SCLERAL EXCAVATION AT OBLIQUE MUSCLE INSERTIONS: IMAGING CHARACTERISTICS AND CORRELATION WITH SCLERAL PLAQUES AND SCLEROCHOROIDAL CALCIFICATION [Case Report]

Cabral, Diogo; Fisher, Yale L; Freund, K Bailey
PURPOSE/OBJECTIVE:To compare the imaging features of lesions showing hyporeflective posterior scleral excavation found near the insertions of the oblique extraocular muscles to the features and the natural course of Cogan scleral plaques. METHODS:Multimodal imaging with color fundus photography, spectral-domain optical coherence tomography (OCT), swept-source optical coherence tomography, and B-scan ultrasonography. RESULTS:A 71-year-old man and an 89-year-old man presented with ring-shaped hypopigmented lesions measuring between 200 μm and 300 μm transversally, and located along the superior vascular arcade and temporal to the fovea. All lesions were identified near the insertion of oblique muscles, with one observed in the temporal macula, and two found along the superotemporal arcades. Enhanced depth imaging-optical coherence tomography showed hyporeflective boat-shaped areas of scleral excavation with reduced choroidal thickness along their margins. B-scan ultrasonography showed the lesions to be intensely reflective with varying degrees of posterior shadowing. CONCLUSION/CONCLUSIONS:To our knowledge, this is the first report of excavated hyporeflective scleral lesions found near the oblique muscle insertions. Imaging and clinical data support the diagnosis of a posterior form of Cogan scleral plaque and are consistent with the natural course of this entity.

Presumed retinal pericapillary astrocytic hamartoma: multimodal imaging findings of a novel hamartomatous lesion

Ledesma-Gil, Gerardo; Essilfie, Juliet; Onishi, Alex; Wald, Kenneth J; Fisher, Yale L; Fawzi, Amani A; Shields, Carol L; Freund, K Bailey; Chhablani, Jay
PURPOSE/OBJECTIVE:To describe the multimodal imaging findings of retinal lesions that clinically resemble retinal astrocytic hamartomas (RAHs), but also have unique characteristics that we believe represent a novel variant. METHODS:Observational study. Five eyes in five patients with solitary retinal lesion evaluated at the retina division of three institutions. We describe the multimodal imaging findings including fundus photography, fundus autofluorescence, fluorescein angiography, spectral-domain optical coherence tomography (OCT), swept-source OCT, swept-source OCT angiography and ultrasonography. RESULTS:The retinal lesions described shared similar appearance to RAHs but demonstrated unique features such as glistening granular appearance on fundus photographs with perivascular hyperreflectivity with OCT and OCT angiography. CONCLUSION/CONCLUSIONS:The lesions described herein appear to have unique characteristics that warrant a designation as a novel RAH variant. The name presumed retinal pericapillary astrocytic hamartoma is suggested.

Detection of Occult Arteriovenous Malformation With Annular Array Ultrasonography

Ledesma-Gil, Gerardo; Essilfie, Juliet; Freund, K Bailey; Yannuzzi, Lawrence A; Fisher, Yale L
Retinal vascular tortuosity may occur in a wide range of ocular disorders. When retinal vascular tortuosity involves both arteries and veins, and presents unilaterally and without hemorrhage, a diagnosis of Wyburn Mason syndrome (WMS) should be considered due to the potential morbidity and mortality associated with cerebral involvement. Magnetic resonance imaging (MRI) and MRI angiography (MRA) are important tools for identifying cerebral arteriovenous malformations (AVMs), but these imaging modalities have limited spatial resolution to detect very small vascular lesions. Annular array contact ocular ultrasound is a new imaging modality capable of detecting small intraorbital AVMs. [Ophthalmic Surg Lasers Imaging Retina. 2020;51:239-243.].

Multimodal Imaging of Punctate Outer Retinal Toxoplasmosis

Yannuzzi, Nicolas A; Gal-Or, Orly; Motulsky, Elie; Swaminathan, Swarup S; Cunningham, Emmett T; Davis, Janet L; Fisher, Yale; Gregori, Giovanni; Rosenfeld, Philip J; Freund, K Bailey
BACKGROUND AND OBJECTIVE/OBJECTIVE:To describe the multimodal imaging characteristics associated with punctate outer retinal toxoplasmosis (PORT). PATIENTS AND METHODS/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/CONCLUSIONS: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.

PRESUMED RETINAL PIGMENT EPITHELIUM TUMOR ORIGINATING FROM UNILATERAL RETINAL PIGMENT EPITHELIUM DYSGENESIS

Gal-Or, Orly; Finger, Paul T; Fisher, Yale L; Yannuzzi, Lawrence A; Freund, K Bailey
PURPOSE: To describe a patient with a presumed retinal pigment epithelium (RPE) tumor originating from unilateral RPE dysgenesis. METHODS: Case report. RESULTS: A 30-year-old woman with an unremarkable medical and ocular history was referred for an evaluation of progressive central metamorphopsia in her left eye. Visual acuity was 20/20 in her right eye and 20/25 in her left eye. Funduscopic examination of the left eye revealed an elevated mass within an area of unilateral RPE dysgenesis showing hyperpigmentation and hypopigmentation with scalloped margins. Fundus autofluorescence of the lesion showed a marginal pattern of hyperautofluorescence and hypoautofluorescence that was the inverse of the fluorescein angiography pattern. A well-circumscribed subretinal mass appeared to originate from the unilateral RPE dysgenesis lesion with surrounding subretinal fluid extending beneath the fovea. Ultrasonography showed medium-to-high reflectivity of the mass with no evidence of choroidal involvement. Optical coherence tomography showed a subretinal hyporeflective mass consistent with a tumor of RPE origin. The tumor appeared to invade the overlying retina where fluorescein angiography showed hyperfluorescent leakage and OCT angiography showed retinal vascular deformation. Indocyanine green angiography showed no evidence of choroidal neovascularization. Findings in the right fundus were normal. Over a 5-month follow-up, intravitreal anti-vascular endothelial growth factor therapy induced a resolution of subretinal exudation and modest reduction in tumor thickness. CONCLUSION: To the authors' knowledge, this is the first report of a presumed RPE tumor described as originating from unilateral RPE dysgenesis. Multimodal imaging was crucial for establishing the diagnosis and showing that the patient's visual symptoms were a product of the exudation produced by the tumor's invasion of the retina.

Panuveitis With Exudative Retinal Detachments After Vaccination Against Human Papilloma Virus

Dansingani, Kunal K; Suzuki, Mihoko; Naysan, Jonathan; Samson, C Michael; Spaide, Richard F; Fisher, Yale L
A 20-year-old white woman presented with bilateral acute visual loss (visual acuity: 20/60), panuveitis, and exudative retinal detachments 3 weeks after a second dose of quadrivalent human papillomavirus (HPV4) vaccine. She was treated with oral prednisolone for 6 weeks and responded rapidly. By week 4, vision had normalized and clinical signs resolved. Uveitis after HPV4 vaccination has been reported in two cases. Although the differential diagnosis includes Harada disease, temporal correlation with HPV4 and definitive response to a short course of treatment implicate the vaccine in this case. Vaccine-induced uveitis is rare and difficult to distinguish from coincidental autoimmune disease. [Ophthalmic Surg Lasers Imaging Retina. 2015;46:967-970.].
