Detaljeret beskrivelse
To date, no functional imaging modality has been validated to assess the level angiogenic activity of choroidal neovascularization in AMD, while the therapeutic use of antiangiogenic agents is almost systematically in the form of intraocular injections.
The therapeutic response is observed anatomically and functionally only after 6 months of treatment. Several arguments in the literature suggest that the therapeutic response occurs earlier at the molecular level, as soon as the induction phase is complete (after 3 months of treatment). The main objective of this pilot study is to evaluate the ability of 68Ga-NODAGA-RGD PET imaging to demonstrate, in patients with unilateral AMD, a molecular therapeutic response to intraocular antiangiogenic injections at the end of the first phase. induction (after 3 months of treatment).

ANDET: PET at 68Ga-NODAGA-RGD
The first PET scan will be performed within a maximum of one month following the initial ophthalmologic assessment including OCT and measurement of visual acuity (M0);

Measurement of the signal intensity ratios of the AMD eye / contralateral eye TEP (SUVmax) signal
Tidsramme: 7 måneder
|
Images from the 68Ga-NODAGA-RGD PET scan will be interpreted without results of other examinations and clinical history. Two experienced nuclear physicians unfamiliar with the results of the initial balance sheet examinations will complete a grid listing the quantification of the 68Ga-NODAGA-RGD (SUVmax) signal measured in each eye of each patient. The signal intensity ratios of the AMD eye / contralateral eye TEP (SUVmax) signal at M0 and M4 will be compared by a comparison test of paired averages. |
