[A case of erythropsia]

Area of Science:

• Ophthalmology
• Neuro-ophthalmology

Background:

• Erythropsia, characterized by red vision, is a transient visual disturbance.
• It represents a form of chromatopsia, an impairment in color perception.

Observation:

• Patients perceive all objects with a uniform reddish tint.
• This symptom often causes patient alarm due to its unusual nature.

Findings:

• Erythropsia is a little-known condition, typically transient.
• Potential causes range from benign factors like post-operative cataracts and drug toxicity to severe conditions such as vitreous hemorrhage.

Implications:

• Understanding the diverse etiology of erythropsia is crucial for accurate diagnosis.
• Prompt medical evaluation is necessary to rule out sight-threatening conditions associated with red vision.
