Conditions

Glaucoma

Interventions

Intervention vs control:Using additional eye drops and/or laser procedure to achieve 20% intraocular pressure (IOP) lowering from baseline. Drug: prostaglandin analogue, brimonidine and carbonic anhyd

Inclusion criteria

Inclusion criteria: 1. To be aged older than 18 years; 2. Best corrected visual acuity more than 20/40; 3. POAG patients diagnosed within 12 months without prior history of glaucoma surgical/laser procedure and receiving not more than one topical IOP lowering medication.

Exclusion criteria

Exclusion criteria: IOP higher than 30mmHg measured at any time points during the screening visit; high myopia (spherical error less than -6.0D); moderate and advanced VF loss (VF MD less than -6dB in the worse eye) or defects close to fixation (any one of the paracentral points with sensitivity less than 10dB); inability to perform reliable VF; suboptimal quality of SDOCT images (see SDOCT imaging); previous intraocular surgery other than uncomplicated cataract extraction; and diabetic retinopathy/maculopathy.
