2022年8月29日 · What is superficial punctate keratitis? Superficial punctate keratitis (SPK) is damage to the cells of the cornea ’s outer layer. SPK can be visualized by staining the eye with a dye and looking under high magnification and a bright light. It is caused by many conditions and results in discomfort, redness and watery eyes.

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.

Described in 1950 by Phillips Thygeson in a case report series, Thygeson's superficial punctate keratitis (TSPK) is an insidious, chronic and recurrent disorder, characterized by small and elevated oval corneal intraepithelial, whitish-gray opacities, extending to the entire anterior surface of the cornea of both eyes.

2018年12月1日 · S uperficial punctate keratopathy (SPK) appears as irregularities in the squamous epithelium of the cornea that stain with NaFl or Rose Bengal. The staining can range from individual, tiny dots located diffusely over the surface of the cornea to more confluent arrangements of staining in specific patterns.

During this period, we have observed a corresponding increase in ocular irritation and dryness among regular mask users. This finding has not been previously described in the literature but has important implications on eye health and infection prevention, as mask use is likely to continue for the foreseeable future.

There have been reported ocular surface complications due to the face mask wear such as dry eyes, recurrent erosion syndrome or microbial keratitis [1], [2], [3], [4]. Infective keratitis are serious ocular conditions that can lead to corneal opacity, visual impairment, and blindness.

2024年5月13日 · Answer: Superficial punctate keratitis (SPK) is the characteristic finding in Thygeson's Disease where the upper layers of the cornea are inflamed. An ophthalmologist may see small white opacities just below the surface of the cornea with a characteristic "negative fluorescein staining" pattern.

2024年4月20日 · Superficial punctate keratitis is a condition that affects the surface of the eye, causing discomfort and vision problems. This article provides an overview of the causes, symptoms, and treatment options for superficial punctate keratitis. It explains how the condition is diagnosed and managed, and offers tips for preventing its recurrence.

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.

Evidence supports that the use of face masks causes an increase in dry eye disease symptoms, a decreased tear break-up time, corneal epithelial trauma, periocular temperature changes and inflammatory markers secretion.
