Red eye : diagnostic clues

Assessing a patient with red eye in primary care is a common but critical task that requires a systematic approach to identify the underlying cause and determine the appropriate management strategy. The red eye can result from a wide range of conditions, from benign to sight-threatening. The primary goal is to differentiate between conditions that can be managed in the primary care setting and those that require urgent referral to an ophthalmologist.

Key elements of the assessment include a detailed patient history to explore symptoms and potential precipitating factors, a thorough physical examination focusing on visual acuity, pupillary reactions, presence of discharge, and the pattern of redness, as well as identifying any associated systemic symptoms. Understanding the distinction between localized and generalized redness, as well as the presence of corneal involvement or acute visual changes, is essential. This approach ensures timely and appropriate management, minimizing the risk of complications and preserving eye health and vision.
