Retinal detachment is a disorder of the eye in which the retina peels away from its underlying layer of support tissue. [1] Initial detachment may be localized, but without rapid treatment the entire retina may detach, leading to vision loss and blindness. It is a surgical emergency.
Treatment. Surgeons can remove or peel the membrane through the sclera and improve vision by 2 or more Snellen lines. Usually the vitreous is replaced at the same time with clear (BSS) fluid, in a vitrectomy. Surgery is not usually recommended unless the distortions are severe enough to interfere with daily living.
It also depends on patient age and their visual acuity before surgery. For example, if the eye is healthy, but filled with blood, then vitrectomy can result in return of 20/20 eyesight. With more serious problems, such as a retina which has detached several times, final sight may be only sufficient to safely walk (ambulatory vision) or less.
A posterior vitreous detachment (PVD) is a condition of the eye in which the vitreous membrane separates from the retina. It refers to the separation of the posterior hyaloid membrane from the retina anywhere posterior to the vitreous base (a 3–4 mm wide attachment to the ora serrata).
A retinal implant is a visual prosthesis for restoration of sight to patients blinded by retinal degeneration. The system is meant to partially restore useful vision to those who have lost their photoreceptors due to retinal diseases such as retinitis pigmentosa (RP) or age-related macular degeneration (AMD).
December 11, 2019 at 10:23 AM. The "Today" show unfolded Wednesday without co-anchor Savannah Guthrie, who is undergoing retinal detachment surgery three weeks after suffering a serious eye injury.
A scleral buckle is one of several ophthalmologic procedures that can be used to repair a retinal detachment. Retinal detachments are usually caused by retinal tears, and a scleral buckle can be used to close the retinal break, both for acute and chronic retinal detachments.
Most eyes with CSR undergo spontaneous resorption of subretinal fluid within 3–4 months. Recovery of visual acuity usually follows. Treatment should be considered if resorption does not occur within 3–4 months, spontaneously or as the result of counselling.
Retinal hemorrhages, especially mild ones not associated with chronic disease, will normally reabsorb without treatment. Laser surgery is a treatment option which uses a laser beam to seal off damaged blood vessels in the retina.
Macular degeneration is a condition affecting the tissues lying under the retina, while a macular hole involves damage from within the eye, at the junction between the vitreous and the retina itself. There is no relationship between the two diseases. Depending upon the degree of attachment or traction between the vitreous and the retina, there ...
