What is corneal verticillata?
Disease Entity. Cornea verticillata (also called vortex keratopathy, whorl keratopathy, or Fleischer vortex) describes a whorl-like pattern of golden brown or gray opacities in the corneal epithelium. It is termed cornea verticillata from the Latin noun “verticillus,” meaning “whorl”.
What causes corneal verticillata?
Cornea verticillata is often caused by the use of certain systemic medications, the most common of which include amiodarone, chloroquine, hydroxychloroquine, indomethacin, and phenothiazenes. Cornea verticillata can also be seen in the sphingolipidosis, Fabry disease.
What are corneal deposits?
Corneal verticillata, also called vortex keratopathy, are one type of corneal deposits. Verticillata are readily recognizable by their distinct appearance as fine, golden-brown or gray opacities that are almost always bilateral. The opacities branch out from a central whorl, usually across the inferior cornea.
What drugs cause vortex keratopathy?
Vortex keratopathy is commonly caused by certain cationic amphiphilic drugs such as amiodarone, antimalarials, suramin, tamoxifen, chlorpromazine and non-steroidal anti-inflammatory drugs. These deposits usually occur once a certain dose of the drug is reached.
What is neurotrophic cornea?
Neurotrophic keratitis is a degenerative corneal disease caused by impairment of corneal sensory innervation. It is characterized by decreased or absent corneal sensation, leading to epithelial breakdown, impairment of healing, and ultimately to the development of corneal ulceration, melting and perforation.
What is aniridia of the eye?
Aniridia is a rare condition characterized by abnormal development of the iris of the eye. The iris is the circular, colored part in the middle of the eyeball. The center of the iris is known as the pupil. The iris can control the size of the pupil, which regulates the amount of light that enters the eye.
How does Fabry disease affect the eyes?
How does Fabry disease affect the eyes? Fabry disease can lead to corneal opacities — grey, brown, or yellowish streaks that appear on the cornea, the clear outer layer that covers the lens of the eye. Sometimes, they first appear as a haze or fog over the cornea, becoming more streak-like with time.
What is corneal toxicity?
Corneal toxicity is caused by chemical trauma and by iatrogenic and factitious disease, which are often overlooked, and which are reviewed here. The clinical signs of iatrogenic disease are usually nonspecific and identical to those resulting from other causes of surface disease.
What causes granular corneal dystrophy?
Granular corneal dystrophy is caused by a mutation in the TGFBI gene, located on chromosome 5q31. The disorder is inherited in an autosomal dominant manner.
Does vortex keratopathy affect vision?
Vortex keratopathy is the most common (70–100%) ocular change caused by amiodarone. Although the most common findings are corneal, lens opacities and optic neuropathy have also been reported due to amiodarone. In the current cases, lens changes and retinal changes were not observed.
What medications cause corneal edema?
The use of certain drugs can also increase your risk for corneal edema:
- benzalkonium chloride, a preservative used in many eye drops and anesthetic drugs.
- chlorhexidine (Betasept, Hibiclens), an antiseptic used to disinfect the skin before surgery.
- amantadine (Gocovri), a drug used to treat viruses and Parkinson’s disease.
What is a neurotrophic?
Neurotrophins, a family of closely related proteins, were originally identified as growth factors for survival, development, and function of neurons in both the central and peripheral nervous systems. Subsequently, neurotrophins have been shown to have functions in immune and reproductive systems.
What does it mean to be neurotrophic?
1 : relating to or dependent on the influence of nerves on the nutrition of tissue.
What do you call eyes without pupils?
Aniridia — When There’s No Iris in Your Eye.
When is aniridia diagnosed?
Aniridia occurs while the eye is developing during the 12th to 14th week of pregnancy. In most cases it is due to a mutation in the short arm of chromosome 11 (11p13) and affects the PAX6 gene, however it is also seen in genetic defects in nearby genes as well.
Which drugs produce ocular toxicity?
Many systemic drugs may produce ocular toxicity, including bisphosphonates, topiramate, vigabatrin, isotretinoin and other retinoids, amiodarone, ethambutol, chloroquine and hydroxychloroquine, tamoxifen, quetiapine, cyclo-oxygenase (COX)-2 inhibitors, erectile dysfunction agents and some herbal medications.
Can you go blind with corneal dystrophy?
While corneal dystrophy can cause vision impairment, it rarely leads to complete blindness. The cornea consists of six layers, and deterioration can start in any of them. This leads to swelling (edema) that interferes with normal vision. Think of it like a smudge on a camera’s lens.
