ASHEVILLE, N.C. – The, according to one of several clinical messages from a pediatric ophthalmologist who spoke at the annual meeting of the Society for Pediatric Dermatology.
“There is a lot of steroid fear out there, which you can argue is actually harmful in itself, because not treating periorbital eczema is related to a lot of eye problems, including chronic discomfort and the eye rubbing that can cause corneal abrasions and keratoconus,” said Sara Grace, MD, a pediatric ophthalmologist who is on the clinical staff at Duke University, Durham, N.C. She maintains a practice at North Carolina Eye, Ear, Nose, and Throat in Durham.
Although the risks of periorbital steroid absorption are real, a limited course of low potency topical steroids is generally adequate for common periorbital indications, and these appear to be safe.
“There is insufficient evidence to link weak periocular topical corticosteroids such as desonide or hydrocortisone with ocular complications,” said Dr. Grace, suggesting that pediatric dermatologists can be reassured when using these medications at low concentrations.
“Potent periocular steroids have been associated with ocular complications, but this has typically involved exposures over months to years,” Dr. Grace specified.
When topical corticosteroids are applied at high concentrations on the face away from the periorbital area, glaucoma and other feared ophthalmic complications cannot be entirely ruled out, but, again, the risk is low in the absence of “very large quantities” of potent topical agents applied for lengthy periods of time, according to Dr. Grace, basing this observation on case studies.
In children, as in adults, the potential exception is a child with existing ocular disease. In such cases, or in children with risk factors for ocular disease, Dr. Grace recommends referral to an ophthalmologist for a baseline examination prior to a course of topical corticosteroids with the potential of periocular absorption. With a baseline assessment, adverse effects are more easily documented if exposure is prolonged.
The message, although not identical, is similar for use of dupilumab (Dupixent) or other biologics that target the interleukin-13 (IL-13) pathway. The potential for complications cannot be ignored but these are often time-limited and the benefit is likely to exceed the risk in children who have severe atopic dermatitis or other skin conditions for which these treatments are effective.
There are several potential mechanisms by which biologics targeting IL-13 might increase risk of ocular complications, one of which is the role that IL-13 plays in ocular mucus production, regulation of conjunctival goblet cells, and tear production, according to several published reports.
“Up to 30% of children will get some type of eye complication but, fortunately, most of them will not have to stop therapy,” Dr. Grace said. These side effects include conjunctivitis, blepharitis, keratitis, dry eye, and itching, but they are typically manageable. Topical steroids or calcineurin inhibitors can be offered if needed, but many of these conditions will self-resolve. Dr. Grace estimated that less than 1% of patients need to stop treatment because of ophthalmic side effects.
