Couldn't load pickup availability
Schiotz indentation tonometer, the essential portable IOP measurement device for glaucoma screening in settings where slit-lamp-mounted Goldmann applanation tonometry isn't available. Complete original set: tonometer body, plunger and 3 weights (5.5g, 7.5g, 10g), IOP conversion table and blue deluxe case with velvet inserts. High-quality agate bearing for extremely long service life. Precision measurement on 0-20 subdivision scale (with 0 to -1 sub-divisions for over-range readings). Perfect scale reading via red pointer. All vital parts stainless steel, other parts chrome-plated. $199 direct.
Complete Kit Contents
- Schiotz tonometer body (stainless steel and chrome-plated)
- Precision plunger (agate bearing)
- 3 weights: 5.5g (low IOP), 7.5g (medium IOP), 10g (high IOP)
- Scale-to-IOP conversion table (converts subdivision reading and weight to mmHg)
- Blue deluxe case with velvet-look inserts
- User manual and IFU
Applications
- Glaucoma screening: primary care and community screening where Goldmann applanation isn't available
- Emergency and urgent care IOP: acute angle-closure glaucoma diagnosis and red-eye workup
- Rural and underserved clinical settings: no slit lamp / no Goldmann
- Bedside IOP in supine patients: hospital, nursing home and ICU (Schiotz is one of few options that works supine)
- Post-operative IOP monitoring: post-cataract, post-glaucoma surgery IOP check
- Veterinary ophthalmology: canine, feline, equine and large animal IOP measurement
- NGO glaucoma outreach: cataract and vision camps needing portable IOP
- Optometry and ophthalmology teaching: historical and practical demonstration of indentation vs applanation tonometry
How Schiotz Differs from Goldmann Applanation
- Goldmann applanation (slit lamp mounted): gold standard for accuracy in seated adult patients. Requires topical anesthetic, fluorescein and slit lamp. Not portable.
- Schiotz indentation (this): portable, works supine, no slit lamp needed. Requires topical anesthetic. Reading depends on corneal thickness and rigidity (less accurate in very high/low IOP and post-refractive surgery corneas). Sufficient for screening and supine patients.
- iCare rebound tonometer (electronic): most portable and no anesthetic needed. Higher cost ($1,500-$3,000 vs $199 Schiotz). Better for high-volume screening and pediatric.

FAQ
How does this compare to Riester / Heine Schiotz tonometers?
Feature parity, agate bearing, 3 weights, stainless and chrome components, conversion table. Riester, Heine have slightly higher polish and longer warranty. Price differential: $199 vs $400-$700 for Riester/Heine. Same clinical measurement, same conversion table math.
How accurate is Schiotz vs Goldmann?
Schiotz has ±3-5 mmHg accuracy vs Goldmann's ±1 mmHg gold standard. Sufficient for glaucoma SCREENING, supine patients and emergency. For definitive glaucoma diagnosis and management, Goldmann is preferred where available.
Do I need topical anesthetic?
Yes, proparacaine or tetracaine drops for corneal anesthesia before Schiotz measurement. Patient supine, eye anesthetized, tonometer placed vertically on cornea, weight applied, scale read.
Which weight do I use?
Start with 5.5g (default). If reading is too high on scale (indicating high IOP), add the 7.5g. If still too high, add the 10g. Convert scale reading and weight to mmHg via the supplied table. Weights are additive: 5.5g alone, or 5.5+7.5=13g, or 5.5+7.5+10=23g.
