summary

Macular area is an important area of the retina, located in the posterior pole of the eye, which is mainly related to fine vision and color vision. Once the macular lesions, often appear visual loss, eye shadow or visual deformation. The symptom of senile macular disease? Let's talk about it

Symptoms of maculopathy in the elderly

The main symptoms of maculopathy are central vision loss, central scotoma and visual distortion. There was no inflammatory change in vitreous. There are yellow gray exudative lesions and hemorrhage in the macula, round or oval, with unclear boundary

The size is about 1 / 4-3 / 2 of the diameter of optic disc (PD). Most of them are below 1pd. There were arc-shaped or ring-shaped bleeding at the edge of the lesion, and occasionally radial punctate bleeding. There was a pigmented band around the lesion. Most of the lesions were centered on the fovea and within the radius of 1pd. At the end of the course, the macular area formed yellow white scar.

Wet macular degeneration: wet macular degeneration, accounting for 10% of the total incidence rate, is due to abnormal blood vessels growth under the retina, rupture of new blood vessels, bleeding, and the development of scar tissue, resulting in a sudden decrease in vision, which will rapidly and severely affect the central vision of patients, and even lead to loss of central vision. The main symptoms of wet macular disease are: rapid weakening of central vision, visual deformation, curving words and sentences on paper, dark shadow or fuzzy area in the center of vision.

matters needing attention

Laser treatment: use the heat generated by the laser to destroy the abnormal neovascularization in the macular area. Laser photocoagulation is only for blocking the existing neovascularization, and it can not prevent the formation of new neovascularization. It is a symptomatic treatment. At the same time, a little excessive laser can make choroidal neovascularization hyperplasia, and damage the normal tissue nearby, and the visual function will be greatly affected, so we must be vigilant.
