Indocyanine green angiography in posterior uveitis

Area of Science:

• Ophthalmology
• Medical Imaging
• Inflammatory Diseases

Background:

• Posterior uveitis encompasses diverse inflammatory chorioretinal conditions.
• Accurate diagnosis is crucial for effective management and visual preservation.
• Established imaging modalities like fluorescein angiography have limitations in certain cases.

Purpose of the Study:

• To evaluate the diagnostic role of indocyanine green angiography (ICGA) in posterior uveitis.
• To review the literature and analyze ICGA findings in various posterior uveitis subtypes.
• To assess ICGA as an adjunctive tool for diagnosing inflammatory chorioretinal disorders.

Main Methods:

• Comprehensive literature review on ICGA in uveitis.
• Retrospective analysis of medical records for patients with posterior uveitis.
• Inclusion of patients who underwent both fundus examination and ICGA.

Main Results:

• ICGA demonstrated characteristic hypofluorescent dark spots in various posterior uveitis types.
• Specific patterns were observed in serpiginous choroiditis, ampiginous choroiditis, and other conditions.
• ICGA provided additional diagnostic information beyond standard fundus examination.

Conclusions:

• Indocyanine green angiography is a valuable adjunctive tool for diagnosing inflammatory chorioretinal diseases.
• ICGA complements fluorescein angiography by offering unique insights into choroidal inflammation.
• Further research is needed to determine ICGA's utility in monitoring disease progression.
