Macular telangiectasia (MacTel) is an eye condition that affects the macula, the tiny central area of the retina that gives you sharp, straight-ahead vision for reading, recognizing faces, driving, and seeing fine detail.
The word “telangiectasia” means abnormally widened tiny blood vessels (capillaries). In MacTel, some of the small blood vessels around the fovea (the most precise spot in the macula) become dilated, leaky, or irregularly shaped. Over time, these vessel changes are linked with damage to supporting retinal cells, especially Müller cells (the macula’s “nurse” cells), and with thinning or small cavities inside the retina. The end result is blurred or distorted central vision, often slowly progressive over years.
Macular telangiectasia (pronounced “TELL-an-JEK-tay-zee-uh”) is an eye condition that slowly harms the macula, the tiny center of the retina that you use for sharp, straight-ahead vision (reading, faces, fine detail). In MacTel, tiny blood vessels in the macula become abnormal, and over time the light-sensing cells (photoreceptors) can thin and stop working. People usually notice blurred words, wavy lines, or a small dim spot near the center of vision. The condition is typically slow, affects both eyes (often unequally), and most people keep some reading and driving vision for years.EyeWiki
Think of the macula like the focus point of a camera. When the small pipes that feed that point become stretched or leaky, the tissue can get stressed and thinner, and the picture quality drops. That is MacTel in simple terms.
We depend on central vision every day. MacTel usually starts gently, so people may not notice early changes. But with time, it can cause straight lines to look wavy, letters to fade or double, or a smudgy or gray spot in the center of what you see. Early detection helps you track the condition, protect the eye from other causes of vision loss, and treat complications if they arise (for example, when new abnormal vessels grow under the retina).
How doctors currently understand MacTel
Blood vessel problem + support cell problem. In MacTel, the capillaries around the fovea are not normal, and there is degeneration of Müller cells that normally keep the macula healthy.
Neuro-metabolic stress. Research suggests that metabolic imbalance in the retina (for example, low serine and toxic fats called deoxysphingolipids) might injure retinal cells and vessels in some people.
Slow and often subtle. Many people have slow, bilateral (both eyes) change, with patchy parafoveal (around the center) involvement.
Complications can occur. A smaller group develops new abnormal blood vessels under the retina (subretinal neovascularization), which can cause quicker vision loss but can sometimes be treated.
You do not need to memorize these terms. The key point: MacTel is a long-term, central retina condition where tiny vessels and support cells are unhealthy, leading to gradual central vision changes.
Types of Macular Telangiectasia
Doctors group MacTel into types because each type behaves a bit differently. The type number is not a “stage”—it’s a pattern of disease.
1) Type 1 (Aneurysmal or “exudative” MacTel)
Who/How: Often one eye, typically men, and usually more leakage of fluid and lipid (exudate).
What’s happening: The tiny vessels develop bulges (micro-aneurysms) and leak.
What it looks like: Hard exudates (yellowish deposits), retinal swelling, and obvious leaky spots on dye tests.
Key idea: This type is more like a focal vessel leakage problem near the fovea.
2) Type 2 (Idiopathic parafoveal MacTel; the most common)
Who/How: Usually both eyes, slow progression, often middle age or later.
What’s happening: Parafoveal capillaries become dilated and irregular, but leakage is often subtle. The retinal tissue thins, forms tiny inner retinal cavities, and support (Müller) cells are lost.
What it looks like: Grayish loss of retinal transparency near the fovea, right-angled veins, crystalline deposits in some, pigment clumps later, and characteristic OCT changes (little cavities, “ILM drape” sign).
Complication risk: Some develop neovascularization (new abnormal vessels) under the retina that may need treatment.
Key idea: This type is a mixed vessel-and-retinal support cell disorder with slow central vision changes.
3) Type 3 (Rare, occlusive MacTel)
Who/How: Very uncommon, sometimes both eyes, and may be associated with wider vascular problems in the retina.
What’s happening: Capillary closure (not just dilation), leading to poor blood flow and retinal damage.
Key idea: A rare, more severe vascular problem with a risk of ischemia (lack of oxygen) in the central retina.
Possible causes and contributors
Important note: In many people, MacTel—especially Type 2—is idiopathic, which means we cannot point to one single cause. The list below includes drivers and risk factors that may contribute in some individuals. Not everyone will have these.
Idiopathic origin – In many cases, no single clear cause is found.
Müller cell dysfunction – The macula’s support cells become unhealthy, reducing nutrient balance and structural support.
Abnormal tiny blood vessels – Capillaries become dilated, fragile, and irregular, stressing nearby tissue.
Metabolic stress in the retina – The macula’s energy balance can be off, harming cells that need steady fuel.
Low serine levels – Some people may have low serine (an amino acid) linked to toxic lipid by-products.
Deoxysphingolipids accumulation – Toxic fats can build up and harm retinal neurons and vessels.
Oxidative stress – Reactive oxygen can damage delicate macular cells over time.
Chronic low-grade inflammation – Subtle, long-term inflammation may weaken capillaries and retinal tissue.
Age-related vulnerability – MacTel is more common later in life, when tissues are less resilient.
Genetic susceptibility – Family tendencies or rare gene variants can increase risk in some.
Diabetes or prediabetes – Glucose dysregulation may add vascular stress (though MacTel is not the same as diabetic macular disease).
High blood pressure – Long-term pressure on small vessels can make them fragile or leaky.
High cholesterol or triglycerides – Unhealthy lipid patterns can injure small retinal vessels.
Smoking – Smoking increases oxidative stress and vascular injury in the eye.
Metabolic syndrome / obesity – Systemic metabolic imbalance can stress the retinal micro-environment.
Poor diet quality – Diets low in key amino acids and antioxidants may reduce retinal resilience.
Hormonal factors – Hormonal shifts may modulate vessel tone and cell metabolism.
Light/phototoxic stress – Excessive cumulative light exposure can strain macular cells.
High myopia (very nearsighted) – Stretched retinal tissue may be more vulnerable to microvascular issues.
Autoimmune or systemic vascular conditions – Certain body-wide conditions can alter small vessels or trigger inflammation that reaches the retina.
No single item above proves you will get MacTel. They are possible contributors that may add up differently in each person.
Common symptoms
Symptoms can be mild at first and affect both eyes (often unevenly). They usually develop slowly.
Blurry central vision – Words on a page or faces look soft or out of focus.
Metamorphopsia – Straight lines look wavy or bent (for example, door frames or grid lines).
Paracentral smudge/spot – A gray or faded patch near the center that interferes with reading.
Difficulty reading small print – You need more light or larger font to read comfortably.
Reduced contrast – Faint or low-contrast text vanishes more easily than before.
Colors look washed-out – Color saturation may seem less vivid.
Micropsia/macropsia – Objects can look smaller (micropsia) or bigger (macropsia) than they are.
Glare sensitivity – Bright lights or headlights cause discomfort and reduced clarity.
Trouble in dim light – Low-light tasks (restaurants, dusk) become harder.
Reading speed drops – You lose place or need to reread lines.
Faces harder to recognize – Central blur makes facial features less clear.
Intermittent distortion – Symptoms may fluctuate day to day or with fatigue.
Central shadow – A fixed central gray spot that doesn’t move with blinking.
Eye strain or headaches – From squinting or leaning in to see detail.
Depth and alignment confusion – Fine tasks (threading a needle) feel trickier than before.
Call an eye specialist promptly if you notice new sudden distortion, a rapid drop in vision, or a dark patch that grows—these can signal complications that might be treatable.
Diagnostic tests
Doctors use a mix of clinic checks and imaging to confirm MacTel and to separate it from look-alike conditions. Below are tests, grouped into Physical Exam, Manual Tests, Lab/Pathology, Electrodiagnostic, and Imaging. You will not need every test; your doctor chooses what fits your situation.
A) Physical Exam
Best-corrected visual acuity (BCVA)
You read letters on a chart with your best glasses. This shows how sharp your central vision is right now and helps track change over time.Dilated slit-lamp biomicroscopy of the macula
Your pupil is dilated with drops. The doctor looks at your macula with a microscope and special lens, checking for loss of transparency, tiny vessel changes, crystalline deposits, pigment clumps, or swelling.Confrontation or central field check
You cover one eye and look at a target while the clinician maps missing or dim spots near the center. It’s a quick way to gauge paracentral scotomas (blind spots).Pupil reactions and basic neurologic eye checks
Simple checks for pupil symmetry and responses help confirm the problem is in the retina, not the optic nerve or brain.
B) Manual Tests
Amsler grid
You look at a square grid (like graph paper) one eye at a time. If lines look wavy, broken, or missing, that signals macular dysfunction. Many people also use this at home to monitor.Reading performance (e.g., MNREAD)
A short reading task measures reading speed and comfort. MacTel often slows reading even before large acuity changes.Contrast sensitivity (e.g., Pelli-Robson chart)
This chart uses letters that fade in contrast. People with MacTel may read high-contrast letters but struggle when contrast is low, revealing everyday difficulties (faint print, gray-on-white text).Color vision screening (Ishihara or D-15)
Color plates or disks check if color discrimination is reduced, which some MacTel patients notice as washed-out colors.
C) Lab and Pathological Tests
Fasting glucose and HbA1c
These blood tests check for diabetes or prediabetes, conditions that can stress the retinal micro-vessels and co-exist with MacTel.Lipid profile (cholesterol, triglycerides)
Abnormal blood lipids can reflect systemic vascular risk, helpful for overall eye and body health management.Plasma serine and deoxysphingolipids (specialized lab)
In some patients with MacTel, low serine and toxic deoxysphingolipids are found. While not part of everyday care everywhere, these tests support the metabolic link when available.Targeted genetic testing (research-guided)
If there’s a strong family pattern or research interest, doctors may consider gene panels linked to serine biosynthesis or lipid handling. This is not routine but can be discussed.
D) Electrodiagnostic Tests
Multifocal electroretinography (mfERG)
Tiny electrodes record how small patches of your central retina respond to light. In MacTel, central responses can be reduced, matching your symptoms.Full-field electroretinography (ERG)
This tests the entire retina’s electrical response. In many MacTel patients, overall retina is fairly normal, helping rule out diffuse retinal diseases.Electro-oculography (EOG)
This measures RPE (retinal pigment epithelium) function. Results can be normal or mildly altered, adding context to other tests.
E) Imaging Tests
Optical coherence tomography (OCT)
This painless scan slices the macula into microscopic cross-sections. In MacTel Type 2, doctors often see inner retinal cavities, thinning, and the “ILM drape” (the inner surface draped over a cavity). OCT is central to diagnosis and follow-up.OCT angiography (OCTA)
OCTA maps blood flow in the retina without dye. It can show abnormal tiny vessels around the fovea and detect new subretinal vessels early, guiding timely treatment if they appear.Fluorescein angiography (FA)
A small amount of fluorescent dye is injected into a vein. Photos track dye as it moves through retinal vessels. MacTel shows telangiectasia, late staining, and sometimes leakage. FA is very helpful to confirm patterns and rule out mimics.Fundus autofluorescence (FAF)
This imaging makes the retina glow naturally to show RPE health. In MacTel, parafoveal changes in autofluorescence help map the disease area and monitor progression.Color fundus photography (including widefield when useful)
Standard photos document crystalline deposits, pigment clumps, vessel changes, and overall macular appearance so changes can be compared over time.
Treatments
ENCELTO (revakinagene taroretcel-lwey) — the first FDA-approved treatment (March 2025) for adults with MacTel type 2. It’s a tiny encapsulated cell implant that continuously releases CNTF, a nerve-support protein, inside the eye. In two phase-3 trials it significantly slowed photoreceptor loss over 24 months vs. sham surgery. Dose: one implant per affected eye placed surgically into the vitreous. Key risks are from the procedure (eg, infection, retinal tear/detachment, vitreous hemorrhage) and delayed dark adaptation.U.S. Food and Drug Administration+2U.S. Food and Drug Administration+2
Anti-VEGF injections (bevacizumab, ranibizumab, aflibercept, etc.) — only when “wet” MacTel develops (macular neovascularization). In that stage, anti-VEGF improves or stabilizes vision and dries leakage; in non-neovascular MacTel, these drugs don’t change long-term outcomes and are not used.PMCLippincott Journalsclinicaloptometry.scholasticahq.com
Investigational metabolic approaches — L-serine supplementation and fenofibrate are being tested to lower toxic deoxysphingolipids; as of now, these are clinical-trial only (no proven visual benefit yet).ClinicalTrialslmri.net

Drug treatments
Important: Only two categories have strong clinical roles today:
(A) ENCELTO to slow photoreceptor loss in eligible non-neovascular MacTel type 2; and
(B) Anti-VEGF injections for the neovascular (“wet”) stage. Others below are adjuncts or investigational.
ENCELTO (revakinagene taroretcel-lwey, NT-501) — FDA-approved
Class: Allogeneic encapsulated-cell gene therapy releasing CNTF.
Dose/Timing: One implant per affected eye, surgical intravitreal placement by a qualified ophthalmologist.U.S. Food and Drug AdministrationDailyMed
Purpose: Slow progression (preserve photoreceptors/structure and related function).
How it works: Continuous CNTF delivery likely supports Müller cells/photoreceptors and slows EZ loss.
Key side effects/risks: From surgery and device: endophthalmitis, retinal tear/detachment, vitreous hemorrhage, implant extrusion, suture problems, cataract, and delayed dark adaptation; see patient instructions and label.U.S. Food and Drug Administration+1Bevacizumab (anti-VEGF) — for neovascular MacTel only
Class: VEGF inhibitor (off-label in MacTel).
Dose/Timing: Treat-extend-stop patterns individualized (monthly to q6-8wk after loading; clinic-specific).
Purpose: Dry fluid, stop bleeding, improve/stabilize vision in proliferative MacTel.
Mechanism: Blocks VEGF to shut down abnormal new vessels.
Main risks: Injection-related (infection, pressure spikes), rare stroke risk debated. Evidence supports benefit when MNV is present.Lippincott Journalsclinicaloptometry.scholasticahq.comRanibizumab (anti-VEGF) — neovascular MacTel
Similar to #2 with robust experience for MNV; benefits shown in small series.Lippincott JournalsAflibercept (anti-VEGF/VEGF-Trap) — neovascular MacTel
Option for eyes with fluid/bleed; some clinics prefer for tougher leakage.clinicaloptometry.scholasticahq.comFaricimab (dual Ang-2/VEGF) — neovascular MacTel, emerging use
Status: Not MacTel-specific RCTs; used by analogy to other retinal neovascular diseases when MNV behaves stubbornly. Evidence base in MacTel is limited. (Clinician-judgment item.)Topical or periocular steroids
Status: Not standard for non-neovascular MacTel; may be considered for inflammatory overlays but no evidence they change MacTel course. (Contextual/avoid routine use.)Carbonic anhydrase inhibitors (acetazolamide/dorzolamide)
Status: Sometimes tried off-label to reduce cystoid spaces in other retinopathies; no proven benefit for classic MacTel cavitations (which are degenerative, not fluid-filled). (Avoid routine use.)L-serine (oral) — investigational
Class: Amino-acid therapy aimed at lowering toxic deoxysphingolipids.
Dose in trials: 200–400 mg/kg/day (varies).
Status: Phase 2a SAFE study ongoing; no established visual benefit yet; discuss only in trial settings.ClinicalTrialsCenterWatchFenofibrate — investigational metabolic adjunct
Class: PPAR-α agonist; improves lipid handling.
Aim: Lower deoxysphingolipids in blood with/without serine.
Status: Phase 2a SAFE (with serine) underway; not standard care for MacTel per se.ClinicalTrialsNutraceutical carotenoids (lutein/zeaxanthin)
Status: In MacTel, raising macular pigment does not restore the normal central pattern or improve vision, and high-dose zeaxanthin has even produced reversible crystalline deposits in a case series. Use caution; not a MacTel treatment.PubMed
Dietary “molecular” and supportive supplements
There is no proven supplement that treats MacTel. The best evidence-based “metabolic” strategy is participating in clinical trials (eg, serine ± fenofibrate). Items below list common doses used for general eye/health support; always confirm safety with your doctor (drug interactions, kidney/liver issues, pregnancy).
L-serine (trial-only for MacTel): studied at 200–400 mg/kg/day divided; goal is lower toxic deoxysphingolipids. Not standard outside trials.ClinicalTrials
Glycine (adjacent to serine pathway): typical general doses 1–3 g/day; theoretical support only.
Omega-3 (EPA/DHA fish oil): 1–2 g/day combined EPA+DHA; cardiovascular and anti-inflammatory support.
Lutein: 10 mg/day; supports macular pigment in general, but does not fix MacTel pigment loss.
Meso-zeaxanthin/Zeaxanthin: 2 mg/10–20 mg/day; no visual benefit shown in MacTel; caution with high dose.PubMed
Vitamin D3: 1,000–2,000 IU/day if deficient; systemic health.
Vitamin B12 + Folate + B6: homocysteine support if low or deficient.
Magnesium: 200–400 mg/day; sleep/cramp support; watch kidneys.
CoQ10 (Ubiquinol): 100–200 mg/day; mitochondrial support.
Curcumin: 500–1,000 mg/day with piperine (watch interactions).
Resveratrol: 100–250 mg/day; general antioxidant; limited ocular evidence.
Taurine: 500–1,000 mg/day; retinal nutrient in animals; human data limited.
Alpha-lipoic acid: 300–600 mg/day; neuropathy/antioxidant support.
Zinc: 10–25 mg/day (do not exceed long-term without supervision).
General multivitamin: a safe baseline if diet is inconsistent.
Key reminder: For MacTel, serine ± fenofibrate is the only supplement/drug strategy being clinically tested for the disease mechanism; others are for general health and do not have MacTel-specific proof.ClinicalTrials
Regenerative / stem-cell / neuroprotective” approaches
Today there is one approved neuroprotective therapy. The rest should be trial-only.
ENCELTO (CNTF-secreting encapsulated-cell implant) — approved; slows photoreceptor loss in MacTel type 2. See dosing/risks above.U.S. Food and Drug Administration+1
Other encapsulated-cell platforms (research) — same concept (living cells release neurotrophins) being explored for other retinal diseases; not MacTel-approved.
Photoreceptor cell replacement (stem-cell-derived) — experimental for macular diseases; not approved for MacTel; only in regulated trials (avoid “clinic” offerings).
RPE cell therapy — experimental; small AMD studies exist; no MacTel approval.
Gene-targeted strategies for serine metabolism — future concept (eg, PHGDH pathway); no clinical products for MacTel yet.PubMed
Other neurotrophic factors (BDNF/GDNF) — preclinical/early-phase ideas; nothing approved for MacTel.
Procedures/surgeries
ENCELTO implantation
What: Outpatient eye surgery; a grain-of-rice-sized capsule is placed inside the eye and sutured to the sclera at the pars plana.
Why: To continuously release CNTF and slow retinal degeneration in eligible MacTel type 2.
Notes: One implant per affected eye; specific surgical steps and removal criteria are detailed in the label.U.S. Food and Drug AdministrationIntravitreal anti-VEGF injections (procedure)
What: Medicine is injected into the eye under sterile conditions (seconds, in clinic).
Why: Treats macular neovascularization (the “wet” phase) to stop bleeding/leak and stabilize or improve vision. Not used in non-neovascular MacTel.Lippincott JournalsPMCPars plana vitrectomy with ILM peel (selected cases)
What: Standard macular-hole surgery.
Why: Rare full-thickness macular hole can occur in MacTel; surgery may help close the hole and improve vision. (Individualized decision.)EyeWikiPhotodynamic therapy or focal laser (rare, case-by-case)
What: Light-activated drug (PDT) or focal laser to abnormal vessels when clearly away from the fovea.
Why: Historically tried; anti-VEGF is preferred for MacTel-related neovascularization; laser near the fovea risks damage. (Specialist judgment.)PMCCataract surgery (when needed)
What: Removes cloudy lens; routine eye surgery.
Why: If cataract adds blur/glare, clearing the lens improves overall vision even though MacTel remains.
Prevention & self-care tips
Keep diabetes, blood pressure, and lipids on target (these are common in MacTel cohorts).EyeWiki
Don’t smoke.
Use UV-blocking sunglasses outdoors (glare control helps).
Eat a Mediterranean-style diet (fish, greens, nuts, legumes, olive oil).
Exercise regularly within your doctor’s advice.
Use an Amsler grid weekly and see your doctor if lines bend or a new gray spot appears.
Keep routine eye visits (OCT/OCTA detect early changes).EyeWiki
Manage screen ergonomics (contrast, zoom, lighting).
Take medicines exactly as prescribed (eg, after ENCELTO surgery or anti-VEGF plans).
Ask about clinical trials if you’re eligible.PentaVision
When to see a doctor urgently
Sudden bend/wave in straight lines, a new dark/gray spot, fresh floaters, flashes, or a drop in central vision. These can signal macular bleeding/leakage or a retinal tear/detachment, which need prompt care.
After ENCELTO surgery: report worsening pain, redness, pus, sudden blur, or strong light-to-dark trouble (delayed dark adaptation can occur; your team will counsel you).U.S. Food and Drug AdministrationMayo Clinic
What to eat and what to avoid
What to eat more of (10 ideas):
Leafy greens (spinach, kale)
Colorful veg & berries (antioxidants)
Fatty fish 2–3×/week (omega-3s)
Legumes & whole grains (steady sugars)
Nuts & seeds (healthy fats)
Eggs (macular-friendly carotenoids)
Lean proteins/soy (serine is abundant in protein foods)
Olive oil instead of butter
Plenty of water
Spices like turmeric/ginger for flavor and anti-inflammatory potential
What to limit/avoid (10 ideas):
Sugary drinks and sweets (sugar spikes stress vessels)
Ultra-processed snacks (trans fats/salt)
Excess alcohol
Smoking/vaping (just don’t)
Very high-glycemic meals (huge white-flour portions)
Excessive salt (BP control)
Large evening caffeine (sleep affects adaptation)
Self-starting high-dose zeaxanthin for MacTel (no proven benefit; one case of reversible crystal deposits at high dose)PubMed
Random online “stem-cell” treatments (unsafe outside trials)
Skipping follow-up (quiet progression is common)
FAQs
Is MacTel the same as macular degeneration?
No. They both affect the macula, but MacTel has its own biology (serine pathway, Müller cell stress).PubMedWill I go blind?
Total blindness is very unlikely. MacTel mainly affects central vision; peripheral vision is usually preserved. Progression is often slow.EyeWikiWhat is the first real treatment for MacTel?
ENCELTO, FDA-approved in March 2025, the first and only approved therapy for adults with MacTel type 2; it slows photoreceptor loss.U.S. Food and Drug AdministrationIf my doctor says “it’s dry now,” do I need shots?
No. Anti-VEGF injections are for the neovascular (“wet”) stage only.PMCWhat if it turns “wet”?
Then anti-VEGF injections usually stabilize or improve vision by stopping leak/bleed.Lippincott JournalsWill ENCELTO improve my vision?
It’s designed to slow further damage, not to restore lost photoreceptors. Trials showed slower EZ loss and related functional preservation vs. sham.U.S. Food and Drug AdministrationWhat are ENCELTO risks I should understand?
Surgery/device risks: infection, retinal tear/detachment, vitreous hemorrhage, implant/suture issues, and delayed dark adaptation; your team will review the label and after-care.U.S. Food and Drug AdministrationDo supplements help?
There’s no proven supplement for MacTel. Serine ± fenofibrate is under study; carotenoids don’t fix the MacTel pigment problem and high-dose zeaxanthin has had side effects in a report.ClinicalTrialsPubMedIs MacTel genetic?
There’s a genetic component (for example PHGDH variants), but it’s complex and not simply inherited in most families.PubMedWhy do straight lines look bent?
Because paracentral photoreceptors and supporting structures are thinning, so the image map is distorted.Why can my eye chart look okay, but reading is hard?
Eye charts measure single high-contrast letters; MacTel often hits reading speed, contrast, and fixation first.Can glasses fix it?
Glasses correct focus, not damaged photoreceptors. But magnification and lighting can help a lot.How often should I follow up?
Typical is every 3–12 months depending on stage; sooner if symptoms change.Can I exercise?
Yes—regular, safe exercise supports metabolic health (great for eyes and whole body).What research is most exciting?
Neuroprotection with ENCELTO is already here; metabolic therapy (serine ± fenofibrate) is being tested to lower toxic lipids.U.S. Food and Drug AdministrationClinicalTrials
