PURPOSE: To evaluate the accuracy of the Smith method, van Herick technique, and Shaffer grading system, using a slit-lamp biomicroscope and gonioscope that measure anterior chamber depth (ACD), peripheral chamber depth (PCD), and angle width. METHODS: The anterior chamber of 94 eyes of 53 subjects was evaluated by slit-lamp examination with a gonioscope. An A-scan was carried out on all of the subjects, but ultrasound biomicroscope (UBM) was performed on only 42 of 94 eyes. Slit-lamp biomicroscope-assisted measurements, such as ACD, PCD, and angle width, were compared with those by A-scan and UBM. RESULTS: The correlations among ACD measurements, obtained by the Smith method, and those obtained using A-scan (r=0.673, p<0.001) and UBM (r=0.824, p<0.001) were statistically significant. The mean PCD, measured by van Herick technique, was 14.01+/-15.04 %, and its correlation with that of UBM was statistically significant (r=0.706, p<0.001). In addition, the correlation between the mean angle width, measured by Shaffer grading system and by UBM, was also statistically significant (r=0.853, p<0.001). CONCLUSIONS: Assessments of the anterior segment, using a slit-lamp biomicrosope and a gonioscope, are comparable to those of A-scan and UBM measurements and are, therefore, useful for evaluation of the anterior chamber.

Journal of the Korean Ophthalmological Society 1987;28(1):59-65
Intraocular lens power was calculated from data of axial length, corneal curvature, and anterior chamber depth in 112 eyes which underwent IOL implant surgery. Postoperative refractions of 112 eyes were analyzed into three groups such as the group of which constant A is 116.2, the group of which constant A is 116.8, and TI-59 system group. The results were as follows; 1. The A constant derived from retrograde analysis in our 112 cases was 116.2. In the cases of the constant A 116.2, error of predicted required spectacle lens power was -0.16D +/- 0.89 in relative average, 0.67D +/- 0.57 in absolute average. Using the standard formula described by Hoffer, the accuracy of IOL power calculation by the constant 116.2 was 76.1% +/- 1.0D / 97.4% +/- 2.0D / +2.42 to -2.11D. 2. The specific constant A of intraocular lenses inserted in our hospital was 116.8. In the cases of the constant A 116.8, error of predicted required spectacle lens power was -0.39D +/- 0.88 in relative average, 0.75D +/- 0.60 in absolute average. Using the standard formula described by Hoffer, the accuracy of IOL power calculated by the constant A 116.8 was 72% +/- 1.0D / 96% +/- 2.0D / +2.34 to -2,50D. 3. In TI-59 system of IOL power calculation, error of predicted required spectacle lens power was -0.12D +/- 1.0D in relative average and 0.75D +/- 0.66 in absolute average. Using the staudard formula described by Hoffer, the accuracy of IOL power calculation in this method was 73% +/- 1.0D / 91.5% +/- 2.0D / +2.77 to -2.31D. 4. There was a significant difference between the error of the A constant 116.2 and that of 116.8(P. 0.05), but wasn't between the error of the A constant 116.2 and that of TI-59 system. 5. In the case of axial length 21mm +/- 0.5, the IOL power calculation by the A constant 116.2 was the most accurate among three groups.

6.A case of Angiostrongylus cantonensis invaded into the ocular anterior chamber.
Journal of Practical Medicine 2002;435(11):66-68
A female patients with ages of 3 admitted urgently in the Institute of ophthalmology in 12/2001 due to the a white spot in the right eye. The examination, paraclinical tests diagnosed as a worm invaded into the ocular anterior chamber that damaged the iris. The patients operated emergency after 3 hours of hospitalization. The results have shown that the causative agent was Angiostrongylus wantonness (male) with opaque, length of 15 mm its stem covered by smooth peal, circle head and obvious teeth.

To investigate the relationship of the density change of lens nucleus and cortex with anterior chamber depth and lens thickness, we measured the anterior chamber depth, density and length of lens nucleus and cortex of 312 eyes with a Scheimpflug camera. The mean values of density of lens nucleus and cortex were 108.45+/-46.33CCT and 27.74+/-13.76CCT, respectively. The mean values of the thickness for both were 2.85+/-0.54mm and 1.29+/-0.46mm, respectively. The mean value of anterior chamber depth was 2.93+/-0.49mm. The densities of lens nucleus and cortex were increased significantly with aging, but lens thickness and anterior chamber depth were decreased. The value of anterior chamber depth changes and lens thickness changes were more rapid especially in the 5th and 7th decades compared with other groups(P<0.01), and more rapaid in the density group(100~150CCT) than other group in changing densities(P<0.05), and they were highly correlated with anterior cortex, posterior cortex, nucleus in order at each portion of lens. Both anterior chamber depth changes and lens thickness changes were more rapid in the lens cortex than those in the lens nucleus.

Journal of the Korean Ophthalmological Society 1992;33(11):1060-1064
The biometric analysis of the normal aged eye with photodocumented method (using EAS-lOOO Scheimpflug camera) was performed in 109 eyes. We measured anterior chamber depth, corneal thickness, corneal radius, lens thickness and biometric lens analysis according to the age. The lens thickness increased annually (O.O1mm) with age and the anterior chamber depth reversely decreased. The biometric analysis can provide normal critariae values about the effect of anticatar acto us drugs in long-term follow up study and the relationships between normal aged lens and highly risk groups in the cataract prevalence study.

PURPOSE:We compared the measurements of corneal thickness and anterior chamber depth (ACD) using three different methods Orbscan, Pentacam and ultrasound pachymetry. METHODS: In healthy volunteers, central corneal thickness was measured with Orbscan, Pentacam and ultrasound pachymetry. Estimation of peripheral corneal thickness and ACD were done by Orbscan and Pentacam. All results were compared statistically. RESULTS: The mean central corneal thickness of 64 eyes measured by Orbscan, Pentacam and ultrasound pachymetry were 509.1+/-61.0 microm, 539.2+/-51.7 microm and 527.4+/-48.3 microm, respectively. There were statistically significant differences in the results among the three methods (repeated-measures analysis of variance (ANOVA), p<0.05). There were significant correlations between the ultrasonic pachymetry, the Orbscan and the Pentacam (Pearson correlation, r>0.90, p<0.05). The temporal and nasal peripheral corneal thicknesses were thinner in the Pentacam than in the Orbscan (paired t-test, p<0.05). The superior and inferior corneal thickness and ACD were not significantly different. CONCLUSIONS: The results of the three instruments have significant correlations with each other, so all methods are clinically useful.
