High myopia is no longer just a refractive problem—it is increasingly recognised as a progressive eye disease, especially when it appears early in life or runs in families. In India, paediatric and adult ophthalmology centres are reporting a consistent rise in high myopia (defined as –6.00 D or higher), driven by genetics, lifestyle, and rapid urbanisation. Studies estimate that by 2030, nearly 30–35% of urban Indian teenagers may be myopic, with a significant proportion at risk of developing high myopia.
But what concerns specialists the most is the family pattern. When one or both parents are highly myopic, the child has a 3–6 times higher risk of developing high myopia. And unlike simple myopia, high myopia can lead to severe retinal complications—some of which can threaten vision if not detected early.
Why Genetics Play Such a Big Role
Indian paediatric ophthalmologists frequently emphasise that while lifestyle (screen time, near work, lack of outdoor exposure) accelerates myopia progression, genetic susceptibility determines who progresses faster. If high myopia runs in families, the child’s eyeball is more likely to elongate beyond normal limits, causing stretching and thinning of the retina.
This thinning is what makes the retina vulnerable—and why a retinal specialist becomes crucial.
Retinal Risks Associated with High Myopia
High myopia is often considered a “silent risk” because the refractive error can be corrected with glasses, giving a false sense of security. However, the underlying retinal weakness remains.
Common complications Indian retinal specialists watch for:
1. Lattice Degeneration
Seen frequently in high myopes, these weak patches can predispose the eye to retinal holes or tears.
2. Retinal Detachment
High myopes have a 5–10 times higher risk of retinal detachment. Sudden flashes, floaters or shadows in vision need immediate evaluation.
3. Myopic Maculopathy
Progressive degeneration of the central retina (macula) can lead to central vision loss, especially in adults over 40.
4. Choroidal Neovascularisation (CNVM)
Abnormal new blood vessels can form under the retina, causing rapid vision loss. This requires specialised retinal injections and OCT monitoring.
5. Early-onset Glaucoma or Cataract
High myopia is associated with anatomical changes that increase the risk of glaucoma and early lens changes.
Why a Retinal Specialist Is Essential
Most routine eye exams focus on refractive correction. But for high myopia—especially with a family history—the evaluation must go deeper. Across major Indian institutions, the standard recommendation includes:
- Dilated retinal examination (every 6–12 months)
- OCT (Optical Coherence Tomography) for macular thinning
- Wide-field fundus imaging to detect peripheral lattice or tears
- Prophylactic laser treatment for weak retinal areas
- Monitoring for myopic CNVM, especially in adults
A retinal specialist is trained to identify subtle structural changes long before symptoms appear—critical for preventing serious complications.
What Families Should Do
Indian paediatric eye clinics advise the following for families with hereditary myopia:
- Screen children as early as age 3–4
- Encourage at least 2 hours of outdoor play daily
- Follow myopia control therapies such as low-dose atropine, orthokeratology or special myopia-control lenses
- Annual or biannual retinal exams for all high-myopic family members
- Seek urgent care for flashes, floaters, sudden blurring or vision shadows
When high myopia runs in families, the focus should shift from “power of glasses” to health of the retina. With India seeing rising numbers of young high-myopes, timely retinal specialist involvement is not optional—it is essential. Early detection can prevent lifelong complications and preserve vision for decades.
