“…In a study done by Streho et.al., it was further found that B-scan USG is able to detect superior retinal tears predominantly than in other quadrants (71% cases among the 101 eyes of 100 patients studied). 13 Case studies published have also shown that ultrasound B scan is an indispensable tool for the diagnosis of Ocular Cysticercosis, locating masses/ growths/ tumours even in complete cataract cases, diagnosis of microvascular changes associated with optic disc drusen, etc. [14][15][16] In a study among 102 Sudanese adult patients with cataract done by Gareeballah et.al., sonographic findings showed posterior vitreous detachment (PVD) in 19.2%, vitreous hemorrhage of 0.98%, and complicated PVD in 1.96%.…”

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.

“…RD, PHPV, intraocular tumors and other common fundus diseases can be diagnosed by routine ocular examination and conventional ultrasound or/and UBM when the refractive medium is clear, the lesion size is relatively limited and the lesion is not complex, and in most cases we can conclude accurate diagnosis after the combination of optical coherence tomography (OCT), fundus fluorescein angiography (FFA), indocyanine angiography (ICG), etc [12][13] . When the refractive medium is unclear or the refractive pathway is blocked, such as severe cataract, pupil membrane closure, severe vitreous opacity and so on, the above examinations cannot be carried out and ultrasound is necessary to assist in diagnosis [2] . During ultrasound examination, various practical difficulties can be encountered: 1) The ultrasonic features of the lesions are complex and difficult to diagnose.…”

“…B -scan ultrasound, mainly used to help diagnose vitreous and retinal diseases, is a routine diagnostic method in ophthalmology because of it is convenient, low cost, noninvasive and not affected by opacity of refractive media [1][2][3] . Ultrasonic biomicroscope (UBM), because of its high frequency, can clearly image the anterior segment (from cornea to posterior capsule of lens) under normal condition, mainly used to observe the pathological changes of cornea, anterior chamber, ciliary body and lens [4][5][6][7][8][9] .…”

AIM: To evaluate the diagnostic value of panoramic immersion B-scan ultrasonography (Pano-immersion B-scan, PIB) in complex retinal detachment (RD), persistent hyperplastic primary vitreous (PHPV) and intraocular tumors. METHODS: The clinical data of 44 patients collected from May 2012 to December 2019 in Chinese PLA General Hospital was retrospectively studied. All of these patients underwent PIB of the eye, because it was difficult to diagnose by routine ocular fundus examination, conventional ultrasound or/and ultrasonic biomicroscope (UBM) due to opacity of refractive media, pupillary occlusion, large involvement or special location of the lesion. The imaging features of difficult cases in PIB were analyzed. The diagnosis accuracy rating of PIB were evaluated and contrasted with conventional ultrasound or UBM by the standard of intraoperative diagnosis or/and pathological results. RESULTS: According to intraoperative diagnosis or pathological results as gold standard, among the 44 cases, there were 19 cases missed diagnosis, misdiagnosed or difficult-to-diagnose by conventional ultrasound or UBM, including 4 cases of long-standing RD difficult to diagnose, 4 cases misdiagnosed, and 11 cases incompletely observed or miss diagnosed. The diagnostic accuracy rate of PIB and conventional ultrasound or UBM were 100% (44/44) and 56.82% (25/44), and the sensitivity of them were 100% and 56.82%. All the patients underwent PIB and were diagnosed as RD (15 cases), retinal and choroidal detachment (4 cases), subchoroidal hematocele (1 case), vitreous opacity and/or organic membrane formation (4 cases), PHPV (12 cases), iris and/or ciliary body tumors (3 cases), and choroidal tumors (6 cases). According to the intraoperative diagnosis or pathological results, the diagnostic coincidence rate of PIB was 100%, which was significantly higher than conventional ultrasound and UBM. CONCLUSION: PIB can help to accurately diagnose complex RD, PHPV, and intraocular masses with special location or/and excessive size. It has important diagnostic value for patients with equivocal findings at conventional ultrasound examination.

Introduction: Long axial length (AL) is a risk factor for myopia. Although family studies indicate that AL has an important genetic component with heritability estimates up to 0.94, there have been few reports of AL-associated loci.Methods: Here, we conducted a multiethnic genome-wide association study (GWAS) of AL in 19,420 adults of European, Latino, Asian, and African ancestry from the Genetic Epidemiology Research on Adult Health and Aging (GERA) cohort, with replication in a subset of the Consortium for Refractive Error and Myopia (CREAM) cohorts of European or Asian ancestry. We further examined the effect of the identified loci on the mean spherical equivalent (MSE) within the GERA cohort. We also performed genome-wide genetic correlation analyses to quantify the genetic overlap between AL and MSE or myopia risk in the GERA European ancestry sample.Results: Our multiethnic GWA analysis of AL identified a total of 16 genomic loci, of which 5 are novel. We found that all AL-associated loci were significantly associated with MSE after Bonferroni correction. We also found that AL was genetically correlated with MSE (rg = −0.83; SE, 0.04; p = 1.95 × 10−89) and myopia (rg = 0.80; SE, 0.05; p = 2.84 × 10−55). Finally, we estimated the array heritability for AL in the GERA European ancestry sample using LD score regression, and found an overall heritability estimate of 0.37 (s.e. = 0.04).Discussion: In this large and multiethnic study, we identified novel loci, associated with AL at a genome-wide significance level, increasing substantially our understanding of the etiology of AL variation. Our results also demonstrate an association between AL-associated loci and MSE and a shared genetic basis between AL and myopia risk.
