This type of doctor specializes in the: Medical and surgical care of the eyes and visual system Prevention of eye disease and injury Macular Degeneration Screening and Diagnosis To help diagnose macular degeneration, an ophthalmologist or optometrist will perform a comprehensive eye exam that may include the following tests: Autofluorescence Eye care professionals use autofluorescence photos to study the retina and measure the progression of geographic atrophy in patients with advanced, dry AMD.

Doctors can use this technique to monitor the retinal pigment epithelium RPE , the deepest layer of the retina: RPE cells maintain the function of the light-sensitive cells in the retina the cells that allow us to see. In dry AMD, the RPE layer of the retina thins, eventually causing the death of light-sensitive cells and leading to visual impairment.

What is Macular Degeneration and Age-Related Macular Degeneration (AMD)?

This process is called geographic atrophy, and it occurs in the advanced stage of dry AMD. Dilated Eye Exam To view the back of your retina, the doctor dilates the pupils with eye drops. Fundoscopy or Ophthalmoscopy After dilating the pupil, the doctor aims a bright beam of light into the eye to check for problems in these parts of the eye: Retina: Nerve layer lining the back of the eye Choroid: Thin layer connecting blood vessels and nerves to other parts of the eye Blood vessels Optic disk: Small, circular area in the back eye where the optic nerve connects to the retina Visual Acuity Test or Eye Chart Test This test measures your sight from various distances.

Fundus Photography After dilating the pupil, the doctor focuses light through the cornea, pupil, and lens. He or she uses a customized camera to photograph the back of the eye to look for signs of disease in the: Retina Macula: Specialized center of the retina, responsible for sight in the center of vision Optic nerve: Nerve that carries sensory information related to vision from the retina to the brain Fundus photography helps the doctor measure changes between visits.

Fluorescein Angiography If your doctor suspects that you may have the wet type of AMD, he or she may conduct this test to detect leaking blood vessels. Tonometry This test measures the pressure inside the eye. During an eye exam, the eye care professional may ask you to look at an Amsler grid to check for AMD: The grid resembles graph paper in which straight lines intersect at right angles. You cover one eye and stare at a black dot in the center of the grid. While staring at the dot, if the straight lines in the grid appear wavy or are missing, it could be a sign of AMD. The grid should not in any way substitute for the advice of a qualified health care professional: it is not intended to constitute medical advice.

However, you may use it for at-home monitoring.

September 3, Age-related macular degeneration AMD , a leading cause of blindness worldwide, is as prevalent as cancer in industrialized nations. CNV suppression by CCR3 blockade was due to direct inhibition of endothelial cell proliferation, and was uncoupled from inflammation because it occurred in mice lacking eosinophils or mast cells, and was independent of macrophage and neutrophil recruitment.

In vivo imaging with CCR3-targeting quantum dots located spontaneous CNV invisible to standard fluorescein angiography in mice before retinal invasion. CCR3 targeting might reduce vision loss due to AMD through early detection and therapeutic angioinhibition. Ambati, J.
