Fluorescein angiography

Fluorescein angiography is a diagnostic test that aids visualization of the blood circulation in the retina and choroid. Fluorescein is a water-soluble dye that is injected into a vein in the patient's arm. It travels through the blood vessels of the body thereby aiding multiple photographing of the retina. The images obtained help in detecting any swelling or leakage in the blood vessels. The patient's eyes are dilated with mydriatic eye drops so that photographs of the inside of the eye can be taken.

Some patients may notice skin rash, itching or allergic reaction to the dye. Nausea or vomiting may be noticed. But this non-invasive test can usually be safely repeated. Abnormal results of fluorescein angiography test may indicate diabetic retinopathy, macular degeneration, or cancer. Ischaemia or oedema in the retina circulation can be detected with the help of fluorescein angiography

Opthalmoscope

An opthalmoscope is used to examine the retina and vitreous. Ophthalmoscopy aids visualization of the inside of the back of the eye including the retina, optic disc, choroid and blood vessels. It is often part of a routine eye examination. A direct opthalmoscope is used for viewing the central retina. It is hand-held and powered with a light source. The instrument has to be adjusted constantly to focus on different structures within the eye. The light can be intense and disturbing. An indirect ophthalmoscope aids in examining the entire retina. This instrument is attached to the doctor's head and allows a clear view of the retina with a special lens. The patient may feel uncomfortable due to the intense light and pressure from the instrument.

Opthalmoscopy is useful in detecting any changes in the retina due to diseases such as eye disease, diabetes, arteriosclerosis, high blood pressure or macular degeneration. Cataracts and other eye problems can be detected with an opthalmoscope.

The patient's eyes are dilated so as to allow a good view of the insides of the eye. Some patients develop allergic reaction, vomiting, nausea and dizziness. This test is conducted in a darkened room where the patient is asked to look ahead at a distant spot. The eyes must be held steady without blinking. The opthalmoscopy procedure may take just about 5 - 10 minutes.

Diet Plan

There are many diet plans around catering to various requirements. Food plays an important role in our lives. Understanding our body requirements and adapting our lifestyles with healthy food options that provide vital nutrition and energy can go a long way in maintaining good health. This has assumed more importance today on account of the deteriorating diet patterns, especially that of growing kids. Keep obesity, high cholesterol and other diseases such as anemia and osteoporosis at bay by choosing healthy food substitutes.

For example to keep Osteoporosis at bay, eating a calcium-rich diet can help. Including milk, particularly skimmed milk and low fat yogurt can help you build your calcium deposits. Spinach is a source of non-dairy calcium. Anemia is of particular concern to women, especially those who resort to dieting. Consuming meat, fish and poultry or leafy green vegetables, nuts and breakfast cereals can provide you with adequate iron.

Similarly Lutein is a pigment found in dark green leafy vegetables like spinach, collard greens, kale, mustard greens, and turnip greens, corn and egg yolks. Lutein as an antioxidant reduces the effects of free radicals. Lutein in adequate quantities in the diet can help ward off Macular Degeneration or MD , a condition in which the center of retina suffers permanent damage due to a number of causes - natural degradation triggered by ageing or by undue exposure to strong light. Another carotenoid, zeaxanthin again has similar beneficial effects on the eyes. In addition some studies have indicated that these carotenoids can also help prevent cataracts.
