“…[1][2][3][4][5] The mechanism of SCD includes both hypotony and inflammation, which lead to an increased tendency for fluid accumulation in the suprachoroidal space. Serous choroidal detachment can also occur in the setting of intraocular tumors, 6,7 nanophthalmos, 8 ocular inflammatory conditions, 9 carotid-cavernous fistula, 10 and panretinal photocoagulation, 11 secondary to certain medications, 12 and spontaneously. 13 In HCD, the postulated mechanism is initial hypotony, with or without a preceding serous choroidal effusion, resulting in stretching and rupture of a long or short posterior ciliary artery.…”
