Ocular complications occur in about 50% of cases of ophthalmic zoster. They include inflammatory reactions of the eyelid, conjunctivitis, scleritis, keratitis, iridocyclitis, secondary glaucoma, optic neuritis, internal ophthalmoplegia, ocular motor palsies and exophthalmos. Very dangerous complications are a concomitant facial paralysis and a neuroparalytic keratitis. Then a tarsorrhaphy should be done in time. An ophthalmologist should be consulted, when the side of the tip of the nose presents vesicles (Hutchinson's rule).

Epstein-Barr virus (EBV) is a ubiquitous DNA virus of the herpesvirus genus with a high prevalence rate for antibody (about 90%) in the adult population. It is the most common causative agent of infectious mononucleosis syndrome. During recent years an increasing number of ocular disease entities have been reported to be linked to EBV infection. These entities include oculoglandular syndrome, conjunctivitis, dry eye, keratitis, uveitis, choroiditis, retinitis, papillitis and ophthalmoplegia. While EBV-specific serologic tests can now document recent and past primary infection with EBV and also identify patients manifesting atypical immunologic reactions to EBV, the lack of an animal model, the absence of clear-cut response to therapy and the paucity of documentation by culture render the pathogenesis uncertain or the association questionable in many of these cases.

Patients with chronic progressive external ophthalmoplegia (CPEO) are often disabled by ptosis; however, conventional ptosis surgery may induce lagophthalmos and exposure keratitis. Ten patients with CPEO underwent ptosis correction via bilateral frontalis suspensions, using monofilament synthetic material. Three of these patients were also treated with lower eyelid horizontal tightening. The frontalis sling was adjusted to provide a firm linkage between the eyebrow and eyelid, but was loose enough to allow eyelid closure when the frontalis muscle is relaxed. All patients experienced lessening of ptosis and relief from visual obstruction. One patient required reoperation of one eyelid for undercorrection. No lagophthalmos or corneal complications occurred. The rationale for treatment, preoperative evaluation, and operative procedure in CPEO is discussed herein.

A total of 136 injections was given to 83 patients for strabismus (99 injections), blepharospasm (29 injections), and spastic entropion (eight injections). All four patients with entropion experienced temporary benefits and early recurrence; one injection resulted in temporary paralytic ectropion. Two of 13 patients treated for blepharospasm developed transient bilateral blepharoptosis. Temporary and related sequelae of extraocular muscle injection included one periocular hemorrhage, one total ophthalmoplegia, and a 44% incidence (29 of 66 patients) of blepharoptosis, which in two patients lasted more than six months. Within three days of injection one patient developed homolateral acute herpes simplex keratitis and a second died of an acute myocardial infarction. No causal relationship for these events has been established.

Total ophthalmoplegia associated with biopsy-proven amyloid infiltration of the extraocular muscles developed in a 60-year-old man with multiple myeloma. Amyloid was also found in biopsy specimens of the conjunctiva and eyelid papules. The patient also had eyelid purpura, keratitis sicca, and pupillary abnormalities. Treating the multiple myeloma had no effect on the ophthalmoplegia. Physicians should be aware that ophthalmoplegia associated with amyloidosis may indicate an underlying myeloma rather than primary systemic amyloidosis.

66-year-old female patient presents palpebral bilateral ptosis and external ophthalmoplegia with a progressive evolution. The clinical aspects are completed with the affectation of the sensitive and motor trigemen, with the masseter atrophy and bilateral trophic keratitis. The affectation of the facial and acoustic nerves was associated with bilateral perception surditate. The hereditary transmission was dominant, with incomplete penetration. The neurogenic pathogeny was sustained on the basis of the association of neurological multilesions with III, IV, V, VI, VII, VIII nerves, with progressive extension.

It has been hypothesized that the distinct anatomic localization of the Graves' triad may be partially explained by pressure and trauma. While there are reports of local trauma clearly contributing to the pathogenesis of pretibial myxedema, direct evidence for a similar mechanism in Graves' ophthalmopathy (GO) has been lacking. We describe a 65-year-old male patient with stable mild Graves' ophthalmopathy of 24 years' duration in whom a retrobulbar block was administered prior to cataract removal. Three weeks after the procedure, he complained of rapidly progressive bilateral diplopia. In 6 months, there was moderate exophthalmos, exposure keratitis, almost complete ophthalmoplegia, and decreasing visual acuity requiring surgical decompression. Postdecompression, inflammatory signs and vision improved but there was complete ophthalmoplegia. The eye signs remained unchanged for the next 4 months but there was exacerbation of the disease within a week of receiving radioiodine despite concomitant steroid administration. Orbital irradiation was finally administered with rapid improvement in extraocular eye muscle function. We hypothesize that local inflammatory and immune responses stimulated by trauma and/or pressure in the retrobulbar compartment, triggered the development of severe ophthalmopathy in this patient. Thyroid-stimulating immunoglobulin (TSI) levels remained markedly elevated despite the clinical improvement suggesting that the beneficial effects of radiotherapy in this case were not mediated by suppressing TSI production.

Based on a review of 20 well-documented cases reported in the English literature between 1968 and 2008, herpes zoster ophthalmicus (HZO) may rarely be associated with complete unilateral ophthalmoplegia, defined here as impaired ocular ductions in all 4 directions within 3 months of onset of manifestations of HZO. Ophthalmoplegia occurred equally in immune-competent and immune-incompetent individuals. HZO preceded ophthalmoplegia in 75% by a mean interval of 9.5 days and a range of 2 to 60 days, occurred simultaneously with ophthalmoplegia in 20%, and followed by 2 days the onset of ophthalmoplegia in only 5%. Concurrent conjunctival inflammation, keratitis, or anterior uveitis was present in 90%. Lumbar puncture showed features of aseptic meningitis in 88%, slightly more than the 40%-50% found in patients with HZO without ophthalmoplegia. On orbit/brain imaging, abnormal enlargement of the extraocular muscles was present in 33%, and orbital soft tissue swelling was present in 17%. Enhancement of ocular motor cranial nerves was not reported. Complete or near-complete resolution of ophthalmoplegia occurred in 65% within a range of 2 weeks to 1.5 years (mean 4.4 months). A single autopsy report described granulomatous angiitis of the meninges and large vessels in the anterior cerebral circulation, as well as periaxial infarction in the optic nerve, pons, and medulla but without viral inclusion bodies or antigen. Unsettled issues are whether the pathogenesis is direct viral invasion or an immune reaction to the virus, whether the impaired ocular ductions are based on myopathic or neuropathic injury, whether there are predisposing factors to the combination of HZO and complete ophthalmoplegia, and whether treatment is effective.

The syndrome of inappropriate secretion of antidiuretic hormone (SIADH) associated with localized herpes zoster is rarely reported and may be under-appreciated. We describe two diabetic men with herpes zoster ophthalmicus (HZO) who developed hyponatremia (114 and 116 mmol/L) during acute illness. Both were euvolemic and had elevated urine osmolality (435 and 368 mmol/kg.H(2)O) and sodium (Na(+)) concentration (61 and 63 mmol/L) along with normal cardiac, renal, liver, and endocrine function consistent with the diagnosis of SIADH. Thorough investigation for other causes of SIADH, including detailed physical examination, laboratory studies, and computed tomography of the brain, chest, and abdomen, were negative. Despite antiviral therapy (acyclovir) for herpes zoster, ophthalmoplegia, keratitis, and post-herpetic neuralgia (PHN) developed. Even with fluid restriction and high salt diet, SIADH lasted for 3 to 4 months and resolved concomitantly with resolution of PHN, suggesting an association between SIADH and HZO. These two cases raise the potential for herpes zoster infection, especially HZO, to involve the regulatory pathway of ADH secretion, contributing to SIADH. The presence of PHN, which reflects greater neural damage may, at least in part, explain the prolonged ADH secretion and hyponatremia.

Although visual function is thought to be preserved in patients with locked-in syndrome (LIS), enabling them to communicate through vertical or lateral eye movements or blinking of the upper eyelid, nothing is known about the actual visual function of patients with LIS. The goal of this study is to evaluate the visual function of patients with LIS which may enable better evaluation of the state of consciousness of these patients. Patients with LIS seen in a single neurovascular unit of a tertiary center between 1997 and 2013 were retrospectively reviewed. Each patient had a specialized neuro-ophthalmological evaluation under optimal environmental conditions (light, contrast, examination distance, head position, best ergonomic adaptation, and establishment of a means of communication with help from the patient's friends/family). Visual acuity, extraocular eye movements, confrontational visual field, slit lamp and fundus examination were performed. Thirteen patients (6M/7F) were included in this study. Mean visual acuity was 20/60. Oculomotor examination was abnormal in 77%. Forty-six percent of patients presented binocular diplopia mainly related to a VIth nerve palsy. One patient presented complete ophthalmoplegia. Forty-six percent of patients had nystagmus responsible for oscillopsia (oculopalatal tremor). An abnormal visual field was observed in 17% of patients, and abnormal pupillary light response leading to photophobia was present in 22% of patients. Keratitis or dry eye syndrome was present in most patients and was a major cause of pain and visual impairment. Our results suggest that the visual function is impaired in all patients with LIS. This impairment is multifactorial including mostly binocular diplopia or oscillopsia but also refractive errors, dry eye syndrome, keratitis or visual field defect. This altered visual function may alter the ability of the patient to interact with his environment and lead to underestimation of their state of consciousness. An ophthalmologic evaluation would allow for improvement of these patients' comfort, their ability to communicate, and the assessment of their state of consciousness.
