Introduction: Dry eye disease (DED) is a multifactorial disease of tears and ocular surface that results in symptoms of discomfort, visual disturbance, and tear film instability leading to decrease of vision, productivity and quality of life, and blindness. DED diagnosis remains difficult and underdiagnosed regarding inconsistency between subjective symptoms and clinical findings. Tear break-up time (TBUT) is an objective indicator of tear film stability in diagnostic DED. A novel smartphone attachment, namely SEC (smart eye camera), could mimic conventional slit lamp to assess TBUT and beneficial in facilitating DED diagnosis. Reliability between a non and an ophthalmologist in TBUT assessment and DED diagnosis is observed in this study.
Purpose: To determine interobserver reliability of TBUT measurement for diagnosing DED using SEC.
Design: This a cross-sectional analytic study involving 99 participants (198 eyes) aged 40 years who visited Pratama Gema Santi Hospital, Nusa Penida, from September 2nd to 4th, 2022, with consecutive sampling technique.
Methods: Fluoresceined eyes were filmed using the SEC device and apps, continued by masked ophthalmologist and resident assessing TBUT based on the video. The primary outcome is interobserver reliability for TBUT measurement and DED diagnosis.
Results: The mean age of participants was 55.22±9.78 years, 48.5% male and 51.5% female. The reliability of interobserver in assessing DED based on TBUT test is 0.78 (95% CI=0.31-1.26, -value=0.001), and interobserver reliability in diagnosing DED based on OSDI and TBUT showed good agreement (weighted kappa=0.71). Good interobserver reliability underscores that non-ophthalmologists can diagnose DED based on TBUT video using SEC.
Conclusion: SEC video has good interobserver reliability to assess TBUT for DED diagnosis. SEC can be used as one of the methods in assessing DED in limited health care facilities. The high reliability of interobserver assessment indicates that DED diagnosis using video taken with SEC may be useful for telemedicine evaluation in remote areas.

Evaluation of Local Tumor Outcomes Following Microwave Ablation of Colorectal Liver Metastases Using CT Imaging: A Comparison of Visual versus Quantitative Methods.
Radiol Imaging Cancer

From the Department of Radiology, Royal Marsden Hospital NHS Foundation Trust, 203 Fulham Road, London SW3 6JJ, England (J.D.S., L.K., L.P., J.M., N.K., D.M.K., E.J.); Institute of Cancer Research, London, England (N.P., D.M.K.); and Department of Radiology and Nuclear Medicine, Rijnstate Hospital, Arnhem, the Netherlands (W.O.).
Purpose To compare visual versus quantitative ablation confirmation for identifying local tumor progression and residual tumor following microwave ablation (MWA) of colorectal liver metastases (CRLM). Materials and Methods This retrospective study included patients undergoing MWA of CRLM from October 2014 to February 2018. Two independent readers visually assessed pre- and postprocedure images and semiquantitatively scored for incomplete ablation, using a six-point Likert scale, and extracted quantitative imaging metrics of minimal ablative margin (MAM) and percentage of tumor outside of the ablation zone, using both rigid and deformable registration.

Bone and Joint Reconstruction Research Center, Department of Orthopedics, School of Medicine, Iran University of Medical Sciences, Tehran, Iran.
Objectives: Previous studies of the association between tibial slope and meniscal tear have led to contradictory results. In this regard, the present study aimed to examine the effect of medial tibial plateau slope on the incidence of isolated medial meniscal tear.
Methods: This study was performed on 75 patients with a posterior horn medial meniscal tear and 150 matched control subjects.
Evaluation of Tele-Education in Malawi for Detection of Macular Features Using Optical Coherence Tomography.

Department of Ophthalmology, University Hospital Tübingen, Germany.
Purpose: The study aimed to assess the reliability of tele-education in training a Malawian ophthalmology resident to interpret optical coherence tomography (OCT) images of patients with macular conditions.
Methods: This was a retrospective analysis of 1000 macula-centered OCT image series from 1000 eyes of 1000 consecutive patients from Malawi, which involved initial interpretation by a German retina specialist (observer 1) (T). Observer 1 then trained a Malawian resident (observer 2) via email, and observer 2 independently interpreted images at T, followed by face-to-face training in Malawi and reinterpretation at T and T (3-month intervals).
Association Between Rotator Cuff Tears and Shoulder MRI Parameters: Importance of Arthroscopic Validation in Coronal Acromiohumeral Interval Measurement.

Background: Magnetic resonance imaging (MRI) measurement parameters-the standard noninvasive diagnostic method for rotator cuff tears (RCTs)-have been used to compare groups with and without RCTs. Arthroscopy is used in definitive diagnosis and treatment.
Purposes: To evaluate the association between RCT and shoulder angles and distances on MRI in patients with and without arthroscopically validated RCT and to determine whether the degree of rotator cuff fatty degeneration affects the MRI measurements.
The Superior Glenoid Humeral Ligament's Role in Superior Labrum Anterior-Posterior Lesions and Subtype Classification Based on Arthroscopic Views: A Multicenter, Retrospective Study.

Background: Superior labrum anterior-posterior (SLAP) lesions are common shoulder injuries. The 10-type classification system has been widely used to diagnose SLAP lesions since it was proposed. However, growing evidence from arthroscopic studies indicates the existence of many SLAP lesions, especially those associated with superior glenoid humeral ligament (SGHL) injuries, that were not included in the initial classification.
