Insights

Ocular abnormalities are common in children with fetal alcohol syndrome (FAS). Retinal fundus anomalies and small optic discs were frequently observed, highlighting the importance of ophthalmologic screening in FAS patients.

Area of Science:

  • Ophthalmology
  • Pediatrics
  • Genetics

Background:

  • Fetal Alcohol Syndrome (FAS) is a leading cause of preventable birth defects.
  • Ocular abnormalities are frequently associated with FAS, impacting visual development.
  • Early identification and management of ocular issues in FAS are crucial for improving patient outcomes.

Purpose of the Study:

  • To determine the prevalence of ocular abnormalities in Portuguese children diagnosed with complete Fetal Alcohol Syndrome (FAS).
  • To characterize the spectrum of ocular findings in this specific pediatric population.
  • To contribute data on the ophthalmologic manifestations of FAS.

Main Methods:

  • A comprehensive ophthalmologic examination was performed on a consecutive sample of children with FAS.
  • Ocular fundus photography was utilized for detailed retinal and optic disc assessment.
  • Measurements such as the distance from optic disc center to fovea relative to optic disc diameter (DM/DD) were analyzed to identify small optic discs.

Main Results:

  • The study included 32 children with FAS (mean age 9 years; 72% boys).
  • Common ocular findings included short palpebral fissures (81%), strabismus (28%), epicanthus (27%), and blepharoptosis (16%).
  • Retinal vessel tortuosity (30%) and optic disc hypoplasia (25%) were noted, with 40% of eyes exhibiting small optic discs (DM/DD ratio).

Conclusions:

  • Anomalies of the retinal fundus and external eye structures are the most prevalent ocular findings in children with FAS.
  • The observed visual acuity and disease severity were better than in some previous studies, potentially due to patient selection, alcohol consumption patterns, or genetic factors.
  • Regular ophthalmologic evaluations are essential for children with FAS to detect and manage associated visual impairments.

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...

Diabetic Retinopathy

DefinitionDiabetic retinopathy is a microvascular complication of diabetes affecting the retinal blood vessels.Risk FactorsDiabetic retinopathy is present in almost all individuals with type 1 diabetes and more than 60% of those with type 2 diabetes after two decades of disease.The risk increases with poor glycemic control, hypertension, dyslipidemia, smoking, pregnancy, and puberty.Although cataracts and glaucoma are also more frequent in people with diabetes, retinopathy remains the leading...

Photoreceptors and Visual Pathways

At the molecular level, visual signals trigger transformations in photopigment molecules, resulting in changes in the photoreceptor cell's membrane potential. The photon's energy level is denoted by its wavelength, with each specific wavelength of visible light associated with a distinct color. The spectral range of visible light, classified as electromagnetic radiation, spans from 380 to 720 nm. Electromagnetic radiation wavelengths exceeding 720 nm fall under the infrared category, whereas...
