Contact blepharoconjunctivitis due to black henna — A case report

Development and validation of a health practitioner survey on ocular allergy

Survey studies have played a significant role in understanding the gaps in the knowledge and practices of health practitioners. However, there have been no such survey studies on Ocular Allergy (OA). Thus, the purpose of this study was to develop and validate a survey on OA to better understand the gaps in the diagnostic, treatment, and collaborative care approaches of health practitioners in OA. The survey is titled "Survey on Ocular Allergy for Health Practitioners (SOAHP)". SOAHP was developed in a five-stage process. First, item extraction via the use of a literature review, second, face and content validity, third, a pilot study, fourth, test-retest reliability, and fifth, finalisation of the survey. 65 items under 6 domains were initially generated in the item extraction phase. Content validity was conducted on 15 experts in the field. This was conducted twice to reach consensus whereby items and domains were added, edited, kept, or removed, resulting in 50 items under 7 domains. The pilot study was conducted on 15 participants from the five relevant health practitioner fields (Allergists/Immunologists, General Practitioners (GPs), Ophthalmologists, Optometrists and Pharmacists). This altered the survey further to 40 items under 7 domains. Test-retest reliability was conducted on 25 participants from the five health practitioner fields. Reliability was moderate to almost perfect for most (97%) investigated items. The finalised survey was 40 items under 7 domains. SOAHP is the first survey created to assess diagnostic, treatment and collaborative care approaches of Allergists/Immunologists, GPs, Ophthalmologists, Optometrists and Pharmacists on OA. SOAHP will be a useful tool in clinical research on OA.

Black Henna Deposits Masquerading a Melanoma of the Plica Semilunaris

PURPOSE

The aim of this study was to describe a rare case of conjunctival black henna accumulation that was clinically misdiagnosed as melanoma.

METHODS

This retrospective case report reviewed the clinical findings and histopathologic features of a pigmented plica semilunaris lesion excised from a 63-year-old woman. The patient had a history of regular use of black henna in her childhood. The conjunctival pigmentation was present since her early teenage years but started to grow only recently.

RESULTS

There was a darkly pigmented mass mainly covering the plica semilunaris of the right eye with additional irregularly scattered pigmentation in the medial bulbar conjunctiva. Excisional biopsy of the plical tumor revealed nodular pigment deposits with lymphocytic infiltration. There were no neoplastic cells. The specimen stained negative for pan-keratin, CD68, and CD34. Melanin bleaching was also negative.

CONCLUSIONS

Long-term exposure to black henna as a hair dye may lead to subconjunctival accumulation and mimic melanoma.

Ocular Side Effects of Eyelash Extension Use Among Female Students of the University of Benin, Benin City, Edo State, Nigeria

Introduction Eyelash extensions have become a trendy cosmetic procedure, especially among young female students at various universities. This study assessed the relationship between the usage pattern of eyelash extensions and the ocular side effects arising from eyelash extension use. Methods The study was conducted using 400 female undergraduate students at the University of Benin with an age range of 15-30 years and a mean age of 22.50 ± 3.79 years. This observational cross-sectional study was conducted by evaluating the usage pattern of eyelash extensions, ocular side effects, and the relationship between them. Data obtained from the participants were processed using the Pearson correlation analysis in the Statistical Product and Service Solutions (SPSS) (version 22.0; IBM SPSS Statistics for Windows, Armonk, NY) software. Results The results showed that only 16% (n=64) of the participants had any side effects before fixing eyelash extensions, while 54% (n=216) of the participants had experienced one or more side effects during/after artificial eyelash wear. The most common side effects experienced were itching (n=152, 38%), lashes pulling out (n=144, 36%), heavy eyelids (n=136, 34%), and red eyes (n=136, 34%). Other ocular side effects were grittiness/foreign body sensation (n=128, 32%), tearing (n=96, 24%), burning sensation (n=96, 24%), pain on the eyelids (n=88, 22%), misdirected lashes (n=40,10%), eyelids swelling (n=24, 6%), a boil on eyelids (n=16, 4%), and discharge (n=8, 2%). Moreover, the result showed statistically significant correlation between the usage pattern and the ocular side effects such as pain (r=0.22), itching (r=0.23), tearing (r=0.21), burning sensation (r=0.17), a boil on the eyelids (r=0.21), heavy eyelids (r=0.16), misdirected lashes (r=0.22), red eyes (r=0.15), lashes pulling out (r=0.12), eyelids swelling (r=0.18), grittiness (r=0.10), and discharge (r=0.10) (p<0.05). Conclusions It is concluded that there is a relationship between the usage pattern of eyelash extensions and the ocular side effects. Adequate and proper attention should be paid to this ever-growing cosmetic procedure's potential visual health risks.

TFOS Lifestyle: Impact of cosmetics on the ocular surface

In this report the use of eye cosmetic products and procedures and how this represents a lifestyle challenge that may exacerbate or promote the development of ocular surface and adnexal disease is discussed. Multiple aspects of eye cosmetics are addressed, including their history and market value, psychological and social impacts, possible problems associated with cosmetic ingredients, products, and procedures, and regulations for eye cosmetic use. In addition, a systematic review that critically appraises randomized controlled trial evidence concerning the ocular effects of eyelash growth products is included. The findings of this systematic review highlight the evidence gaps and indicate future directions for research to focus on ocular surface outcomes associated with eyelash growth products.

An analysis of 275 DIY recipes for eye cosmetics and their possible safety issues

Some consumers have become very suspicious of certain health products such as medicines, medical devices and cosmetics. This can lead them to choose to make such products themselves. The aim of this work was therefore to analyse recipes for eye makeup and makeup removal products, as well as eyelash and eye contour care products. We collected recipes for do‐it‐yourself products found on blogs and social media (YouTube channels, Facebook, Pinterest, Instagram and TikTok) in French and English and then analyse their composition as well as how practical it is to make these recipes. We compiled and studied 275 recipes for products that can be used in or around the eye (periocular area). This work has shown that the quantities of the various ingredients are very imprecise, that the proposed substances are not suitable for the intended use and that the preservation of the finished products is not sufficiently guaranteed. The results obtained suggest that recipes for products intended for use in the eye or in the periocular area are not safe to use and that their use is likely to have relatively serious consequences.

Side-effects of henna and semi-permanent 'black henna' tattoos: a full review

Henna, the dried and powdered leaf of Lawsonia inermis, is widely used as a dye for the skin, hair, and nails, and as an expression of body art, especially in Islamic and Hindu cultures. As it stains the skin reddish-brown, it is also called red henna. Black henna is the combination of red henna with p-phenylenediamine (PPD), and is used for temporary 'black henna tattoos'. This article provides a full review of the side-effects of topical application of red and black henna, both cutaneous (allergic and non-allergic) and systemic. Red henna appears to be generally safe, with rare instances of contact allergy and type I hypersensitivity reactions. In children with glucose-6-phosphate dehydrogenase deficiency, topical application of henna may cause life-threatening haemolysis. Black henna tattoos will induce contact allergy to its ingredient PPD at an estimated frequency of 2.5%. Once sensitized, the patients may experience allergic contact dermatitis from the use of hair dyes containing PPD. There are often cross-reactions to other hair dyes, dyes used in textiles, local anaesthetics, and rubber chemicals. The sensitization of children to PPD may have important consequences for health and later career prospects. Systemic toxicity of black henna has been reported in certain African countries.
