Abstract

Purpose

To investigate the effectiveness of combined photodynamic therapy with verteporfin and intrastromal injection of bevacizumab for the treatment of corneal neovascularization in patients with Stevens–Johnson syndrome (SJS).

Methods

Eight eyes of eight patients with SJS having corneal neovascularization who were refractory to 1% prednisolone instillation received photodynamic therapy with verteporfin (6 mg/m2) combined with intrastromal bevacizumab injection (2.5 mg/0.1 mL). Best-corrected visual acuity and intraocular pressure were assessed, and slit-lamp biomicroscopic examination was performed before treatment and at 1 week and every month. A chronic ocular manifestation score was assigned based on the involvement area or the severity before treatment. The cumulative length of corneal blood vessels and area of corneal neovascularization were measured by anterior segment photographs before and after treatment.

Results

At 3 and 6 months after treatment, all eyes showed regression of corneal neovascularization. Complete regression was achieved in five eyes (62.5%) and partial regression in three eyes (37.5%). Among five patients who were followed up for more than 1 year, two eyes maintained complete regression and one eye maintained partial regression at 1 year. However, two eyes with severe chronic ocular manifestation showed revascularization.

Conclusions

Combined photodynamic therapy with intrastromal bevacizumab injection can effectively inhibit corneal neovascularization in patients with SJS. However, patients with severe chronic ocular manifestation may exhibit revascularization.
