Abstract

Background: Ophthalmic B-scan ultrasonography is beneficial investigation in diabetic retinopathy with vitreous hemorrhage & other media opacities, where retina cannot be visualized directly on ophthalmic test. B-scan ultrasonography can demonstrate if retinal detachment is present & can find other posterior segment pathology like vitreous hemorrhage & posterior vitreous detachment.

Objective: To investigate the role of ophthalmic brightness scan (B-scan) ultrasonography in diabetic retinopathy with opaque media.

Patients & techniques: total of one hundred eyes of 100 studied cases with diabetic retinopathy at different grades with any media opacity precluding adequate indirect ophthalmoscopy were recruited between October 2020 and January 2022 at ophthalmology outpatient clinic in Al-Azhar University Hospitals in Cairo and Kobry El-Kobba Military Eye Hospital in Cairo.

Results: This study showed higher prevalence of diabetic retinopathy complications in uncontrolled diabetic patients regarding HbA1c level ≥ 8%, as moderate to severe vitreous hemorrhage was (98%) in uncontrolled diabetic studied cases compared to (36%) in controlled diabetic studied cases, tractional retinal detachment was (26%) in uncontrolled compared only to (2%) in controlled diabetic patients, rhegmatogenous retinal detachment was (6%) in uncontrolled compared to (0.0%) in controlled diabetic patients & combined tractional, rhegmatogenous retinal detachment was (4%) in uncontrolled compared to (0.0%) in controlled diabetic patients.

Conclusion: Ophthalmic B-scan ultrasonography is quick, safe, noninvasive imaging method that can be used with minimum discomfort in ophthalmological practice for detection & assessment of diabetic retinopathy problems in presence of any media opacity.
