Accuracy of Transpalpebral Tonometer Compared to Goldmann Applanation Tonometer in Normal and Glaucomatous Eyes.

 

M.A. Latina, T.A. Shazly, R. Iospa, E.W. Chynn

 

The Diaton, a transpalpebral measurement device, which avoids corneal contact, correlates within 3 mmHg of Goldmann applanation tonometry in 83,3% of eyes in this limited study. Diaton Tonometer may be a clinically useful screening device for measuring IOP.

 

 

Pen-like, hand-held, portable device is perfect for measuring eye pressure during screening examinations of the patients or IOP control during selection of adequate medicines. Diaton tonometer helps ophthalmologists, doctors of general practice and optometrists in diagnosis and prevention of blindness caused by glaucoma.

 

Diaton tonometer is effective and irreplaceable in various situations where any other corneal tonometry methods simply cannot be used. For example, Diaton tonometery approach is ideal for patients with corneal concerns like conjunctivitis, cornea pathology, keratitis, keratocone, keratoplastik, edema, erosion, high degree of ametropy or astigmatism, keratoprosthesis, or acquiring IOP following laser refractive (LASIK, LASEK, PRK) and other corneal surgeries. It is also possible to monitor the IOP in immobilized patients and children.

 

 

Here you will find a scientific reports for clinical use of the Diaton Tonometer in Medical Practice.

Ballistic Principle Diaton Tonomety can be used as an alternative for the measurement of the intraocular pressure above eyelids of patients with recent ocular surgeries, after refractive surgeries, with severe corneal injuries, with corneal apoptosis of epithilium and with large pterygium. Additionally, children can be measured easily with Diaton for IOP and also it can be used in patients with mobility problems.

Transpalpebral Tonometry is an accurate method of IOP measurement that is also independent from the biomechanical characteristics of cornea. It can be recommended for IOP measurements of patients diagnosed with glaucoma including those cases where cornea pathology or cornea characteristics have been altered.

 

 

Thank you for your interest in Diaton Tonometer. Diaton Tonometry is a revolutionary approach to measuring intraocular pressure (IOP) THROUGH THE EYELID and OVER THE SCLERA - no contact with the cornea, no anesthesia or sterilization is required.

 

Nowadays transpalpebral scleral tonometry has no other  alternative in the world. It is the most favourable method to carry out  preclinical medical research of the population and , moreover, it works in such  complicated clinical cases when it is impossible to use classical tonometry methods.

The Diaton tonometer is light and easy to handle, I have successfully use this device and detected my client who potentially has glaucoma.  The Daiton tonometer is cheap and unique. It measure IOP through the eyelid and over the sclera with no contact to the cornea & causing no discomfort to my client. It is simple and rapid. The Daiton tonometer has helped me to improve my business and I personally would  recommend this device to be a useful company to any optomatrist!

 

 

IOP Measurement for Glaucoma Diagnostics and Treatment

Seppo Simila

 

During the training program worked out by Riika Ervastin and Jenny Nousiaisen the comarison tests of work of three different devices: Keeler Pulsair, Reichert Ophthalmic and Diaton were carried out. The average value of all three devices according to the test results were 11,7 (right eye) and 11,74 (left eye). The results of measurements of all three tonometersdiffer not much and are statistically reliable. The advantages of Diaton are : quickness, simpliscity and reliability of the measurement procedure, measurement in reclining position, small size and portability. IOP measurement throught the eyelid is safe and doesn´t disturb patients. Hospital staffs of Health Centers learn to use the device easily and quickly.

Diaton allows, without damage to the patient, to determine intraocular pressure and to control medications which can lead to possible ocular

hypertension, as their secondary effect.

Maintenance of the device in the family doctor’s office presents no difficulties. Diaton can be used either by a family doctor or by any trained medical staff within the general practice department.

The transpalpebral tonometer works by pressing it to the closed eye and depressing a plunger that gently hits the lid. “By the amount of pressure exerted

on the plunger when striking the eyelid and slightly indenting the globe, it can judge the IOP within 2 to 4 mmHG, when compared with the Goldman

applanation tonometer (Haag Streit, Mason, Ohio), which is the standard of care,” Dr. Perry said.

He said he did a study where he evaluated 100 consecutive patients and found a 95% correlation with the Goldman tonometer, proving its accuracy.

However, there is a bit of a learning curve for some technicians. Dr. Perry said there was one technician in his practice whose results were always precise,

while others had outcomes that varied.

Thus, cornea thickness is the important factor of IOP evaluation and monitoring and requires the necessity of including corneal pachymetry

in the program of examination the patients with suspicion of glaucoma and hypertension, especially after various keratorefractive surgeries while

using the traditional corneal methods of ophthalmotonometry. At the same time clinical application of transpalpebral scleral diaton tonometer makes

it possible to evaluate IOP using only one device, the procedure being efficient, economical, simple in performance and requiring no additional instrumental

examination.

Emil W. Chynn, MD, FASC from Park Avenue LASEK stated, – “As a Cornea-Refractive trained specialist, I encounter many situations where Goldmann readings are inherently inaccurate–like post-LASIK, in cases of corneal edema, scarring, post-keratoprosthesis or transplant. In such cases, it’s both invaluable and reassuring to have the Diaton device available to measure IOP that’s independent of corneal pathology”

 

"It works," said Dr. Mark Latina, glaucoma specialist and the inventor of Selective Laser Trabeculoplasty (SLT), after revealing results of the study titled: "Accuracy of Transpalpebral Tonometer Diaton Compared to Goldmann Applanation Tonometer in Normal and Glaucomatous Eyes"

“Dear Sirs,

 

attached please find pictures of my recent activity at Mother Theresa's orphanage and old age home where 200 needy people underwent eye exam and glaucoma screening. Fifteen people were glaucoma suspects and 3 with advanced glaucoma.

This screening would have not been possible without your generous donation of Diaton tonometer, a wonderful marvel of technology, that made this massive screening for glaucoma an easy one and with perfect accuracy.

Old age people normally have dry eyes, poor tear film quality, where there is a risk of corneal damage with Schiotz tonometry and applanation tonometry, you also need use of lots of fluoroscein dye because it dries up fast.

With Diaton tonometer this was not a problem ! Diaton tonometer is the best and only device suitable for use with aged patients and those with dry eyes.

           

Thank you Diaton for wonderful device that’s going to help save sights of thousands of people.  

 

God bless.

Please go through attached pictures.

Kind regards,

Transpalpebral transscleral tonometry results were independent from biomechanical properties of the cornea, while GAT showed dependence of IOP-measurement on these properties. CCT corrected GAT IOP values before and after corneal surgery differ from each other, while Diaton tonometry values remain stable. In the whole group CCT corrected GAT and transpalpebral IOP-values were in a good agreement. This study confirms the reliability and

advantages of the clinical application of transpalpebral transscleral tonometry after photorefractive surgery

 

Dr. med. Alexey Dashevsky, Dashevsky Eye Clinic, Munich, Germany

 

 

 

 

 

"The Diaton, little instrument which allow to recording of IOP independently from stationary and expansive equipment like slit lamp and air puff machines, in seated or in lying position of the patient, and it is independent from mains supply . Transpalpebral measurement means that there are tissue layers between sensor and eye ball and it makes IOP recordings feasible in corneal disease, and outside the ophthalmic ward. Further research is now under way "

 

Our pilot results:

 

The goal was to determine the measurement errors of tonometer Diaton based on comparisons of the results obtained by three researchers – confident users of transpalpebral tonometer. Consecutive IOP measurements were conducted by three trained users in 25 normal patients (25 eyes) using one Diaton device. Priority choice of user and eye was random.

 

Exclusion criteria: ophthalmopathology capable to alleet the results of trans-palpebral trans-scleral Diaton tonometry.

Including: ophthalmopathology accompanied by disruption of the normal anatomy of the eyeball, corneal pathology and preceding refractive corneal surgery, including the contralateral eye, upper eyelid pathology (inflammatory disease, scarring, ectropion and/or entropion, and etc.),evident pathology of sclera and/or conjunctiva in the affected area of Diaton.

 

Trans-palpebral tonometry and Goldmann tonometry were performed by the standard method of IOP measurement in compliance with all requirements and regulations.

 

It should be noted that all researchers are experienced users of tonometers. Full compliance to all aspects of measuring technique was invariable condition for this research.
