Abstract:
Objective To observe the types of posterior sclera shape (PSS) and macular shape (MS) in high myopia (HM) and its distributions in the pure HM and pathologic myopia (PM).Methods Together 90 patients with high myopia (163 eyes) in the Third Affiliated Hospital of Nanchang University were included in this study.The medical records from deep range imaging optical coherent tomography (DRIOCT) Atlantis and fundus photography examination were used to analyze the types and distributions of PSS and MS.Then all eyes were grouped into the pure HM group and MP group according to META-PM classification standard for comparing and analyzing the types and distributions of PSS and MS.Results Of all 90 patients (163 eyes),The type Ⅰ,Ⅱ,Ⅲ,ⅨX and Ⅶ PSS was in 44 eyes (27.0％),85 eyes (52.1％),15 eyes (9.2％),15 eyes (9.2％),4 eyes (2.5％),respectively.The type Ⅰ,Ⅱ,Ⅲ,Ⅳ horizontal MS was in 31 eyes (20.3％),23 eyes (15.0％),87 eyes (56.9％),12 eyes (7.8％),respectively.The type Ⅰ,Ⅲ,Ⅳ vertical MS was in 104 eyes (69.8％),28 eyes (18.8％) and 17 eyes (11.4％),respectively.As for horizontal MS combined with vertical MS,type Ⅲ + Ⅰ was in 62 eyes (38.8％),type Ⅰ + Ⅰ in 26 eyes (16.3％),type Ⅲ + Ⅲ in 22 eyes (13.8％),type Ⅱ + Ⅰ in 20 eyes (12.5％),and type Ⅳ + Ⅳ in 10 eyes(6.3％);the others 7 types were in 20 eyes (12.5％).There were statistically significant differences in distribution of PPS and horizontal MS between the pure HM and MP group (x2 =12.67,47.60;P ＜ 0.01).Conclusion Patients with pure high myopia has mainly type Ⅰ,Ⅱ PPS,and type Ⅲ horizontal MS together with type Ⅰ vertical MS plus type Ⅲ + Ⅰ horizontal combined with vertical MS,while type]X PSS and type Ⅳ horizontal MS were commonly seen in PM.
