa in diseases classified elsewhere

The H58 group in the ICD-10 WHO 2016 classification pertains to "other disorders of eye and adnexa in diseases classified elsewhere". This broadly includes eye-related disorders that occur as complications or manifestations of other underlying diseases. Because this group is diverse, the specific causes, symptoms, and progressions of these conditions can vary significantly. However, they all predominantly affect the structures of the eye and its adnexa – the surrounding tissues and structures like the eyelids and tear ducts. Common symptoms may include pain, changes in vision, redness, swelling, or other eye discomfort. In general, symptoms may develop related to the primary disease's progression. For example, diabetes may lead to diabetic retinopathy, causing vision loss if not well controlled. Understanding the base condition and how it can affect the eye is critical in anticipating and responding to potential eye disorders in this category.
