Bryophyte Flora of AlUla County (Saudi Arabia)-Distribution, Ecology, and Conservation.

Intensive surveys recently conducted in AlUla County (northwest Saudi Arabia) have made it possible to compile an exhaustive list of the forty-eight bryophyte species (six liverworts and forty-two mosses) known in this region and compare it with an updated checklist of bryophytes from Saudi Arabia, which now counts 31 liverworts and 135 mosses. The ecology, taxonomy, and distribution of each taxon are provided and discussed in a systematic catalog. Although particularly arid and lacking permanent watercourses, AlUla County has proven to be surprisingly rich in bryophytes.

Etiology of hypopyon in patients presenting acutely to the emergency eye department and characteristics of hypopyon uveitis.

Objective: To examine the etiology of undifferentiated hypopyon presenting acutely and to better characterize hypopyon uveitis.

Methods: Patients with hypopyon were retrospectively identified from presentations to the emergency eye department between January 2015 and 2022 and also from a uveitis database of 3,925 patients seen between January 2008 and January 2022. A total of 426 episodes of hypopyon occurred in 375 eyes in 359 patients, and medical records were reviewed for each patient.

Role of screening for uveitis in subjects with sarcoidosis.

Background And Objectives: Ocular involvement is common in sarcoidosis. Our study aimed to evaluate the role of screening for uveitis in subjects with sarcoidosis.

Methods: Retrospective case series of 88 subjects with a pre-existing diagnosis of sarcoidosis, with no previous diagnosis of uveitis, reviewed by Ophthalmology at Auckland District Health Board between January 2016 and May 2022.

Diabetes Mellitus Related Anterior Uveitis - An Overlooked Clinical Entity.

Background: This study aimed to evaluate the characteristics of anterior uveitis in patients presenting with poorly controlled diabetes mellitus and with no other identifiable cause for their uveitis.

Methods: A retrospective study of 121 eyes in 89 patients who presented at Auckland District Health Board with idiopathic acute anterior uveitis and uncontrolled diabetes between September 2009 and January 2022.

Results: The diagnosis of diabetes mellitus was known prior to presentation in 80 subjects (89.
