Optic Atrophy

Overview

Optic atrophy could be a condition that affects the optic nerve, that carries impulses from the eye to the brain.

(Atrophy suggests that to waste away or deteriorate.) Optic atrophy isn't a sickness, however rather an indication of a probably a lot of serious condition.

Optic atrophy results from injury to the nervus opticus from many various types of pathologies. The condition will cause issues with vision, as well as sightlessness.

What are the symptoms of optic atrophy?

The symptoms of optic atrophy relate to a modification in vision, specifically:

• Blurred vision.
• Difficulties with peripheral (side) vision.
• Difficulties with color vision.
• A reduction in sharpness of vision.

Photophobia,

Overview 

Photophobia, or lightweight sensitivity, is AN intolerance of sunshine. Sources like daylight, fluorescent lightweight and incandescent lightweight all will cause discomfort, at the side of a desire to squint or shut your eyes. 

Headaches also may accompany light sensitivity. Light-sensitive people generally area unit discomposed only by bright lightweight.
In extreme cases, however, any light can be irritating.

Symptoms

Light sensitivity can also be a symbol of underlying diseases that do not directly have an effect on the eyes, like virus-caused diseases or severe headaches or headache.

Retinal Detachment

Overview

Retinal detachment describes AN emergency situation within which a skinny layer of tissue (the retina) at the rear of the eye pulls off from its traditional position.

Retinal detachment separates the retinal cells from the layer of blood vessels that gives chemical element and nourishment.

The longer retinal detachment goes untreated, the bigger your risk of permanent vision loss within the affected eye.

Symptoms

• Retinal detachment itself is painless.
• But warning signs nearly always seem before it happens or has advanced, such as:
• The unexpected look of the many floaters — little specks that appear to drift through your field of vision
• Flashes of sunshine in one or each eyes (photopsia)
• Blurred vision
• Gradually reduced side (peripheral) vision
• A curtain-like shadow over your visual field

Stye

Stye

There are multiple secretory glands present in both the upper and lower eyelids. These produce oils that enter the tear film through tiny ducts that open at the margins of the lids.

These make the tears less subject to the evaporative effects of the environment. Bacteria can frequently enter one or more of the eyelid oil glands and, if the opening of the duct clogs, an infection of the gland, or stye, may occur.

The stye causes a variable degree of inflammation, pain, and redness of the eyelid, and sometimes redness of the surrounding eyelid and cheek tissue. The medical term for stye is hordeolum.

Symptoms

• A lump on the top or bottom eyelid,
• swelling of the eyelid Pain,
• Redness,
• Tenderness to touch,
• Crusting of the eyelid margins,
• Burning in the eye,
• dry of the eyelid,
• Scratchy sensation on the eyeball,
• Blurred vision, Mucous discharge in the eye,

Swelling

A swollen eyelid occurs when there is inflammation or excess fluid (edema) in the connective tissues surrounding the eye. Swollen eyes can be painful and non-painful, and affect both the upper and lower eyelids.

A swollen eyelid may be a symptom of allergies or a sign of a serious eye infection.

• Eye irritation, such as an itchy or scratchy sensation
• Sensitivity to light (photophobia)
• Excess tear production, resulting in watering eyes
• Obstructed vision (depending on the extent of the swelling)
• Redness of the eyelid
• Red eyes and inflammation of the conjunctiva
• Eye discharge, or "mattering"
• Eyelid dryness or flaking
• Pain, particularly when swollen eyelids are caused by infection

Dry Eyes Syndrome

Dry Eyes Syndrome

One of the functions of tears is to keep your eyes lubricated, and when they fail to provide adequate lubrication for the eyes, you are being affected by dry eye syndrome. From your body being unable to produce enough tears to production of low quality tears, there can be a host of reasons behind inadequate lubrication for your eyes.

You can experience stinging or burning sensation when you have dry eyes, which can be experienced under certain situations, such as in an air-conditioned room, while traveling on an airplane or looking at a computer screen for a long time without any breaks.

Signs and Symptoms of Dry Eyes Syndrome

• A burning, scratchy or stinging sensation in eyes
• Eye redness
• Sensitivity to light
• Mucus production in or around the eyes
• Blurred vision
• Eye fatigue
• Issues in wearing contact lenses

Strabismus (Crossed Eyes)

Strabismus (Crossed Eyes)

Strabismus (or “Crossed Eyes”) represents misaligned eyes pointing in different directions and this misalignment can either be intermittent or constant. Strabismus exists in four common forms, i.e. “esotropia” and “exotropia”, “hypotropia” and “hypertropia”.

Esotropia is when one eye fixates on an object/point of interest, while the other eye turns in; whereas exotropia is when it turns out.

Similarly, turning down of the opposite eye whereas one fixes at some extent is hypotropia and hypertropia is once it turns up.

Strabismus usually occurs because the muscles controlling the movements of the eye and the eyelid, the extraocular muscles, fail to do so in a coordinative manner. Moreover, a disorder in the brain affecting the coordination of the extraocular muscles can also become the cause of strabismus. It can affect children as well as adults and about 4 percent of US population is believed to be suffering from this eye disease.

Signs and Symptoms of Strabismus

• Double vision

• Eyes’ inability to focus on a particular point at the same time

• Uncoordinated eye movements

• Loss of depth perception

Uveitis

Overview

Uveitis is a form of eye inflammation. It affects the center layer of tissue within the eye wall (uvea).

Uveitis  warning signs often come on suddenly and get worse quickly. They include eye redness, pain and blurred vision. The condition can affect one or both eyes.

It primarily affects people ages twenty to fifty, however it's going to also have an effect on kids.    Possible causes of redness ar infection, injury, or AN response or disease.

Many times a cause can't be identified. Uveitis will be serious, leading to permanent vision loss. Early designation and treatment ar necessary to stop the complications of uveitis.

Symptoms

•    Eye with uvea
•    The signs, symptoms and characteristics of uveitis include:
•    Eye redness,
•    Eye pain,
•    Light sensitivity,
•    Blurred vision,
•    Dark, floating spots in your field of vision (floaters),
•    Decreased vision ,
