Ultrasound assesment of retina in patiens with nonexudative and exudative ARMD

Aim. To compare B scan ultrasound signals backscattered from healthy tissues with signals from nonexudative (dry) and exudative (wet) ARMD areas. Materials and methods. We compared 60 cases of healthy tissue area (I group) with 30 cases of early ARMD (II group) and 30 cases of late ARMD (III group) using B scan ultrasound. Results. We observed that amplitude and mean spectral intercept were statistically higher in wet and dry ARMD groups than in healthy areas. Mean spectral intercept was statistically different in comparison ofI and II groups, also in II and III groups. Conclusions: When there are no possibilities to use more specific examination spectral analysis can be used as an additional diagnostic tool.
