    Abstract:

    AIM: To determine the prevalence and characteristics of peripheral myopic retinopathy among a sample of Guangzhou office workers. METHODS: A cross-sectional study of Guangzhou Chinese office works in different departments and units of the Guangzhou Power Supply Bureau, China, in 2016. Myopic retinopathy was recorded and analyzed with a scanning laser ophthalmoscope and by slit-lamp microscopy combined with a three-mirror contact lens. RESULTS: In total, 1910 eyes of 955 subjects (508 females and 447 males) aged 21-59y were included; 69.6% of these eyes were myopic. The myopia group had a younger age and worse uncorrected visual acuity (UCVA) and best-corrected visual acuity (BCVA) when compared with hyperopia and emmetropia groups (P<0.001). The axial length (AL) was significantly longer, the spherical equivalent (SE) was more serious, and the optic nerve crescent was significantly larger in subjects with myopia than with hyperopia and emmetropia. Subjects with myopia, and especially high myopia, had the highest frequency of myopic retinal 18 changes (49.4%, P<0.001) [white-without-pressure (43.8%, P<0.001), lattice degeneration (4.5%, P=0.044)] among the three groups. Logistic regression confirmed that any myopia (OR: 3.41, P<0.001) [mild myopia (OR: 1.93, P=0.001), moderate myopia (OR:3.64, P<0.001), and high myopia (OR:10.58, P<0.001)], a greater AL (OR: 1.55, P<0.001) and a much higher SE (OR: 0.77, P<0.001) increased the risk for peripheral retinal changes. CONCLUSION: Myopia-related retinal changes are positively associated with greater AL, higher SE, and myopia.
