Bergmeister Papilla

Bergmeister papilla is a tiny, benign growth seen on the optic disc of the eye. It represents a remnant of the fibrous sheath that once surrounded the fetal hyaloid artery—a vessel that nourished the developing lens in the womb. During normal eye development, this artery and its sheath regress completely by the time a baby opens its eyes, usually around birth. If the sheath does not fully disappear at the optic disc, it leaves behind a small tuft or veil of fibrous tissue known as the Bergmeister papilla WikipediaEyeWiki.

Bergmeister Papilla derives its name from the 19th-century Austrian ophthalmologist O. Bergmeister, who first described these fibrous tufts. In embryonic development, the hyaloid artery nourishes the developing lens and vitreous. By around the seventh month of gestation, this artery typically regresses completely. In some individuals, small portions remain adherent to the optic disc as glial tissue—visible as Bergmeister’s papilla. Clinically, it appears as a fine, thread-like opacity extending into the vitreous cavity. While most cases are incidental findings without vision loss, large or vascularized remnants can cause tractional retinal detachment or hemorrhage, especially if the fibrous band exerts pull on adjacent retina.

Clinically, Bergmeister papilla appears as a grayish or whitish plume arising centrally on the optic nerve head. It is often discovered by chance during routine eye exams, as most people with this finding have no vision problems directly caused by it. The papilla is typically avascular (lacking blood vessels), though in rare cases a tiny vessel may persist within it, which can be seen on fluorescein angiography EyeWikioptos.com.

Because it is a leftover of normal fetal anatomy, Bergmeister papilla is considered a congenital anomaly rather than a disease. It does not usually change over a person’s lifetime and, unless complicated by other eye conditions, does not require treatment.

Types

Ophthalmologists categorize Bergmeister papilla into two main morphological types based on how the fibrous tissue relates to the optic disc surface Nature:

1. Lifting-Edge Type
   In this form, the remnant tissue emerges from the margin of the optic disc and lifts slightly above the surrounding nerve tissue. On optical coherence tomography (OCT), it appears as a discrete ridge or “lip” at the edge of the disc. This lifting-edge configuration may subtly alter measurements of disc parameters—such as cup depth—by creating an artificial mound along the rim Nature.

2. Covering-Disc Type
   Here, the fibrous sheath remnant spreads across and partially covers the optic disc, forming a cap or veil. On fundus photography, it looks like a semitranslucent membrane draped over the disc center. OCT imaging shows a sheet of hyperreflective tissue extending over the cup region. This covering-disc variant can more significantly affect quantitative OCT metrics of the nerve head and nerve fiber layer if not recognized Nature.

Although rare, some eyes may display features of both types, with a central covering membrane plus raised edges. Both forms are benign and incidentally detected, but correctly identifying the type helps clinicians avoid misinterpreting OCT or disc photographs, especially when monitoring for glaucoma.

Causes

The sole underlying cause of Bergmeister papilla is incomplete regression of the hyaloid artery’s fibrous sheath at the optic disc during fetal eye development. However, researchers believe several genetic and environmental factors influence this failure of regression. While much remains under study, the following 15 factors have been associated with persistent fetal vascular remnants such as Bergmeister papilla:

1. Failure of Programmed Involution
   A breakdown in the normal process of vessel involution causes remnants to persist. The hyaloid system should regress between 20 and 30 weeks of gestation, but when apoptosis signals are disrupted, tissue remains Radiopaedia.

2. Defective Apoptosis-Related Genes
   Mutations or dysregulation of genes that control endothelial cell apoptosis—such as p53—can hinder vascular pruning, leaving remnants on the disc EyeWiki.

3. Wnt7b Pathway Abnormalities
   Loss of Wnt7b signaling in hyalocytes (vitreous‐resident macrophages) impairs the normal clearance of fetal vessels, contributing to persistence of the papilla EyeWiki.

4. Angiopoietin-2 (Ang2) Imbalance
   Ang2 helps regulate vessel stability and regression. Abnormal Ang2 levels can tip the balance toward persistence rather than involution EyeWiki.

5. VEGF Dysregulation
   Overexpression of vascular endothelial growth factor (VEGF) may promote unwanted survival of fetal vessels and their sheaths EyeWiki.

6. Absence of the Arf Tumor Suppressor
   The Arf protein normally supports vessel regression; its absence in experimental models leads to persistent fetal vasculature EyeWiki.

7. Prematurity
   Babies born before 37 weeks often have higher rates of hyaloid remnants. Traditional ophthalmoscopy shows up to 95% prevalence in premature infants Nature.

8. Low Birth Weight
   Infants with low birth weight may not complete normal vasculature regression in utero, increasing persistence risk Nature.

9. Genetic Syndromes (e.g., Norrie Disease)
   Certain inherited conditions affecting retinal vascular development often include persistent fetal vasculature features AAO.

10. Chromosomal Anomalies (Trisomy 13, 18)
    These syndromes frequently show ocular malformations, including persistent hyaloid remnants Nature.

11. Intrauterine Hypoxia
    Oxygen deprivation in the womb may alter normal vessel regression signals, leading to remnants.

12. Maternal Diabetes
    High maternal blood sugar can disrupt fetal vascular development, sometimes causing incomplete vessel involution.

13. Intrauterine Infection
    Infections such as rubella or toxoplasmosis during pregnancy may affect eye development and vascular regression.

14. Nutritional Deficiencies
    Lack of key nutrients (e.g., vitamin A) could impair normal apoptosis of fetal vessels.

15. Twin or Multiple Pregnancy
    Altered intrauterine environment in multiples may affect timing of vessel regression, leaving remnants.

While Bergmeister papilla itself carries no direct health risks, these factors often overlap with more extensive persistent fetal vasculature (PFV) syndromes, which can cause vision‐threatening complications.

Symptoms

Most individuals with a Bergmeister papilla experience no symptoms. It is almost always an incidental finding during routine eye exams. When symptoms do occur, they usually reflect associated or more extensive vascular remnants rather than the papilla alone. Ten possible presentations include:

1. Asymptomatic Presentation
   The vast majority have perfect vision and no complaints; the papilla is found only upon dilated fundus exam EyeWiki.

2. Visual Floaters
   Occasional tiny fibers may cast shadows on the retina, perceived as floaters.

3. Mild Blurring of Vision
   In rare cases, a larger covering‐disc type may slightly distort central vision.

4. Visual Field Defects
   If the remnant affects nerve fiber arrangement, subtle blind spots may appear on formal perimetry.

5. Leukocoria
   A white pupillary reflex in infants might lead to detection—though more often indicates PFV or other conditions.

6. Strabismus (Eye Misalignment)
   Associated PFV can cause axial length changes, leading to misalignment in some eyes.

7. Microphthalmos
   Smaller‐than‐normal eye size when PFV is more extensive.

8. Nystagmus
   In severe PFV, infants may develop involuntary eye movements.

9. Early Cataract Formation
   Persistent anterior vasculature can leave pupillary membrane remnants over the lens [leading to cataract].

10. Vitreous Hemorrhage
    Abnormal vessels in PFV may bleed into the vitreous, though pure Bergmeister papilla rarely bleeds.

Because true Bergmeister papilla is benign and quiescent, most people never notice symptoms attributable solely to it. Any vision change warrants evaluation for broader PFV involvement or other eye disease.

Diagnostic Tests

Accurate recognition of Bergmeister papilla relies on a combination of simple clinical assessments and advanced imaging. Below are 20 diagnostic approaches, grouped by category, each explained in simple terms.

Physical Exam

1. Visual Acuity Testing
   Measures how clearly you see letters or symbols at distance. Helps detect any loss of sharpness that might suggest complications EyeWiki.

2. Red Reflex Examination
   Shining light into the pupil should reveal a red glow; a white reflex (leukocoria) prompts further investigation for PFV or papilla.

3. Pupillary Light Reflex
   Observing the pupil’s response to light checks nerve function and rules out optic nerve pathology.

4. External Eye Inspection
   Examining lids, lashes, and cornea for any visible anomalies associated with broader congenital syndromes.

5. Intraocular Pressure Measurement
   Tonometry ensures that pressure is normal, as PFV can sometimes raise eye pressure.

Manual Tests

6. Slit-Lamp Examination
   Using a microscope and bright light to view the front and back parts of the eye in detail, spotting any fibrous veils near the disc EyeWiki.

7. Direct Ophthalmoscopy
   A handheld scope on the clinician’s head lets them look directly at the optic disc, where the papilla appears as a small tuft.

8. Indirect Ophthalmoscopy
   Using a head‐mounted light and a handheld lens to get a wider view of the retina, often after pupil dilation.

9. Confrontation Visual Field Test
   The examiner compares your peripheral vision to theirs, detecting any field loss.

Lab and Pathological Tests

10. Genetic Testing
    Screening for mutations in genes like NDP (Norrie), p53, or Wnt pathway genes if PFV syndromes are suspected AAO.

11. Metabolic Screening
    Blood tests for inborn errors that sometimes co-occur with ocular developmental anomalies.

12. Histopathology of Vitreous Sample
    Rarely done; microscopic study of removed vitreous tissue confirms fibrous glial composition.

13. PCR for Intrauterine Infection
    In infants, testing ocular fluid for viral or bacterial DNA if congenital infection is suspected.

Electrodiagnostic Tests

14. Electroretinogram (ERG)
    Measures electrical response of the retina to light, ensuring overall retinal health Radiopaedia.

15. Visual Evoked Potential (VEP)
    Tracks nerve signals from the eye to the brain, checking optic nerve integrity.

16. Electrooculogram (EOG)
    Assesses function of the retinal pigment epithelium and photoreceptors.

Imaging Tests

17. Optical Coherence Tomography (OCT)
    High-resolution cross-sectional images of the optic nerve head reveal the shape and thickness of residual tissue EyeWikiNature.

18. Fundus Photography
    Color photos of the back of the eye document the papilla’s appearance and track changes over time.

19. Fluorescein Angiography (FA)
    Dye injected into the arm lights up blood vessels in the eye; confirms whether any vessel runs through the papilla.

20. B-Scan Ultrasound
    Sound waves produce images of the eye’s interior, useful if cataract or opacity blocks direct view.

Each of these tests contributes to a complete picture of the optic disc and surrounding structures. In most cases of isolated Bergmeister papilla, only ophthalmoscopy and OCT are needed for a confident diagnosis.
