Abstract: Ocular surface interferometry devices, systems, and methods are disclosed for imaging an ocular tear film. An imaging device can be focused on the lipid layer of the tear film to capture optical wave interference interactions of specularly reflected light from the tear film combined with a background signal(s) in a first image, wherein the specularly reflected light may be produced from various portions of the ocular tear film by obliquely illuminating various portions of the ocular tear film with a multi-wavelength light source, such as in a tiling pattern(s). The imaging device can also be focused on the lipid layer to capture a second image containing the background signal(s) present in the first image. The second image can be subtracted from the first image to reduce and/or eliminate the background signal(s) in the first image to produce a resulting image, which can used to measure a tear film layer thickness.

Abstract: Apparatus and methods for treating dry eye include an energy source configured to apply energy to an obstruction located in a meibomian gland of a patient's eyelid. The apparatus also comprises an insulator configured to be positioned between a rear portion of the patient's eyelid and a surface of the patient's eyeball. An inner surface of the insulator has a curvature greater than that of the patient's eyeball such that an air pocket is formed between the inner surface of the insulator and the patient's eyeball, wherein the air pocket provides additional insulation to reduce or eliminate an amount of heat due to the applied energy from the energy source from being conducted to the surface of the patient's eyeball, such that the applied energy does not cause the temperature to reach a temperature sufficient to cause damage to a corneal or scleral portion of the patient's eyeball.

Abstract: An apparatus providing heat for treatment of an eyelid includes a heater unit configured to apply heat directly to an outer surface of the eyelid when an electrical signal is applied to the heater unit. The heater unit is affixed directly to the outer surface of the eyelid using an adhesive. A temperature regulator applies the electrical signal to the heater unit in order to achieve heating of the outer surface of the eyelid to a specified temperature range. A method is also disclosed that comprises affixing a heater unit directly into contact with the outer surface of the eyelid using an the adhesive. A control signal is applied to the heater unit to generate heat to the outer surface of the eyelid and is maintained for a period of time until the outer surface of the eyelid is heated to a specified temperature range.

Abstract: Methods and apparatuses for determining contact lens intolerance in contact lens wearer patients based on tear film characteristics analysis and dry eye symptoms are disclosed. In embodiments herein, imaging of the ocular tear film is performed during contact lens wear. An analysis of the image of the ocular tear film is performed to determine one or more tear film characteristics of the ocular tear film. The tear film characteristics can be used to determine the effect or possible effect of contact lens wear on the ocular tear film, and thus be used to determine contact lens intolerance of the patient. The tear film characteristics used to analyze contact lens intolerance based on images of the ocular tear film involving contact lens wear may include dry eye symptoms, including but not limited to tear film (e.g., lipid and/or aqueous) thickness, tear film viscosity, and tear film movement rate in the eye.

Abstract: Methods and apparatuses of treating meibomian glands are disclosed. The method comprises applying regulated heat to an eyelid to reach a temperature adequate to melt at least one obstruction within at least one meibomian gland. The method also comprises maintaining the regulated heat for a time period adequate to place the at least obstruction in the melted state. The method further comprises positioning a pressure application device into contact with the patient's eyelid and applying a pressure with the pressure application device over a substantial portion of the eyelid to express the at least one obstruction from the meibomian gland. An apparatus suitable to treat meibomian glands comprises a heater, a controller, and a pressure applicator configured to be placed into contact with the eyelid and apply a pressure over a substantial portion of the eyelid to express the at least one obstruction from the meibomian gland.

Abstract: Background reduction apparatuses and methods of Ocular Surface Interferometry (OSI) employing polarization are disclosed for measuring a tear film layer thickness (TFLT) of the ocular tear film, including lipid layer thickness (LLT) and/or aqueous layer thickness (ALT) and can be used to evaluate and potentially diagnosis dry eye syndrome (DES). In certain disclosed embodiments, a multi-wavelength light source can be controlled to illuminate the ocular tear film. Light emitted from the multi-wavelength light source undergoes optical wave interference interactions in the tear film. An imaging device can be focused on the lipid layer of the tear film to capture optical wave interference interactions of specularly reflected light from the tear film combined with a background signal(s) in at least one image. The at least one image can be processed and analyzed to measure a tear film layer thickness (TFLT), including lipid layer thickness (LLT) and/or aqueous layer thickness (ALT).

Abstract: 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.
