Eye conditions in dogs including cataracts, progressive retinal atrophy, glaucoma, and entropion cause significant pain and welfare impairment if untreated.
Ocular disease causes a spectrum of welfare impacts from chronic mild discomfort to acute severe pain. Entropion causes constant corneal irritation and pain. Glaucoma causes intense pressure-related pain and rapid vision loss. PRA causes progressive loss of vision affecting spatial awareness and confidence. Cataracts can cause complete blindness. Welfare-responsible breeding uses genetic testing to reduce inherited eye conditions. Prompt surgical management of treatable conditions dramatically reduces suffering.
