RESUMO

BACKGROUND: This study aims to evaluate the efficacy and safety of extended depth of focus (EDOF) intraocular lenes (IOLs) in cataract surgery. METHODS: All comparative clinical trials that involved bilaterally implanting EDOF IOLs in patients with cataract were retrieved from the literature database. We used random effects models to pool weighted mean differences (WMD) and risk ratio (RR) for continuous and dichotomous variables, respectively. RESULTS: Nine studies with a total of 1336 eyes were identified. The subgroup analysis was conducted according to the type of IOLs used in the control group. Compared with monofocal IOLs, EDOF IOLs produced better uncorrected intermediate visual acuity (WMD: -0.17, 95% CI: - 0.26 to - 0.08, P = 0.0001) and uncorrected near visual acuity (WMD: -0.17, 95% CI: - 0.21 to - 0.12, P < 0.00001). EDOF IOLs resulted in reduced contrast sensitivity, more frequent halos, however, higher spectacle independence (RR: 2.81, 95% CI: 1.06 to 7.46, P = 0.04) than monofocal IOLs. Compared with trifocal IOLs, EDOF IOLs produced worse near visual acuity (MD: 0.10, 95% CI: 0.07 to 0.13, P < 0.0001). EDOF IOLs performed better than trifocal IOls in contrast sensitivity, and there were no significant difference in halos and spectacle independence. Serious postoperative complications were rare, with no adverse events were reported in most studies. CONCLUSIONS: Increasing the risk of contrast reduction and more frequent halos, EDOF IOLs provided better intermediate and near VAs than monofocal IOLs. At the expense of near vision, patients receiving EDOF IOLs have better contrast sensitivity than those receiving trifocal IOLs. Halo incidence and spectacle independence of EDOF IOLs were similar to those of trifocal IOLs.

RESUMO

BACKGROUND: To evaluate the efficacy of epiretinal membrane removal in patients with good best-corrected visual acuity (BCVA) for improving visual function and quality of life (QOL). METHODS: This prospective case study compared 37 subjects with preoperative BCVA ≦ 0.046 logMAR (Good group) to 35 patients with 0.10-0.52 logMAR (Moderate group) at 3 and 6 months. Linear mixed-effect models were used for statistical analysis. The primary outcome was the horizontal metamorphopsia score (MH) at 6 months postoperatively (post-6 M), while secondary outcomes were postoperative BCVA, vertical metamorphopsia score (MV), aniseikonia, stereopsis and central foveal thickness. In the Good group, QOL was assessed using the National Eye Institute Visual Functioning Questionnaire-25 (NEI VFQ-25) at 6 and 12 months. RESULTS: MH was significantly improved at post-3 M and post-6 M in the both groups but there were no significant differences between the two groups. MV showed no improvement at the final observation in either group. LogMAR BCVA was significantly improved at post-6 M in the Good group, which had significantly better vision than the Moderate group. Preoperative vertical and horizontal aniseikonia scores remained unchanged in the Good group at post-6 M but worsened in the Moderate group. The NEI VFQ-25 score improved in the Good group, reflecting improved general health, general vision, and mental health. CONCLUSIONS: Early epiretinal surgery for patients with BCVA ≦ 0.046 logMAR was effective for improvement of HM, BCVA, and QOL and prevented worsening of aniseikonia.

RESUMO

BACKGROUND: A near vision game has been developed for the autostereoscopic screen of the Nintendo 3DS console. Ease of use and time for testing by non-English-speaking patients was not known. METHODS: Adult and pediatric patients in a remote Burma clinic were compared with US military staff with each performing conventional near acuity, Stereo Fly, and Ishihara color in addition to PDI Check game, so results could be correlated and timed. RESULTS: Seventeen Burma adults (aged 19-58), 20 Burma children (aged 7-15), and 14 US military staff (aged 21-36) completed the testing. Conventional testing correlated with PDI Check for stereo (P < 0.001), acuity oculo dexter (P < 0.01), acuity oculo sinister (P < 0.01). For visual acuity and stereopsis, the intraclass coefficient was 0.55 [95% confidence interval (CI) 0.28-0.72] and 0.62 (95% CI 0.41-0.77) respectively, but with few color deficient cases color was 0.30 (95% CI -0.05 to 0.60). The time in seconds to complete near vision testing with PDI Check (172 ±â€Š27, overall; 198 ±â€Š34, Burma; 99 ±â€Š20, military) was significantly (25% ±â€Š18%) briefer than conventional testing (226 ±â€Š31, overall; 270 ±â€Š34, Burma; 126 ±â€Š20, military). The Burma patients took significantly longer than the military staff (234 ±â€Š25 vs 112 ±â€Š14, P < 0.01). Time for Burma children did not differ from Burma adults for PDI (109 ±â€Š47 vs 217 ±â€Š54, P = 0.42) and for conventional testing (266 ±â€Š51 vs 275 ±â€Š52, P = 0.80). CONCLUSIONS: Non-English-speaking Burma children and adults were able to reliably perform 3 types of near vision testing with a Nintendo 3DS game 25% quicker than the 2 to 3 minutes for conventional methods. They were slower than experienced US military staff adults.

RESUMO

PURPOSE: The aim was to study the visual performance of a new refractive extended depth of focus (EDOF) intraocular lens (IOL). DESIGN: Prospective, comparative study. METHODS: Consenting patients with age-related cataract willing for bilateral cataract surgery within 2 weeks were implanted with the Supraphob EDOF IOL and those willing for 1 eye surgery were implanted with a monofocal IOL. The uncorrected and best-corrected distance, intermediate and near visual acuity, and contrast sensitivity were evaluated at 1 and 3 months postoperatively. We also inquired about glare, halos, difficulties in night driving, requirement for spectacles, and overall satisfaction with vision. RESULTS: The Supraphob EDOF group (n = 72 eyes) and the monofocal IOL group (n = 54 eyes) were comparable with respect to all preoperative parameters including biometry, visual acuity, and cataract status. The mean age of participants was 58.4 ±â€Š10.6 years. Both groups had similar distance vision but the EDOF group had significantly better intermediate (0.2 ±â€Š0.2 logMAR vs 0.75 ±â€Š0.19 logMAR, P < 0.001) and near vision (median = N6 vs N12, P < 0.001) compared to the monofocal group at 3 months. The contrast sensitivity was similar in both groups. Patients in the EDOF IOL group had much greater satisfaction for intermediate and near vision. Less than 10% patients reported glare, halos, and difficulty in driving at night in the EDOF group. CONCLUSIONS: The Supraphob EDOF IOL was effective in improving the distance, intermediate and near vision in majority of patients, and retained good contrast sensitivity with most patients reporting excellent satisfaction.

RESUMO

PURPOSE: To compare the effect of intraocular lens (IOL) decentration on the optical quality in patients with implantation of three IOLs: monofocal, extended depth of focus (EDOF), and bifocal. METHODS: Patients had cataract surgery with implantation of one of the three above-mentioned IOLs. Higher order aberrations (HOAs), modulation transfer function (MTF), point spread function (PSF), retinal straylight, and dysphotopsia phenomena were evaluated 3 months after surgery. IOL decentration was quantified as the distance between the visual axis center and the IOL center using the OPD-Scan III aberrometer (Nidek Co., Ltd., Gamagori, Japan). The patients who received each IOL type were then divided into two subgroups (decentration of ⩽ 0.25 or > 0.25 mm) to analyze the effect of IOL decentration on these optical qualities. RESULTS: The study included 54 eyes (54 patients), with 18 eyes in each IOL group. The distance of IOL decentration did not differ significantly among the three groups. With a decentration of more than 0.25 mm, MTF, PSF, and coma were only significantly deteriorated in the bifocal IOL (ZMB00; Abbott Medical Optics, Santa Ana, CA). HOAs, coma, PSF, and glare perception were better in the monofocal and EDOF IOLs than those in the ZMB00 IOL when decentration was more than 0.25 mm. Furthermore, IOL decentration was significantly correlated with HOAs, coma, MTF, and PSF in the ZMB00 IOL. CONCLUSIONS: The monofocal and EDOF IOLs are more immune to optical quality degradation caused by IOL decentration than the ZMB00 IOL. [J Refract Surg. 2019;35(8):484-492.].

RESUMO

BACKGROUND: To evaluate the clinical outcomes of extended depth of focus (EDOF) and monofocal intraocular lenses (IOLs) that share identical aspheric platform and compare their visual acuity tolerance to postoperative refractive errors. METHODS: This non-randomized, prospective comparative study included 120 eyes undergoing cataract surgery with implantation of either Tecnis ZCB00 IOL (Abbott Medical Optics Inc., Santa Ana, CA) (monofocal group: 60 eyes of 30 patients) or Tecnis Symfony IOL (Abbott Medical Optics, Inc.) (EDOF group: 60 eyes of 30 patients). Monocular and binocular visual outcomes, changes in refraction, defocus curve, contrast sensitivity, and perception of photic phenomena (Halo & Glare Simulator; Eyeland Design Network, Vreden, Germany) were evaluated 3 months postoperatively. To compare the refractive tolerance, each group was divided into three subgroups according to the postoperative uncorrected distance visual acuity (UDVA) and postoperative spherical equivalent (SE). RESULTS: In the EDOF group, the mean 3-months postoperative monocular UDVA, intermediate (UIVA), and near (UNVA) visual acuities were 0.03 ± 0.07, 0.09 ± 0.15, and 0.24 ± 0.16 logMAR, respectively. A total of 100, 96.55, and 68.97% of eyes in the EDOF group achieved binocular UDVA, UIVA, and UNVA values of 0.20 logMAR or better, respectively. In respect to refractive tolerance, the EDOF group showed higher SE values and statistically significantly better mean UDVA than the monofocal group in all subgroups, with UDVA of - 0.013 and 0.028 logMAR for EDOF and monofocal groups (p = 0.037), respectively, in the subgroup where SE was within ±0.50 D, UDVA of 0.004 and 0.048 logMAR for EDOF and monofocal groups (p = 0.046), respectively, in the subgroup where SE was within - 1.00 D, and UDVA of 0.020 and 0.083 logMAR for EDOF and monofocal groups (p = 0.026), respectively, in the subgroup where SE was more than - 1.00 D. The mean patient satisfaction scores for spectacle-free distance, intermediate, and near visual acuities were 86.0, 85.0, and 66.0, respectively. CONCLUSIONS: The EDOF IOL provided excellent postoperative visual outcomes in far and intermediate distances, with high patient satisfaction rate. Regarding the postoperative refractive tolerance to SE, the Tecnis Symfony IOL showed better tolerance to residual postoperative refractive error than the monofocal IOL with the same material and optical platform.

RESUMO

BACKGROUND: Evaluation of clinical and functional results of a new extended depth of focus intraocular lens (EDOF-IOL). METHODS: Fourteen cataract patients (28 bilateral implantations) were assessed for uncorrected (UDVA) and corrected (CDVA) distance visual acuities; uncorrected (UNVA), distance-corrected (DCNVA) and best corrected (CNVA) near visual acuities; and uncorrected (UIVA) and distance-corrected (DCIVA) intermediate visual acuities - as well as binocular defocus curves. Photopic and mesopic contrast sensitivity was recorded. Reading acuity was evaluated using an electronic reading desk at fixed distances and at the patient's preferred near and intermediate distances. Visual symptoms were assessed with a halo and glare simulator plus a patient questionnaire which also recorded quality of life. RESULTS: Median postoperative monocular UDVA was 0.13logMAR (range - 0.08 to 0.42logMAR), median CDVA was - 0.01logMAR (range - 0.20 to 0.22logMAR), median UIVA at 80 cm was - 0.05logMAR (range - 0.18 to 0.58logMAR) and median UNVA at 40 cm was 0.14logMAR (range - 0.10 to 0.64logMAR). Binocular uncorrected reading acuity was 0.10logMAR at 40 cm and 0.11logMAR at 80 cm. Patients preferred a median intermediate reading distance of 62.8 cm over the predetermined 80 cm, which allowed them to read smaller letter size but did not improve reading acuity. Patients reported a high rate of spectacle independence and satisfaction in everyday life and little to no dysphotopsia. CONCLUSION: The Mini WELL Ready IOL provided good postoperative functional results at far and intermediate distances and improved the visual and reading acuity at reading distance. The lens caused little to no dysphotopsia. TRIAL REGISTRATION: The study protocol was registered at the German Clinical Trials Register: DRKS00007837 (Registered Date: March 9th, 2015).

RESUMO

BACKGROUND: To describe the clinical characteristics and the outcomes of strabismus surgery for acute acquired comitant esotropia (AACE). METHODS: Medical records of 45 AACE patients were retrospectively analyzed. The insertion location of medial rectus was compared between the AACE patients and comitant exotropic patients. The location was also compared with those measured in other studies. Surgical outcome measurements included amount of deviation and level of binocularity at last follow-up. RESULTS: The distance from medial rectus to limbus was shorter in AACE patients than in patients with comitant exotropia. The distance was also shorter in AACE patients than patients in other studies. Out of the 45 patients, 2 had neurological diseases. Neostigmine test was negative in all patients. The age at onset of AACE was 5-47 years (mean 19.1 ± 7.3 years), one patient was 5 years (2.2%), 20 patients were 11-17 years (44.5%) and the other 24 patients were 18-47 years old (53.3%). The mean cycloplegic refraction was - 4.1 ± 3.0 diopters (D) and 41 patients were myopic (91%). The angle of deviation was 40.5 ± 19.5 prism diopters (PD) at distance and 35.6 ± 19.9PD at near preoperatively. The angle was 0.8 ± 1.6 PD at distance and 0.7 ± 1.8 PD at near postoperatively. Diplopia resolved in patients who underwent strabismus surgery, with no recurrence during the follow-up period. Thirty patients had stereopsis postoperatively. CONCLUSIONS: AACE seems to occur mostly in older children and adults and myopes. The distance from the insertion to limbus of medial rectus was shorter in patients with AACE. Good results can be achieved by strabismus surgery.

RESUMO

Most studies on visual working memory (VWM) and spatial working memory (SWM) have employed visual stimuli presented at the fronto-parallel plane and few have involved depth perception. VWM is often considered as a memory buffer for temporarily holding and manipulating visual information that relates to visual features of an object, and SWM for holding and manipulating spatial information that concerns the spatial location of an object. Although previous research has investigated the effect of stereoscopic depth on VWM, the question of how depth positions are stored in working memory has not been systematically investigated, leaving gaps in the existing literature on working memory. Here, we explore working memory for depth by using a change detection task. The memory items were presented at various stereoscopic depth planes perpendicular to the line of sight, with one item per depth plane. Participants were asked to make judgments on whether the depth position of the target (one of the memory items) had changed. The results showed a conservative response bias that observers tended to make 'no change' responses when detecting changes in depth. In addition, we found that similar to VWM, the change detection accuracy degraded with the number of memory items presented, but the accuracy was much lower than that reported for VWM, suggesting that the storage for depth information is severely limited and less precise than that for visual information. The detection sensitivity was higher for the nearest and farthest depths and was better when the probe was presented along with the other items originally in the memory array, indicating that how well the to-be-stored depth can be stored in working memory depends on its relation with the other depth positions.

RESUMO

Technology for developing three-dimensional (3D) virtual models in anatomical sciences education has seen a great improvement in recent years. Various data used for creating stereoscopic virtual models have also been constantly improving. This paper focuses specifically on the methodologies of creating stereoscopic virtual models and the techniques and materials used in developing stereoscopic virtual models from both our previous studies and other published literature. The presentation and visualization of stereoscopic models are highlighted, and the benefits and limitations of stereoscopic models are discussed. The practice of making 3D measurements on the lengths, angles, and volumes of models can potentially be used to help predict typical measurement parameters of anatomical structures and for the placement of surgical instruments. Once stereoscopic virtual models have been constructed, their visualization and presentation can be implemented in anatomy education and clinical surgical trainings.

RESUMO

Aim: New methods of measurement require testing to evaluate test validity. This study compares stereoacuity results of the Lang Stereopad to other common clinical stereoacuity assessments in a normal vision population. Methods: A prospective cross-sectional study was conducted comparing the Lang Stereopad stereoacuity results to results from the Lang II, Frisby, and TNO stereo tests. Mean stereoacuity values and their correlation with inter-ocular visual acuity difference were compared for each stereo test. Results: 98 subjects (mean age of 33.5 years, SD 14.1; 39 males and 59 females) with normal parameters of visual function underwent multiple stereotest assessments. Median stereoacuity values were the lowest (i.e. more detailed stereoacuity) when using the Frisby stereotest (median 40"; 20-170" [minimum-maximum]) and TNO stereotest (median 60"; 15-480"). In comparison, medians were about double at 100" (50-800") for the Lang Stereopad and greater at 200" (200-200") for the Lang II stereotest. There was no correlation for each stereotest with interocular visual acuity differences. Conclusions: The Lang Stereopad test is easy to administer and it has certain advantages such as no requirement for additional test glasses. It is a useful assessment to add to the clinical armamentarium for binocular assessment of stereopsis. The Lang Stereopad does not agree well with other stereo tests such as the TNO and Frisby but provides a greater stereoacuity test range than the Lang II. The Lang Stereopad now requires testing in a clinical population in which stereoacuity is a pre-requisite part of the assessment.

RESUMO

PURPOSE: To evaluate visual outcomes at different distances (near, intermediate, and far), depth of focus, optical quality, quantitative dysphotopsia, and patient satisfaction in two groups. METHODS: The extended depth of focus (EDOF) only group (n = 40 eyes) was implanted bilaterally with an EDOF intraocular lens (IOL) and the mixed group (n = 40 eyes) was implanted with the same EDOF IOL in the dominant eye and a trifocal IOL in the fellow eye. At the 3-month postoperative visit, refractive outcomes and monocular and binocular uncorrected (UDVA) and corrected (CDVA) distance visual acuities for far UDVA, CDVA, distance-corrected intermediate visual acuity (DCIVA) at 80 cm, uncorrected near visual acuity (UNVA), distance-corrected near visual acuity (DCNVA) at 40 cm, and binocular defocus curve were evaluated. RESULTS: The mean spherical equivalent (SE) 3 months postoperatively was -0.16 ± 0.41 diopters (D) in the EDOF only group and -0.39 ± 0.63 D in the mixed group. In the EDOF only group, binocular visual acuities were: UDVA = -0.04 ± 0.07 logMAR (20/18); CDVA = -0.04 ± 0.06 logMAR (20/18); DCIVA (80 cm) = 0.07 ± 0.19 logMAR (20/23); DCNVA (40 cm) = 0.32 ± 0.15 logMAR (20/42); and UNVA (40 cm) = 0.24 ± 0.17 logMAR (20/35). In the mixed group, binocular visual acuities were: UDVA = 0.03 ± 0.09 logMAR (20/21) (P = .08); CDVA = -0.01 ± 0.07 logMAR (20/20) (P = .25); DCIVA (80 cm) = 0.24 ± 0.23 logMAR (20/35) (P = .08); DCNVA (40 cm) = 0.19 ± 0.07 logMAR (20/31) (P = .03); and UNVA (40 cm) = 0.18 ± 0.10 logMAR (20/30) (P = .37). CONCLUSIONS: Effective restoration of visual acuity was demonstrated in both groups, with high levels of visual quality and patient satisfaction. Better results in near visual acuity were demonstrated in the mixed group. [J Refract Surg. 2019;35(7):408-416.].

RESUMO

PURPOSE: To evaluate clinical and patient-reported outcomes of a new extended depth of focus intraocular lens (IOL). METHODS: Data of patients treated between September 2017 and September 2018 who underwent a refractive lens exchange/cataract surgery with an implantation of the AT LARA 829MP IOL (Carl Zeiss Meditec AG, Jena, Germany) and attended the 1-week, 1-month, and 3-month follow-up visit were reviewed. RESULTS: At 3 months, the percentage of eyes within ±0.50 diopters (D) of emmetropia was 86.7%. The mean binocular uncorrected distance visual acuity was -0.05 ± 0.09 logMAR and the mean binocular unaided near vision was 0.26 ± 0.14 logMAR. Of all patients, 90.3% were satisfied with their vision. The percentage of patients spectacle-free for near and distance vision was 83.6% and 95.4%, respectively. On a scale from 1 (no difficulty) to 7 (severe difficulty), there was an average 1.2 to 1.4 units increase in glare, halo, and starburst between the preoperative and 1-month visit, and a decrease of 0.2 to 0.3 units between the 1- and 3-month visit. CONCLUSIONS: The new extended depth of focus IOL provided reasonable unaided near and distance vision, as well as spectacle independence and patient satisfaction.

RESUMO

PURPOSE: To assess visual outcomes and patient satisfaction for trifocal and extended depth of focus (EDOF) intraocular lenses (IOLs) compared to monofocal IOLs with and without monovision. METHODS: Consecutive patients underwent bilateral cataract extraction surgery and implantation of either monofocal IOLs, monofocal IOLs using monovision, EDOF IOLs, or trifocal IOLs. Patients with preoperative biometric data, postoperative refraction, and visual acuity who completed a questionnaire regarding satisfaction and side effects were included. Visual outcome, spectacle independence, patient satisfaction, and subjective photic phenomena were assessed. RESULTS: Each group comprised 50 patients (100 eyes). The mean postoperative uncorrected distance, intermediate, and near visual acuities (logMAR) were: 0.17 ± 0.14 (Snellen 20/30), not applicable, and not applicable for monofocal; 0.08 ± 0.12 (Snellen 20/24), not applicable, and 0.07 ± 0.12 (Snellen 20/23) for monovision; 0.03 ± 0.08 (Snellen 20/21), 0.08 ± 0.12 (Snellen 20/24), and 0.23 ± 0.17 (Snellen 20/34) for EDOF; 0.07 ± 0.09 (Snellen 20/23), 0.08 ± 0.11 (Snellen 20/24), and 0.02 ± 0.06 (Snellen 20/21) for trifocal. Spectacle independence was reported by 36%, 70%, 74%, and 92% of patients, respectively. Postoperative halos and/or glare were experienced by 2%, 6%, 14%, and 38%, respectively, of which 2%, 0%, 6%, and 10%, respectively, were functionally disturbing. A total of 64%, 72%, 78%, and 76%, respectively, would choose the same IOL again. CONCLUSIONS: Patient satisfaction rates were high in all groups. Trifocal IOLs were more effective in improving unaided whole range of vision, but were associated with a higher rate of photic phenomena. The EDOF IOL and monovision provided partial spectacle independence with less photic phenomena. [J Refract Surg. 2019;35(7):434-440.].

RESUMO

PURPOSE: To evaluate the ability of the PDI Check (PDI Check LLC, Anchorage, AK) near vision screening game to assess monocular acuity, stereopsis, suppression, and color. METHODS: Children and adults consented to perform the PDI Check Quick Screening game following conventional near testing of patched Rosenbaum acuity, Titmus Fly stereo, Worth 4-dot, and Ishihara color. Time to complete each test and preferred method were recorded. RESULTS: A total of 77 patients (5 to 63 years old) attempted all tests. There was a positive correlation between the PDI Check and conventional tests for all visual tasks. Using previously determined instrument referral criteria, sensitivity/specificity was determined for right acuity (67%/91%), left acuity (55%/94%), stereopsis (87%/95%), red-green color (80%/99%), and ocular suppression (58%/98%). Screening time was 202 ± 96 versus 99 ± 42 seconds for the PDI Check and the game was preferred by 87%. CONCLUSIONS: The PDI Check provided a valid assessment of near vision in less than half the time of conventional testing without patches or goggles. This Quick Screening version may help eye technicians and physicians with time efficiency in the frequent task of near visual assessment. [J Pediatr Ophthalmol Strabismus. 2019;56(4):234-237.].

RESUMO

Background/Aim: Strabismus surgery could achieve motor alignment and improve health-related quality of life (HRQOL) in adults with large angle exotropia, but whether it could improve binocularity and whether the binocularity is associated with HRQOL are unknown. The aim of this study is to evaluate the binocularity and HRQOL following successful surgical correction of childhood large angle exotropia in adults. Methods: Consecutive adults with childhood large angle exotropia (≥90 prism diopters) who underwent strabismus surgery in the Department of Ophthalmology and Vision Science, Eye and ENT Hospital, Shanghai Medical School, Fudan University were enrolled. Static and dynamic stereopsis tests were performed before surgery and 1 month after surgery. At the same time, Adult Strabismus-20 (AS-20), and Amblyopia and Strabismus questionnaire (A&SQ) were investigated. Results: A total of 29 adults achieved successful alignment: 18 intermittent exotropes (IXT) and 11 constant exotropes (CXT). One month after surgery, stereopsis was demonstrated better in all types of tests (p < .05 for all comparisons). Twelve patients gained normal stereopsis. More patients in IXT group gained normal stereopsis than in CXT group (x2 = 7.62 p = .008). All HRQOL scores showed statistically significant improvement after surgery (p < .05 for all comparisons). IXT group had more changes of the composite score (t = 2.24, p = .03) and the functional score (t = 2.92, p = .007) of AS-20, and the functional score (t = 3.06, p= .005) of A&SQ than CXT group. Only the change of the functional score of A&SQ was demonstrated a statistically significant correlation with the normal stereopsis (t = 2.67, p = .02). Conclusions: The stereopsis and HRQOL in adults with childhood large angle exotropia can be improved after successful surgical correction. More patients in IXT group gained normal stereopsis correlated with better functional aspects of HRQOL.

RESUMO

Purpose: We investigated how sensory eye dominance (SED) affects stereopsis when the half-images of random-dot-stereo stimuli had different interocular contrast. Methods: We measured crossed and uncrossed stereo disparity thresholds and reaction time to seeing random-dot-stereograms with variable interocular contrast differences (ICD), where ICD = (log10 [CLE] - log10 [CRE]) = -0.4, -0.2, 0, 0.2, or 0.4 log unit. The mean contrast of the stimuli, (log10 [CLE] + log10 [CRE])/2, remained constant at 1.2 log unit to ensure that the measured effect was solely due to ICD. We also measured SED using, respectively, dichoptic horizontal sine wave gratings with different phases (revealing SEDcombo) and dichoptic vertical and horizontal gratings (revealing SEDinhibition). Results: Both measures of SEDinhibition and SEDcombo revealed the observers had the same eye as dominant although the magnitudes differed. The observers had lower stereo thresholds and shorter stereo reaction time on stimuli with unequal interocular contrast when the non-sensory-dominant eye viewed the higher contrast half-image, suggesting a stimulus-compensating effect. We then estimated the ICD of random-dot-stereo half-images (compensating stimuli) that would lead to minimum stereo threshold (SEDstereo-threshold) and reaction time (SEDstereo-RT) based on the stereo performance and ICD relationship, and found that they were significantly smaller than SEDinhibition and SEDcombo. Conclusions: By linking SEDinhibition and SEDcombo with the effect of ICD on stereopsis, we provided further support for the notion that the stimulus-compensating effect is mediated by the interocular inhibitory and interocular gain control mechanisms. Furthermore, the interocular contrast for SEDstereo-threshold and SEDstereo-RT can be potentially applied for improving stereopsis in individuals with SED.

RESUMO

This chapter discusses the concept of Auxiliary Tools in depth perception. Four recent techniques are considered, that apply the concept in the domain of liver vasculature visualization. While an improvement is evident, the evaluations and conducted studies are found to be biased and not general enough to provide a convincing assessment. The chapter provides background information about human visual perception and a brief history on vascular visualization. Then four state-of-the-art methods are discussed. Finally, a comparative discussion points out objectives for future follow-up work.

RESUMO

PURPOSE: To report a case of a child with strabismus and delayed discovery of a metallic intraocular foreign body with good recovery of visual acuity and stereopsis with 36-month follow-up. METHODS: A 4-year-old girl was evaluated due to exotropia of right eye initiated 9 months before with progressive worsening. Visual acuity was 1.00 logMAR (20/200) in the right eye and 0.00 logMAR (20/20) in the left eye. Anterior segment evidenced a small paracentral corneal leukoma, posterior synechia and mild lens opacity in the temporal quadrant only in the right eye. Fundus examination in the right eye identified the presence of an intraocular foreign body, with appearance of metallic components surrounded by retinal pigmented endothelial cells atrophy. Full-field electroretinography (ERG) showed reduced amplitudes and delayed implicit times for both rods and cones in the affected eye. All tests were normal in the fellow eye. RESULTS: Pars plana vitrectomy was promptly performed in the right eye, followed by phacoemulsification with intraocular lens implantation 4 months later due to worsening of the lens opacification. The full-field ERG was repeated after the surgical procedures. The ERG showed mild worsening of all responses in the right eye. After 36 months of follow-up, visual acuity was 0.20 logMAR (20/32) with improvement of the ocular misalignment and with 60 s of arc stereopsis with ERG responses unchanged. CONCLUSION: In this young girl perforating ocular trauma with metallic material was lately diagnosed with strabismus as a sign of alert. Prompt surgical intervention and proper management were essential to provide reasonable visual function including some degree of stereopsis, even though retinal dysfunction characterized by ERG was persistent.
