Introduction

In an exciting breakthrough for ophthalmology, researchers have identified a new ultrasound feature, dubbed the “Triangle sign,” which could significantly enhance the accuracy in diagnosing total choroidal detachments (CHs) and suprachoroidal hemorrhages (SCHs). This innovative finding has been led by Dr. Vaidehi D. Bhatt from the UBM Institute in Mumbai, India, alongside experts from Rajan Eye Care Pvt. Ltd. in Chennai and the University Eye Clinic Maastricht in the Netherlands.

What is the Triangle Sign?

The Triangle sign is described as a hypoechoic or anechoic triangular shape of the vitreous located just anterior to the optic disc in cases exhibiting a total choroidal detachment. This discovery is pivotal, as CHs are medical conditions characterized by the choroidal separation from the sclera, often presenting varied symptoms including both serous and hemorrhagic occurrences.

Understanding Choroidal Detachments and Hemorrhages

Dr. Bhatt and her team noted that serous detachments typically arise from fluid buildup in the suprachoroidal space stemming from factors like hypotony, inflammation, or uveitis. In contrast, SCHs emerge from bleeding, indicative of more complex clinical scenarios that necessitate differentiation from other ocular disorders.

B-scan Analysis Breakthrough

In their retrospective study, the researchers evaluated the effectiveness of ultrasound B-scan examinations in revealing the Triangle sign, which they propose as a potential clinical tool to distinguish CHs and SCHs from other common ocular issues such as retinal detachments (RDs) and vitreous hemorrhages (VHs).

The study assessed a total of 36 eyes diagnosed with either a total CD or SCH. Remarkably, the Triangle sign was consistently observed across all cases. Notably, of the 31 cases of total SCH, about 58.1% were linked to prior intraocular surgeries while 41.9% were connected to post-traumatic events.

The team's findings highlighted the Triangle sign as a reliable indicator, noting that among the eyes with total SCH, 58.3% displayed a discernible choroidal membrane during B-scan assessments. This illustrates the feature's potential to aid in real-time monitoring of the condition, allowing clinicians to track changes as hemorrhages resolve.

Conclusion and Future Research

The researchers concluded that the Triangle sign stands out as a distinctive and dependable ultrasound characteristic for its role in diagnosing total CDs and SCHs. They emphasized its promise as a diagnostic tool that could offer clear anatomical and imaging distinctions, making the differentiation of CHs from other ocular pathologies much more streamlined.

However, the team advocates for further investigation through prospective, multicenter studies to validate the Triangle sign’s reliability. Such research is crucial to standardizing its use in clinical practice and to fully harness its potential as a diagnostic indicator in diverse medical environments.
