Which common familial ocular disorder should you record during a patient's history?

Keratoconus is the correct answer because it is a specific ocular disorder that can have a hereditary component, making it pertinent to record in a patient's history. This condition involves the progressive thinning and bulging of the cornea, which can lead to visual distortion and increased sensitivity to light. Knowing about a family history of keratoconus can help healthcare providers assess the risk of the condition in patients and implement early monitoring or interventions.

Other familial conditions listed, such as scoliosis, hemophilia, and hypercholesterolemia, do not primarily affect the eyes. While they may have familial patterns and be significant in a medical history, they are not directly ocular disorders and would not typically be prioritized in an eye care setting. To effectively understand a patient's ocular health, especially in relation to disorders that could affect vision or eye structure, documenting a history of keratoconus becomes crucial.
