Ophthalmia :

In some cases due to a lineal eye injury, Sympathetic Ophthalmia can develop. This can present itself as a Uveitis, it will happen when the resistant power of our body attacks the damaged eye first and then affects the healthy one.

This Sympathetic Ophthalmia (SO) will happen very rarely, it can occur in 0.2 to 0.5% of non-surgical eyes wounds and less than 0.01% of surgical eye wounds.

In this condition we didn’t feel any pain, however, the eyes will experience blurred vision and the eyes lose their capability of focus. 80 percent of cases this SO will occur within three months of injury and 90 percent of cases it will occur within one year of the period.

When we went for a slit-lamp checkup, the doctor may observe the cluster of provocative cells on the posterior corneal surface. If the sight increased in the injured eye, the removal of the complete injured eyeball will take place. If the sight of the injured continues, or either if the medical action is unable to prevent autoimmune response, then the usage of the drug called corticosteroid may be used to control the intervention and immunosuppressive will take place. In this, it may also use T-cell drugs such as Cyclosporine, which is partially concealed immune system activity.

Dry Eyes:

The main reason for dry eyes is lack of oily or slippery substance (known as Lubricant) and moisture on the surface of the eye. The effect of dry eyes ranges from delicate, however it makes constant eye irritation and critical inflammation.

Healthy eyes can have a sufficient and consistent layer of tears on the eye surface. Tears will help to clean the eye surface and keep it moist and non-dust. Microorganisms can make damage to the cornea (front surface of eyes) and lead to an eye infection.

The tear films consist of some different layers,

  • Lipid component (Oily)
  • Aqueous Component (Watery)
  • Mucin Component

Each component has different purposes, such as the lipids will help to make smooth eye eyes by stopping the evaporation of tears, and mucin will help to spread the tears to the complete surface of the eyes. These individual tear components can be produced by different organs on the eye.

In some cases the other reason for dry eyes is the failure to produce enough aqueous (watery fluid), to keep eyes moisture which is known as “aqueous deficiency dry eyes”.
