Choroid detachment

Under normal circumstances, except around the optic disc, the sclera process, the vortex vein, and the ciliary nerve pass through the sclera at the equatorial region, the choroid and sclera are closely connected, and the choroid and sclera in most other areas are only connected by a small amount of fibrous connective tissue There is a potential gap between the two, this is the suprachoroidal space. The pressure in this cavity is equal to or slightly less than the intraocular pressure. If this pressure relationship is disrupted, fluid will accumulate in the upper choroid space called choroidal detachment. Due to the anatomical continuity of the ciliary body and the choroid, detachment of the choroid is often accompanied by detachment of the ciliary body.
