What is superficial punctate keratitis?

Superficial punctate keratitis is an eye disorder caused by death of small groups of cells on the surface of the cornea (the clear layer in front of the iris and pupil). The eyes become red, watery, and sensitive to light, and vision may decrease somewhat. Doctors diagnose superficial punctate keratitis based on the person’s symptoms and

What is the pathophysiology of keratitis?

Keratitis is the inflammation of the cornea and is characterized by corneal edema, infiltration of inflammatory cells, and ciliary congestion. It is associated with both infectious and non-infectious diseases, which may be systemic or localized to the ocular surface.

What is Onchocerca volvulus keratitis?

Onchocerca volvulus keratitis: This results in sclerosing keratitis. Corneal opacity starts from the periphery, and the visual axis gets affected at last. Deep vascularization is noted 360 degrees.

What are the virulent organisms that cause keratitis?

Neisseria meningitides, N. gonorrhea, Corynebacterium diphtheria, Haemophilus influenzae, and Listeria species are the virulent organisms with the potential to penetrate even intact epithelium and cause keratitis. [1] This article talks about the etiology and available current and future management options of different types of keratitis.

Superficial Punctate Keratitis. Superficial punctate keratitis is corneal inflammation of diverse causes characterized by scattered, fine, punctate corneal epithelial loss or damage. Symptoms are redness, lacrimation, photophobia, and slightly decreased vision. Diagnosis is by slit-lamp examination. Treatment depends on the cause.

What is the difference between coarse Pek and superficial punctate keratopathy?

of superficial punctate keratopathy may be found in the eyelids. Blepharitis is commonly associated with this entity. Coarse PEK is seen in far fewer conditions. Viral infections, particularly adenovirus, constitute the vast majority of these. Included in the differential diagnosis of coarse PEK in

What are the stages of punctate epithelial keratopathy?

Stage 111, deep punctate epithelial keratopathy with anterior stromal component. (E) Stage IV, anterior stromal infiltrate. (F) Stage V, anterior stromal infiltrate with overlying epithelial granularity. Modified from Jones6’ 304 AUSTRALIAN JOURNAL OF OPHTHALMOLOGY Figure 3: Thygeson’s superficial punctate keratitis.

What is epithelial keratopathy?

epithelial keratopathy. Coarse lesions, which are usually large enough to be seen with the naked eye, may be epithelial, stromal, or a combination of both. Superficial punctate lesions of the cornea can

What are the characteristics of superficial punctate lesions of the cornea?

Superficial punctate lesions of the cornea can be classified by their morphological features. The two most important characteristics are the PATTERNS OF SUPERFICIAL KERATOPATHY tissues involved and the size of the lesions. Included among these are:

What is Thygeson’s superficial punctate keratitis (SPK)?

cause punctate keratitis of the superficial cornea, Jonesi2 has recommended the term “Thygeson’s superficial punctate keratitis” for the condition originally described by Thygeson, and this has received worldwide acceptance. Thygeson’s superficial punctate keratitis (SPK) is a disease that is peculiar in its lack of associated signs.

Superficial punctate keratitis is corneal inflammation of diverse causes characterized by scattered, fine, punctate corneal epithelial loss or damage. Symptoms are redness, lacrimation, photophobia, and slightly decreased vision.

What causes punctate epithelial erosions on the superior cornea?

In mild disease there may be punctate epithelial erosions on the superior and central cornea. If there is active palpebral disease, mucus may be deposited on the superior corneal epithelium (Fig. 15.23 ), which can stimulate the formation of superficial corneal neovascularization.

How do you check for punctate epithelial erosions in the eye?

Each cornea is examined at the slit lamp using the cobalt blue filter. Punctate epithelial erosions (PEEs) that stain with fluorescein are counted and scored. If there is no PEE, the score is 0.

What is epidemic keratoconjunctivitis (EKC)?

Epidemic keratoconjunctivitis (EKC) is a combined epithelial and subepithelial punctate keratitis most commonly caused by adenovirus type 8. The evanescent subepithelial opacities, unlike the fine or medium-sized ones with adenoviruses types 3, 4, and 7, tend to be like a cluster of coarse, tiny breadcrumbs.
