“…The fast macular thickness test consisted of six consecutive 6 mm radial line scans centered on the macula, each containing 128 A-scans taken in the single session lasting 1.92 seconds. 15 Six sets of intersecting and equally spaced scans were obtained (Figure 1). In OCT macular thickness map macula has been divided into 3 areas using 3 circles.…”

Aim To evaluate the effect of systemic arterial hypertension (SAH) on retinal optical coherence tomography (OCT) parameters and investigate whether a correlation exists between ambulatory blood pressure monitoring (ABPM) and OCT measurements. Material-methods: 115 SAH patients (225 eyes) and 123 healthy control cases (234 eyes) were included. ABPM was performed on 89 of 115 SAH patients. All patients underwent detailed ophthalmologic examination including imaging with OCT. SAH patients were divided into two groups (dippers, non-dippers) according to their nocturnal blood pressure (BP) reduction, and OCT measurements were compared. Results Average and superior retinal nerve fiber layer (RNFL) quadrants were significantly thin in hypertensive cases (p:0.002, p < 0.001, respectively). Cup area, cup/disk (c/d) area, and c/d horizontal ratios were wider; the rim area was smaller in hypertensive cases (respectively: p:0.024, p:0.017, p:0.003, p < 0.001). Total macular volume (TMV), the thicknesses in 1–3 and 1–6 mm of the macula were less in hypertensives (p < 0.001). There was no significant difference between dippers and non-dippers in RNFL thickness, macula and optic nerve head (ONH) parameters. Conclusion There were statistically significant differences between healthy cases and patients with SAH in terms of RNFL, macula thicknesses and ONH parameters.

“…1 -3 OCT is a relatively quick, noninvasive, and consistent method to assess and help diagnose retinal pathology. 4 Recent studies have focused on the impact of OCT scan density on the qualitative analysis of conditions such as AMD 5 and diabetic macular edema (DME), 6 showing that lower scan densities were inferior to higher scan densities. However, despite these findings, the authors concluded that the lower-density results remain clinically acceptable.…”

Purpose: Optical coherence tomography (OCT) is useful in diagnosing and monitoring retinal pathology such as age-related macular degeneration, diabetic macular edema (DME), central serous chorioretinopathy, and epiretinal membrane, among others. This study compared the ability of horizontal (H) 25-, 13-, and 7-cut macular OCT vs 24-, 12-, and 6-cut radial (R) macular OCT in identifying various macular pathology. Methods: This was a prospective study of 161 established patients evaluated at Wilford Hall Eye Center Retina Clinic between September and October of 2019. Pathology included age-related macular degeneration, central serous chorioretinopathy, DME, and epiretinal membrane, among others. Patients obtained 25-, 13-, and 7-cut H raster OCT as well as 24-, 12-, and 6-cut R OCT. Primary outcomes were sensitivity in detecting macular fluid and each macular abnormality. Results: The 24-cut radial (R24) OCT equally or out-performed the H25 (horizontal 25-cut OCT) in detecting macular fluid across all pathological groups. Generally, a higher number of cuts correlated with better detection of fluid. In detecting any macular abnormalities, H25, R24, and R12 had 100% sensitivity. R6 OCT had near 100% sensitivity across all groups, except for DME (95%). Overall, R OCT had better sensitivity (0.960) than H OCT (0.907) in detecting macular pathology. Conclusions: R outperformed H macular OCT in detecting fluid and other abnormalities. Clinically, both scanning patterns can be used by ophthalmologists in diagnosis and management of commonly encountered macular diseases. Technicians may be able to use a variety of these scans to screen for pathology prior to physician evaluation.
