Please refer to the image to answer the question I have Describe the texture, color, and function of the sheep eye. Does the iris change size at all (if so what causes it to change)? Is the cornea clear or cloudy?

Please label the following structure: A. Retina B. Sclera C. Choroid D. Cornea

retina disease in diabetes and hypertension Importance of prevention (hint:  regular retina exam with ophthalmoscope: what are signs of concern)

Select all structures that are part of the outermost layer of the eye. Sclera Cornea Uvea Choroid Retina

Recall that the eye is composed of three layers or "tunics" — the fibrous, vascular, and nervous layers — which enclose two cavities that are separated from each other by the lens. Review the components of these three layers by matching each description with the appropriate letter in the figure below: 1. Fluid in the anterior portion of the eye that provides nutrients to the lens and cornea   2. The "whites" of the eye   3. Area of the retina that lacks photoreceptors   4. Contains smooth muscle that controls the shape of the lens   5. Nutritive (nourishing) layer of the eye   6. Layer containing rods and cones   7. Gel-like substance that helps support the eyeball                    8. Pigmented smooth muscles that control pupil size   9. Most anterior component of the fibrous layer — your "window to the world"   10. Structure that changes shape to bend light toward rods and cones

Give typed explanation of all subparts otherwise leave it  Within the textbox below, define and identify the combining forms (Root, Suffix, Prefix, Combining vowel) of the following terms:     Example: Salpingopharyngeal = salping/o-pharyng-eal   4. Otoscope=   5. Rhinitis   6. Amblyopia   7. Astigmatism=   8. Corneal   9. Xerosis   10. Audiogram

Presbyopia is a condition in which a person's ability to adjust to changes in visual acuity diminishes or disappears entirely. Will she still require reading glasses after LASIK to correct her far vision? Explain.

(a) What is hypermetropia?(b) What are the two causes of this defect of vision?
