“…Kim et al 16 found a high negative correlation (r Z À0.865) between K readings (in diopters) and the sulcus diameter; however, the study was limited by the number of patients (n Z 14), that accommodation was not excluded, and that most of the patients were highly myopic. In our study of pseudophakic eyes, K readings and AL showed a weak correlation with sulcus diameter.…”

“…Several studies [15][16][17][18][19] have evaluated the relationship between WTW and STS diameters in an effort to select adequately sized posterior phakic IOLs. Using different devices to measure the STS and the WTW, they showed a weak correlation (r Z 0.406 to r Z 0.597) between these 2 values.…”

“…Surprisingly, to our knowledge, no data on the STS diameter in pseudophakic patients have been published. In contrast, many studies [15][16][17][18][19][20][21] report the sulcus anatomy in young phakic patients with the goal of optimizing the sizing and vault of posterior chamber phakic IOLs. Other studies 22,23 report the sulcus anatomy in aphakic eyes with a scleral-fixated IOL to evaluate and optimize the IOL position.…”

DESIGN: Case series. METHODS:In pseudophakic eyes, the axial length (AL) and horizontal WTW were measured by the IOLMaster device. Cross-sectional images were obtained with a 50 MHz ultrasound biomicroscope on the 4 meridians: vertical, horizontal (180 degrees), temporal oblique, and nasal oblique. Sulcusto-sulcus (STS), angle-to-angle (ATA), and sclera-to-sclera (ScTSc) diameters were measured. The IOL optic diameter (6.0 mm) served as a control. To test reliability, optic measurements were repeated 5 times in a subset of eyes. RESULTS:The vertical ATA and STS diameters were statistically significantly larger than the horizontal diameter (PZ.0328 and PZ.0216, respectively). There was no statistically significant difference in ScTSc diameters. A weak correlation was found between WTW and horizontal ATA (r Z 0.5766, P<.0001) and between WTW and horizontal STS (r Z 0.5040, PZ.0002). No correlation was found between WTW and horizontal ScTSc (r Z 0.2217, PZ.1217). CONCLUSIONS:The sulcus anatomy had a vertical oval shape with the vertical meridian being the largest, but it also had variation in the direction of the largest meridian. The WTW measurements showed a weak correlation with STS. In pseudophakic eyes, Soemmerring ring or a bulky haptic may affect the ciliary sulcus anatomy.

“…However, some studies [4][5][6][7] found no correlation between WTW diameter and ciliary sulcus diameter, and others found a WTW diameter larger than the ciliary sulcus diameter. 5,8 Choi et al 3 found high vault (O750 mm) and low vault (!250 mm) in 17.6% and 23.5% of eyes, respectively, when determining pIOL length using WTW diameter. These conflicting results could be due to individual variation in WTW diameter and ciliary sulcus diameter and the repeatability performance of the measuring device.…”

“…[4][5][6][7][8][9][10][11][12] Despite efforts to improve predictability of vault following ICL implantation, it remains poor; the reasons for this are multiple. 5,[13][14][15][16][17][18][19][20][21][22][23] High-frequency ultrasound biomicroscopy (UBM) with a wide scanning field has enabled direct measurement of horizontal sulcus-to-sulcus (STS) diameter. Poor correspondence (г<0.50) between the horizontal WTW and STS measure has since been reported, however the width of the limits of agreement (LoA) reported between horizontal WTW and STS measures is similar to repeatability limits of STS estimates.…”

PURPOSE:To assess the agreement and repeatability of horizontal white-to-white (WTW) and horizontal sulcus-to-sulcus (STS) diameter measurements and use this data in combination with available literature to correct for inter-device bias in pre-operative implantable collamer lens (ICL) size selection. DESIGN: Inter-instrument reliability and bias assessment study. METHODS: A total of 107 eyes from 56 patients assessed for ICL implantation at our institution were included in the study. This was a consecutive series of all patients with suitable available data. The agreement and bias between WTW (measured with the Pentacam and BioGraph devices) and STS (measured with the HiScan device) were estimated. RESULTS: The mean spherical equivalent was -8.93D ± 5.69D. The BioGraph measures of WTW were wider than those taken with the Pentacam (bias= 0.26 mm, p<0.01), and both horizontal WTW measures were wider than the horizontal STS measures (bias >0.91 mm, p<0.01). The repeatability (Sr) of STS measured with the HiScan was 0.39 mm, which was significantly reduced (Sr=0.15 mm) when the average of two measures were used. Agreement between the horizontal WTW measures and horizontal STS estimates when bias was accounted for was г=0.54 with the Pentacam and г=0.64 with the BioGraph. CONCLUSIONS: Large inter-device bias was observed for WTW and STS measures. STS measures demonstrated poor repeatability, but the average of repeated measures significantly improved repeatability. In order to conform to the Federal Drug Administration's accepted guidelines for ICL sizing clinicians should be aware of and account for the inconsistencies between devices.3

Correlation between ciliary sulcus diameter measured by 35 MHz ultrasound biomicroscopy and other ocular measurements

Abstract: Mean corneal curvature was significantly and negatively correlated with horizontal sulcus diameter. The derived regression formula based on mean corneal curvature measurements may help predict sulcus diameters for proper sizing of posterior chamber phakic intraocular lenses.
