We report 2 peripapillary pit cases, in which the isolated visual field defects spatially correspond to the pit-related retinal nerve fiber layer and optical coherence tomography (OCT) angiography (OCTA) perfusion damage areas. A high myopic eye of a 39-year-old Japanese male patient, and a moderate myopic eye of a 47-years old Caucasian female patient were evaluated with OCT, OCTA, and visual field testing for peripapillary pits and spatially corresponding localized visual field defects. In the Japanese patient a temporal and in the Caucasian patient an inferotemporal peripapillary pit was confirmed, both spatially associated with a myopic peripapillary atrophy area. In both cases, the retinal nerve fibers herniated into the pit. En face OCT and OCTA revealed retinal nerve fiber bundle defects and reduced vessel density in the corresponding areas, both projecting to the pit. The visual field showed localized scotomas spatially corresponding to the nerve fiber bundle/OCTA defects in both patients. The visual field defect was a progressing (extending and deepening) paracentral scotoma in the Japanese patient, and a localized superior paracentral and superior arcuate scotoma in the Caucasian patient. Our cases show that peripapillary pits occurring in both Japanese and white European eyes can cause localized retinal nerve fiber bundle and OCTA damage and visual field defects of which some can worsen during the follow-up. To separate scotomas due to peripapillary pits and glaucoma is therefore of clinical importance and requires special attention from ophthalmologists.

Clinical experience and multiple prospective studies, such as the Collaborative Normal Tension Glaucoma Study and the Los Angeles Latino Eye Study, have demonstrated that the diagnosis of glaucoma is more complex than identifying elevated intraocular pressure. As a result, increased emphasis has been placed on measurements of the structural and functional abnormalities caused by glaucoma. The refinement and adoption of imaging technologies assist the clinician in the detection of glaucomatous damage and, increasingly, in identifying the progression of structural damage. Because visual field defects in glaucoma patients occur in patterns that correspond to the anatomy of the nerve fiber layer of the retina and its projections to the optic nerve, visual functional tests become a link between structural damage and functional vision loss. The identification of glaucomatous damage and management of glaucoma require appropriate, sequential measurements and interpretation of the visual field. Glaucomatous visual field defects usually are of the nerve fiber bundle type, corresponding to the anatomic arrangement of the retinal nerve fiber layer. It is helpful to consider the division of the nasal and temporal retina as the fovea, not the optic nerve head, because this is the location that determines the center of the visual field. The ganglion cell axon bundles that emanate from the nasal side of the retina generally approach the optic nerve head in a radial fashion. The majority of these fibers enter the nasal half of the optic disc, but fibers that represent the nasal half of the macula form the papillomacular bundle to enter the temporal-most aspect of the optic nerve. In contrast, the temporal retinal fibers, with respect to fixation, arc around the macula to enter the superotemporal and inferotemporal portions of the optic disc. The origin of these arcuate temporal retinal fibers strictly respects the horizontal retinal raphe, temporal to the fovea. As a consequence of this superior-inferior segregation of the temporal retinal fibers, lesions that affect the superotemporal and inferotemporal poles of the optic disc, such as glaucoma, tend to cause arcuateshaped visual field defects extending from the blind spot toward the nasal horizontal meridian.
