Imaging Studies
B-scan ultrasonography can aid in differentiating between serum and blood collected under or within the choroid (shown in the image below) and can help delineate against a retinal detachment. B-scan ultrasonography is also helpful to delimit and stage the extent of the detachment when media are not clear.
B-scan ultrasonography examination of choroidal detachment. Fluid appears to be serum on one side (upper) and blood on the other side (below). Retina-to-retina contact, or kissing choroidal detachment, is present.
Optical coherence tomography and wide field fundoscopy may also be used to discover and monitor choroidal detachment. [28, 29]

-
Serous choroidal detachment. Two lobes (ie, superotemporal, supranasal) of fluid accumulation are visible. The choroidal folds seen at the posterior pole are due to concomitant hypotony.

-
Kissing choroidal detachment. When the lobes of the detachment are sufficiently large, retina-to-retina contact occurs. If this is extended centrally, the clinical picture is described as kissing choroidals. The extension of the lobes of detachment/edema is important for the decision-making process regarding the clinical management.
-
Postoperative suprachoroidal hemorrhage. In this buphthalmic aphakic eye, suprachoroidal hemorrhage resulted in vitreous hemorrhage, retinal detachment, and extrusion of retina and blood through the pupil into the anterior chamber.
-
Drainage of suprachoroidal space. After the posterior sclerostomies are performed, gentle infusion in the anterior chamber through a paracentesis tract helps the globe to maintain a tone while the fluid exit from the suprachoroidal space is facilitated.
-
Drainage of suprachoroidal space. The hemorrhagic fluid is darker than fresh blood. Mechanical gaping of the radial incisions facilitates the egress of fluid.
-
Drainage of suprachoroidal hemorrhage. At least two quadrants, guided by B-scan images. Careful sclerostomies are performed at 4-5 mm from the limbus. The anterior chamber (AC) should be frequently reformed or a low-pressure AC infusion line should be placed. Gentle pressure on the surrounding sclera will help drainage. Serum is yellow and clear, blood is very dark red. Do not grab or pull from inside the sclerostomies. The technique is the same for drainage of serous choroidal detachment.
