This continuing education course is joint-sponsored by the Pennsylvania College of Optometry. Steroid medications have presented a special set of challenges to the profession of optometry as it has attained therapeutic privileges.
Opponents of our expanded therapeutic drug prescribing have cited potential harm to an unwary public. In addition, optometric education of decades past had over-emphasized the negatives of steroids, and proposed too-narrow indication for their usage. However, when properly prescribed, topical steroids provide tremendous benefits, such as controlling inflammation and scarring, preventing vision loss, limiting lost productivity at work or school, and enabling a more rapid return to comfortable contact lens wear.
Steroids are safe and effective as long as the doctor understands the risks and knows what to do in the event of a steroid induced event. This article encourages proper topical steroid usage while minimizing the risk of adverse reactions. Topical ophthalmic steroids are categorized as synthetic glucocorticoids, meaning that they are manufactured to mimic the effects of their naturally-occurring counterpart known as cortisol. Cortisol suppresses the release of substances in the body that cause inflammation.
It also increases blood sugar through gluconeogenesis, and it aids in the metabolism of fat, protein and carbohydrate. However, steroids are not without risk, as doctor and patient need to be acutely aware of steroid use as an etiology in glaucoma, cataracts and the potentiation of infection, especially in longer treatment periods. Cataract is also a concern with prolonged use of steroids. Unfortunately, this irreversible result is due to alteration of crystalline lens metabolism.
Also, because steroids are immunosuppressive, they can limit the white blood cell response that would normally fight off infection. So, herpes simplex and fungal infection are especially worrisome when steroid use is prolonged. Thus, the key to proper steroid use is weighing the risk vs. Close monitoring in follow-up care allows for risks to be moderated with proper dosage tapering, as well as alternate therapies if adverse effects occur.
Soft steroids should have a place in any primary care optometric practice. These allow us longer tapering schedules, which are safer, as well as milder immunosuppression and fewer steroid side effects. While stronger topical agents—prednisolone, dexamethasone and difluprednate—are indicated for severe and acute inflammation, they lack the safety profile for most cases of chronic therapy.
Diverse external diseases, ranging from herpes zoster to silicone hydrogel-associated inflammation, have an ongoing antigenicity that may require a month or more of immunosuppression. So, although the stronger agents may be required initially, the softer steroids provide a safer opportunity to taper the anti-inflammatory effect with less likelihood of inducing secondary glaucoma or cataract.
This condition is primarily noninfectious, and can be managed confidently at the primary care level in the majority of cases. However, steroid fears can lead the practitioner to under-prescribe these agents, and actually cause a prolonged treatment period that increases the total steroid dosage. Unfortunately, sometimes patients are started on a q. While this may be driven by the fear of steroid-induced side effects, it actually increases the likelihood that the drug will have to be used for a longer period of time.
Starting the patient on hourly dosing, with tapering over the course of a month or more, seems to avoid prolonged treatment periods in most cases of anterior uveitis. In our practice, we seldom treat anterior uveitis at an initial dosage of less than every two hours, with an hourly dosage being most common.
Severe cases are treated with an initial dosage of one drop every 15 minutes for the first hour, and hourly thereafter, for one week.
If this schedule is not maintained, we find that the patient becomes more vulnerable to a relapse of signs and symptoms, thus requiring a restarting of the treatment regimen. The result is that the total steroid use is much greater, and presents unnecessary safety risks. We now have a new topical steroid option with the release of Durezol difluprednate 0.
This drug has demonstrated therapeutic equivalence to topical prednisone in treating uveitis, with a dosing schedule that is cut in half. Because we know that compliance decreases as prescribed dosage increases, we can likely attain better results with lesser dosing.
However, this drug has not eliminated concerns of cataract and steroid-induced glaucoma and its IOP elevation may be comparatively higher than with other steroids. Close follow-up is essential, and the clinician must be prepared to prescribe medications to lower intraocular pressure if ongoing steroid therapy is required. While follow-up is geared towards the severity of the underlying condition, we monitor IOP weekly if steroid use approaches a month or more. Topical steroids should be avoided in seasonal and perennial allergic conjunctivitis, if possible, because they can dig the practitioner a deep hole in terms of chronic use.
However, there are occasions when steroid use is justified. If discomfort persists to such a degree that it limits school or job performance, the practitioner is obligated to provide safe yet rapid relief. Modern mast cell stabilizers and antihistamines are extremely effective, but may not offer symptomatic relief for the first several days of use.
Work and school performance may be limited by allergy symptoms, to such an extent that a steroid prescription is indicated. Similarly, contact lens wear can be interrupted by allergy, which can be devastating to keratoconus and higher refractive error patients.
The duration of allergy treatment with steroid drops seldom needs to exceed two weeks. These drugs will provide continued relief of allergy signs and symptoms once the steroids are discontinued.
Patient management must include discussion of the risks and benefits of steroid treatments, with emphasis on short-term treatment. If antigens are persistent enough in their presentation, eosinophil recruitment can result. This infiltration into ocular tissue alters the inflammatory chemistry, which limits the effectiveness of mast cell stabilizers and antihistamines. Eosinophilia may contribute to scarring of lid, cornea and conjunctiva, so prevention may require steroid use.
The practitioner may use conjunctival scrapings or other cytologic methods, but the clinical appearance of the eye can be the key indicator. We find that hypertrophy and dermatitis of the lid skin, paired with the chronicity of the response, can indicate that cellular elements are involved, and that steroids are indicated. This type of lid inflammation, if left uncontrolled, can lead to fibrosis and scarring, which can alter cosmetic appearance and decrease lid function.
Fluorometholone and loteprednol are ideal agents if steroid treatment is required, because their propensity to elevate intraocular pressure is low. This generally non-infectious entity is a common presentation that benefits from steroid as well as antibiotic therapy.
In general, lens cessation and subsequent refitting are primary treatments. However, antibiotic coverage is wise if there is suspicion of an excessive bacterial load.
It is important to differentiate inflammation from true infection in contact lens-associated infiltrative events. Pain, hyperacute redness, anterior chamber reaction, and excavation of the corneal epithelium in lesions larger than 2mm should raise suspicion of microbial keratitis. But, more commonly, patients present with smaller infiltrates, singly or in multiples, that have bacteria as only a minor player. Is It an Ulcer or an Infiltrate? More problematic is the ongoing inflammatory response, which may far outlast the infectious phase, and make restarting or refitting of lens wear quite difficult.
Topical ocular steroids are often better utilized if they are not combined with antibiotic preparations. Tobramycin has strong antibiotic properties, especially against gram-negative bacteria, but tends to be toxic to the healing corneal epithelium.
Fluoroquinolone antibiotics have less toxicity and are better tolerated. Although there are asymptomatic cases of infiltrative keratitis, many patients are troubled by discomfort, blurred vision and redness.
Typical treatment of infiltrative keratitis is to initiate antibiotic therapy with a fluoroquinolone, one drop in the affected eye, four times daily for one week. Follow-up examination in four or five days provides critical information about whether to restart contact lens wear, and when to taper the steroid drops.
Significant corneal staining or persistent infiltrates can indicate that contact lens wear is a week or more away. Consultation with a cornea specialist is recommended if signs and symptoms persist.
We often see infiltrative keratitis patients who have been treated with antibiotic therapy alone. The consequence here is that ultimate resolution is delayed. Interestingly, research done in the development of Restasis cyclosporine, Allergan for dry eye has revealed that inflammatory white blood cells can have a life expectancy of days or more. It is imperative to use the immunosuppressive benefits of steroids with a slow taper as contact lens wear is resumed, or the patient will suffer setbacks and require multiple office visits.
We typically restart limited contact lens wear when the rehabilitating cornea can tolerate a limited steroid dosage of once to twice daily. Both contact lens wearers and non-wearers alike can suffer from this relatively mild and treatable condition. Patients present with mild to moderate redness and discomfort, with an approximately 1mm peripheral corneal infiltrate being the significant slit lamp finding. Antibiotic therapy is helpful, though the infectious component of this disorder is easy to eradicate.
The question is whether and when steroid use is appropriate. We make two assessments: First, what is the risk of more serious infection, as indicated by the appearance of the corneal lesion? Small, non-ulcerated lesions in the corneal periphery generally have very low risk of progression to more serious and sightthreatening infection.
Second, what is the level of patient discomfort, in terms of his or her ability to function at work or school? Though marginal keratitis does not usually cause extreme pain, it may be enough to disrupt daily routines of some patients. Failure to initiate steroid treatment may expose the patient to unnecessary discomfort and loss of productivity.
If there is uncertainty, prescribe an antibiotic initially and then follow up in a day or two to assess whether to add a separate steroid. Posterior blepharitis, also known as meibomian gland dysfunction, is primarily an inflammatory disease. While antibiotic therapy is helpful in reducing lid flora, patients do not attain comfort until lid inflammation is reduced. Steroid therapy remains the best method to attain rapid patient comfort. A classic approach has been to apply topical combination drugs, such as TobraDex or Zylet.
The recently-launched TobraDex ST tobramycin 0. A greater therapeutic effect is often the result, though steroid concerns should limit treatment periods to one week.
Because posterior blepharitis tends to be a recurrent and chronic condition, exercise great caution in limiting steroid use, especially for dexamethasone or prednisolone.
