Spontaneous inferior subconjunctival haemorrhages in association with circumferential drainage blebs

Aim To describe an association of spontaneous inferior subconjunctival haemorrhages in eyes with circumferential drainage blebs following trabeculectomy. Methods Observational case series. Patients with multiple episodes of spontaneous inferior subconjunctival haemorrhage following trabeculectomy (with or without antimetabolite) and circumferential blebs are presented. All patients described had multiple episodes. A possible mechanism is discussed. Results The number of spontaneous haemorrhages ranged from two to more than 10. All individual haemorrhages resolved spontaneously without adverse sequelae Conclusions A new clinical presentation of inferior subconjunctival haemorrhage in association with circumferential blebs is described.
