The long-term prognosis for patients with<unk>  is widely variable and depends on the age of onset and genetic alleles. The majority of patients will progress to legal blindness, which means that central reading vision will be lost. However, perimetry and microperimetry studies indicate that the peripheral light sensitivity is preserved over a long time in a significant fraction of all patients (i.e., >50%).<unk>  has no impact on general health and life expectancy is normal. Some patients, usually those with the late-onset form, can maintain excellent visual acuities for extended periods and are therefore able to perform tasks such as reading or driving.
