Dexmedetomidine Moderate Sedation Versus General Anesthesia on the Diagnostic Yield of Endobronchial Ultrasound-Guided Transbronchial Needle Aspiration: A Randomized Controlled Study.

Background: One of the factors that affect the diagnostic yield of endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is the level of sedation.

Objectives: Therefore, we aimed to compare dexmedetomidine (DEX) as moderate sedation (MS) versus general anesthesia (GA) on the diagnostic yield of EBUS-TBNA.

Methods: This randomized open-label controlled trial was carried out on 70 patients older than 18 years of age, classified as American Society of Anesthesiologists (ASA) II or III, and scheduled for EBUS-TBNA.

Posterior Segment Involvement in Childhood Presumed Trematode Induced Granulomatous Anterior Uveitis.

Purpose: To outline posterior segment characteristics of presumed-trematode induced granulomatous uveitis.

Design: A cross-sectional case series.

Methods: The study included 56 patients (60 eyes) presented with anterior chamber (AC) granulomas.

Visual performance following implantation of presbyopia correcting intraocular lenses.

Objective: To compare the visual outcomes following bilateral implantation of 3 presbyopia correcting IOLs.

Methods: Results are reported for patients who underwent phacoemulsification with bilateral implantation of one of the following IOLs: Panoptix IOL, AT LISA tri IOL and Symphony IOL. Six months postoperative examination included monocular UIVA at 80 and 60 cm and monocular UNVA and DCNVA at 40 cm, monocular UDVA and CDVA, Spherical equivalent (SE) refraction, binocular defocus curve, contrast sensitivity, photopic phenomena, and spectacle independence.
