IOTM: Toxoplasmosis Retinochoroiditis
A 57-year-old Indian female with a prior history of posterior uveitis was referred for scarring OD. BCVA 20/20 OU, diagnostic testing demonstrated +IgG antibodies to toxoplasmosis, IgM was negative.
IOTM: Branch Retinal Artery Occlusion
This 52 year-old patient presented with a sudden central visual field defect in the right eye for two days. Visual acuity, intraocular pressure and anterior segment were unremarkable. Visual field testing revealed a horizontal circumscribed defect from the optic nerve, beyond the macula, inferior to the fovea. (Image A) Fundus photography demonstrated an occlusion of a cilioretinal artery (branch retinal artery occlusion). (Image B) The horizontal SS-OCT (Image C) and vertical SS-OCT (Image D) through the branch retinal artery occlusion clearly demonstrate retinal ischemia.
IOTM: Choroidal Nevus with Drusen
This 52 year-old patient presented with a sudden central visual field defect in the right eye for two days. Visual acuity, intraocular pressure and anterior segment were unremarkable. Visual field testing revealed a horizontal circumscribed defect from the optic nerve, beyond the macula, inferior to the fovea. (Image A) Fundus photography demonstrated an occlusion of a cilioretinal artery (branch retinal artery occlusion). (Image B) The horizontal SS-OCT (Image C) and vertical SS-OCT (Image D) through the branch retinal artery occlusion clearly demonstrate retinal ischemia.

IOTM: Sub-hyaloid Hemorrhage
This case shows the benefits of using Swept Source OCT technology when imaging through media opacities such as sub-hyoidal hemorrhaging.
IOTM: Suprachoroidal ILUVIEN® Implant for DME
This is a patient with Chronic Diabetic Macular Edema. The patient received several anti VEGF injections; the need of reinjection was a problem.
IOTM: Proliferative Diabetic Retinopathy “Wolf Jaw” with Vitreous Cysts
This is a patient with Chronic Diabetic Macular Edema. The patient received several anti VEGF injections; the need of reinjection was a problem.
IOTM: Optic Nerve Head Drusen (ONHD)
This patient presented with an elevated optic nerve. To help distinguish between calcified optic disc drusen vs. optic disc edema, fundus autofluorescence (Image B) successfully shows calcified optic disc drusen of the nerve head. The Triton’s capability to simultaneously show true color fundus photos (Image A), fundus autofluorescence (Image B), and OCT (Image C) makes the patient’s presentation clear without the need for further imaging.
