Ellex - Difficult A Scan with Retinal Detachment

Case 4 Difficult A Scan with Retinal Detachment	Preoperative measurement accuracy is determined by several factors: echo patterns of consistent and high quality, use of proper measurement mode and caliper positions for selection of ultrasound velocities, and interpretation by a trained biometrist. Dense cataracts, or the presence of vitreous or macular pathology signal the examiner by their echo patterns. Even in the presence of these pathologies, accurate ultrasound biometry may be performed on ALL patients. Detection and interpretation of abnormal echoes leads to a more accurate prediction of surgical and refractive outcome.
