Amniotic Membrane-Covered Conformer and Fibrin Glue for Toxic Epidermal Necrolysis

Stevens-Johnson syndrome and its more severe form, toxic epidermal necrolysis, are immunologic disorders that cause widespread blistering of the skin and mucous membranes. Its incidence is higher in children and can lead to long-term disabling ocular surface complications that can be averted with amniotic membrane transplantation early in the disease. To introduce an amniotic membrane treatment technique that is time efficient and minimally invasive but still allows for extensive coverage of the ocular mucosal surfaces to prevent and lessen the severity of the complications from ocular surface sequelae.

The procedure was undertaken in the operating room under general anesthesia. Symblephara were divided before an amniotic membrane-covered conformer was placed into the fornices. Fibrin glue was used to secure the conformer and to keep the palpebral aperture closed. Topical chloramphenicol 0.5% and prednisolone 0.5% were prescribed 4 times a day.

After 7 days, the conformers were removed and new amniotic membrane-covered conformers were reapplied in both eyes for a further week. After the second round of treatment, the conformers were left out for 3 days. Inferior symblephara reformed in the left lower fornix, and therefore, a third round of treatment was undertaken in the left eye only, which was then removed after 7 days. A follow-up at 8 weeks revealed 20/20 vision with minimal symblephara in either eye.

This novel technique, using an amniotic membrane-covered conformer in combination with fibrin glue, allows for the coverage of the entire ocular surface and protection of the lid margins while requiring minimal preparation and surgical time. This technique could also be used in patients with other cicatrizing ocular surface conditions, such as chemical or thermal injuries or postreconstructive surgery of the fornices.
