Original Pupillometry in Patients with Leber Congenital Amaurosis: Feasibility Study and Residual Retinal Cell Function
Radwan Ajlan , Leah Wood, Irma Lopez, Ayesha Khan, and Robert K. Koenekoop*
Leber Congenital Amaurosis (LCA) (OMIM 204000) is a devastating, hereditary photoreceptor disease. It is estimated to be responsible for 5% of all inherited retinal disease and characterized by severe visual impairment at or near birth, wandering nystagmus, abnormal pupillary responses (amaurotic pupils), a severely decreased or absent electroretinogram (ERG), and high refractive errors. At least twenty retinal genes have currently been associated with LCA, en-coding retinal proteins that participate in a wide variety of retinal functions.

Presbyopia is defined as the loss of power of lens accommodation related to age. It causes an inability of the eye to focus on near objects and images clinically reflected by a gradual decline of near vision. Its prevalence in countries with low and middle income is uncertain because most studies of refractive errors in these countries have been limited to distance vision.
