Cone dystrophy is usually present in early infancy or during childhood or early adulthood. However, the disorder has been reported to develop in individuals of all ages including older adults. [rarediseases.org]

Presentation[edit] The most common symptoms of cone dystrophy are vision loss (age of onset ranging from the late teens to the sixties), sensitivity to bright lights, and poor color vision. Therefore, patients see better at dusk. [en.wikipedia.org]

• Retinal Pigmentation

  However, the retinal pigment epithelium (RPE) rapidly becomes involved, leading to a retinal dystrophy primarily involving the macula. [en.wikipedia.org]

• Ataxia

  Cone dystrophy Fundus of a 34-year-old patient with cone rod dystrophy due to Spinocerebellar Ataxia Type 7 (SCA7). Note that the macular area, and also the mid periphery, are atrophic. [en.wikipedia.org]

The inclusion of fluorescein angiography in the workup of these patients is important since it can help detect many of these characteristic ophthalmoscopic features. [en.wikipedia.org]

Standard Therapies Treatment There is no cure for cone dystrophy. Treatment is directed toward the specific symptoms that are apparent in each individual. [rarediseases.org]

[citation needed] Treatment[edit] Though there is no treatment for cone dystrophy, certain supplements may help in delaying the progression of the disease. [en.wikipedia.org]
