Effects of Intense Pulsed Light on Presumed Neuropathic Pain Associated with Meibomian Gland Dysfunction: A Before–After Study

Meibomian gland dysfunction (MGD) may cause chronic ocular surface pain (COSP) with a neuropathic component that can significantly impact quality of life and be poorly responsive to conventional treatments of MGD. Intense pulsed light (IPL) is an emerging treatment already acknowledged as improving refractory MGD, potentially modulating inflammatory mediators on the ocular surface. This study aimed to assess the impact of IPL on COSP associated with unresponsive MGD.
