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.

Outcome Measures
Primary Outcomes (1)
Change From Baseline to Last Available Observation in Best Corrected Visual Acuity (BCVA) (Snellen or Equivalent)
Patients familiar with the letters of the alphabet were evaluated using Snellen visual acuity. Patients who were unable or unfamiliar with the letters of the alphabet were evaluated using charts made up of numbers, pictures (eg, Schering's Children's Eye Chart or Allen Cards), E's, or Landolt's broken rings, and other methods which were equivalent to Snellen acuity eg, HOTV testing).
Evaluated at Baseline, 6 months, 12 months, 24 months and 36 months
Secondary Outcomes (13)
Number of Participants With Clinically Meaningful Change in Refractive Error
Evaluated at Baseline, 6 months, 12 months, 24 months and 36 months
Change From Baseline to Last Available Observation in Horizontal Corneal Diameter (by Caliper and/or Ruler)
Evaluated at Baseline, 6 months, 12 months, 24 months and 36 months
Change From Baseline to Last Available Observation in Intraocular Pressure (IOP)
Evaluated at Baseline, 6 months, 12 months, 24 months and 36 months
Cup-to-disc Ratio (for Assessment of Optic Nerve Changes/Structures) - Number of Participants With Clinically Significant Deterioration in Cup/Disc Ratios
Evaluated at Baseline, 6 months, 12 months, 24 months and 36 months
Visual Field Defects - Number of Participants With Clinically Significant Deterioration of Visual Field Defects.
Evaluated at Baseline, 6 months, 12 months, 24 months and 36 months
- +8 more secondary outcomes
Study Arms (2)
Latanoprost-treatment group
Non-topical prostaglandin analogue treatment group
Interventions
Subjects continuously treated with Latanoprost for at least one month Latanoprost treatment during the study period.
Eligibility Criteria
Pediatric populations diagnosed with glaucoma or elevated intraocular pressure
You may qualify if:
- Male or female \<18 years of age (neonates must be at least 36 weeks gestational age).
- 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
- No prior treatment with latanoprost or other topical prostaglandin analogues, and unlikely to be treated with latanoprost or other topical prostaglandin analogues during the three-year study period.
You may not qualify if:
- Unable/unwilling to comply with protocol.
- Pregnant or nursing females at baseline.
- For treated subjects only: a history of allergy or hypersensitivity to any of the ingredients contained in latanoprost (e.g., hypersensitivity to benzalkonium chloride).

Limitations and Caveats
Inherent limitations of an observational study design (eg, lack of randomization), this was subject to the design/data-related limitations mainly Visual acuity, IOP, and visual field assessments in \<5 years old age group were less reliable
