Systemic and Ocular Manifestations of Arboviral Infections: A Review.

Purpose: To provide an overview of pre-selected emerging arboviruses (arthropod-borne viruses) that cause ocular inflammation in humans.

Methods: A comprehensive review of the literature published between 1997 and 2023 was conducted in PubMed database. We describe current insights into epidemiology, systemic and ocular manifestations, diagnosis, treatment, and prognosis of arboviral diseases including West Nile fever, Dengue fever, Chikungunya, Rift Valley fever, Zika, and Yellow fever.

Ocular Manifestations After Acute Methanol Poisoning.

Acute methanol poisoning is first and foremost life-threatening. Otherwise, functional prognosis is mainly based on ocular impairment. In this case series we aimed to describe the ocular manifestations after acute methanol poisoning during an outbreak in Tunisia.

Swept-source Optical Coherence Tomography Angiography in Active and Scarred Toxoplasmic Retinochoroiditis.

Purpose: To describe optical coherence tomography angiography (OCTA) findings in eyes with active and scarred toxoplasmic retinochoroiditis.

Methods: OCTA scans in active (25 eyes) and scarred (17 eyes) retinochoroiditis were retrospectively reviewed.

Results: In active lesions, OCTA findings included a non-detectable flow signal area in retinal vascular plexuses and choriocapillaris in all 25 eyes (100%), an abnormal intraretinal vascular process in 2 eyes (8%), and an associated area of retinal flow deficit secondary to branch retinal artery occlusion in one eye (4%).

Comments on "Goyal M, Murthy SI and Annum S, Bilateral Multifocal Choroiditis following COVID-19 Vaccination".

The fundus photographs provided show deep yellowish lesions, multifocal exudative retinal detachments, and optic disc hyperemia in both eyes. Spectral domain optical coherence tomography scans shown demonstrate bilateral exudative retinal detachments involving the macula in the right eye. The exudative retinal detachment is characterized by the presence of subretinal fibrin and septa.
