To observe and characterize subconjunctival lymphatics in patients with subconjunctival hemorrhages.
MethodsPatients 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.
ResultsApparent 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.
ConclusionsSubconjunctival lymphatics, which are not visible in normal ocular conditions, are evident on subconjunctival hemorrhages, especially after subconjunctival drug injection.
