Brief Summary:
This is a non-interventional, prospective, longitudinal cohort study. A total of 150 pediatric subjects with glaucoma or elevated intraocular pressure, including 75 latanoprost-treated subjects and 75 non-topical prostaglandin analogue treated subjects, will be enrolled from ophthalmic hospital clinics and academic ophthalmic centers. As a non-interventional study, the study subjects' continued use of latanoprost and assessments of ocular events will be obtained through the routine medical follow-up with treating ophthalmologists or other designated members of the medical care team.

Condition or disease Intervention/treatment
Glaucoma Ocular Hypertension Other: No intervention other than routine medical care

Detailed Description:
At least 40 subjects in each of the following age groups: 1-<5 years and 5-<18 years. No minimum required numbers in the <1 year age group.
