Purpose
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.

Criteria
Inclusion Criteria:

- Diagnosis of pediatric glaucoma or elevated intraocular pressure.
- Evidence of a personally signed and dated informed consent document indicating that the subject (and/or a legally acceptable representative) has been informed of all pertinent aspects of the study. A signed and dated assent will be required where applicable according to local laws.
For treated subjects only:
- Continuously treated with latanoprost for at least 1 month within the year prior to the baseline examination.
For untreated subjects only:
- Continuously treated with latanoprost or other topical prostaglandin analogues for less than one month prior to the baseline examination (based on the best knowledge of treating ophthalmologists), and unlikely to be treated with latanoprost or other topical prostaglandin analogues during the three-year study period; OR
