A case report combined with a literature review was conducted. A 19-year-old male developing VKH after receiving the second dose of an inactivated COVID-19 vaccine was analyzed. Clinical features, treatment outcomes (glucocorticoid therapy with 2-year follow-up), and literature-based comparisons were evaluated. PubMed-indexed cases of vaccine-associated VKH were systematically reviewed, and causality was assessed using the Naranjo Adverse Drug Reaction Probability Scale. The patient presented with bilateral blurred vision 14 days post-vaccination, diagnosed as VKH with retinal neuroepithelial detachment via fluorescein angiography (FFA) and optical coherence tomography (OCT). Oral prednisone (starting at 60 mg/day, tapered gradually)restored visual acuity to near-normal levels (OD: 20/40, OS: 20/33), consistent with the patient's reported baseline vision.

Literature analysis revealed vaccine-associated VKH symptoms typically emerged at a median of 8 days post-vaccination, aligning with the WHO's 40-day adverse event monitoring window. A Naranjo score of 4 indicated a probable vaccine-triggered immune response. COVID-19 vaccines may induce VKH via immune dysregulation mechanisms, particularly in genetically predisposed individuals.

Furthermore, there is growing evidence of the role of autoimmunity in a subset of POTS cases. In recent years, investigators have described an increased rate of autoimmune comorbidities as evidenced by the finding of several types of neural receptor autoantibody and non-specific autoimmune marker in patients with POTS. In particular, the association of the disease with several types of anti-G protein-coupled receptor (GPCR) antibodies and POTS has frequently been noted.
