Abstract
BACKGROUND AND OBJECTIVE
To describe the multimodal imaging characteristics associated with punctate outer retinal toxoplasmosis (PORT).
PATIENTS AND METHODS
Multicenter, retrospective, observational case series of three patients who presented with PORT. Multimodal imaging was reviewed including optical coherence tomography (OCT), fundus autofluorescence, optical coherence tomography angiography, and conventional dye-based angiography.
RESULTS
Patient ages ranged from 13 years to 55 years. Each patient had multiple white, punctate outer retinal lesions in the affected eye at initial diagnosis. OCT showed both inner and outer retinal changes, including disruption of the ellipsoid and interdigitation zones and retinal pigment epithelium/Bruch's membrane complex, as well as punctate, preretinal, hyperreflective lesions at the vitreoretinal interface, which regressed with treatment.
CONCLUSION
Multimodal imaging is useful in diagnosing and monitoring treatment response in PORT, an uncommon presentation of ocular toxoplasmosis that must be differentiated from white dot syndromes or other causes of unilateral retinitis. [Ophthalmic Surg Lasers Imaging Retina. 2019;50:281-287.].
