Sir, Herpes Zoster is caused by the viral reactivation of Varicella Zoster virus, that enters the cutaneous nerve endings during an earlier episode of chicken pox and travels to the Dorsal Root Ganglia and remains latent. It is characterized by the occurrence of vesicular lesions grouped along the Single Dermatome innervated by Dorsal Root of Sensory Ganglion. Herpes Zoster Ophthalmicus (HZO) is involvement of the ophthalmic division of the fifth cranial nerve. It is the second most common type of Herpes Zoster (HZ), after Thoracic Zoster [1]. We present here, a case of Herpes Zoster in a young girl involving Supraorbital, Maxillary and Mandibular of the Trigeminal nerve. Timely diagnosis of HZO was made. The lesion on the tip of the nose (Hutchinson’s sign) alerted the involvement of Nasociliary nerve and to arrange immediate Ophthalmology consultation. Tele-Dermatology helped in reducing waiting time, fast delivery of care and prevention of visual disability [2]. The patient was monitored, motivated and treated, that could happen because of tele- dermatology. Dramatic improvement in the patient was observed in a very short time. The use of tele-dermatology, especially in times of the COVID – 19 pandemic is invaluable. The patient was a girl aged 12-years, presented through telemedicine with 3 days of lesions on the face mimicking acne. On close examination, there were a few Vesicular Lesions among multiple lesions and there was involvement of tip of the nose. Patient also complained of eye pain. This helped us to consider HZO. Prompt immediate treatment with anti-virus was initiated. It was possible to do continuous monitoring with the help of Tele-Medicine and without the patient having to leave the house in COVID era. Patient was advised to consult an Ophthalmologist for further evaluation. As it was essential, for examination of the eye parameters, patient had to attend in person. This one visit was not through Tele-Medicine. Patient was informed on day-1 of treatment that the condition may initially worsen under proper adequate treatment with a graphic representation (Fig. 1) and then decrease later. And this happened in our case, as seen in the six consecutive photographs as indicated below with date and time of the photographs by the patient, which are presented to illustrate the natural progression of disease under proper adequate treatment. This helped in avoiding panic to the patient. The lesions as seen in the pictures became aggressive in two days which means, the eye could have been affected more but for the immediate treatment given. Patient could get treatment from home by consulting online through out, thereby reducing the risk of venturing to a clinic in COVID situation. Except for one visit to the Ophthalmologist which was inevitable. Ocular Manifestations – Ocular manifestations affect about 50% of patients with HZO and can be isolated. This proportion reaches 80% in case of appearance of the Hutchinson Sign. The latter reflects the involvement of the nasociliary branch and is characterized by eruption on the side and on the tip of the nose [3]. Eye examination showed that there was congestion generalized in Conjunctiva. Corneal sensation was reduced, Iris anterior chamber, Pupil, lens, Fundus and extra ocular movements were normal. Immediate treatment was instituted after counselling about the treatment. The patient was advised Valacyclovir 1000 mg, 3 times a day for 7 days along with adequate fluid intake. For relief of pain, patient was given Pregabalin, Tremedol 25 mg and Gabapentin 6%W/W+Lidocaine 5%W/W smooth locally. Eye treatment As per Ophthalmologists advice, Polyethylene glycol 400 0.4% + Propylene glycol 0.3% five times a day and Acyclovir eye ointment a day was prescribed to the patient. All the pictures were taken by the patient and shared with the doctor, during the course of the treatment helping in regular monitoring have been presented (1a – 1f). In this case, Telemedicine gave the scope of reducing waiting time, providing correct diagnosis, enabling faster delivery of care, enabling tele based access to monitor the patient’s condition, counselling, management, monitoring with good end result. Key Takeaways • The importance of (Hutchinson’s sign) involvement of the tip of nose is emphasized. • Counselling the patient with regard to the possibility of worsening of the visible symptoms while under appropriate and adequate treatment, should be given with the help of a graphic representation (Fig. 2). • Prompt referral to Ophthalmologist is necessary. • The consultant and the patient should be conscious of associated potential Vision threatening complications and the need for prompt treatment to protect from visual complications.
