Vision Rehabilitation

The purpose was to describe the patient characteristics, the prescribing trends and habits among the public health care optometrists who perform low vision rehabilitation in Norway. Data were collected using a questionnaire to gather background details of the optometrist, and a practice registration form to register patient characteristics and information about the low vision device(s) prescribed. Both forms were distributed to 44 public health care optometrists. A total of 30 questionnaires and 20 practice registration forms were returned. This included data for 147 patients with visual impairment. Moderate to severe visual impairment according to The World Health Organization (WHO)’s definition (visual acuity ≤ 6/18) was present in 82 (59%) of the patients. Three out of four (75%) patients did not have sufficient vision for reading. Distance visual acuity was improved with best optical correction in 39 (28%) of the patients compared to the presenting visual acuity. The most frequently prescribed optical devices for near and distance vision were hand magnifiers and filters/tinted lenses respectively. Optometrists play an important role in vision rehabilitation of older people attending the low vision services.  A number of the patients seen in low vision services are referred from non-eye care professionals and achieve improved vision with appropriate optical correction. Others are only mildly visually impaired with adequate optical correction alone. This indicates a potential to use general optometric practice as the first step for vision rehabilitation, as a number of people are only mildly visually impaired with adequate optical correction.

Introduction: Macula edema consists in one of the most common causes of visual impairment. Objective: To evaluate the safety and efficacy of continuous release of 0.7 mg dexamethasone (using implantable device) for treatment of macular edema. Methods: Cross-sectional observational study of 16 patients treated with 0.7 mg dexamethasone intraocular implant. Visual acuity, intraocular pressure and central macular thickness were recorded at baseline, 1-month and 3-month follow-up. Results: 15 eyes of 13 patients were included. Most eyes (n=9) improve visual acuity from baseline at 1-month follow-up; this improvement persisted through 3-monyh follow-up in six eyes. The central macular thickness decreased in the majority of the subjects at 1-month (n=12) and at 3-month (n=10) follow-up. Three eyes presented with elevated intraocular pressure. Conclusion: Dexamethasone implant can both reduce the risk of vision loss and improve anatomical features of macular edema due to several pathologies studied. This implant may be used safely and should be considered a therapeutic option to Brazilian Public Health System.

This paper presents the findings of a study to determine optometrists’ opinions on the presentation of ocular pathology and ametropia in patients wearing ready-made reading spectacles. Ninety-seven optometrists completed a questionnaire pertaining to ametropia and ocular diseases among these patients. The questionnaire contained information regarding patient demographics, ocular pathology, ocular ametropia and the regulatory and public health aspects of ready-made readers.Ninety-five percent of respondents stated that they had seen patients with ready-made readers in their practice and 62% of these stated that they had found the presence of ocular pathology in these patients. The pathologies most commonly reported as seen by practitioners were dry eye (86% of practitioners), cataracts (80%) and diabetic retinopathy (54%). In addition, 39% of practitioners reported seeing patients with anisometropia. The majority of practitioners (71%) stated that they sold ready-made readers in their practice. Sixty-three percentof practitioners indicated that they would be prepared to offer a service whereby a reduced consultation fee and a pair of ready-made readers could be incorporated into an indigent “package”. An overwhelming 88% of the practitioners felt that the sale of ready-made readers should be more regulated and 74% of practitioners felt that the Professional Board for Optometry and Dispensing Opticians should be responsible for monitoring their sale. The research suggests that wearers of ready-made readers should be screened for ocular pathology, reduced visual acuity and amblyopia. Current regulations should be tightened and a public awareness education campaign should be initiated. The use of ready-made reading spectacles, in deference to an eye examination by an optometrist, appears to be largely as a result of the perceived costs of pri-vate practice combined with ignorance and apathy

BackgroundFor treatment of neovascular age-related macular degeneration (nAMD), multiple intravitreal injections of drugs targeting vascular endothelial growth factors (VEGF) result in a high burden for patients and healthcare systems. Low-energy stereotactic radiotherapy (SRT) might reduce the anti-VEGF need. This study evaluated the long-term efficacy and safety of adjunct SRT to anti-VEGF injections in a treat-and-extend regimen in nAMD.Methods50 consecutive patients were followed 3 years after single-session SRT, a safety analysis including standardised study imaging, and a reading centre based image analysis was performed after 2 years.ResultsAfter increase from baseline (4.24±0.66 weeks) to 12 months (7.52±3.05 weeks, p<0.001), mean recurrence-free anti-VEGF treatment interval remained stable at 24 (7.40±3.17, p=0.746) and 36 months (6.89±3.00, p=0.175). Mean visual acuity change was −5.8±15.9 and −11.0±20.1 letters at 24 and 36 months, respectively. 36% of eyes showed microvascular abnormalities (MVAs) on colour fundus photography and/or fluoresceine angiography most frequently located in parafoveal inferior and nasal regions.ConclusionIn real life, low-energy SRT was associated with a reduced anti-VEGF injection frequency through year 3. However, due to an observed visual acuity reduction and remarkable number of MVAs, a close follow-up of these patients is recommended. The real-life use, optimal treatment schedule and dose should be rediscussed critically.

AbstractInadequate Ca intakes are a concern for global public health. In France, most dietary Ca is provided by dairy products: milks, fermented milks (mostly yogurts), dairy desserts and cheeses. The present dairy database (n 837) included milks (n 101), fermented milks, yogurts and other fresh dairy products (n 326), desserts (n 162) and a wide variety of cheeses (n 248). Energy and nutrient values were obtained from industry sources and the French national nutrient composition database. Retail prices were from Paris supermarkets. Products in each group were aggregated into twenty-one categories using clustering analyses. The costs in energy (kJ (kcal)), euros (€), and in SFA, added sugar and Na (defined here as nutrients to LIMit) associated with providing 120 mg of Ca (equivalent to 15 % daily value (15 % DV)) were calculated for each product group and category. The milk group supplied Ca at the lowest energy, monetary and LIM cost. Fresh plain and ‘light’ yogurts and fermented milks were next, followed by sweetened yogurts and flavoured milks. Light dairy desserts provided Ca with relatively few energy but were more expensive. Cheeses were a heterogeneous group. Hard cheeses (Comté) provided the most Ca per serving. Semi-hard cheeses (Camembert) and cream and blue cheeses (Roquefort) provided Ca at a cost comparable with sweetened yogurts and flavoured milks. Double cream, soft and goat cheeses were not optimal Ca sources. New value metrics can help identify affordable dairy foods that provide Ca without excessive energy or nutrients to limit. These conditions were satisfied by a wide variety of dairy products in France.

Purpose. To evaluate the effectiveness of surgical treatment of idiopathic macular hole in the conditions of the Regional State ophthalmologic clinical hospital of Public Health Ministry of Udmurt Republic. Methods. The study included 32 patients (32 eyes), 30 women, 2 men, aged 54 to 73 years with idiopathic macular hole. The patients were divided into three groups: the first – 8 people with a small diameter of macular hole (206.1±31.1 microns), the second – 8 people with a medium diameter of macular hole (333.5±53.6 microns), the third – 16 people with a large diameter of macular hole (564.7±96.6 microns). All of them underwent a 25-gauge vitrectomy with removal of the internal limiting membrane, drainage of the macular opening, instillation of 1-2 drops of platelet-rich autoplasma and subsequent air tamponade of the vitreal cavity. At the same time, the patients occupied a forced position of the body face down for the next 2 hours after the operation. Examinations were carried out before surgical treatment, at discharge from the hospital, 1 month and 1 year after the operation. Results. In the postoperative period, the closure of the macular hole was noted in 100 % of cases. In the first group, the visual acuity improved from 0.09±0.04 to 0.2±0.1 after 1 month and became 0.24±0.21 after 1 year after surgery (p < 0.05, U-test). In the second group, the visual acuity improved from 0.12±0.08 to 0.25±0.14 after 1 month and became 0.35±0.22 after 1 year after surgery (p<0.05, U-test). In the third group, the visual acuity improved from 0.08±0.05 to 0.13±0.05 after 1 month and became 0.16±0.15 after 1 year after surgery (p < 0.05, U-test). Conclusion. The results obtained indicate 100% effectiveness of the applied method of surgical treatment of macular hole, but to achieve even better results, it is necessary to search for new methods of treatment without removing the ILM. Key words: idiopathic macular hole, platelet-rich autoplasma, vitrectomy.
