Introduction

Introduction Macular disc degeneration is a common age-related macular degeneration characterized by central vision loss, anterior shadow, and visual distortion. Traditional Chinese medicine is called "sight-seeing fainting", "sight-seeing color", and "visioning and reversing". The discoid degeneration of the macula often occurs in the elderly over 50 years of age, and the eyes can be diagnosed in both eyes with a longer course. Because the lesion is in the macula, the central visual acuity is seriously affected, and the lesion is not easy to disappear, and the visual prognosis is poor.

Cause

Cause

The cause of the disease is not fully understood, but most patients are accompanied by arteriosclerosis, which is generally thought to be due to choroidal capillary sclerosis in the macular area, dysfunction of the glass membrane, causing local pigmentation of the pigment epithelium and neuroepithelial layer in the macular area of the retina. Macular degeneration.

Chinese medicine believes that this disease is mostly due to old age, liver and kidney deficiency, lack of blood, yellow spots are not honored, or the spleen loses health, lack of gas, Qingyang does not rise, and the loss of support.

1.45 years old or older, both eyes have a history of onset, vision loss is more urgent.

2. Fundus examination: early macular depigmentation, foveal unclear or disappeared, mostly fusion of drusen. In the mid-macular area, serous or hemorrhagic discoid detachment occurred, severe subretinal hematoma, intraretinal hemorrhage, and vitreous hemorrhage. Late scar formation.

3. Fluorescein fundus angiography: choroidal neovascularization in the macular area, fluorescein leakage. Fluemic cases are covered by fluorescence.

Diagnosis

Differential diagnosis

Differential diagnosis of macular disc degeneration: atrophic age-related macular degeneration: atrophic or dry or non-exudative. Both eyes often develop and develop simultaneously, which is very similar to the clinical course and performance of senile hereditary macular degeneration. This type is characterized by progressive pigment epithelial atrophy, severe central visual impairment, and a virtual absolute central dark spot. There is a densely fused glassy sputum under the microscope and a large light gray atrophy zone. The boundary of the atrophy zone became clear, and there were salt and pepper-like spots scattered inside, and metal-like reflections were also observed.

More than 1.5 years old, both eyes have a history of onset, vision loss is more urgent.
