ObjectivesVisual impairment is an important risk factor for fracture in the elderly population. Age-related macular degeneration (AMD) is the leading cause of irreversible visual impairment in elderly people. This study was conducted to explore the relationship between AMD and incident fractures in patients with osteoporosis (OS).DesignRetrospective analysis of Taiwan’s National Health Insurance Research Database (NHIRD).SettingA multicenter study conducted in Taiwan.Participants and controlsThe current study used the NHIRD in Taiwan between 1996 and 2011. A total of 13 584 and 54 336 patients with OS were enrolled in the AMD group and the non-AMD group, respectively.InterventionPatients with OS were included from the Taiwan’s NHIRD after exclusion, and each patient with AMD was matched for age, sex and comorbidities to four patients with non-AMD OS, who served as the control group. A Cox proportional hazard model was used for the multivariable analysis.Primary outcome measuresTransitions for OS to spine fracture, OS to hip fracture, OS to humero-radio-ulnar fracture and OS to death.ResultsThe risks of spine and hip fractures were significantly higher in the AMD group (HR=1.09, 95% CI=1.04 to 1.15, p<0.001; HR=1.18; 95% CI=1.08 to 1.30, p=0.001, respectively) than in the non-AMD group. The incidence of humero-radio-ulnar fracture between AMD and non-AMD individuals was similar (HR=0.98; 95% CI=0.90 to 1.06; p=0.599). However, the risk of death was higher in patients with OS with older age, male sex and all types of comorbidity (p<0.05), except for hyperthyroidism (p=0.200).ConclusionPatients with OS with AMD had a greater risk of spine and hip fractures than did patients without AMD.

General physicians have an essential role in preventing vision loss in older people. However, most vision-threatening eye disorders are initially asymptomatic and often go underdiagnosed. Therefore screening, early detection, and timely intervention are important in their management. The most common cause of visual impairment is uncorrected or undercorrected refractive error, followed by cataract, age-related macular degeneration, glaucoma, and diabetic retinopathy. Spectacles and cataract surgery can successfully restore sight for uncorrected refractive error and cataract, respectively. Visual impairment as a result of age-related macular degeneration, glaucoma, and diabetic retinopathy can be prevented with appropriate treatment if they are identified early enough. This chapter provides an overview of common age-related eye disease and visual impairment.

Purpose. Determining long-term effects of rheohaemapheresis on the dry form of age-related macular degeneration.Methods. This study evaluates 19 patients, average age of 67.6 years, treated with rheohaemapheresis and 18 patients, average age of 72.8 years, comprising the control group. Minimum follow up period was 3.5 years. Each treated patient received a series of 8 sessions of rheohaemapheresis of 1.5 plasma volumes within 10 weeks. We measured the drusenoid pigment epithelium detachment (DPED), best-corrected visual acuity (BCVA), electroretinography (ERG), and rheological parameters.Results. In the treatment group, the baseline BCVA was 0.74 (0.36–1.0) 95% CI and BCVA after 3.5 years was 0.79 (0.41–1.0) 95% CI (P=0.726). In the control group, the baseline BCVA was 0.71 (0.15–1.0) 95% CI and BCVA after 3.5 years decreased to 0.7 (0.32–0.87) 95% CI (P=0.031). Baseline DPED was 6.78 ± 3.79 mm2; after 3.5 years, it decreased to 4.13 ± 3.84 mm2(P<0.001). In the control group, the baseline DPED was 4.09 ± 3.48 mm2; after 3.5 years, it increased to 6.69 ± 4.2 mm2(P=0.001). We noted increasing levels of positive wave peaking at 50 milliseconds (P50) after treatment (P=0.022) and a stable amplitude of photopic responses of treated patients.Conclusion. Over the long term, rheohaemapheresis reduced the DPED, improved the function of photoreceptors, and prevented the decline of BCVA.

Aim. To evaluate the long-term effect of rheohemapheresis (RHF) treatment of age-related macular degeneration (AMD) on photoreceptor IS/OS junction status.Methods. In our study, we followed 24 patients with dry AMD and drusenoid retinal pigment epithelium detachment (DPED) for a period of more than 2.5 years. Twelve patients (22 eyes) were treated by RHF and 12 controls (18 eyes) were randomized. The treated group underwent 8 RHF standardized procedures. We evaluated best-corrected visual acuity, IS/OS junction status (SD OCT), and macular function (multifocal electroretinography) at baseline and at 2.5-year follow-up.Results. RHF caused a decrease of whole-blood viscosity/plasma viscosity at about 15/12%. BCVA of treated patients increased insignificantlyP=0.187from median 74.0 letters (56.2 to 81.3 letters) to median 79.0 letters (57.3 to 83.4 letters), but it decreased significantly from 74.0 letters (25.2 to 82.6 letters) to 72.5 letters (23.4 to 83.1 letters) in the control groupP=0.041. The mfERG responses in the region of eccentricity between 1.8° and 7° were significantly higher in treated patientsP=0.04.Conclusions. RHF contributed to sparing of photoreceptor IS/OS junction integrity in the fovea, which is assumed to be a predictive factor for preservation of visual acuity.
