INTENSE PULSED LIGHT AS A NEW TREATMENT FOR BLEPHAROKERATOCONJUNCTIVITIS: A CASE REPORT

Аннотация

Blepharokeratoconjunctivitis (BKC) refers to a series of conjunctival and corneal disease secondary to blepharitis. Intense pulsed light (IPL) devices contain high-intensity light sources, which emit polychromatic light from 515 nm to 1200 nm. We report the effect of IPL in three cases of BKC.The first case presented eyelid congestion; crusting and scaling at the eyelash root; meibomian gland obstruction and conjuncti-val hyperemia in both eyes. The left eye presented old central corneal scarring with neovascularization. BKC was diagnosed. The male patient was treated with three times of IPL and traditional treatment. The second case presented scaling and sleeve-form crusting at the eyelash root; meibomian gland arranged irregularly with opening obstruction; marked conjunctival hyperemia in both eyes. The left eye presented opacities with much neovascularization. In vivo confocal microscopy and optical microscopy examination of eyelid lash showed there were lots of Demodex folliculorum mites in the eyelash follicles. Demodex folliculorum mitesin festation and BKC were diagnosed. The female patient was treated with once of IPL and traditional treatment. The third case presented eyelid congestion; meibomian gland pouting and capping; conjunctival hyperemia and marginal infiltrates of cornea with pannus formation in both eyes. BKC was diagnosed. The female patient was treated with twice of IPL and traditional treatment.The first case recovered within 17 days. The second case recovered within 23 days. The third case recovered within 14 days. And their ocular surfaces were stable at 1-month follow-up.Compared with topical medicine treatment of BKC requiring at least 1 month, IPL treatment shortened the course of BKC.
