Descemet membranotomy to treat pre-Descemet haematoma after deep sclerectomy and anterior segment-OCT related findings: A presentation of two clinical cases

Case presentation An 81 year-old woman and a 63 year-old man developed a pre-Descemet haematoma after deep sclerectomy (DS), the former during the surgery itself and the latter during the early post-operative period. The surgical technique is described that led to the evacuation of the haematoma and the preservation of the integrity of trabeculo-Descemet membrane. The anterior-segment OCT findings after surgery are also presented. Conclusions These are the first reported cases of pre-Descemet haematoma after DS that have been successfully repaired by an ab interno Descemet membranotomy. Surgeons should be aware of this rare, but potentially sight-threatening, complication.
