Improving diagnosis and treatment of lid disease

INTERVENTION: Three management strategies are to be used: Latent Heat Goggles, Warm Compresses with a flaxseed pouch, and a Liposomal Spray. The latent heat goggles will be worn for 10 minutes at the 50°C setting. The treatment will be carried out two times within the overall intervention period of 4 hours. The warm compresses (flaxseed pouch) will be heated in a 900W microwave for 30 seconds as per the manufacturers instructions, and then applied to the closed eyes for 5 minutes. The treatment will be performed two times within the overall intervention period of 4 hours. A single application the liposomal spray (TearsAgain) which contains soy lecithin 1.0% will be applied to the closed eye, as per normal patient instructions. The treatment will be applied two times within the overall intervention period of 4 hours. CONDITION: Meibomian gland dysfunction PRIMARY OUTCOME: Therapies for meibomian gland dysfunction will be optimised on the basis of the tear film evaporation rate. SECONDARY OUTCOME: Secondary outcome is the temperature profile of the ocular surface and adnexa, measured with a non‐contact infra‐red thermographer INCLUSION CRITERIA: Symptoms and signs of meibomian gland dysfunction
