The eye is a wonderful organ. 

It is extremely complex, as can be seen from the diagram on the left, with a considerable number of parts that could go wrong. 

The diagram does not show every part, even though it is quite comprehensive.  It does not show the eyelid [the conjunctiva lines the inside of the eyelids]; lacrimal system [tears and watering system]; or the eyelashes and eyebrows.  

The medical profession call these the ‘Accessory visual structures’,  a term often used to mean the eyebrow, eyelids with lashes, and lacrimal apparatus.  A number of things can go wrong even with the eyelashes.

Ours is not a medical site, as such this section does not include every disease of the eye [of which there are literally hundreds and hundreds]. 

But one of its aims is to help people who have spiritual experiences that are unwanted, find out why they had them.  As such we have limited the description of eye diseases to those that have caused unwanted experiences.

It is worth adding that so beautifully designed is the eye, so precise and carefully balanced that even Charles Darwin was forced to admit that:

"To suppose that the eye, with all its inimitable contrivances for adjusting the focus to different distances, for admitting different amounts of light, and for the correction of spherical and chromatic aberration, could have been formed by natural selection, seems, I freely confess, absurd in the highest possible degree."

And it doesn't matter what he said next, because that is praise enough for the Creator.

Eye diseases


We have a separate section for the following diseases, where all the observations are also grouped under these headings

  • Blindness, macular degeneration and other sight impairment - this section is extremely comprehensive and covers a range of causes as well as types of sight impairment, thus if your disease is not described here this section may be of help
  • Cataracts - A cataract is a clouding of the lens in the eye leading to a decrease in vision. It can affect one or both eyes. Because it is so prevalent and also treatable, we have given it its own section.  Cataracts are the cause of  33% of visual impairment worldwide.
  • Glaucoma -Glaucoma is a group of eye diseases which result in damage to the optic nerve and vision loss. A major risk factor is increased pressure in the eye.  It along with the drugs used to treat this disease have their own section

 What other illnesses and diseases have caused spiritual experiences?

In other sections we have separated the causes from the diseases, but here we have decided it may be helpful to include the causes with the diseases, so that you can see the pattern emerging.



Retinitis is inflammation of the retina in the eye.  It can lead to blindness. There are all sorts of retinitis depending on what the pattern of inflammation looks like, this pattern is often a help to the doctor in diagnosing the cause, as different pathogens produce different patterns.  Retinitis may be caused by a number of different agents. It can be caused by  Heavy metals - lead, silver, aluminium, mercury, cadmium etc which have got into the blood stream and worked their way to the eye.  Retinitis can also be caused by several infectious agents, including toxoplasmosis [parasites], cytomegalovirus [viruses] and candida [fungi]. Cytomegalovirus retinitis is an important cause of blindness in AIDS patients, and is the most common cause of vision loss in AIDS patients. Candida may spread to the retina from the bloodstream, which usually leads to the production of several abscesses in the retina.


It is worth adding that a number of theoretically inherited diseases causing multiple symptoms result in retinitis and hallucinations.  We use the word theoretically, because there is evidence that such diseases are often caused by pathogens that subsequently cause gene mutation.  In other words, the mutation comes later, it is not the cause:

Usher's syndrome is a heterogeneous autosomal recessive disorder characterised by dual sensory impairment: profound congenital hearing impairment and progressive visual loss due to retinitis pigmentosa, sometimes associated with vestibular dysfunction. Some patients develop a psychotic illness, the etiology of which is still debated. Diagnosis may be difficult, and there are only a few reports in the psychiatric literature. PMID: 19540416

Retinitis pigmentosa (RP) is yet another theoretically inherited, degenerative eye disease that causes severe vision impairment  due to the progressive degeneration of the rod photoreceptor cells in the retina. This form of retinal dystrophy manifests initial symptoms independent of age; thus, RP diagnosis occurs anywhere from early infancy to late adulthood.  Again a pathogen may actually be at fault but the symptoms may be gradual gene mutation.

The retina is also subject to problems from Retinal detachments and breaks.



Blepharitis is a common eye condition characterized by chronic inflammation of the eyelid, usually where eyelashes grow, resulting in inflamed, irritated, itchy, and reddened eyelids. It can be caused by the oil glands at the base of the eyelashes becoming clogged, however, it may also be caused by pathogens.

  • Bacterial infection - It is often caused bacterial infection, with one of the main culprits being the staphylococcal bacteria.  There are other bacteria implicated.
  • Parasites - A number of parasites are also implicated in causing blepharitis, eg., Demodex and Phthiriasis palpebrarum. The demodex parasite, if it gets out of control - often as a result of too much grease on the skin, also causes acne and other skin diseases via the bacteria it encourages, as such it needs to be taken seriously

Over a period of nine years (January 2000 to December 2008), 427 cases of demodicidosis were diagnosed. 73.2% of cases were blepharitis and 26.8% of cases were facial dermatosis….. Among 787 chronic blepharitis, 243 cases were due to Demodex sp (30.9%). …. In the face, this mite has been isolated from erythematous and pruritic papulopustular lesions, and their distribution was as follows: cheeks (22.1%), forehead (13.4%), and nose (11.5%). …. there were a large number of arguments for the incrimination of Demodex sp in pathogenesis of dermatosis and blepharitis. PMID: 20596809

What is interesting is that some people succumb to these parasites and some people don’t, which rather implies the immune system is key in protecting us from these pathogens, as are our tears:

Sterile Schirmer test strips were used to collect samples from a group of patients who attended an ophthalmology consultation at the Hospital del Norte, Icod de los Vinos, Tenerife, Canary Islands. Most of the patients (46 individuals, 79.31  %) presented ocular surface pathologies such as blepharitis or conjunctivitis; the rest did not present any pathology. None of the patients included in the study wore contact lenses. …. Molecular analysis classified all isolated strains as belonging to Acanthamoeba genotype tbl4, and .. assays revealed that all strains were potentially pathogenic. PMID: 26293786


no disease
  • Fungi - Fungal infection also appears to be a major cause of this disease, though again the immune system and its effectivenesss appears to play a part

Purpose:  To evaluate the presence of fungi in patients with chronic anterior blepharitis with periodic acid-Schiff (PAS) staining of the eyelashes in addition to the conventional methods of fungal cultures and direct microscopy.
Methods:  Nineteen patients with chronic anterior blepharitis of seborrheic or mixed seborrheic/staphylococcal type and 11 healthy age- and sex-matched controls were included in this prospective, nonrandomized, cross-sectional study.
Result:  We demonstrated fungal elements with PAS staining in 79% of the blepharitis group (hyphae and/or spores) and 18% of the control group. The difference was statistically significant (P=0.002). Four patients in the blepharitis group (21%) had positive cultures for fungi. The isolated fungi were Penicillium species (2 cases), Candida species (1 case), and Trichophyton verrucosum (1 case). Direct microscopic examination revealed Demodex mites in 42.1% of the blepharitis group. No culture growth or Demodex mites were observed in the control group.  PMID:  26293142

Ocular herpes simplex virus (HSV) infection is generally accepted to be a unilateral disease …. We here report an 11-year-old boy with monthly bilateral recurrent HSV type 1 blepharitis for more than 10 years.  PMID:  14562953

but there are a host of others.  Rather interestingly they include viruses that can be passed from mother to child, thus suporting the idea that eye diseases are not 'inherited', they are viral and the virus simply attacks the genes, mutating them over time as the disease progresses:

The viruses able to affect the eye are taxonomically diverse, ranging from double-stranded DNA viruses, to single stranded RNA viruses, to retroviruses. Any part of the eye may be affected, frequently producing blepharitis, conjunctivitis, keratitis, uveitis, cataract and retinitis. The more common ocular viral infections include the Herpesviruses such as HSV-1, VZV and CMV. The HIV pandemic is placing a serious burden on ophthalmology clinics, particularly in sub-Saharan Africa as the number of viral ocular diseases is increasing.  PMID: 23797960



Keratitis is a condition in which the eye's cornea, the front part of the eye, becomes inflamed. The condition is often marked by moderate to intense pain and usually involves impaired eyesight, photophobia, red eye and a 'gritty' sensation.

The medical profession have rather helpfully started to classify the types of keratitis by the cause – a much simpler system and more likely to lead to healing as opposed to simply symptom alleviation.  So what causes Keratitis?

  • Viral infection – more or less the same viruses that we saw for Retinitis and Blepharitis also cause keratitis.  Herpes simplex keratitis is caused by the herpes simplex virus which frequently leaves what is called a 'dendritic ulcer'. Herpes zoster keratitis, is caused by the Herpes zoster virus and often accompanies Shingles.
  • Bacterial infection - Bacterial keratitis  can follow from an injury or from wearing contact lenses. The bacteria often involved are Staphylococcus aureus and for contact lens wearers, Pseudomonas aeruginosa. Pseudomonas aeruginosa contains enzymes that can digest the cornea.  Given that the eye is one unit there may be reasons to implicate this bacteria in some of the other diseases as well.
  • Fungal infection - Fungal keratitis has been caused by contact lens solution, but it is not the only source. 

Fungal infections of the eye are an important cause of significant visual loss and blindness in some regions of the world, especially developing countries. Ocular mycoses remain a diagnostic and therapeutic challenge to the ophthalmologist. Corneal infection is the most frequent presentation, but the orbit, eyelids, lacrimal apparatus, conjunctiva, sclera and internal structures of the eye can also be affected. Candida spp., Fusarium spp. and Aspergillus spp. are the most frequently isolated organisms in fungal keratitis and in endophthalmitis.  PMID: 26771986

  • Pharmaceuticals and toxins  – Pharmaceuticals and toxins are implicated in numerous eye diseases of which keratitis is but one.  In the following it is helpful to know that Hydroxychloroquine is actually an antimalarial drug, but appears to be used to “reduce inflammation in the treatment of rheumatoid arthritis and lupus”.  Bisphosphonates are used to treat osteoporosis and cortocosteriods are immunosuppressants:

Eye involvement represents a common finding in patients with systemic autoimmune diseases, particularly  rheumatoid arthritis, Sjogren syndrome, seronegative spondyloarthropathy, and antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis. …. The eye injury may be .... infectious, as well as iatrogenic, as in the case of hydroxychloroquine, chloroquine, corticosteroids, and bisphosphonates. PMID:  2649448

August Natterer

Thus a number of so called ‘auto-immune’ diseases also come with eye problems.  None of the ones listed are caused by the immune system – all are caused by pathogens.  The standard form of treatment for diseases classified as ‘auto-immune’ is to provide various forms of immunosuppressants.  Immunosuppressants suppress the immune system.   By doing so the actual pathogen causing the disease spreads and any pathogens already on the eye or around the eye are also allowed to grow uncontrollably.  The result is eye disease and sometimes very nasty eye disease………..

Manifestations may affect different components of the eye, with episcleritis involving the episclera, a thin layer of tissue covering the sclera; scleritis being an inflammation of the sclera potentially leading to blindness; keratitis, referring to corneal inflammation frequently associated with scleritis; and uveitis as the inflammation of the uvea, including the iris, ciliary body, and choroid, subdivided into anterior, posterior, or panuveitis. As blindness may result from the eye involvement, clinicians should be aware of the possible manifestations and their management.  PMID:  2649448

So by giving people immunosuppressants you could make them blind.

Iatrogenesis  is defined as “any effect on a person, resulting from any activity of one or more persons acting as healthcare professionals or promoting products or services as beneficial to health, that does not support a goal of the person affected”.

Corticosteroids [immunosuppressants] often induce a variety of psychiatric symptoms, such as alterations of mood, neuropsychological deficits and even psychotic states. ….. Fifty ophthalmologic patients participated in this prospective study. They received methylprednisolone or fluocortolone at doses of 119 +/- 41 mg/day in the beginning and 75 +/- 22 mg after 8 days of treatment. …. a significant proportion of patients suffered from an organic mood disorder, 26-34% experienced a hypomanic syndrome, 10-12% a depressive syndrome. PMID:  8778901

so blind and psychotic.

  • Amoebic - Acanthamoebic keratitis is Amoebic infection of the cornea and is a serious corneal infection, again often affecting contact lens wearers. It is usually caused by Acanthamoeba. On May 25, 2007, the CDC issued a health advisory due to increased risk of Acanthamoeba keratitis (AK) associated with use of Advanced Medical Optics (AMO) Complete Moisture Plus Multi-Purpose eye solution. Acanthamoeba has two evolutive forms, the metabolically active trophozoite and a dormant, stress resistant cyst. Thus cysts in the eye might be formed from these tiny creatures.  Trophozoites are small, usually 15 to 35 μm in length and amoeboid in shape. In nature, Acanthamoeba species are free-living bacterivores, in effect their prey is bacteria which they eat, but in certain situations they can cause infections in humans.  There is the possibility they eat bacteria in the eye.


Onchocerciasis, also known as river blindness and Robles disease, is a disease caused by infection with the parasitic worm Onchocerca volvulus. Symptoms include severe itching, bumps under the skin, and blindness. It is the second most common cause of blindness due to infection, after trachoma.

The parasite worm is spread by the bites of a black fly of the Simulium type. Usually many bites are required before infection occurs. These flies live near rivers, hence the name of the disease. Once inside a person, the worms create larvae that make their way out to the skin. Here they can infect the next black fly that bites the person. 

About 17 to 25 million people are infected with river blindness, with approximately 0.8 million having some amount of loss of vision.  Onchocerciasis is also linked to epilepsy [hence the hallucinations etc] and to the strange symptom of 'nodding'.



Trachoma, also called granular conjunctivitis, Egyptian ophthalmia, and blinding trachoma, is an infectious disease caused by the bacterium Chlamydia trachomatis.

A little more detail on this disease can be found by following the LINK, but all the observations are provided here, as this way they can be seen in the context of the other diseases.


Conjunctivitis, also known as pink eye is inflammation of the conjunctiva (the outermost layer of the eye and the inner surface of the eyelids). It is commonly due to an infection - usually viral, but sometimes bacterial or parasitic, or an allergic reaction to toxins or pharmaceuticals.  Conjunctivitis can affect one or both eyes and is the most likely diagnosis in someone with eye redness and discharge (fluid coming from the eye). The affected eye is often "stuck shut" in the morning.

  • Viral conjunctivitis  - is often associated with an infection of the upper respiratory tract, usually associated with the rhinovirus, or “human coronavirus adenoviruses, the syncytial virus, enteroviruses and metapneumovirus”.  Some other viruses that can infect the eye include Herpes simplex virus and Varicella zoster.  One of the most common cause of viral conjunctivitis are adenoviruses.  Acute hemorrhagic conjunctivitis is caused by one of two enteroviruses, Enterovirus 70 and Coxsackievirus A24.
  • Bacterial infection - Common bacteria responsible for non-acute bacterial conjunctivitis are Staphylococci and Streptococci.  Bacteria such as Chlamydia trachomatis or Moraxella can also cause persistent conjunctivitis without much redness. Other cases of bacterial conjunctivitis are associated with Neisseria gonorrhoeae, β-hemolytic streptococci, Corynebacterium diphtheria, Haemophilus influenzae.  Hyperacute cases are usually caused by Neisseria gonorrhoeae or N. meningitidis.
  • Toxins and allergens - Conjunctivitis may also be caused by allergens such as pollen, perfumes, cosmetics, smoke, dust mites, and eye drops.
  • Mites and parasites – can cause conjunctivitis, for example, Neotrombicula autumnalis (trombiculid mite)
  • Fungal infection - exactly the same fungi as mentionned above are implicated, for example

We report a case of allergic fungal sinusitis (AFS) involving the lacrimal sac………..A 70-year-old white man with a history of chronic conjunctivitis and nasal polyps presenting with chronic epiphora was found to have dacryostenosis on the left side. A CT scan of the orbits revealed mucoperiosteal thickening completely obliterating the frontal, ethmoid and sphenoid sinuses.  PMID:  24832182


I hope that you can now see the pattern.  Pathogens do not confine themselves to one part of the eye, or just the eye, they can spread all over the place in our bodies if our immune system is compromised at any time.  Nasal sprays, for example, can compromise the immune system.  Thus let us suppose this man used a nasal spray, for what he thought was an allergy but which was actually a polyp, containing an immunosuppressant.  The nasal spray would have enabled the fungal infection to spread to his sinuses and eventually to the eye.  All these parts are inter connected.

We have Ear, Nose and Throat specialists, but perhaps it might be better to have pathogen specialists who did a thorough search all over the body for a pathogen. 

Styes and chalazia

An external stye is an infection of the sebaceous glands of Zeis at the base of the eyelashes, or an infection of the apocrine sweat glands of Moll. External styes form on the outside of the lids and can be seen as small red bumps. Internal styes are infections of the meibomian sebaceous glands lining the inside of the eyelids. They also cause a red bump underneath the lid with only generalized redness and swelling visible on the outside. Styes are similar to chalazia, but they tend to be smaller and more painful, Styes are usually caused by the Staphylococcus aureus bacterium, Chalazia by parasites or amoeba.


Uveitis is the inflammation of the uvea, the pigmented layer that lies between the inner retina and the outer fibrous layer composed of the sclera and cornea. The uvea consists of the middle layer of pigmented vascular structures of the eye and includes the iris, ciliary body, and choroid. Uveitis is an ophthalmic emergency and requires a thorough examination by an optometrist or ophthalmologist and urgent treatment to control the inflammation.  The causes are as above for all the other diseases - fungi, bacteria, viruses, pharmaceuticals, toxins and parasites.



As you should be able to see from the descriptions above, the main causes of eye disease are

It is always the same.  It is extremely clear from reading the literature that a fair number of the medical profession seem unaware that if you suppress the immune system, infection in the body and on the body will get worse. It may seem somewhat obvious to you or I, but it appears that there are medical professions unable to see this, for example:

In more severe cases, antihistamines may be prescribed for allergic conjunctivitis and persistent cases may also require topical steroid drops”.

Immunosuppressants and ant-histamines do not cure anything, they simply squash the symptoms - and the symptoms are caused by the immune system at work.   Anti-biotics have an extremely negative effect on the intestinal microflora and as a consequence the intestinal bacteria, which act as a defence against viruses and other pathogens, can be destroyed; whereas the viruses, parasites and other pathogens are not.  Thus the use of oral antibiotics at any time is very very unwise, as if they do succeed in wiping out our intestinal flora, we have left ourselves open to a wholescale invasion by parasites, viruses and 'unfriendly bacteria'.


Note that Drug-induced glaucoma is also called Corticosteroid induced glaucoma and corticosteroids are immunosuppressants.

We also need to squash the red herring that ‘Positive family history is a risk factor for glaucoma etc etc’.

 It isn’t. 

It means the family are exposed to the same pathogens or that behaviourally they have adopted the same pattern of behaviour leading to the pathogen’s entry.  Once there, the pathogen may indeed cause mutations.  Glaucoma, particularly primary open-angle glaucoma, is associated with mutations in several genes (including MYOC, ASB10, WDR36, NTF4, and TBK1 genes), but as it says on PubMed “most cases of glaucoma do not involve these genetic mutations. “  Another cause is damage to the fetus in the womb, but there again what damaged the fetus? – a pathogen or one of the other causes such as radiation.

So to this can be added the other causes:


Find the cause.


How it works

In general all spiritual experiences are being caused by  Sensory deprivation.
