ABSTRACT
Pre-vitrectomy errors in diagnostic A & B mode ultrasound may result in affection of the surgical outcome. We have done a retrospective analysis of fifty patients who were screened by both A & B mode echography and analyzed the data which revealed that real-time kinetic echography is required for accurate interpretation of the vitreoretinal status. Besides, quantitative A scan examination also has fallacies due to the echo beam not striking the sclerochoroid complex at right angles, and a modification of this technique is suggested. Lastly old retinal detachments may not produce echo-patterns diagnostic of retinal detachments resulting in fallacious interpretation. We recommend that combined A mode and real time B-mode and often repeat echography is essential for accuracy in diagnosis.
