B-Scan Ultrasonography to Screen for Retinal Tears in Acute Symptomatic Age-Related Posterior Vitreous Detachment

Reliability of Ocular Ultrasonography Findings for Pre-surgical Evaluation in Various Vitreo-retinal Disorders

“…Ultrasound is being routinely used in ophthalmology for diagnosis and management of various conditions, such as retinal detachment (RD), vitreous hemorrhage, ocular trauma, intraocular foreign bodies (IOFB), retinal tears with or without posterior vitreous detachment (PVD), dense cataract, and intraocular tumors. [1][2][3][4][5][6][7][8][9][10][11][12][13] These studies found that USG provides valuable and reliable preoperative information for the management of these patients.…”

Ophthalmic Ultrasonography

“…A second commonly seen entity in the emergency setting is loss of sight secondary to retinal detachment, a break or a tear in the retinal epithelium ( Figure 8). [14][15][16][17][18] The most common symptoms are seeing floaters or flashing lights within the eye. 19 If the patient experiences a shadow or curtain that affects any part of the vision, this can indicate that a retinal tear has progressed to a detached retina, a true medical emergency that must be treated quickly to avoid permanent loss of vision.…”

“…The sonographic appearance of retinal detachment is typically nonlayering, low-level echoes within the vitreous body that are unattached to the periphery of the globe. 15,16 Retinal detachment is seen usually in two different instances. The first is an older individual whose vitreous detaches due to age, causing tiny, horseshoe-shaped holes Journal of Diagnostic Medical Sonography that allow fluid to pass into and accumulate in the subretinal space.…”

“…The first is an older individual whose vitreous detaches due to age, causing tiny, horseshoe-shaped holes Journal of Diagnostic Medical Sonography that allow fluid to pass into and accumulate in the subretinal space. 15 It can also be found in patients who have experienced trauma. 16 Regardless of the cause, retinal detachment must be diagnosed and treated rapidly to prevent monocular vision loss.…”

Spectral-Domain Optical Coherence Tomography Imaging of Postoperative Scleral Buckles

“…1,3,4 While retinal breaks are treated with laser or cryopexy to seal the retina into place, the primary causes of scleral buckle failure are unsupported retinal breaks and inadequate or misplaced buckles. 5 Frequently, ultrasound is used to supplement clinical evaluation of vitreoretinal disease, 6,7 and a recent report illustrates visualization of a successful scleral buckle and the overlying vitreoretinal disease with ultrasound. 8 Ultrasound is useful in cases of difficult ocular media that limit clinical examination but offers lower resolution than optical coherence tomography (OCT) when evaluating retinal, subretinal, and vitreous diseases.…”
