Delayed suprachoroidal hemorrhage after Descemet Stripping Automated Endothelial Keratoplasty (DSAEK)

Abstract

This study, a case series of 2 patients and a literature review, aims to describe the second and third known cases of delayed suprachoroidal hemorrhage after Descemet stripping automated endothelial keratoplasty. The suprachoroidal hemorrhage is defined as the presence of blood in the suprachoroidal space; final visual acuity is rarely greater than 0.1 (decimal scale). Both cases presented had known risk factors: high myopia, previous ocular surgeries, arterial hypertension, and being under anticoagulant therapy. The diagnosis of delayed suprachoroidal hemorrhage was made at the 24-h follow-up visit, as they recalled a sudden and tremendous acute pain hours after surgery. Both cases were drained through a scleral approach. Delayed suprachoroidal hemorrhage is a rare but devastating consequence that can occur after Descemet stripping automated endothelial keratoplasty. Awareness of the most critical risk factors allows for early identification, which is of paramount importance for the prognosis of these patients.
