“…Vitreous pathology: Asteroid hyalosis, which is characterized by fine echogenic opacities within the vitreous cavity, is seen on B-mode ultrasound because of fatty calcium soap deposits and which produce a sparkling appearance [ 7 , 13 ]. Vitreous hemorrhage is one of the most common pathologies of posterior segment ocular lesion, which may occur due to vasoproliferative disease (diabetic retinopathy), posterior vitreous detachment, age-related macular degeneration and trauma.…”

“…B-mode USG shows initial echogenic contents within the vitreous cavity and with the subsequent organization of hemorrhage leading to neomembrane formation. Long-standing vitreous cavity membrane adherent to the retina might cause tractional retinal detachment and in such a situation vitrectomy is required [ 3 , 13 , 14 ]. In posterior vitreous detachment (PVD), the posterior vitreous capsule detaches from the retina and appears as an undulating membrane that moves freely during dynamic B-mode ocular USG and should swirl away from the optic disc region [ 3 , 13 ].…”

Background: High-resolution Ultrasound (USG) provides good anatomical details of the ocular posterior segment and depicts the various pathological conditions affecting the ocular posterior segment, which helps ophthalmologists for choosing the best treatment options. This study aims to evaluate the utility of High-resolution Ultrasonography in the Evaluation of Posterior Segment Ocular lesions by using Sensitivity and Specificity.Materials and Methods: A hospital-based retrospective study enrolled 81 patients in a tertiary care hospital. Clinical and ophthalmological examinations were performed followed by USG of the orbits. B-mode USG was done with a 7.5–13 MHz linear probe. The final diagnosis was made by correlating the USG findings with clinical and ophthalmological examinations.Statistical analysis: Sensitivity, specificity, the positive predictive value, the negative predictive value, and the accuracy of B-scan USG were compared with the ophthalmological findings by using the Chi-square test.Results: Of 81 patients (n=48 males and n=33 females) with a mean age of 38.98 ± 16.48 [SD] years, posterior segment ocular lesions in association with cataracts were found in 27 (33.3%) patients, whereas 14 (51.9%) patients had posterior vitreous detachment (PVD), 10 (37%) patients had retinal detachment (RD), and 1 (3.7%) patient had choroidal detachment (CD). Posterior segment ocular pathologies were found in 17 (21%) patients with blunt ocular injuries, whereas 8 (47.1%) patients had PVD, 4 (23.5%) patients had RD and 4 (23.5%) patients had CD. The ocular USG had a sensitivity of 87.32%, specificity of 80%, and accuracy of 86.42% with a statistically significant difference between the USG findings and the Ophthalmology diagnosis of the posterior segment ocular abnormalities of a p-value of 0.0005.Conclusion: High-resolution ultrasound is one of the best and an easily available imaging modality for the evaluation of posterior segment ocular pathologies, especially in the presence of opaque ocular media.

“…A potential mimicker of VH in particular is asteroid hyalosis, a relatively rare, benign degenerative condition that often has little impact on vision [3,4]. Similar to VH, POCUS findings of asteroid hyalosis consist of mobile hyperechoic opacities within the vitreous [5][6][7]. Being able to recognize the subtle differences between the two is important, as the management of each is quite different.…”

Asteroid Hyalosis: A Mimicker of Vitreous Hemorrhage on Point of Care Ultrasound: A Case Report

Ocular point of care ultrasound (POCUS) can help make timely recognition of multiple emergent ocular conditions and differentiate these from more benign conditions. While asteroid hyalosis (AH) is benign, it can easily mimic the more potentially serious vitreous hemorrhage on ocular POCUS, as both consist of numerous echogenic opacities within the vitreous with a classic “washing machine” appearance with eye movement. However, asteroid hyalosis particles tend to be more discrete, hyperechoic, scintillating, and seen throughout the vitreous. Knowledge of this mimic and ability to recognize the subtle sonographic differences can help differentiate these disease processes, which can influence management and potentially disposition.
