強度近視に合併した新生血管を伴う黄斑出血56眼50症例を老人性円板状黄斑変性症121眼100症例と対比して,性別,年齢,屈折,眼軸長について検索した。老人性黄斑変性については,性と年齢が等しい121眼100症例を対象群として比較した。
強度近視群では3.17の比率で女性に多かった。老人性円板状黄斑変性症は,1.70の比で男性に多かった。強度近視の屈折は−7.0Dから−23.5Dの間であり,平均−14.54±3.78Dであった。老人性円板状黄斑変性症の屈折は+4.75Dから−2.25Dの間であり,平均+1.06±1.25Dであった。この2群の間に屈折異常の重複はなかった。対象群での屈折は+0.05±1.91Dであり,老人性円板状黄斑変性症でのそれと有意の差があった(P<0.05)。眼軸長は,強度近視群で29.14±1.47mm,老人性黄斑変性群で22.53±0.88mmであり,両者間に有意の兼があった。
We evaluated the distribution of sex, age, state of refraction and axial length in 56 eyes of 50 patients with macular neovascularization with hemorrhage and in 121 eyes of 100 patients with senile disciform macular degeneration. The findings were compared with those in 121 eyes of 100 cases matched for age and sex.
In the high myopia group, women were more numerous than men at the ratio of 3.17. In senile macular degeneration, men were more numerous than women at the ratio of 1.70. The state of refrac-tion in high myopia group ranged from -7.0D to-23.5D, average -14.5±3.78D. That in senile macular degeneration raged from +4.75D to -2. 25D, average +1.06±1.25D. The range in refractive power did not overlap in the two groups. The refraction in the control group averaged +0.05±1. 91D. This value was statistically significant from that in senile disciform macular degeneration (p<0.05).
The axial length in high myopia averaged 29.14± 1.47 mm and that in senile disciform macular degen-eration averaged 22.53±0.88 mm. These values were statistically significant.
