Exclusion criteria

Unable to give consent or take part in all study procedures

 

Other conditions that might interfere with the assessment of the eye such as cataract or prevent the macular oedema from settling such as vitreomacular traction, epiretinal membrane, to a degree that would in the opinion of the investigator affect response to treatment; conditions that would prevent the visual acuity improving such as foveal atrophy, uveitis

 

Previous macular laser within 4 months in the study eye

 

Previous peripheral (PRP) laser in the study eye

 

Previous injection therapy within last 6 months in the study eye

 

Pregnant

 

Uncontrolled systemic illness that in the opinion of the investigator would preclude involvement
