“…Our experience has also shown that ultrasound instrumentation needs special care and a budget for repair and replacement from time to time. Reviewing the literature of B-scan ultrasound applications in eyes with dense cataracts in low-income settings, the publications were mainly from India and Pakistan [10][11][12][13] and only a few from Sub-Saharan Africa [6,14]. In studies directly comparable with ours where the selected patients were screened, the rate of retinal detachment varied from 0.9% [13] to 4.5% [10], which was in line with our findings of 2.97%.…”

“…The average frequency of retinal detachment in selected patients has been studied in detail by many authors [6,7,10,12,13,15]. Their studies have a total of 2854 patients with an average rate of retinal detachment of 3%.…”

“…However, in LMIC countries, many patients do not have access to such procedures for socioeconomic reasons. Moreover, such sophisticated tests may not be available in many centers [6,7]. In addition, orbital pathology is poorly managed in many LMIC countries, and even in referral centers, sub-specialization in the orbit is rare.…”

The aim of this study was to analyze the use of the diagnostic B-scan ultrasound. Should it be made accessible to all surgical centers in Sub-Saharan Africa in order to (i) avoid unnecessary cataract surgery and (ii) evaluate extraocular pathology? This study was conducted in Kinshasa from 2006 to 2019. Three hundred and twenty-three patients were included and separated into two groups. Group 1 included 262 patients with dense cataract. Group 2 consisted of 61 patients with pathologies of the ocular adnexa, and all were examined with a B-scan ultrasound. In group 1, there were 437 systematically screened eyes. Three hundred and ninety-eight eyes (91.08%) showed no abnormalities, 13 (2.97%) retinal detachments were identified, and 15 (3.43%) demonstrated a detached posterior hyaloid membrane. In the second group, 61 patients were examined (group 2). In 20 of them, surgery was performed for biopsy, tumor excision, mucoceles drainage, and palliative treatment. The need for routine B-scan examinations in dense cataract patients seems to be limited and can most likely be replaced by a thorough application of locally available examination techniques. B-scan application is recommended to manage orbital patients in the most cost-effective way.

Introduction: Ophthalmic ultrasound (USG) produces real time high resolution images of the eye and orbit. It can categorize and predict the location of pathology in the posterior chamber of eye very well. It is useful even in pre-operative evaluation and diagnosing posterior segment eye disorders. However, the diagnostic accuracy has usually not being studied thoroughly, with special emphasis to its probability of predicting posterior-segment eye disorders using B-scan USG. Objectives: To find out the prevalence and pattern of posterior segment disorders using B-scan ultrasonography, and to find its diagnostic accuracy. Materials and Methods: The study was prospective in nature and conducted in the department of radiodiagnosis and ophthalmology of a tertiary care center of Eastern India. Patients referred to the radiology department for ruling out intra-ocular pathology using B-scan ophthalmic ultrasound were included in the study, irrespective of any age and gender. Data were captured on an excel sheet and analyzed using Stata 12.1 SE. Results: The mean age of 84 study participants was 37.4 ± 19.5 years, with maximum in between 40-50 years. Males were more (72.6%). 50% presented with low vision, and most commonly associated with cataract (45%). Prevalance of posterior segment eye disorders was 13.1%. Sensitivity and negative predictive values were 100%. Post-test probability was 95.5%. Accuracy was however very less (39.3%). Conclusion: Using B-scan ultrasonography for pre-operative assessment and confirmation of diagnosis increases the probability of detecting presence or absence of posterior segment pathology. Absence of posterior segment disorder using this is also very helpful in ruling out disease entirely. It also a very high sensitivity and hence can be used even in rural health centers.
