Purpose: To describe the use of hyperbaric oxygen therapy (HBOT) in conjunction with immunosuppression for acute macular neuroretinopathy (AMN) in systemic lupus erythematosus (SLE).

Methods: Two known cases of SLE presented to us with blurred vision and paracentral scotomas due to AMN. Both cases reported worsening of their conditions despite the initiation of high-dose steroid therapy.

Purpose: To report endogenous fungal endophthalmitis, postrecovery from severe COVID-19 infection in otherwise immunocompetent individuals, treated with prolonged systemic steroids.

Methods: Retrospective chart review of cases with confirmed and presumed fungal endogenous endophthalmitis, following severe COVID-19 disease, treated at two tertiary care referral eye institutes in North India.

Results: Seven eyes of five cases of endogenous fungal endophthalmitis were studied.

Tubercular intermediate uveitis (TIU) and panuveitis (TBP) are difficult to manage because of limitations in diagnostic tools and lack of evidence-based treatment guidelines. The Collaborative Ocular Tuberculosis Study (COTS) analyzed treatment regimens and therapeutic outcomes in patients with TIU and TBP. Multicentre retrospective analysis.

An international, expert led consensus initiative was set up by the Collaborative Ocular Tuberculosis Study (COTS) group to develop systematic, evidence, and experience-based recommendations for the treatment of ocular TB using a modified Delphi technique process. In the first round of Delphi, the group identified clinical scenarios pertinent to ocular TB based on five clinical phenotypes (anterior uveitis, intermediate uveitis, choroiditis, retinal vasculitis, and panuveitis). Using an interactive online questionnaires, guided by background knowledge from published literature, 486 consensus statements for initiating ATT were generated and deliberated amongst 81 global uveitis experts.

Multimodal imaging relies on combination of multiple imaging modalities to precisely delineate pathological changes in the posterior segment of the eye associated with a wide range of conditions. This combined application of fundus photography, optical coherence tomography, fundus reflectance/autofluorescence and fundus angiography (with fluorescein, indocyanine green and/or optical coherence tomography) is of great utility for assessment of patients with ocular toxoplasmosis. Multimodal imaging is helpful to characterize the typical pattern of toxoplasmic retinochoroiditis, with primary focal inflammatory involvement of the neurosensory retina, and secondary changes at the level of underlying choroid, retinal blood vessels, vitreous and even optic disc.

Tuberculosis (TB) is a major infection that can affect the eye as first and sole presentation without features of systemic disease. Controversy exists regarding diagnosis and management of tubercular uveitis (TBU), further compounded by regional variations in disease expression. Collaborative Ocular Tuberculosis Study (COTS)-1 aims to address knowledge deficits through collaboration amongst uveitis specialists across the globe by sharing the data of patients with TBU presented at participating centers from January 2004 to December 2014.
