Lagophthalmos may develop, exposure keratitis occurs because of drying of the cornea, making it susceptible to minor trauma, and may result in corneal ulceration, vascularization, and corneal scarring. References 1. Williams ML, Elias PM. [ijdvl.com]

Chemosis
There was severe right upper eyelid ectropion, conjunctival injection, chemosis, a subconjunctival mass on the temporal bulbar conjunctiva spontaneously draining pus and corneal haze. The anterior chamber, iris, lens and fundus appeared normal. [ncbi.nlm.nih.gov]
There was marked ectropion of the upper eyelids, with mild conjunctival chemosis, bilateral absence of the eyebrows and eyelashes [Figure 1]. The lids were separated gently with a lid retractor. [ojoonline.org]

Prognosis
Microbial keratitis in patients with lamellar ichthyosis has a poor prognosis. [ncbi.nlm.nih.gov]
Prognosis Prognosis is variable. During the neonatal period, there is a risk of sepsis and hydro-electrolytic troubles. The disease often remains stable over the life, with periods of exacerbation. The life expectancy is normal. [orpha.net]

Pathophysiology
Pathophysiology Patients with lamellar ichthyosis have accelerated epidermal turnover with proliferative hyperkeratosis, in contrast to retention hyperkeratosis. This involves a mutation in the gene for transglutaminase 1 ( TGM1 ). [emedicine.medscape.com]

Prevention
This report reviews the literature on the surgical management of this condition and suggests several modifications to prevent recurrence. [ncbi.nlm.nih.gov]
Self-care measures, including daily bathing, exfoliation of skin, and moisturizing, are imperative in keeping the condition under control and preventing complications, as it prevents build up of skin cells and the attendant symptoms. [ozarkderm.com]
Moisturizers Prevention of overheating Eye drops (to prevent the eyes from becoming dried out) Systemic Retinoids ( isotretinoin and acitretin are very effective, but careful monitoring for toxicity is required. [en.wikipedia.org]
Overheating – Severe scaling of the skin prevents normal sweating so hot weather or vigorous exercise can cause problems. [ichthyosis.org.uk]
