Abstract
Introduction
Visual loss and impairment due to eye trauma are not only found to affect the visual acuity of patients, but also their quality of life, causing occupational and social dysfunctions (1). It negatively influences their daily activities, their working capacity and their well-being (1), thus it is inferred that deterioration in life quality might cause emotional problems to the victims (2). It has been proved that 11% of patients with ophthalmic trauma had faced depression, especially if in long term treatment (3). There is limited literature published about the psychological impact and the quality of life following an eye trauma on patients (2). Visual field and function test analysis do not provide such information (4,5). However, vision loss due to eye trauma may physically, emotionally, psychologically and economically have affected patients, families and society in general (6). Karaman et al (7) mention that parents with children who experienced lens damage were found to be influenced by negative emotions and expressed mild post-traumatic stress disorder.
Furthermore, Lax and Klein (8) reported that work-related eye injuries may cause severe income reduction due to loss of employment and debt increase in order to cover medical and personal expenses while others became uninsured for more than a year. Additionally, most participants mentioned loss of work-related friendships and at the same time some disclosed loss of house or end of their marriage (8). The participants in the present study revealed feelings of loss of dignity and identity and deterioration of self-worth, signs of anxiety, dysthymia, depression and frustration (8). An eye injury is an important life event that can influence patients' emotions, roles within their social network and physical capacity (9). Patients' friends and family have an important role in the rehabilitation process, alongside with system support (9). Multidisciplinary approach is considered vital in order to maximize positive clinical outcomes (9).
The majority of eye injuries refer to men as they tend to be more involved in high risk occupations compared with women (3,10). Additionally, a case series study reported higher risk of ocular injuries at home for individuals with history of an eye condition. The explanation offered stressed that cancellations or postponement of follow-up visits or surgeries and inability to prescribe medicine caused delays in proper treatment (11). Moreover, a number of studies proved that prompt assessment, successful initial management, early presentation to the eye unit (12) and clinical factors were associated with good initial visual acuity (VA) (13), which in turn was a prognostic factor for final visual outcomes (12,14). However, VA has proved inadequate to assess fully the health in general, regarding social, physical and psychological impact on sufferers (1).
The main goal of the present study was to explore factors associated with visual outcomes, in terms of clinical and psychosocial parameters, especially during the period of coronavirus disease 2019 (COVID-19), as restrictive measures of quarantine and commuting led to further access limitation.
Methods
Study design, population and ethics approval
Data of the present study were collected prospectively during an 18-month period between February 1, 2020 and August 31, 2021 from eye injury patients admitted to the General University Hospital of Heraklion Crete, Greece, the only tertiary care center of Crete. The present study included all adult patients that met the following inclusion criteria: i) >18 years, ii) with severe eye injuries presented to the emergency department of Ophthalmology, iii) hospitalized at the ophthalmology clinic either for specialized medical care or treated after surgical intervention. Patients included in the study sample were subjected to standard clinical practice. All socio-demographic information was collected via interview by the researchers during hospitalization. Clinical data were recorded in cooperation with a specialized ophthalmologist who examined each patient at the ophthalmology emergency department until their discharge from the hospital unit. Additionally, it was planned to prospectively record Perceived Stress Scale 14 (PSS-14) levels one year after study end in order to avoid acute phase distress bias and assess any long term effect.
Patients were age grouped between 18-40, 41-66 and ≥67 years. Education included elementary, secondary, high school and university level. A total of four occupation categories were used: Manual workers, farmers/livestock workers, self-employed and private-public sector workers and unemployed. Injuries were grouped into open and closed globe injuries, according to the Birmingham Eye Trauma Terminology (15) and Ocular Trauma Classification Group (16). Visual outcomes were described through initial and final Best Corrected Visual Acuity (BCVA) converted from the Snellen chart to the Logarithm of the Minimum Angle of Resolution (LogMAR) to allow comparisons of different variables (17). The initial and final BCVA were documented on presentation at the ophthalmology emergency department and after outpatient follow-up. It was conventionally labelled as not poor (>0.5/10 or >20/400 on the Snellen scale; <1.3 in LogMAR scale) or poor (≤0.5/10 or ≤20/400 on the Snellen scale; ≥1.3 on the LogMAR equivalent) (18). Admission time to hospital was quantified as ≤2 h and >2 h, while the residence distance (in kilometers) was classified as 0-20, 21-60 and >61 km.
Information on overall psychosocial status of the patients was assessed through a questionnaire sheet for data collection. Most questions were dichotomous (yes/no) while one question was scored by using a Likert scale of 1-10 points, (1, very bad; 5, moderate and 10, good) via telephone interview after a 6-month follow-up period. The same questionnaire collected information about patients' satisfaction regarding the medical service provision, the fear of incident repetition, patients' recovery from the eye trauma and changing work status.
Perceived Stress Scale 14 (PSS-14) is a 14-item tool created by Cohen et al (1983) to measure perceived stress (19). The Greek version of PSS-14 was validated by Andreou et al (20) and uses a Likert-type rating from 0 to 4 (0=never to 4=very often). Higher score indicates higher perceived stress levels after the summation of the items and the reversal of the seven positive questions (20). The scores were grouped into three categories: Low (0-18), moderate (19-37) and high (38-56) (21). All data were collected according to Declaration of Helsinki guidelines to assure confidentiality. The study was also approved by the Scientific Council of the 7th Health District of Crete (protocol no. 17/30-10-2019) and the Scientific Ethics and Deontology Committee of the University of Crete (protocol no. 28/07-02-2020). Verbal and written informed consent was obtained from the patients.
Statistical analysis
All variables were summarized using descriptive statistics. For each variable the number of counts and the respective percentage was presented. Univariate analyses were performed using Fisher's exact test (for binary variables) and Pearson's Chi-square test with Yate's continuity correction (in case of non-binary categorical variables). Means with standard deviation were based on independent samples T-test for the question ‘How well do you currently feel in psychological terms?’, a 10 Likert scale rating. Odds ratios were calculated using simple logistic regression models with final BCVA (not poor vs. poor) as dependent variable. The statistical software used was SPSS version 24 (IBM Corp.). P<0.05 was considered to indicate a statistically significant difference.
Results
The present study covered 30 patients, most of whom were men (76.7%) aged between 41-66 years (56.7%). The majority of participants were Greek (83.3%), had received elementary education (40.0%) and were married (86.7%). As to their occupation, 20.0% were manual workers, 26.7% farmers/livestock workers, while 36.7% were self-employed/private/public sector workers (Table I). Results from Table II indicated that not poor final BCVA was related with not poor initial BCVA [odds ratio (OR) 1.714; P=0.006] and patients with not poor final BCVA did not need surgical intervention (OR 1.500; P=0.042). No significant associations were observed between final BCVA (not poor or poor) and the type of injury, the occupation, the distance from the residence place and the time of admittance to hospital (P>0.05).
The present study compared patients according to their final BCVA (not poor vs. poor). All patients in both groups reported being satisfied with the health care services (100% in both groups). Patients with not poor final BCVA reported significantly improved feelings in terms of psychological status, compared with patients with poor final BCVA (8.36 vs. 6.40; P=0.011).
Patients with not poor final BCVA reported fear of incident repetition to a lesser extent compared with participants with poor final BCVA. The majority of patients (68%) with not poor final BCVA reported recovery from trauma compared with no (0%) patient in the poor final BVCA group (P=0.009).
Hospitalization for eight days or more was more frequent in patients with poor final BCVA compared with patients in the not poor final BCVA group (60 vs. 24%; P=0.143). No patients reported changing their work status and the days of absence from work were similar in both groups.
Patients in the poor final BCVA group reported paying more money in personal expenses (P=0.019) and reported limiting their social activities to a higher extent (100 vs. 52.9%; P=0.050). Finally, the reported PSS-14 scores were significantly higher in patients in the poor final BCVA group (P=0.003; Table III).
Discussion
To the to the best of the authors' knowledge, the present study is the first to explore the psychological status of eye injury patients with visual outcomes in the geographical region of Crete, Greece and there are few published studies on this subject worldwide (2,3). Most of the eye injuries occurred among men, as expected in accordance with other studies (3,12-14). The study revealed that most of eye injuries (36.7%) occurred among self-employed and private-public sector employees, in contrast with studies where most of eye injuries occurred among manual force workers, mainly occupied in farming activities in rural areas (3,10). During COVID-19, self-employment activity might have been increased and available skills might be poor or weakened, a fact that could influence the frequency of such injuries. Work-related eye injuries are considered frequent and therefore it is an issue related to public health (22).
A number of studies proved that the type of injury (3,13), admittance time and the distance from the hospital unit are indicators for visual prognosis (10,12). Manual force workers for instance, or those occupied in agricultural activities exhibit an additional eye injury risk from flying objects (3,10,23,24). In contrast with these studies, the present study found no significant associations between visual outcomes (not poor or poor) and the type of injury, occupation, the distance and the admittance time to the hospital. This is may be due to the fact that most of the injured patients resided permanently near the hospital (0-20 km) or within the prefecture of Heraklion and were admitted in <2 h to the hospital unit. Moreover, during the study period, there were travel bans between the four prefectures of Crete due to COVID-19 restrictions. Therefore, a number of eye traumas were eventually managed in local hospital units and patients did not decide, or were advised, to seek distant care with their own transportation means.
The present study also showed that there was a significant association between initial BCVA and not poor final visual outcomes, in line with other studies (12,14,23), while a retrospective study by Kyriakaki et al (submitted) at the same hospital reported similar results. Additionally, according to the findings presented, patients with not poor final BCVA did not need surgical intervention. The latter finding was in contrast with a study where delayed surgical intervention was reported as a factor related to poor visual outcomes (12). A possible interpretation could be that most of the eye injuries were closed globed, thus less severe and probably were properly managed due to early presentation to the hospital unit.
As shown in Table III, patients with not poor final BCVA reported an improved psychological condition and reported less fear of incident repetition, than those with poor final BCVA (64.0 vs. 100.0%; P=0.286). However, in a study conducted in the UK population, it was found that patients who lost an eye due to severe eye trauma experienced stigmatization and fear of negative social evaluation (25). Additionally, they had an ongoing anxiety of trauma repetition and loss of sight in the healthy eye (25). Working with local communities in order to offer support for individuals with ocular trauma is of critical importance for their recovery.
The findings of the present study indicated that PSS-14 scores were significantly higher in patients with poor final BCVA one year after the study end. To the best of the authors' knowledge, there are limited studies that explore similar associations. However, individuals with dry eye disease (DED) had higher level of perceived stress as measured by PSS (4-item version) in comparison with a non-DED group (26). Moreover, a study about patients with primary open-angle glaucoma, mentioned higher levels of perceived stress were related to lower BCVA in the healthier eye (27). The aforementioned studies refer to chronic eye conditions, however, perceived stress and mental health state repercussions, need to be considered in the management of patients with either eye trauma or chronic ocular conditions.
There is a need to stress that all patients with not poor or poor final BCVA reported being satisfied from healthcare services provision during hospitalization and follow-up, but this association was not significant. To the best of the authors' knowledge, there is limited research regarding patients' satisfaction from healthcare facilities and the way that this satisfaction interact with their feelings in terms of recovery from a severe eye injury and the psychological status during hospitalization or after discharge. Further research should be conducted to cast more light on this issue using appropriately designed tools. The' psychological impact of severe eye injuries should be evaluated and behavioral interventions could be initiated to help sufferers cope with all possible difficulties arisen. The multilevel effect of eye injuries to the patients is clear and should be taken into consideration by policy makers and health providers during the rehabilitation process.
Time of admission or delay is an important factor for the final BCVA and the recovery of the patient, according to a recent retrospective study (28). Most severe eye injury patients reported that they were hospitalized for <8 days (P=0.143). Another study also stressed that patients were hospitalized from 3-5 days for all types of ocular injuries (29). Finally, in the present study no patient needed to change work status following the injury. Most of the patients mentioned that they recovered from their health problem (P=0.009) and so they returned to their duties. Some other patients might not be able to change work activity. In line with a study in Germany, only one patient, with open globe injury, changed work status (30). By contrast, a study in a Turkish population group reported that patients with vision loss had to change their occupation after the injury (31).
The main strength of the present study was that all data were prospectively selected, thus the information was accurate and complete concerning psychosocial outcomes, even after a long period from the eye injury. On the other hand, there were certain limitations to the present study. A number of eye injuries might not be included in the present study as they could have been managed by private ophthalmologists, local secondary or first aid units due to COVID-19 transportation restrictions. However, it is considered that the present study managed to collect more severe injuries as they required specialized treatment at a tertiary University Hospital. In addition, the study sample was limited during the study period and may not be representative for all eye injuries throughout the geographical region of Crete, as there were suspensions of work, again due to COVID-19 protective measures. As concluded by Liang et al (32) in their literature review, the COVID-19 period and the restrictions implemented led to a 67.7% drop in incidents of ocular trauma compared with previous years. Additionally, they mentioned alterations in the categories of eye injuries, since there was an increase in injuries occurring at home and a decrease of eye injuries in other activities such as work-related incidents (32). Furthermore, Anyfantakis et al (33) noted that COVID-19 pandemic revealed the importance of communication and collaboration between the different levels of health care (primary, secondary and tertiary) in order to improve attention to the needs of patients and proposed the active operation of e-communication. That practice could apply to eye trauma patients particularly in cases where transfer to a tertiary hospital is not a feasible option, as it was during the COVID-19 restrictions.
Further studies should be conducted throughout Greece, focusing on special geo-epidemiological features to identify factors related to visual outcomes and the psychological impact on the overall health of patients. Eye care practitioners should pay attention to the psychological needs of the patients, especially those severely injured, and help them cope with implications subsequent to the injury. Referral pathways and collaboration with other professionals could be established to address the needs of patients holistically. Moreover, a system of social interventions should be initiated, in terms of protective strategies and rehabilitation of visual impaired or disabled patients.
In conclusion, not poor initial BCVA was significantly associated with not poor final visual outcomes. Self-employed and workers of private-public sector had increased risk of experiencing an eye injury, despite the non-significant association. Patients with not poor final BCVA had significantly increased levels of positive psychology and low levels of perceived stress. Not poor final BCVA was also correlated to a reduced fear of incident repetition, while all patients with not poor or poor final visual acuity were satisfied from healthcare services provision, with no significant trend. Collaboration between ophthalmologists and mental health professionals is considered important in order to help patients to eliminate the psychological burden that eye injury entails.
