Post-Traumatic Corneal Hydrops In Patients Without Keratoconus

To describe two cases of corneal hydrops after ocular trauma without a history of keratoconus.

The cases of two patients referred from other centers to the Carlos Andrade Marín Hospital (Quito - Ecuador) are presented.

Case 1: 32-year-old patient with a history of right eye trauma at age 30 who presented superior temporocorneal hydrops with good response to treatment

Case 2: A 24-year-old patient with a history of left eye trauma at 9 years of age and presented corneal hydrops at 20 years of age in the superior temporal area.

Both cases underwent treatment with a compressive ocular patch with resolution of hydrops and are currently on the waiting list for deep anterior lamellar transplantation. In the topographic study of the contralateral eye, no signs of keratoconus were found.

The corneal hydrops in these patients presents an atypical location with respect to corneal hydrops secondary to keratoconus. It allows us to believe that trauma can cause a biomechanical deficit similar to that of keratoconus by rupturing Bowman's membrane and triggering the pathophysiology of corneal hydrops.

The biomechanical alterations that can trigger corneal hydrops may be due to old ocular trauma.
