Climate change is viewed as the primary threat to coral reefs, with local pressures exacerbating coral cover decline. The consensus is that improving water quality may increase resilience, but disentangling water quality and temperature impacts is difficult. We used distance-based linear models and random forests to analyze spatiotemporal variation in benthic community structure and interannual changes in the coral assemblage, in relation to specific environmental metrics in Southeast Florida.

Article Synopsis
  • The study aimed to evaluate and create consensus guidelines among global uveitis specialists regarding the management of herpes simplex virus (HSV) and varicella-zoster virus (VZV) associated anterior uveitis (AU).
  • An online Delphi survey gathered responses from 76 uveitis experts across 21 countries, with findings leading to the establishment of treatment guidelines via the TITAN working group.
  • Key conclusions highlighted specific diagnostic signs for HSV and VZV AU, preferred use of valacyclovir for treatment, and a variety of opinions on treatment duration and managing recurrences.

Article Synopsis
  • Noninfectious uveitis (NIU) in children is a rare but treatable condition that can lead to vision loss, necessitating careful monitoring and management.
  • Treatment options include systemic methods like corticosteroids and disease-modifying drugs, with a stepwise approach being common; methotrexate is the preferred conventional drug, while adalimumab is the only approved biological treatment for kids.
  • Managing pediatric NIU requires a multidisciplinary team to address medical, psychological, and supportive needs, including dealing with potential side effects and treatment responses.

Purpose: To describe and illustrate recent reclassification and clinical descriptions of the histiocytoses, diagnosis and management, and effects on the eye and adnexae.

Patients And Methods: Literature review with an illustrative case series of seven patients with histiocytosis and ophthalmic involvement from a single tertiary centre.

Results: Skin lesions with signs including eyelid mass, orbital bone destruction, bizarre keratic precipitates, limbal or iris mass, haemorrhagic anterior uveitis, subretinal lesions of uncertain etiology, ischaemic retinopathy, optic neuropathy, and apparent steroid-resistant inflammations should be comprehensively investigated.

Rare species population dynamics can elucidate the resilience of an ecosystem. On coral reefs, climate change and local anthropogenic stressors are threatening stony coral persistence, increasing the need to assess vulnerable species locally. Here, we monitored the threatened pillar coral, Dendrogyra cylindrus, population in southeast Florida, USA, in relation to consecutive heat stress events in 2014 and 2015.

Long-acting, slow-release injectable fluocinolone intravitreal implants have been approved for the treatment of non-infectious uveitis affecting the posterior segment. We summarise the development of intravitreal fluocinolone implants and discuss the technology including pharmacokinetics. We conducted a systematic review of evidence for the efficacy, safety and patient acceptability of fluocinolone 0.

Purpose: Automated measurement algorithm software is not routinely available in optical coherence tomography angiography (OCTA) devices and manual measurement of choroidal neovascular membrane (CNVM) size is necessary. Our aim was to determine intra- and inter-rater agreement of inflammatory CNVM manual measurements obtained with OCTA.

Methods: OCTA (Triton® Topcon Corporation) images in patients with inflammatory CNVM were imported into ImageJ software v1.

Purpose: To describe the antimicrobial effects of immunosuppressants used for presumed autoimmune uveitis, and to discuss the potential importance of these effects in the context of increasing knowledge of the human microbiomes and their influence on inflammation.

Methods: Literature review.

Review Of Evidence: All immunosuppressants have intrinsic antimicrobial effects; these vary considerably between drugs, and include antibacterial, antiviral and antifungal action.

Background: Primary vitreoretinal lymphoma (PVRL) is a rare ocular condition and its diagnosis remains a challenge. The clinical presentation is variable and it can masquerade as chronic intermediate or posterior uveitis. We report an unusual case of primary central nervous system lymphoma (PCNSL) presenting as migrating retinal lesions with unique shapes.

This study investigated the efficacy and safety of Baerveldt glaucoma implants (BGI) in adults with uveitic glaucoma (UG) at the Manchester Uveitis Clinic. This was a retrospective study of 42 patients with UG who underwent BGI implantation between 2006 and 2015. Primary outcome measures were intraocular pressure (IOP) reduction and number of medications at 5-year follow-up.

: To evaluate multimodal imaging findings in longitudinal follow-up of a patient with presumed tuberculous serpiginous-like choroiditis (TB-SLC). : We evaluated multimodal imaging in a 62-year-old male with TB-SLC. Correlation between optical coherence tomography angiography (OCTA), swept-source OCT (SS-OCT) and fundus autofluorescence (FAF) at defined disease stages and evolution of observed imaging descriptors during long-term follow-up has not been previously reported.
