Evaluation of crowded optic nerve head and small scleral canal in intrapapillary hemorrhage with adjacent peripapillary subretinal hemorrhage

Abstract

Patients with IHAPSH have smaller optic discs and scleral canals than control subjects, with a higher level of nerve fiber crowding.

The Connective Tissue Components of Optic Nerve Head Cupping in Monkey Experimental Glaucoma Part 1: Global Change

“…10,12,47 The influence of anterior scleral canal opening size and shape on connective tissue change in glaucoma will need to be assessed within prospective longitudinal studies in which this aspect of ONH geometry is assessed using OCT or other vivo techniques. 26,[48][49][50] Finally, while laminar thickness change does not directly contribute to clinical phenotype, a large effort is underway to measure laminar thickness using OCT. 51 Our cross-sectional findings suggest that the lamina initially deforms and thickens in response to chronic IOP elevation in most monkey eyes. If EG eye IOP is left untreated, the lamina eventually thins from this thickened state which, in the most deformed eyes, leaves it thinner than the lamina of its contralateral control eye.…”

Spontaneous intrapapillary hemorrhage with adjacent peripapillary subretinal hemorrhage in adolescents

“…First, the coexistence of a crowded, tilted disc, [2,5,6,8] disc edema, [2,5] and high myopia [9,10] has been observed in previously published reports. Our series show similar results as crowded and edematous optic nerve head was found on fundoscopic examination and was further supported by similar findings on OCT in the cases this was performed in.…”

“…[1] These cases were distinct due to the significant bleeding within the optic disc that extends into the peripapillary subretinal space; in some cases, vitreous hemorrhage occurs too. It has been described more frequently in patients with myopia, small, mildly dysplastic, tilted optic discs [2][3][4][5][6][7][8] and in the young Asian population. [3][4][5]8] Despite the alarming appearance, a good visual prognosis has been documented where there is spontaneous resolution without intervention.…”

“…[3][4][5]8] Despite the alarming appearance, a good visual prognosis has been documented where there is spontaneous resolution without intervention. [1][2][3][4][5][6][7][8] The cause of this condition is unknown. Vitreous traction on the optic disc during posterior vitreous detachment has been proposed as one possible cause for IHAPSH.…”
