| 1 | Characterization, passive and active treatment in strabismic amblyopia: a narrative review显示文摘Strabismic amblyopia is characterized by a distorted spatial perception.In this condition,the neurofunctional disorder occurring during first years of life provoke several monocular and binocular anomalies such as crowding,deficits in the accommodative response,contrast sensitivity,and ocular motility abilities.The inhibition of the binocular function of the brain by the misaligned amblyopic eye induces a binocular imbalance leading to interocular suppression and the reduction or lack of stereoacuity.Passive treatments such as occlusion,optical and/or pharmacological penalization,and Bangerter foils has been demonstrated to be potentially useful treatments for strabismic amblyopia.Recent researches have proved new pharmacological options to improve and maintain visual acuity af ter occlusion treatment in strabismic amblyopia.Likewise,the active vision therapy,in the last years,is becoming a very relevant therapeutic option in combination with passive treatments,especially during and after monocular therapy,in the attempt of recovering the imbalanced binocular vision. | Myriam Milla David P.Pinero | 2020 | International Journal of Ophthalmology(English edition)2020，13，7： | 3 |
| 2 | Comparative analysis of the efficacy of astigmatic correction after wavefront-guided and wavefront-optimized LASIK in low and moderate myopic eyes显示文摘AIM: To evaluate and compare the efficacy of the astigmatic correction achieved with laser in situ keratomileusis(LASIK) in eyes with myopic astigmatism using wavefront-guided(WFG) and wavefront-optimized(WFO) ablation profiles.METHODS: Prospective study included 221 eyes undergoing LASIK: 99 and 122 eyes with low and moderate myopic astigmatism(low and moderate myopia groups).Two subgroups were differentiated in each group according to the ablation profile: WFG subgroup,109 eyes(45/64,low/moderate myopia groups) treated using the Advanced Custom Vue platform(Abbott Medical Optics Inc.),and WFO subgroup,112 eyes(54/58,low/moderate myopia groups) treated using the EX-500 platform(Alcon).Clinical outcomes were evaluated during a 6-month follow-up,including a vector analysis of astigmatic changes.RESULTS: Significantly better postoperative uncorrected visual acuity and efficacy index was found in the WFG subgroups of each group(P≤0.041).Postoperative spherical equivalent and cylinder were significantly higher in WFO subgroups(P≤0.003).In moderate myopia group,a higher percentage of eyes with a postoperative cylinder ≤0.25 D was found in the WFG subgroup(90.6% vs 65.5%,P=0.002).In low and moderate myopia groups,the difference vector was significantly higher in the WFO subgroup compared to WFG(P<0.001).In moderate myopia group,the magnitude(P=0.008) and angle of error(P<0.001) were also significantly higher in the WFO subgroup.Significantlyless induction of high order aberrations were found with WFG treatments in both low and moderate myopia groups(P≤0.006).CONCLUSION: A more efficacious correction of myopic astigmatism providing a better visual outcome is achieved with WFG LASIK compared to WFO LASIK. | Mounir A.Khalifa Mahmoud F.Alsahn Mohamed Shafik Shaheen David P.Pinero | 2017 | International Journal of Ophthalmology(English edition)2017，10，2： | 2 |
| 3 | Interchangeability of corneal curvature and asphericity measurements provided by three different devices显示文摘AIM: To evaluate the interchangeability of keratometric and asphericity measurements provided by three measurement systems based on different optical principles.METHODS: A total of 40 eyes of 40 patients with a mean age of 34.1 y were included. In all cases, a corneal curvature analysis was performed with IOL-Master(IOLM), iDesign 2(ID2), and Sirius systems(SIR). Differences between instruments for flattest(K1) and steepest(K2) keratometric readings, as well as for magnitude and axis of corneal astigmatism were analyzed. Likewise, differences in asphericity(Q) between SIR and ID2 were also evaluated. RESULTS: Mean differences between devices for K1 were 0.20±0.21(P<0.001),-0.12±0.36(P=0.046) and-0.32±0.36 D(P<0.001) for the comparisons IOLM-SIR, IOLM-ID2 and SIR-ID2, respectively. The ranges of agreement for these comparisons between instruments were 0.41, 0.70, and 0.70 D. For K2, mean differences were 0.31±0.33(P<0.001),-0.08±0.43(P=0.265) and-0.39±0.38 D(P<0.001), with ranges of agreement of 0.65, 0.84, and 0.74 D. Concerning magnitude of astigmatism, ranges of agreement were in the limit of clinical relevance(0.49 D, P=0.011; 0.55 D, P=0.386; 0.43 D, P=0.05). In contrast, ranges of agreement were clinically relevant for astigmatic axis(26.68o, 33.83o and 18.37o, P≥0.121) and for Q between SIR and ID2(0.16, P<0.001). CONCLUSION: The keratometric corneal power, astigmatic axis and asphericity measurements provideby the three systems evaluated cannot be considered as interchangeable, whereas measurements of corneal astigmatism obtained with SIR and ID2 can be considered as interchangeable for clinical purposes. | David P.Pinero Roberto Soto-Negro Pedro Ruiz-Fortes Rafael J Pérez-Cambrodí Hideki Fukumitsu | 2019 | International Journal of Ophthalmology(English edition)2019，12，3： | 2 |
| 4 | Adjustable muscle plication:a new surgical technique for strabismic patients with high risk for anterior segment ischemia显示文摘INTRODUCTION Anterior ciliary arteries provide 70%of the vascular supply of the anterior segment.A significant interruption of the vascular flow of these arteries increases the risk for anterior ischemia.Although the frequency of this special condition is low after strabismus surgery(1:13 000)[1],its effects may involve substantial visual problems[2].We report the successful outcome of a new surgical approach for strabismus management in a case of high risk for anterior ischemia.Specifically,we show the correction of the horizontal ocular deviation by means of an adjustable | Carlos Laria David P.Pinero | 2015 | International Journal of Ophthalmology(English edition)2015，8，4： | 1 |
| 5 | Refractive error study in young subjects:results from a rural area in Paraguay显示文摘AIM:To evaluate the distribution of refractive error in young subjects in a rural area of Paraguay in the context of an international cooperation campaign for the prevention of blindness. METHODS:A sample of 1466 young subjects(ranging from 3 to 22 years old),with a mean age of 11.21±3.63 years old,were examined to assess their distance visual acuity(VA)and refractive error. The first screening examination performed by trained volunteers,included visual acuity testing,autokeratometry and non-cycloplegic autorefraction. Inclusion criteria for a second complete cycloplegic eye examination by an optometrist were VA <20/25(0.10 log MAR or 0.8 decimal)and/or corneal astigmatism ≥1.50 D. RESULTS:An uncorrected distance VA of 0 log MAR(1.0decimal)was found in 89.2% of children. VA <20/25 and/or corneal astigmatism ≥1.50 D was found in 3.9% of children(n=57),with a prevalence of hyperopia of 5.2%(0.2%of the total)in this specific group. Furthermore,myopia(spherical equivalent ≤-0.5 D)was found in 37.7% of the refracted children(0.5% of the total). The prevalence of refractive astigmatism(cylinder ≤-1.50 D)was 15.8%(0.6% of the total). Visual impairment(VI)(0.05≤VA≤0.3)was found in 12/114(0.4%)of the refracted eyes. Main causes for VI were refractive error(58%),retinal problems(17%,2/12),albinism(17%,2/12)and unknown(8%,1/12).CONCLUSION:A low prevalence of refractive error has been found in this rural area of Paraguay,with higher prevalence of myopia than of hyperopia. | Isabel Signes-Soler | 2017 | International Journal of Ophthalmology(English edition)2017，10，3： | 1 |

| 7 | Clinical outcomes at one year following keratoconus treatment with accelerated transepithelial cross-linking显示文摘This study evaluated the clinical outcomes in keratoconus corneas following accelerated transepithelial corneal collagen cross-linking(CXL)(Avedro KXL? system,Waltham,MA,USA) over one year of follow-up.The mean depth of the demarcation line measured by optical coherence tomography(OCT) was 205.19 μm.One month after surgery,a non-statistically significant change was noted in sphere(P= 0.18) and in spherical equivalent(P= 0.17),whereas a significant improvement was observed in corrected distance visual acuity(P=0.04).A significant change was observed in topographic astigmatism(P= 0.03) and posterior corneal a sphericity(P= 0.04).Accelerated transepithelial CXL may be a useful technique for the management of progressive keratoconus. | Alberto Artola | 2017 | International Journal of Ophthalmology(English edition)2017，10，4： | 0 |
| 8 | Visual function alterations in essential tremor: A case report显示文摘Our purpose is to report alterations in contrast sensitivity function(CSF)and in the magno,parvo and koniocellular visual pathways by means of a multichannel perimeter in case of an essential tremor(ET).A complete evaluation of the visual function was performed in a 69-year old patient,including the analysis of the chromatic discrimination by the Fansworth–Munsell 100 hue test,the measurement of the CSF by the CSV-1000E test,and the detection of potential alteration patterns in the magno,parvo and koniocellular visual pathways by means of a multichannel perimeter.Visual acuity and intraocular pressure(IOP)were within the ranges of normality in both eyes.No abnormalities were detected in the fundoscopic examination and in the optical coherence tomography(OCT)exam.The results of the color vision examination were also within the ranges of normality.A signi¯cant decrease in the achromatic CSFs for right eye(RE)and left eye(LE)was detected for all spatial frequencies.The statistical global values provided by the multichannel perimeter confirms that there were significant absolute sensitivity losses compared to the normal pattern in RE.In the LE,only a statistically significant decrease in sensitivity was detected for the blue-yellow(BY)channel.The pattern standard deviation(PSD)values obtained in our patient indicated that there were significant localized losses compared to the normality pattern in the achromatic channel of the RE and in the red-green(RG)channel of the LE.Some color vision alterations may be present in ET that cannot be detected with conventional color vision tests,such as the FM 100 Hue. | David P.Pinero Begona Monllor Vicenta Moncho Vicent J.Camps Dolores de Fez | 2015 | Journal of Innovative Optical Health Sciences2015，8，5： | 0 |
| 9 | Evaluation of a new nomogram for Ferrara ring segment implantation in keratoconus显示文摘AIM:To evaluate the short-term clinical outcomes of Ferrara rings in keratoconus using an optimized nomogram developed after several years of research and retrospective analysis of clinical data.METHODS:This prospective longitudinal non-comparative clinical trial evaluated 88 eyes of 88 patients(age 18-62 y)with keratoconus diagnosis from two Spanish centers.Ferrara ring segment(AJL Ophthalmic)implantation was performed in all cases,using the mechanical procedure in 25 eyes(28.4%)and a femtosecond laser-assisted procedure in 63 eyes(71.6%).The ring segments implanted in each case were selected using a new optimized nomogram that considered variables such as anterior corneal asphericity and astigmatism or the discrepancy among astigmatism and coma orientations.Visual,refractive,corneal topographic,aberrometric,and pachymetric changes after surgery were evaluated during a 3-month follow-up.RESULTS:The implants induced a significant refractive change as well as an improvement in uncorrected(UDVA)and corrected distance visual acuity(CDVA;P<0.001).Postoperative CDVA of 0.10 log MAR or better was achieved in 28.4%and 46.5%of eyes,respectively.Two eyes(2.3%)lost two or more lines of CDVA whereas a total of 53.5%of eyes gained lines of CDVA.A significant central anterior and posterior corneal flattening was induced(P≤0.003),with a significant reduction of anterior(P<0.001)and posterior corneal astigmatisms(P=0.048),and a change in anterior asphericity(P<0.001).Total primary coma(6 mm pupil)change was also statistically significant(preoperative 3.66±3.04μm vs postoperative 2.33±2.26μm,P<0.001).No significant differences were found in the effect of ring segments between cases implanted using the mechanical and femtosecond techniques(P≥0.101).CONCLUSION:The implantation of Ferrara rings based on the nomogram evaluated is safe and effective for promoting a visual rehabilitation in keratoconus,with a relevant control of primary coma aberration. | Joaquín Fernández Cristina Peris-Martínez Antonio Pérez-Rueda Sidi Mohamed Hamida Abdelkader María JoséRoig-Revert David P.Pinero | 2021 | International Journal of Ophthalmology(English edition)2021，14，9： | 0 |
