Parâmetros oftálmicos em cachorro-do-mato (Cerdocyon thous, Linnaeus, 1766)

Abstract

Crab-eating foxes (Cerdocyon thous) are one of the wild animals most attended in rehabilitation centers, making it imperative to extend current knowledge of morphophysiological parameters specific to the species. This study assessed the ophthalmic conditions of 16 crab-eating foxes (n=32 eyes). Eight individuals were clinically assessed, under chemical restraint, by the Schirmer tear test I (STT I), digital applanation tonometry (IOP), non-contact specular microscopy (corneal thickness, density, area and corneal endothelial cell hexagonality), ultrasound in A and B modes (biometrics, particularly axial diameter, anterior and vitreous chamber depths and lens thickness) and electroretinography (amplitudes and implicit times of a- and b-waves, in scotopic and photopic phases). Corneas, collected post mortem from another eight individuals, were evaluated histologically to determine cornea and epithelium thickness and the birefringence parameters (data regarding aggregation and orientation) of lamellar collagenous stromal fibers, using morphometry, polarized light and image analysis software. Birefringence parameters were quantified as gray average (GA) values. Regarding the STT I and IOP, mean values of 13.37±0.94 mm and 10.43±0.96 mmHg were respectively verified. The mean corneal thickness was 0.53±0.01 mm. The mean density and area values of corneal endothelial cells were respectively 2850.38±137.28 cell/mm2 and 389.00±0.17 μm2. The mean value for hexagonality was 60.06±4.66 %. Concerning biometrics, the following mean values were verified: axial diameter, 15.93±0.28 mm; anterior chamber depth, 3.29±0.14 mm; vitreous chamber depth, 6.61±0.21 mm; and lens thickness, 6.02±0.11 mm. Electroretinography in the low amplitude scotopic phase showed values for mean amplitude and b-wave implicit time (20 min adaptation) of 87.33±5.36 μV and 73.10±1.12 ms, respectively. In the high amplitude scotopic phase, the mean amplitude value ...

Cachorros-do-mato (Cerdocyon thous) figuram entre os animais selvagens mais assistidos em centros de reabilitação, tornando imperioso ampliarem-se conhecimentos sobre parâmetros morfofisiológicos próprios à espécie. Na presente pesquisa, avaliaram-se as condições oftálmicas de 16 cachorros do mato (n=32 olhos). No estudo clínico, avaliaram-se oito indivíduos, sob contenção química, à teste lacrimal de Schirmer I (TLS I), à tonometria digital de aplanação (PIO), à microscopia especular de não contato (espessura corneal, densidade, área e hexagonalidade celulares endoteliais corneais), à ultrassonografia em modos A e B (biometria, notadamente o diâmetro axial, a profundidade das câmaras anterior e vítrea, e a espessura da lente) e à eletrorretinografia (amplitudes e tempos implícitos de ondas a e b, nas fases escotóptica e fotóptica). Córneas, colhidas post mortem, de outros oito animais, foram avaliadas à histologia, quanto às espessuras da córnea e do epitélio, e aos parâmetros de birrefringência (que informam sobre agregação e orientação) de fibras lamelares colágenas estromais, empregando-se morfometria, luz polarizada e software de análise de imagens. Parâmetros de birrefringência foram quantificados como níveis de cinza médio (GA). Em relação ao TLS I e a PIO, verificaram-se valores médios de 13,37±0,94 mm e 10,43±0,96 mmHg, respectivamente. A espessura corneal média foi de 0,53±0,01mm. Relativamente às células endoteliais corneais, os valores médios de densidade e de área foram, respectivamente, de 2.850,38±137,28 cell/mm2 e de 389,00±0,17 μm2. O valor médio de hexagonalidade foi 60,06±4,66 %. Em relação à biometria, verificaram-se valores de 15,93±0,28 mm para diâmetro axial, de 3,29±0,14 mm para profundidade de câmara anterior, de 6,02±0,11 mm para espessura da lente e de 6,61±0,21 mm para profundidade da câmara vítrea. À eletrorretinografia, na fase...
