Insights

Persistent fetal vasculature (PFV) presents variably and is linked to congenital cataracts. While cataract surgery in PFV patients carries risks, 83% of operated eyes showed improved vision.

Area of Science:

  • Ophthalmology
  • Pediatric Ophthalmology
  • Genetics

Background:

  • Persistent fetal vasculature (PFV) is a congenital eye anomaly resulting from the failure of the primary vitreous to regress.
  • It can lead to significant visual impairment, including congenital cataracts, and requires specialized management.
  • Understanding the ocular features and outcomes is crucial for effective patient care.

Purpose of the Study:

  • To delineate the ocular characteristics of persistent fetal vasculature (PFV).
  • To describe the surgical management strategies for congenital cataracts in PFV patients.
  • To evaluate the functional visual outcomes following cataract surgery in this cohort.

Main Methods:

  • A retrospective, descriptive case series was conducted.
  • Data from 46 patients (53 eyes) diagnosed with PFV between 2001 and 2012 were analyzed.
  • Ocular features, systemic findings, surgical interventions, and visual acuities pre- and post-operatively were recorded. Ultrasound and eco-Doppler were utilized.

Main Results:

  • The study included 53 eyes with PFV, with a mean age at diagnosis of 22.7 months. Combined anterior and posterior forms were most common (79.2%).
  • Cataract surgery was performed on 38 eyes, with lensectomy and vitrectomy (47.4%) or phacoaspiration (39.5%) being primary methods.
  • Postoperative complications occurred in 50% of operated eyes, yet 83% achieved improved visual acuity.

Conclusions:

  • Persistent fetal vasculature exhibits diverse clinical presentations and is associated with congenital cataracts.
  • Cataract surgery in PFV patients is linked to severe complications but offers significant visual improvement in the majority of cases.
  • This highlights the importance of careful surgical planning and management for favorable visual outcomes.

Glaucoma: Overview01:25

Glaucoma: Overview

Glaucoma is an eye condition characterized by increased intraocular pressure that damages the retina and optic nerve, leading to irreversible blindness if left untreated. The human eye has various components, including the cornea, iris, pupil, lens, and optic nerve. Aqueous humor is secreted by the epithelium of the ciliary body in the posterior chamber and flows through the trabecular meshwork and canal of Schlemm, maintaining normal intraocular pressure. The trabecular meshwork and the canal...
Fetal Circulation01:14

Fetal Circulation

Fetal circulation is a unique system that facilitates the exchange of gases, nutrients, and waste products between the developing fetus and the mother. This intricate process takes place through a special organ called the placenta.
Two umbilical arteries transport blood from the fetus to the placenta. At the placenta, the blood absorbs oxygen and nutrients while simultaneously eliminating waste products. This oxygen-enriched and nutrient-rich blood then returns to the fetus through one...
Open Angle Glaucoma: Treatment01:27

Open Angle Glaucoma: Treatment

In open-angle glaucoma, the iridocorneal angle remains open, but the trabecular meshwork becomes stiff, slowing down the outflow of aqueous humor. This causes a buildup of aqueous humor in the anterior chamber, leading to a sudden increase in intraocular pressure. The treatment for open-angle glaucoma focuses on reducing the elevated intraocular pressure by either decreasing the secretion of aqueous humor or increasing its outflow.
Drugs such as carbonic anhydrase inhibitors, α2- and...
Angle Closure Glaucoma: Treatment01:28

Angle Closure Glaucoma: Treatment

Angle-closure glaucoma, or closed-angle glaucoma, is an eye condition where the iris bulges out and blocks the iridocorneal angle, resulting in a buildup of aqueous humor and increased intraocular pressure. Immediate medical attention is necessary due to the sudden onset of symptoms. The treatment for angle-closure glaucoma includes short-term and long-term approaches. Short-term treatment involves using eye drops like pilocarpine to lower intraocular pressure by increasing aqueous humor...
