Abstract

The Stevens-Johnson syndrome (SJS) is a rare and severe condition, affecting skin and mucous membranes. The exact cause of the syndrome often can not be identified, but it is believed that this disease represents an exaggerated lymphocytic response, triggered by a drug or infection.SJS covers a wide spectrum of ocular manifestations that are associated with significant visual morbidity. Acute inflammation combined with a decrease in the tear production and corneal chronic microtrauma related to blink, can lead to limbal stem cell failure and keratopathies or infections. A study conducted by the Department of Ophthalmology - UNIFESP, the largest referral center for this disease in the country, reveals that among the ocular complications observed during the chronic syndrome, corneal neovascularization was the most common, followed by scarring, symblepharon, corneal conjunctivalization, entropion, trichiasis and ankyloblepharon. These complications lead to blindness in a large number of patients. Visual impairment and ocular discomfort continue throughout the life, reducing patients quality of life and requiring medical treatment indefinitely.In order to minimize one of the most common ocular complications of the disease and thereby decrease its morbidity, we propose, in this paper, the comparison of the efficacy of topical bevacizumab and sunitinib in reducing corneal neovascularization in patients with ocular sequelae caused by SJS. In recent years these new family of drugs, originally used in cancer treatment, emerged as the therapeutic promise of neovascularization by inhibiting the sites of action of VEGF-A, an important angiogenic factor of the cornea.
