Visualization of Subconjunctival Lymphatics and Its Significance

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. Conclusions: Subconjunctival lymphatics, which are not visible in normal ocular conditions, are evident on subconjunctival hemorrhages, especially after subconjunctival drug injection.
