Congenital Cataract in a Cynomolgus Monkey

Clinical presentation, treatment, and genetic and histopathological analysis of juvenile cataracts and secondary glaucoma in a rhesus macaque (Macaca mulatta)

“…Although uncommon, congenital and juvenile cataracts have been reported in NHPs 4–8 . In our presented case, the cataracts were classified as juvenile cataracts based on the age of the primate at the time of diagnosis.…”

“…In humans, congenital and juvenile cataracts can have genetic origin or can be associated with infectious diseases, metabolic disorders, or trauma 1,2 3 ; however, spontaneous congenital or juvenile cataracts in NHPs are rare, with only a few cases reported 4–8 . In rhesus macaques ( Macaca mulatta ), the incidence of cataracts increases with age, 9 but secondary glaucoma from lens‐induced uveitis has not been described in this species, and it is rarely reported in other NHP 5 …”
