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]

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]
Serious effects on visual acuity (light perception only) were present in 10 other patients; however, their mean age was 60.3 years. All other patients retained some visual acuity. [blindness.org]

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]
