Objective: To investigate the effectiveness of information transfer by the pediatric cataract surgeon to the parents or guardians of children during the informed-consent process., Design: Prospective observational case series., Participants: Parents of 31 children undergoing cataract surgery., Methods: Parents were enrolled from the clinical practice of 1 pediatric cataract surgeon. Using a checklist developed in consultation with other pediatric cataract surgeons, the surgeon discussed the nature of the disease, the course without surgical intervention, the surgical procedure, the risks and benefits, and the postoperative care. Immediately after the discussion, parents were invited to complete a questionnaire assessing information recall. Analysis of variance and the t test were used to determine associations between questionnaire scores and demographic variables. The surgeon subsequently called parents and discussed again the issues that they had not remembered correctly, as identified by the questionnaire responses. The study and data accumulation were carried out with the approval of the Research Ethics Board at The Hospital for Sick Children, Toronto, Ont. Informed consent for the research was obtained from the parents or legal guardians of the children enrolled in the study. The study adhered to the tenets of the Declaration of Helsinki., Results: Of 31 parents, 18 (58%) overestimated their understanding of the informed-consent discussion. Parents scored well on questions about the nature of the disease and the postoperative follow-up but scored lower on questions regarding surgical risks and outcomes. Parents identified several barriers to understanding, including the large amount of information, stress, and preoccupation with the child. No association was noted between the level of understanding and demographic factors., Conclusions: Parents may overestimate their understanding of informed-consent discussions. Some parents may be overly optimistic about risks and outcomes. The surgeon's follow-up communication with parents that addressed aspects insufficiently understood during the initial discussion provided a way of improving comprehension., (Copyright © 2012.

Purpose: To ascertain the interobserver agreement among various specialists when analyzing images of the optic nerve head taken with the RetCam 120 (Clarity Medical Systems, Inc., Pleasanton, CA) for assessing the progression of optic disk cupping in pediatric glaucoma. Methods: Five observers compared pairs of RetCam 120 two-dimensional photographs from 64 eyes to identify whether or not changes in the optic disk had occurred. Observers included a pediatric glaucoma specialist, pediatric neurophthalmologist, strabismologist, pediatric ophthalmic imaging specialist, and pediatric ophthalmology fellow. Each was masked to the patient identity and clinical course. For each patient, the observers reviewed the photographs taken prior to therapy and at a minimum of 6 months following initiation of therapy. Interobserver variability was calculated and analysis conducted to identify influential variables. Results: Poor agreement was noted between the observers. No significant association was obtained between agreement level and variables affecting photographic quality: variability of contrast and illumination, exposure and magnification, image clarity, presence of fluorescein on the cornea, and pixelation of the image with poor resolution. Raters noted problems with these image variables in 75.6% of the observations. The Kappa statistic obtained was κ = 0.29 with overall proportion of agreement of p = 0.69, suggesting a fair agreement but not a moderate agreement. Conclusions: Comparison of RetCam 120 pediatric optic nerve head photographs, when performed subjectively by observers with different perspectives, and in isolation from clinical information, may not be a reliable indicator of cupping change. In addition, variations in image contrast, luminance, color, and pixelation pose significant challenges to agreement between observers. Comparison of RetCam 120 images should not be considered the sole criterion for monitoring pediatric glaucoma. [Copyright &y& Elsevier]
