Therapeutic Efficacy and Safety of Intense Pulsed Light for Meibomian Gland Dysfunction in Patients with Chronic Ocular Graft-Versus-Host Disease

Abstract

ABSTRACT Purpose To evaluate the efficacy and safety of intense pulsed light combined with meibomian gland expression (IPL-MGX) for treating meibomian gland dysfunction (MGD) associated with chronic ocular graft-versus-host disease (oGVHD). Methods This retrospective study included 18 patients (18 eyes) with Fitzpatrick skin type ≤ IV, who underwent 3 to 8 sessions of IPL-MGX. Dry eye symptomology, ocular surface parameters, and adverse events were evaluated. Results Of 18 eyes, 83.3% and 66.7% showed severe oGVHD and severe MGD, respectively. At 4 weeks after the final session, significant improvements in the OSDI (P < 0.001), SPEED (P = 0.001), meibum expressibility (P < 0.001), and meibum quality (P = 0.016) were observed. At 12 weeks after, the OSDI (P = 0.009), SPEED (P = 0.002), and meibum expressibility (P = 0.008) significantly improved. No adverse events owing to IPL were reported. Conclusion IPL-MGX may improve the ocular symptoms, ameliorate meibomian gland secretion, and is considered as a safe treatment for MGD in oGVHD patients.
