Ropy Posterior Polymorphous Corneal Dystrophy: Understanding Symptoms, Diagnosis & Treatment

Posterior Polymorphous
Posterior Polymorphous Corneal Dystrophy (PPCD), also known as ‘Ropy’, is an inflammatory and degenerative condition of the eye’s cornea. It is caused by the accumulation of abnormal glycoproteins in the deep layers of the cornea and is characterized by a progressive thinning and deterioration of the corneal tissue. PPCD is usually diagnosed in individuals between 20 and 50 years of age, however it may affect both older and children.

Symptoms of Posterior Polymorphous Corneal Dystrophy

The primary symptom of PPCD is the presence of thin and filmy white lines in the eye, termed ‘ropes’. This rope-like pattern may be seen around both the peripheral and central areas of the cornea. Other symptoms may include light sensitivity, blurry or distorted vision, eye pain, irregular astigmatism and redness of the eye.

Diagnosis of Posterior Polymorphous Corneal Dystrophy

PPCD is usually diagnosed through a comprehensive eye examination. During the examination, the doctor will perform a slit lamp exam, evaluate refractory errors, and measure intraocular pressure. Images of the cornea may also be taken to diagnose and monitor the progression of the disorder.

Treatment and Health Prognosis

In most cases, PPCD can be treated with glasses, contact lenses, and ocular lubricants. Surgery may be recommended in more advanced cases to provide relief from the symptoms. Although PPCD is incurable, the prognosis for long-term vision is generally good if it is detected early and managed properly.
