Abstract:
In one embodiment consistent with the present invention a method of treating mammalian meibomian glands (10) involves clearing the glands by applying a regulated heat (104) to an eyelid containing the meibomian glands to a temperature adequate to melt obstructions in the meibomian glands to put the obstructions in a fluid or suspension (melted) state and maintaining the heat for a time period adequate to melt the obstructions. The glands can then be mechanically treated to express fluid from the glands (108), wherein the treating is carried out either during the time period or after the time period but while the obstruction remains in a fluid state. Subsequent pharmacological treatment of the glands by use a pharmacological agent (topical or systemic) (112) can then be used to assist in maintaining proper flow of lipids from the glands. This abstract is not to be considered limiting, since other embodiments may deviate from the features described in this abstract.
Abstract:
A method of treating meibomian gland dysfunction is disclosed. The method includes directing RF energy to an internal portion of a meibomian gland, selectively targeting an obstruction within a duct of the meibomian gland with the applied RF energy to melt, loosen, or soften the obstruction, and expressing the obstruction from the duct of the meibomian gland. An apparatus for treating meibomian gland dysfunction is also disclosed. The apparatus comprises at least one RF electrode configured to direct RF energy to an internal portion of a meibomian gland located in an eyelid of an eye, the at least one RF electrode further configured to selectively target an obstruction within a duct of the meibomian gland with the applied RF energy to melt, loosen, or soften the obstruction. The apparatus also comprises at least one expressor configured to express the obstruction from the duct of the meibomian gland.

Abstract:
A method and apparatus for treating gland dysfunction caused by gland obstruction in order to restore the natural flow of secretion from the gland comprises the application of a combination of energy, suction, vibration, heat, aspiration, chemical agents and pharmacological agents to loosen and thereafter remove the obstructive material.

Abstract:
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. Reaching increased temperature levels may improve the melting, loosening, or softening of obstructions or occlusions in the meibomian glands while reducing the amount of time to reached desired temperature levels and/or aid in reducing discomfort to the patient during treatment.
Abstract:
Consistent with certain embodiments, an apparatus provides regulated heat to at least one of a patient's eyelids, using a heater unit (38) having a heating element (42) that produces heat that is transferred to the patient's eyelid when an electrical signal is applied thereto. A temperature regulator applies an electrical signal to the heating elements (42) in order to achieve heating of the heating elements (42) to a specified temperature range. This abstract is not to be considered limiting, since other embodiments may deviate from the features described in this abstract.
Abstract:
A method of evaluating dry eye in humans wherein the flow of naturally occurring secretion to the eye is reduced or stopped due to the presence of an obstruction of a meibomian gland (20) in the eyelid involves applying a pressure to the eyelid that mimics pressure applied during blinking; and simultaneously imaging the glands to diagnose the condition of the meibomian gland (20). This abstract is not to be considered limiting, since other embodiments may deviate from the features described in this abstract.
Abstract:
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 (O). The invention comprises selecting a device capable of delivering a jet of heated medium. The device is positioned such that when the jet is applied to the exterior surface of the eyelid, proximate to the gland channel orifice (O), 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.
