Question

the eye is a special sensory organ that enables vision. there are a variety of structures that work together to keep the eye healthy.

1. what would happen if a person has no lacrimal glands or if the person's lacrimal glands were clogged?

2. what would happen if the vitreous humor leaked out of the eyeball?

3. include structure and function in both explanation.

Answer 1

1. A decrease or lack of lacrimal gland secretion is the leading cause of aqueous tear deficient dry eye syndrome (DES). It has been suggested that DES is an inflammatory disorder that affects the ocular surface and the lacrimal gland.

2.  Vitreous hemorrhage is the extravasation, or leakage, of blood into the areas in and around the vitreous humor of the eye.The vitreous humor is the clear gel that fills the space between the lens and the retina of the eye. A variety of conditions can result in blood leaking into the vitreous humor, which can cause impaired vision, floaters, and photopsia.

Common symptoms of vitreous hemorrhage include:

Blurred vision

Floaters – faint cobweb-like apparitions floating through the field of vision

Reddish tint to vision

Photopsia – brief flashes of light in the peripheral vision

Small vitreous hemorrhage often manifests itself as "floaters." A moderate case will often result in dark streaks in the vision, while dense vitreous hemorrhage can significantly inhibit vision

3. Structure and function :

Vitreous humor :  The vitreous performs a vital role in protecting your eye. Most importantly, it helps it to hold its 'spherical' shape. The vitreous also comes in contact with the retina (the light-sensitive tissue at the back of the eye that acts like the film of a camera)

Lacrimal gland :  The lacrimal gland is located within the orbit above the lateral end of the eye. It continually releases fluid which cleanses and protects the eye's surface as it lubricates and moistens it. These lacrimal secretions are commonly known as tears
