2. Purpose/Objective • To report the restoration of visual acuity in an 11 year old boy after medical treatment of a severe alkaline burn of both eyes.

3. Background • Ocular alkaline burns to the eyes denature proteins in the cornea, conjunctiva, and other ocular structures. The release of collagenases and proteases after injury leads to corneoscleral melting. • The role of topical steroids in corneoscleral melting is controversial as they have been postulated to exacerbate this condition. • Adjunctive therapy with mucomyst, doxycycline, and amniotic membrane help prevent corneal melting. • Amniotic membrane is effective at promoting re-epithelization, reducing inflammation, and scaring. • Mucomyst inhibits collagenase whereas tetracyclines exert anti-collagenolytic effects by inhibiting activities of human interstitial collagenases and by preventing the oxidative activation of latent pro-collagenases.

4. Methods • Study Design: Observational case study “The study protocol was approved by the Human use Committee at Tripler Army Medical center. Investigators adhered to the policies for protection of human subjects as prescribed in 45CFR 46”

5. Results • An 11 year old boy sustained ocular alkaline burns bilaterally. After copious irrigation for two days, the ocular pH normalized from ph 9.0. • Then he was treated with aggressive medical therapy, which included maxitrol, mucomyst, doxycycline, erythromycin, and cyclopentolate. • Later, diamox was added to treat elevated intra-ocular pressure. • He developed symblepharons and large epithelial defects bilaterally (OD > OS). Therefore Prokera was applied to the right eye and a bandage contact lens to the left. Then Vigamox and pred-forte were started for 1 week. He was maintained on mucomyst, diamox, doxycycline and lotemax for six months. • Symblepharon excission was performed . • His visual acuity improved to 20/20 bilaterally. Minimal corneal neovascularization occurred in the right eye.

8. Conclusions • Prompt and aggressive medical treatment can restore visual acuity in severe ocular alkali burns. • Mucomyst and amniotic membrane may be an important adjunctive therapy in restoring vision.
