Distribution of rods and cones along a line passing through the fovea and the blind spot of a human eye [1]. A blind spot, scotoma, is an obscuration of the visual field.A particular blind spot known as the physiological blind spot, "blind point", or punctum caecum in medical literature, is the place in the visual field that corresponds to the lack of light-detecting photoreceptor cells on the ...
Blind spot (vision), also known as the physiological blind spot, the specific scotoma in the visual field that corresponds to the lack of light-detecting photoreceptor cells on the optic disc Optic disc , also known as the anatomical blind spot, the specific region of the retina where the optic nerve and blood vessels pass through to connect to ...
A scotoma may include and enlarge the normal blind spot. Even a small scotoma that happens to affect central or macular vision will produce a severe visual disability, whereas a large scotoma in the more peripheral part of a visual field may go unnoticed by the bearer because of the normal reduced optical resolution in the peripheral visual field.
Acute idiopathic blind spot enlargement syndrome (AIBSE) is a rare eye disease affecting the retina of the eye. It is basically a type of retinopathy which affects females more than males. Currently there is no treatment for this condition, but, it is usually self limiting.
Scotoma is a type of blindness that produces a small blind spot in the visual field typically caused by injury in the primary visual cortex. Homonymous hemianopia is a type of blindness that destroys one entire side of the visual field typically caused by injury in the primary visual cortex.
The blind spot can also be assessed via holding a small object between the practitioner and the patient. By comparing when the object disappears for the practitioner, a subject's blind spot can be identified. There are many variants of this type of exam (e.g., wiggling fingers in the visual periphery on the cardinal axes).

A "blind spot" is an area where someone cannot see: for example, where a car driver cannot see because parts of his car's bodywork are in the way; metaphorically, a topic on which an individual is unaware of their own biases, and therefore of the resulting distortions of their own judgements (see Bias blind spot).
