Which is true regarding the treatment of a deep stromal ulcer?

In the management of deep stromal ulcers, it is important to recognize that significant stromal loss can compromise the structural integrity of the cornea and its ability to heal properly. When there is a loss of 50% or greater of the stromal tissue, the likelihood of spontaneous healing diminishes considerably. In such cases, surgical intervention, often in the form of techniques like conjunctival grafts or penetrating keratoplasty, becomes necessary to restore corneal architecture and promote healing.

The other responses do not accurately reflect the complexities involved in treating these ulcers. For instance, while surgical intervention may not always be required for superficial ulcers, deep stromal ulcers with substantial stromal loss definitely warrant surgical action to prevent complications like corneal perforation or persistent corneal edema. Additionally, the use of topical steroids is not advisable in deep stromal ulcers since they can suppress the healing process and increase the risk of infection. Lastly, healing is typically not quick without intervention for deep stromal ulcers, as they often lead to more serious ocular issues that require timely and appropriate treatment to recover effectively.
