Intra- and interobserver reliability of ocular surface analyzer LacryDiag.

Aim: To invastigate intra- and interobserver reliability of interferometry, tear meniscus height (TMH) measurement and meibography (MBG) of an ocular surface analyzer, LacryDiag (Quantel Medical, France).

Methods: Five consecutive measurements and subsequent analysis of interferometry, TMH, and MBG were recorded by two examiners using the LacryDiag. To assess intra- and interobserver reliability, we used Cohen's kappa for categorical variables (interferometry), or intraclass correlation coefficient for continuous variables (TMH, MBG).

Rare case of nasal cavity chondrosarcoma presenting only with unilateral decreased vision.

Chondrosarcomas comprise a heterogeneous group of malignant lesions characterized by production of cartilage matrix. Sinonasal involvement is extremely rare, with nasal congestion and obstruction being the leading symptoms. We present a rare case of large chondrosarcoma of the nasal cavity and paranasal sinuses, primarily presenting with ocular symptoms.

A Retrospective Data Review Confirms That Topical Preservative-Free Hydrocortisone Improves Inflammation in Dry Eye Disease.

Background: Inflammation is among the most important mechanisms in the pathogenesis of dry eye disease (DED), triggering the vicious circle of the disease. Reducing inflammation is an important target in dry eye disease treatment. Hydrocortisone is a low-potency corticosteroid with a low ocular penetration potential.
