A-scan ultrasonography

In the present study 50 patients (50 eyes) with equal number of cases and controls are evaluated with detailed history, ocular examination and biometric data was taken from both the groups using A-scan ultrasonography.

A-scan ultrasonography by (Quantel Medical biometer) was done to measure ACD (anterior chamber depth).

Anterior chamber depth measurement with a-scan ultrasonography, Orbscan II, and IOLMaster.

Although conventional A-scan ultrasonography is the gold standard method for measuring ACD, noncontact methods and devices such as partial coherence interferometry, slit-scanning topography, anterior segment optical coherence tomography and Scheimpflug imaging have become widely used in clinics in recent years.

Because the IOLMaster does not always provide reliable ACD measurements in pseudophakic eyes, ACD was measured using A-scan ultrasonography (Eye Cubed[TM], Ellex, Adelaide, Australia).

Anterior chamber depth and ocular biometry were measured with A-scan ultrasonography (Quantel Medical Echograph, B-scan Vplus/biovision).
