PURPOSE: Ocular surface disease (OSD) is highly prevalent in eyes treated with chronic, topical antiglaucoma (A/G) therapy. The purpose of this study was to utilize in vivo confocal microscopy (IVCM) to evaluate the corneal morphology, including characteristics of corneal epithelial cells, presence of epithelial dendritic cells (DCs), and characteristics of subbasal nerve plexus, of eyes under topical A/G therapy versus normal eyes. METHODS: Central corneal images were prospectively captured from 30 eyes of 16 patients under topical A/G therapy (>6 months) and 20 normal control eyes, using IVCM (HRT 3 RCM, Heidelberg, Germany)...

RATIONALE: Recently, some ophthalmologists performed PRK or LASEK surgeries in FFKC suspicious patients, which is supposed to prevent FFKC evolvement via fibrotic scar formation. Our report indicates that keratectasia can occur after LASEK in FFKC suspicious patients, highlighting the importance of stricter regulation of patient recruitment before the procedure and postoperative follow-up. PATIENT CONCERNS: This is a report of a 25-year-old man with poor corrected distance visual acuity (CDVA) 6 years after LASEK...

This study investigated the feasibility of opportunistic osteoporosis screening in routine contrast-enhanced MDCT exams using texture analysis. The results showed an acceptable reproducibility of texture features, and these features could discriminate healthy/osteoporotic fracture cohort with an accuracy of 83%. INTRODUCTION: This aim of this study is to investigate the feasibility of opportunistic osteoporosis screening in routine contrast-enhanced MDCT exams using texture analysis. METHODS: We performed texture analysis at the spine in routine MDCT exams and investigated the effect of intravenous contrast medium (IVCM) (n = 7), slice thickness (n = 7), the long-term reproducibility (n = 9), and the ability to differentiate healthy/osteoporotic fracture cohort (n = 9 age and gender matched pairs)...

Purpose: To determine if corneal subbasal nerve plexus (SBP) parameters derived from wide-area depth-corrected mosaic images are associated with type 2 diabetes. Methods: One hundred sixty-three mosaics were produced from eyes of 82 subjects by laser-scanning in vivo confocal microscopy (IVCM). Subjects were of the same age, without (43 subjects) or with type 2 diabetes (39 subjects). Mosaic corneal nerve fiber length density (mCNFL) and apical whorl corneal nerve fiber length density (wCNFL) were quantified and related to the presence and duration of diabetes (short duration < 10 years and long duration ≥ 10 years)...
