Background: Goldman Applanation Tonometry (GAT), the gold standard of tonometry, is used without fluorescein in low-resource settings. Nevertheless, corneal biomechanics differ among population groups. Purpose: The aim of the study is to assess the relationship between GAT findings with and without fluorescein among glaucomatous and non-glaucomatous adults in Malawi. Methods: This was a cross-sectional quantitative study involving 22 glaucoma patients and 22 non-glaucoma patients at Mzuzu Central Hospital. We used a purposive sampling technique to select participants into the two groups. Next, we measured Intraocular pressure using Goldman Applanation Tonometry with and without fluorescein. Then we entered the data into SPSS version 25. We employed the Wilcoxon test to make comparisons based on age and gender. We considered the value of pResults: There is a statistically significant and strong positive correlation between nfGAT and fGAT among both glaucoma (r = 0.989, p< 0.001) and non-glaucoma (r = 0.955, pConclusion: The study suggests that the merits of intraocular pressure measured using Goldman Applanation Tonometry without fluorescein are not speculative, therefore the two techniques can be routinely used interchangeably in diagnosing and managing glaucoma. |
