Bilateral Acute Iris Transillumination (BAIT) and Elevated Intraocular Pressure after COVID 19 Infection.

Bilateral acute iris transillumination (BAIT) is characterized by abundant pigment discharge into the anterior chamber. Atonic pupil and severe intraocular pressure elevations may be observed. Generally, there is a viral upper respiratory tract infection or systemic fluoroquinolone usage before BAIT. Two cases with a recent history of Covid-19 presented with a complaint of decreased vision. Elevated intraocular pressure (IOP) and iris transillumination defects were observed in both patients. Both patients were diagnosed with BAIT. Although elevated IOP was controlled with medical treatment in one patient, glaucoma surgery was performed in the other patient because it could not be controlled with medical treatment. Since both patients received no systemic treatment for the Covid-19, the pressure rise seems to be directly related to the viral infection alone through the inflammatory process. Atypical ocular presentations of Covid-19 should be kept in mind as it can have serious consequences.
