Persistent Hyperplastic Primary Vitreous (PHPV) is a rare condition affecting eye development and vision. Understanding its impact is essential for timely intervention.
Persistent Hyperplastic Primary Vitreous (PHPV), also known as Persistent Fetal Vasculature (PFV), is a rare congenital condition where the blood vessels in the developing eye fail to regress properly before birth. This leftover vascular tissue can interfere with normal eye development and, if not addressed, may result in a range of visual complications. Recognizing and understanding PHPV is essential to ensuring timely care and preserving vision in affected individuals.
During fetal development, a network of blood vessels forms to nourish the growing eye and support its maturation. In a typical scenario, these vessels gradually disappear as the eye develops, making way for the normal structures necessary for good vision. In PHPV, however, some of these vessels persist, potentially interfering with eye development and leading to problems with the lens, retina, or other parts of the eye.
Although PHPV is not usually a hereditary condition, meaning it typically appears without a family history, its presence can profoundly affect vision. In most cases, PHPV affects one eye (unilateral), but on occasion it may involve both eyes. Here’s the important part: while PHPV does not worsen over time, the complications it causes can be significant, making early identification and intervention crucial.
The effect of PHPV on vision depends largely on the extent of the abnormal blood vessels and the parts of the eye that are affected. Some children with PHPV may experience only mild visual issues, while others may have more pronounced impairments. In cases where the condition affects the lens, retinal structure, or overall eye shape, various complications can arise.
Common vision-related issues associated with PHPV include:
These complications emphasize why early diagnosis of PHPV is vital. Even if the condition starts with only subtle symptoms, untreated complications could lead to severe visual impairment later in life.

PHPV is typically identified in infancy, often during routine newborn examinations or when parents notice unusual characteristics in their child’s eyes. Our eye doctors play a critical role in accurately diagnosing this condition, ensuring that appropriate steps are taken early on.
Parents and caregivers might notice signs such as:
During the diagnostic process, our eye doctors usually conduct a thorough dilated eye exam. This detailed examination allows them to observe any abnormal blood vessels or other signs of PHPV. When vision is obstructed by complications such as cataracts, additional imaging tests might be necessary. These can include:
The careful and comprehensive approach to diagnosing PHPV ensures that the underlying causes of visual impairment are detected accurately and quickly.
PHPV results from an interruption in the normal fetal process, where a network of blood vessels that temporarily supply the eye does not vanish as expected before birth. While the precise cause of this failure remains under investigation, most cases are considered sporadic and not linked to genetic inheritance.
In a small number of instances, PHPV may be associated with certain genetic conditions such as Norrie disease or Trisomy 13, yet these situations are rare. The fact that PHPV generally occurs sporadically highlights the unpredictable nature of the condition, reinforcing the need for vigilance during early eye examinations. Here’s a simple breakdown:
This process is delicate, and even minor deviations from the typical developmental course can have lasting impacts. While PHPV itself does not inherently worsen with age, the structural differences it creates can be the basis for further complications if not monitored and managed appropriately.
