Take myopia seriously: greater severity is associated with more retinal, macular, and glaucoma complications later
Myopia does not simply go away or reverse; it is more than needing glasses. Compared with no myopia, a review found about 14 times the odds of myopic macular degeneration with low myopia, 73 times with moderate myopia, and 845 times with high myopia. Retinal detachment odds were about three times as high with low myopia and 13 times as high at −6 diopters or stronger. These are study associations, not an individual forecast. Earlier onset and faster progression can mean greater future risk.
What it takes
What you may gain
A systematic review and meta-analysis of studies available through June 2019 separated low myopia, −0.5 to −3.00 D; moderate, −3.00 to −6.00 D; and high, at or beyond −6.00 D in the negative direction. Compared with no myopia, odds ratios for myopic macular degeneration were 13.57, 95% CI 6.18–29.79; 72.74, 33.18–159.48; and 845.08, 230.05–3104.34, respectively. For retinal detachment they were 3.15, 1.92–5.17; 8.74, 7.28–10.50; and 12.62, 6.65–23.94. For posterior subcapsular cataract they were 1.56, 1.32–1.84; 2.55, 1.98–3.28; and 4.55, 2.66–7.75. Open-angle glaucoma OR was 1.59, 1.33–1.91, for low myopia and 2.92, 1.89–4.52, for moderate and high myopia combined. Visual impairment after age 60 had ORs 1.71, 1.07–2.74; 5.54, 3.12–9.85; and 87.63, 34.50–222.58. China's official guidance likewise identifies higher rates of cataract, open-angle glaucoma, myopic maculopathy, retinal detachment, and myopic optic neuropathy with high myopia and describes myopia as preventable and controllable but not reversible.
Context & considerations
These are observational odds ratios, not direct individual risk predictions. Some estimates are extremely large with wide intervals—for high-myopia macular degeneration, roughly 230–3104—so read them as a scale of association rather than precise multipliers. Many complications appear in middle or older age. Myopia itself does not necessarily constitute disability; most people achieve normal corrected vision. It still warrants prevention, progression management, and follow-up beyond buying glasses. See entry 12 for assessment and entry 9 for misleading cure claims.
