Background: The aim is to compare the diagnostic results of Short Wavelength Automated Blue on Yellow Perimetry (SWAP) with Standard Automated White on White Perimetry (W-W) in glaucoma-suspect and glaucomatous patients and to evaluate the role of SWAP in the early detection of glaucomatous visual field deficits as they are usually discovered, using W-W, only when they have reached an advanced stage. Material and methods: In this cross-sectional comparative study, held in Tishreen University Hospital – Ophthalmology Department from January 2021 to January 2022, 51 eyes of 31 subjects were enrolled. they underwent full ophthalmological examination including bio microscopy, Intraocular Pressure (IOP) measurement by means of Goldmann's applanation tonometry, and color vision testing using Ishihara's plates. The participants were divided into two groups: a Glaucoma- suspect group (31 eyes) and a Glaucomatous group (20 eyes). Informed consent was obtained from all subjects after the nature and possible consequences of the procedure had been fully explained to them. As all included subjects were familiar with SAP, we conducted two tests on each subject; first SAP (G pattern) then SWAP using (OCTOPUS 900) perimeter. The two testing sessions were separated by resting periods. The reliability parameters, test duration and visual field global indices were compared between W-W and SWAP. Results: In the Glaucoma- suspect group Mean Sensitivity (MS) was significantly higher in W-W than SWAP (P:0.0001). Both Mean Defect (MD) and Square Root of Loss of Variance (sLV) were significantly higher in SWAP (P:0.0001). Reliability Factor was greater in SWAP but not statistically significant (P:0.07). In the Glaucomatous group MS was significantly higher in W-W (P:0.0001). MD was significantly higher in SWAP (P:0.0001), as well as sLV (P:0.04). Reliability Factor was significantly greater in SWAP (P:0.02). And Test Time was significantly longer in SWAP in both Glaucoma-suspect and Glaucomatous groups (P:0.0001 & P:0.002) respectively. Conclusion: This study showed that SWAP is superior to W-W in identifying patients with early glaucoma, ocular hypertension, glaucoma suspects and patients with progressive optic disc cupping and may therefore be quite useful for determining early and progressive changes in glaucoma. However, in order to conclude that SWAP is an early indicator of glaucomatous damage, longer follow-up is required. And with the longer time needed to conduct SWAP, W-W remains the gold standard with SWAP being a valuable tool in the process.
