“…In several previous studies, it was revealed that the chalazion resulted in changes in corneal astigmatism and aberrations due to the effect of mechanical compression (14)(15)(16). In addition, it has been reported that chalazion may cause an increase in intraocular pressure and that a decrease in intraocular pressure would be achieved after excision (17). It has been stated that lesions on the upper eyelid, involving the central eyelid and that are >5 mm, have a greater effect on corneal astigmatism and aberrations.…”

A chalazion is a lipogranulomatous inflammation that occurs due to blockage of the secretory ducts of the meibomian glands in the eyelids and may affect all ages of people (1). Causes of meibomian gland dysfunction, such as chronic blepharitis, rosacea, and seborrheic dermatitis, are risk factors for the development of chalazion (2). Ocular disorders such as cosmetic disturbances in the eyelids, visual disturbances, foreign body sensation, and ptosis may also occur (1).Corneal transparency is considered as an indicator of corneal health and may vary with many factors that cause corneal and endothelial dysfunction (3). Corneal transparency, which is evaluated subjectively by slit-lamp biomi- Objectives:The aim of this study was to investigate the effect of chalazion excision on corneal aberrations and corneal densitometry. Methods: Thirty-six patients with a chalazion in 1 eyelid and 40 healthy subjects were included in the study. Corneal aberration parameters of total root mean square (RMS), RMS high-order aberration (HOA), horizontal trefoil, oblique trefoil, horizontal coma, vertical coma, and spherical aberration values were measured using Scheimpflug corneal topography (Pentacam HR; Oculus Optikgeräte GmbH, Wetzler, Germany). Corneal densitometry values measured from 4 regions of the cornea (0-2, 2-6, 6-10, and 10-12 mm) and 4 corneal depths (anterior, central, posterior, and total) were recorded. Preoperative measurements of the patients (Group 1), postoperative first-month measurements (Group 2), and control group (Group 3) measurements were compared.

“…Some common eye diseases, such as congenital ptosis [ 11 ], eyelid hemangioma [ 12 ], allergic conjunctivitis [ 13 ] and bad eye rubbing habit [ 14 ], can cause astigmatism in children. It has been confirmed that large chalazions in the middle- upper eyelid could cause corneal astigmatism [ 15 – 18 ]. In an elderly man with farsightedness due to a chalazion mass in the middle-upper right eyelid, visual acuity returned to normal after the mass was removed [ 19 ].…”

“…Most studies on the relationship between chalazion and astigmatism have focused on corneal astigmatism rather than total astigmatism [ 15 , 17 , 18 ]. However, these studies have reported single-site masses, mainly larger masses in the middle-upper eyelid, and lack comprehensive studies of all site [ 15 , 16 ].…”

“…However, these studies have reported single-site masses, mainly larger masses in the middle-upper eyelid, and lack comprehensive studies of all site [ 15 , 16 ]. Moreover, the aforementioned studies have included mainly older children (> 7 years old) [ 25 ] or adults [ 15 – 17 , 19 ] with no reports on preschool children (except for case reports), and the sample size is small [ 15 , 16 , 18 ]. However, children aged 1–6 years old are more likely to develop chalazion, especially those between 2 and 5 years old [ 3 ].…”

Background Chalazion may affect visual acuity. This study aimed to evaluate refractive status of chalazia and effect of different sites, sizes, and numbers of chalazion on astigmatism. Methods Three hundred ninety-eight patients aged 0.5–6 years were divided into the chalazion group (491 eyes) and the control group (305 eyes). Chalazia were classified according to the site, size, and number. Refractive status was analyzed through the comparison of incidence, type, mean value and vector analysis. Results The incidence, type, refractive mean and of astigmatism in the chalazion group were higher than those in the control group, and the difference was statistically significant (P < 0.05). For comparison of the incidence, the middle-upper eyelid (50%) was highest, followed by 41.77% in the medial-upper eyelid, both higher than that in the control group (P < 0.05). In medium (54.55%) and large groups (54.76%) were higher than that in the control group (27.21%) (P < 0.05). In multiple chalazia, the astigmatism incidence for chalazion with two masses was highest (56%), much higher than that in the control group (P < 0.05). However, this difference was not significant in chalazion with ≥3 masses (P > 0.05). For comparison of the refractive mean,the medial-upper eyelid, middle-upper eyelid and medial-lower eyelid were higher than the control group (P < 0.05) (P < 0.05). The 3-5 mm and >5 mm group were higher than those in the control group and <3 mm group(P < 0.05), and the>5 mm group was larger than the 3-5 mm group，suggesting that the risk of astigmatism was higher when the size of masses > 5 mm. Astigmatism vector analysis can intuitively show the differences between groups, the results are the same as refractive astigmatism. Conclusion Chalazia in children can easily lead to astigmatism, especially AR and OBL. Chalazia in the middle-upper eyelid, size ≥3 mm, and multiple chalazia (especially two masses) are risk factors of astigmatism. Invasive treatment should be performed promptly if conservative treatment cannot avoid further harm to the visual acuity due to astigmatism.

“…Severe cases can cause eyelid eversion, eye deformities, and if secondary infections occur, they can develop into a stye [4][5][6] . Chalazion has a high incidence in children, and its treatment usually includes surgical and non-surgical methods [7][8] . The operation often needs to be performed under general anesthesia, which will cause many problems for children and parents.…”

BackgroundChalazion is a chronic inflammatory granuloma of the meibomian gland formed on the basis of the obstruction of the meibomian gland drainage duct and the retention of secretions. It is one of the most common clinically eye diseases in children. Chronic inflammation of the meibomian glands is responsible for this disease, and the gut flora is thought to be involved in the inflammatory process. In this study, we investigated the relationship between intestinal microbial composition and children's chalazion.MethodsFecal samples were collected from 21 children with chalazion and 26 healthy children. DNA was extracted from fecal stool samples and 16S rRNA sequences in the gut flora were detected by using second second-generation sequencing technology. The results were used to compare the composition of the microbiome between patients and healthy controls.ResultsAccording to Alpha Diversity and Beta Diversity analysis, we found that there was no significant difference in bacteria diversity and relative abundance between the two groups. We compared the flora of the control group and the diseased group through Lefse analysis, and screened out 11 different species. Based on the absolute abundance of species, 43 different species were selected. Anosim analysis and metastats analysis were used to compare the flora of the control group and the diseased group again. At the species level, we found that gut_metagenome and human_gut_metagenome are the common differences in species levels obtained from the above analysis. Finally, corrplot correlation analysis was performed, suggesting that gut_metagenome has a great correlation with the number, ulceration, and recurrence of chalazion in children.ConclusionsThere was no significant difference in the diversity index and relative abundance of flora in children with chalazion compared with healthy children, but there were significant differences in some bacterial species. The gut_metagenome strains identified in this study were significantly related to the growth, ulceration, and relapse of children with chalazion. It is suggested that gut_metagenome may be a microbiological indicator which is independent of clinicopathologic factors but associated with chalazion disease .* These authors have contributed equally to this work.
