Where is the Suprachoroidal space?
The suprachoroidal space (SCS) is a potential space between the sclera and choroid that traverses the circumference of the posterior segment of the eye.
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.
What is subretinal injection?
The subretinal space, by definition, is the space between RPE cells and photoreceptors. In the subretinal space, injected material comes into direct contact with the plasma membrane of the photoreceptor, and RPE cells and subretinal blebs [9,41].
What is a vortex vein?
The vorticose veins, more commonly referred to as vortex veins, drain the ocular choroid. Some empty into the cavernous sinus through the superior orbital veins, whereas others drain into the pterygoid plexus through the inferior orbital veins.
What are kissing Choroidals?
Kissing choroidal is a serious ocular condition can caused by trauma. The management of kissing choroidal is immediate external drainage with or without vitrectomy, corticosteroid, amd cycloplegics. Although the management has given aggresively, the prognosis is poor.
Is choroidal detachment painful?
Serous choroidal detachments are typically associated with a low pressure in the eye and are usually only mildly uncomfortable. In contrast, hemorrhagic choroidal detachments are commonly painful, and often associated with a high intraocular pressure.
How often do you get eye injections for macular degeneration?
Your doctor injects these medications into the affected eye. You may need injections every four to six weeks to maintain the beneficial effect of the medication. In some instances, you may partially recover vision as the blood vessels shrink and the fluid under the retina absorbs, allowing some vision gain.
What causes subretinal fluid?
Possible causes include buckling surgery, cryocoagulation, and the high viscosity of SRF due to long-standing retinal detachment (2). Other reasons may be the breakdown of the blood-retinal barrier, and surgical trauma to the retinal pigment epithelium-Bruch’s membrane complex (3).
What is lattice degeneration of retina?
Lattice degeneration is a common peripheral retinal degeneration that is characterized by localized retinal thinning, overlying vitreous liquefaction, and marginal vitreoretinal adhesion. The condition is associated with atrophic retinal holes, retinal tears, and retinal detachments.
What drains into the vortex veins?
How many vortex veins are in the eye?
The vorticose veins, referred to clinically as the vortex veins, drain the ocular choroid. The number of vortex veins is known to vary from 4 to 8 with about 65% of the normal population having 4 or 5. In most cases, there is at least one vortex vein in each quadrant.
What is the choroid’s function?
Traditionally, the choroid has been assigned as its major functions, supply of oxygen and nutrients to the outer retina, light absorption (pigmented choroid), thermoregulation, and modulation of intraocular pressure.
What causes choroidal degeneration?
Primary atrophies that can lead to choroidal atrophy include primary choroidal atrophies, retinal degenerations (retinitis pigmentosa group), end-stage macular dystrophies, mutations of the peripherin/RDS gene, and disorders that cause angioid streaks, such as pseudoxanthoma elasticum.
