Brief summary
Clinical trial investigating the role of hyperspectral imaging in the management of patients undergoing standard clinical treatment for naive neovascular choroidal membranes in age-related macular degeneration.
Detailed description
Observational trial of patients with choroidal neovascular membranes treated with Lucentis. Exploration and validation of a new form of retinal imaging called hyperspectral imaging. Inclusion: Patients meet eligibility criteria other than FFA diagnosis and who are diagnosed with suspected exudative CNV on the OCT. (n=100 eyes) Procedure: Monthly doses of Lucentis. OCT scans will be taken prior to each injection. HSI image taken at baseline and at the 9-month time point. Time frame: 6 months recruitment + 12 months follow-up + 6 months analysis. All recruited patients will receive monthly doses of Lucentis as per the CMBS-approved protocol to allow comparison with other published studies. Lucentis will be administered in accordance with published standards of practice. OCT scans will be taken prior to each injection. HSI image will be taken at baseline, three months and 9-month time points
Interventions
DEVICEHyperspectral imaging
Hyperspectral retinal images will be taken at baseline (before treatment with Lucentis) and then at 3 and 9 months after treatment.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Hyperspectral image characteristics that predict response of choroidal neovascularisation to Lucentis | 3-9 months | Hyperspectral images will be analysed to define specific characteristics that identify which types of choroidal neovascularisation will respond to Lucentis. Responsive patients will be differentiated from non-responders and distinguishing image features will be identified. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Specific spectral signature for identification of exudative AMD | 3-9months | Spectral bands of the HSI containing the most predictive information for diagnosis and treatment response will be characterised. |
