Objective  To evaluate the efficacy of adjunctive treatments to decrease herpes simplex keratitis (HSK) recurrences in patients with simultaneous stromal HSK and dry eye disease.

Methods  This was a nonrandomized, single-center, retrospective, comparative analysis. Forty-two patients were diagnosed with unilateral HSK and dry eye disease. Of the 42 patients, 22 were treated with ipsilateral punctal occlusion by thermal cautery and 10 were treated with topical administration of cyclosporine, 0.05%, ophthalmic emulsion twice a day. Another group of 10 patients had previously undergone punctal occlusion and had cyclosporine ophthalmic emulsion twice a day added. All patients continued the use of oral acyclovir or valacyclovir hydrochloride and topical steroids. The frequency and duration of HSK recurrences were monitored for 1 year after initiation of treatment, and the rates were compared with those in the prior year.

Results  The thermal cautery and topical cyclosporine groups experienced HSK recurrences for mean durations of 7.1 and 5.8 mo/y before treatment, respectively, and these were reduced to 1.1 mo/y after treatment in both groups. Topical administration of cyclosporine further reduced the duration of HSK recurrences in patients with prior thermal cautery from an average of 1.3 mo/y before the addition of cyclosporine to 0.8 mo/y after the addition of cyclosporine.

Conclusion  Permanent punctal occlusion by thermal cautery and the use of topical cyclosporine independently reduced recurrences of stromal HSK.
