From Blurred Vision to Hearing Loss: Recognizing the Symptoms of VKH Syndrome
Early recognition of the diverse symptoms of Vogt-Koyanagi-Harada (VKH) syndrome is crucial for timely diagnosis and initiation of treatment, which can significantly impact the long-term prognosis, particularly for vision and hearing. The constellation of symptoms can vary in onset and severity among individuals, but understanding the typical progression "from blurred vision to hearing loss" and beyond is essential for both patients and healthcare providers.

The initial symptoms of VKH syndrome often involve the eyes. Patients typically experience blurred vision in both eyes, which can develop gradually or relatively suddenly. This may be accompanied by eye pain, a deep ache or discomfort, and redness of the eyes. Photophobia, or increased sensitivity to light, is another common early symptom, making bright environments uncomfortable. Some individuals may also notice floaters, small dark spots or lines that seem to drift across their field of vision. These ocular symptoms reflect the initial inflammatory attack on the uveal tract.
Following the initial ocular phase, or sometimes concurrently, patients may develop other systemic symptoms. Headache is frequently reported and can be severe. Nausea and vomiting may also occur. These systemic symptoms are thought to be related to meningeal inflammation, a less common but recognized aspect of VKH syndrome.
A characteristic feature of VKH syndrome is the involvement of the auditory system. Patients may experience tinnitus, often described as a ringing, buzzing, or roaring sound in the ears. Hearing loss, typically bilateral and sensorineural (affecting the inner ear), can develop. Some individuals may also experience vertigo, a sensation of dizziness or spinning, indicating involvement of the vestibular system in the inner ear. The onset of these auditory symptoms can occur around the same time as the ocular symptoms or several weeks later.
Integumentary (skin and hair) changes are another important aspect of VKH syndrome, although they often appear weeks or months after the initial ocular symptoms. Vitiligo, the development of patches of depigmented skin, can occur on various parts of the body. Poliosis, the whitening of the hair, is particularly noticeable when it affects the eyelashes, eyebrows, and scalp hair. Alopecia, or hair loss, can also occur. These dermatological manifestations are a result of the autoimmune attack on melanocytes in the skin and hair follicles.
The progression of symptoms can vary. Some patients may experience a relatively rapid onset of all the characteristic features, while others may have a more gradual or sequential presentation. It is important to note that not all patients will develop every single symptom of VKH syndrome.
Recognizing the interconnectedness of these seemingly disparate symptoms – from the initial blurred vision and eye pain to subsequent hearing loss and skin changes – is key to suspecting VKH syndrome. A high index of suspicion, particularly in individuals from higher-risk ethnic groups presenting with bilateral uveitis and associated systemic findings, is crucial for prompt referral to specialists for diagnosis and treatment. Educating patients and healthcare providers about the diverse manifestations of VKH syndrome can lead to earlier diagnosis and ultimately better outcomes.
