Suprachoroidal hemorrhage (SCH)

A rare, but potentially vision threatening pathology that may manifest as a consequence of intraocular surgery. It occurs when blood from the long or short ciliary arteries fills within the space between the choroid and the sclera.[1] Suprachoroidal hemorrhages are classified in several ways. They may be categorized with respect to size and the extent of hemorrhage, relationship to intraocular surgery (intraoperative/expulsive or postoperative/delayed), or precipitating events (spontaneous, blunt/penetrating trauma or perioperative).[2] Chu et al notes that traumatic SCH behave differently from perioperative SCH and “should be considered a distinct entity.”[2] This report will focus mostly on SCH as it pertains to intraocular surgery.
