Direct injection of air into the macular fold may represent an effective strategy to enhance the surgical management of such a vision-threatening complication. Air also minimizes the risks related to the forceful injection of fluid under the macula. An overview of recently reported surgical techniques is included, along with a brief discussion.
Our study gives new information on the aspect and the location of crystal deposits in the choroid and the abnormalities of the outer retina associated with the disease.
Background/Purpose: To determine which retinal layer is primarily involved in intraretinal vascular processes associated with Toxoplasma retinochoroiditis using multimodal imaging, including optical coherence tomography angiography (OCTA).Methods: Toxoplasma retinal lesions were analyzed through multimodal imaging, including color fundus photographs, fluorescein angiography, indocyanine green angiography, spectral-domain OCT, and OCTA.Results: Two patients with atypical features of Toxoplasma retinochoroiditis are described in the acute phase. The first patient presented with a primary episode of acute Toxoplasma retinitis associated with an intraretinal abnormal vascular process that was detected at the acute phase by indocyanine green angiography and was better delineated by OCTA. Seven months later, the intraretinal vascular process had fully resolved on OCTA imaging. The second patient presented with a recurrence of active Toxoplasma retinochoroiditis adjacent to a pre-existing pigmented scar. He had a similar abnormal intraretinal vascular process that was identified on both fluorescein angiography at the early phase and indocyanine green angiography, which was also confirmed by OCTA imaging.Conclusion: We report a new finding associated with Toxoplasma chorioretinitis: an abnormal intraretinal vascular process that resolved without anti-vascular endothelial growth factor therapy but after toxoplasmosis treatment alone.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
