What causes punctate keratopathy?

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.

What does a punctate lesion of the cornea look like?

This problem appears as fine, scattered areas of loss of epithelium from the cornea – the clear part of the surface of the eye. The lesions appear punctate (looking like dots or points) but sometimes can appear dendritic (linear and branching). Superficial punctate keratitis is uncommon and not communicable.

What is punctate epithelial erosions?

Punctate epithelial erosions (PEE) are evidence of ocular surface dryness. They represent areas of epithelial cell loss and therefore stain positively with fluorescein. The distribution of the PEE can provide information regarding the underlying etiology.

Does thygeson’s go away?

Thygeson’s keratitis can take up to 3 years to completely resolve. Typically, his patients have had limited response to corticosteroids, and when the drugs were discontinued, the condition returned, Dr. Freund said.

How is punctate keratitis treated?

Diagnosis is by history, presence of superficial punctate keratitis, and absence of a foreign body or infection. Treatment consists of an antibiotic ointment (eg, bacitracin or gentamicin 0.3% ointment every 8 hours) and occasionally a short-acting cycloplegic drug (eg, cyclopentolate 1% drop every 4 hours).

Where is the location of punctate epithelial erosion?

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.

Can you go blind from SPK?

Keratitis is usually easy to treat and clears up quickly. But if an infection goes deeper than the surface of your cornea, it can leave scars that damage your vision or even cause blindness.

Is thygeson’s an autoimmune disease?

Thygeson’s superficial punctate keratitis (TSPK) is a chronic, bilateral epithelial keratitis. Dr Philips Thygeson first reported TSPK in 1950. Although the etiology of TSPK remains unknown, it has been reported to be associated with viral and autoimmune pathologies.

How do you treat punctate epithelial erosions?

Punctate epithelial erosions may be treated with artificial tears. In some disorders, topical antibiotic is added to the treatment. Patients should discontinue contact lens wear until recovery.

Can you go blind from keratitis?

If you notice any of the signs or symptoms of keratitis, make an appointment to see your doctor right away. Delays in diagnosis and treatment of keratitis can lead to serious complications, including blindness.

How long does it take for inflamed cornea to heal?

Superficial corneal abrasions tend to heal quickly — usually within two or three days. Some corneal abrasions may require an antibiotic ointment that stays on the eye longer, a steroid to decrease inflammation, and something to relieve pain and light sensitivity.

How rare is TSPK?

Although TSPK was originally described as a bilateral process, 32% of patients reported unilateral TSPK, versus 20% in a previous study [1]. However, Nagra et al. [1] reported marked asymmetry in almost half of the patients.
