Vitreous membrane: The vitreous membrane (or hyaloid membrane or vitreous cortex) is a layer of collagen separating the vitreous humour from the rest of the eye. At least two parts have been identified anatomically.Anterior segment mesenchymal dysgenesis: Anterior segment dysgenesis (ASD) is a failure of the normal development of the tissues of the anterior segment of the eye. It leads to anomalies in the structure of the mature anterior segment, associated with an increased risk of glaucoma and corneal opacity.Posterior vitreous detachment: A posterior vitreous detachment (PVD) is a condition of the eye in which the vitreous membrane separates from the retina.Uveoparotitis: Uveoparotitis is a symptom of sarcoidosis. It describes a chronic inflammation of the parotid gland and uvea.Guiding Eyes for the Blind: Yorktown Heights, New YorkRetinal regeneration: Retinal regeneration deals with restoring retinal function to vertebrates so impaired.Optic disc pit: An optic disc pit is a congenital excavation (or regional depression) of the optic nerve head resulting from a malformation during development of the eye. Optic pits are important because they are associated with posterior vitreous detachments (PVD) and even serous retinal detachments.Pars plana: The pars plana is part of the uvea, choroidea, one of the three layers that comprise the eye. As a part of the ciliary body, it is about 4 mm long, located near the point where the iris and sclera touch and is scalloped in appearance.Aqueous humour: The aqueous humour is a transparent, gelatinous fluid similar to plasma, but containing low protein concentrations. It is secreted from the ciliary epithelium, a structure supporting the lens.Lens Controller: A Lens Controller is device that controls motorized photographic lens functions such as zoom, focus, and iris or aperture.Kruegle, Herman (2007).Neuro-ophthalmology: Neuro-ophthalmology is an academically-oriented subspecialty that merges the fields of neurology and ophthalmology, often dealing with complex systemic diseases that have manifestations in the visual system. Neuro-ophthalmologists initially complete a residency in either neurology or ophthalmology, then do a fellowship in the complementary field.Ciliary body: The ciliary body is a part of the eye that includes the ciliary muscle, which controls the shape of the lens, and the ciliary epithelium, which produces the aqueous humor. The ciliary body is part of the uvea, the layer of tissue that delivers oxygen and nutrients to the eye tissues.New Zealand rabbitCollagen
