Correlation of recognition visual acuity with posterior retinal structure in advanced retinopathy of prematurity

Insights

Visual acuity outcomes in infants with retinopathy of prematurity generally align with retinal structure at age 6. However, poor vision with normal retinas may indicate optic atrophy or cortical visual impairment.

Area of Science:

  • Ophthalmology
  • Pediatric Medicine
  • Retinal Imaging

Background:

  • Retinopathy of prematurity (ROP) is a leading cause of childhood blindness.
  • Assessing long-term visual outcomes in ROP is crucial for understanding disease progression and treatment efficacy.

Purpose of the Study:

  • To compare visual acuity outcomes with retinal structural outcomes at 6 years in infants randomized in the Early Treatment for Retinopathy of Prematurity study.
  • To investigate the correlation between functional vision and retinal anatomy in infants with a history of severe ROP.

Main Methods:

  • A cohort of 606 eyes from the Early Treatment for ROP study underwent visual acuity and retinal structural assessments at age 6.
  • Visual acuity was measured by masked testers, and retinal examinations were performed by certified ophthalmologists.

Main Results:

  • Concordant functional and structural outcomes were observed in 76.2% of eyes.
  • Discordant outcomes occurred in 15.2% of eyes, with 86 eyes showing unfavorable vision despite favorable retinal structure.
  • Optic atrophy and less severe retinal abnormalities accounted for discrepancies in eyes with poor vision and normal retinas.

Conclusions:

  • Posterior pole appearance correlates well with visual acuity in 6-year-old infants with a history of advanced ROP.
  • In cases of poor vision with normal retinal structure, clinicians should consider optic atrophy and cortical visual impairment as potential contributing factors.

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...

Anatomy of the Eyeball

The eye is a spherical, hollow structure composed of three tissue layers. The outer layer — the fibrous tunic, comprises the sclera — a white structure — and the cornea, which is transparent. The sclera encompasses some of the ocular surface, most of which is not visible. However, the 'white of the eye' is distinctively visible in humans compared to other species. The cornea, a clear covering at the front of the eye, enables light penetration. The eye's middle layer, the vascular tunic,...

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...
