The fovea, where this layer is absent, retains its normal orangered colour due to perfusion from the underlying choroidal vessels, resulting in the appearance of the “cherry red spot”. Retinal survival time has...

Although the laboratory findings were negative, cherry-red spots, progressive myoclonus and autosomal recessive...
We present a rare case of Tay-Sachs disease with retinal 'cherry-red spots' in a 19-month-old Malay child. Molecular genetic studies confirmed the diagnosis. The case highlights that 'cherry-red spot' is a useful clinical clue in Tay-Sachs disease and several other lysosomal storage disorders. It serves as an ideal illustration of the eye as a window to inborn error of metabolism.

He reported a cherry-red spot on the retina of a one-year-old patient, a patient who was also showing signs of progressive degeneration of the central nervous system [4] as manifested in the child?s physical and mental retardation [5]. This cherry-red spot is a characteristic that would eventually come to be associated with...
