• Keratoconus
  • It is used to perform corneal pachymetry prior to refractive surgery, for Keratoconus screening, LRI surgery and is useful in screening for patients suspected of developing glaucoma among other uses. (wikipedia.org)
  • reduce corneal
  • Other, albeit less frequent, potential causes of the disease are: intracranial space-occupying lesions such as neuroma, meningioma and aneurysms, which may compress the trigeminal nerve and reduce corneal sensitivity. (wikipedia.org)
  • LRI is used to reduce corneal astigmatism by placing a pair of incisions of a particular depth and arc length at a steep axis of corneal astigmatism. (wikipedia.org)
  • Astigmatism
  • Does Blunt Ocular Trauma Induce Corneal Astigmatism? (lww.com)
  • Corneal damage can result in inflammation, scarring, loss of surface smoothness, irregular astigmatism, and loss of optical clarity. (medscape.com)
  • surface
  • If the fluorescein strip turns pale upon application to the corneal surface, the person tests positive for the corneal deformity he/ she is being tested for. (wikipedia.org)
  • pachymetry
  • Corneal pachymetry is essential for other corneal surgeries such as Limbal Relaxing Incisions. (wikipedia.org)
  • Corneal pachymetry is also considered an important test in the early detection of glaucoma. (wikipedia.org)
  • As a result of this study and others that followed, corneal pachymetry is now widely used by both glaucoma researchers and glaucoma specialists to better diagnose and detect early cases. (wikipedia.org)
  • nerve
  • Corneal ulcers are painful due to nerve exposure, and can cause tearing, squinting, and pawing at the eye. (wikipedia.org)
  • Most corneal nerve fibres are sensory in origin and are derived from the ophthalmic branch of the trigeminal nerve. (wikipedia.org)
  • contact lenses
  • Patients wearing contacts dont report increased problems with glare and contrast sensitivity, but it is not clear if this is due to the corneal disease, or the contact lenses themselves. (wikipedia.org)
  • diagnosis
  • A definitive diagnosis is established only after a positive culture report (lactophenol cotton blue, calcoflour medium), typically taking a week, from the corneal scraping. (wikipedia.org)
