Peters anomaly (PA)

Definition and impact on vision

Peters anomaly refers to a condition where the cornea, the transparent layer at the front of the eye, is cloudy and opaque. The severity of the corneal opacity can vary, leading to varying degrees of vision impairment.

In some cases, individuals with Peters anomaly may have near-normal vision, while others may experience significant visual impairment.

Developmental issues and associated conditions

Peters anomaly is typically associated with developmental issues involving the anterior segment of the eye, which includes the cornea, iris, lens, and surrounding structures. Some individuals with Peters anomaly may also develop other eye conditions, such as glaucoma and cataracts.

Additionally, amblyopia (lazy eye), nystagmus (involuntary eye movements), and strabismus (misalignment of the eyes) are commonly observed in individuals with Peters anomaly.

Causes and risk factors

The exact cause of Peters anomaly is not fully understood, but it is believed to involve a combination of genetic factors and environmental influences. Genetic mutations during fetal development may play a role in the development of Peters anomaly.

Various risk factors, such as premature birth, fetal alcohol syndrome, and certain genetic syndromes like Peters plus syndrome and Axenfeld-Rieger syndrome, can increase the likelihood of developing this condition.

Symptoms and diagnosis

Opaque area on the cornea (leukoma)

One of the primary symptoms of Peters anomaly is the presence of a leukoma, an opaque area on the cornea due to the corneal defect. This leukoma can vary in size and location on the cornea.

The degree of opacification determines the visual impairment experienced by the affected individual.

Other ocular symptoms

Apart from the corneal opacity, individuals with Peters anomaly may experience other ocular symptoms. Glaucoma, a condition characterized by increased pressure within the eye, can occur in individuals with Peters anomaly.

Cataracts, a clouding of the eye’s lens, may also develop. Furthermore, amblyopia, nystagmus, and strabismus are commonly observed in individuals with Peters anomaly and can cause additional visual disturbances.

Diagnosing Peters anomaly involves a comprehensive eye examination, including visual acuity testing, corneal evaluation, and imaging techniques such as ultrasound and anterior segment optical coherence tomography (AS-OCT). The presence of a corneal opacity and associated developmental issues help differentiate Peters anomaly from other eye conditions.


By understanding Peters anomaly, we can provide support to affected individuals and raise awareness for this rare condition. Early detection through comprehensive eye examinations is crucial for the proper management of this condition.

With advancements in medical technology and ongoing research, there may be promising treatments on the horizon to improve vision and quality of life for those affected by Peters anomaly.

Treatment options

Multidisciplinary approach and specialists involved

The management of Peters anomaly typically requires a multidisciplinary approach involving various healthcare professionals with expertise in pediatric ophthalmology and corneal diseases. A pediatric ophthalmologist plays a key role in diagnosing and monitoring the condition, while a corneal specialist focuses on managing the corneal opacity.

Additionally, a glaucoma specialist may be involved in cases where glaucoma develops. Collaborating with a low vision optometrist can also be beneficial, as they are trained to help individuals with visual impairments maximize their remaining vision.

Surgical interventions

Surgical intervention is often necessary to manage the corneal opacity in Peters anomaly. Penetrating keratoplasty, also known as corneal transplantation, is the primary surgical option.

During this procedure, the cloudy cornea is replaced with a healthy donor cornea. However, the success of the transplant greatly depends on the severity of corneal involvement and associated developmental issues.

In some cases, additional surgeries, such as cataract extraction, may be performed to optimize visual outcomes.


Complications can arise during and after treatment for Peters anomaly. Graft failure, where the transplanted cornea does not properly integrate with the recipient’s eye, is a possible complication of penetrating keratoplasty.

Close monitoring by the ophthalmologist is necessary to detect signs of graft rejection or failure early on. Infections following surgery are rare but can occur, requiring prompt treatment with antibiotics.

Additionally, the use of long-term topical steroids to prevent graft rejection may lead to steroid-induced glaucoma, a condition characterized by increased pressure within the eye. Regular follow-ups with the glaucoma specialist are crucial to address this potential complication.

Long-term management and outcomes

Amblyopia and visual rehabilitation

Peters anomaly often leads to amblyopia, a condition where the brain relies more on one eye, causing reduced visual acuity in the affected eye. To address amblyopia, visual rehabilitation techniques are necessary.

The primary treatment for amblyopia is patching, where the stronger eye is temporarily covered with an eye patch. This forces the brain to rely on the weaker eye, stimulating its visual development.

The duration and frequency of patching are determined by the ophthalmologist based on the severity of amblyopia. Vision therapy exercises may also be recommended to improve eye muscle coordination and binocular vision.

Working with a low vision specialist

Individuals with Peters anomaly often face long-term visual challenges.

Working with a low vision specialist can significantly improve their functional vision and overall quality of life.

A low vision specialist is trained in assessing visual function and recommending appropriate optical and non-optical aids, such as magnifiers, telescopes, and adaptive technology, to optimize visual tasks. Additionally, they can provide guidance on lighting conditions and environmental modifications to enhance visual accessibility at home, school, and work.

Efforts to manage Peters anomaly are aimed at improving visual outcomes, optimizing development, and promoting independence for individuals with this condition. With appropriate treatment, regular follow-ups, and ongoing support from healthcare professionals, affected individuals can achieve better visual function and lead fulfilling lives.

In summary, the treatment of Peters anomaly involves a multidisciplinary approach encompassing pediatric ophthalmologists, corneal specialists, glaucoma specialists, and low vision optometrists.

Surgical interventions such as penetrating keratoplasty and cataract extraction may be necessary, but complications such as graft failure and infection must be closely monitored.

Long-term management includes addressing amblyopia through visual rehabilitation techniques like patching and collaborating with a low vision specialist to optimize functional vision. By implementing comprehensive treatment strategies and ensuring continued care, individuals with Peters anomaly can overcome visual challenges and thrive.

Early detection and preventive measures

Importance of comprehensive eye exams

Early detection of Peters anomaly is crucial in order to initiate timely interventions and optimize visual outcomes. Comprehensive eye exams play a pivotal role in identifying the condition, even before obvious symptoms manifest.

During a comprehensive eye exam, the ophthalmologist assesses visual acuity, examines the cornea, evaluates the anterior segment of the eye, and checks for any signs of associated developmental issues. This thorough examination allows for the identification of Peters anomaly and the prompt initiation of treatment.

It is essential to prioritize comprehensive eye exams, especially in infants and children at risk of Peters anomaly. Regular eye screenings should begin as early as possible, ensuring that any signs of corneal opacity or developmental abnormalities are detected without delay.

By detecting Peters anomaly early on, healthcare professionals can intervene and implement appropriate treatments to minimize the impact on visual function and overall development.

Family history and pre-birth planning

Family history plays a significant role in determining the likelihood of developing Peters anomaly. If there is a known history of Peters anomaly or other eye conditions within the family, it is important to inform the healthcare provider during pre-birth planning and prenatal care.

Such information enables the healthcare team to closely monitor the developing fetus and implement preventive measures when necessary. During pre-birth planning, genetic counseling may be recommended for couples with a family history of Peters anomaly.

Genetic counseling provides valuable information about the inheritance pattern and associated risks. It can help parents make informed decisions regarding family planning and offer guidance on preventive measures that may be available.

In cases where a genetic syndrome, such as Peters plus syndrome or Axenfeld-Rieger syndrome, is known to be associated with Peters anomaly, genetic testing may be suggested. Genetic testing can help identify specific mutations and provide more precise information about the risks of Peters anomaly in future pregnancies.

Additionally, avoiding exposure to known risk factors during pregnancy, such as alcohol consumption, can contribute to prevention efforts. Fetal alcohol syndrome has been associated with an increased risk of Peters anomaly, emphasizing the importance of abstaining from alcohol during pregnancy.

By understanding the significance of family history and engaging in pre-birth planning, parents can take proactive steps towards early detection and prevention of Peters anomaly. This collaborative approach between healthcare providers and families promotes the well-being of the child and empowers them with the knowledge needed to make informed decisions.


Early detection of Peters anomaly through comprehensive eye exams and pre-birth planning is vital for optimal management and visual outcomes. Regular screenings enable healthcare providers to identify the condition promptly and initiate appropriate interventions.

Family history and genetic counseling play important roles in understanding the risks associated with Peters anomaly, enabling families to make informed decisions and take preventive measures. By emphasizing the importance of early detection and preventive measures, we can contribute to the overall well-being and development of individuals with Peters anomaly.

In conclusion, understanding Peters anomaly is vital for early detection and effective management. Through comprehensive eye exams, healthcare professionals can identify the condition early on, allowing for prompt intervention and improved visual outcomes.

Collaborating with specialists, such as corneal and glaucoma specialists, ensures comprehensive care. Pre-birth planning and genetic counseling help families take preventive measures and make informed decisions.

By prioritizing early detection and preventive measures, we can significantly impact the lives of individuals with Peters anomaly, empowering them to thrive and promoting a brighter future for all.
