Progressive Deformation of the Optic Nerve Head and Peripapillary Structures by Graded Horizontal Duction
Purpose We investigated the effect of graded range of horizontal duction on the shape of the peripapillary Bruch's membrane (ppBM) and optic nerve head (ONH). Methods In 50 eyes of 25 normal subjects, the ONH and peripapillary retina were imaged by optical coherence tomography (OCT) in central gaze and incremental angles of add- and abduction. Displacements of the Bruch's membrane opening (BM...
متن کاملOptical coherence tomography angiography of the peripapillary retina and optic nerve head in dominant optic atrophy.
Peripapillar and nerve head vessel density (VD) was measured in 10 patients affected by Dominant optic atrophy (DOA) using optical coherence tomography angiography (OCT-A) and compared to the measurements of 15 age- and gender-matched controls. DOA patients showed VD reduction, mostly in the temporal and inferotemporal peripapillary sectors, according to the preferential involvement of the papi...
متن کاملDeformation of the rodent optic nerve head and peripapillary structures during acute intraocular pressure elevation.
PURPOSE. To evaluate the effect of acutely elevated intraocular pressure (IOP) on retinal thickness and optic nerve head (ONH) structure in the rat eye by spectral domain-optical coherence tomography (SD-OCT). METHODS. Fourteen adult male Brown-Norway rats were studied under anesthesia (ketamine/xylazine/acepromazine, 55:5:1 mg/kg intramuscularly). Both eyes were imaged by SD-OCT on two baselin...
متن کاملMeasuring Deformation in the Mouse Optic Nerve Head and Peripapillary Sclera
Purpose To develop an ex vivo explant system using multiphoton microscopy and digital volume correlation to measure the full-field deformation response to intraocular pressure (IOP) change in the peripapillary sclera (PPS) and in the optic nerve head (ONH) astrocytic structure. Methods Green fluorescent protein (GFP)-glutamate transporter-GLT1 (GLT1/GFP) mouse eyes were explanted and imaged w...
متن کاملColoboma of optic nerve with overlay of peripapillary retina.
An eye that had the clinical appearance of a tumour of the nerve head was found on histological examination to have a congenitally large scleral canal with secondary buckling of the overlying retina.
