PIO Laser Sclerectomy IOP SLT Sclerectomy

Effect of Selective Laser Trabeculoplasty on the Intraocular Pressure Nycthemeral Rhythm.

The main objective of this study is to characterize the changes in IOP over 24 hours after selective trabeculoplasty SLT (before and 1 and 6 months after treatment, decreased IOP, type of rhythm, mesor, acrophase, amplitude). The secondary objective is to evaluate changes in ocular perfusion pressure (arterial pressure - IOP) and ocular blood flow in the optic nerve head after selective laser trabeculoplasty.

Inclusion Criteria:

• Primary Open-Angle Glaucoma
• IOP more than 21 mmHg
• Progression under maximal medical therapy
• aged more than 18 years

Exclusion Criteria:

• Pregnant woman
