Tessellation of the ocular fundus is commonly found at a mild stage in myopic eyes, and their locations vary among individuals. We conducted this study to determine the distribution of tessellation locations in a population study.
A cross-sectional, population-based study. Residents of Kumejima older than 40 years were studied. The subjects filled out a comprehensive questionnaire, had their body height (BH) measured, and had an ocular examination. The location of the tessellation was classified into 6 patterns. Correlations between each pattern and the axial length (AL), age, and BH were statistically determined.
Reliable measurements of the AL and fundus photographs of the right eyes were obtained from 1670 subjects. Nine hundred eleven eyes had no tessellation, 113 eyes had tessellation in the posterior pole, 118 eyes had tessellation in the macular area, 383 eyes had tessellation in the peripapillary region, 6 eyes had tessellation in the nasal region, and 239 eyes had tessellation in the inferior region. The AL of the "no tessellation" group was significantly shorter than that of the posterior pole and macular groups (P < 0.01). The individuals of the posterior pole and peripapillary groups were significantly older than in all other groups (P < 0.05) except for the nasal group. The individuals in the inferior tessellation group were significantly taller than those in the no tessellation, posterior pole, and peripapillary groups (P < 0.01).
The location distribution of the tessellation is important in correctly interpreting and predicting myopic changes.
在近视眼中，眼底部的镶嵌图案通常在轻度阶段出现，并且它们在个体之间的位置有所不同。我们进行这项研究是为了确定人群研究中镶嵌位置的分布。
这是一项横断面、基于人群的研究。研究对象为久米岛年龄在 40 岁以上的居民。受试者填写了一份综合问卷，测量了他们的身高（BH），并进行了眼部检查。将镶嵌位置分为 6 种模式。统计确定了每种模式与眼轴长度（AL）、年龄和 BH 之间的相关性。
从 1670 名受试者中获得了可靠的 AL 测量值和右眼眼底照片。911 只眼无镶嵌，113 只眼后极部有镶嵌，118 只眼黄斑区有镶嵌，383 只眼视盘周围区有镶嵌，6 只眼鼻侧有镶嵌，239 只眼下侧有镶嵌。“无镶嵌”组的 AL 明显短于后极部和黄斑部（P<0.01）。后极部和视盘周围部的个体明显比其他所有组（除了鼻侧组）都要年长（P<0.05）。下侧镶嵌组的个体明显比无镶嵌、后极部和视盘周围部的个体高（P<0.01）。
镶嵌的位置分布对于正确解释和预测近视变化很重要。
