Cyanopsia is a visual condition characterized by a blue tint in vision, caused by the inhibition of cone phosphodiesterase enzymes that regulate cyclic guanosine monophosphate levels and light response properties of rods and cones. It is one of the types of dyschromatopsia, which also includes xanthopsia and chloropsia, and is often accompanied ...
The BFIOLs were developed to reduce cyanopsia, address chromatic aberration, and improve contrast sensitivity in different lighting conditions, as well as to prevent short-wavelength light reaching the retina thus potentially reducing the risk of developing age-related macular degeneration. Further design development of the BFIOLs was to mimic ...
A case report of a patient who developed cyanopsia in the right eye as an early sign of a nasal cavity mass compressing the optic nerve. The article discusses the possible mechanisms of cyanopsia and its clinical implications for optic neuropathy diagnosis.
'Cyanopsia' is a rare side effect of some drugs, such as sildenafil and vardenafil, that can change the color vision. Learn more about the symptoms, causes and treatments of 'Cyanopsia' and other similar conditions.
Congenital dyschromatopsia occurs in approximately 8.0%-8.7% in men and approximately 1% in women. 2 It arises from disorders in the genes coding, expressing or involved in the operation of cone photopigments. 2 It is bilateral, symmetrical and generally affects the entire visual field. Rod monochromatism causing achromatopsia is a congenital cone photoreceptor disorder affecting about 1 in ...
We evaluated cyanopsia by means of achromatic-point settings at several time points started from the day before intraocular lens (IOL) implantation for cataract removal surgery. We intensively measured the initial drift in color appearance; we started the measurement less than 30 min after eyepatch removal, and the measurement continued for ...
