Macular Degeneration Information, and more. Eyeglasses that incorporate two different powers in each lens, usually near and distance corrections. Space between back iris and front face vitreous; filled with aqueous fluid. Consists layers that include rods and cones; bipolar, amacrine, ganglion, horizontal and mueller cells; and all interconnecting nerve fibers. Covering an amblyopic patient's preferred, to improve in other.
Pigmented layers (iris, ciliary body, choroid) that contain most intraocular blood vessels. Excision outer corneal layers (lamellae) with a computer controlled keratome (knife), usually as a part a refractive keratoplasty procedure. Sometimes called an internal hordeolum. Early stage is background retinopathy.
Light rays entering are bent unequally by different meridians, which prevents formation a sharp image focus on. Separation from underlying pigment epithelium. Device measuring an eye's refractive error with no response required from patient. Nourishes cornea, iris, and lens and maintains intraocular pressure.
Mesh-like structure inside at iris-scleral junction anterior chamber angle. Refractive condition in which there is a diminished power accommodation arising from loss elasticity crystalline lens, as occurs with aging.
Macular Degeneration InformationMay be associated with excessive tearing. Can be corrected by eyeglasses, contact lenses, or refractive surgery. Forms a thin membranous lining rear two-thirds globe. Acronym: Laser in situ keratomileusis.Can cause foreign body sensation, burning eyes, filamentary keratitis, and erosion conjunctival and corneal epithelium. Part that converts images from eye's optical system into electrical impulses that are sent along optic nerve transmission to brain. Usually becomes significant after 45. Examination anterior chamber angle through a goniolens (special type contact lens). Common after 60; sometimes an early sign. May be treated by prescription drugs or surgery.
