Shear wave elastography (SWE) is a non-invasive diagnostic imaging technique that maps the elastic properties of tissues. This modality is being increasingly developed in other areas of medicine, offering a new type of high-quality ultrasound examination, since it increases specificity and thus improves diagnostic accuracy. This method is similar to manual palpation, showing the elastic properties of biological tissues and providing a kind of reconstruction of the internal structure of soft tissues based on measurement of the response to tissue compression. In ophthalmology, it already appears promising for diagnosis and in evaluating changes in extraocular muscles and orbital tissues in patients with endocrine orbitopathy. Shear wave elastography offers three main innovations: the quantitative aspect, dimensional resolution, and real-time imaging ability. Determination of the utilization rate of this method and its inclusion in the diagnosis of endocrine orbitopathy is still a question and the object of clinical studies currently under way.
PURPOSE: To evaluate long-term refractive outcomes of implantable collamer lens (ICL) implantation and late postoperative complications. METHODS: We assessed outcomes of patients who underwent ICL implantation (type ICM V4 for myopia, ICH V3 for hyperopia, TICM V4 for astigmatism) in our department between 1998 and 2013. It comprised 62 eyes (40 myopic and 22 hyperopic). The average follow-up period was 10.5 years. We evaluated: uncorrected and best-corrected visual acuity (UCVA and BCVA), spherical equivalent (SE), ICL vault, endothelial cell density and late postoperative complications. RESULTS: In myopes, the average UCVA was 1.0±0.37 and BCVA 1.18±0.38, in hyperopes 0.78±0.19 and 1.14±0.18, respectively. The average SE in myopes, whose target refraction was emmetropia, was -0.6±0.83 Dsf, in hyperopes +0.73±0.93. Central ICL vault was 206.16μm±105.94, (range 10-427) in myopes, 195.5μm±109.09, (range 20-404) in hyperopes. The most common late postoperative complication was cataract formation. Three myopic eyes (7.5%) developed symptomatic anterior subcapsular opacities with loss of at least two lines of BCVA. Cataract significantly affecting visual acuity occurred in 5 myopic eyes (12.5%) and 2 hyperopic eyes (9.09%). In these eyes, ICL removal and cataract surgery was performed. CONCLUSIONS: In our experience, ICL implantation in moderate and high ametropia was effective and relatively safe. The most common late complication was cataract formation. This complication can be managed effectively surgically with good refractive outcomes without loss of BCVA.

A 73-year-old male with a history of bladder carcinoma presented with conjunctival melanoma that was excised. Multiple lung metastases were detected during diagnostic work-up. Because of uncertainty about the histology of the metastatic lung tumor, a biopsy was performed that revealed a third primary non-small cell carcinoma of the lung. This case illustrates the need to obtain histological verification in patients with conjunctival melanoma and distant metastases, especially if metastases are detected early in the follow-up.
