Abstract:

Fundus tessellation has been defined as the visibility of large choroidal vessels at the posterior fundus pole outside of the peripapillary region. Factors on the increased visibility of the large choroidal vessels in eyes with a marked fundus tessellation may include an increased transparency of the retinal pigment epithelium, an reduced filling of the choriocapillaris, an increased pigmentation of the intrachoroidal regions between the large horoidal vessels. Thinner subfoveal choroidal thickness is strongly associated with higher degree of fundus tessellation. Observing fundus tessellation is useful for estimating choroidal thickness. Additionally, fundus tessellation is associated with diseases like high myopia, primary open angle glaucoma and age-related macular degeneration. Observing fundus tessellation is useful for diagnosis, differential diagnosis and exploring pathogenesis of these eye diseases. (Int Rev Ophthalmol,  2017,  41:   367-371)
