AB  - OBJECTIVE: To describe and to establish normative data for the foveae of diurnal 
      birds of prey using spectral-domain optical coherence tomography (SD-OCT). 
      METHODS: All animals (9 red-tailed hawks, 3 Cooper's hawks, 3 American kestrels, 
      1 sharp-shinned hawk, and 1 broad-winged hawk) had an ophthalmic examination 
      performed with slit lamp biomicroscopy and indirect ophthalmoscopy. Following 
      ophthalmic examination, SD-OCT was performed in each eye that had a visible 
      fundus and normal fovea on SD-OCT. Temporal foveae depth, central foveae depth, 
      pecten-temporal foveae distance, and pecten-central foveae distance (PCFD) were 
      measured using SD-OCT. Differences in measured outcomes between species were 
      determined using generalized linear mixed effects models. RESULTS: The central 
      foveae (mean +/- SD) displayed a small but significant depth variation between 
      species (P = .002) and was deepest in red-tailed hawks (293 +/- 16 microm), followed by 
      American kestrels (260 +/- 12 microm), broad-winged hawks (256 +/- 16 microm), Cooper's hawks 
      (250 +/- 9 microm), and sharp-shinned hawks (239 +/- 16 microm). The temporal foveae were 
      shallower than the central foveae in all species tested, and there was a 
      significant variation between species (P < .001). The temporal foveae (mean +/- SD) 
      were deepest in American kestrels (137 +/- 8 microm), followed by red-tailed hawks 
      (129 +/- 3 microm), broad-winged hawks (59.5 +/- 3.5 microm), Cooper's hawks (20.3 +/- 6.4 microm), 
      and sharp-shinned hawks (17.5 +/- 0.7 microm). Pecten-temporal foveae distance was 
      approximately 30% shorter than PCFD in all species. There were no differences in 
      the parameters tested between the eyes within each species (P >/= .47). CONCLUSION: 
      Normative foveae SD-OCT data were obtained in four species of diurnal birds of 
      prey. Further studies are warranted to provide structural and functional 
      information regarding normal and pathologic changes that can affect the foveae.
