Background: Ocular complications of herpes zoster ophthalmicus (HZO) may lead to substantial visual disability, severe post-herpetic neuralgia and rarely fatal cerebral complications. Aim: To identify the pattern of ocular manifestation in herpes zoster ophthalmicus. Materials and methods: A cross-sectional descriptive study was under taken including the clinically diagnosed cases of HZO. All of them underwent a complete ophthalmological evaluation. Results: Sixty-eight cases of HZO were examined, of which 37 (54.4 %) were male and 31 (45.6%) female. The mean age was 48.7 ± 18.5 years. Most of the patients (64.7 %) were above the age of 40 years. 77.94 % of the patients had some form of ocular involvement. Pain (77.9 %) was the commonest ocular complaint. In young patients less than 35 years, HIV was the most common risk factor (19.3 %).Visual status was good in the majority (73.5 %) of patients at presentation. Lid and adnexal findings (45.8 %) were most common ocular involvement followed by conjunctivitis (41.1 %). Corneal complication was seen in 38.2 % of cases, uveitis in 19.1 % and post-herpetic neuralgia (PHN) and secondary glaucoma each in 5.8 %. Conclusion: Eyelid and ocular adnexal involvement is most commonly found in patients with herpes zoster ophthalmicus followed by corneal complication and uveitis. There needs to be awareness of ocular involvement, which can be sight threatening, among the HZO patients and other medical departments and an increased emphasis on regular ophthalmic examination.

Although it has been demonstrated conclusively that anti-viral medication reduces the duration and intensity of the manifestations of acute herpes zoster, controversy remains concerning its effectiveness in preventing post herpetic neuralgia and patients with this distressing condition are often referred to Pain Clinics. The problem is likely to become more prevalent in the future due to the ageing population, particularly in those over 80 years of age. Research, most of it uncontrolled so far, suggests that simple acupuncture starting in the acute phase, within 24–72 hours of the appearance of the skin eruption, could, if combined with anti-viral medication, produce a substantial reduction in the incidence and severity of post herpetic neuralgia. Further controlled clinical trials conducted at primary health care level are urgently needed.

Herpes zoster (HZ) is a painful, blistering skin eruption in a dermatomal distribution caused by reactivation of a latent varicella zoster virus in the dorsal root ganglia (DRG). Post-herpetic neuralgia (PHN) is the most common complication of acute herpes zoster (AHZ). Severe prodrome, greater acute pain and dermatomal injury, and the density of the eruption are the risk factors and predictors for developing PHN. PHN has a substantial effect on the quality of life; many patients develop severe physical, occupational, social, and psychosocial disabilities as a result of the unceasing pain. The long-term suffering and the limited efficacy of the currently available medications can lead to drug dependency, hopelessness, depression, and even suicide. Family and society are also affected regarding cost and lost productivity. The pathophysiology of PHN remains unclear. Viral reactivation in the dorsal root ganglion and its spread through the affected nerve result in severe ganglionitis and neuritis, which induce a profound sympathetic stimulation and vasoconstriction of the endoneural arterioles, which decreases the blood flow in the intraneural capillary bed resulting in nerve ischemia. Our rationale is based on previous studies which have postulated that the early interventions could reduce repetitive painful stimuli and prevent vasospasm of the endoneural arterioles during the acute phase of HZ. Hence, they might attenuate the central sensitization, prevent the ischemic nerve damage, and finally account for PHN prevention. The author introduces a new Ten-step Model for the prevention of PHN. The idea of this newly suggested approach is to increase the awareness of the health care team and the community about the nature of HZ and its complications, especially in the high-risk groups. Besides, it emphasizes the importance of the prompt antiviral therapy and the early sympathetic blockades for preventing PHN.
