Early-onset posterior polar cataract is a rare form of cataract that affects children and young adults. It is characterized by the formation of a white, opaque area in the back of the lens of the eye. This type of cataract can cause vision problems, including blurred vision, double vision, and difficulty seeing in low light. Treatment typically involves surgery to remove the cataract and replace it with an artificial lens.

The most common symptom of early-onset posterior polar cataract is blurred vision. Other symptoms may include glare, halos around lights, double vision, and difficulty seeing at night. In some cases, the cataract may cause a decrease in color vision or contrast sensitivity.

The causes of Early-onset posterior polar cataract are not well understood. However, some potential causes include genetic mutations, exposure to radiation, and certain medications. Other possible causes include diabetes, trauma, and inflammation.

The treatment for Early-onset posterior polar cataract is typically surgical removal of the cataract. This is usually done with a procedure called phacoemulsification, which uses ultrasound to break up the cataract and then remove it. In some cases, a laser may be used to help break up the cataract. After the cataract is removed, an artificial intraocular lens (IOL) is usually implanted to replace the natural lens.

There is no cure for early-onset posterior polar cataract. However, the condition can be managed with medications such as topical steroids, topical nonsteroidal anti-inflammatory drugs, and topical cycloplegic agents. Surgery may also be recommended to remove the cataract and replace it with an artificial lens.
