How is vernal keratoconjunctivitis treated?
Treatment may include: Antihistamine or anti-inflammatory drops that are placed into the eye. Eye drops that prevent a type of white blood cell called mast cells from releasing histamine (may help prevent future attacks) Mild steroids that are applied directly to the surface of the eye (for severe reactions)
What are Trantas dots?
Peri-limbal Horner-Trantas dots are focal white limbal dots consisting of degenerated epithelial cells and eosinophils. Limbal disease can result in a limbal stem cell deficiency which can lead to pannus formation with corneal neovascularization. Corneal signs vary according to the severity of the disease process.
Is vernal keratoconjunctivitis curable?
Vernal keratoconjunctivitis (VKC) generally resolves spontaneously after puberty without any further symptoms or visual complications. However, the development of corneal ulcers (in approximately 9.7% of affected individuals), cataract or glaucoma can potentially cause permanent vision loss.
How long does vernal keratoconjunctivitis last?
While it is considered a long-term disease with an average duration of 4–8 years, VKC generally subsides before or just after puberty [1, 2, 4]. It can persist or reactivate after puberty, however, a VKC-like disease has been found in young adults without any history of allergic disease in childhood [9].
Is vernal conjunctivitis serious?
An aggressive form of allergic conjunctivitis is vernal conjunctivitis in children and atopic conjunctivitis in adults. Vernal disease is often associated with shield corneal ulcers.
Does prednisone help with pink eye?
Results: Topical corticosteroids are useful in treating ocular inflammation, but most treatment guidelines recommend steroid use generally in severe cases of conjunctivitis. This is partly due to risks associated with steroid use.
How common is vernal keratoconjunctivitis?
One survey suggests VKC may have a prevalence rate of 3.2 per 10,000 individuals in Western Europe. Another study involving over 400 affected individuals only in an area of Northern Italy reported that the average incidence independent of gender and age was 1 in 100,000 new cases.
How long does vernal conjunctivitis last?
What are the white dots in Horner Trantas?
The characteristic Horner-Trantas dots are white dots of eosinophils and epithelial debris. There is corneal involvement in half of cases that range from punctuate epithelial keratitis to superficial pannus to corneal shield (Togby’s) ulcers. Corneal ulcers are observed in 10% of patients.
What are Horner-Trantas dots in vernal keratoconjunctivitis?
Figure 3. Horner-Trantas dots in vernal keratoconjunctivitis. American Academy of Ophthalmology. The cornea may become involved in VKC, and the corneal changes range from mild (punctate epithelial erosions) to severe (macroerosions and ulcers).
What kind of tissue is Horner Trantas made of?
The limbal form is less common and marked by a broad, thickened, opacification of the superior limbus. The tissue is composed of lymphocytes, plasma cells, macrophages, basophils and a high level of eosinophils. The characteristic Horner-Trantas dots are white dots of eosinophils and epithelial debris.
