3. Abrasion - ANS-Fit of lens that is too flat. Foreign body gets trapped under lens. Eye
Patch overnight.
4. Acanthamoeba - ANS-extremely serious infection. caused by a parasite in water. very
painful, red eye that does not respond to conventional treatment.
5. adnexa - ANS-extraocular structures of the eye which include the eyelids, the orbit,
lacrimal glands
6. Aniridia - ANS-absence of an iris
7. anterior chamber - ANS-the area bounded in front by the cornea and in the back by the
lens and filled with aqueous
8. aqueous - ANS-a clear, watery solution in the anterior and posterior chambers
9. aqueous layer - ANS-layer fo the tear film that contains the nutrients and antibiotic
properties
10. Arcuate Staining - ANS-How tight is this lens edges? check to see if it is properly
blended or finished. send back for further polishing/redgeing. reconsider diameter or
optic zone sizes
11. Crescent shaped stain from improper insertion, rough edge of contact lens or improper
recentering of contact lens
12. artery - ANS-the vessel supplying blood to the eye
13. Basic Tear secretion - ANS-produced by glands of wolfring and glands of krause
14. blepharitis - ANS-inflammation of the glands and eyelash follicles along the margin of the
eyelids
15. Bowman's alyer - ANS-second layer of the cornea, will form scar tissue if damaged
16. bullous keratopathy - ANS-corneal edema with painful blisters in the epithelium due to
corneal endothelial dysfunction
17. canal of schlemm - ANS-the passageway for the aqueous fluid to leave the eye
18. Central Staining - ANS-Common: Corneal Edema
19. Lens material, increase DK or move to a thinner lens design
20. choroid - ANS-carries blood vessels and is the inner coat between the sclera and the
retina
21. ciliary body - ANS-unseen part of the iris, together with the ora serrata form the uveal
tract
22. clear lens replacement - ANS-patients over 40, like cataract removal, remove crystalline
liens and replace with intraocular lens implant
23. coloboma - ANS-conditions where normal tissue in or around the eye is missing at birth
24. conjunctiva - ANS-a clear membrane covering the white of the eye
25. Conjunctivitis - ANS-inflammation of the conjunctiva
, 26. cornea - ANS-a clear transparent portion of the outer coat of the eyeball through which
light passes to the lens
27. Corneal Dystrophy - ANS-group of genetic, often progressive, eye disorders in which
abnormal material often accumulates in the clear (transparent) outer layer of the eye
(cornea).
28. corneal edema - ANS-When water is retained and swelling occurs in the cornea.
29. Corneal Infiltrates & ulcers - ANS-A discrete collection of inflammatory cells in the
cornea
30. corneal scarring - ANS-Superficial grayish opacity on the cornea which is usually the
result of an old injury or infection of the cornea.
31. corneal topography - ANS-Map of the variations of curvature in the cornea; like a
geographical relief map of the cornea
32. A device that records the surface terrain of the cornea, used to detect aberrations of the
contour, as well as regular and irregular astigmatism.
33. crystalline lens - ANS-refraction of 1.42 (12-15 diopters)
34. transparent avascular body between the vitreous and the back of the iris
35. capable of changing its shape from the ciliary muscle
36. Diffuse Illumination - ANS-widest slit w/longest aperture
37. used to view overall areas
38. ocular adnexa, cornea, sclera, lids, conjunctiva, lens surface
39. lens fitting characteristics
40. Diffuse Staining - ANS-Solutions- toxic or allergic reaction?
41. Cleaning or storage changes
42. Dimple Veil - ANS-Not a stain but excessive air bubbles trapped under a lens. Usually a
lens that is too steep or too flat at the edge periphery.
43. Direct Focal Parallepiped Illumination - ANS-creates a 3-D cube
44. used to assess width, depth & height of an object within the cornea
45. scars, infiltrates, staining and lens/cornea relationship
46. endothelium - ANS-5th layer of the cornea. If the eye is deprived of oxygen this layer will
lose cells more quickly and cause swelling
47. entropion - ANS-inward turning of the rim of the eyelid
48. esophoria - ANS-Tendency for the eye to turn inward
49. esotropia - ANS-definite turning of the eye inward
50. exophoria - ANS-Tendency for the eye to turn outward
51. exophthalmus - ANS-s a bulging of the eye anteriorly out of the orbit (can be from
grave's disease)
52. exotropia - ANS-definite turning of the eye outward
53. Extropion - ANS-outward turning of the rim of the eyelid
54. Foreign Body Staining - ANS-foreign body trapped under the lenses. No lens for a day or
2. Evaluate lens for any foreign bodies
55. frontalis muscle - ANS-allows the eyelid to droop or sag
56. Fungal keratitis - ANS-is usually secondary to trauma involving organic material; it can
also be contact lens or solution related
