Retinitis Pigmentosa and its Treatment

What is Retinitis Pigmentosa?

Retinitis pigmentosa (RP) is a group of inherited conditions affecting the retina. It can cause progressive loss of night vision and peripheral vision. The age at onset and the course of vision loss vary between people.

Read the National Eye Institute’s RP overview for general background, and discuss your diagnosis with an eye specialist.

Epidemiology

Worldwide there are more than five million people suffering from various forms of Retinitis Pigmentosa Cure. Often; RP appears in childhood / adolescence or in the middle ages with first symptom night blindness ; visual field and vision acuity decrease progressively. Most often the deterioration process is gradually. However; it can also lead to blindness stage very quickly. Slow deterioration of the disease is often associated with a physical concern. Almost sixty percent of RP patients develop cataract until adulthood.

Retinitis Pigmentosa Cure is a form of retinal dystrophies, and is caused by irregularity of photoreceptors ( rod and cone cells) or the retinal pigment epithelium of the retina ; giving rise to continuous vision loss and blindness.

There are two types of receptor dystrophies:

01

Rod dystrophy

Patients suffering from rod dystrophy have peripheral sight loss. These are the patients with tunnel vision. Night blindness stands in foreground.
02

Cone dystrophy

(dystrophy of cone cells, which are responsible for both central and color vision)

RP patients with cone dystrophy develop central vision loss and poor color vision.

There are many patients suffering from Rod-Cone dystrophy and both their peripheral and central vision are deteriorated or deteriorate gradually.

Signs, symptoms and Prognose of Retinitis Pigmentosa

Some of the possible symptoms of Retinitis Pigmentosa are :

  • Night blindness and Nyctalopia (insufficient adaptation to darkness)
  • Longer adaptation time (slow adjustment from dark to light or the opposite)
  • most often patients with RP can read white letters from black background better.
  • insufficient color discrimination ; failure of color perception
  • flickering vision ( Latticework vision)
  • blurring of vision
  • tunnel vision ( only central vision ; inability of peripheral sight)
  • peripheral vision ( inability of central vision; patients can’t see the details and have reading difficulties)
  • Visual field impairment, particularly in peripheric vision. Central vision survives at the beginning which causes tunnel vision. After the impairment of peripheric vision; central vision start to be deteriorated and this results in blindness at the end.
  • Myopie Magna ( high degrees of myopia ;more than 6 dpt ; not only far distance impairment but patients can also can’t see objects clearly that are away from 1 meter )
  • Astigmatism
  • Flashes and lightning in vision

In general , first symptom appearing is night blindness ,vision impairment and a slow decrease of visual field until a very tiny tunnel vision. In time the disease leads to blindness. Because of night blindness and always more declining tunnel vision ; after a particular time patients can not move alone without orientation strategies.

Retinitis Pigmentosa is a disease characterised by dysfunction of the light sensing photoreceptor cells (rod and cone cells) .Usually the rod cells ( responsible for night vision) are damaged at first, which explains why night blindness the first symptom is .Daytime vision loss ( cone cells are responsible for daytime vision ) doesn’t appear until the later stages of the disease. Stippling of the retinal pigment epithelium with black bone-spicule pigmentation is typically pathognomonic of retinitis pigments . Other ocular features are waxy pallor of the optic nerve head, attenuation( thinning) of the retinal vessels , cystic macular inflammation ( oedema) and posterior subcapsular cataract.

Complications:

  • Cataract
  • cystic macular inflammation and macular degeneration
  • Myopic
  • Astigmatism
  • Nystagmus
  • Glaucoma
  • Keratoconus

Genetic

More than 150 Gene play an important role in pathogenesis of Retinitis Pigmentosa. Most of the so far identified genes have a monogenetic inheritance, which means the defect of just one gene can lead to Retinitis Pigmentosa, whereas more genes together can also cause the same problem. The disease can follow through autosomal rezessive, dominant and gonosomal inheritance.

How do the mutations effect?

Some mutations operate through photoreceptors. These mutations have a destructive or function ruining effect on the receptor cells. Some photoreceptor cells are killed due to apoptosis where some of them just lose their function.

Other mutations have an affect on the function of RNA Splycing Complex.

Besides mutations; the disturbance of retinal blood vessels cause impairment of disease.

Associated conditions with Retinitis Pigmentosa Cure

RP is seen in a variety of diseases combined. Beside eyes there are also other organs involved with these syndromes. Therefore we can say, that Retinitis Pigmentosa Cure is a systemic disease. Some well known with RP combined symptoms are hearing disorders, paralysis, muscle weakness, migraine etc.


The most well known Syndroms are:

01

Usher Syndrom

Retinitis Pigmentosa combined with congenital or progressive deafness. There are three types of Usher Syndrome.

  • Usher Syndrome typ 1 : typ1 is the heaviest of all types. Patients are deaf from birth and Retinitis Pigmentosa can be until 10th year diagnosed.
  • Usher Syndrome typ 2 : there is a constant remaining but severely deafness, and RP will during adolescence diagnosed.
  • Usher Syndrome typ 3 : this is a mild form of Usher Syndrome and Retinitis Pigmentosa will most probably only in second half of life diagnosed.

Usher Syndrome treatment :


With our treatment of electro-acupuncture we successfully treat all types of Usher Syndrome. We have significant improvements on deafness and night blindness ( Retinitis Pigmentosa )
02

Bardet Biedl Syndrome :

Laurence Moon Bardet Biedl Syndrome is also a genetic disease.

Bardet-Biedl Syndrome characteristics:
  • Obesity
  • Diabetes Mellitus
  • Hypertension
  • Hypogenesis of Penis etc. ; Hypogonadism
  • Retinitis Pigmentosa and therefore resulting blindness
  • cognitive disability ( mental retardation )
  • polydactily (more than five fingers ; usually six)

Treatment of Bardet-Biedl Syndrome

Our technique provides significant improvements on obesity, Retinitis Pigmentosa , hypertension of Bardet Biedl Syndrome.

03

Refsum Syndrome

Over-Accumulation of Phytanic Acid in cells and tissues causes Refsum Disease. Patients with Refsum Disease may have several different degrees of neurologic damage and peripheral neuropathy. In common; the disease appears in childhood/adolescence with a progressive course. Symptoms also may include ataxia, hearing difficulties and eye problems such as cataracts, night blindness ( Retinitis Pigmentosa).

With our treatment there has been significant improvement seen on Retinitis Pigmentosa ( larger visual field , improved vision acuity etc ) and on phytanic acid levels. We have determined that the other neurologic and skin issues have also improved during our treatment.
04

Alport Syndrome

Alport syndrome is a genetic disorder characterised by glomerulonephritis, and hearing loss. It can also affect the eyes. Hematuria is almost always present in the urine (blood in the urine due to glomerulonephritis) Some patients can also suffer from Retinitis Pigmentosa associated with Alport Syndrome.

Diagnosis and ongoing care

Assessment may include a dilated eye examination, visual field testing, retinal imaging, electroretinography and genetic testing. Your eye specialist can explain which tests are relevant to your situation.

Low-vision aids, rehabilitation and regular eye examinations can support ongoing care. Source: National Eye Institute.

Care options and treatment research

Care and research options depend on the diagnosis. Distinguish established care, treatments for specific genetic conditions and experimental approaches when discussing your options with a retinal specialist.

01

Gene therapy: a specific indication

The FDA lists LUXTURNA for patients with confirmed biallelic RPE65 mutation-associated retinal dystrophy. Patients must have viable retinal cells as determined by the treating physician. This is not a treatment for every form of RP.

This approval does not establish the effectiveness of electro-acupuncture and does not mean that Fıratlı Clinic provides LUXTURNA.

02

Discussing care and research

Ask your retinal specialist about available care, the evidence for a proposed intervention and whether a research study is relevant to your diagnosis. Study participation and treatment eligibility require individual assessment.

Read how Fıratlı Clinic describes its method and ask the clinic about evidence, limitations and follow-up.

Retinitis Pigmentosa: questions for patients and families

Understanding a diagnosis is the first step in deciding what information and support you need. This guide connects general RP information with the practical questions to ask before a clinic visit.

Why can RP affect people differently?

RP is associated with different genetic changes and patterns of inheritance. An eye specialist or genetic counsellor can help explain what your diagnosis and test results mean for you and your family.

Which examinations should I discuss?

An assessment may include a dilated eye examination, visual field testing, retinal imaging, electroretinography and genetic testing. Ask your specialist which tests are relevant, and keep copies of existing reports for future consultations.

How can I compare care options?

Ask what an option is intended to achieve, what evidence supports it, what its limitations are and what follow-up is needed. Low-vision aids and rehabilitation can support everyday activities. General disease information and an individual patient story serve different purposes.

Considering a visit to Fıratlı Clinic?

Read the clinic’s method information, explore patient experiences and send a consultation enquiry. Ask which records are needed before booking travel. You can also read the international visitor guide.
