Vogt-Koyanagi-Harada (VKH) syndrome is a rare bilateral granulomatous panuveitis typically affecting the more pigmented races, and women more than men. VKH syndrome is theorized due to a T-cell-mediated autoimmune reaction against antigens related to melanin and melanocytes, that may happen due to cutaneous or viral triggers. Along with the clinical evaluation, it is mandatory to utilise additional investigative modalities such as fundus fluorescein angiography (FFA), indocyanine green angiography (ICGA), optical coherence tomography (OCT) and ultrasonography, which will help pick up pathognomonic signs, that can be missed on clinical evaluation. In this manuscript, we have reported striking multimodal images of a VKH patient with poor adherence; and have emphasized early detection, initiation of therapy without delay, aggressive therapy, good compliance, very slow tapering of oral steroids and use of immunosuppressants for a good visual prognosis.

A 35-year-old female patient came to the outpatient department with a sudden loss of vision in her left eye (OS). On evaluation, the right eye (OD) was within normal limits [Figure 1]a with best corrected visual acuity (BCVA) of 20/20, and OS revealed a normal anterior segment with multiple pockets of subretinal fluids (SRF) all over the posterior pole [Figure 1]b, with BCVA of 20/60. Optical coherence tomography (OCT) revealed multiple SRF pockets, increased choroidal thickness and retinal pigment epithelial (RPE) undulations [Figure 1]c and [Figure 1]d with all classical features of Vogt-Koyanagi-Harada (VKH) syndrome. A set of tailored blood investigations were done to rule out other systemic causes and was found to be within normal limits. The patient was a known diabetic on treatment, with no other systemic illness or history of trauma. As the VKH syndrome was in its acute phase, intravenous (IV) methylprednisolone 1 gram over 1 hour was administered under a physician's supervision for 3 days, after contraindications to it were ruled out, followed by high-dose systemic oral prednisolone 60 mg/day.

Following therapy, there was a resolution of VKH features [Figure 2]a but subtle RPE undulations [Figure 2]b and disc oedema [Figure 2]c developed in OS, which were not present on the previous visit. Fundus fluorescein angiography (FFA) with indocyanine green angiography (ICGA) was performed [Figure 3] and [Figure 4] during the next visit. The patient also started developing bilateral anterior uveitis with cells 2+ and flare 1+, for which she was started on topical steroids along with systemic oral prednisolone 60 mg/day (i.e., 1 mg/kg body weight as the weight of the patient was 60 kg). The BCVA improved to 20/20 in OS with a resolution of signs at 2-month follow-ups. However, the patient had poor medication adherence and she subsequently developed multiple SRF pockets in OD [Figure 5]. The patient was advised to restart her medications and was put additively on an immunosuppressive agent (Azathioprine 50 mg/day).

In this manuscript, we have reported a striking multimodal imaging canvas of a case of VKH syndrome, which developed in OS initially and later involved OD due to poor adherence to medications. Immunosuppressants were added later in this case; however, some clinicians carry an opinion to start immunosuppressants with steroids at the initial presentation of VKH syndrome. Also, as the patient was a known diabetic, an early start with an immunosuppressant with intravitreal dexamethasone implant is another school of thought for treating this patient, thus reducing the systemic dosage of steroids.
Nevertheless, the patient showed a good prognosis when compliant with therapy. The visual prognosis of VKH is dependent on the duration and number of recurrent episodes of inflammation, the number of complications, age at disease onset, the median duration of the disease and time of initiating therapy.,,, Better the visual acuity at presentation, more likely the final visual acuity is to improve, as seen in this case.,
