A total of 29 eyes from 29 client-owned dogs with normal intraocular pressure (IOP) were scanned at the limbus using SD-OCT, UBM, and gonioscopy. ICA and angle opening distance (AOD) were measured from the obtained images of SD-OCT and UBM, and gonioscopy images were analyzed using the ICA grade and ZibWest angle index. The mean ICA and AOD for SD-OCT and UBM were 28.87 ยฑ 5.78ยบ and 656.94 ยฑ 201.37 ฮผm and 29.00 ยฑ 6.38ยบ and 849.79 ยฑ 257.12 ฮผm, respectively. The mean difference in ICA between SD-OCT and UBM was 0.13o with a 95% limit of agreement (LoA) span of 15.1o, which showed positive agreement, whereas the mean difference in AOD between SD-OCT and UBM was 192.85 ฮผm with a 95% LoA span of 912.21 ฮผm, which showed negative agreement. The Pearson correlation coefficient of the ICA of SD-OCT and ZibWest indices of gonioscopy was 0.574, indicating strong agreement, and the Pearson correlation coefficient of the UBM and gonioscopy was 0.43, indicating moderate agreement. The inter-device agreements for ICA measurement of SD-OCT, UBM, and gonioscopy were good, such that SD-OCT could be considered an alternative option to screen the narrowing of the filtration angle in clinical settings due to its many benefits, such as the non-contact method and easy handling. Early detection of ICA narrowing may provide information on patients who need early therapeutic interventions.๋ณธ ์—ฐ๊ตฌ๋Š” ์ดˆ์ŒํŒŒ์ƒ์ฒดํ˜„๋ฏธ๊ฒฝ(UBM), ๋น›๊ฐ„์„ญ๋‹จ์ธต์ดฌ์˜์žฅ์น˜(SD-OCT), ๊ทธ๋ฆฌ๊ณ  ์šฐ๊ฐ๊ฒฝ์„ ํ†ตํ•˜์—ฌ ๊ฒ€์‚ฌํ•œ ํ™์ฑ„๊ฐ๋ง‰๊ฐ์„ ์ธก์ •ํ•˜๊ณ  ๊ฒ€์‚ฌ๋ฒ• ์‚ฌ์ด์˜ ์ƒ๊ด€์„ฑ์„ ๋น„๊ตํ•จ์œผ๋กœ์จ ์ƒ๋Œ€์ ์œผ๋กœ ์‚ฌ์šฉํ•˜๊ธฐ ์šฉ์ดํ•œ SD-OCT๊ฐ€ ๊ฐ€์ง€๋Š” ์ง„๋‹จ์  ์˜์˜๋ฅผ ํ™•์ธํ•˜๊ธฐ ์œ„ํ•œ ๊ฒƒ์ด๋‹ค. 2021๋…„ ์„œ์šธ๋Œ€ํ•™๊ต ๋™๋ฌผ๋ณ‘์›์— ๋‚ด์›ํ•œ ๊ฐœ 29๋งˆ๋ฆฌ์˜ ์ •์ƒ ์•ˆ์•• ๋ˆˆ์„ ๋Œ€์ƒ์œผ๋กœ ์ง„ํ–‰ํ•˜์˜€๋‹ค. 19๋งˆ๋ฆฌ๋Š” ๋ฐ˜๋Œ€์ชฝ ๋ˆˆ์—์„œ ๋…น๋‚ด์žฅ ์ง„๋‹จ๋ฐ›์€ ํ™˜์ž์˜€์œผ๋ฉฐ 10๋งˆ๋ฆฌ๋Š” ์ •์ƒ ๋ˆˆ์˜ ํ™˜์ž์˜€๋‹ค.
