Which of the following can NOT be a cause of retinal detachment?

Retinal detachment occurs when the retina separates from the underlying supportive tissue, which can lead to vision impairment or loss. The causes of retinal detachment are predominantly associated with conditions that affect the retina or vitreous body.

Vitreous disease can cause retinal detachment through mechanisms such as vitreous traction, where a gel-like substance (the vitreous) pulls on the retina, potentially leading to tears and separation. Congenital malformations can predispose an individual to retinal detachment by presenting structural abnormalities that affect how the retina is anchored to the eye. Ocular inflammation may lead to conditions such as uveitis, which can result in changes to the vitreous or retina, contributing to detachment.

On the other hand, a corneal abrasion is an injury to the outer layer of the eye, the cornea, and does not directly relate to the retina or its ability to remain attached. While it can cause significant pain and may result in complications, it does not contribute to retinal detachment. Hence, identifying this distinction clarifies why corneal abrasion is not a cause of retinal detachment.
