This involves the replacement of the vitreous to prevent further damage to the retina.Whether you’re trail running, wheeling down a mountain or turning the pedals on the road, this sunglass offers the ultimate in performance for any in-the-field excursion. The surgery involves implanting a tiny electrode chip or retinal prosthesis into the retina. If you have severe vision loss, your retinal specialist may suggest surgery. This is common, especially if you have wet macular degeneration or diabetic retinopathy. Your eye doctor may suggest injecting medication into your eye. It’s used to repair retinal detachment using silicone material. This may be used together with cryopexy or laser photocoagulation to treat retinal detachment. Air or gas injection (pneumatic retinopexy).Cryopexy involves freezing the retina to allow healing. This is a freezing process used to treat retinal tears. This is the shrinking of abnormal cells, such as in the case of diabetic retinopathy. Treatment for retinal diseases is focused on either stopping or slowing the progression of damage, improving or restoring your vision, or managing a chronic condition. Seek medical advice if you experience flashes, reduced vision, floaters, or persistent pain in your eye. Retinitis pigmentosa causes night blindness and loss of side vision (peripheral vision) When to See a Doctor This is a rare genetic disorder that involves loss of retinal cells. The hole may develop due to trauma or abnormal traction within the eye. This is a minor defect characterized by a small hole at the center of the macula. This condition mainly affects men in their 30s and 40s. Central Serous Retinopathy (CSR)ĬSR is a condition where a cyst develops in the central retina. Retinal Tear or DetachmentĪ retinal tear or detachment occurs when the retina is torn or detached from other parts of the eye that provide nourishment and function.Ī retinal tear or detachment is considered an ocular emergency. This affects central vision, causing a blurry, distorted view or a blind spot at the center of your visual field. Macular degeneration affects the center of the retina. If you have diabetes, the tiny blood vessels at the back of your eye may weaken and leak into the retina, causing it to swell. In most cases, visual issues may occur.īelow are common retinal problems: Diabetic retinopathy Retinal diseases vary widely, and they can affect any part of your retina. The brain interprets the signals into images, enabling you to see the shape, design, color and other details of the objects you look at. 4 The signals are then sent to the brain through the optic nerve. The retina converts the images into electrical signals. The Images come in through the cornea and eye lens and are focused on the retina. Ganglion cell axons are long fibers that make up the optic nerve. It allows the exit of the retinal ganglion cell axons and the entry and exit of the retinal blood vessels. Optic Nerve HeadĪlso known as the optic disc, the optic nerve head is the face of the optic nerve bundle as it enters the back of the eye. The macula contains a high concentration of photoreceptor cells (cones and rods). The macula is 5mm in diameter and is responsible for your central vision, color vision, and fine detail. The optic nerve is a bundle of fibers that transmit visual messages to the brain for interpretation, which enables you to see. The posterior pole is the back part of the retina that includes the macula and optic nerve. The ora serrata is the junction between the non-light-sensitive area and the light sensitive area of the retina.ĭuring an eye examination, an ophthalmologist will look at the following important parts of the eye: The Posterior Pole It’s thicker towards the optic nerve head and increasingly thinner at the ora serrata. The retina is about 0.5 millimeters thick. The human retina measures 30 to 40 mm and covers roughly 1,100 square mm in each eye.
