Provided is a myopia progress diagnostic device, which is possible to easily diagnose the progress of onset myopia for juveniles and adults, predict whether there will be progressive onset myopia, and prescribe contact lenses which fit their eyes. As denoted in Fig. 1, the device comprises: a light projection unit (13) which projects a measurement light upon the retina in a direction that forms an angle [theta] with an optical focal line joining the approximate center of the pupil of a subject eyeball (2) with the macula a photo detector unit (14) which receives light that is reflected from the retina and acquires optical data (D17) in the peripheral visual field of the fundus oculi and a data analysis unit (20) which analyzes the optical data (D17), derives PSF characteristics of the location of the focal point of the measurement light in the angle [theta] and of the locations fore and aft of the said focal point, and, on the basis of the PSF characteristics, assesses whether a hypermetropic aft focal point is present in the peripheral visual field of the fundus oculi of the subject eyeball (2). It would be possible to measure a corrective prescription lens strength necessary to alleviate myopia from the degree of hypermetropy obtained with this measurement system.能夠容易診斷兒童及成人的近視加深,並且能夠在預測兒童等的近視加深有無的同時並下達適合兒童等的隱形眼鏡的處方的近視加深用診斷裝置,如第1圖所示,具備光照射部13,朝向相對於被檢測眼球2的瞳孔的略中心與黃斑部連線的眼軸線成角度θ方向的網膜照射測量光;光檢測部14,接收網膜反射的光並取得在眼底的周邊視野的光學資料D17;以及資料解析裝置20,解析光學資料D17求出角度θ下的測量光的焦點位置及該焦點的前後位置的PSF特性,根據該PSF特性判別被檢測眼球2的眼底的周邊視野是否有遠視性的後焦點存在。從本測量系統中獲得的遠視度數能夠測量出抑制近視所必要的矯正度數。10‧‧‧光學資料取得部13‧‧‧光照射部14‧‧‧光檢測部17‧‧‧資料輸入輸出部20‧‧‧資料解析裝置(資料解析部)21‧‧‧鍵盤22‧‧‧滑鼠23‧‧‧控制部24‧‧‧顯示部31‧‧‧演算部32‧‧‧判別部33‧‧‧資料輸入輸出部34‧‧‧記憶體部D17‧‧‧光學資料D21‧‧‧鍵盤資料D22‧‧‧操作資料D24‧‧‧顯示資料D33‧‧‧控制資料DIN‧‧‧眼底形狀資料Ds‧‧‧S曲線資料
