Contact Lens
Contact Lens evaluates and fits patients of all ages and medical
conditions with the latest in cosmetic and therapeutic contact
lens technology. Vitreo-Retina
When a retinal detachment develops, a separation occurs between
the retina and the underlying inner wall of the eye. This is
similar to wallpaper peeling off a wall. The part that is
detached (peeled off) will not work properly. The picture that
the brain receives becomes patchy or may be lost completely. An
operation is necessary to replace the detached retina in it's
proper position.
People often describe seeing "something black" or "a curtain",
"cobweb" or "flashing lights". In older persons these do not
necessarily indicate a serious problem. But the sudden
appearance of floaters and flashes requires a full eye
examination to exclude the presence of retinal holes or tears.
Nearly all retinal detachments develop because of a hole or tear
in the retina. This usually occurs when the retina becomes
'thin' especially in shortsighted people or if the vitreous
separates from the retina. One of the most common causes for
this is diabetes.
Angiography for eyes
This is a magnified photography of the retina using an
injectable dye. It helps classify the condition, record changes
in the retinal blood vessels, decide on the mode of treatment
and evaluate the treatment.
Medical Retina –(Retinopathy)
Diabetes causes weakening of the blood vessels in the body. The
tiny, delicate retinal blood vessels are particularly
susceptible. This deterioration of retinal blood vessels,
accompanied by structural changes in the retina, is termed
diabetic retinopathy and will lead to loss of vision.
Diabetic retinopathy is gradual in onset and is related to the
duration of diabetes. High blood glucose levels, high blood
pressure and genetics influence the development and progression
of diabetic retinopathy.
There are two main stages of diabetic retinopathy:
Non-proliferative: When the blood vessels leak, macular edema
may occur, thereby reducing vision.
Proliferative: When new, weak blood vessels grow or proliferate,
bleeding into the vitreous may occur and cause severe visual
loss. |
