“…PROGRAMME 2 (1987PROGRAMME 2 ( -1988 The Canon CR5-45NM non-mydriatic retinal camera became available in the mid-1980s (Optimed, Lane Cove, NSW, Australia) and was trialled extensively in the Pilbara region of Western Australia both for mechanical robustness and as a replacement for direct/indirect ophthalmoscopy. 11 It was recognized early that mydriatic agents were necessary to maximize the quality of photographs. Tropicamide 1% and phenylephrine 2.5% improved photographic quality dramatically as visualized on Polaroid™ prints.…”

Western Australia has a large landmass and low population density. Dating back to the 1970s and even today, specialist medical services are often lacking or non-existent outside of Perth, the capital city. Diabetes has always been a major health problem, particularly in the Australian Aboriginal community. In conjunction with the Lions Save Sight Foundation and Diabetes Foundation of Western Australia a diabetic screening programme was initiated in 1978 for rural and remote diabetics. The programme aimed to screen for diabetic retinopathy, educate diabetics, medical and paramedical personnel and to arrange treatment for sight threatening eye disease. Eye screening continues to date although the role of the Lions Eye Institute has changed from programme initiator to reading centre and teaching unit, and continues to evolve with changing technologies.

“…DR screening has been advanced through teleophthalmlogy service to automated grading system in the developed world (Moss et al, 1985;Diamond et al, 1998;Saari et al, 2004;Klein et al, 1985;Lin et al, 2002). Despite these advances in the high income countries, in Nepal, awareness on DR, DR screening, referral and treatment service are still lacking far behind (Thapa et al, 2012;2015).…”

“…Despite some awareness, limited access for DR screening and limited vitreo-retinal services are the major barriers for service utilization in Nepal (Thapa et al, 2012(Thapa et al, , 2014. DR could be screened using various techniques such as direct and indirect ophthalmoscopy, and digital fundus photography (Moss et al, 1985;Diamond et al 1998;Saari et al 2004;Klein et al 1985;Lin et al 2002). There is further development in DR screening with the advancement in teleophthalmology and automated grading system (Perumalsamy et al 2007;Gupta et al 2013).…”

Agreement on diabetic retinopathy grading in fundus photographs by allied ophthalmic personnel as compared to ophthalmologist at a community setting in Nepal

Introduction: Diabetic retinopathy (DR) is the emerging cause of blindness in the developing world. Timely detection of DR could save vision from its avoidable blinding condition. Objective: To assess the accuracy of DR grading in fundus photographs by the allied ophthalmic personnel (AOP) as compared to ophthalmologist at a community setting in Nepal. Materials and methods: Fundus photographs of known diabetes subjects attending for DR screening were graded by two groups of AOP and ophthalmologist. Agreement for DR grading by the AOP versus ophthalmologist was assessed using kappa coefficient (k). Results: Fundus photographs of 864 eyes of 435 subjects with diabetes were evaluated in the study. The agreement was substantial for detection of normal versus abnormal retina by both the AOP 1 and AOP 2. For normal versus abnormal macula, the agreement was substantial for AOP 1 and moderate for AOP 2. The agreement for grading macular exudates, retinal hemorrhage, venous beading ranged from moderate to substantial for both the AOPs. There was overall substantial agreement for diagnosing cases with or without DR and CSME by both the AOP 1 and AOP 2. The agreement ranged from fair to moderate for diagnosing other stages of NPDR by both the AOPs. Conclusion: Allied ophthalmic personnel with training could be a first level DR screener and referral of vision threatening DR. Three out of five diabetics could be managed at community level and thus reduce work load of ophthalmologist. This DR screening modality can be useful in other resource limited countries.

“…These are designed with an infrared focusing system that promotes physiologic dilation in a darkened room, making them simple to operate [5]. Imaging with nonmydriatic cameras has demonstrated higher sensitivity and specificity than ophthalmic consultation [6]. Although they may improve patient experience and eliminate the need to wait for dilation, they are susceptible to media opacity (such as cataract) and have a smaller field of view, so mydriatic cameras remain the instrument of choice especially if the peripheral retina requires imaging [5].…”

A comprehensive review of diagnostic imaging technologies to evaluate the retina and the optic disk

2015

Ophthalmic imaging has undergone a revolution over the past 20 years with increasingly efficient and high-definition modalities now available. The use of wide-field retinal angiography, fundus autofluorescence, state-of-the-art spectral domain, and enhanced depth imaging optical coherence tomography has proven to be effective in this field. This comprehensive review is devoted to retinal and optic disk imaging modalities and their clinical implications. It is based on the published literature in the field of ophthalmic imaging with a focus on recent advances. Ophthalmic imaging plays a crucial role in the management of patients with both isolated retinal disease and systemic diseases with ocular manifestations. Evolving technology enables imaging of ocular disease in vivo, facilitating objective assessment of disease progression and response to treatment. These latest technical improvements in ophthalmic imaging are now a part of standard ophthalmic assessment in academic centers and most private practices. In the coming years, further advances may improve diagnostic sensitivity and enable cost-effective screening of large populations.

Non‐mydriatic fundus photography: A viable alternative to fundoscopy for identification of diabetic retinopathy in an Aboriginal population in rural Western Australia?

Abstract: The Canon CR5-45NM non-mydriatic fundus camera was relatively good at identifying diabetic retinopathy and could usefully be applied within a screening programme for treatable disease within this population.
