Insights
Foveal width, measured by optical coherence tomography, is a key indicator for retinopathy of prematurity screening. This finding may aid in managing preterm infants and assessing their visual development.
Area of Science:
- Ophthalmology
- Neonatology
- Medical Imaging
Background:
- Retinopathy of prematurity (ROP) is a leading cause of visual impairment in preterm infants.
- Early detection and monitoring of ROP are crucial for effective management.
- Hand-held optical coherence tomography (OCT) offers a non-invasive method for visualizing retinal structures.
Purpose of the Study:
- To investigate dynamic foveal morphology in preterm infants with and without ROP.
- To assess the relationship between foveal morphology, postmenstrual age, gestational age (GA), and birthweight (BW).
- To evaluate the utility of hand-held OCT in characterizing foveal development in relation to ROP.
Main Methods:
- Prospective observational study of 87 preterm infants (23-36 weeks GA).
- Hand-held OCT imaging used to measure foveal width, area, depth, central foveal thickness, slope, and parafoveal retinal thickness.
- Data analyzed adjusting for GA and BW.
Main Results:
- Foveal width showed a significant correlation with ROP, independent of GA and BW.
- Foveal area, depth, and slope correlated with prematurity severity (GA, BW).
- Central foveal thickness and parafoveal retinal thickness correlated with GA but not BW.
Conclusions:
- Foveal width is a potential biomarker for ROP screening using hand-held OCT.
- Foveal morphology assessment during development may inform future management strategies for preterm infants.
- Dynamic foveal changes can be monitored non-invasively in preterm infants.
Purpose:
To investigate dynamic foveal morphology with postmenstrual age, in preterm infants with and without retinopathy of prematurity using hand-held optical coherence tomography, adjusting for gestational age (GA) and birthweight (BW).
Methods:
Prospective mixed cross-sectional/longitudinal observational study of 87 participants (23-36 weeks GA; n = 30 with, n = 57 without retinopathy of prematurity) using hand-held optical coherence tomography images (n = 278) acquired between 31 weeks and 44 weeks postmenstrual age excluding treated retinopathy of prematurity. Measurements included foveal width, area, depth, central foveal thickness, maximum slope, and parafoveal retinal thickness at 1,000 µm nasal and temporal to the central fovea.
Results:
Retinopathy of prematurity was significantly correlated with only foveal width in either GA or BW adjusted statistical models. In contrast, severity of prematurity (GA, BW) correlated with foveal area (P < 0.005), depth (P ≤ 0.001), and slope (P < 0.01), although central foveal thickness (P = 0.007) and parafoveal retinal thickness (P < 0.001) correlated with GA, but not with BW.
Conclusion:
Foveal width is independent of GA and BW with potential in retinopathy of prematurity screening assessment using hand-held optical coherence tomography. Foveal morphology could be graded in prematurity during development, with possible implications for future management of preterm infants.

Cell Potential and Free Energy
Thermodynamics is the branch of physics dealing with the relationship between heat and other forms of energy. In an electrochemical cell, chemical energy is converted into electrical energy.
Thus, a link can be predicted between cell potential, free energy change, and the equilibrium constant for the reaction. Cell potential can also be measured as the oxidant or the reducing strength, and similar acid-base strength measures are reflected in equilibrium...
