Insights

Ocular abnormalities are common in glutaric aciduria type 1 (GA1). This rare metabolic disorder can cause various eye issues, including hemorrhages that may be mistaken for child abuse.

Area of Science:

  • Medical Genetics
  • Ophthalmology
  • Pediatrics

Background:

  • Glutaric aciduria type 1 (GA1) is a rare inherited metabolic disorder.
  • It results from deficiency of the enzyme glutaryl-CoA dehydrogenase.
  • GA1 can lead to severe neurological damage and developmental delay.

Purpose of the Study:

  • To investigate the spectrum and progression of ocular abnormalities in children diagnosed with GA1.
  • To highlight the importance of ophthalmologic evaluations in GA1 patients.

Main Methods:

  • Retrospective review of medical records for deceased GA1 patients.
  • Prospective clinical ophthalmologic examinations for surviving GA1 patients.
  • Study conducted on 15 children with GA1 in the Republic of Ireland.

Main Results:

  • Seven out of 15 children (47%) exhibited abnormal eye findings.
  • Documented ocular complications included intraretinal hemorrhages, cataract, gaze palsy, strabismus, ametropia, and pigmentary retinopathy.
  • Intraretinal hemorrhages were a significant finding.

Conclusions:

  • Ocular involvement is a frequent manifestation of GA1.
  • Comprehensive ophthalmologic assessment is crucial for all suspected GA1 cases.
  • GA1-related intraretinal hemorrhages necessitate inclusion in the differential diagnosis of non-accidental head injury (child abuse).

Glucose Transporters01:27

Glucose Transporters

Glucose transporters facilitate the transport of glucose across the cell membrane. In addition to glucose, some glucose transporters can also aid the movement of other hexoses such as fructose, mannose, and galactose.
Facilitated diffusion-glucose transporters (GLUTs) are encoded by the solute-linked carrier (SLC) family 2, subfamily A gene family, or SLC2A. The 14 GLUT protein members are distributed into three classes:
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...
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...
Photoreceptors and Visual Pathways01:22

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...

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...
