What does exophthalmos indicate about the position and size of the eye?

• A. Protrusion with abnormal size
• B. Abnormal position with normal size
• C. Normal position with abnormal size
• D. Normal position and size

Answer: (B)

The correct answer points to the condition where the eye appears abnormally positioned, typically protruding from the orbit, yet retains its normal size. Exophthalmos indicates a change in the position of the eye, often due to underlying conditions such as hyperthyroidism, tumors, or inflammation surrounding the eye. In such cases, although the eyeball may not be enlarged in its dimensions, it is displaced forward, resulting in noticeable protrusion. Understanding the nature of exophthalmos is crucial in veterinary ophthalmology, as it assists in diagnosing underlying health issues affecting the ocular or orbital structures. Other options either mischaracterize the relationship between size and position or fail to encompass the clinical significance of the condition correctly. The focus is on the abnormal positioning of the eye itself rather than an increase in its actual size, distinguishing exophthalmos from other ocular conditions.
