Representative plots from one normal cat designated as a non-responder (A–C) and one normal cat designated as a mild responder (D–F), before (A,D), during (B,E) and after (C,F) topical corticosteroid therapy. Baseline IOP data shows consistency in IOP between the right and left eyes (A and D). The red arrow highlights the onset of the prednisolone acetate arm. Following withdrawal of topical corticosteroid treatment (C and F) IOP rapidly returned to baseline after cessation of corticosteroid treatment (F).
