“…On one hand, the funduscopic distortion induced by ODD was measured as ‘Relative Disc Index.’ Relative Disc Index was calculated as the proportion between the longest diameter of the funduscopic disc margin and the fovea-to-disc diameter ( Fig 1 , a / b ). Unlike type 2 ODD, the disc margin of type 1 ODD was not clearly discernible, due to the halo, as previously reported [ 15 ]. Halo was defined as a blurring of the optic disc margin on the fundus photographs [ 15 ].…”

“…Unlike type 2 ODD, the disc margin of type 1 ODD was not clearly discernible, due to the halo, as previously reported [ 15 ]. Halo was defined as a blurring of the optic disc margin on the fundus photographs [ 15 ]. In these cases, we measured the longest diameter of the halo ( Fig 1A ), since we wanted to measure the distortion induced by ODD, and not the actual disc size on the funduscopic plane.…”

PurposeTo investigate the prevalence and risk factors for visual field defect in patients with optic disc drusen (ODD).MethodsWe assessed the visual field status of patients with ODD whose diagnosis were confirmed by spectral-domain optical coherence tomography (SD-OCT). Visual field defects were classified as normal, enlarged blind spot, or other defects. ODD were classified into either type 1 (without hyperreflective border and heterogenic internal reflectance) or type 2 (with hyperreflective border and lower internal reflectance). The prevalence and risk factors for each visual field defect was analyzed using logistic regression analysis and classification and regression tree (CART) modeling.ResultsOf the 40 eyes with ODD, 33 (83%) eyes were categorized as type 1 and 7 (17%) eyes were categorized as type 2 ODD. Regarding the visual field defects, 19 (48%) eyes showed normal visual field, 11 (28%) eyes showed enlarged blind spot, and 9 (24%) eyes showed other defects. The latter was more frequent in type 2 ODD (P = 0.001). Logistic regression analysis revealed that the factor associated with other defects was the thinning of the average retinal nerve fiber layer (RNFL) (per 10 μm decrease, OR = 3.436, P = 0.004), and the factor associated with enlarged blind spot was the height of ODD (per 100 μm increase, OR = 3.956, P = 0.023). CART modeling revealed that the average RNFL thickness lesser than 85.5 μm, and then the ODD height larger than 348 μm were the best split-up factors for predicting the type of visual field defects.ConclusionsIn this study, one-quarter of ODD patients showed abnormal visual field defect other than enlarged blind spot. These other visual field defects appeared to be associated with the axonal loss in the eyes with type 2 ODD.

ZusammenfassungDrusenpapillen sind mit etwa 2% Prävalenz eine sehr häufige Papillenanomalie. Der Pathomechanismus ihrer Entstehung ist unklar. Wenn das ophthalmoskopische Bild nicht eindeutig ist, kann bei unregelmäßig dominantem Erbgang die Untersuchung von Verwandten weiterhelfen. Kalkeinlagerungen sind häufig und lassen sich sonografisch darstellen. Drusen können auch mittels optischer Kohärenztomografie (OCT) im Schnittbild und in der Autofluoreszenz nachgewiesen werden. Der genauen Funduskopie und Befunddokumentation sowie Verlaufskontrolle kommt eine große Bedeutung zu. Es gibt keine Therapie für Drusenpapillen, der Augeninnendruck sollte regelmäßig kontrolliert werden, da sich ein Glaukom nicht am Papillenbefund erkennen lässt. Das Risiko für die anteriore ischämische Optikusneuropathie ist erhöht.

“…Using EDI OCT, a new feature of the swollen optic nerve has been identified and termed peripapillary hyperreflective ovoid mass-like structure (PHOMS). Although the term PHOMS was codified as a feature seen in association with ONHD by the Optic Disc Drusen Studies Consortium [1,5,[7][8][9], subsequent studies have shown that PHOMS may be a feature of papilledema, papillitis, myopia, and anomalous optic nerves [10][11][12].…”

Purpose of reviewThe purpose of this review is to provide an overview of the ophthalmic findings associated with peripapillary hyperreflective ovoid mass-like structures (PHOMS) in both adult and pediatric patients.Recent findingsPHOMS have recently been identified in a number of different ophthalmic disease entities ranging from nonpathologic to pathologic, including but not limited to anatomic abnormalities (tilting in myopia), optic nerve head drusen, optic disc edema from inflammation (optic neuritis, white dot syndromes), vascular insults (ischemic optic neuropathy, retinal vascular occlusion), and papilledema. The mechanism underlying the formation of PHOMS has not been fully elucidated although it has been hypothesized that PHOMS occur secondary to axoplasmic stasis from crowding at the optic nerve head.SummaryAlthough the clinical significance of the presence of PHOMS remains unclear, PHOMS are associated with several disease processes. Understanding the mechanism behind their formation and their impact on optic nerve head structure and visual function may be relevant in patients with optic nerve head pathology. The presence of PHOMS may also correlate with disease severity and duration. Future studies to evaluate whether the formation of PHOMS may be useful as an early indicator of disease or a prognostic tool are warranted.

Abstract: In the patients with blurred disc margin, the presence of a halo strongly suggested underlying ODD rather than ODE.
