Ocular Surface Homeostasis After Scleral Lens Usage.

OBJECTIVES: The aim of this prospective study is to examine the effects of 5 hours of well-fitted, mini-scleral contact lens (mini-SL) wear on the tear film cytokine expression in healthy eyes. METHODS: Twenty-three healthy participants were included in the study. One eye of each participant was selected at random, and a mini-SL measuring 16.5 mm in diameter was fitted by an experienced contact lens specialist. The contact lens remained in place for 5 hours. Precorneal tear fluid was collected using capillary tubes at three different time points: baseline before SL insertion (T0), after 5 hours of SL wear (T1), and 3 hours after SL removal (T2). The concentration of 40 inflammatory cytokines at the three different time points was determined using multiplex bead assay. RESULTS: Mini-scleral lens wear did not result in significant changes in the cytokine-to-protein ratio after 5 hours of wear on a healthy eye. CONCLUSIONS: Although a well-fitted mini-SL reduces the rate at which the precorneal tear film is refreshed, 5 hours of lens wear did not appear to significantly affect the tears cytokine-to-protein ratio, suggesting that scleral lenses have minimal impact on corneal cytokine expression.

Testicular Sarcoidosis: Diagnostic Approach and Management Strategies.

Sarcoidosis is a multisystem disorder which, in rare cases, can affect the urogenital tract. The clinical presentation of this benign inflammatory disorder can easily mimic that of testicular malignancy. Therefore, it is crucial to differentiate between these two entities, as misdiagnosis may lead to unnecessary surgical interventions, which have important implications for future fertility. While testicular cancer must always be ruled out, sarcoidosis should be considered in all patients presenting with a testicular mass. Here, we present a case of sarcoidosis with bilateral epididymal and testicular involvement. The diagnosis was made by frozen section and the patient was treated with corticosteroids.
