Event-based software GPA I and II had excellent agreement. Event analysis showed earlier and greater sensitivity for detecting progression than VFI analysis and both had only moderate agreement. Trend analysis VFI is likely to detect progression in patients with a greater number of visual field tests and a longer follow-up time. The VFI analysis seems to be more accurate than MD analysis for determining rate of progression.

High-dose systemic steroid treatment did not show any beneficial effect in visual and anatomic outcomes when given during the acute phase of NAION. Furthermore, it caused serious complications in a third of the patients treated.

In inactive moderate-to-severe GO, the RIs of the CRA and OA are higher than in normal subjects. The authors hypothesized that increased RIs of inactive GO may be due to orbital extrinsic compression of vascular structures because decompression surgery leads to decreases in the RIs of both the CRA and OA.

There is a strong correlation between GPA identification of glaucomatous progression and a thorough objective clinical assessment of the visual fields. GPA could be a useful test to aid clinicians in the detection of glaucomatous progression, with high specificity, strong positive likelihood ratio, and good sensitivity and negative likelihood ratio.

Purpose To compare intrascleral blebs characteristics after deep sclerectomy (DS) with three intrascleral implants using the Visante anterior segment optical coherence tomography. Methods This is a cross-sectional study including 60 eyes of 51 patients that underwent DS with Sk-Gel, Esnoper, and Aquaflow implant. Intraocular pressure (IOP) measurement, slit-lamp examination, and Visante scans were performed the same day in all the patients. Visante scans were done through the intrascleral bleb at 451, 901, and 1351 and the bleb height was measured. Results Sk-Gel was used in 19 eyes (31.66%), Esnoper in 22 eyes (36.66%), and Aquaflow in 19 eyes (31.66%). The median time lapsed from the surgery was 15.50 months 25th and 75th percentiles (p 25 8.25; p 75 20). The median IOP was 13 mm Hg (p 25 10; p 75 15), with no significant differences among implants (P ¼ 0.232). Overall, the correlation between the scleral bleb height and the IOP was statistically significant at 451 (r ¼ À0.359; P ¼ 0.004), 901 (r ¼ À0.410; P ¼ 0.001), and 1351 (r ¼ À0.417; P ¼ 0.001). However, Sk-Gel did not show any statistically significant correlation between the scleral height and IOP whereas the other two groups (Esnoper and Aquaflow) showed a significant correlation. There were no differences in the bleb height among implants. Conclusion There was a moderate inverse correlation between the scleral bleb height and the IOP measurement after DS with Esnoper and Aquaflow implants. There were no differences in bleb height among the three implants.
