AO: Tessellated background, more marked in the infero-nasal quadrants due to the possible presence of an elongated globe towards the infero-nasal or an infero-nasal staphyloma.

Increased visibility of the large choroidal vessels as a result of pigment loss and attenuation of the retinal pigment epithelium secondary to axial elongation, tissue stretching, and retinal and choroidal thinning. It is one of the earliest and preliminary signs of high myopia and corresponds to category 1 of atrophic myopic maculopathy in the ATN classification. The tessellated background alone has not been associated with loss of visual acuity.
