Retinopathy of Prematurity refers to a disease of the eye, seen in premature babies. The condition causes blood vessels in the eye to grow abnormally and eventually bleed or leak, leading to scarring of the retina. As the scar starts to shrink, it pulls on the retina, detaching it from the back of the eye. Since the retina is an essential part of the visual apparatus, its detachment can potentially lead to blindness.

ROP may also lead to other complications such as

People may suffer from visual impairment even though their eyes are perfectly normal. Such loss of vision may result from neurological impairment.

Vision is the combination of image formation and perception of various attributes of the image by the brain. When the brain is not able to perceive images or various attributes of images, the patient may suffer from neurological impairment of vision. Such impairment owes its origin to the nervous system.

It is an eye disorder in which the retina is affected by abnormal growth of the blood vessels. Most of the time only one eye is affected. This is not an inherited disease and the principle causes are still unknown. Although in some cases, it has been speculated that some acquired somatic alterations in the NDP gene (Norrie disease (pseudoglioma)) causes Coats disease. The treatment depends upon the symptoms and the intensity of the disease.

There are many symptoms which can be seen in...more

Lattice degeneration is a disease of the human eye wherein the peripheral retina becomes atrophic in a lattice pattern and may develop tears, breaks, or holes, which may further progress to retinal detachment. It is an important cause of retinal detachment in young myopic individuals.
Treatment of lattice is typically prophylactic. In rare cases, the doctor performs a “barrier” laser to “tack down” the retina surrounding these lesions to avoid the possibility of retinal detachment. If the do...more

Any patient who needs to undergo cataract surgery must be evaluated in a thorough manner so as to establish the requirement, appropriateness, expected surgical problems, expected benefits and co-morbid conditions having an influence on cataract surgery.

The preoperative assessment consists of-

Anxiety is the most common type of emotion. Every now and then, especially in times of difficulties, we all can feel anxious. There are many different forms of it.
Anxiety may occur as a symptom of clinical depression. It's also common to have depression that's triggered by an anxiety disorder, such as generalized anxiety disorder, panic disorder or separation anxiety disorder. Many people have a diagnosis of both an anxiety disorder and clinical depression.
You may need an immediate con...more

Macular Degeneration is an age-related macular degeneration incurable eye disease, which might result in blurred vision or no vision in the centre of the vision field, which might lead to visual distortions, reduced central vision, decreased intensity of the colours and can make it difficult for the patient to recognize faces, read, drive and to perform other activities.

Types of Macular Degeneration
1. Dry Macular Degeneration: It is characterized by the presence of drusen and thin...more

Macular Degeneration is a condition in which the central part of the retina degenerates. In this condition, the posterior part of the eye, retina, is affected.

The central part of retina, macula, is associated with the central vision in the eye. The macula is responsible for controlling various abilities, such as distance perception, perceiving faces and colours, and identifying fine details of the objects. When this central part degenerates, the person slowly loses the ability to see c...more

Even something as small as an eyeball has multiple parts within it. The retina at the back of the eyeball is responsible for the clarity of vision. The central area of the retina is known as the macula. Macular degeneration is the deterioration of this part of the retina. Macular degeneration is age-related and considered an incurable condition. People suffering from macular degeneration experience blurred vision, black spots and may eventually lose central vision while retaining peripheral visi...more
