Client Testimonials

Eastern Ophthalmic Supply & Repair, Inc.
EOSR has always been a top-notch company to do business with. When I opened my office Jerry helped me with all of my initial equipment needs. As my office grew both Jerry and William where able to help me meet my expansion needs. I have found that they deliver quality service on a continual basis whether it be new equipment purchases or repair and maintenance of existing equipment. They are always fast to answer questions and very willing to do what is best and easiest for me and my practice. I appreciate the time they take to initially understand my needs and the follow thru in meeting my needs in a very efficient way. I have recommended them to my professional friends and I would recommend EOSR to anyone who has any kind of equipment need.

Dr. Chuck Aldridge discusses his new Reichert ORA.

The Reichert Ocular Response Analyzer G3 is a very easy-to-use and easy-to-interpret instrument. The learning curve is very flat and once the practitioner becomes comfortable with the data displayed it takes evaluating glaucoma patients, as well as glaucoma suspects, to a new level of care.

My interpretation technique is now:
  1. Check the Waveform Score (WS). This lets me know the reliability of the test. The good news is when the tech is performing the procedure low scores are automatically flagged by presenting the score in orange text which lets them immediately knowing to repeat due to poor reliability of the current measurement.

  2. Since I am “old school” I next look at the IOPg. This number is the same as a Goldmann measurement and gives me a good reference number to compare to my prior Golmann tests.

  3. The CH (corneal hysteresis) is what I look at next.  A lot of data is coming out now showing a lower CH scores, especially with higher IOPg scores, are correlated to glaucoma progression.


The caveats here are…
  • If the patient has a borderline IOPg value but has a high CH value and no other signs of glaucoma (optic nerve changes, normal field screening, etc) then there is a good degree of comfort this patient is a glaucoma suspect and not a glaucoma patient.

  • If the patient has a relatively normal (or perhaps elevated) IOPg value but the CH values are abnormally low (along with optic nerve changes and/or abnormal vision field screening) this patient is a probable NTG or POAG patient and further testing is needed.

  • I generally do not get too wrapped up in IOPcc unless the patient has had prior refractive surgery causing the corneal thickness to be altered. Then IOPcc and CH can be more useful than IOPg and CH.
