Eye diseases may affect visual quality, the ocular surface, retina, optic nerve, and ocular blood supply. Ozone therapy is being investigated as a complementary approach in selected eye-related contexts, particularly regarding oxidative stress, microcirculation, tissue oxygenation, and inflammation balance.

Key Points
- Diagnosis and treatment of eye diseases must be performed by an ophthalmologist.
- Ozone therapy does not replace standard ophthalmological care; it may only be evaluated as a complementary approach in selected cases.
- Ozone gas must not be applied directly to the eye or inhaled.
What Are Eye Diseases?
Eye diseases include conditions affecting the cornea, conjunctiva, lens, retina, macula, optic nerve, and ocular blood vessels. Dry eye, conjunctivitis, keratitis, corneal surface problems, age-related macular degeneration, diabetic retinopathy, glaucoma, and retinal vascular disorders may be considered within this broad group.
Because eye tissues are highly sensitive to light, oxygen, circulation, and inflammation, oxidative stress and microvascular changes may play a role in some eye-related conditions. For this reason, redox balance, tissue oxygenation, and microcirculation are among the areas of research in ophthalmology.
Early diagnosis, regular follow-up, and appropriate ophthalmological treatment are essential to reduce the risk of vision loss.
Eye Conditions Being Investigated
Research on ozone-related approaches in eye health varies according to the affected tissue and the underlying mechanism.
Ocular surface conditions: Studies have evaluated ozone-based ophthalmic preparations in selected conditions involving the ocular surface, such as conjunctivitis, keratoconjunctivitis, and corneal epithelial problems.
Retinal and macular conditions: In dry age-related macular degeneration and selected retinal disorders, systemic ozone applications have been investigated for their potential effects on microcirculation and retinal metabolism.
Oxidative stress-related conditions: Because oxidative stress may affect the retina, cornea, and optic nerve, ozone’s possible role in redox balance is being explored.
Chronic inflammatory conditions: In some chronic ocular surface or inflammation-related conditions, supportive approaches are being studied.
Symptoms
Symptoms of eye diseases may vary depending on the condition and affected tissue.
- Blurred vision
- Redness of the eye
- Burning, stinging, or dryness
- Light sensitivity
- Eye pain
- Discharge or excessive tearing
- Floaters or flashes of light
- Narrowing of the visual field
- Central vision distortion or wavy vision
When to seek care: Sudden vision loss, severe eye pain, flashes of light, a curtain-like shadow over vision, trauma, chemical exposure, intense redness, or signs of infection require urgent ophthalmological evaluation.
Causes and Risk Factors
The causes of eye diseases vary depending on the condition. Genetic predisposition, aging, diabetes, hypertension, infection, trauma, intense screen exposure, contact lens use, smoking, ultraviolet exposure, and chronic inflammation may affect eye health.
Common risk factors include:
- Advanced age
- Diabetes and hypertension
- Smoking
- Family history of eye disease
- Long-term UV exposure
- Poor contact lens hygiene
- Chronic infection or inflammation
- Eye trauma
- Immune system disorders
Depending on the suspected condition, ophthalmological evaluation may include eye examination, retinal examination, OCT, visual field testing, eye pressure measurement, corneal assessment, and laboratory tests when needed.
The Role of Ozone Therapy
Ozone therapy is the controlled medical use of a mixture of pure oxygen and ozone gas. In eye-related conditions, ozone is being investigated mainly for its potential effects on oxidative stress balance, microcirculation, tissue oxygenation, and inflammatory response modulation.
In retinal and macular conditions, systemic ozone applications have been studied for possible effects on blood flow, oxygen utilization, and antioxidant defense mechanisms. In ocular surface conditions, ophthalmic ozone-based preparations have been investigated for their potential antimicrobial and tissue-supportive properties.
However, ozone therapy does not replace standard ophthalmological treatment. Conditions such as retinal disease, glaucoma, infection, corneal disease, or sudden vision changes must be diagnosed and managed by an ophthalmologist.

Application Methods
Ozone-related applications in eye conditions must be planned according to the type of disease, affected tissue, patient history, and ophthalmologist evaluation.
Major autohemotherapy: May be considered as systemic support in selected protocols under physician supervision.
Rectal ozone application: May be evaluated in selected systemic supportive protocols when considered appropriate by a physician.
Topical ophthalmic ozone-based preparations: Only products specifically intended for ophthalmic use and recommended by a physician should be considered.
Supportive protocols: Management of diabetes, hypertension, oxidative stress, chronic inflammation, and lifestyle-related factors may be considered alongside standard ophthalmological care.
Note: Ozone gas must not be applied directly to the eye, inhaled, or used in an uncontrolled manner. Any eye drop, solution, topical preparation, or systemic ozone application should be evaluated by a physician.
Potential Supportive Effects
-
May support oxidative stress and antioxidant defense balance.
-
May contribute to microcirculation support in selected eye-related contexts.
-
May help support tissue oxygenation.
-
May be evaluated in selected ocular surface conditions when ophthalmic products are appropriate.
-
May be considered as part of a broader supportive care plan in chronic eye-related conditions.
These potential effects may vary depending on the disease type, degree of tissue damage, presence of diabetes or hypertension, and application method.
Scientific Evidence
Studies on ozone therapy in eye diseases are limited but include different research areas. In dry age-related macular degeneration, major ozonated autohemotherapy has been evaluated in clinical research for its possible effects on selected clinical parameters.
In ocular surface conditions, ozone-based eye drops or ozonated preparations have been studied for biological activity on ocular epithelial cells and selected pathogens. Some publications discuss their potential role in conjunctivitis, keratoconjunctivitis, and corneal surface problems.
However, uncontrolled atmospheric ozone exposure may be harmful to the ocular surface and may contribute to irritation or inflammation. Therefore, controlled medical or ophthalmic ozone-based applications must be clearly distinguished from environmental ozone exposure.
More high-quality, controlled, and long-term clinical studies are needed before ozone therapy can be considered a standard approach in eye diseases.
