Anterior segment mesenchymal dysgenesis (ASD) is a group of birth-present (congenital) conditions where the front part of the eye does not form normally in the womb. The “anterior segment” includes the cornea, iris, pupil, anterior chamber/angle, ciliary body, and lens. In ASD, one or more of these structures are abnormal because the embryonic neural crest–derived mesenchyme that helps build them did not migrate, separate, or mature as it should. ASD is an umbrella term that includes patterns like Axenfeld–Rieger spectrum and Peters anomaly. These conditions can lower vision from corneal haze, abnormal pupil shape, or glaucoma, and they may appear in one or both eyes. Genetic Diseases Center+2AAO+2
ASD is often genetic. The most frequently involved genes are FOXC1 and PITX2 (common in Axenfeld–Rieger), while PAX6, CYP1B1, and others can be seen in some cases, especially with Peters anomaly or overlapping malformations. Inheritance may be autosomal dominant or rarely recessive, and the same variant can look different in different people (variable expressivity and penetrance). Because different genes interact during eye development, gene “dose” (how much functional protein is made) matters, and small changes can lead to a wide range of features. PMC+3PubMed+3PMC+3
A major lifelong concern in ASD is glaucoma (high eye pressure that can damage the optic nerve). The risk varies by subtype but is substantial in many patients, particularly those with Peters anomaly or prominent angle abnormalities; corneal opacity and systemic anomalies are also common in Peters anomaly. Early diagnosis and regular follow-up are essential to protect vision. MDPI+2PMC+2
ASD means the front of the eye did not grow in the usual way before birth. The clear window of the eye (cornea), the colored part (iris), the drainage angle, and sometimes the lens can be formed in the wrong shape, in the wrong place, or stuck together. Because of this, the eye may be cloudy, the pupil may look different, and the fluid may not drain well, causing high pressure (glaucoma). ASD often happens because of small changes in important growth genes that guide eye building. Doctors diagnose it by eye exam and imaging, sometimes with genetic testing, and then manage vision, treat glaucoma, and decide if surgery can safely help. AAO+1
Anterior segment mesenchymal dysgenesis (ASMD) is a group of birth-time eye conditions where the front parts of the eye—especially the cornea (clear window), iris (colored part), lens, drainage angle, and ciliary body—do not form in the usual way while the baby is developing in the womb. Because these tissues grow abnormally, the eye’s front structures may be shaped differently, stuck together, or partly missing. These changes can blur vision, make the cornea cloudy, and often raise the risk of glaucoma (high pressure in the eye that can damage the optic nerve). Doctors call this whole group anterior segment dysgenesis because it is a developmental (“dys-genesis”) problem of the front (“anterior segment”) of the eye. Nature+1
Other names
Anterior segment dysgenesis (ASD)
Anterior segment mesenchymal dysgenesis (ASMD) (older term; “mesenchymal” refers to early supporting tissue during development)
Anterior chamber cleavage syndromes (historic umbrella term)
Primary mesodermal dysgenesis of the cornea (historic; often used in Peters anomaly context)
Axenfeld anomaly / Rieger anomaly / Axenfeld–Rieger syndrome (ARS) (named subtypes in the spectrum)
Peters anomaly / Peters plus syndrome (a specific subtype with central corneal opacity)
These names reflect different patterns within the same developmental family. ScienceDirect+2EyeWiki+2
During early pregnancy, special control genes tell eye tissues how to form and separate. In ASMD, some of these genes—especially FOXC1, PITX2, PAX6, PITX3, FOXE3, CYP1B1, SOX2, COL4A1/2, and others—can be changed (mutated). When this happens, the cornea, iris, and drainage tissues may not separate correctly, leaving strands or adhesions and a crowded drainage angle. That’s why glaucoma occurs in many patients (often around half), either in infancy or later childhood/teen years. PMC+2NCBI+2
Types
Think of ASMD as a family with several members. A person may have one of these or features that overlap more than one.
Axenfeld anomaly
Posterior embryotoxon (a prominent white ring at the edge of the cornea) plus thin iris strands that attach to the cornea’s edge. Drainage angle may be abnormal. May be silent or lead to glaucoma later. NCBIRieger anomaly
All Axenfeld features plus iris under-development (holes, corectopia—off-center pupil). Greater risk of glaucoma because the angle is more malformed. NCBIAxenfeld–Rieger syndrome (ARS)
Rieger anomaly plus body (systemic) features, such as dental changes (small or missing teeth), facial bone differences, and umbilical issues. About half develop glaucoma; onset can be infancy through adolescence. Often linked to FOXC1 or PITX2 variants. NCBI+2MedlinePlus+2Peters anomaly
Central corneal opacity (a white spot in the center) with loss of the inner corneal layers and sometimes adhesions from iris or lens to the cornea. Vision may be poor at birth. Peters plus syndrome adds body features and is linked to B3GALTL variants. NCBI+2PMC+2Aniridia (partial or variant forms)
Under-development of the iris; classic aniridia is often due to PAX6, but FOXC1/PITX2 can contribute to partial aniridia patterns within the ASD spectrum. Taylor & Francis OnlineSclerocornea / posterior keratoconus / other corneal dysgeneses
Cornea may be opaque (white) at the edge or shaped differently at the back surface. These changes can overlap with ASD features. ScienceDirect

Some cases have no identified gene; subtle multi-gene and environmental influences during embryogenesis likely contribute. PMCEmbryologic failure of tissue separation
When cornea, iris, and lens fail to separate fully, bands/adhesions remain, distorting the angle and pupil. This mechanism underlies many ASD patterns. NatureAbnormal neural crest cell migration
Much of the anterior segment originates from neural crest cells; if they migrate or mature abnormally, ASD results. NatureReduced development of the trabecular meshwork/Schlemm canal
Leads to poor fluid drainage and glaucoma risk. NCBISyndromic associations beyond ARS/PPS

Surgeries
1) Glaucoma surgery (trabeculotomy/goniotomy; trabeculectomy; drainage device)
Procedure: Angle surgeries (goniotomy/trabeculotomy) open the eye’s drainage channels; if insufficient, trabeculectomy or glaucoma drainage implants create a new outflow path. Why: Lower IOP when drops are not enough to protect the optic nerve in ASD. Notes: Outcomes and choices vary with age and angle anatomy; antifibrotics may be used cautiously. PMC
2) Penetrating keratoplasty (full-thickness corneal transplant)
Procedure: Replace cloudy central cornea with donor tissue in suitable eyes. Why: Improve clarity and enable vision development in Peters anomaly with central opacity. Notes: Pediatric grafts are challenging; amblyopia therapy and glaucoma control are crucial for visual success. MDPI
3) Optical iridectomy (selected cases)
Procedure: Create a new opening in the peripheral iris to improve a visual axis when central opacity blocks the pupil. Why: Provide a clear optical path without immediate graft. Notes: Works best in limited, specific patterns. AAO
4) Lensectomy/cataract extraction (if lens adheres or is opaque)
Procedure: Remove an abnormal or adherent lens (as in Peters with lenticulo-corneal touch) if it blocks vision or causes inflammation. Why: Clear the visual axis and reduce complications. Notes: Aphakia correction with contact lens or secondary IOL is planned case-by-case. PMC
5) Combined staged procedures (cornea + glaucoma)
Procedure: Sometimes corneal surgery and glaucoma procedures are combined or staged to balance clarity and pressure control. Why: Reduce multiple anesthetics and coordinate care in complex eyes. Notes: Multidisciplinary pediatric teams plan the sequence. Taylor & Francis Online

What to eat and what to avoid
What to eat: Balanced diet with fruits/vegetables (antioxidants), whole grains, lean proteins, and omega-3–rich foods (fish, flax, chia) to support general and ocular surface health; adequate hydration for a healthy tear film. AAO
What to avoid: Megadose supplements or herbal products in children without medical guidance; smoke exposure and excess UV (use hats and UV-blocking glasses); rubbing the eyes, especially after surgery or with fragile corneas. Nutrition cannot “fix” ASD but supports healing and comfort. MDPI
Frequently asked questions
1) Is ASD one disease or many?
It’s a group of conditions that look different but share a common cause: early developmental problems in the front of the eye. AAO
2) What genes are most common?
FOXC1 and PITX2 in Axenfeld–Rieger; PAX6, CYP1B1, and others in some cases. MedlinePlus+1
3) Will my child definitely get glaucoma?
No, but risk is high in many ASD types, so regular pressure checks are essential. Taylor & Francis Online
4) Can glasses fix ASD?
Glasses improve focus and help prevent amblyopia, but they do not correct the underlying anatomy. AAO
5) Is surgery always needed?
No. Many children are managed with glasses, patching, and drops. Surgery is used for vision-blocking corneal opacity or uncontrolled glaucoma. MDPI+1
6) Are corneal transplants successful in children?
They can help, but pediatric grafts are challenging, and success depends on amblyopia therapy and IOP control. MDPI
7) Can ASD affect other parts of the body?
Yes, especially in Axenfeld–Rieger syndrome, which may include tooth and facial features. A genetics consult helps. EyeWiki
8) Will both eyes be affected?
