Retinal Detachment Specialists in Dareeba, Delhi

What is Retinal Detachment?

Retinal detachment is a serious, sight-threatening emergency in which the retina, the light-sensitive layer at the back of the eye, pulls away from the underlying supportive tissue that supplies it with oxygen and nutrients. Once detached, the affected portion of the retina rapidly loses function, and without prompt treatment permanent vision loss can occur within days. It commonly follows a posterior vitreous detachment that creates a retinal tear, through which fluid seeps and lifts the retina away from its base. It can also result from trauma, advanced diabetic eye disease, or occur more readily in people with severe nearsightedness.

Causes of Retinal Detachment

Most cases occur when the vitreous gel inside the eye shrinks with age and pulls on the retina hard enough to create a tear, allowing fluid to accumulate underneath and separate it from the eye wall. Other causes include blunt or penetrating eye trauma, complications of advanced diabetic retinopathy pulling on the retina, and severe myopia, which stretches and thins the retina over time. Family history and previous cataract surgery also raise the risk of detachment.

Symptoms of Retinal Detachment

sudden appearance of many new floaters, flashes of light in the affected eye, a shadow or curtain-like darkness spreading across the field of vision, sudden blurring of vision, progressive loss of peripheral vision, distorted or wavy appearance of straight lines

Treatment & Types of Retinal Detachment in Dareeba, Delhi

Retinal detachment is treated as a surgical emergency; options include laser photocoagulation or cryotherapy to seal small tears before detachment progresses, and for an established detachment, pneumatic retinopexy, scleral buckle surgery, or vitrectomy to reattach the retina. The choice of procedure depends on the size, location, and underlying cause of the detachment. Outcomes are best when treatment is performed within hours to days of symptom onset, especially before the central retina, or macula, becomes involved.

Retinal detachment is classified into three types by mechanism: rhegmatogenous, the most common form, caused by a retinal tear that allows fluid to seep underneath and lift the retina away; tractional, where scar tissue, often from advanced diabetic retinopathy, physically pulls the retina away from the back of the eye; and exudative, where fluid accumulates beneath the retina without a tear, often due to inflammation, injury, or a tumor. The treatment approach differs considerably depending on which type is present.
