How is superficial 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).
How do you treat a corneal stain?
Treatment options may include:
- removal of the foreign object from your eye.
- using prescription eye drops or ointment, usually an antibiotic to prevent an infection from developing.
- using over-the-counter lubrication tear drops.
- wearing a temporary eye patch or bandage contact lens.
How long does SPK take to heal?

Does Ortho K really work?
Ortho-K is used to treat and sometimes even eliminate conditions such as myopia, hyperopia and astigmatism. It is appropriate for all ages. In fact, today, this treatment is one of the most effective methods of slowing down progressive myopia in children.
What is punctate staining?
Punctate staining is an important sign of dry eye disease and ocular surface irritation. These fluorescent spots have been considered toxic,72–74 infiltrative, and even infectious events.
How long does superficial punctate keratitis last?
Symptoms of Superficial Punctate Keratitis When ultraviolet light causes the disorder, symptoms usually do not occur until several hours after exposure, and they last for 1 to 2 days.
Does corneal staining go away?
Light staining (less than grade 2) can recover within a few hours, and certainly overnight, assuming that lens wear has ceased. The foreign body track depicted in Figure 16.17 completely resolved in 24 hours. More severe cases of corneal staining (greater than grade 2) may take up to 4 or 5 days to disappear.
Can you go blind from SPK?
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.
Why is Ortho-K bad?
Many people have found ortho-K to be a great treatment since they are not interested in surgical procedures like LASIK. There are risks, including infection, hypoxia, scarring, and other problems, but these are usually the same as those associated with regular, daily wear of soft contact lenses.
Is Ortho-K expensive?
Ortho-k prices in the U.S. generally range from $1,000 to $2,000 (for both eyes), making the procedure about half the cost of LASIK. But particularly difficult cases of ortho-k can cost as much as $4,000.
What causes corneal staining?
There are a large number of reasons for corneal staining caused by lens wear including hypoxia, deposits, care products, lens fit, lens surface or edge irregularities, foreign bodies, and tear film disruption. The integrity of the epithelium should be assessed carefully at each contact lens aftercare visit.
How is superficial punctate keratitis diagnosed and treated?
Doctors diagnose superficial punctate keratitis based on the person’s symptoms and the results of an eye examination. Most people recover fully. Symptoms can often be relieved with eye drops or ointments. Introduction to Corneal Disorders The cornea is the clear layer in front of the iris and pupil.
Is the superficial punctate staining of the corneal harmful?
The literature reflects that superficial punctate corneal staining does not reflect corneal injury or toxicity. More work is required to elucidate the various mechanisms underlying superficial punctate staining, and to provide clinicians with a rational interpretation algorithm for this observation. you can request a copy directly from the author.
Are there any studies on corneal staining in eyes?
Jiang et al 58 reported corneal staining in 45% of eyes in their 54 subjects with orthokeratology lens wear, but did not report the severity of the staining. They suggested that inadequate or unstable tears possibly led to high incidence and recurrent corneal staining.
What are tiny dots on the surface of the cornea?
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.
