Cockatiel (Nymphicus hollandicus) — Cryptophthalmos (hereditary; OMIA-verified species predisposition)
Source: first-hand OMIA (University of Sydney) species-specific hereditary-disorder record, saved verbatim to source_file; every claim below is a C1 byte-substring of it.
Claims
Species: Cockatiel (Nymphicus hollandicus)Disorder: CryptophthalmosSummary: Buyukmihci et al. (1990): "Four unrelated cockatiels had various degrees of maldevelopment of the eyelids. Only 1 eye of the 8 was normal. The condition had features compatible with ankyloblepharon or cryptophthalmos. ... Anecdotal information along with our findings suggest that this condition, although uncommon, is widespread in the cockatiel population in the United States."
