Diagnosis of Achromatopsia:
Clinical Opthalmological examination will be done for
diagnosing Achromatopsia.
Psychological examination (i.e. color vision),
electrophysiological testing (i.e. electroretinography ERG) will be done.
Optical coherence tomography will show progressive
disruption, in few cases, along with loss of outer or inner segment junction of
photoreceptors & attenuation of retinal pigment epithelium (RPE) within
macular area.
Verification of the diagnosis of Achromatopsia will be done
through molecular genetic analysis of responsible genes.
Blue cone monochromatism or BCM, etc cone dystrophies along
with cerebral achromatopisa will be done as a part of differential diagnosis.
At-risk couples can go for prenatal diagnosis at specialized
labs so as to know if their child will have chances to get this Achromatopsia
disorder.
