Abstract
Summary & Conclusion
Posterior uveitis is a sight threatening condition worldwide
particularly among the working-age population. It may be the first
presentation of serious systemic disease and be a vital warning sign that
allows early diagnosis and medical intervention.
Etiologically, posterior uveitis may be the result of infectious, noninfectious
with or without systemic involvement or ‘masquerade’ causes
as described by the international uveitis study group (IUSG).
Noninfectious uveitis with no associated systemic disease or other
precipitant is termed ‘idiopathic’. Posterior uveitis as described by the
standardization of uveitis nomenclature (SUN) may be focal, multifocal,
or diffuse with involvement of posterior segment structures such as
choroid, retina, retinal blood vessels and optic nerve head.
Due to a wide variety of phenotypic features, the diagnostic
approach is not that simple including careful history taking,
comprehensive review of systems, précised ocular examination, targeted
laboratory workup, and tailored ocular imaging.
Retinal & choroidal imaging is very important in diagnosing
pathologies and monitoring inflammatory process and treatment of
posterior uveitis. Fundus fluorescein angiography (FFA) and optical
coherence tomography (OCT) are the most commonly used imaging
techniques.
This prospective, controlled, selective, cross-sectional study aimed
to evaluate chorioretinal changes in eyes with newly diagnosed
