“…Abnormal USG findings were observed in 78 eyes (12.5%). Commonest were retinal detachment (4%) and posterior vitreous detachment (2%) followed by poseriorstaphyloma (1.6%) and vitreous haemorrhage (0.8%).. Mendes et al (2009), who studied sonographic findings in patients with cataract and reported vitreous opacities to be the most common abnormality (12.1%). Retinal detachment the most common finding on USG is attributed to fluid in the vitreous cavity which passes through holes or tears directly in the retina (subretinal fluid) and separates the retina from the underlying pigmented retinal epithelium (Wilkinson, 2014).…”

“…India is committed to the goal of elimination of avoidable blindness by 2020 (Murthy et al, 2008). Cataract has been defined as an opacity of any part of the lens (Mendes et al, 2009).

Objective: To study the B scan ultrasonography before cataract surgery in eyes with dense cataracts. Methods: This was a cross-sectional study. A total of 510 patients and either sex were included. After detailed clinical examination, all patients underwent ocular B scan USG for posterior segment evaluation preoperatively. Results: 625 eyes of 510 patients were studied. Of the 510 patients, 40.2% were 61-70 years of age and 61.8% were males. Of the 625 eyes, 78 eyes (12.5%) had one or more than one positive finding on B scan USG. It was found that the most common findings were R.D and PVD found in 4% and 2% of the eyes respectively followed by posterior staphyloma (1.6%), choroidal detachment (1.6%).and vitreous hemorrhage in 0.8% eyes. Abnormal USG findings were found more frequently among hypertensives (50%) and diabetics (41.7%). Posterior synechiae was in 10.8%. The elevated IOP was observed in 5.9%. Conclusion: B-scan ultrasound has significant importance in the preoperative evaluation of patients with dense cataracts to detect pathologies.This may influence the surgical strategy and the postoperative visual prognosis.

“…Ophthalmoscope and OCT are easily affected by refractive medium turbidity [ 2 ]. Although ocular B-ultrasound is not affected by refractive medium turbidity, its accuracy in diagnosing retinopathy is not high [ 1 , 3 ]. In recent years, objective visual electrophysiology technology has been widely studied by cataract experts [ 4 , 5 ].…”

Purpose. To explore the value of visual electrophysiology in evaluating the fundus function of mature cataract patients. Methods. 124 mature cataract patients (153 eyes) were examined before cataract surgery; the examinations included best corrected visual acuity (BCVA), pattern visual evoked potential (PVEP), full-field electroretinogram (ffERG), and multifocal electroretinogram (mfERG). According to the postoperative fundus conditions, the subjects were divided into two groups: the no fundus disease group and the fundus disease group. Approximately one month after the operation, BCVA was measured, and visual electrophysiology was performed on subjects who had a stable fundus condition and had not received treatment for fundus disease. Results. One month after cataract surgery, BCVA ≤ 0.3 logMAR was found in 60 eyes (96.8%) without fundus disease and 59 eyes (64.8%) with fundus disease. Compared with the group without fundus disease, the preoperative electrophysiological examination of the group with fundus disease showed that the amplitude of ffERG waves and the amplitude density of the P1 wave in the 2nd to 5th rings of mfERG were decreased (all P < 0.05). ffERG and mfERG can be used for differential diagnosis of fundus disease (all P < 0.05), while PVEP has no significant diagnostic value for fundus disease (all P > 0.05). In the group without fundus disease, the amplitude of the PVEP 15′ P100 wave and the amplitude of dark-adapted (DA) 0.01 b-wave, DA 3.0 a-wave, and DA 10.0 a-wave were negatively correlated with postoperative logMAR BCVA (all P < 0.05). In the group with fundus disease, the amplitude of PVEP and ffERG and the amplitude density of mfERG were negatively correlated with postoperative logMAR BCVA (all P < 0.05). In the eyes of cortical cataracts, some parameters of PVEP, ffERG, and mfERG were significantly different before and after surgery. In the eyes of nuclear cataracts, some parameters of ffERG and mfERG were significantly different before and after surgery. In the eyes of posterior subcapsular cataracts, some parameters of PVEP and ffERG were significantly different before and after surgery. Conclusions. ffERG and mfERG can be used to detect fundus disease in mature cataract patients. The preoperative visual electrophysiological examination has high clinical value in predicting postoperative vision of mature cataract patients with fundus disease. Different types of cataracts have different effects on electrophysiological examination results. When interpreting the electrophysiological report, it is necessary to consider the existence of cataracts. This trial is registered with 2019-K068.

Cataract is a treatable cause of blindness. A good post-operative outcome can be achieved with appropriate evaluation of unsuspected posterior segment disorders before the surgery by B san Ultrasonography evaluation. This study assess use B-scan ultrasonogram to visualize status of posterior segment of eye glob, hidden disorders and their percentage that affect the prognosis outcome of cataract surgery. A prospective study was done at the radiological department, using B -scan ultrasound examination of 151 patient candidates for cataract surgery, characterized as 128 patient of non-traumatized and 23 patient with a history of trauma for more than one month. Out of 151 patient, there was 38 patient (25.1%) with abnormal posterior segment disorders. In the non-traumatic group, out of 128 patient, there are 23 patients (17.96%) with abnormal posterior segment disorders. In the traumatic group, out of 23 patient, there are 15 patients (65%) of the abnormal posterior segment. The highest posterior segment disorder in non-traumatic cataract was retinal detachment of 10 patient (43.47%) and at traumatic patient of retinal detachment of 5 patient (33.33%) and vitreous body haemorrhage of 5 patient (33.33%). For patients with systemic risk factors as diabetes mellitus and hypertension, the most frequent lesion was vitreous haemorrhage. In conclusion B-scan ultrasonogram is highly valuable, sensitive and specific, and widely available for detection of posterior segment disorders and its recommended to be a routine examination before the cataract surgery.
