Central corneal thickness
Ultrasound or optical pachymetry records CCT in microns.

Service Overview
Pachymetry measures how thick the centre of your cornea is. A thick cornea can make eye pressure look higher than it is; a thin cornea can hide dangerous pressure. Gonio pachymetry in our glaucoma service pairs that thickness reading with the angle assessment you need for open- versus closed-angle disease. Together they stop treatment decisions being based on a raw pressure number alone.
What It Covers
Pressure correction context
Helps judge whether Goldmann IOP is over- or under-estimated.
Angle work-up pairing
Used alongside gonioscopy to classify open-angle vs angle-closure risk.
Baseline for years of care
A one-time thickness map still guides every later pressure check.
Who It Is For
New glaucoma suspects
Anyone with high or borderline pressure who needs a proper first work-up.
Thin-cornea or LASIK history
Post-LASIK and keratoconus eyes often read pressure inaccurately without CCT.
Angle-closure risk
Patients who also need gonio assessment of a narrow drainage angle.
How It Works
Numbing drop if needed
Contact pachymetry uses a brief anaesthetic drop; optical methods may not.
Thickness reading
A small probe or light scan measures the cornea at the centre.
Interpret with pressure
Your glaucoma clinician reads CCT with IOP, disc, field, and OCT.
Why Choose Gonio Pachymetry Here
Thickness, gonioscopy, field, and OCT are available in one glaucoma pathway at Darya Ganj, so a suspect is not sent out for a single measurement and then lost to follow-up.
Frequently Asked Questions
Is pachymetry the same as gonioscopy?
No. Pachymetry measures corneal thickness. Gonioscopy looks at the drainage angle inside the eye. We often do both in a glaucoma visit.
Does it hurt?
A numbing drop makes contact pachymetry comfortable. You may feel a light touch lasting a few seconds.
Do I need it every visit?
Usually once as a baseline, then only if the cornea changes (surgery, swelling, or ectasia).
