Corneal Ulcer (Keratitis)Treatment

Corneal Ulcer (Keratitis)Treatment:

Depending on the laboratory reports, treatment will be started. Antibiotics, antifungals or antivirals are started in the form of tablets and eye drops depending on the causative agent. In cases of large or severe corneal ulcer (keratitis), fortified eye drops are started which are prepared from available injectable preparations. This is accompanied by oral pain killers, cycloplegics eye drops which relieves pain, anti glaucoma eye drops to reduce the intraocular pressure and artificial tears. The frequency depends on the size of the ulcer. Corticosteroids are strictly prohibited in cases of fungal corneal ulcer (keratitis). However, they can be considered in other types of ulcers at a later stage under extreme caution and supervision.

In case of a small perforation, tissue adhesive glue is applied over the perforation under sterile conditions followed by a bandage contact lens to seal the perforation. Bandage contact lenses are also used in cases of recurrent epithelial erosions for better healing. Patients who have eyelid deformities, leading to an ulcer, need corrective surgeries. If the corneal ulcer (keratitis) is due to an eyelash growing inward, the offending lash should be removed together with its root. If it grows back in an abnormal manner, the root may have to be destroyed using a low-voltage electrical current. In cases of improper or an incomplete lid closure, a surgical fusion of the upper lid and lower lid is done. Small perforations are also treated with patch grafts which means taking a full thickness or partial thickness graft from the donor cornea and anchoring it over the perforated site.

For non healing ulcers surgical intervention is required. An amniotic membrane graft is placed on the cornea under sterile conditions to build thickness and establish healing. However, in cases of larger perforation or severe scarring, corneal transplant surgery is done which involves surgical removal of the diseased corneal tissue and replacing it with a healthy donor tissue.
