Classification of Congenital and Early Onset Retinitis Pigmentosa

Photoreceptor cell dysplasia in two Tippler pigeons

“…The ophthalmic examination findings, electroretinographic, histopathological, and ultrastructural findings of the blind Tippler pigeons are similar to those described in children with Leber's congenital amaurosis (LCA) 48–52 . LCA is an inherited retinal dystrophy that is responsible for the severest forms of congenital blindness 53,54 and represents 5–18% of the cases of congenital blindness in children 53,55,56 .…”

Prevalence of retinitis pigmentosa and allied disorders in Denmark

“…Cases with congenital amaurosis of Leber from the simplex inheritance group included males and females equally. This fact, together with the results of Alstr0m & Olson (1957), Foxman et al (1985), and Schroeder et al (1987) gives no suspicision of a substantial female preponderance in this group.…”

A Study on Retinitis Pigmentosa as a Cause of Blindness in Patients Attending Regional Eye Hospital, Kurnool for Blind Certificate

“…Similar observations have been reported by others in RP patients. [15], [16], [17], [18] This group of patients could have congenital onset of the disease and also generally developed cataracts, as opposed to AR(R) group where cataracts were a rarity and congenital cases were not seen. The autosomal dominant patients had slowly progressive disease taking over 10-15 years.…”
