Red eye evaluation is crucial for timely diagnosis and treatment. Simple tests and targeted questions help differentiate urgent cases from non-urgent ones, guiding appropriate patient referral.

Area of Science:

Ophthalmology
Primary Care Medicine

Background:

Red eye is a common symptom with diverse causes, including systemic and ophthalmological diseases.
Initial patient consultation is often with non-ophthalmologists, necessitating accurate urgency assessment.
Prompt diagnosis and treatment planning are vital for managing red eye conditions.

Purpose of the Study:

To review the differential diagnosis of red eye.
To provide guidance for primary care physicians in assessing red eye urgency.
To differentiate between non-critical and emergent red eye presentations.

Main Methods:

Selective literature search of PubMed publications up to August 2016.
Inclusion of authors' clinical and scientific experience.
Review of pertinent publications and clinical expertise.

Main Results:

Primary care physicians encounter 4-10 red eye patients weekly.
History, baseline tests, and symptoms (duration, laterality, pain) aid differential diagnosis.
Key criteria differentiate non-critical red eye from conditions requiring specialist referral or urgent surgery.

Conclusions:

Differential diagnosis of red eye can be rapidly narrowed with basic tests and questioning.
Urgent referral to an ophthalmologist is indicated for ocular emergencies.
Patients with uncertain diagnoses should also be promptly referred to an ophthalmologist.
