Description of intervention(s) / exposure
Five hundred eyes of 250 patients attending the Ophthalmology Outpatient, Suez Canal University Clinic were measured for intraocular pressure using the same Goldmann applanation tonometer mounted on Haag-Streit Slit Lamp, measurement first were done with red free light without Fluorescein then other measurements were done with cobalt blue light and topical Fluorescein on the same eyes . The measurement for one patient take place in one session and all measurements takes 15 minutes per patient.

Outcomes
Primary outcome [1] 288526 0
The Mean Intraocular Pressure {IOP} was 15.23+/- 6.3 (SD) mm Hg using the red free light without Fluorescein while the mean was 15.78 +/- 6. 7 (SD) mm Hg using cobalt blue light and after application of Fluorescein in the conjunctival sac. On paired t test analysis, this difference was not significant.

Abstract
Purpose:
To evaluate the use of red free light in the measurement of intraocular pressure using a Goldmann applanation tonometer without Fluorescein.

Materials and Methods:
Five hundred eyes of 250 patients attending the Ophthalmology Outpatient, Suez Canal University Clinic were measured for intraocular pressure using the same Goldmann applanation tonometer mounted on Haag-Streit Slit Lamp, measurement first were done with red free light without Fluorescein then other measurements were done with cobalt blue light and topical Fluorescein on the same eyes .
Results:
The Mean IOP was 15.23+/- 6.3 (SD) mm Hg using the red free light without Fluorescein while the mean was 15.78 +/- 6. 7 (SD) mm Hg using cobalt blue light and after application of Fluorescein in the conjunctival sac. On paired t test analysis, this difference was not significant.
Conclusion:
Measurement of IOP with Goldmann appanation tonometer with red free light without the use of Fluorescein is easy, simple, save time and give an accurate IOP measurement compared to traditional measurement with cobalt blue light and topical Fluorescein.
