| Titre | A new treatment for obstructive meibomian gland dysfunction - Blephasteam |
| But | Obstructive meibomian gland dysfunction (MGD) frequently becomes a chronic complaint with various symptoms related to dry eye and discomfort. Research indicates a pivotal role for heat therapy as part of any successful management plan, but delivery of constant temperature is vital. This study evaluated the performance of a novel device designed to deliver controlled, latent, moist heat to the eyelids and surrounding area. |
| Méthodes | The signs, symptoms and ocular temperature of 25 normal subjects (M8, F17; age 29.2±5.7yrs) were recorded before and after a ten minute application of the Blephasteam® device. Ocular temperature (non-invasive ocular thermography; A40 Flir, UK), tear film stability, intra-ocular pressure (IOP), ocular hyperaemia and surface staining were recorded. Results were checked for normality and compared using paired t-tests. |
| Résultats | Temperatures in both eyelids remained significantly greater after application (upper +1.7±0.9C; lower +2.1±0.7C, p<0.0005). Bulbar conjunctival hyperaemia significantly decreased after treatment (p<0.005), but limbal and palpebral hyperaemia were remained similar (p=0.33 and p=0.11 respectively). No significant change in corneal or conjunctival staining was observed (p=0.74 and p=0.97, respectively). Tear film stability was unchanged in this normal cohort (p=0.12). There was no significant change in IOP (13.8±2.0mmHg vs 12.9±2.2mmHg; p=0.092). |
| Conclusion | The Blephasteam® device provides effective levels of warming that would be sufficient to melt meibum, and no adverse ocular responses were recorded in this cohort. Even in this normal cohort, ocular surface redness appears less after treatment. |
