What condition involves the cornea thinning and bulging forward?

Keratoconus
Retinal Detachment
Nystagmus
Pinguecula

The correct answer is: Keratoconus

Keratoconus is the condition characterized by the progressive thinning of the cornea, which leads to an abnormal bulging or conical shape of the cornea. This change in the cornea can significantly affect vision, causing distortions and changes in visual clarity. As the condition advances, it can lead to scarring and increased irregular astigmatism, making it important for early detection and management. The other conditions listed do not involve the cornea in the same way. Retinal detachment pertains to the retina, which is located at the back of the eye and involves a separation that can lead to vision loss. Nystagmus is characterized by involuntary eye movements and is primarily related to motor control issues rather than structural changes in the cornea. Pinguecula refers to a growth on the conjunctiva, which is not related to corneal shape or thickness changes. These distinctions highlight why keratoconus is the correct answer for this particular question.
