Background And Objective: Retinal imaging can help differentiate retinoschisis (RS) from retinal detachment (RD). This study describes new sonographic features of RS using ultrasound biomicroscopy (UBM) and evaluates their diagnostic value.
Patients And Methods: Medical records of subjects diagnosed with RS and RD who underwent imaging prior to intervention were reviewed. Images were evaluated for detachment shape ultrasound (US) B-mode, as well as presence of intraretinal pillars, retinal layers split, and intraretinal cysts on UBM.
Results: Of 48 eyes from 48 patients in the study, 25 were diagnosed as RS and 23 as RD. "Retinal layers split" was the most common UBM finding in the RS group (72%), followed by intraretinal pillars (64%) and intraretinal cysts (36%). No RD case exhibited these findings (P < .001).
Conclusions: UBM might assist in difficult cases to differentiate between RS and RD by detection of the unique sonographic features of RS described herein. [Ophthalmic Surg Lasers Imaging Retina. 2019;50:e196-e202.].

Department of Biomedical Engineering, University of Houston, Houston, TX, USA.
Purpose: To assess the safety of acoustic radiation force optical coherence elastography in the crystalline lens in situ.
Methods: Acoustic radiation force (ARF) produced by an immersion single-element ultrasound transducer (nominal frequency = 3.5 MHz) was characterized using a needle hydrophone and used for optical coherence elastography (OCE) of the crystalline lens.
Purpose: To evaluate dynamic changes in ciliary parameters and Implantable Collamer Lens V4C (ICL) (STAAR Surgical) haptic position using mydriatic and miotic agents and their effects on the central and peripheral vault.
Methods: This study involved 80 eyes from 40 consecutive patients (mean age: 28.05 years; range: 19 to 42 years) examined 3 months after ICL implantation.
High-intensity focused ultrasound: an innovative approach for micro-manipulation of demineralized dentine.

Background: Treatment of deep carious lesions poses significant challenges in dentistry, as complete lesion removal risks compromising pulp vitality, while selective removal often reduces the longevity of restorations. Herein, we propose a minimally invasive approach using High-Intensity Focused Ultrasound (HIFU) for microscale removal of carious dentine. Concurrently, HIFU's antimicrobial effects against associated cariogenic biofilms and the corresponding thermal and biological impacts on surrounding tissues were investigated.

Photoacoustic imaging has emerged as a promising modality for medical imaging since its introduction. Photoacoustic microscopy (PAM), which is based on the photoacoustic effect, combines the advantages of both optical and acoustic imaging modalities. PAM facilitates high-sensitivity, high-resolution, non-contact, and non-invasive imaging by employing optical absorption as its primary contrast mechanism.

However, ULM performance relies heavily on microbubble (MB) signal sparsity, the number of detected MBs, and signal-to-noise ratio (SNR), all of which vary in clinical scenarios involving bolus MB injections. These sources of variations underscore the need to optimize MB dosage, data acquisition timing, and imaging settings in order to standardize and optimize ULM of microvasculature.
