Venulus Inferior Retinal Macula: Anatomy and Role in Vision
The inferior retinal venule (English: v. macularis inferior) is one of the main veins that collects blood from the retina. It is located in the lower part of the retina and is part of the venous system of the eye.
Anatomically, the inferior retinal macula venule is formed from several small veins that collect blood from the lower part of the retina. It flows along the inferior border of the retinal spot and eventually connects with other veins of the eye to form the main vein of the eye.
The role of the inferior retinal spot venule in vision is that it is involved in the transport of oxygen and nutrients to the retinal cells. In addition, the inferior retinal macular venule plays an important role in the diagnosis of various eye diseases such as diabetic retinopathy, glaucoma and hypertension.
Diabetic retinopathy is a disease that occurs in people with diabetes and causes damage to the retina of the eye. The inferior retinal macular venule may become swollen and dilated in diabetic retinopathy, which can lead to poor circulation and blurred vision.
Glaucoma is a disease characterized by increased intraocular pressure and damage to the optic nerve. The inferior retinal macula venule may change its diameter during glaucoma, which may indicate a circulatory disorder in the retina.
Arterial hypertension is a disease characterized by high blood pressure. The inferior retinal macula venule may change its diameter during arterial hypertension, which may indicate a circulatory disorder in the retina.
In conclusion, the inferior retinal macular venule plays an important role in transporting oxygen and nutrients to retinal cells and may be an important indicator of various eye diseases. Regular eye examinations by an ophthalmologist will help identify possible problems in a timely manner and maintain eye health for many years.
Venula (from Latin vena - vein, veinula - thin vein), a section of the choroid of the eye located at the posterior pole. The venule lacks a physiological myelinated axon, which causes the nonfunctionality of this part of the retina. When the Venule is damaged, degeneration of the cones occurs, resulting in a decrease in visual acuity.
The retina on the posterior surface has a layer of pigment epithelium and nerve cells located above it, the endings of which form a speck. Among the latter, there are many types of violations. The most significant of these is complete spot syndrome, in which all centers end in defects in the form of black or white spots under the retina. They are visible only on the back of the eye.
