Abstract:
Objective To analyze the blindness and visual impairment attributed to myopic maculopathy in highly myopic patients based on the ATN classification system,as well as associated risk factors.Methods In this retrospective case-control study,clinical data of 642 adult patients(642 eyes)with high myopia admitted to the Department of Fundus Disease,Chengdu Bright Eye Hospital from January 2022 to September 2023 were collected and analyzed.Comprehensive ophthalmic examinations were conducted for all patients.Myopic maculopathy in patients with high myopia was diagnosed and graded according to the ATN classification system.The patients were divided into the blindness or visual impairment group and the non or mild visual impairment group based on the WHO diagnostic criteria for blindness and visual impair-ment.Multivariate Logistic regression was utilized to analyze the risk factors for blindness or visual impairment in patients with high myopia.Results Among the 642 eyes,myopic maculopathy was identified in 355 eyes(55.30%).Of these,there were 330 eyes(51.40%)with myopic atrophy maculopathy(A2 and above),137 eyes(21.34%)with myopic trac-tion maculopathy,and 82 eyes(12.77%)with myopic neovascular maculopathy.The percentages of blindness and visual impairment were 2.02%(95%CI:0.93%-3.11%)and 8.41%(95%CI:6.26%-10.56%),respectively.Multivariate Lo-gistic regression analysis showed that older age,longer axial length and higher grade of myopic atrophy maculopathy were independent risk factors for blindness or visual impairment in patients with high myopia(all P<0.05).Conclusion The ATN classification system can comprehensively reflect the disease severity and visual impairment of patients with myopic maculopathy.Older age,longer axial length and higher grade of myopic atrophy maculopathy are independent risk factors for blindness or visual impairment in patients with high myopia.
