Objective Measurements of Lens Opacification After Intravitreal Injections

Objective Measurements of Lens Opacification After Intravitreal Injections (MOC-IVT)

The main hypothesis is the opacification of the lens would be increase by the IVT.

The opacification of the lens can be objectived by :

• the objective scatter index (OSI) on the OQAS device
• the average lens density (ALD) on the IOLMaster device.

Eligible patients will be followed at least 12 months after in intravitreal injection and the opacification of their lens is regularly controlled with OSI and ALD.

The objective is to study the dynamics of lens opacification in IVT-treated eyes evaluated by OSI for at least 1 year.

Inclusion criteria:

• An indication of an intravenous injection of a dexamethasone 700 μg (Ozurdex®) or anti-VEGF for at least one of the two eyes for macular edema or neovessels linked to DMLA, retinal venous occlusion, diabetic macular edema or posterior uveitis
• Phake patient, at least of the injected eye

Exclusion criteria:

- Pseudophakia of the injected eye
