To appropriate execute analysis of a blood vessel included in data on an eye to be examined.SOLUTION: An ophthalmological analysis device for analyzing data on an eye to be examined including information on a blood vessel of the eye to be examined includes analysis processing means for analyzing the data on the eye to be examined and acquiring a measurement result on a blood vessel region including a blood capillary region, the means acquiring, as the measurement result, vascular density or vascular area on the eye to be examined including the blood capillary region and a large blood vessel region. When acquiring the vascular density or the vascular area as the measurement result, the analysis processing means measures the vascular density or the vascular area of the eye to be examined including the blood capillary region and the large blood vessel region without specifying the blood capillary region by using arithmetic processing constructed so as to lighten specific gravity to the measurement result by a large blood vessel with a blood vessel diameter larger than that of the blood capillary.SELECTED DRAWING: Figure 6 【課題】 被検眼データに含まれる血管解析を好適に行うことができる。【解決手段】 被検眼の血管情報を含む被検眼データを解析するための眼科解析装置であって、前記被検眼データを解析して毛細血管領域を含む血管領域に関する計測結果を取得する解析処理手段であって、毛細血管領域と大血管領域を含む被検眼の血管密度又は血管面積を前記計測結果として取得する解析処理手段を備え、前記解析処理手段は、前記血管密度又は血管面積を計測結果として取得する際、毛細血管よりも血管径の大きい大血管による前記計測結果への比重を軽減するように構築された演算処理を用いて、前記毛細血管領域を特定せず毛細血管領域と大血管領域を含めた被検眼の血管密度又は血管面積を計測することを特徴とする【選択図】 図６
