PURPOSE: This study reports a case of interpupillary distance (IPD) shortening after instillation of topical prostaglandin analog (PGA) eye drops. OBSERVATIONS: The patient was a 36-year-old ophthalmic vitreoretinal surgeon from Tochigi, Japan, with primary open-angle glaucoma and bilaterally instilled PGA eye drops to decrease intraocular pressure. His IPD had been recorded closely based on surgical microscope settings. The patient had a stable IPD for over five years before the use of PGA drops. The patient noticed IPD shortening associated with latanoprost usage since four years. The IPD shortened further twice with temporal switching to bimatoprost. However, the IPD partially recovered both the times on discontinuing the medication over the course of several months. CONCLUSIONS AND IMPORTANCE: Fluctuations in IPD with visible cosmetic changes occur in association with the use of topical PGA eye drops. There might be effects of PGA drops on binocular vision, which are possibly unaddressed and warrant further study.
