Diabetes is a disease characterized by high levels of blood glucose. It is important to keep diabetes under control to avoid short- and long-term complications. Diabetes can affect vision due to the alterations it produces in the blood vessels of the retina. This is known as Diabetic Retinopathy (DR), which is one of the leading causes of impaired vision in developed countries. One of the complications of diabetic retinopathy is Diabetic Macular Edema (DME), which is the leading cause of vision loss in diabetic patients and can appear at any stage of diabetic retinopathy. This consists of the gradual accumulation of fluid in the macula, the most important area of the retina. The determination of diabetic macular oedema is very important for the retina. The determination of diabetic macular oedema is very important for adequate treatment of this condition. A variety of technological options are used for detecting diabetic retinopathy, although only the most sophisticated detect macular oedema, a complication that appears as a consequence of diabetic retinopathy and is one of the leading causes of blindness. The invention describes a portable system for detecting diabetic macular oedema by capturing a fundus image using a portable ophthalmoscope; said image is sent via wired or wireless means to an embedded system that has an algorithm based on artificial intelligence, which extracts information from the image and processes same to identify the presence of the condition being studied.

A fitting method for an astigmatic contact lens set and an associated astigmatic contact lens set. The astigmatic contact lens set includes an apodization monooptic lens for lower lenticular error correction and a toric lens for higher lenticular error correction. An astigmatic eye having a lenticular error greater than a higher specified lenticular error label focal power (e.g., gt; 1.25 diopter (D)) may be equipped with a non-apodized toric lens with a stabilization mechanism. However, astigmatic eyes having lenticular errors up to higher specified lenticular error label powers (e.g., < = 1.25 diopters (D)) may be equipped with apodized monocular lenses. The apodized monocular lens has an apodized distribution that reduces aberration to provide improved vision, so that a larger number of astigmatic patients up to higher lenticular error can achieve acceptable vision with the apodized monocular lens and improve comfort due to the absence of a stabilizing mechanism.
