The psychological impact of eyedrops administration in children

Captains on call: A qualitative investigation of an intervention to support children with retinoblastoma undergoing regular eye examinations

BACKGROUND

Retinoblastoma is a rare childhood ophthalmic cancer that requires frequent eye examinations under anaesthesia and painful or distressing procedures. This can cause significant anxiety for children and their families.

OBJECTIVE

We evaluated a Starlight Children's Foundation programme, 'Captains on Call', at the Queensland Children's Hospital, which aims to provide positive distraction and reduce stress, anxiety and pain during the perioperative journey for children in the retinoblastoma treatment pathway. This study examined the impact of the programme on the perioperative experience of the children and their families, using a qualitative design.

METHODS

This study was conducted in a paediatric operating suite at a tertiary-level children's hospital in Australia. We interviewed a parent from 20 families (from a cohort of 40 families, including 44 children), whose children received treatment or screening for retinoblastoma, focusing on the programme's impact on the child and family at various stages during the perioperative journey. We undertook a thematic analysis of transcribed interviews.

RESULTS

We identified two themes, each with two sub-themes: (1) the programme positively contributed to the overall treatment journey, by addressing different needs at different times, and helping to reframe a traumatic medical experience, and (2), the programme supported the whole family unit by empowering children through play, and adopting a family systems approach which recognised the impact of cancer treatment on the whole family.

CONCLUSION

This study highlights the value of the Captains on Call programme in supporting children with retinoblastoma and their families during perioperative visits. The Captains, particularly as non-medicalised professionals in a healthcare setting, built trust and rapport with the children through play over repeated episodes of care. The interprofessional collaborative approach with a reflective cycle of practice extended it beyond a programme providing simple distraction. Other retinoblastoma services may benefit from implementing a similar approach.

Safety, adherence and discontinuation in varenicline solution nasal spray clinical trials for dry eye disease

Aim: Herein, we report safety outcomes for varenicline solution nasal spray (VNS) within the context of clinical trial discontinuation, contrasting those with discontinuation outcomes from topical cyclosporine and lifitegrast clinical trials. Materials & methods: 1061 subjects were randomized across three clinical trials to receive either VNS 0.06 mg, VNS 0.03 mg, VNS 0.006 mg or vehicle control. Subjects who discontinued from treatment were noted and assigned to their appropriate categories. Results: Despite treatment emergent adverse events, 93.5% of subjects receiving VNS completed the treatment period. By comparison, only 80% of subjects in the integrated clinical trials for cyclosporine ophthalmic emulsion and 91% of subjects in the integrated trials for lifitegrast ophthalmic solution completed the full treatment period, respectively. Conclusion: In clinical trials, VNS demonstrated improvements in dry eye disease signs and symptoms, was well-tolerated, and had an overall completion rate >93%. Conventional dry eye treatments (e.g., cyclosporine and lifitegrast) noted considerably higher discontinuation rates in their clinical trials.

Medication Adherence and Common Barriers for Caregivers of Preschool Children with Pediatric Glaucoma

Purpose. To investigate the medication adherence among caregivers of preschool children with pediatric glaucoma and to elucidate common barriers leading to poor adherence. Methods. A cross-sectional study. Caregivers of preschool children with pediatric glaucoma completed a questionnaire on demographic information of caregivers, demographic and disease characteristics of children, caregivers-reported medication adherence (by an adapted Morisky Adherence Scale), and possible 13 barriers. Results. Overall 132 questionnaires were considered valid. Thirty-six percent of all reported poor medication adherence. Caregivers’ age and self-evaluated knowledge about pediatric glaucoma showed a significant difference between the adherent and nonadherent groups ( $P<0.05$ ). Nineteen percent of all reported only one barrier as important, 65% cited multiple barriers, and 16% cited no barriers. Anxiety and depression were cited as important by most caregivers in both groups. Univariate logistic regression analysis demonstrated that difficulty with the acquisition of medications (OR, 2.5; 95% CI, 1.1–5.7; $P=0.025$ ), difficulty with medication schedule (OR, 2.3; 95% CI, 1.0–5.0; $P=0.043$ ), and high expenses for medications (OR, 4.8; 95% CI, 1.4–15.9; $P=0.011$ ) were significantly associated with higher odds of poor adherence. Conclusions. Over one-third of caregivers of preschool children with pediatric glaucoma were in poor medication adherence. Nearly two-thirds of caregivers cited multiple barriers simultaneously as important hindrances to medication usage. Anxiety and depression, difficulty with the acquisition of medications, difficulty with the medication schedule, and high expenses for medications were prominent barriers. Individualized solutions should be provided according to reported barriers by each caregiver and the other most common barriers.

Strabismus Surgery Infection Prophylaxis and Timing of First Postoperative Visit

PURPOSE

To characterize the practice patterns of pediatric ophthalmologists regarding infection prophylaxis for strabismus surgery and timing of the first postoperative visit.

METHODS

A ten-question multiple-choice, close-ended questionnaire was e-mailed to members of the American Association for Pediatric Ophthalmology and Strabismus listserv. Survey responses were summarized using frequencies and percentages. Univariable tests of association between prophylactic measures and surgeons reporting a prior episode of postoperative cellulitis or endophthalmitis were performed.

RESULTS

Three hundred eighty pediatric ophthalmologists completed the survey. Most ophthalmologists instill 5% povidone-iodine solution during surgical preparation (88.4%), use topical antibiotics with or without steroids at the conclusion of surgery (90%), and prescribe oral or topical antibiotics postoperatively (85.5%). Eighty-five percent of strabismus surgeons routinely see patients for the first postoperative visit within the first week, although there is no consensus as to which day is preferred. Responders previously reporting experience with a postoperative infection were more likely to use intraoperative intravenous antibiotics (P = .002) and Tegaderm tape (3M, St. Paul, MN) or other adhesive drape to isolate the eyelids/eyelashes (P = .047).

CONCLUSIONS

A common practice pattern appears to exist regarding the use of 5% povidone-iodine solution in surgical preparation, application of topical antibiotics at the end of surgery, and a postoperative regimen of topical antibiotics/steroids. There is no prevailing practice pattern regarding the timing of the first postoperative visit. Previous experience with postoperative cellulitis or endophthalmitis may lead to the adoption of more formidable infection prophylaxis measures such as intravenous antibiotics prior to surgery.

Factors Affecting Pupil Reactivity After Cycloplegia in Asian Children

PURPOSE

The aim of this study was to evaluate the factors affecting cycloplegia, as determined by pupil reactivity, in Asian children.

DESIGN

Prospective observational study.

METHODS

Two-hundred sixty-eight children, aged 2 to 12 years, requiring cycloplegic refraction, were recruited. Nurses instilled 2 to 3 cycles of eye drops consisting of cyclopentolate 1%, tropicamide 0.5%, and phenylephrine 2.5%, and recorded the child's level of cooperation. Optometrists recorded pupil reactivity after the last cycle. Multivariate analysis determined factors affecting pupil reactivity including age, sex, race, number of eye drop cycles, pupil sizes before and after cycloplegia, and child's cooperation during eye drops instillation.

RESULTS

The pupils in 36 children (13.4%) were found to be still reactive. On univariate analysis, children with reactive pupils also had smaller pupils after cycloplegia (6.27 ± 1.16 mm vs 7.42 ± 0.81 mm, P < 0.001). On multiple logistic regression analysis, for every 1-mm increase in the pupil size after cycloplegic eye drop administration, the odds of having reactive pupils decreases by 65% (odds ratio = 0.35, 95% confidence interval 0.25-0.51, P ≤ 0.001). Those who were uncooperative during administration of eye drops were 3.13 times more likely to have reactive pupils (95% confidence interval 1.21-8.13, P = 0.019), whereas age (P = 0.904), sex (P = 0.355), the number of cycles of eye drops (P = 0.462), and other psychological factors were not relevant in affecting pupil reactivity.

CONCLUSIONS

Pupil reactivity, which was used as a measure of cycloplegia, was more likely to be affected by children's level of cooperation during instillation of eye drops, rather than age and sex. Two cycles of eye drops were as effective as 3 cycles in producing cycloplegia.

Dexamethasone Drug Eluting Nanowafers Control Inflammation in Alkali-Burned Corneas Associated With Dry Eye

Purpose

To evaluate the efficacy of a controlled release dexamethasone delivery system for suppressing inflammation in an ocular burn + desiccating stress (OB+DS) model.

Methods

Nanowafers (NW) loaded with Dexamethasone (Dex, 10 μg) or vehicles (2.5% Methylcellulose; MC) were fabricated using hydrogel template strategy. C57BL/6 mice were subjected to unilateral alkali ocular burn with concomitant desiccating stress for 2 or 5 days and topically treated either with 2 μL of 0.1% Dex or vehicle four times per day and compared with mice that had MC-NW or Dex-NW placed on their corneas. Clinical parameters were evaluated daily. Mice were euthanized after 2 or 5 days. Quantitative PCR evaluated the expression of inflammatory cytokines IL-1β and IL-6 and matrix metalloproteinases (MMP) in whole cornea lysates. Myeloperoxidase activity (MPO) was measured using a commercial kit in cornea lysates.

Results

Both Dex drop and Dex-NW groups had significantly lower corneal opacity scores compared with their vehicles. Both Dex drops and Dex-NW significantly decreased expression of IL-1β, IL-6, and MMP-9 RNA transcripts compared with vehicle drops or wafers 2 and 5 days after the initial lesion. A significant lower number of neutrophils was found in both Dex treatment groups and this was accompanied by decreased MPO activity compared with vehicle controls.

Conclusions

Dex-NW has efficacy equal to Dex drops in preserving corneal clarity and decreasing expression of MMPs and inflammatory cytokines of the corneas of mice subjected to an OB+DS model.
