Mean spherical equivalent refraction ranged from +5.50 to \u22127.00 diopters. Angle-to-angle and iris pigment end-to-iris pigment end distances were measured in all cases three times consecutively using two technologies: optical coherence tomography (OCT) and very high-frequency ultrasonography. Sulcus-to-sulcus diameter was additionally obtained by ultrasonography. Correlation, linear regression, intrasession, and interchangeability analysis between parameters was performed.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Results:<\/jats:title>\n            <jats:p>\n              Mean sulcus-to-sulcus diameter was 11.92\u00b10.80 mm. Mean angle-to-angle distance was 12.14\u00b10.52 mm for ultrasonography and 12.23\u00b10.59 mm for OCT. Mean iris pigment end-to-iris pigment end distance was 12.18\u00b10.51 mm for ultrasonography and 12.29\u00b10.61 mm for OCT. No statistically significant differences were found among these anatomical parameters (unpaired Student\n              <jats:italic>t<\/jats:italic>\n              test, all\n              <jats:italic>P<\/jats:italic>\n              &gt;.10). Statistically significant correlations were found between sulcus-to-sulcus diameter and angle-to-angle distance and between sulcus-to-sulcus diameter and iris pigment end-to-iris pigment end distance for both imaging techniques. For ultrasonography, range of agreement was 0.90 mm between sulcus-to-sulcus diameter and angle-to-angle distance and 0.74 mm between sulcusto-sulcus diameter and iris pigment end-to-iris pigment end distance. These ranges increased to 1.22 mm and 1.14 mm, respectively, for OCT measurements.\n            <\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Conclusions:<\/jats:title>\n            <jats:p>Angle-to-angle and iris pigment end-toiris pigment end distances are correlated with sulcus-to-sulcus diameter, but they cannot be used as equivalent parameters.<\/jats:p>\n            <jats:p>\n              [\n              <jats:italic>J Refract Surg.<\/jats:italic>\n              2009;25:1017\u20131025.]\n            <\/jats:p>\n          <\/jats:sec>","DOI":"10.3928\/1081597x-20091016-08","type":"journal-article","created":{"date-parts":[[2009,11,18]],"date-time":"2009-11-18T22:41:55Z","timestamp":1258584115000},"page":"1017-1025","source":"Crossref","is-referenced-by-count":19,"title":["Ciliary Sulcus Diameter and Two Anterior Chamber Parameters Measured by Optical Coherence Tomography and VHF Ultrasound"],"prefix":"10.3928","volume":"25","author":[{"given":"David P.","family":"Pi\u00f1ero","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ana Bel\u00e9n Plaza","family":"Puche","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jorge L.","family":"Ali\u00f3","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"2308","reference":[{"key":"e_1_3_2_2_2","doi-asserted-by":"publisher","DOI":"10.3928\/1081-597X-20071101-02"},{"key":"e_1_3_2_3_2","doi-asserted-by":"publisher","DOI":"10.3928\/1081-597X-20070201-07"},{"key":"e_1_3_2_4_2","doi-asserted-by":"publisher","DOI":"10.3928\/1081-597X-20050301-05"},{"key":"e_1_3_2_5_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jcrs.2004.04.051"},{"key":"e_1_3_2_6_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0161-6420(03)00405-6"},{"key":"e_1_3_2_7_2","doi-asserted-by":"publisher","DOI":"10.3928\/1081-597X-20021101-06"},{"key":"e_1_3_2_8_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0161-6420(00)00221-9"},{"key":"e_1_3_2_9_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0886-3350(00)00543-5"},{"key":"e_1_3_2_10_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0161-6420(99)90103-3"},{"key":"e_1_3_2_11_2","doi-asserted-by":"publisher","DOI":"10.3928\/1081-597X-19980501-12"},{"key":"e_1_3_2_12_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.survophthal.2005.08.011"},{"key":"e_1_3_2_13_2","doi-asserted-by":"publisher","DOI":"10.1097\/00055735-200408000-00012"},{"key":"e_1_3_2_14_2","doi-asserted-by":"publisher","DOI":"10.1097\/01.cco.0000188624.54743.c7"},{"key":"e_1_3_2_15_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jcrs.2004.03.035"},{"key":"e_1_3_2_16_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jcrs.2004.07.018"},{"key":"e_1_3_2_17_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jcrs.2003.10.039"},{"key":"e_1_3_2_18_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jcrs.2004.11.059"},{"key":"e_1_3_2_19_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0886-3350(02)02040-0"},{"key":"e_1_3_2_20_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.ophtha.2004.09.019"},{"key":"e_1_3_2_21_2","doi-asserted-by":"publisher","DOI":"10.3928\/1081-597X-20040901-08"},{"key":"e_1_3_2_22_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jcrs.2006.08.023"},{"key":"e_1_3_2_23_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0140-6736(86)90837-8"},{"key":"e_1_3_2_24_2","doi-asserted-by":"publisher","DOI":"10.1136\/bmj.313.7048.41"},{"key":"e_1_3_2_25_2","doi-asserted-by":"publisher","DOI":"10.3928\/1081-597X-20021101-03"},{"key":"e_1_3_2_26_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jcrs.2003.10.041"},{"key":"e_1_3_2_27_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0886-3350(00)00830-0"},{"key":"e_1_3_2_28_2","doi-asserted-by":"publisher","DOI":"10.3928\/1081597X-20090201-03"},{"key":"e_1_3_2_29_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.ophtha.2006.12.018"},{"key":"e_1_3_2_30_2","first-page":"469","article-title":"Ultrasound biomicroscopy of the anterior segment","volume":"67","author":"Liebmann JM","year":"1996","unstructured":"Liebmann JM, Ritch R.
