Choroidal Cavitary Disorders

Area of Science:

• Ophthalmology
• Retinal Imaging
• Choroidal Pathophysiology

Background:

• The choroid's structure and function are known, but its anomalies' pathophysiology was unclear before optical coherence tomography (OCT).
• Choroidal cavitations, appearing as optically empty spaces, are associated with outer retinal layer attenuation or loss.
• These cavitations occur in the posterior pole and are observed in conditions like pathologic myopia, North Carolina Macular Dystrophy (NCMD), focal choroidal excavation (FCE), and torpedo maculopathy (TM).

Purpose of the Study:

• To describe the differences and similarities of choroidal cavitation across various retinal disorders.
• To highlight the common underlying malformation of the RPE-photoreceptor-choroid complex in these conditions.
• To emphasize the role of multimodal imaging in detecting and managing potential complications.

Main Methods:

• Utilized optical coherence tomography (OCT) for high-resolution imaging of choroidal structures.
• Analyzed OCT findings in patients with pathologic myopia, NCMD, FCE, and TM.
• Correlated imaging findings with clinical presentations and potential complications.

Main Results:

• Choroidal cavitations are a shared feature in distinct retinal disorders, previously unlinked.
• These conditions share a common pathophysiology involving malformation of the RPE-photoreceptor-choroid complex.
• OCT imaging provides detailed visualization of choroidal cavitations and associated retinal changes.

Conclusions:

• Choroidal cavitation represents a common link between seemingly disparate retinal disorders.
• Multimodal imaging, particularly OCT, is crucial for accurate diagnosis and management.
• Understanding the shared pathophysiology aids in predicting and mitigating complications.
