Intraocular Pressure (IOP) Lowering Efficacy of Transdermal Latanoprost Therapy

Glaucoma is the leading cause of irreversible blindness worldwide, with primary open-angle
glaucoma the most common form of glaucoma. Vision loss is caused by damage to the optic
nerve. The modern goals of glaucoma management are to avoid glaucomatous damage, nerve
damage, preserve visual field and total quality of life for patients with minimal side
effects.

Although intraocular pressure is only one of the major risk factors for glaucoma, lowering
it via various pharmaceuticals and/or surgical techniques is currently the mainstay of
glaucoma treatment. Intraocular pressure can be lowered with medication, usually eye drops.
There are several different classes of medications to treat glaucoma with several different
medications in each class. In order to prevent blindness from glaucoma, it is critical that
patients take their glaucoma eye drops accurately and faithfully for the rest of their
lives. Poor compliance with medications and follow-up visits is a major reason for vision
loss in glaucoma patients. In addition, coordination involved in placing an eye drop in the
eye is considerably more difficult and unpleasant to patients than many other therapies.
Thus, localized transdermal eyelid lotion would create a leap in safety of drug delivery
while at the same time rendering ocular drugs easy and non traumatic to use.

Inclusion Criteria:

patient factors such as cognition, reliability, motivation, and ability to obtain
reliable transportation to study site.

Exclusion Criteria:

put the patient at a significant risk, may confound the study result or may interfere
significantly with the participation in the study
