A nurse measures a patient height and weight and calculate his BMI. Patient BMI is 37. Classify according to this BMI results?

a) The patient is unable to see in half of the visual field (same visual field) in each eye:

Homonymous hemianopsia is a condition where there is a loss of vision in the same side of the visual field in both eyes. This occurs due to damage to the visual pathways after the optic chiasm, often from a stroke or brain injury, resulting in the loss of either the right or left visual field in both eyes.

b) The patient can see from one eye but not through the other one:

This description fits a condition called monocular blindness, which is typically caused by damage to the optic nerve before it reaches the optic chiasm. Homonymous hemianopsia involves both eyes and specific visual fields, not complete loss of vision in one eye.

c) The patient is unable to see in half of the visual field (opposite visual field) in each eye:

This option describes bitemporal hemianopsia, which results in loss of vision in the outer (temporal) fields of both eyes and is often due to damage at the optic chiasm. Homonymous hemianopsia involves the same side of the visual field in both eyes, not the opposite visual fields.

d) No visual impairment:

Homonymous hemianopsia is characterized by significant visual impairment, specifically the loss of half the visual field in both eyes on the same side. Therefore, it is incorrect to say there is no visual impairment with this condition.

A) Loss of vision in one eye:

Loss of vision in one eye is not related to hyperopia (farsightedness). This condition could be due to various other causes such as retinal detachment, optic neuropathy, or trauma, but it does not describe the refractive error associated with hyperopia.

B) Clear vision of nearby objects, but difficulty seeing distant objects:

This description pertains to myopia (nearsightedness), where individuals can see nearby objects clearly but struggle with seeing distant objects. Hyperopia is the opposite, involving difficulty with near vision rather than distance vision.

C) Clear vision of distant objects, but difficulty seeing nearby objects:

Hyperopia, or farsightedness, is characterized by clear vision of distant objects while nearby objects appear blurry. This occurs because the eye's light focuses behind the retina rather than directly on it, making close-up tasks like reading challenging.

D) Blurry vision of both distant and nearby objects:

Blurry vision of both distant and nearby objects is not specific to hyperopia and may indicate other eye conditions such as astigmatism or severe refractive errors that affect overall visual acuity, rather than the specific issue of near vision seen in hyperopia.
