List of eye diseases and disorders

Jump to: navigation, search

This is a partial list of human eye diseases and disorders.

The World Health Organization publishes a classification of known diseases and injuries called the International Statistical Classification of Diseases and Related Health Problems or ICD-10. This list uses that classification.

H00-H59 Diseases of the eye and adnexa

H00-H06 Disorders of eyelid, lacrimal system and orbit

H10-H13 Disorders of conjunctiva

  • (H10) Conjunctivitis — inflammation of the conjunctiva
  • (H11.0) Pterygium — benign growth of the conjunctiva
  • (H11.3) Subconjunctival hemorrhage — burst blood vessels on conjunctiva
  • (H13.1*) Conjunctivitis in infectious and parasitic diseases classified elsewhere
    • Conjunctivitis (due to):
      • Acanthamoeba B60.1+ )
      • adenoviral follicular (acute) ( B30.1+ )
      • chlamydial ( A74.0+ )
      • diphtheritic ( A36.8+ )
      • gonococcal ( A54.3+ )
      • haemorrhagic (acute)(epidemic) ( B30.3+ )
      • herpesviral [herpes simplex] ( B00.5+ )
      • meningococcal ( A39.8+ )
      • Newcastle ( B30.8+ )
      • zoster ( B02.3+ )

H15-H22 Disorders of sclera, cornea, iris and ciliary body

H25-H28 Disorders of lens

  • (H25-H26) Cataract — the lens becomes opaque

H30-H36 Disorders of choroid and retina

  • (H33) Retinal detachment — the retina detaches from the choroid, leading to blurred and distorted vision
  • (H33.1) Retinoschisis — the retina separates into several layers and may detach
  • (H35.0) Hypertensive retinopathy — burst blood vessels, due to long-term high blood pressure
    • (H35.0/E10-E14) Diabetic retinopathy damage to the retina caused by complications of diabetes mellitus, which could eventually lead to blindness
  • (H35.0-H35.2) Retinopathy — general term referring to non-inflammatory damage to the retina
  • (H35.1) Retinopathy of prematurity — scarring and retinal detachment in premature babies
  • (H35.3) Age-related macular degeneration — the photosensitive cells in the macula malfunction and over time cease to work
  • (H35.3) Macular degeneration — loss of central vision, due to macular degeneration
  • (H35.5) Retinitis pigmentosa — genetic disorder; tunnel vision preceded by night-blindness
  • (H35.81) Macular edema — distorted central vision, due to a swollen macula

H40-H42 Glaucoma

  • (H40-H42) Glaucoma — optic neuropathy

H43-H45 Disorders of vitreous body and globe

  • (H43.9) Floaters — shadow-like shapes which appear singly or together with several others in the field of vision

H46-H48 Disorders of optic nerve and visual pathways

H49-H52 Disorders of ocular muscles, binocular movement, accommodation and refraction

  • (H49-H50) Strabismus (Crossed eye/Wandering eye/Walleye) — the eyes do not point in the same direction
  • H52 Disorders of refraction and accommodation
    • (H52.0) Hyperopia (Farsightedness) — the inability to focus on near objects (and in extreme cases, any objects)
    • (H52.1) Myopia (Nearsightedness) — distant objects appear blurred
    • (H52.2) Astigmatism — the cornea or the lens of the eye is not perfectly spherical, resulting in different focal points in different planes
    • (H52.3) Anisometropia — the lenses of the two eyes have different focal lengths
    • (H52.4) Presbyopia — a condition that occurs with growing age and results in the inability to focus on close objects
    • (H52.5) Disorders of accommodation

H53-H54.9 Visual disturbances and blindness

  • (H53.0) Amblyopia (lazy eye) — poor or blurry vision due to either no transmission or poor transmission of the visual image to the brain
  • (H53.0) Leber's congenital amaurosis — genetic disorder; appears at birth, characterised by sluggish or no pupillary responses
  • (H53.1, H53.4) Scotoma (blind spot) — an area impairment of vision surrounded by a field of relatively well-preserved vision
  • (H53.5) Color blindness — the inability to perceive differences between some or all colors that other people can distinguish
  • (H53.6) Nyctalopia (Nightblindness) — a condition making it difficult or impossible to see in the dark
  • (H54) Blindness — the brain does not receive optical information, through various causes
    • (H54/B73) River blindness — blindness caused by long-term infection by a parasitic worm (rare in western societies)
    • (H54.9) micro-opthalmia/coloboma — a disconnection between the optic nerve and the brain and/or spinal cord.

H55-H59 Other disorders of eye and adnexa

  • (H57.9) Red eyeconjunctiva appears red typically due to illness or injury
  • (H58.0) Argyll Robertson pupil — small, unequal, irregularly shaped pupils

Other codes

  • (B36.1) Keratomycosis — fungal infection of the cornea
  • (E50.6-E50.7) Xerophthalmia — dry eyes, caused by vitamin A deficiency
  • (Q13.1) Aniridia — a rare congenital eye condition leading to underdevelopment or even absence of the iris of the eye
