The effect of pulse steroid treatment of ten days’ long on the improvement of bacillary layer detachment in a patient with Vogt-Koyanagi Harada disease

Purpose: To illustrate the improvement pattern of bacillary layer detachment (BLD) in a closely monitored patient with Vogt-Koyanagi-Harada (VKH) disease. Methods: Imaging with color fundus photography and spectral domain optical coherence tomography (SD-OCT). Results: The pattern of BLD was noticed better with each passing day under the treatment of ten days’ long pulse methylprednisolone (1 g/ day) therapy. Though a meaningful decrease in size and shape of the BLD occurred on the eight day of pulse treatment, it showed resolution at two weeks follow-up, but the associated subretinal serous fluid persisted until the sixth week of treatment. Conclusion: The term BLD has become a widely used description as an OCT finding in some diseases but its evolution with the treatment was less illustrated previously. Thereby, our aim was to share our observation of a patient with VKH disease having BLD, with the ophthalmic community.
