“…The authors of GPA have attributed this same fact21 to the greater sensitivity of the Progressor program with respect to the GCP software 22. However, recent studies have observed that the change in MD after cataract operation is small,23 In patients with glaucoma, using the SITA-standard strategy we have observed that cataract removal improves MD by about 1.2 dB on average 24. A similar result was reported after cataract surgery in the AGIS study, with an MD change of 1.3 dB 25…”

“…The effect of cataract extraction on PSD remains controversial. While a few reports did not show any PSD changes [42,43], other reports showed PSD deterioration after cataract surgery in patients with glaucoma [39,40]. A diffuse sensitivity loss due to cataract may mask focal defects in glaucomatous VFs.…”

PurposeTo investigate visual field changes after vitrectomy for macular diseases in glaucomatous eyes.MethodsA retrospective review of 54 eyes from 54 patients with glaucoma, who underwent vitrectomy for epiretinal membrane (ERM; 42 eyes) or macular hole (MH; 12 eyes). Standard automated perimetry (Humphrey visual field 24–2 program) was performed and analyzed preoperatively and twice postoperatively (1st and 2nd sessions; 4.7 ± 2.5, 10.3 ± 3.7 months after surgery, respectively). Postoperative visual field sensitivity at each test point was compared with the preoperative value. Longitudinal changes in mean visual field sensitivity (MVFS) of the 12 test points within 10° eccentricity (center) and the remaining test points (periphery), best-corrected visual acuity (BCVA), intraocular pressure (IOP), and ganglion cell complex (GCC) thickness, and the association of factors with changes in central or peripheral MVFS over time were analyzed using linear mixed-effects models. In addition, 45 eyes from 45 patients without glaucoma who underwent vitrectomy for epiretinal membrane (ERM; 34 eyes) or macular hole (MH; 11 eyes) were similarly examined and statistically analyzed (control group).ResultsIn glaucomatous eyes, visual field test points changed significantly and reproducibly; two points deteriorated only at the center and twelve points improved only at the periphery. Central MVFS decreased (p = 0.03), whereas peripheral MVFS increased postoperatively (p = 0.010). In the control group, no visual field test points showed deterioration, and central MVFS did not change significantly after vitrectomy. BCVA improved, GCC thickness decreased, and IOP did not change postoperatively in both groups. The linear mixed-effects models identified older age, systemic hypertension, longer axial length, and preoperative medication scores of ≥2 as risk factors for central MVFS deterioration in glaucomatous eyes.ConclusionsVisual field sensitivity within 10° eccentricity may deteriorate after vitrectomy for ERM or MH in glaucomatous eyes.

“…As MD is calculated based on the total deviation map, it is believed that its inherent limitation is the compound effect of diffuse depression caused by coexisting cataract. Therefore, the significant improvement in MD after cataract extraction is not a surprising result, and this has been proven in other studies [6][7][8][9][10][11].…”

“…Previous studies [2,[6][7][8][9][10][11] on open angle or mixed glaucomatous eyes have shown statistically significant changes in visual field parameters after cataract extraction. Similarly, cataract extraction was found to have significant impact on RNFL thickness measurements [12][13][14][15].…”

Objective: To evaluate the effect of cataract extraction on both visual field and retinal nerve fiber layer thickness measurements in primary angle closure glaucoma (PACG) eyes. Methods: Retrospective cohort study on 30 PACG eyes underwent cataract extraction. Changes in RNFL thickness and visual field parameters including mean deviation (MD), visual field index (VFI) and pattern standard deviation (PSD) were analyzed within 6 months before and after cataract extraction. Results: Overall, MD (p=0.003) and VFI (p=0.004) improved significantly after cataract extraction, whereas PSD showed no significant change (p=0.6). In the 10 eyes with MD worse than-20 dB, mean MD improved by 3.4 ± 3.56 dB (from-24.36 ± 3.06 dB to-20.96 ± 5.06 dB, p=0.01) and mean VFI improved by 16.25 ± 15.66% (from 23.38 ± 9.65% to 39.63 ± 20.83%, p=0.02). PSD showed no significant change after cataract extraction (p=0.07). In the 20 eyes with MD better than-20 dB, MD and VFI also improved postoperatively, but the changes did not reach statistical significance: mean MD improved by 1.64 ± 3.65 dB (from-11.57 ± 5.57 dB to-9.92 ± 5.36 dB, p=0.05) whilst mean VFI improved by 4.57 ± 12.29% (from 74.95 ± 17.95% to 79.52 ± 17.26%, p=0.07). RNFL thickness did not show any significant changes after cataract extraction (p=0.13). Conclusions: Both MD and VFI improved after cataract extraction, especially in eyes with pre-operative MD worse than-20 dB. PSD and RNFL thickness showed no significant change after cataract extraction.

Effect of Cataract Extraction on SITA Perimetry in Patients With Glaucoma

Abstract: In glaucoma patients examined with SITA-standard, MD improved but PSD change was statistically nonsignificant, after the cataract surgery. SITA-standard PSD can be used to monitor glaucoma progression in patients with coexisting glaucoma and cataract.
