What is hyaloid membrane?
What is hyaloid membrane?
At least two parts have been identified anatomically. The posterior hyaloid membrane separates the rear of the vitreous from the retina. It is a false anatomical membrane. The anterior hyaloid membrane separates the front of the vitreous from the lens. Bernal et al.
What is hyaloid vasculature?
Hyaloid vasculature is one of the major blood supply sources in the developing eye and plays an important role in the growth and maturation of crystalline lens, vitreous, and retina1. It consists of a group of vascular components: hyaloid artery, vasa hyaloidea propria (VHP), and tunica vasculosa lentis (TVL).
What is an anterior hyaloid?
The anterior hyaloid membrane (AHM) is a thin layer of protein fiber condensation that defines the anterior border of the vitreous body [1]. Naturally, the AHM is firmly attached to the posterior lens capsule forming the ligament of Weiger and the retrolental patellar fossa.
What is Rrd in ophthalmology?
A rhegmatogenous retinal detachment (RRD) occurs when a tear in the retina leads to fluid accumulation with a separation of the neurosensory retina from the underlying RPE; this is the most common type of retinal detachment.
What is white of eye?
Sclera: the white of your eye. Conjunctiva: a thin layer of tissue that covers the entire front of your eye, except for the cornea.
What is optic cup?
The optic cup is the white, cup-like area in the center of the optic disc. The ratio of the size of the optic cup to the optic disc (cup-to-disc ratio, or C/D) is one measure used in the diagnosis of glaucoma. Different C/Ds can be measured horizontally or vertically in the same patient.
What is Prepapillary vascular loop?
Prepapillary vascular loop is a congenital anomaly of the optic disc that presents as an elevated and twisted bundle of vessels projecting into the vitreous cavity.
What is the posterior hyaloid face?
The term posterior hyaloid face is used. commonly to describe the outermost cortical layer of the. vitreous. Clinical diagnosis of a suspected posterior vitreous. detachment is based on the clinical history of new-onset.
What is macula off Rhegmatogenous retinal detachment?
Rhegmatogenous Retinal Detachment (RRD) is the separation of neurosensory retina from retinal pigment epithelium (RPE) in association with accumulation of sub retinal fluid (SRF) in the presence of one or more retinal breaks. A significant amount of visual loss occurs especially when macula is involved.
