Welcoming teleretinography into diabetes integrated care.

Integrated Care (IC) is a perfect fit for people with diabetes. Fundus examination (FE) is a disease marker for diabetologists and identifies potentially blinding complications (Diabetic Retinopathy, DR). In our Diabetes Clinic (DC) in Pescara, Italy, FE is possibly provided with telemedicine in same day as other exams, avoiding it to be a standalone clinical one; images taken with a retinal digital camera are graded by a remote ophthalmologist within a shared Electronic Health Record (EHR), immediately readable by other stakeholders; a dedicated care path to the Eye Clinic, University of Chieti-Pescara is provided for urgent cases. Personnel's worktime shortening allows gaining time for ophthalmologists' eye examinations in outpatient settings and other stakeholders' work in the DC. The need for a DR digital screening system is growing worldwide: our experience confirms the ease of implementation, and the advantage of sharing clinical data with all stakeholders when working within an EHR, aiming to optimize an IC effective system.

Why Miss the Chance? Incidental Findings while Telescreening for Diabetic Retinopathy.

PURPOSE: To report on incidental pathological findings met while screening for Diabetic Retinopathy (DR) in Diabetes Clinics (DC) by ophthalmologist-graded digital fundus imaging. METHODS: At the DC of Pescara (central Italy), for 3,859 eyes of 1,930 consecutive patients having not undergone fundus examination in the last year, two mydriatic fundus digital images, taken with a CenterVue DRS Digital Retinal Camera, were sent along with Best Corrected Visual Acuity, on a "store-and-forward" basis, to an ophthalmologist trained in DR screening, and graded according to the UK Diabetic Eye Screening Programme. Incidental fundus abnormalities other than DR were reported. RESULTS: No adverse event to mydriasis was reported. One hundred and eighty eyes (4.66%) were ungradable. Among the 3,679 gradable ones, 1,105 (30.04%) showed different degrees of DR (R1 to R3), and 126 (3.42%) maculopathy (M1). Any Age-Related Macular Degeneration was present in 387 eyes (10.52%), any optic disc and parapapillary area features suspect for glaucoma in 562 eyes (15.27%), any hypertensive retinopathy in 1,263 eyes (34.33%), vitreoretinal interface disease in 252 eyes (6.84%), myopic choroidopathy in 92 eyes (2.50%), disc pallor in 31 eyes (0.84%). Mean time was 5 min for screening, 2 min for grading. CONCLUSION: Teleretinography is a well-established, cost-effective procedure in DR screening. Along with increased attendance, locating a digital camera in a DC with a retina-specialist grader results in finding fundus pathologies also beyond DR, very similarly to fundus examination in an outpatient ophthalmic setting.

Vision-related quality of life and locus of control in type 1 diabetes: a multicenter observational study.

AIMS: Diabetic retinopathy remains asymptomatic until its late stages but remains a leading cause of vision impairment and blindness. We studied quality of life and the ability to deal with the discomfort deriving from the presence of a chronic disease in patients with type 1 diabetes and different stages of retinopathy. METHODS: Multicenter collaborative observational study involving nine centers screening for retinopathy in different areas of Italy. The National Eye Institute 25-item visual functioning questionnaire and the locus of control tool were administered to 449 people with type 1 diabetes between February 2016 and March 2018. Socio-demographic and clinical data were collected. RESULTS: On multivariable analysis, severe retinopathy is associated with worse scores for general vision, ocular pain, near vision activities, distance vision activities, driving, color vision, peripheral vision and lower values of internal control, independently of visual acuity. Women had a perception of worse general health, distance vision activities and driving, and lower internal control and trust in others. Worse scores for visual-specific social functioning, visual-specific mental health, visual-specific role difficulties, visual-specific dependency and peripheral vision were associated with higher HbA1c levels. Fatalism increased with rising HbA1c levels. CONCLUSIONS: These results confirm that a gap exists between patients' knowledge and expectations on retinopathy and providers' expertise and assumptions. To bridge this gap, patient-centered education and engaging approaches may be more effective than simple information given during consultations.

[Blindness and social security in Italy: critical issues and proposals.] / La cecità civile in Italia: criticità e proposte.

In Italy, blindness and low vision are ruled by Law 138/2001: two categories of blindness (corresponding to the one in the current WHO classification), receiving economical remuneration, and three categories of low vision, not directly remunerated. The problem ensues that low vision patients, who better gain from rehabilitation, have no economical contribution to undergo such care pathways; moreover, in Italy the evaluation has not yet shifted from "visual function" to "functional vision", thus lacking a holistic evaluation of visual dysfunction impact on the patient's daily life skills. To quantify the visual function of the examinee, only subjective performance (visual acuity and/or visual field) is evaluated in accordance with Law 138/2001, thus paving the way to malingerers: the "false blinds" phenomenon has recently reached the media. The Authors suggest that a correlation between the individual anatomical picture of the pathology/ies and the visual performance, obtained in patients with similar lesions undergoing controlled clinical studies reported in the ophthalmological literature, could offer more objective values to quantify the visual function.

Teleretinography into diabetes integrated care: an Italian experience.

INTRODUCTION: Integrated care, by allowing information exchange among health professionals, improves outcomes and favours a reduction in hospital admission in diabetes. Retinal complications can be sight-threatening, and diabetic patients often miss the suggested yearly clinical examination. METHODS: Teleretinography can be easily performed in patients attending Diabetes Clinics: images are sent to a remote ophthalmologist, grading and instructions are received and forwarded to General Practitioners by a dedicated software. RESULTS: We here report the results of teleretinography performed in our Diabetes Clinic in 362 patients missing the yearly fundus examination: 253 patients showed no diabetic retinopathy, 86 a mild form, and 23 needed referral to hospital settings. CONCLUSIONS: Teleretinography is a user-friendly, time-saving and cost-effective technique, easily integrable into integrated care, allowing a better adherence to guidelines.

Screening eye diseases in babies: an Italian experience on 5000 healthy, consecutive newborns.

INTRODUCTION: Visual performance of eyes with congenital pathologies is conditioned by an early diagnosis. Families having problems in accessing health services risk to delay or miss both an early diagnosis and an early treatment and amblyopia (lazy eye) prevention. METHODS: In our hospital, all full-term, healthy newborns are thoroughly examined by an ophthalmologist in the maternal ward, 1 to 3 days after birth. RESULTS: Among the first 5000 newborns examined, a high incidence of congenital pathologies compared to international literature was reported, with differences between Caucasians and non-Caucasians. CONCLUSION: Performing an early in-hospital thorough eye examination in all newborns as a screening would be an effective way to miss none and to start an early and effective pathway of disease treatment.

Biocompatibility assessment of silicone oil and perfluorocarbon liquids used in retinal reattachment surgery in rat retinal cultures.

The effects of silicone oil and perfluorocarbon liquids used in retinal reattachment surgery were studied in vitro using rat retinal cultures seeded on microporous inserts. These inserts allow the cell layer to be in contact with the material to be tested on the apical side and with the nutrient medium on the basal side. The materials tested were silicone oil, the perfluorocarbons perfluorophenanthrene and perfluoroctane, and hydroxypropylmethylcellulose. Perfluorophenanthrene, the heaviest of the compounds, induced a very precocious detachment of the cell layer. All the other tested biomaterials were compatible with cell survival and did not alter the structural organization of the retinal cultures, as revealed by scanning electron microscopy. By immunocytochemical techniques we evaluated the cell composition and the differentiation state of each of the cultures. In both control and treated samples, neuronal cells were well preserved. The expression of microtubule-associated protein 2, a marker of differentiated neuronal cytoskeleton, was not affected. Amacrine neurons, immunolabeled for gamma-aminobutyric acid, still were detectable after treatment. Synapses, marked by immunoreactivity for synapthophysin, were equally preserved. Vimentin-positive glial cells did not show modifications. The apoptotic rate, as determined by the terminal transferase-mediated dUTP-biotin nick end-labeling assay, was similar in treated and control samples. The results confirm that the use of biomaterials with a specific gravity close to intraocular fluids is compatible with retinal cell survival and differentiation in vitro.
