Retinal tufts increase the risk of a retinal tear or a detached retina, although the risk is not high- 1% of tufts are thought to lead to retinal detachment. [ 2 ] [ 6 ] In addition if there is retinal thinning near a zonular traction tuft, there is an increased risk of retinal detachment.
Fundus of geographic atrophy. Geographic atrophy (GA), also known as atrophic age-related macular degeneration (AMD) or advanced dry AMD, is an advanced form of age-related macular degeneration that can result in the progressive and irreversible loss of retinal tissue (photoreceptors, retinal pigment epithelium, choriocapillaris) which can lead to a loss of central vision over time.
Choroideremia (/ k ɒ ˌ r ɔɪ d ɪ ˈ r iː m i ə /; CHM) is a rare, X-linked recessive form of hereditary retinal degeneration that affects roughly 1 in 50,000 males. The disease causes a gradual loss of vision, starting with childhood night blindness, followed by peripheral vision loss and progressing to loss of central vision later in life.
It most commonly occurs in people over the age of fifty and in the United States is the most common cause of vision loss in this age group. [1] [3] About 0.4% of people between 50 and 60 have the disease, while it occurs in 0.7% of people 60 to 70, 2.3% of those 70 to 80, and nearly 12% of people over 80 years old. [3]
Usually, this happens slowly over time and does not cause any symptoms, and medical intervention is neither needed nor recommended. Sometimes other retinal problems (such as tears, breaks, or holes) may be present along with lattice degeneration. However, these problems may also be distinct from or independent of lattice degeneration itself.
The prognosis for CSR is generally excellent. While immediate vision loss may be as poor as 20/200 in the affected eye, clinically, over 90% of patients regain 20/25 vision or better within 45 days. [1] Once the fluid has resolved, either spontaneously or through treatment, distortion is reduced and visual acuity improves as the eye heals.
Impairment of a person with 20/20 vision usually ends up being about 20/40 or 20/60, but can be better or far worse. [ 7 ] A doctor examining an eye with retinopathy may be able to see no signs at all, or a slight macular edema , which is a sort of blister on or under the macula , an oval colored spot normally visible to an eye doctor on each ...
Cherry red spot in a person with central retinal artery occlusion. Central retinal artery occlusion is characterized by painless, acute vision loss in one eye. [1] Upon fundoscopic exam, one would expect to find: cherry-red spot (90%) (a morphologic description in which the normally red background of the choroid is sharply outlined by the swollen opaque retina in the central retina), retinal ...
