AI Article Synopsis
- A study investigated the microscopic tissue changes in 500 full-eyelid-thickness surgical specimens from patients with senile ectropion (25 cases) and senile entropion (25 cases).
- The research found that ectropion exhibited more significant issues like ischemia, atrophy, and collagen fragmentation in the orbicularis and Riolan's muscle compared to entropion, which had more atrophy in the septal and tarsal regions.
- Chronic inflammation and scarring were consistent features in both conditions, with the findings having a statistically significant difference at the 1% level, suggesting these tissue changes help differentiate between the two eyelid disorders.
Article Abstract
A microscopic histopathological study was done on 500 full-eyelid-thickness surgical specimens: 25 with the diagnosis of senile ectropion and 25 with that of senile entropion. Five different staining techniques were used. There appears to be significantly more orbicularis and Riolan's muscle ischemia, atrophy, and collagen fragmentation with ectropion than with entropion. Entropion shows more septal and tarsal atrophy. In both conditions, the skin and conjunctiva show chronic inflammation and scarring as a constant feature. Statistical significance at the 1% level was present for all six characteristics studied. These histopathological changes, if not etiological, are at least concomitant features differentiating senile ectropion from entropion at the microscopic tissue level.

The role of inflammatory periocular, ocular surface and systemic diseases in involutional ectropion.

Article Synopsis
- This study explored the link between involutional ectropion (an eyelid condition) and chronic inflammatory diseases affecting the eyelid and ocular surface, along with other systemic diseases.
- Researchers conducted a case-control study using medical records from Clalit Health Services in Israel, comparing patients with involutional ectropion to control groups with cataracts and other eye conditions, while controlling for age, sex, and ethnicity.
- Findings showed significant associations between involutional ectropion and various inflammatory diseases (like blepharitis and chronic conjunctivitis) as well as systemic conditions such as hypertension and dyslipidaemia, indicating these factors may be independent risk contributors to the eyelid condition.
Clinical Effect of the Anterior Fascia of Tarsus Tightening Combined With Lower Eyelid Blepharoplasty for Senile Entropion.
Ann Plast Surg
July 2021
From the Department of Ophthalmology, Daping Hospital, Army Medical University, Chongqing, China.
Objective: A majority of patients with senile entropion have a lower eyelid pouch. This study aimed to explore a modified method to correct the entropion and enhance ophthalmic cosmetology.
Patients And Methods: Patients with senile entropion and lower eyelid pouches, who underwent anterior fascia of tarsus tightening combined with lower eyelid pouch plastic surgery from 2018 to 2019, were enrolled in the study.
Barber Say Syndrome (A New Case Report).

Department of Family Medicine, Shiraz University of Medical Sciences, Shiraz, Iran.
Barber Say syndrome (BSS) is a rare ectodermal dysplasia with neonatal onset characterized by congenital generalized hypertrichosis, atrophic skin, ectropion and macrostomia. A literature review showed less than 20 previously reported cases of Barber Say syndrome. This presentation reports a one day old female with syndrome face, low hairline, coarse face, macrostomia, thin upper lip, bilateral ectropion and hypertelorism, hypertrichosis, senile skin appearance, hypoplastic nipples and one area of mild skin atrophy.

Purpose: The evaluation of palpebral laxity can be performed by the distraction test (DT). Although widely used in ophthalmologic practice, there is no consensus about the results considered normal by the test. The objectives of this study are to obtain the value of DT in a group of individuals with healthy eyelids and to compare with the measurements in subjects with senile ectropion.

Introduction: The lateral tarsal strip procedure (LTS) was first reported by Anderson and Gordy in 1979 for the management of paralytic or senile eyelid laxity. Since its description, the LTS procedure has been subject to several modifications by various authors. In this study, we described the Looi suture technique, a small modification in the technique of suturing the LTS to the lateral orbital wall periosteum.
