Laser development in opthalmology is ever more using extended sources or optics producing large retinal images. Such applications require a retinal dosimetry for minimizing the possiblity of damage. Some biological data show that present limit values for large image sizes are not safe. A formulation is proposed allowing one to specify an appropriate retinal dosimetry suitable for the use for very large images.
