Significance of Ultrasonography in Evaluation of Vitreo-retinal Pathologies

Abstract

Ultrasonography is useful part of ophthalmic examination for detection, evaluation and follow up of different vitreo-retinal pathologies.

Imaging in diabetic retinopathy

“…However, ultrasonography examination can change the initial treatment plan in 4.8% and subclassify diagnosis and aid with further surgical planning in 13% of patients scheduled for pars plana vitrectomy. 2 When considering only patients with poor visualization of the posterior segment, these figures are even higher at 9% and 20%, respectively. 2 These outcomes are consistent with previous studies that reported ultrasonography established or changed the management plan in 8% and subclassified the diagnosis in 13% of patients with various posterior segment pathologies including cataract and choroidal detachment.…”

“… 1 Furthermore, in studies analyzing various vitreoretinal disorders, the overall sensitivity of ultrasonography in identifying the anatomical position of the retina was 97.3–97.7%. 2 3 However, in patients with more complex ultrasonography findings, such as tractional retinal detachment and choroidal detachment, the agreement between the ultrasonography and the surgical findings is slightly lower, between 92.2% 3 and 92%, 4 respectively. The main cause of misdiagnosis could be defined as the presence of multiple complicated echoes in eyes with tractional retinal detachment.…”

Re: Evaluation of posterior vitreous detachment after uneventful phacoemulsification surgery by optical coherence tomography and ultrasonography

“…Such PVD could have been missed in previous studies, due to the inability to detect the early PVD by either clinical examination or ultrasonography. Combined slitlamp biomicroscopy, OCT and ultrasonography provide reliable information regarding the state of the vitreoretinal interface and PVD presence in all stages, regardless of underlying vitreoretinal pathology …”
