Influence of cataract and intraocular lens surgery on health-related quality of life

PURPOSE: To evaluate the vision-related quality of life(QOL) in patients undergoing cataract surgery with the Japanese version of the 25-item National Eye Institute Visual Function Questionnaire (NEI VFQ-25). SUBJECTS AND METHODS: Subjects were 110 patients [70.4 +/- 9.2 (mean +/- standard deviation) years old] undergoing bilateral cataract surgery. Best-corrected visual acuity was 20/30 or worse in both eyes. The VFQ-25 was recorded before and 2 months after phacoemulsification and foldable intraocular lens implantation, and the influence of various clinical parameters was assessed. The VFQ-25 was also recorded in 69 glaucoma patients with visual field defects in both eyes, and in 31 normal subjects. RESULTS: The VFQ-25 scores before cataract surgery were as low as the scores obtained in glaucoma patients. Cataract surgery significantly improved VFQ-25 scores to the level of normal subjects Statistically significant improvements were observed in subscales such as general vision, near activities, distance activities, driving, peripheral vision, color vision, social functioning, dependency, role difficulties, mental health, and total score (p<0.001, paired t-test). The degree of improvement in VFQ-25 scores did not correlate with preoperative or postoperative visual acuity, uncorrected or corrected. The VFQ-25 scores improved more in younger patients, and improvement in the general vision subscale showed a significant negative correlation with age (r= -0.286, p=0.009, Pearson correlation coefficient). The degree of posterior subcapsular cataract in better eyes showed significant correlation with the improvement in subscales, such as distance activity (r =0.413, p<0.001), driving (r= 0.449, p=0.015), social functioning (r=0.308, p= 0.004), mental health (r=0.330, p=0.002), dependency (r=0.323, p=0.003), and total score (r=0.328, p=0.002). Other types of cataract had no correlation. Men tended to show more improvement in VFQ-25 scores by surgery than women, except for the dependency subscale. CONCLUSION: The current study quantitatively demonstrated that vision-related QOL is significantly impaired in patients with cataract, and that cataract surgery dramatically improves patients' QOL.     

Utility of the National Eye Institute VFQ-25 questionnaire in a heterogeneous group of multiple sclerosis patients

PURPOSE: To investigate the utility of the 25-Item National Eye Institute Visual Function Questionnaire (VFQ-25) in assessing visual function in a heterogeneous group of multiple sclerosis (MS) patients and to identify correlations of VFQ-25 scores with clinically relevant objective visual parameters. DESIGN: Comparative cohort study. METHODS: The VFQ-25 was distributed to 34 patients with clinically definite MS. Patients underwent a comprehensive ophthalmic examination, including Early Treatment Diabetic Retinopathy Study (ETDRS) visual acuity (V(A)), Pelli-Robson contrast sensitivity (CS), Humphrey visual field 30 to 2 (HVF), and Farnsworth-Munsell 100-Hue color vision (100-Hue). Expanded Disability Status Scores (EDSS) were recorded for each patient. Comparative analyses using chi2 tests and t tests were performed. Spearman rank correlation coefficients were computed to identify relationships between VFQ-25 scores and the aforementioned visual parameters. RESULTS: In comparison with a published reference group without ocular disease, MS patients had considerably worse VFQ-25 composite scores (P < .01), being similar to published cohorts of glaucoma and cataract patients. VFQ-25 composite scores were found to be modestly and significantly correlated with several clinical parameters, including: V(A) (r = -0.63, P < .001), CS (r = 0.60, P < .001), HVF (r = 0.53, P = .003), and 100-Hue (r = -0.48, P = .01). EDSS scores, the use of disease modifying agents, and having a history of previous optic neuritis did not correlate significantly with VFQ-25 composite scores. CONCLUSIONS: The VFQ-25 questionnaire is a sensitive and useful tool in assessing visual function in MS patients. Such patients have quality of life indices similar to glaucoma and cataract patients, underscoring the significance of visual symptoms in MS.     

The impact of cataract surgery on cognitive impairment and depressive mental status in elderly patients

PURPOSE: To evaluate the influence of cataract surgery on cognitive function and depressive mental status of elderly patients. DESIGN: Prospective, interventional case series. METHODS: The 25-Item National Eye Institute Visual Functioning Questionnaire (NEI VFQ-25), Mini-Mental State Examination (MMSE), and Beck Depression Inventory (BDI) are the measures designed to assess vision-related quality of life (QOL), cognitive impairment, and depressive mental status, respectively. These tests were performed before and two months after surgery in 102 patients undergoing phacoemulsification and intraocular lens implantation for bilateral cataract. RESULTS: The change in best-corrected visual acuity by surgery significantly correlated with the change in NEI VFQ-25 score (Pearson correlation, r = -0.310; P = .031). The change in NEI VFQ-25 score by surgery significantly correlated with the change in MMSE score (r = 0.306; P = .035) and the change in BDI score (r = -0.414; P < .001). The change in MMSE score showed significant correlation with the change in BDI score (r = -0.434; P < .001). CONCLUSIONS: Vision-related QOL, cognitive impairment, and depressive mental status are all strongly related with each other. Cataract surgery significantly improved vision-related QOL in elderly patients, and cognitive impairment and depressive mental status also improved in parallel with improvement in vision-related QOL.     

Influence of cataract surgery on automated perimetry in patients with glaucoma.

PURPOSE: To investigate the influence of cataract surgery on automated perimetry in patients with glaucoma. DESIGN: Interventional case series. METHODS: A total of 105 eyes of 105 consecutive patients with glaucoma who were scheduled for cataract surgery underwent Humphrey static threshold testing (30-2 program) before and at 1 month after surgery. These eyes were divided into two groups based on the presence of absolute or near absolute (dense) scotomata before surgery (minimum threshold value 5 decibels or less). Changes in numbers of the dense scotomata, mean deviation, pattern standard deviation, and corrected pattern standard deviation were analyzed. RESULTS: No significant changes were found in the numbers of dense scotomata and central dense scotomata within five-degree visual fields between before and after surgery. In the group with dense scotomata, the mean pattern standard deviation and corrected pattern standard deviation worsened significantly after surgery, whereas the mean deviation improved significantly. However, in the group without dense scotomata, the pattern standard deviation and corrected pattern standard deviation showed a slight improvement, whereas the mean deviation improved significantly. When the central scotoma was present in two or fewer meridians before surgery, the mean visual acuity after surgery reached 20/25 and was better than that in patients with three or four central scotomata (P =.0014). CONCLUSIONS: Cataract does not produce a dense scotoma on automated perimetry. However, because it does produce relative scotomata, actual glaucomatous visual field defects may be hidden to some extent. When a central dense scotoma is present before surgery in two or fewer meridians, the patient may well achieve substantial improvement in postoperative visual acuity.

Effects of cataract and scotoma on visual acuity: a simulation study.

Central field loss (CFL) and cataract both decrease visual acuity. For patients with CFL, visual acuity is further reduced when the acuity target is more visually complex. We tested visual acuity for targets of varying complexity (letters alone, letters flanked by one or two x's on each side, and words) in subjects with normal vision and in the presence of a simulated cataract, simulated scotoma, and their combination (scotoma + cataract). Visual acuity was best with normal vision and worst with scotoma + cataract for all of the acuity targets. There was little difference in visual acuity between the letters alone and flanked letters, and visual acuity was best for words under all vision conditions. The cataract had a greater impact on visual acuity when the subject's central visual field was clear (normal vision) than when it was occluded by the simulated scotoma.     

Impact of impaired vision and eye disease on quality of life in Andhra Pradesh

PURPOSE: To determine the impact of visual impairment and eye diseases on quality of life (QOL) in an older population of Andhra Pradesh in southern India. METHODS: The World Health Organization (WHO) QOL (WHOQOL) instrument was adapted as a health-related quality of life (HRQOL) instrument for administration to adults participating in the Andhra Pradesh Eye Disease Study. Participants aged 40 years and older (n = 3702), 99.4% of the 3723 eligible, who underwent interview and detailed dilated ocular eye evaluation by trained professionals were included in this study. Psychometric properties of the HRQOL instrument were evaluated among visually impaired people. Relationships among overall QOL scores and presenting visual acuity in the better eye, specific eye diseases, and demographic variables were examined. RESULTS: Internal consistency was high for the entire questionnaire (alpha = 0.94). Each item of the QOL scale had an adequate item-total correlation (range, 0.25-0.77) greater than 0.2. After adjusting for demographic variables and ocular disease, Subjects with blindness had significantly lower QOL scores. Subjects with glaucoma or corneal disease independent of visual acuity had lower scores than subjects without those eye diseases. Subjects with cataract or retinal disease had significantly lower scores than those without cataract or retinal disease in the model without visual acuity but not when visual acuity was added to the model. CONCLUSIONS: Decreased QOL was associated with the presence of glaucoma or corneal disease independent of visual acuity and with cataract or retinal disease as a function of visual acuity. Visual impairment from uncorrected refractive errors was not associated with decreased QOL.

Vision-related quality of life in corneal graft recipients

AimsTo assess the vision-related quality of life of corneal transplant recipients using the National Eye Institute Visual Function Questionnaire-25 (NEI VFQ-25), and to identify the socio-demographic factors that associate with patients' self-assessment of perceived visual function.MethodsThirty patients who received corneal transplants were included in this prospective observational, cross-sectional study. Socio-demographic and clinical data, including age, sex, systemic health status, employment status, visual acuity, reason of corneal transplantation, laterality of corneal graft, and follow-up period were collected. NEI VFQ-25 was scored using Rasch analysis. Subgroup analyses were also performed.ResultsAge, sex, visual acuity, and health status had no significant correlation or association with the Rasch-transformed score. Patients who received bilateral corneal grafts were significantly less able socioemotionally than those with unilateral graft. Patients who became unemployed or retired after transplantation were also significantly less able in both visual functioning and socioemotional status.ConclusionCorneal transplant recipients had a decreased vision-related quality of life as demonstrated by the NEI VFQ-25. Apart from anatomical success and visual acuity, ophthalmologists should also consider other aspects of visual outcome. In particular, those who received bilateral grafts require more attention. Employment programmes should be part of corneal transplantation rehabilitation planning.     

Relationship between vision-related quality of life and different types of existing visual fields in Japanese patients

To investigate the vision-related quality of life (VRQOL) in relation to the type of existing visual field (EVF) in the presence of visual field defect. We evaluated the VRQOL of 95 patients by using Visual Function Questionnaire-25 (NEI VFQ-25). Patients fulfilled the following criteria: (1) they underwent a Goldmann perimetry (GP) test within 3?months of the initial visit, (2) the results of the GP test could be classified into three categories, and (3) the best-corrected decimal visual acuity (VA) was?≤0.3. The EVF was assessed by composite measurement of both eyes for the V-4e or I-4e isopters, as obtained using the GP test. We compared the VFQ-25 scores between three groups: (1) the “center and peripheral” group in which the EVF of the V-4e area was >30o and the I-4e area was <30o, (2) the “central VF” group in which the EVF of the V-4e area was <20o, and (3) the “central VF loss” group in which the central scotoma was >5o and the EVF of the V-4e area was >30o in peripheral vision. There were significant differences between the three groups (P?=?0.02, ANOVA). The total score of the “central VF loss” group was significantly lower than those of the “center and peripheral” and “central VF” groups. The central vision influenced the VRQOL to a greater extent than peripheral vision.     

Vision-related quality of life and visual function after retinal detachment surgery

PURPOSE: To compare the vision-related quality of life (VR QOL) after rhegmatogenous retinal detachment (RD) surgery with that of normal controls and to investigate the relationship between the VR QOL and visual function after surgery for RD. DESIGN: Prospective, consecutive, comparative case series. METHODS: The 25-Item National Eye Institute Visual Function Questionnaire (VFQ-25) was self-administered by 51 RD patients at six months after surgery. Among the patients with RD, 33 underwent pars plana vitrectomy and 18 received scleral buckling. We examined the logarithm of the minimum angle of resolution (logMAR) best-corrected visual acuity (BCVA), contrast sensitivity with the CSV-1000E (Vector Vision Co, Greenville, Ohio, USA), and low-contrast visual acuity (VA) with the CSV-1000LanC10% (Vector Vision Co). From the data obtained by CSV-1000E, the area under the log contrast sensitivity function (AULCSF) was calculated. The VFQ-25 also was administered to the 46 age-matched normal controls. RESULTS: The VFQ-25 composite score and the subscales associated with near activities, mental health, dependency, and peripheral vision were significantly lower in the RD group than in the normal controls (P < .05). The VFQ-25 composite score significantly correlated with AULCSF (r = 0.354; P < .05) and low-contrast VA (r = -0.475; P < 0.001), whereas there was no correlation between the VFQ-25 composite score and logMAR BCVA (r = 0.172; P = .229). CONCLUSIONS: The VR QOL is significantly impaired in patients after surgery for RD. The disturbance in VR QOL was significantly associated with deterioration of postoperative contrast sensitivity.     

Quality of life in a prospective,randomised pilot-trial of photodynamic therapy versus full macular translocation in treatment of neovascular age-related macular degeneration — a report of 1 year results

PURPOSE: To assess visual function and its effects on vision-targeted, health-related quality of life (QOL) of patients with neovascular age-related macular degeneration (AMD) treated with photodynamic therapy (PDT) or full macular translocation (FMT). METHODS: Fifty patients with predominantly classic subfoveal choroidal neovascularisation (CNV) secondary to AMD were randomised to PDT or FMT. To test the vision-targeted QOL, the 39-item National Eye Institute Visual Function Questionnaire (NEI-VFQ-25 plus supplement) was administered prior to and 1 year after therapy. The change of vision-related QOL at 1 year in comparison to baseline was defined as primary end point. RESULTS: The vision-related subscales showed a stabilisation or even higher mean scores at 1 year in both treatment groups. A significant improvement in the quality of the subject's vision-related subscales was only observed after FMT correlating with a more frequent increase in visual acuity. Comparing the results of the QOL scores after 1 year, the improvement of the subscale scores general vision (p = 0.03), mental health (p = 0.02) and dependency (p = 0.03) were significantly higher in the FMT arm. CONCLUSIONS: FMT and PDT can achieve a stabilisation in vision-related QOL, in which FMT was superior to the PDT after 1 year. The discrepancy between the amount of patients with an increased visual acuity after FMT and a moderate improvement in QOL might be caused by the onset of complications related to this surgical procedure. Besides visual acuity, the impact of therapy-related complications has to be taken into consideration when evaluating new therapeutic concepts in exudative AMD.     

Vision-related quality-of-life in Jamaican glaucoma patients at Kingston Public Hospital

AIM: To determine the vision-related quality-of-life of glaucoma patients and the association between clinical and socioeconomic factors, and vision-related quality-of-life. METHODS: This was a cross-sectional study. Consecutive patients with glaucoma were interviewed using a modified 25-item National Eye Institute Visual Function Questionnaire (VFQ-25) by a single interviewer. Statistical analysis was done to find associations between patient variables and vision-related quality-of-life scores. Confidentiality and anonymity were maintained. RESULTS: Ninety-six participants were recruited in the study. There were 44 males and the mean age for males and females was 65.7 and 69.5y, respectively. The mean composite score was 71.2 (with a maximum possible score of 100), with the highest mean score in the colour vision subscale (89.8) and the lowest mean score in the driving subscale (34.0). Worse visual acuity (P<0.001), longer duration of glaucoma (P<0.001) and higher number of glaucoma medications (P<0.001) were associated with a worse composite score. Female participants and those who lived in urban areas had significantly better scores than male participants (P=0.002) and those who lived in rural areas (P=0.017), respectively. CONCLUSION: The vision-related quality-of-life in Jamaican glaucoma patients is comparable to that of glaucoma patients in the Barbados Eye Study and other international studies using the VFQ-25 questionnaire. Worse quality-of-life scores are associated with poorer visual acuity, longer duration of glaucoma, more glaucoma medications, and sociodemographic factors such as male gender and rural residence.     

Determinants of Patient Satisfaction with Photodynamic Therapy for Neovascular Age-related Macular Degeneration or Polypoidal Choroidal Vasculopathy

Purpose

To evaluate the determinants of patient satisfaction with photodynamic therapy (PDT) for neovascular age-related macular degeneration (AMD) or polypoidal choroidal vasculopathy (PCV).

Methods

Questionnaires were mailed to 69 patients who had undergone PDT for AMD or PCV at the Kobe City General Hospital. The questionnaire considered the following parameters: subjective change in visual acuity, subjective change in the relative scotoma in central vision, subjective change in visual distortion, and patient satisfaction with PDT scored on a 100-point scale.

Results

Nine patients (14%) reported their subjective visual acuity change as “significantly improved” and 21 (32%) as “slightly improved”; 18 (27%) reported “no change”; 12 (18%) reported their visual acuity as “slightly worsened”; and 6 (9%) as “significantly worsened.” Subjective change in the central scotoma was reported improved in 43 patients (64%) and visual distortion had improved subjectively in 31 patients (47%). The satisfaction score was 59 ± 25 in patients who had undergone PDT for AMD and 75 ± 24 in those with PCV. Not only the visual acuity change but also the subjective change in central scotoma and visual distortion correlated significantly with the satisfaction score.

Conclusions

More patients who have undergone PDT for AMD or PCV perceive improvement in central scotoma and visual distortion than in visual acuity. Since these subjective changes correlated significantly with the satisfaction score, subjective change in central scotoma and visual distortion, in addition to visual acuity, should be taken into account in evaluating the benefits of PDT.?Jpn J Ophthalmol 2007;51:368–374 © Japanese Ophthalmological Society 2007

A prospective multicenter clinical trial to evaluate the safety and effectiveness of the implantable miniature telescope

PURPOSE: To evaluate the safety and preliminary efficacy of a novel visual prosthetic device, the Implantable Miniature Telescope, IMT (by Dr Isaac Lipshitz) (IMT), in a phase I trial in patients with significant bilateral central vision impairment from late-stage age-related macular degeneration (AMD). The IMT is designed to reduce the relative size of the scotoma by rendering enlarged (threefold) central visual field images over the central and peripheral retina. DESIGN: Prospective, multicenter, open-label clinical trial. METHODS: In this prospective, multicenter phase I trial, 14 patients aged 60 or older with bilateral geographic atrophy or disciform scar AMD, cataract, and best-corrected visual acuity (BCVA) between 20/80 and 20/400 had an IMT implanted in one eye. Distance and near BCVA, endothelial cell density, and quality of life, measured as activities of daily life (ADL), were evaluated preoperatively and postoperatively. RESULTS: At 12 months, 10 (77%) of 13 patients gained 2 more lines of either distance or near BCVA, and eight (62%) of 13 patients gained 3 or more lines in either distance or near BCVA. Mean endothelial cell density decreased by 13%. All adverse events resolved without sequelae. ADL scores improved in the majority of patients. CONCLUSION: The results of this phase I trial support further evaluation of the IMT in a larger study population with late-stage AMD. A phase II/III trial is in progress.     

Pattern visual evoked cortical potentials predict postoperative visual acuity after cataract surgery in patients with glaucoma

Visual acuity after cataract surgery in patients with glaucoma cannot be predicted accurately. We studied preoperative recordings of pattern visual evoked cortical potentials (PVECPs) to evaluate postoperative vision in patients with glaucoma and cataract. Fifty patients with glaucoma and no cataract and 31 patients with glaucoma and cataract who underwent phacoemulsification were included in this study. Age and P100 component significantly correlated with postoperative visual acuity with multiple linear regression analysis. A significantly greater number of patients with glaucoma, cataract, and a P100 component preoperatively showed a visual acuity of 0.7 or better postoperatively, as compared to those without a P100 component. PVECP before cataract surgery was able to predict postoperative good visual acuity in patients with glaucoma and cataract.     

Visual acuity and quality of life in patients with cataract in Doumen County, China.

PURPOSE: To evaluate the effectiveness of cataract surgery in achieving sight restoration and vision-related quality-of-life (QOL) in patients from rural southern China. DESIGN: Population-based, cross-sectional study. PARTICIPANTS: A total of 109 cataract operated persons (152 eyes) and 654 unoperated persons. METHODS: Cluster sampling was used in identifying a random sample of 5342 persons 50 years of age and older for visual acuity and eye examinations. Visual functioning (VF) and QOL questionnaires were administered to aphakic and pseudophakic individuals, unoperated persons with presenting visual acuity less than 0.10 in either eye, and a sample of those with normal vision. MAIN OUTCOME MEASURES: Distance visual acuity, VF, and QOL questionnaire scores. RESULTS: Among the cataract operated participants, 43 (39.4%) were bilaterally operated on, 32.1% had presenting visual acuity less than 0.10 in both eyes with 8.3% greater than or equal to 0.32 in both eyes. Of operated eyes, 52.6% presented with visual acuity less than 0.10, 23.7% greater than or equal to 0.32; with best correction, the corresponding percentages were 21.1% and 42.1%. Uncorrectable aphakia due to surgical complications was common. In a multivariate regression model, better visual acuity outcomes were associated with higher level surgeon practice settings and recent surgery. On a 0 to 100 scale, mean VF and QOL scores for the cataract operated population were 41.6 and 54.5, respectively. Mean scores ranged from 84.4 and 93.4, respectively, for the unoperated persons with normal vision, to 14.6 and 31.2, respectively, for those with visual acuity less than 0.05 in both eyes. The VF and QOL scores were closely correlated with presenting visual acuity in both cataract operated and unoperated populations (r = 0.49-0.64). Scores among the cataract operated population were not influenced by age, gender, or education level. Among the unoperated population, lack of education was associated with lower VF and QOL scores (P = 0.017 and P = 0.005, respectively), and older age was associated with lower QOL scores (P < 0.001). CONCLUSION: Patients in rural southern China are not realizing the full sight-restoring potential of modern-day cataract surgery. Remedial efforts are needed to improve the performance of local eye surgeons.     

Exudative age-related macular degeneration or Best vitelliform macular dystrophy?--A case report

PURPOSE: To report a case of Best vitelliform macular dystrophy referred to the Department Ophthalmology in Krakow with a diagnosis of exudative age-related macular degeneration (AMD). MATERIALS AND METHODS: 70-years old man was diagnosed in our clinic because of a two years history of slow, progressive visual acuity worsening in both eyes with the presence of metamorphopsia. The basic ophthalmic examination was performed with additional diagnostic methods including: colour vision test (Panel D-15), Amsler grid test, contrast sensitivity test (Pelli-Robson chart), fluorescein angiography (FA), indocyanine green angiography (ICGA), electroretinogram (ERG), electrooculogram (EOG) and optical coherence tomography (OCT). RESULTS: Visual acuity in the right eye was: 0.16 and in the left: 0.25. Amsler grid test revealed the presence of bilateral mild etamorphopsia with the relative central scotoma. Pelli-Robson test showed decreased contrast sensitivity perception in both eyes; PO > LO. On fundoscopy in macula of both eyes the symmetrical round, elevated lesions of 1.5 dd with the meniscus of subretinal creamy-yellow masses were present. The early frames of FA showed the presence of round lesions with distinct borders, unchanged in size and shape throught the examination, hypofluorescent in the lower and hyperfluorescent in the upper half of the lesions. Late frames of FA revealed the irregular hyperfluorescence also in lower aspects of the lesions. ICGA showed: round hypofluorescent lesions with isofluorescence in the upper part of the lesions. ERG--revealed no pathology, EOG--showed decreased light response and depressed Arden ratio in both eyes. OCT demonstrated hiperreflectivity of the retinal pigment epithelium with elevation of retina and deletion of the foveolar depression in both eyes. CONCLUSIONS: Based on the results of performed tests the diagnosis of the Best vitelliform macular dystrophy was established. In some cases various pathologies involving the macula may mimic the exudative AMD. The basic ophthalmic examination supported by additional diagnostic methods allow to establish the definitive diagnosis in most cases of macular disorders.
