A jojoba formulation has been developed for administration to the meibomian gland, for treatment of the symptoms of dry eye, and / or for drug delivery to the meibomian gland. The formulation incorporates the natural product jojoba wax, or components thereof, to enhance the spreading of the artificial tear as well as stabilize the tear film. The jojoba wax tear relieves irritation and discomfort as well as sharpens the blurred vision. Jojoba, because of its close chemical and physical properties to meibomian gland secretions, is effective upon topical application to penetrate the lid margin to reach the gland tissues where it may exert a therapeutic effect with or without an adjunctive agent.

Methods and apparatuses are disclosed for the diagnosis and removal of the devitalized and / or dead cell material formed in the lid margin to attempt to restore a normal lid margin. In this manner, the devitalized and / or dead cell material are removed or the amount present is reduced or no longer present to prevent, reduce, or affect the transport of lipid secreted by the meibomian glands to the tear film to reduce evaporative dry eye and improve dry eye conditions in patients. The diagnosis and removal of devitalized and / or dead cell material may be performed at desired intervals. Patients that suffer from conditions that block meibomian gland orifices, partial, infrequent, or inhibited blinking resulting in reduced lipid secretions from meibomian glands, and / or blockages in meibomian gland channels reducing secretion of lipids through the meibomian gland orifices may require more frequent diagnosis and treatment to remove devitalized and / or dead cell material.

The invention discloses an eyelid positioning method based on strong direction weighted edge detection and RNL goodness of fit. An existing straight line fitting positioning method is high in positioning speed but low in positioning precision. The parabola fitting positioning method is high in fitting positioning precision, but low in positioning speed. The method comprises the following steps: segmenting upper and lower eyelids according to an iris circle center position, and determining upper and lower eyelid areas; secondly, preprocessing an image before eyelid detection by using a strong direction weighted edge-preserving denoising smoothing filtering operator; secondly, suppressing eyelash interference by using a strong direction weighted edge detection operator, and dynamically selecting edge detection operator parameters according to gray scale contrast values of regions above and below the eyelid edge in the iris image to obtain candidate eyelid edges to be fitted; and finally,fitting eyelid edges by adopting a least square method parabola, and screening eyelid edge selection points by taking RNL goodness of fit as an index to finish eyelid positioning. The method has goodrobustness, and an ideal positioning result can be obtained even for an upper eyelid which is shielded by eyelashes.

The invention provides eye lids margin illumination distance and levator palpebrae superior muscle strength measuring equipment. The equipment comprises a hook face fixing piece, a luminous element, a geisoma compressing piece and a pulling rod, wherein the hook face fixing piece is provided with at least one first through-hole, the pulling rod is connected to the geisoma compressing piece after being inserted into the first through-hole, and the light of the luminous element can form a liminescent printing point in the most protruding point of the cornea. The eye lids margin illumination distance and levator palpebrae superior muscle strength measuring equipment can perpendicularly fix the geisoma when levator palpebrae superior muscle strength is measured, and thus operation errors is reduced during measurement. An integrated measurement way makes a straightedge directly attach under the measuring device, the operator can directly read a corresponding number value, thus the operation time is shortened, the errors are further lowered, and precision of data is improved. Therefore, insufficient correction or overcorrection caused by insufficient ptotic amount judgment is avoided, and the surgery effect is improved. The whole standardized measuring tool can be fixed at the head of a patient, thus the operation is simpler and convenient, and the compatibility and the compliance of the patient are improved.
