Comparison of the Effect of Tea Tree Oil Shampoo With Regular Eyelid Shampoo in Meibomian Gland Dysfunction Treatment - 14/11/21
Résumé |
Purpose |
This study is aimed at comparing the effects of tea tree oil (TTO) shampoo with regular eyelid shampoo on the treatment of meibomian gland dysfunction (MGD) signs and symptoms.
Design |
Double-masked randomized clinical trial
Methodology |
Forty patients with MGD were treated by daily eyelid scrubbing with TTO shampoo in one eye and regular eyelid shampoo in the other one. Before treatment and then after 1 and 3 months, the effect on ocular surface symptoms, tear production and stability, and conjunctival and eyelid signs of the 2 eyes were compared.
Results |
Plugging and capping of meibomian gland orifices, foamy tear, glands expressibility, 5-Item Dry Eye Questionnaire score (DEQ5), and tear breakup time were improved more significantly in TTO shampoo–treated eyes (capping P = .050, plugging and glands expressibility P = .001, others P < .001). In spite of improvement in both eyes, scores of meibum quality, conjunctival hyperemia, corneal and conjunctival staining, and Schirmer1 test value showed no statistically significant difference between the eyes (P = .06, .187, .192, .19, respectively). Moreover, eyelid margin telangiectasia resolved only in TTO shampoo–treated eyes (P < .001). Trichiasis and distichiasis changed in neither group (P > .99). Furthermore, ocular surface irritation during scrubbing was more common with TTO shampoo (P = .002).
Conclusion |
TTO shampoo was found to be more efficient than regular eyelid shampoo in controlling MGD signs and symptoms although ocular surface irritation during its application was more frequent.
