Hypopyon: Is-it Infective or Noninfective?

Hypopyon usually corresponds to the sedimentation of white blood cells, and it signifies severe intraocular inflammation. This key clinical sign may occur in association with a wide variety of infectious, inflammatory, and neoplastic conditions that may be sight- and, occasionally, life-threatening. A careful history and thorough clinical examination are the cornerstones for orienting the differential diagnosis, identifying the causative agent, and initiating prompt and appropriate treatment.

Purpose: To describe swept source-OCT (SS-OCT) and swept source-OCT angiography (SS-OCTA) findings in eyes with posterior microphthalmos (PM).

Methods: Twelve eyes (six patients) with PM were evaluated using SS-OCT and SS-OCTA. Structural changes, subfoveal choroidal thickness (SFCT), and perifoveal capillary changes with qualitative and quantitative assessments were analyzed.

Atypical white dot syndrome with choriocapillaris ischemia in a patient with latent tuberculosis.

Background: White dot syndromes (WDS) are a group of idiopathic multifocal inflammatory conditions that can be recognized and distinguished by lesion morphology, other specific clinical features, imaging findings, and disease course. Our purpose is to describe an atypical case of WDS with choriocapillaris ischemia shown by multimodal imaging including swept-source OCT angiography (OCTA) in a 30-year-old woman with latent tuberculosis.

Findings: At presentation, visual acuity in the left eye was 20/500.
