Keratometry, biometry, and prediction of intraocular lens power in adult tigers (Panthera tigris).

Objective: To calculate the necessary pseudophakic intraocular lens (IOL) power to approximate emmetropia in adult tigers.

Animals: 17 clinically normal adult tigers.

Procedures: 33 eyes of 17 clinically normal adult tigers underwent routine ophthalmic examination and B-scan ultrasonography while anesthetized for unrelated procedures.

Prevalence and type of ocular disease in a population of aged captive nondomestic felids.

Objectives: Report of prevalence and type of ocular disease in a captive population of nondomestic felids.

Methods: Medical records of 202 cats from 1993 to 2018 were reviewed. Species, age at diagnosis, sex, ocular examination abnormalities, systemic/physical examination abnormalities, type of examination (visual, sedated, or anesthetized), ocular structures affected, other diagnostics, therapy, and resolution of ocular disease were recorded.
