| dc.description.abstract | The present work “Studies on oculometry with reference to skull conformation and age in dogs” was carried by selecting the normal eyes after assessing the eyes with general and clinical ophthalmological examination. Transcorneal direct contact for A scan and immersion method for B scan was carried under topical anesthesia in 54 dogs and yielded in good data for oculometry. Based on skull conformation (Dolichocephalic, Mesaticephalic and Brachycephalic Breeds) and age (Young (0-9 months); Middle age (1-6 years) and Old: above 7 years) dogs were divided for analysis following oculometry. On A scan, anterior chamber depth, lens thickness, vitreous chamber depth and globe axial length of right and left eyes were 3.03 ±0.10 and 3.10±0.14 ; 2.62±0.21 and 2.32±0.22 ; 14.83±0.33 and 14.96±0.31 and 20.48±0.22 and 20.49±0.22 , respectively while the measurements on B scan were 2.92±0.08 and 2.84±0.09 6.87±0.08 and 6.84±0.09 ; 8.84±0.09 and 8.86±0.08 and 19.60±0.25 and 19.52±0.26 respectively. A and B-mode ultrasonography were easy, practical, safe and useful techniques for ocular biometry in dogs. There was a phase of growth of the ocular components in the age group of 0-9 months in all the breeds with different skull conformation. Skull size do not interfere with ocular biometry measurements in above one year aged dogs. There was no significant difference between the ocular biometric measurements of left and right eyes, at different age. Anterior chamber length and lens thickness increased as age advances with B scan however both the values are different in A and B mode scanning procedure. A scan reveals clear axial globe length and B scan measured lens thickness, vitreous chamber depth and globe axial length with more reliability. To conclude that the B scan procedure showed to be better as it recorded all the ocular components accurately with clear image. The A scan procedure was simple to perform and recorded globe axial length accurately and unable to record the values of lens thickness and vitreous chamber depth precisely. B scan can be a useful tool for ocular biometry due to its accuracy and the reliability with an advantage of effective role in recording the ocular components architecture for diagnosis. | |
