Retinal Vessel Occlusion The retina is the light-sensitive layer at the back of the eye that is responsible for vision. Blood circulation to most of the retina's surface is primarily through one artery and one vein. If either blood vessel or one of their smaller branches is blocked, blood circulation to the retina can be significantly disrupted. The blockage is called an occlusion.

Nasal Congestion Conditions that cause chronic congestion of the nose may contribute to sleep apnea. Nasal congestion is also a common symptom that occurs in individuals with a deviated septum. This is a condition in which the bone and cartilage in the center of the nose is crooked or off center. This results in breathing difficulty.n such cases, the congestion is likely to subside within a week. Other causes of nasal congestion include allergic rhinitis, nasal polyps or vasomotor rhinitis. Pregnant women may also experience congestion of the nose due to hormonal changes taking place in the body.

Retinal vessel occlusion A retinal vessel occlusion is a blockage in the blood vessel of your eye that can result in sight loss. There are two types of retinal blood vessels, arteries and veins. Either of these can become blocked and each of them can affect the eye in different ways. The visual loss caused by retinal vein and artery occlusions is painless. It is usual for only one eye to be involved at a time, but occasionally both eyes may be affected at the same time.

- Nasal obstruction can occur due to anatomic abnormalities of normal structures in the nose, or inflammatory processes that lead to swelling in the nose. This page discusses anatomic causes of nasal obstruction. For inflammatory causes, please see the pages on Allergy and Sinusitis. The most common causes of anatomic obstruction in adults are related to the shape and size of the nasal septum and turbinates, and less commonly the size of the adenoids.
