Embodiments include methods, apparatuses, and systems for reducing elevated intraocular pressure (IOP) in a patient to either prevent or treat open-angle glaucoma. Heat is applied to the trabecular meshwork in the patient's eye without damaging proteins in the trabecular meshwork. The application of heat to the trabecular meshwork has the effect of relaxing or loosening protein clogs or other inhibitors in the trabecular meshwork, which are either reducing or obstructing of the outflow of aqueous humor, thereby increasing the patient's IOP and causing ocular hypertension (OHT). By loosening or relaxing clogs or other inhibitors in the trabecular meshwork, the outflow path for aqueous humor is increased or restored, which can lower IOP and either prevent or treat glaucoma. Force may also be applied to the patient's eye to apply pressure to the trabecular meshwork to further assist in the loosening or relaxing of clogs or other inhibitors in the trabecular meshwork.

Abrégé

Apparatuses, systems, and methods of treating meibomian gland dysfunction. Heat is applied to the patient's eyelid or surrounding tissue to apply heat to the patient's meibomian glands. The application of heat assists in the expression of obstructions or occlusions in the meibomian glands to restore sufficient sebum flow to the lipid layer to treat dry eye. A force may also be applied to the patient's eyelid or surrounding tissue to improve conductive heat transfer and reduce blood flow in the tissue that causes convective heat loss. Thus, the application of force can further increase the temperature level and/or reduce the time to reach desired temperature levels for removing obstructions.

A method of treating meibomian gland dysfunction. Heat is applied to the inside of the eyelid to provide conductive heat transfer to the meibomian glands. The application of heat assists in the expression of obstructions or occlusions in the meibomian glands to restore sufficient sebum flow to the lipid layer to treat dry eye. Temperatures at the meibomian glands reach desired levels more quickly and efficiently when heating the inside of the eyelid. Reaching such higher temperature levels may be instrumental in removing obstructions in the meibomian glands. Less time may also be required to reach desired temperature levels when applying heat to the inside of the eyelid. A force may also be applied to the outside of the patient's eyelid to improve conductive heat transfer and reduce blood flow in the eyelid that causes convective heat loss. Thus, the application of force can further increase the temperature level and/or reduce the time to reach desired temperature levels for removing obstructions.

Abrégé

According to the present invention, there is provided a method of treating meibomian gland dysfunction in a mammal wherein an occlusion blocks at least a portion of the flow of naturally occurring secretion out of a gland channel orifice. The invention comprises selecting a device capable of delivering a jet of heated medium. The device is positioned such that when the jet is it is applied to the exterior surface of the eyelid, proximate to the gland channel orifice, a jet of heated medium is applied to the exterior surface of the eyelid proximate to the gland channel orifice at a pressure of from about 2 psi to about 30 psi. Application of the jet of heated medium is maintained for sufficient time to loosen, break up, fracture, soften or liquefy at least a portion of the occlusion such that at least a portion of the occlusion is removed. In an exemplary embodiment, the medium is water heated to a temperature of between about 42° C. and about 46° C. Depending on the particular type and composition of the obstruction, the fluid jet operates to melt or soften the obstruction and to milkingly move the corpus of the softened obstruction up the gland channel from the end opposite the meibomian gland orifice and out of the gland orifice. Repeated application of the heated fluid jet may also be necessary to soften and/or express the obstruction.
