For a study, researchers sought to see how varieties in intraocular pressure (IOP) relate to fluid progression in episcleral veins. A correlation was made between glaucomatous (n=20) and nonglaucomatous eyes (n=10). Before consuming 10 mL of water per kilogram of body weight, each subject was given a standard IOP and Hemoglobin video imaging (HVI). The IOP and HVI were reviewed for another hour using the same systematic approach. For semi-measuring conventional AO, the watery segment cross-sectional region (ACA) of the most obvious nasal and transient fluid veins was employed. Change in IOP and Aqueous column cross-sectional area (AqCA) from pattern during the water drinking test (WDT). Fluid stream attributes were additionally noticed. Top IOP height above standard was higher in the glaucoma bunch, with a typical IOP ascent of 39.7% on 1.6 ± 1.1 prescriptions, contrasted with 22.9% in the benchmark group (P=0.04). ACA expanded for glaucomatous and nonglaucomatous eyes in light of water ingestion (P<0.05). ACA fell by half in glaucomatous eyes (P=0.003) and 33% in non glaucomatous eyes (P=0.08), concentrating on culmination contrasts and the pinnacle estimation. IOP remained more than 30% raised in 8 glaucomatous eyes (40%) following an hour and no control eyes. In patients with and without glaucoma, the AO volume, as measured by ACA, grows in response to an increased intraocular pressure caused by an ingested water bolus. It was shown that glaucomatous eyes did not sustain an increase in fluid seepage, which might have led to a short recovery of IOP. Incorporating HVI as a component of the WDT could assist in the clinical direction and in monitoring patients’ responses to therapy.
