ABSTRACT
Objective: This study was designed with an aim to visualize the status of the posterior portion of the eye globe of adult Saudi cataract patients with brightness mode (B-mode) ultrasound, to find out any posterior segment lesions in such preoperative cases.
Methods: A prospective study was performed between May 2014 and May 2015. A 375 preoperative cataract (184, 49.1%) males and (191, 50.9%) females between the ages from 18 to 90 years; mean age of 54 ± 0.5 years were scanned at two Radiology departments. Patients were divided into non-traumatic cataract (n = 346; 92.3%) and post-traumatic cataract (n = 29; 7.7%) groups. B-scan ophthalmic ultrasound was performed using a Hitachi (HI Vision AVIUS) ultrasound machine. The statistical package for the social sciences (SPSS) was used to analyse the results.
Results: Ultrasound revealed that vitreous haemorrhage (110, 29.3%) was the main cause of non- and post-traumatic form of cataract in preoperative adult Saudi patients. In contrast, intra-ocular tumours (6, 1.7%) and posterior vitreous detachment (1, 3.5%) were the least causes of non- and post-traumatic cataract, respectively. Preoperative adult Saudi females are more subjective to the causes of non-traumatic cataract rather than males in the same age, while males are able to develop post-traumatic cataract due to the abundance of aetiologies in comparison to females.
Conclusion: Ocular ultrasound examination in pre-operative cataract patients is a useful part of ophthalmic examination for detection, evaluation and follow-up of posterior segment pathologies that may influence the surgical strategy and the postoperative visual prognosis.
