What Is High Myopia and Pathological Myopia?
High myopia, commonly known as severe short-sightedness, occurs when distant objects appear blurred because light focuses in front of the retina. It is often defined as a refractive error of -6.00 diopters or more, although definitions may vary.
Pathological myopia is different from ordinary high myopia. It involves structural changes caused by excessive elongation of the eyeball. These changes can affect the retina, macula, retinal pigment epithelium (RPE), choroid and sclera.
In some individuals, these changes lead to myopic macular degeneration, which can affect central vision and make everyday activities such as reading and recognising faces difficult.
At Sanjeevan Netralaya, Hyderabad, the supportive-care approach focuses on understanding the extent of retinal involvement, assessing remaining functional vision and setting realistic goals alongside appropriate ophthalmic care.
Common Symptoms of Pathological Myopia
Symptoms depend on the degree of retinal and macular involvement. Common warning signs include:
Progressive central blur: Difficulty seeing fine details or reading clearly.
Visual distortion: Straight lines may appear bent or wavy.
Reduced contrast: Difficulty distinguishing objects from their backgrounds.
Floaters or flashes: New floaters or flashes may indicate a retinal complication.
Sudden vision loss: May occur if complications such as myopic macular neovascularisation or retinal detachment develop.
Some people with high myopia may not experience noticeable symptoms from early pathological changes. Regular retinal examinations are therefore important.
What Causes Pathological Myopia?
Pathological myopia develops when excessive axial elongation causes structural changes within the eye. As the eyeball becomes longer, the retina and surrounding tissues may stretch and become thinner.
Possible complications include:
Myopic maculopathy: Degenerative changes affecting the central retina.
Chorioretinal atrophy: Thinning or loss of retinal and choroidal tissue.
Myopic macular neovascularisation (mMNV): Abnormal blood vessels developing beneath or within the retina.
Myopic traction maculopathy: Structural changes caused by traction on the retina.
Retinal tears and detachment: Serious complications that can threaten vision.
The type and severity of these changes differ between individuals. A detailed examination helps identify the specific condition rather than treating all cases of high myopia in the same way.
How Is Pathological Myopia Diagnosed?
A retinal specialist may recommend several examinations to assess the eye's structure and identify complications.
Refraction testing: Measures the degree of short-sightedness.
Dilated retinal examination: Helps identify retinal thinning, degeneration, tears or other abnormalities.
Optical Coherence Tomography (OCT): Examines the macula and identifies structural changes, fluid or traction.
Fundus photography: Documents the appearance of the retina and myopic changes.
Additional retinal imaging: May be recommended when myopic macular degeneration or abnormal blood vessel growth is suspected.
Regular monitoring is important because some complications can develop even when a person has been living with high myopia for years.
Conventional Treatment for Pathological Myopia
Treatment depends on the specific complication and the extent of retinal damage. High myopia itself cannot be reversed by retinal supportive care, and pathological changes require appropriate specialist management.
Treatment options may include:
Regular monitoring: Retinal examinations and OCT imaging help track structural changes.
Anti-VEGF injections: Commonly used to treat active myopic macular neovascularisation.
Vitrectomy or other retinal surgery: May be required for selected cases of tractional maculopathy or retinal detachment.
Retinal laser treatment: May be recommended for certain retinal tears or related complications.
Visual rehabilitation: Low-vision aids can help patients manage reduced central vision.
Treatment should be individualised according to the diagnosis. New flashes, floaters or sudden visual changes require prompt retinal assessment.
Ayurvedic Supportive Care at Sanjeevan Netralaya
Sanjeevan Netralaya offers an individualised Ayurvedic supportive-care approach for selected patients with retinal and optic-nerve-related visual disorders.
For high and pathological myopia, supportive care focuses on the functional vision that remains and the patient's overall wellbeing. The approach does not claim to reverse excessive axial elongation or correct the structural changes caused by pathological myopia.
Supportive-care goals may include:
Supporting remaining retinal and macular visual function where appropriate.
Addressing practical visual difficulties involving contrast, clarity and object recognition.
Considering relevant systemic factors such as diabetes, blood pressure, sleep, nutrition and general wellbeing when clinically appropriate.
Helping patients recognise warning symptoms and maintain regular retinal follow-up.
Setting realistic goals based on retinal structure, disease activity and remaining functional vision.
Important: Ayurvedic supportive care has not been established to shorten the eyeball, reduce minus power, reverse myopic macular degeneration or regenerate permanently damaged retinal tissue. It should not replace or delay anti-VEGF injections, retinal laser treatment or surgery when medically recommended. Herbal products should be discussed with the treating clinician because they may cause side effects or interact with prescribed medicines.
What Results Can Patients Expect?
The potential outcomes depend on the degree of myopia, the extent of retinal and macular changes, the presence of complications and the amount of functional vision remaining.
Practical supportive-care goals may include making better use of residual central vision, improving everyday visual strategies, using appropriate reading aids and adapting to reduced contrast or fine-detail vision.
Individual responses vary, and specific improvements cannot be guaranteed. Supportive care should not be represented as reversing established structural damage or restoring retinal tissue that has been permanently lost.
Important Safety Signs: When to Seek Immediate Eye Care
People with high or pathological myopia have an increased risk of retinal tears and retinal detachment.
Seek urgent eye assessment if you experience:
A sudden increase in floaters.
New flashes of light.
A dark curtain or shadow moving across your vision.
Sudden distortion or a new central dark spot.
Abrupt or unexplained vision loss.
These symptoms may indicate a sight-threatening retinal complication. Do not wait for a routine appointment if they occur.

Frequently Asked Questions
What is the difference between high myopia and pathological myopia?
High myopia refers to a high degree of short-sightedness, commonly around -6.00 diopters or more. Pathological myopia involves structural changes in the eye due to excessive axial elongation, which may affect the retina and other structures.
Can pathological myopia cause blindness?
Severe complications such as retinal detachment, myopic macular neovascularisation and advanced macular degeneration can cause significant and sometimes permanent vision loss. Regular retinal monitoring and timely treatment are important.
Can Ayurveda reduce minus power or shorten the eyeball?
There is no established evidence that Ayurvedic care can reduce the axial length of the eyeball or reverse high myopia. Supportive care should not be presented as a substitute for appropriate eye treatment.
What is myopic macular neovascularisation?
It is the growth of abnormal blood vessels beneath or within the retina in some people with pathological myopia. It can cause sudden central distortion or blurred vision and is commonly treated with anti-VEGF injections.
How often should people with high myopia get their retina checked?
The frequency depends on the degree of myopia, retinal findings and individual risk factors. A retinal specialist can recommend an
appropriate follow-up schedule.
