A method of treating, reducing, or alleviating a medical condition in a patient is disclosed herein. The method includes administering to a patient in need thereof a biocompatible drug comprising one or more antiviral medications together with one or more cell pathway inhibitors dissolved in a non-toxic semifluorinated alkane, the patient having one or more respiratory tract inflammatory diseases, the one or more cell pathway inhibitors blocking an inflammatory response of inflamed tissue without inhibiting an immune response of the patient, and the semifluorinated alkane evaporating quickly upon administration to the patient so as to leave the biocompatible drug at a desired treatment location. The administration of the biocompatible drug to the patient treats the one or more respiratory tract inflammatory diseases, reduces the symptoms associated with the one or more respiratory tract inflammatory diseases, and/or alleviates one or more respiratory tract inflammatory diseases.

The present invention provides a method of relieving intraocular pressure by inserting a drainage device into the sclera near the trabecular meshwork from a remote location. The path of insertion is made from a corneal incision and avoids contact with the conjunctiva and tenons tissue. The drainage device comprises a tube like structure and may contain a barb at one end to secure the drainage device. A delivery device may be used to insert the drainage device. The delivery device may be inserted through a corneal incision and directed to the desired area for insertion in to the sclera. The delivery device may then be activated to shoot the drainage device into the sclera to promote increased drainage of aqueous humor and reduce the build up of intraocular pressure.
