Description

Inclusion Criteria:

1. Male or female, 18 years or older at the time of the screening examination
2. Subject diagnosed with bilateral OAG or OH
3. Subject IOP is currently controlled (< 21 mmHg) with a topical prostaglandin or in conjunction with one other topical ocular hypotensive drug, not including any fixed-combination formulations (i.e., Cosopt, Combigan, Azarga, etc.) for at least one month or more
4. Subject who has lower and upper puncta > 0.5 mm and < 0.9 mm (pre-dilation) in both eyes
5. Subject must be able and willing to read, comprehend and give Authorization for Use/Disclosure of Health Information (HIPAA) and informed consent
6. Subject must be willing to comply with study instructions, dosing (if applicable), agree to make all office appointments, and complete the entire course of the study
7. Women of child-bearing potential must not be pregnant or lactating, must have a negative pregnancy test at screening and must be practicing an adequate method of birth control, including intrauterine device (IUD); oral, dermal ("patch"), implant or injected contraceptives; tubal ligation; or barrier methods with spermicide
8. Subject has a central corneal thickness of > 500 μm and < 600 μm in study eye
9. Subject has a BCVA or pinhole visual acuity (Snellen) of 20/100 or better in both eyes

Exclusion Criteria:

1. Subject with a history of non-response to topical prostaglandin eye drops for OAG/OH
2. Subject with angle-closure glaucoma, neovascular glaucoma, traumatic glaucoma or iridocorneal endothelium syndrome in either eye
3. Subject with a known sensitivity to latanoprost, timolol, fluorescein, topical anesthetic, silicone, any inactive ingredient of the L-PPDS or any other products required for the study procedures
4. Subject with a history of intolerance to topical beta-blocker therapy
5. Subject with > 0.8 vertical cup or completely notched optic nerve head rim in either eye
6. Subject with any functionally significant visual field loss or progressive field loss within the last year in either eye
7. Subject with a history of complications, AEs, trauma or disease in the nasolacrimal area, whether or not it was due to punctal plug wear, including but not limited to dacryocystitis, inflammation or canaliculitis in study eye
8. Subject with structural lid abnormalities (i.e., ectropion, entropion) in study eye
9. Subject with an active lid disease in either eye (i.e., moderate or severe blepharitis, meibomianitis) that requires medical treatment
10. Subject with a history of chronic/recurrent inflammatory eye disease (i.e., scleritis, uveitis, herpes keratitis) in either eye
11. Subject who would require the use of any ocular topical medication(s), an over-the counter drop(s), ointment(s) or gel(s), other than the study ocular hypotensive medication(s) in either eye during the study period
12. Subject who has had any ophthalmic surgical procedures (i.e., glaucoma laser, minimally invasive glaucoma surgery, cataract, refractive, etc.) in study eye within the last six months or will require ophthalmic surgery before completing the study

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: Group A. L-PPDS single occlusion; Latanoprost Punctal Plug Delivery System (L-PPDS) continuous single occlusion; L-PPDS will be inserted in the lower punctum and no plug will be inserted in the upper punctum of each eye; L-PPDS will remain for a period of 14 weeks.	Drug: Latanoprost Punctal Plug Delivery System (L-PPDS); Latanoprost Punctal Plug Delivery System (L-PPDS)
Experimental: Group B. L-PPDS double occlusion; Latanoprost Punctal Plug Delivery System (L-PPDS) continuous double occlusion; L-PPDS will be inserted in the lower punctum and non-therapeutic (NT) plug will be inserted in the upper punctum of each eye and both will remain for a period of 14 weeks.	Drug: Latanoprost Punctal Plug Delivery System (L-PPDS); Latanoprost Punctal Plug Delivery System (L-PPDS)
