Presentation
Inheritance - congenital achromatopsia is transmitted in an autosomal-recessive trait Presentation - patients present in early childhood with nystagmus, abnormal visual behaviour or photophobia. Acuity is less than 20/200. [patient.info]
The streamlined format and evidence based medicine presented in the volume make this book the perfect reference for medical students, residents, general ophthalmologists and retina specialists. [books.google.es]
A patient with cone-rod dystrophy, who was examined thoroughly with biomicroscopy, fluorescein angiography, optical coherence tomography, and electrophysiology, is presented. [healio.com]
Various degrees of retinal atrophy are also present. [centogene.com]
The signs and symptoms of Cone-Rod Dystrophy may include: Very frequently present symptoms in 80-99% of the cases: Abnormality of retinal pigmentation Nyctalopia Photophobia Frequently present symptoms in 30-79% of the cases: Abnormality of color vision [dovemed.com]

- Peripheral Vision Loss
These features are typically followed by impaired color vision (dyschromatopsia), blind spots (scotomas) in the center of the visual field, and partial side (peripheral) vision loss. [ncbi.nlm.nih.gov]

Workup
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]
The retinopathy was initially classified as non-syndromic due to the very mild systemic manifestations that may be too subtle to be noted in routine ophthalmologic workup. [nature.com]
Treatment
Make optimal use of the newest drug therapies, including Anti-VEGF treatment for wet ARMD and bevacizumab treatment for complications of diabetes. [books.google.com]

Currently, there is no treatment to stop a person with Cone-Rod Dystrophy from losing their vision. [dovemed.com]
Are There Treatments for Cone-Rod Dystrophy? There is currently no cure or standard, proven treatment for cone-rod dystrophy. Some ophthalmologists believe that treatment with high doses of Vitamin A can slow the progression. [familyconnect.org]
Pedigree: Autosomal dominant Autosomal recessive Treatment Treatment Options: There is no treatment for these dystrophies but red-tinted lenses provide comfort and may sometimes improve acuity to some extent. Low vision aids can be helpful. [disorders.eyes.arizona.edu]
Prognosis
Prognosis - there is no progression. [patient.info]
Management and treatment Currently, there is no therapy that stops the evolution of the disease or restores the vision, and the visual prognosis is poor. [orpha.net]

(Etiology) Cone-Rod Dystrophy is caused by mutations in several different genes, each leading to a different type of the disorder The condition may be inherited in an autosomal dominant, autosomal recessive, X-linked, or mitochondrial inheritance patterns [dovemed.com]
Epidemiology
Summary Epidemiology The prevalence of CRDs is estimated at 1 in 40,000. Clinical description CRDs are characterized by retinal pigment deposits, visible on fundus examination, predominantly localized to the macular region. [orpha.net]

Pathophysiology
Ongoing genetic research continues to change the understanding of pathophysiology. Stargardt's disease and fundus flavimaculatus [ 3 ] There has been some question as to whether this condition is two diseases or one. [patient.info]
This may not only increase the confidence in a correct molecular diagnosis, but also confirms previous rare phenotypic disease characterizations for genes infrequently involved in the pathophysiology of MD/CCRD. [nature.com]
Prevention
Cone-Rod Dystrophy may not be preventable, since it is a genetic disorder. [dovemed.com]
