Purpose:
|
Evaluation of anterior chamber depths measured with OrbScan and Pentacam compared with the Smith method results.
|
|
Methods:
|
Smith method developed in 1979 ,with an accuracy of approximately 0.1 mm(Ref: Smith RJ. A new method for the estimation of the depth of the anterior
chamber. Br J Ophthalmol 1979;63:215-20)is a reliable way to measure of ACD only with help of slit lamp. In this study 102 phakic eyes (PRK candidates) were imaged with both OrbScan and Pentacam and finally ACD was measured thru Smith method. ACD measured with Smith method was presumed as the standard and so was compared with ACDs of the 2 imaging instruments. Contraindicated cases for PRK and pseudophakic eyes have been excluded from the study.

|
Results:
|
Mean age of the patients is 35.2+_14.8 yrs/old including 56 M(54.9%)and 46 F(45.09%).Correlation of ACD measured thru Smith method with Orbscan and Pentacam are r=0.958 and r=0.942 respectively and so Orbscan results can be more useful in procedures relying on ACD.
|
|
Conclusion:
|
ACDs measured with OrbScan is more accurate than Pentacam and so can be more useful in some surgery procedures relying ACD such as phakic IOLs or in cycloplegia contraindications.
