(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.\"`\n## Evidence (references)\nDerived from OMIA database dump (omia.xml, local); structured field, not verbatim prose.
