What is Suprachoroidal hemorrhage?
What is Suprachoroidal hemorrhage?
Suprachoroidal hemorrhage (SCH) is 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.
When does a Suprachoroidal hemorrhage drain?
The classic recommendation has been to wait 10 to 14 days to allow liquefaction of any clot prior to drainage in order to maximize egress of hemorrhage with minimal manipulation. 1 Serial B-scan ultrasonography can also help determine when clot lysis occurs.
How do you drain a Suprachoroidal hemorrhage?
Consider inserting a cyclodialysis spatula into the suprachoroidal space to keep the cut-down open for egress of the hemorrhage and to clear clots that obstruct flow. Focal pressure applied to the anterior lip of the wound and/or ocular massage can help maximize drainage.
What causes choroidal hemorrhage?
Causes include blood dyscrasias; choroidal hemorrhage with extension; diabetic retinopathy; Eales’ disease; hypertensive retinopathy; juvenile retinoschisis; malignant melanoma; metastatic intraocular tumors; neural retinal neovascularization from any cause; neural retinal tears; retinal angiomas; retinoblastoma; …
What is Subhyaloid haemorrhage?
A SUBHYALOID hemorrhage is an intraocular collection of blood that remains contained in a self-created, previously nonexistent space, usually between the posterior limiting layer of the vitreous and the retina.
What causes a subretinal hemorrhage?
Subretinal hemorrhage can arise from the retinal and/or choroidal circulation. Significant subretinal hemorrhage occurs in several conditions, but most commonly is associated with age-related macular degeneration, presumed ocular histoplasmosis, high myopia, retinal arterial macroaneurysm, and trauma.
How do doctors drain blood from the brain?
Simple aspiration: The surgeon drills a small hole in the skull and drains the hematoma using a small rubber tube or catheter. This is a relatively noninvasive procedure, but it doesn’t always allow the surgeon to drain the hematoma completely.
