“…Multiple tears were systematically sought. Another recent study confirmed a sensitivity of 100% for the detection of rhegmatogenous retinal detachment and for the detection of new retinal tears in patients without retinal detachment [7] using a standardized scanning protocol and a dedicated ophthalmic ultrasonographer, as it was the case in our study.…”

Introduction. When fundus examination is not possible, ultrasonography (US) is an accurate tool for the diagnosis of retinal tears (RT). The aim of this study was to describe the predominant location of RT, the factors influencing their location, and the vitreous status of eyes with RT using US. Methods. A prospective study was conducted in all patients diagnosed with RT by B-scan US (Aviso, Quantel Médical, Clermont-Ferrand, France). The primary endpoint was to assess RT preferential location using US. Secondary endpoints were the rate of posterior vitreous detachment (PVD), number of eyes with multiple RT, and axial length (AL). Results. A total of 101 eyes of 100 patients with RT were included. RT main location was in the superior quadrants (either nasal superior, strictly superior, or temporal superior) in 71% of cases. All patients were diagnosed with PVD by US, and 79% had a vitreous hemorrhage. Twelve eyes (13%) were diagnosed with multiple RT. The mean AL was 24.62 ± 2 mm, and it was significantly longer in eyes without superior RT (25.52 mm versus 24.37 mm; p=0.004). Conclusion. In this study, we showed a superior location of RT diagnosed by US in more than two-thirds of cases associated with a significantly shorter AL than in other locations. This finding could increase US sensitivity for RT detection and help to improve the US learning curve of ophthalmologists in training and surgical decision-making when the retina is inaccessible due to opacity media.

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.

“…In patients older than 80, the VH is more likely to be secondary to wet age-related macular degeneration (AMD) or a macroaneurysm rather than a posterior vitreous detachment (PVD). In addition to this, Sandinha et al [ 11 ] described that using a dedicated ophthalmic ultrasonographer and standardised scan protocol could significantly improve the sensitivity of identifying tears and detachments and increase the proportion of such patients who could be managed conservatively.…”

A Case Report of Conservative Management for a Roller-Coaster-Related Vitreous Haemorrhage

et al. 2018

The purpose of this report is to describe the case and management of an unexplained vitreous haemorrhage that occurred after repeated roller-coaster riding. The authors inadvertently demonstrate the value of observation over immediate surgery in certain situations and review the literature on vitreoretinal and other ocular complications after roller-coaster riding. A 26-year-old male presented 12 h after riding high-velocity roller-coasters with a left vitreous haemorrhage. A hazy view of the retina and B-scan revealed a bullous area of superior-temporal retinal lifting. A diagnosis of a presumed macula-on retinal detachment was made and the patient was listed for a pars plana vitrectomy retinal detachment repair. An abnormal clotting result, which was subsequently found out to be erroneous, ultimately delayed the procedure. During this delay the vision and retinal view improved to an extent whereby the diagnosis of a retinoschisis with an intraretinal cyst was made and surgery was avoided. The patient regained 6/6 vision, without the need to undergo surgery. Historically the management of an unexplained vitreous haemorrhage was observation with serial B-scans. The current evidence and practice for treating unexplained vitreous haemorrhage have since moved towards early surgical intervention. The authors highlight that despite the current trend, a place remains for conservative management for selected cases.
