Summary
This study used Pentacam imaging to analyze anterior segment parameters in 60 young Indian adults. Findings provide normative data for corneal thickness, volume, and anterior chamber dimensions in this population.
Area of Science:
- Ophthalmology
- Corneal Imaging
- Anterior Segment Analysis
Background:
- Accurate anterior segment parameters are crucial for diagnosing eye conditions and planning surgeries.
- Normative data specific to diverse populations, like young Indian adults, is essential for precise clinical assessments.
Purpose of the Study:
- To evaluate anterior segment parameters using Pentacam-Scheimpflug imaging in healthy young Indian adults.
- To establish normative values for central corneal thickness (CCT), thinnest corneal thickness (TCT), corneal volume (CV), anterior chamber depth (ACD), anterior chamber volume (ACV), and anterior chamber angle (ACA).
Main Methods:
- Prospective study involving 120 eyes of 60 normal Indian subjects (mean age 25.93 ± 6.58 years).
- Anterior segment parameters were measured using Pentacam-Scheimpflug imaging.
- Statistical analysis included independent and dependent samples t-tests, ANOVA, and Pearson correlation.
Main Results:
- Mean CCT: 544.95 ± 35.42 μm, Mean TCT: 542 ± 35.19 μm, Mean CV: 61.64 ± 4.17 μm³.
- Mean ACD: 3.14 ± 0.33 mm, Mean ACV: 177.77 ± 29.02 mm³, Mean ACA: 39.36° ± 5.42°.
- Corneal thickness increased from the thinnest point to the periphery; TCT location varied. No significant gender or eye laterality differences were observed.
Conclusions:
- This study provides comprehensive normative data for anterior segment parameters in young Indian adults.
- These findings are valuable for the clinical assessment of corneal diseases, glaucoma, and screening for refractive surgeries in this demographic.

DefinitionComputed Tomography (CT) of the genitourinary (GU) tract is a non-invasive imaging modality that utilizes X-rays and computer processing to generate detailed cross-sectional images of the urinary system, encompassing the kidneys, ureters, bladder, and adjacent structures such as the adrenal glands.PurposeCT scans of the GU tract serve several diagnostic and therapeutic purposes, including:Diagnosis of Urinary Tract Diseases: Detects kidney stones, tumors, cysts, and congenital...
01:10Computed Tomography
Tomography refers to imaging by sections. Computed tomography (CT) is a non-invasive imaging technique that uses computers to analyze several cross-sectional X-rays to reveal minute details about structures in the body.
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...
