Abstract
Purpose: :
Preoperative ultrasonography is a useful diagnostic tool, especially in the assessment of posterior segment pathology in the absence of fundal view. We evaluate the value of this investigation in the management of dense cataracts.
Methods: :
A retrospective case note analysis was performed. Pre and post-operative data including documentation of light projection, the presence of a relative afferent pupil (RAPD), ultrasound diagnosis and any change to surgical management following ultrasound diagnosis were collated.
Results: :
One hundred and thirty-five patients had preoperative ultrasound performed over a 5-year period (2001-2005). Twenty-seven eyes had significant posterior pole pathology. The surgical management was not altered following the ultrasound result.
Conclusions: :
Preoperative ultrasound examination for patients with dense cataract can be used to detect pathologies that may influence the surgical strategy and the postoperative visual prognosis. In our review, ultrasound diagnosis had no influence on the surgical strategy other than warn of guarded prognosis. Our recommendation is to check projection in all quadrants, assess pupillary response and obtain past ocular history before requesting an ultrasound exam.
