the pupil
The primary tool used to visualize the internal structures of the eye is called an ophthalmoscope. This instrument allows healthcare professionals to examine the retina, optic disc, and other internal components of the eye by shining a light and magnifying the view. Additional imaging techniques, such as optical coherence tomography (OCT) and fundus photography, are also used for detailed assessment of the eye's internal structures.
This is the outermost layer of the eye excepting the cornea. It is composed of dense fibrous tissue to protect the internal eye structures and is also where the external ocular muscles insert to allow you to move your eyes.
The outer eye refers to the visible part of the eye, including the eyelids, lashes, and outer corner structures. It provides protection for the more delicate internal structures of the eye, such as the cornea, iris, and lens. The outer eye also plays a role in lubricating the eye through tear production.
Orbital radiography is a medical imaging technique used to visualize the bones and soft tissues of the eye socket (orbit) and surrounding structures. It helps in the diagnosis of fractures, infections, tumors, and other conditions affecting the eye and its surrounding structures.
The fluid-filled chamber in the eye helps to maintain the shape of the eye and supports the structures within it. It also helps to nourish the eye by supplying nutrients and removing waste products. Additionally, the fluid plays a role in maintaining the eye's internal pressure for proper function.

No, you cannot see ribosomes with the unaided eye. Ribosomes are microscopic structures, typically measuring about 20 to 30 nanometers in diameter, which is well below the resolution limit of the human eye. They can only be visualized using powerful microscopes, such as electron microscopes, which can magnify objects at a much higher resolution.
Eukaryotic cells are small and have internal structures that can only be viewed at high magnification. Microscopes allow scientists to see these structures in detail, such as the nucleus, mitochondria, and other organelles, which are crucial for understanding cell function. Without a microscope, these structures would be too small to see with the naked eye.

Eye drops containing medications such as tropicamide or phenylephrine are commonly used to dilate the eyes for medical examinations or procedures. These drops work by causing the muscles in the iris to relax, allowing the pupil to open wider and let more light in for better visualization of the eye's internal structures.
"Fundus not visualized" means that the back part of the eye, including the retina and optic nerve, cannot be seen during an examination. This could be due to factors like cataracts, vitreous opacities, or poor dilation of the pupils. Further evaluation may be needed to fully assess the health of the eye.

Sclera does not belong because it is the tough, white outer layer of the eye, while choroid, vitreous humor, and retina are internal structures within the eye that play different roles in vision.
