Fighting Blindness has funded Target 5000 to date, however it was always our aim that this genetic testing be taken as a human rights based approach. Our members rely on hospital consultants to implement the programme. Fighting Blindness has no operational control, and cannot interfere with the process.
Always contact your consultant or health care professional.
Contact details for the three Target 5000 sites can be found below.

Anyone with an inherited retinal degeneration is eligible for Target 5000. Inherited retinal degenerations, also called inherited retinopathies, refer to a group of often rare conditions in which defects in genes lead to photoreceptor cell death and associated vision loss.
If you are unsure as to whether you have an inherited retinal degeneration, please consult your eye doctor.
In total, the appointment may take up to four hours.
You will be asked to attend a follow-up appointment to establish the presentation of your condition over time. Follow-up assessments are an essential part of every individual’s clinical care and should be sought by every individual diagnosed with an IRD.
While such visits may be lengthy, a lot of valuable information can be collected to assess visual function and the status of your eye condition over time.
This is an important step to allow us to understand your condition more fully and allows us to gain insight as to how the condition presents among individuals with the same or different genetic mutations.

Genetic testing for inherited retinal degenerations is highly complex, with more than 270 genes known to play a role. To put this into perspective, a single gene can consist up to 10,000 or more letters of DNA code.
As you can imagine, this generates a large volume of ‘genetic data’. Genetic experts and computational scientists must read through and interpret this data accurately to find what the underlying genetic cause of your condition is. Understandably, this can often take time to pinpoint the disease-associated mutation.
Unfortunately, it is impossible to predict how long it will take to find the mutation that causes your inherited retinal degeneration as this will differ greatly from person to person, depending on the gene involved. If you have a very uncommon mutation, this may take longer for scientist to identify.
Please know, every effort is being made to deliver results as quickly as possible.
Genetic testing is in itself a complex process, made all the more challenging on account of the fact that not all genes associated with an IRD have been identified. Usually when a test is returned as negative, it simply means that there isn’t certainty around the potential disease-causing gene or that it hasn’t been identified yet.
However, recent advances have resulted in the discovery of new IRD-associated genes, meaning that genetic testing panels are better equipped to find a genetic cause or association for an IRD. On-going research efforts to identify more genes will greatly improve the chances of receiving a genetic diagnosis.
As part of Target 5000, all samples where the disease causing gene has not yet been identified, are regularly re-analysed as new genes are discovered and research techniques advance and software tools are updated.
It is important to remember that genetic testing techniques and our knowledge of genetics is advancing rapidly. Therefore, even if a mutation cannot be found now, there is still a possibility that new techniques will enable scientists to find it in the future.
Your genetic diagnosis will be delivered by a genetic counsellor. A genetic counsellor is a trained expert who can support individuals in understanding their diagnosis, provide information on the benefits, risks and limitations of the result, and advise on possible next steps.
You will have the opportunity to ask any questions you may have about your diagnosis at your appointment.
If you have attended your Target 5000 appointment and would like an update on the status of your genetic test, you can request an update from the clinic you attended.

It is best to first talk to your eye doctor about getting involved with Target 5000.
You can also register for Target 5000 by contacting the Fighting Blindness research team on 01 6789004 or at target5000@fightingblindness.ie. You will be asked to provide some basic information including some personal details and details about your condition.
This will allow us to make a referral to the Target 5000 clinic. This information is confidential and handled in a manner compliant with GDPR regulations.
The Target 5000 clinic will contact you with details of your appointment.
Fighting Blindness cannot advise of any appointment/clinical details. It is best to contact the Target 5000 site for this information.
