Abstract
Purpose
To observe and characterize subconjunctival lymphatics in patients with subconjunctival hemorrhages.
Methods
Patients who visited our clinic with subconjunctival hemorrhage resulting from ocular trauma, or subconjunctival injection of gentamicin and betamethasone during a cataract operation, were included in this study. Subconjunctival hemorrhages and subconjunctival lymphatics were observed using slit lamp biomicroscopy.
Results
Apparent dilated lymphatics were found in one patient with subconjunctival hemorrhage after rubbing of the eye; thin lymphatics were found in 10 patients with traumatic subconjunctival hemorrhages; and apparent dilated lymphatics were found in 10 patients after subconjunctival injection. Slit lamp biomicroscopy using a green filter allowed easy visualization of subconjunctival lymphatics.

Well visible dilated conjunctival lymphatics (white arrow) and lymphatic cyst (black arrow) are shown. More dilated lymphatics than those in trauma cases are seen.
