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. <b><i>Methods:</i></b> A monocentric prospective study has been conducted from 2021 to 2023 on patients presenting with moderate MGD and COSP non-responsive to conventional treatments of MGD. Neuropathic pain components were suspected when severe discomfort (OSDI score above 33/100) was observed despite moderate objective signs. Three sessions of IPL were performed at a two-week interval. The primary outcome was change in OSDI at day 60. Secondary outcomes included OSDI modification at D120, DEQ-5, and Pentascore results at D60/D120, together with changes in clinical [Schirmer I, Fluorescein Break-up time (BUT), fluorescein staining, and MGD classification] and paraclinical tests [noninvasive BUT, tear meniscus height (TMH), and meibography]. <b><i>Results:</i></b> A significant improvement of COSP (<i>p</i> < 0.05 for changes in OSDI and Pentascore results) was observed 2 and 4 months after the last IPL session, together with an improvement in tear film stability, corneal epitheliopathy, meibomian gland obstruction, and TMH. <b><i>Conclusion:</i></b> The results of this study suggest the beneficial effect of IPL on neuropathic component of COSP associated with MGD.

Multi-characteristic opsin (MCO)-based optogenetic therapy allows the recruitment of residual cells of the retina in LCA for alternative vision transduction while being mutation-agnostic. Using <i>rd12</i> mice, we investigated the <i>in vivo</i> efficacy of an adeno-associated virus2 (AAV2)-transduced ambient light-activatable MCO (MCO-010) containing a metabotropic glutamate receptor-6 bipolar cell-specific promoter/enhancer. <b><i>Methods:</i></b> Mice requiring > 40 s to reach and board a dimly lit hidden platform in a water-maze were selected and randomly divided into 2 cohorts.

Spectral-domain optical coherence tomography (SD-OCT), hematoxylin and eosin staining of retinas, and electroretinographic (ERG) studies were also conducted. <b><i>Results:</i></b> Safety of MCO-010 in <i>rd12</i> mice was confirmed by the lack of significant detrimental changes in the mouse behavior, b-wave amplitudes and in retinal thickness. <i>rd12</i> control mice performed relatively poorly in the water-maze test requiring ≥ 30-60 s to find and board the platform.
