Follow up by colour Doppler imaging of 102 patients with retinal vein occlusion over 1 year

The diagnosis of Graves’ ophtalmopathy (GO) is based on clinical examination, laboratory tests (indicating thyroid dysfunction and inflammatory and autoimmune unbalance) and imaging studies (such computed tomography, magnetic resonance imaging, ultrasound and colour Doppler imaging). Imaging studies can be helpful in establishing the certain diagnosis of GO, because they provide objective morphological findings of the orbital structures. An important role of imaging studies is revealed in differential diagnosis versus other orbital diseases and can be also used to evaluate the progression of the disease and follow-up after clinical or surgical treatment.

We present the case of a rock climber with a rupture of the A3 flexor sheath pulley. The diagnosis was confirmed with Colour Doppler Imaging (CDI) and with B-mode ultrasound imaging, and the surgical repair was evaluated in the same way. Vertical displacement of the flexor tendon meant that using CDI measurements of the longitudinal movements was not possible. However, using computer analysis of digitized B-mode images from texture patterns identified in the tendons, the vertical and longitudinal components of movement during flexion were calculated. The repair of the pulley was shown to produce tendon movement ratios nearer those of the control digit of the opposite hand.

AbstractTo evaluate the effects of intravitreal ranibizumab injection (IVR) on metamorphopsia in patients with branch retinal vein occlusion (BRVO), and to assess the relationship between metamorphopsia and inner retinal microstructure and other factors. Thirty-three treatment-naïve eyes of 33 patients with macular edema caused by BRVO with at least 12 months of follow-up were included. The degree of metamorphopsia was quantified using the M-CHARTS. Retinal microstructure was assessed with spectral-domain optical coherence tomography. Disorganization of the retinal inner layers (DRIL) at the first month after resolution of the macular edema (early DRIL) and at 12 months after treatment (after DRIL) was studied. Central retinal thickness (CRT), and status of the external limiting membrane as well as ellipsoid zone were also evaluated. IVR treatment significantly improved best-corrected visual acuity (BCVA) and CRT, but the mean metamorphopsia score did not improve even after 12 months. Post-treatment metamorphopsia scores showed a significant correlation with pre-treatment metamorphopsia scores (P < 0.005), the extent of early DRIL (P < 0.05) and after DRIL (P < 0.05), and the number of injections (P < 0.05). Multivariate analysis revealed that the post-treatment mean metamorphopsia score was significantly correlated with the pre-treatment mean metamorphopsia score (P < 0.05). IVR treatment significantly improved BCVA and CRT, but not metamorphopsia. Post-treatment metamorphopsia scores were significantly associated with pre-treatment metamorphopsia scores, the extent of DRIL, and the number of injections. Prognostic factor of metamorphopsia was the degree of pre-treatment metamorphopsia.
