Background: Goldman applanation tonometry (GAT) is still the most accurate for measuring intraocular pressure (IOP). Usually, fluorescein eye drops are used in additional to topical anesthesia to gain the best visualization result. Objective: The main objective of the study is to compare the GAT values with and without fluorescein in adult Sudanese glaucomatous and nonglaucomatous population. Materials and Methods: In a cross-sectional hospital-based study, 400 patients were recruited from out patient's and glaucoma clinics at Makkah Eye Complex, Khartoum, in the period from December 2017 to January 2018. Different ages were classified into three groups, patients also classified into glaucoma (n = 200) and nonglaucoma (n = 200) patients, another classification according to gender. Then, IOP measurements with and without topical fluorescein were done by GAT. Results: Two hundred and sixteen (n = 216; 54%) were male and 184 (46%) were female, with an average age of 54.76 ± 24.5 years. Two hundred (50%) were glaucomatous, and the other 200 (50%) were nonglaucomatous. The average IOP with fluorescein was higher than without fluorescein by 13.1% (2.08 mmHg) and still was higher in comparison between non-Glaucomatous and glaucomatous with and without fluorescein up to 3. 41 mmHg (17.86%). Both results ± fluorescein and ± glaucoma were statistically significant (P = 0.000). There was a significant correlation between age and IOP values with fluorescein and between having glaucoma and IOP with fluorescein (P = 0.000), while there was nonsignificant correlation between sex and IOP measurements with fluorescein. Conclusion: There are statistically significant differences in IOP values by GAT either ± fluorescein or ± glaucoma. A significant correlation between age and IOP values either ± fluorescein or ± glaucoma were detected, but not to sex.
