Abstract

Purpose: There are several different types of staphyroma in highly myopic eyes. Tessellation is one of the characteristic myopic changes in pigmented fundi and some tessellation fundi may progress into the staphyroma. Therefore we hypothesized there are several types of tessellation in young healthy eyes. The purpose of this study was to investigate the location of the tessellation in young healthy eyes and to compare the myopic changes among the type of tessellation.

Methods: A prospective observational cross-sectional study comprised 126 right eyes of 126 healthy young Japanese participants. All participants (mean age 26.0 ± 4.1) underwent comprehensive ophthalmologic examination, including measurement of axial length and color fundus photography. Optic disc tilt was quantified using sine curve approach of the Topcon 3D OCT-1000 Mark II RNFL 3.4 mm circle scan images. We classified ocular fundus into the following seven categories, such as no tessellation (NO), temporal (T), infra-temporal (IT), inferior (I), nasal (N), peripapillary (PP), whole (W), unclassified (U) group, based on the location of the obvious tessellation. The Steel-Dwass multiple comparison test was used to analyze the significant difference of axial length, optic disc plus conus area, optic disc tilt among the groups.

Results: Forty-four eyes were categorized as NO group, 12 eyes as T group, 21 eyes as IT group, 9 eyes as I group, 8 eyes as N group, 15 eyes as PP group, 11 eyes as W group, and 6 eyes as U group. In the multiple comparison analysis, for axial length, there was significantly difference between NO and either IT or W group. For optic disc plus conus area, there was significantly difference between NO and I, IT or PP group. For optic disc tilt, there was significantly difference between NO and IT group (p<0.05).

Conclusions: There was an individual variation in the location of the tessellation in young healthy eyes. Comparing the NO group, the IT group had longer axial length, larger optic disc plus conus area, and larger optic disc tilt.
