Bloody tears (hemolacria) can signal hidden eye conditions. This case highlights pyogenic granuloma as a cause, emphasizing thorough eyelid examination for diagnosis.

Area of Science:

Ophthalmology
Oculoplastics
Pathology

Background:

Hemolacria, or bloody tears, is a rare condition with diverse causes.
Prompt diagnosis and management are crucial for effective treatment.

Observation:

A 21-year-old female contact lens wearer experienced recurrent unilateral bloody tears.
Examination revealed a pyogenic granuloma on the palpebral conjunctiva of the upper eyelid.

Findings:

Surgical excision confirmed the diagnosis of pyogenic granuloma.
This conjunctival lesion was the source of the hemolacria.

Implications:

Unilateral hemolacria warrants investigation for occult conjunctival lesions like pyogenic granuloma.
