The Impact of an Ocular Prosthesis on the Quality of Life, Perceived Stress, and Clinical Adaptation of Anophthalmic Patients: A Clinical and Longitudinal Trial

Analysis of microbial communities of ocular prostheses and anophthalmic sockets using 16S rRNA gene sequencing

Ocular prostheses are liable to host microbial adhesion, which can favor conjunctival inflammation. Knowing the microbiota of the ocular prosthesis and anophthalmic socket is important for predicting infection-related pathogens. This study evaluated the microbiota of the prostheses and anophthalmic sockets of six individuals by 16S rRNA sequencing. The microbial abundance and diversity were analyzed using the Operational Taxonomic Units at the genus level. Forty-seven phyla, capturing 1,258 named genera, were recorded in the sample set. In both sites, the most frequent genera were Fusobacterium, Staphylococcus, Prevotella, and Streptococcus. The microbial abundance was higher for the anophthalmic socket than for the prosthesis. Alpha diversity showed no significant differences in bacterial richness or diversity between sites. Although the microbial abundance in the anophthalmic socket was higher, both sites had similar microbiota with high diversity and low dominance among the genera.

Conjunctival sac microbiome in anophthalmic patients: Flora diversity and the impact of ocular prosthesis materials

Purpose

To explore the changes of bacterial flora in anophthalmic patients wearing ocular prosthesis (OP) and the microbiome diversity in conditions of different OP materials.

Methods

A cross-sectional clinical study was conducted, involving 19 OP patients and 23 healthy subjects. Samples were collected from the upper, lower palpebral, caruncle, and fornix conjunctiva. 16S rRNA sequencing was applied to identify the bacterial flora in the samples. The eye comfort of each OP patient was determined by a questionnaire. In addition, demographics information of each participant was also collected.

Results

The diversity and richness of ocular flora in OP patients were significantly higher than that in healthy subjects. The results of flora species analysis also indicated that in OP patients, pathogenic microorganisms such as Escherichia Shigella and Fusobacterium increased significantly, while the resident flora of Lactobacillus and Lactococcus decreased significantly. Within the self-comparison of OP patients, compared with Polymethyl Methacrylate (PMMA), prosthetic material of glass will lead to the increased colonization of opportunistic pathogens such as Alcaligenes, Dermabacter and Spirochaetes, while gender and age have no significant impact on ocular flora.

Conclusions

The ocular flora of OP patients was significantly different from that of healthy people. Abundant colonization of pathogenic microorganisms may have an important potential relationship with eye discomfort and eye diseases of OP patients. PMMA, as an artificial eye material, demonstrated potential advantages in reducing the colonization of opportunistic pathogens.

Clinical Congenital Anophthalmos and Microphthalmos-Experiences of Patients and Their Parents after More than 10 Years of Treatment

Congenital clinical anophthalmos and blind microphthalmos describe the absence of an eye or the presence of a small eye in the orbit. Between 1999 and 2013, 97 children with anophthalmos or microphthalmos were treated with self-inflating, hydrophilic gel expanders at the Rostock Eye Clinic. More than a decade later, this study investigated the perspective of patients and parents regarding the treatment, the surgical outcome, and the emotional and social well-being of the patients. A total of 22 families with 16 patients sighted in the other eye and six patients blind in both eyes participated. Questionnaires were developed, including items on physical, emotional, social, and medical aspects. The patients felt emotionally stable and integrated into their social environment, with no major limitations reported by the majority. These statements were confirmed by most of the parents. Parents (67%) indicated that the success of the operation was already apparent after the first intervention and that the current situation did not play a role in the patients' social environment. The study provided new insights into the therapy results, the postoperative care, and the social and emotional stability of the prosthesis-wearing patients, indicating the chosen expander methods as promising in terms of positive postoperative care.

Psychosocial distress and psychological adjustment in patients with ocular loss: a framework analysis

BACKGROUND

Patients with ocular loss tend to have physical and psychosocial difficulties. Maxillofacial prosthetic specialists involved in the treatment should be trained with competence to manage psychological complications. However, due to the multifactorial origin of the psychosocial distress, designing such training activities can be challenging. This research aimed to construct a conceptual framework illustrating the effects of ocular loss on patients' physical and psychosocial well-being and their coping strategies, to propose the learning content of training sessions.

METHODS

A semi-structured interview and a topic guide were employed to explore the perceptions from patients who were receiving their first custom ocular prosthesis, fabricated by maxillofacial prosthodontists. The participants were selected using a purposeful sampling up until data saturation. The data were analyzed using framework analysis.

RESULTS

Twelve patients participated in this research. Four main themes emerged from the data analysis: (1) Impact of ocular loss, (2) Factors influencing psychosocial distress, (3) Psychological adjustment, and (4) Expected treatment outcomes. Each theme appeared to have influence on the other, rather than presenting itself independently. Although patients with ocular loss experienced both physical and psychosocial difficulties, psychological distress was greatly influenced by self-perceived disfigurement, etiology, and social status. Therefore, they needed to develop their coping strategies including rehabilitation with ocular prosthesis.

CONCLUSION

Various forms of psychological adjustments were necessary in these patients with ocular loss to resume their daily lives. The specialist involved in the treatment should also partake in patients' psychological adjustment and should be competent in psychological management skills, such as supporting patients to meet their expectations.
