Insights
Harlequin ichthyosis (HI) can cause severe conjunctival protrusion. Gentle debridement and moisturizing of hyperkeratotic skin improved ocular symptoms in two infants with HI.
Area of Science:
- Ophthalmology
- Genetics
- Neonatology
Background:
- Harlequin ichthyosis (HI) is a rare, severe genetic disorder of the skin.
- HI presents with a generalized hyperkeratotic layer, posing unique challenges for affected infants.
- Ocular complications, including conjunctival protrusion and chemosis, are significant concerns in HI management.
Observation:
- Two infants diagnosed with Harlequin ichthyosis presented with severe conjunctival protrusion and chemosis.
- One infant was diagnosed postnatally, while the other had suspected HI via prenatal ultrasonography.
- Both infants exhibited thickened skin and significant ocular surface abnormalities.
Findings:
- Treatment involved daily application of a vitamin A derivative and gentle debridement of the hyperkeratotic skin.
- Meticulous attention was paid to sterilizing and moisturizing the ocular surface.
- The conjunctival protrusion gradually improved with this conservative management approach.
Implications:
- Increased survival rates in infants with HI necessitate clear guidelines for ocular management.
- Conservative, patient-centered care focusing on skin debridement and ocular surface hydration is crucial.
- Effective management of ocular complications can improve the overall prognosis for infants with Harlequin ichthyosis.
Background:
We present two patients who developed severe protrusion of the conjunctiva and chemosis secondary to Harlequin ichthyosis (HI).
Case Reports:
Case 1 was a male infant diagnosed with HI who had parchment-like appearance and conjunctival protrusion with severe chemosis. Case 2 was a female infant on whom HI had been suspected before birth through ultrasonography. She showed thickened skin over the entire body and conjunctival protrusion with severe chemosis. For both cases, a vitamin A derivative was applied and the hyperkeratotic layer was peeled off every day. Great care was taken to sterilize and moisten the ocular surface. The conjunctival protrusion gradually improved and other systemic conditions were successfully treated. HI is a rare condition, but affected infants are surviving longer than previously and hence guidelines for ocular management are now required.
Conclusions:
Gentle and patient debridement of the hyperkeratotic skin and moisturizing were important in treating the unusual conjunctival protrusion.

Papillary Dermis
The dermis might be considered the "core" of the integumentary system, as distinct from the epidermis and hypodermis. It contains blood and lymph vessels, nerves, and other structures, such as hair follicles and sweat glands. The dermis is made of two layers of connective tissue that comprise an interconnected mesh of elastin and collagenous fibers, produced by fibroblasts.
