Idiopathic macular telangiectasia type 2 (MacTel): US-approved treatments and how Gulf families can access them

Reviewed by the Reserve Meds clinical operations team on 17 October 2026.

What is MacTel type 2?

Macular telangiectasia type 2 (MacTel) is a rare eye disease that affects the macula, the small central part of the retina that gives sharp, straight-ahead vision. It is the most common type of macular telangiectasia. The most common symptom is a gradual loss of central vision in one or both eyes, with blurry or distorted vision and trouble seeing in dim light. It usually progresses slowly, and side vision is usually kept.^[1]

It is often diagnosed between ages 40 and 50 and is estimated to affect about 0.1 percent of people.^[1]

MacTel type 2 in the Gulf

We did not find published Gulf-specific figures for MacTel, so we do not give any. Encelto was not part of the Gulf register check we ran on 17 October 2026, so we confirm its status for your country when you ask.

Encelto is implanted inside the eye by a qualified eye surgeon, so treatment involves an eye center that can perform the procedure and follow up afterwards.^[2]

How families in the Gulf can access these medicines

For Encelto. These are made for one patient or given through a specialized procedure, so treatment happens at a qualified center. For most Gulf families that means a referral from the treating specialist to a center abroad that can give the treatment. A local hospital can only give it if the manufacturer agrees to supply that hospital and the regulator approves the import. We cannot promise that a manufacturer will agree.

Who does what

• Your treating specialist decides whether a medicine is right for the patient and writes the letter.
• The hospital checks local supply, files any import request, and gives the treatment safely.
• The national regulator decides whether to approve the import of a medicine that is not registered.
• The manufacturer decides where its medicine can be supplied, especially for cell and gene therapies.
• Reserve Meds helps organize records, coordinates US supply through our wholesale partner, shipping and updates to your family. We do not give medical advice.

Documents you will usually need

• A letter from the treating specialist with the diagnosis, past treatments and why this medicine is being considered
• Reports that confirm the diagnosis, such as genetic, pathology or laboratory results, translated into English where needed
• Recent clinic notes and a list of current medicines
• For a hospital import request: the prescription, the hospital's request form and the written consent of the patient or guardian
• Proof of the US FDA approval and the US prescribing information (we can supply these)

We give you a written timeline estimate once we see the hospital file. The regulator, the treatment center and the manufacturer set their own timelines.
