Ophthalmic parameters in adult Pomeranian dogs

ABSTRACT The objective of this study was to establish ophthalmic parameters in the Pomeranian dog breed. Schirmer tear test (STT), breakup time (TBUTT), Jones (JT), aesthesiometry, biomicroscopy, tonometry, non-contact specular microscopy (SM), ophthalmoscopy and ultrasonography (US) were carried out 48 eyes 24 male female dogs from a breeding kennel. Descriptive statistics applied for data analysis. Means standard errors found STT, TBUT, JT, esthesiometry tonometry 24.310±0.448mm/min, 14.570±0.406s., 8.420±1.571min, 3.667±0.157cm 17.960±0.697mmHg, respectively. For 43.75% presented caruncle trichiasis, 25% chromodacryorrhea, medial entropion 10,42% distichiasis. SM showed endothelial cells density 1958.285±36.760 cells/mm². hexagonality, area central corneal thickness 62.229±2.183%, 519.231±9.853mm², 0.567±0.006mm, Ophthalmoscopy pattern described other breeds. Amelanotic fundus reported 8.33% eyes. US means axial length eyeball, lens thickness, anterior vitreous chamber depth 16.859±0.148mm, 6.651±0.081mm, 2.673±0.091mm 7.485±0.101mm. Mild changes lacrimal evaluation influenced by eyelid STT type I. Increased sensitivity observed
