A Case of Herpes Zoster Ophthalmicus With Multiple Delayed Ocular Complications.

Herpes zoster ophthalmicus (HZO) presents a variety of ocular complications, most of which occur simultaneously as skin lesions. We report a case of HZO with delayed onset of multiple ocular complications. A 72-year-old man developed HZO, blepharitis, iritis, and conjunctivitis in the left eye, which resolved after topical ocular treatment and systemic acyclovir administration. However, six weeks after the first onset of the rash, the patient came to our hospital because of recurrent blepharitis, iritis, scleritis, conjunctivitis, eye pain, ptosis, and blurred vision in the left eye. Best corrected visual acuity (BCVA) in the left eye had decreased to hand motion, and the Goldmann visual field test showed only mild residual peripheral vision on the lateral side. Intraocular pressure showed 25 mmHg in the left eye and inflammation in the anterior chamber with paralytic mydriasis. Orbital magnetic resonance imaging (MRI) showed the contrast effects with the lacrimal gland, superior ophthalmic vein, supraorbital nerve, optic nerve, and around optic nerve sheath. The patient was diagnosed with optic neuritis, optic perineuritis, ptosis, paralytic mydriasis, trigeminal neuralgia, lacrimal gland inflammation, blepharitis, iritis, scleritis, and ocular hypertension after HZO, and three courses of steroid pulse therapy were administered. Thereafter, BCVA improved to 0.3 in the left eye, with improvement in central vision, and MRI lesions and other symptoms also improved. The patient has had no complications or recurrence of HZO. HZO can cause a variety of ocular complications. Since autoimmune mechanisms might be involved, combined immunotherapy should be considered.
