AI Summary & Key Takeaways

AI Insight
⚡ TL;DR(Too Long; Didn't Read)

We herein report the optical coherence tomography (OCT) and OCT angiography (OCTA) fi ndings of the patient and discuss the association between the absence of the foveal pit on OCT and persistence of both superfi cial and deep capillary plexi at foveal center in OCTA; and aim to discuss the role of foveal pit and FAZ on visual acuity.

📌 3 Key Takeaways

🎯
Objective & Hypothesis:The patients with fovea plana have greater central foveal thickness accompanying with an extreme decrease or absence of the foveal avascular zone (FAZ).
📊
Key Findings & Data:We present a case of bilateral idiopathic isolated fovea plana who has been diagnosed during routine ophthalmic examination.
💡
Conclusion & Impact:We herein report the optical coherence tomography (OCT) and OCT angiography (OCTA) fi ndings of the patient and discuss the association between the absence of the foveal pit on OCT and persistence of both superfi cial and deep capillary plexi at foveal center in OCTA; and aim to discuss the role of foveal pit and FAZ on visual acuity.
