# Ultrasonographic study of the orbit as an early diagnostic tool in Vogt Koyanagi Harada disease (VKH): A case report

## TL;DR

This case report shows how ultrasound of the eye can help diagnose Vogt Koyanagi Harada disease early and distinguish it from similar conditions.

## Contribution

The paper highlights the novel use of orbital ultrasound as a non-invasive, early diagnostic tool for VKH disease.

## Key findings

- Ultrasonography can detect early signs of VKH disease in the orbit.
- Ultrasound helps differentiate VKH from other similar diseases with distinct treatment needs.
- Early diagnosis via ultrasound allows timely treatment and better outcomes.

## Abstract

In recent years, ultrasound has demonstrated its usefulness in the approach to vascular structures and other tissues such as the orbit, facilitating the early diagnosis of various diseases without having to rely on other more invasive or less available tests. In Vogt Koyanagi Harada syndrome, characterised by bilateral acute uveitis, ocular ultrasound is a clear example of the usefulness of ultrasonography in early diagnosis, facilitating the initiation of specific treatment to change the ominous natural history of this disease. This case shows the usefulness of the echography to make the differential diagnosis with other diseases that clinical onset could be similar than VKH, but with a different diagnostic and therapeutic approach.
