Аннотация научной статьи по клинической медицине, автор научной работы — Wang Shudan, Zhang Hong

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.

Ophthalmology hospital of First Affiliated Hospital of Harbin Medical University, Harbin, China

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 conjunctival 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. Key words: blepharokeratoconjunctivitis (BKC); treatment; intense pulsed light.

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 [1].

Case report

The first case was a 10-year-old boy. He presented eyelid congestion; crusting and scaling

at the eyelash root; meibomian gland obstruction and conjunctival hyperemia in both eyes (Fig. 1).

The left eye presented old central corneal scarring with neovascularization. BKC was diagnosed. He was treated with three times of IPL and traditional treatment. The corneal scarring and neovascularization reduced after first IPL treatment and he recovered within 17 days (Fig. 2).

Fig. 2. After treatment: the crusting and scaling disappeared; the obstruction of meibomian gland disappeared ; corneal neovascular-ization was faded away and the lesion reduced

The second case was an 18-year-old girl. She presented scaling and sleeve-form crusting at the eyelash root; meibomian gland arranged irregularly with opening obstruction; marked con-junctival hyperemia in both eyes. The left eye presented opacities with much neovascularization (Fig. 3).

Fig. 1. Before treatment: eyelid congestion; crusting and scaling at the eyelash root, meibomian gland obstruction and moderate con-junctival hyperemia; there was presence of old central corneal scarring with neovascularization in left eye

Fig. 4. After treatment: the eyelid congestion reduced; scaling and sleeve-form crusting disappeared; the obstruction of meibomian gland reduced; conjunctival hyperemia and corneal neovasculariza-tion disappeared; the opacities reduced

The third case was a 46-year-old woman. She presented eyelid congestion; meibomian gland pouting and capping; conjunctival hypere-mia and marginal infiltrates of cornea with pan-nus formation in both eyes (Fig. 5).

Fig. 5. Before treatment: eyelid congestion; meibomian gland pouting and capping; conjunctival hyperemia and marginal infiltrates of cornea with pannus formation in both eyes

BKC was diagnosed. She was treated with twice of IPL and traditional treatment. She recovered within 7 days (Fig. 6).

Fig. 3. Before treatment: eyelid congestion; scaling and sleeve-form crusting at the eyelash root, meibomian gland arranged irregularly with opening obstruction; marked conjunctival hyperemia and opacities covered the pupil accompanied with much neovascularization in left eye

In vivo confocal microscopy and optical microscopy examination of eyelid lash showed there were many. Demodex folliculorum mites in the eyelash follicles. Demodex folliculorum mitesin festation and BKC were diagnosed. She was treated with once of IPL and traditional treatment. She recovered within 23 days (Fig. 4).

Fig. 6. After treatment: eyelid congestion and conjunctival hypere-mia disappeared; meibomian gland pouting and capping disappeared; the pannus faded away

Discussion

The main clinical manifestations of BKC consist of inflamed eyelids, anterior lid margin telangiectasia, accumulations of hard, fibrinous and crusting scales around the base of the cilia. In chronic cases, there are other common symptoms such as ulceration, lid notching, thinning or loss

of lashes, or misdirection of lashes. Conjunctival alteration includes mild to moderate papillary and follicular hypertrophy of the palpebral conjunctiva. In acute exacerbations, additional inferior corneal involvement (punctate epithelial erosions, marginal infiltrates, sterile marginal abscesses) is also seen [2]. BKC is the result of an underlying cytokine and inflammatory-mediated process affecting both the meibomian glands and the ocular surface [1]. It finally leads to a series of inflammatory reactions and tear film instability. Tetz

[3] suggested patients with BKC could present a spectrum of inflammatory and immunologic corneal disorders: punctate epithelial erosions represent an effect of bacteria exotoxins; marginal infiltrates and ulcers represent an antigen-antibody reaction; phlyctenules indicate a delayed hyper-sensitivity reaction. Those graded with mild disease had only corneal epithelial involvement without stromal scarring, for example, punctate epithelial erosions or superficial punctate keratitis; conjunctival hyperaemia and mild conjunctival stromal oedema; active peripheral new vessels involving < 3 clock hours; mild papillary hyperplasia and small follicles (<5). Moderate disease was defined as the additional presence of corneal stromal scarring, with or without vascu-larization; marked conjunctival hyperaemia and conjunctival stromal oedema; significant tissue thickening; active peripheral new vessels involving >3 clock hours or extending to the pupil margin; moderate papillary hyperplasia and follicles (5-10). Severe disease was defined as corneal scarring with significant stromal thinning; con-junctival or corneal ulceration; severe conjuncti-val oedema; active new vessels extending to central zone; marked papillary hyperplasia and follicles (>10) [4-6]. The treatment for blepharoker-atoconjunctivitis includes eyelid hygiene, warm compresses, topical and systemic antibiotics, topical and systemic immunosuppression. By using such treatments remission can be successfully achieved within 3 months. Currently, there is a lack of an effective, standardized treatment regimen for this disease, with potentially sight-threatening complications like amblyopia, thinning, and perforation and treatment-related complications such as steroid-induced glaucoma, cataracts, ulcers, and reactivation of viral keratitis

[4] and some systemic adverse effects like photo-toxicity and gastrointestinal disturbance [7].

Intense pulsed light (IPL) devices contain high-intensity light sources, which emit polychromatic light extending from the visible (515 nm) to the infrared spectrum (1200 nm)[8]. IPL has been used in dermatology practices for several years as a treatment for rosacea and acne

[9] .The pivotal mechanism of IPL involves the principal of selective photothermolysis, in which light energy that comes in contact with tissue is preferentially absorbed by a chromophore and converted into heat. Appropriate wavelengths can be selected for different targets depending on the absorption behavior and the penetration depth of the light emitted, and specific filters can be chosen to limit the delivery of wavelengths to the treatment area resulting in selective thermal delivery [8]. In 2002, Rolando Toyos discovered the positive ophthalmic effects of IPL on his patients who underwent treatment for facial rosacea [9]. It shows IPL is an effective treatment for patients with evaporative dry eye disease that can significantly reduce symptoms and improve mei-bomian gland function [10]. A prospective, double-masked, placebo-controlled, paired-eye study by Jennifer P. Craig showed IPL improved tear film quality. The pulse intensity ranged from 9 to 13 J/cm2 and was inversely related to the individual skin phototype level as determined by the Fitzpatrick grading scale.

Analysis of these three patients showed that the first two cases of BKC patients are severe and of the last case is moderate. Using IPL treatment combined with topical drug treatment, it showed a good effect for these three cases of BKC. Remission occurred within 17days in the first case, 23 days in the second case and 7 days in the third case. Our observation indicated that BKC with Demodex folliculorum mites infestation is more serious and more difficult to treat. IPL is non-invasive and easy to operate that can be completed in five minutes. It can quickly reduce the corneal neovascularization and make the lesion absorbed. It can shorten the process of the disease and increase the vision more quickly compared with the traditional treatment. As BKC is chronic and recurrent, additional treatments are often required for 2 months to maintain symptom relieve. According to the feature of IPL, we suggest the mechanism of IPL for BKC is that IPL allows for selective ablation of the neovascularization and the superficial vessels. It then reduces telangiectasias and decreases inflammation of ocular surface and the meibomian glands. Another potential mechanism includes reduction of bacteria and Demodex folliculorum mites growth on the eyelids. There is also a temporary local thermal effect that warms the meibomian gland secretions. This warming effect can allow for improved manual expression of inspissated meibum within the meibomian glands after application of the light. With improved meibum secretion and viscosity, the tear film can become more stable. In conclusion, IPL therapy is a safe and effective treatment for BKC.

Although IPL has a relatively good safety profile, some ocular complications have been reported when treated without proper eye protection. It has been reported that IPL therapy could cause anterior uveitis, permanent iris atrophy and pupillary

defects [11]. Therefore, it is essential for physicians to protect eyes in IPL treatment. More research is needed with more patients and longer follow-up time to assess the long-term outcomes of IPL treatment for BKC.
