What is Phlyctenular conjunctivitis?
Phlyctenular keratoconjunctivitis is a nodular inflammation of the cornea or conjunctiva that results from a hypersensitivity reaction to a foreign antigen.
What does Phlyctenule mean?
Medical Definition of phlyctenule : a small vesicle or pustule especially : one on the conjunctiva or cornea of the eye.
What is spring catarrh?
Vernal Keratoconjunctivitis (VKC), also known as Spring Catarrh, is a rare but serious allergic disease affecting the eyes of young children, especially boys, who usually have other allergic diseases such as eczema and/or asthma.
What causes Phlyctenular conjunctivitis?
Phlyctenular keratoconjunctivitis is not an infection. It is an immune reaction to bacteria that are on or around the eyes. Some of the bacteria that trigger this disorder are staphylococci, and rarely, tuberculosis, and Chlamydia. This disorder is more common among children.
What causes Symblepharon?
Symblepharon occurs from an abnormal healing process after injury to the conjunctiva. Whatever the inciting injury, the loss of epithelial cells from both the bulbar and palpebral conjunctiva allow an abnormal adhesion to form between the bulbar and palpebral conjunctiva.
What causes Phlyctenular keratoconjunctivitis?
How is Limbitis treated?
Final Treatment and Management: The patient required high-dose topical steroids in the form of Prednisolone q1h OD for resolution of her allergic limbitis. Due to limbal thinning, Prednisolone was eventually replaced with medroxyprogesterone, cyclosporine 1% and serum tears.
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 conjunctivitis an allergy?
Conjunctivitis is an eye condition caused by infection or allergies. It usually gets better in a couple of weeks without treatment.
Is Symblepharon serious?
Symblepharon can lead to a number of complications. The adhesion can encroach on the limbus and grow over the cornea, leading to vision loss. The adhesions can also decrease eye movement, cause diplopia, and prevent the normal functioning of the eyelids through mechanical forces.
How do you prevent Symblepharon?
Symblepharon after acute conjunctival injury can be prevented by separating the raw surfaces for one to two weeks, until re-epithelialization takes place. We have used a soft contact lens and a conjunctival ring without a corneal center, or lined the eyelid and palpebral conjunctiva with plastic.
What is Limbitis eye?
The condition causes inflammation of the surface of the eye. The conjunctiva (the skin covering the eye) can develop tiny lumps, limbitis. In addition, the under surface of the upper lid also becomes inflamed. The eye is very red and itchy to start with.
What are Herbert pits?
Trachoma infection causes follicular conjunctivitis, sometimes involving the cornea and limbus. When infectious follicles heal, they are replaced by rounded, depressed, or flat scars (ie, Herbert pits) as seen in this patient.
What is Stocker’s line?
A Stocker line is the brown iron line in the cornea anterior to the head of the pterygium.
Does conjunctivitis cause pain?
Because the conjunctiva (unlike the cornea, which covers the iris and pupil) is not very sensitive, conjunctivitis is usually uncomfortable rather than painful. The main symptom of infective conjunctivitis is ‘pink eye’.
