“…This differs from findings from developed countries where even mild VI has been found to be associated with poor vision-specific functioning and VRQoL. 38,39 This finding reflects the present protocol for cataract surgery referral in developing or transitional countries such as India, where priority is given to patients with at least moderate to severe VI. 40 The decision of patients to accept recom-mended cataract surgery is based on a complex set of factors, 41,42 including individually perceived levels of vision-specific functioning and quality of life, 43 which may not be affected until VI has progressed to the more severe stages.…”

“…Detailed information regarding the Rasch results and the impact of visual impairment and ocular conditions on visual functioning as measured with the VF-14 has been reported elsewhere. 21 Both measures (i.e., the LLQ-23 and the VF-14) were highly correlated (Pearson correlation coefficient 0.701, P Ͻ 0.001).…”

“…It has been well established that poor vision is associated with depression. 1422–25 This may be exacerbated in developing countries where the visually impaired may be seen as a socioeconomic burden and there are fewer resources to aid them. Previous studies have suggested an increase in impact of visual disability in developing countries compared with developed countries.…”

Risk factors for low vision related functioning in the Mycotic Ulcer Treatment Trial: a randomised trial comparing natamycin with voriconazole

et al. 2015

Background/aims The Mycotic Ulcer Treatment Trial I (MUTT I) was a double-masked, multicentre, randomised controlled trial, which found that topical natamycin is superior to voriconazole for the treatment of filamentous fungal corneal ulcers. In this study, we determine risk factors for low vision-related quality of life in patients with fungal keratitis. Methods The Indian visual function questionnaire (IND-VFQ) was administered to MUTT I study participants at 3 months. Associations between patient and ulcer characteristics and IND-VFQ subscale score were assessed using generalised estimating equations. Results 323 patients were enrolled in the trial, and 292 (90.4%) completed the IND-VFQ at 3 months. Out of a total possible score of 100, the average VFQ score for all participants was 81.3 (range 0–100, SD 23.6). After correcting for treatment arm, each logMAR line of worse baseline visual acuity in the affected eye resulted in an average 1.2 points decrease on VFQ at 3 months (95% CI −1.8 to 0.6, p<0.001). Those who required therapeutic penetrating keratoplasty had an average of 25.2 points decrease on VFQ after correcting for treatment arm (95% CI −31.8 to −18.5, p<0.001). Study participants who were unemployed had on average 28.5 points decrease on VFQ (95% CI −46.9 to −10.2, p=0.002) after correcting for treatment arm. Conclusions Monocular vision loss from corneal opacity due to fungal keratitis reduced vision-related quality of life. Given the relatively high worldwide burden of corneal opacity, improving treatment outcomes of corneal infections should be a public health priority. Trial registration number Clinicaltrials.gov Identifier: NCT00996736.

The impact of the severity of vision loss on vision-specific functioning in a German outpatient population — an observational study

Abstract: Using a psychometrically valid German-translated VF-14, even mild vision impairment was independently associated with poor visual functioning. These findings reinforce the importance of early preventative and rehabilitative efforts to prevent longitudinal deterioration in vision loss.
