Eye: Diagnostic Terms

  1. refractive errors
    defects in the bending of light as it enters the eye, causing an improper focus on the retina
  2. astigmatism
    distorted vision caused by an oblong or cylindrical curvature of the lens or cornea that prevents light rays from coming to a single focus on the retina
  3. hyperopia
    farsightedness; difficulty seeing close objects when light rays extend beyond the proper focus on the retina
  4. myopia
    nearsightedness; difficulty seeing distant objects when light rays fall short of the proper focus on the retina
  5. presbyopia
    impaired vision owing to old-age loss of accommodation
  6. accommodation
    ability of the eye to adjust focus on near objects
  7. amblyopia
    decreased vision in early life due to functional defect that can occur as a result of strabismus, refractive errors, or trauma; usually occurs in one eye, also known as lazy eye
  8. aphakia
    absence of the lens, usually after cataract extraction
  9. blepharitis
    inflammation of the eyelid
  10. blepharochalasis/dermatochalasis
    baggy eyelid; overabundance and loss of elasticity of skin on the upper eyelid, causing a fold of skin to hang down over the edge of the eyelid when the eyes are open
  11. blepharoptosis/ptosis
    drooping of the eyelid usually caused by paralysis
  12. chalazion
    chronic nodular inflammation of a meibomian gland, usually the result of a blocked duct; commonly presents as a swelling on the upper or lower eyelid
  13. cataract
    opaque clouding of the lens causing decreased vision
  14. conjunctivitis
    pinkeye; inflammation of the conjunctiva
  15. dacryoadentitis
    inflammation of the lacrimal gland
  16. dacryocystitis
    inflammation of the tear sac
  17. diabetic retinopathy
    disease of the retina in diabetics characterized by capillary leakage, bleeding, and new vessel formation, leading to scarring and loss of vision
  18. ectropion
    outward turning of the rim of the eyelid
  19. entropion
    inward turning of the rim of the eyelid
  20. epiphora
    abnormal overflow of tears caused by blockage of the lacrimal duct
  21. glaucoma
    group of diseases of the eye characterized by increased intraocular pressure that results in damage to the optic nerve, producing defects in vision
  22. hordeolum
    sty; an acute infection of a sebaceous gland of the eyelid
  23. iritis
    inflammation of the iris
  24. keratitis
    inflammation of the cornea
  25. macular degeneration
    breakdown or thinning of the tissues in the macula, resulting in partial or complete loss of central vision
  26. pseudophakia
    eye in which the natural lens of is replaced with an artificial lens implant
  27. pterygium
    fibrous growth of conjunctival tissue that extends onto the cornea
  28. retinal detachment
    separation of the retina from the underlying epithelium, disrupting vision and resulting in blindness if not repaired surgically
  29. retinitis
    inflammation of the retina
  30. strabismus
    crossed eyes; a condition of eye misalignment caused by intraocular muscle imbalance
  31. esotropia
    right or left eye deviates inward toward the nose
  32. exotropia
    right or left eye deviates outward away from the nose
  33. scleritis
    inflammation of the sclera
  34. trichiasis
    misdirected eyelashes that rub on the conjuctiva or cornea
