Chorioretinal disorders in diseases classified elsewhere

H33 Retinal detachments and breaks

Other retinal disorders

GLAUCOMA

 

DISORDERS OF VITREOUS BODY AND GLOBE

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

DISORDERS OF OPTIC NERVE AND VISUAL PATHWAYS

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

VISUAL DISTURBANCES AND BLINDNESS

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