Phenotype                        Clinical characteristics
--------------------------------   -----------------------------------------------
1. Stargardt maculopathy           Oval-shaped RPE irregularity and thinning,
                                   "beaten bronze" reflexes, and perifoveal
                                   yellow-grey flecks

2. Stargardt-flavimaculatus and    Abundant fish-tail-like yellowish flecks
   Fundus flavimaculatus           outside the  foveal  area with foveal
                                   atrophy of RPE

3a. Central and peripheral RPE-    Ill-defined macular RPE-atrophy with
    choriocapillaris atrophy       coarse hyperpigmentation and peripheral
                                   atrophic RPE speckles and/or webs

3b. Atypical RP (choroidoretinal   Diffuse choroidoretinal dystrophy with
    photoreceptor dystrophy)       narrow arterioles, constricted visual fields,
                                   and severely reduced full-field ERG rod
                                   and cone responses

4.  Cone-rod dystrophy             Foveal RPE atrophy with early predominant
                                   cone affection of the full-field ERG

5a. Bull's eye maculopathy         Foveal bull's eye lesion without flecks,
                                   varied involvement of peripheral RPE atrophy,
                                   and normal or subnormal full-field ERG

5b. Unspecified maculopathy        Foveal RPE atrophy without flecks and
                                   without significant ERG changes
