Abstract

Background: This study aims to explore the impact of eye loss and prosthetic eye wear on recreational, occupational and social areas of functioning.

Methods: Two hundred and seventeen anophthalmic patients who had worn a prosthetic eye for at least two years and were older than 16 years responded to an invitation to complete an anonymous questionnaire. Descriptive and inferential statistics were used to investigate differences between variables. Content analysis was used to analyse participants’ open responses.

Results: Participants reported a range of difficulties in occupational, social and recreational areas of functioning. Those who experienced problems in these areas reported stronger negative feelings and were more concerned about their appearance and visual perception than those who had developed strategies to overcome these problems.

Conclusion: This study identified recreational activities, social functioning and workplace activities as the main areas where functional difficulties are experienced by prosthetic eye wearers. The study (often using patients’ own words) describes the impact of unilateral eye loss on these activities and demonstrates how eye loss and prosthetic eye wear can negatively affect anophthalmic patients’ behaviour and cognitive processing. It is important to prepare patients for this and to provide coping strategies that address patients’ appearance and visual perception concerns due to their negative impact on functioning.

Introduction

A prosthetic eye is used to replace a missing natural eye and scleral shell prosthesis fits over a disfigured non-functioning eye [1]. Previous research has established that losing an eye can negatively impact one’s psychological wellbeing. In fact, McBain, Ezra, Rose and New man [2] concluded that a patient’s adjustment to wearing an ocular prosthesis was associated with psychological variables rather than clinical or demographic factors. McBain, et al. [2] also found that prosthetic eye wearers who had a pessimistic outlook, negative self-image and a perceived lack of acceptance from society had poorer psychological wellbeing. Another study investigated the emotional experiences of individuals following eye loss and found that 32% were preoccupied with hiding their disfigurement ‘a great deal’, 22.5% felt sad and 15% felt shy. At least 10% had ‘a great deal’ of feelings of shame, insecurity, fear, inferiority and anger [3]. The most common difficulties of those with facial disfigurement concern social interactions, with affected individuals being subjected to intrusive staring and comments [4].

Almost all the literature on the psychological adjustment of patients living with a prosthetic eye has focused on appearance issues [2,5,6], but when an eye is lost or disfigured, there are also visual perception changes such as impaired depth perception and restricted visual range as well as a need to cope with the inconvenience of wearing a prosthetic eye-in particular mucoid discharge from the eye socket which is reported to affect 91% of anophthalmic patients [7].

Until now, the specific functional impact of eye loss or of wearing an ocular prosthesis has received minimal research attention. This study helps to address this by asking prosthetic eye wearers directly about their experiences of occupational, social and/or recreational difficulties. It is expected that the greater the negative impact on functioning, the greater the negative impact on psychological wellbeing (and vice versa). The study covers current functional impacts as well as those experienced in the past.

The findings of this study will provide greater insight into the practical implications of unilateral eye loss, which will hopefully lead to more targeted psychological support and advice for current and future prosthetic eye wearers.

Materials and Methods

Recruitment

Once the Massey University Human Ethics Committee granted ethics approval, a questionnaire was mailed or emailed to potential participants from the database of the New Zealand Prosthetic Eye Service, a private practice with six clinics spread across the North Island of New Zealand. Of the 540 potential participants contacted about the research (181 via email), 217 completed the questionnaire (40% response rate). All participants were at least 16 years old and had worn an ocular prosthesis for at least 2 years.

Questionnaire

The questionnaire included 29 questions and 5 psychological scales across 4 main categories (demographics, concerns, feelings and problems, psychological scales). This study covers the problems section of the questionnaire, which asked participants if they had any problems in social, occupational and recreational areas of functioning either currently or in the past. This study also draws upon demographic information gathered (age, gender, education, ethnicity, relationship status, occupation, age when eye lost, etiology, duration of prosthesis wear) and participants’ concerns regarding appearance, mucoid discharge and visual perception.

Data analysis

The Statistical Package for the Social Sciences for Mac (version 23) was used to analyze the quantitative data. Independent t-tests were used to analyze differences between: the presence of functional problems (employment, social, recreational) and levels of concern (discharge, appearance, visual perception) and the age at time of eye loss and the presence of functional problems.

Participants’ open responses regarding the functional impacts of eye loss were analyzed using content analysis. This identified descriptive themes within the data and their frequencies [8]. The percentage of responses within each category was computed, with the most commonly occurring responses being viewed as the most important [9]. For this reason, only categories that obtained percentages over 10% were reported in the results.

Results

Participants

The majority of participants were New Zealand European (76%), followed by Maori (13%), other (7%), Asian (3%) and Pacific Islander (1%). Participants’ average age was 58 years. They had worn a prosthetic eye for 27 years on average and 67% were male.

The gender ratio on 67% men in the study population roughly aligns with the 59% men in a larger survey of prosthetic eye wearers in New Zealand [10]. The representation of New Zealand Europeans (76%) and Pacific Islanders (1%) aligns with that in the general population (75% and 0.08% respectively) [11]. however, there is an under representation of Maori (13%) and Asian (3%) ethnicities compared to the general population (16% and 12% respectively) [11], possibly because it was an English language questionnaire.

Demographic effects

On average, participants with social problems lost their eye at a younger age (M = 20.4, SD = 18.74) than those without social problems (M = 32.3, SD = 21.31, p< .001). This may be due to the developmental period of younger people and the importance of belonging to social groups and forming intimate relationships during this time [12]. Participants with social difficulties were also younger at the time of the study (M = 54.2, SD = 13.82) compared to those without difficulties (M = 60.7, SD = 13.83, p = .001). There were no significant relationships between social problems and other demographic measures or with any demographic measures and occupational or recreational problems (p> 0.05).

Functional difficulties of unilateral eye loss

The most common functional difficulties reported by participants were experienced with recreational activities (57%), social functioning (40%) and employment or workplace activities (32.4%).

Recreational activities

Of those participants whose free comments identified problems with recreational activities, 30.5% had stopped playing, or had particular difficulties with ball sports (“Used to play tennis and squash, still possible but very different level, no longer fun for me”), non-ball sports such as swimming and mountain biking, or contact sports(“Would not play rugby in case of further injury”). Twenty six percent commented that their recreational activities were affected by monocular limitations (i.e., reduced peripheral vision and impaired distance perception) (“I am not brilliant anymore at coordination and catching a ball is only average”, “Can’t judge a moving ball”, “Playing pool has become very difficult - judging distance and angles has become very handicapping”). Monocular vision also impacted on other sports or activities (e.g., “I would love to learn to dance, but scared my sight would make me look silly trying to turn etc and not seeing on my right side”, “Horse riding judging speed and distance, also some balance problems”, “Minor problems skiing - have to constantly look to my right to avoid other skiers”).Nineteen percent commented that their recreational activities were affected by fear of their prosthetic eye falling out (e.g., during swimming, surfing, diving, water skiing) and sixteen percent commented that they had successfully adapted to initial difficulties.

Successful adaption’s mentioned by this group included how they developed strategies or used aids to compensate for problems (“Afraid that if I came off my water-ski the eye may pop out. So I wear an eye patch”, “I was scared my eye would fall out in the waves…I have learnt to turn my back on the waves more and close my eyes hard”, “I returned to playing rugby 4 months after I lost my eye, taught myself to catch the high ball, which was a re-aligning problem”). Others avoided the activity, removed their eye, or used aids like underwater goggles.

Participants with recreational difficulties reported significantly stronger negative feelings (M = .70, SD = .92) than those without difficulties (M = .41, SD = .79, p< 0.001). Those with recreational problems were also significantly more concerned about their appearance and visual perception (Table 1).
