The electromyographic analysis of orbicularis oculi muscle in epiphora.

Indian J Ophthalmol 2022 Jun;70(6):2094-2100

Department of Ophthalmology, Kartal, Dr. Lutfi Kirdar City Hospital, Istanbul/, Turkey.

Purpose: Functional epiphora is a clinical condition that presents with the complaint of watery eyes, but without anatomical stenosis in the lacrimal drainage system. Although the mechanism is not clear, there are various possibilities involving the movement of the orbicularis oculi muscle, especially its deeper segment (Horner's muscle). We aimed to evaluate the function of the orbicularis oculi muscle in patients with patent, but dysfunctional lacrimal drainage system using a quantitative motor unit potential (MUP) analysis.

Methods: Twenty-eight patients with functional epiphora (mean age = 59 years) and a control group of 28 volunteers were included in the study. Inclusion criteria were persistent and symptomatic epiphora or wiping >10 times per day and diagnosis confirmation by lacrimal irrigation test. Electromyography (EMG) was performed on the deeper segment of the orbicularis oculi muscle (medial and lateral parts). MUP parameters (duration time, amplitude, number of phases, number of turns, area, rise time, and thickness) were evaluated in both groups. Any increase in amplitude, prolongation time (>14 ms), number of turns, and satellite potential was taken as characteristic of the neurogenic type of epiphora, whereas shortened motor unit duration time, increased phase number, and low amplitude are the features of myopathic type.

Results: Upon MUP analysis of the medial and lateral orbicularis oculi muscle, the increase in duration and thickness values in the medial part and the increase in duration, amplitude, area, and thickness values of the lateral part were found to be statistically significant in the patient group compared to the control group (P < 0.001). In the evaluation of the patients' medial and lateral orbicularis oculi muscle, the increase in phase values and decrease in amplitude, area, and rise time values were found to be statistically significant (P = 0.024, P < 0.001, P < 0.001, and P = 0.010, respectively).

Conclusion: These data show that functional epiphora is due to neurogenic damage of the orbicularis oculi muscle and should be investigated in more detail.

Characteristics of pediatric and adult cases with open globe injury and factors affecting visual outcomes: A retrospective analysis of 294 cases from Turkey.

Ulus Travma Acil Cerrahi Derg 2018 Jan;24(1):31-38

Department of Ophthalmology, Ümraniye Training and Research Hospital, İstanbul-Turkey.

Background: This study aimed to evaluate 1-year follow-up results of cases that were diagnosed with open globe injury (OGI), to compare trauma-related characteristics between pediatric and adult cases, and to determine risk factors for a poor final visual acuity.

Methods: This study enrolled 294 cases that met the OGI definition and were followed up for at least 1 year. Demographic and clinical features regarding ocular trauma were recorded. The cases were divided into two groups according to age: pediatric (≤16 years) and adult (>16 years) groups.

Results: Children were exposed to accidents that led to OGI mostly at home, whereas adults were exposed to such accidents mostly in the office. Penetrating injuries were more common in children than in adults, and injuries most commonly occurred owing to spiky objects. Zone I injuries were most frequent in both children and adults. The frequency of high-grade injuries increased with age. Foreign body injuries and multiple surgeries were more common in adults than in children. There was no difference between the two age groups based on ocular trauma score (OTS) and visual acuity. OTS predicted the need for multiple surgeries. In the adult group, age, multiple surgeries, and initial visual acuity were significant risk factors for the final visual acuity that was achieved.

Conclusion: OGI causes and risk factors for poor final visual outcomes differ in adults and children. The knowledge of these differences is crucial for taking adequate preventive measures and decreasing morbidity.
