In time the gas will dissipate and be replaced by the eye’s own fluids (aqueous humor). The vitreous will be replaced with a gas. Once the vitreous is removed, a freezing instrument or a laser is used to seal any tears in the retina. The second incision is used to insert a fiber-optic light to provide illumination of the eye, and the third is for any instruments that are used, including a “vitrector” for the removal of the vitreous.Ī vitrector is an oscillating microscopic cutter that slowly removes the vitreous. Through one incision a constant flow of fluid is passed into the eye. The surgery consists of making three small needle-sized incisions (about the width of an eyelash) into the white part of the eye (sclera). If patients prefer not to be awake during the procedure they can be given intravenous sedation or a general anesthesia. A heavy sedative is administered and then Lidocaine is injected around the eye to numb it. The SurgeryĪ vitrectomy is usually performed using local anesthetic. Then gas is injected into the eye to help keep the retina in place and prevent any fluid from leaking from the repaired tears and into the subretinal space. The surgery removes the vitreous gel from the eye, pushes the detached retina back into place, and seals any retinal tears in the retina. Vitrectomy for retinal detachment repair is an alternative method to scleral buckle or pneumatic retinopexy.Ī vitrectomy is a common surgical repair for a detached retina.

Vision loss is usually sudden and treatments may be required in an attempt to improve vision and/or to prevent total blindness from complications of the vascular occlusions. Both arteries and veins can be blocked retinal vascular occlusions. Periodically the retinal vessels can become occluded or blocked. There is presently no treatment for dry macular degeneration approved by the FDA. Treatment usually involves intravitreal injections of anit-VEGF. The “wet” form is also called neovascular AMD (nAMD).īoth types of macular degeneration affect both eyes and are progressive, but the wet form can steal vision quickly, is associated with leaky abnormal blood vessels and bleeding. Macular degeneration (AMD) comes in two forms: dry AMD and wet AMD. In most scenarios, these are procedures only offered by a retina specialist. A retina specialist is adept at treating the two most common causes of vision loss from diabetes: diabetic macular edema and proliferative diabetic retinopathy.Ĭommon treatments used by retina specialists include: anti-VEFG injections, steroids, laser and surgery. Advanced Diabetic Retinopathyĭiabetic retinopathy can cause blurry vision and blindness. Intraocular antibiotics, anti-fungals and/or vitrectomy surgery may be necessary to prevent catastrophic vision loss. Prompt referral to a retina specialist is paramount in preventing loss of vision from infection. This usually occurs following recent eye surgery, but can also follow penetrating eye injury. Retina Specialist and EndophthalmitisĮndophthalmitis is infection inside the eye. Glass, metals and organic material need to be removed by performing a vitrectomy, the principal operation performed by a retina specialist. While not commonplace, intraocular foreign bodies may occur with any penetrating eye injury. Retinal detachments will often require surgery. Retinal tears can be treated with either cryotherapy or laser. While most new floaters and flashes are NOT associated with a retinal tear, the only way to make sure you are not at risk for developing a retinal detachment is have a complete dilated eye exam. Retinal tears may be asymptomatic, but often are associated with the sudden onset of new floaters or flashes usually due to a posterior vitreous detachment. Retinal tears can cause a retinal detachment. Retinal Tear, Retinal Detachment, Retina Specialist Here are 7 more common reasons why you may be referred to a retina specialist. Additional training years are required to focus attention in this special area. A retina specialist is an ophthalmologist who has extra-training in diseases and surgery of the retina.
