“…Previous studies have also correlated reductions in reading speeds with reduced sensitivity on microperimetry (Edington et al. ), suggesting that reading tests uncover other aspects of visual dysfunction. Moreover, reading is more representative of the impact of vision on the QOL than Snellen VA, because it reflects real world function in patients with macular pathologies (Jackson & Owsley ; Kanonidou ).…”

Purpose Patients with proliferative diabetic retinopathy (PDR) treated with panretinal photocoagulation (PRP) can have abnormal visual functioning that may be missed by Snellen visual acuity alone. We investigated reading deficits in patients treated with PRP for PDR using the Minnesota reading (MNREAD) test. Methods Thirty patients treated with PRP and 15 controls underwent best‐corrected visual acuity (BCVA), the MNREAD, frequency doubling perimetry (FDP), and fundus photography. Panretinal photocoagulation (PRP)‐treated subjects were compared to controls on MNREAD results by two‐sample t‐tests and Wilcoxon tests and Pearson correlations were used to assess the association between performance on MNREAD and other central visual function tests within PRP subjects. Results Panretinal photocoagulation (PRP)‐treated patients had reduced MNREAD acuity (p < 0.0001) and increased critical print size (p = 0.01) compared to controls but not a significantly reduced maximum reading speed (p = 0.06). Logmar MNREAD acuity was strongly positive correlated with logMAR BCVA (r = 0.58, p = 0.0098) and strongly negatively correlated with FDP foveal threshold (r = −0.63, p = 0.0030). Maximum reading speed was positively correlated with FDP foveal threshold (r = 0.57, p = 0.0143) and FDP mean deviation (r = 0.51, p = 0.0432). Visual acuity did not correlate with the sensitivities on the FDP. Conclusion The MNREAD test reveals that PRP reduces reading ability and other aspects of macular function, and thus provides new understanding of how vision‐related quality of life is impaired. These findings may lead to improved means to evaluate and enhance vision following treatment for PDR.

“…Alternatively, a free ILM flap could be created and placed inside the macular hole, as chosen by the surgeon during the procedure. On all patients, fluid-air exchange and insufflation of SF 6 into the vitreous cavity were performed, taking special care that the ILM flap stayed in the correct position. This was done under visualization via intraoperative OCT (ReScan 700; Carl Zeiss Meditec AG, Jena, Germany).…”

“…In patients with diabetic macular oedema, central points in microperimetry were correlated with reading speed [6,7], indicating that microperimetry gives additional information on visual function, compared to distance corrected visual acuity (DCVA).…”

Purpose: Internal limiting membrane (ILM) flap transposition in surgical repair of macular holes represents a new technique offering good anatomical success rates with large macular holes. The aim of the study was to examine microperimetric outcomes 1 year after ILM flap transposition for surgical repair of macular holes. Methods: Patients with idiopathic macular holes scheduled for 23-G pars plana vitrectomy with ILM peeling, ILM flap transposition, and SF₆ tamponade were examined in a prospective case series. Distance corrected visual acuity (DCVA), optical coherence tomography, and microperimetry were measured before and 1 year after surgery. Results: In all eyes, closure of the macular hole could be achieved. While foveal sensitivity improved in 71%, perifoveal sensitivity improved in 86% of the cases. DCVA improved in 83% and was unchanged in 17% of the cases. Conclusions: Beside visual acuity, foveal and perifoveal macular sensitivity improved, underlining the functional success of surgery after ILM peeling with ILM flap transposition.

“…With the MNREAD Charts, patients with retinitis pigmentosa [ 87 ], AMD [ 88 , 89 ], macular pucker and macular hole surgery [ 90 ], diabetic macular edema [ 91 ], and albinism [ 92 ] have been investigated, and further studies about the reading performance of low-vision patients have been performed [ 93 – 98 ]. In one study, the reading acuity was examined with the Bailey–Lovie Word Reading Cards, and reading speed was investigated with the MNREAD test [ 89 ].…”

A new generation of logarithmic reading charts has sparked interest in standardized reading performance analyses. Such reading charts have been developed according to the standards of the International Council of Ophthalmology. The print size progression in these calibrated charts is in accordance with the mathematical background of EN ISO 8596. These reading charts are: the Bailey–Lovie Word Reading Chart, the Colenbrander English Continuous Text Near Vision Cards, the Oculus Reading Probe II, the MNREAD Charts, the SKread Charts, and the RADNER Reading Charts. The test items used for these reading charts differ among the charts and are standardized to various extents. The Bailey–Lovie Charts, MNREAD Charts, SKread Charts, and RADNER Charts are also meant to measure reading speed and allow determination of further reading parameters such as reading acuity, reading speed based on reading acuity, critical print size, reading score, and logMAR/logRAD ratio. Such calibrated reading charts have already provided valuable insights into the reading performance of patients in many research studies. They are available in many languages and thus facilitate international communication about near visual performance. In the present review article, the backgrounds of these modern reading charts are presented, and their different levels of test-item standardization are discussed. Clinical research studies are mentioned, and a discussion about the immoderately high number of reading acuity notations is included. Using the logReading Acuity Determination ([logRAD] = reading acuity equivalent of logMAR) measure for research purposes would give reading acuity its own identity as a standardized reading parameter in ophthalmology.
