The impact of topical treatment for chalazia on the odds of procedural management.

Chalazia in pediatric patients are often treated with topical antibiotics or steroids, although no strong evidence supports their use. This retrospective review of pediatric patients with chalazia did not find a decreased odds of undergoing procedural treatment (incision and curettage and/or intralesional steroid injection) with initial topical antibiotics and/or steroids compared to conservative measures. Inflamed chalazia may benefit from topical treatment, but small sample size limits this subgroup analysis. Shorter pre-topical treatment chalazion duration correlated with a lower risk of procedural intervention. Regimens that included steroids were not found to be more effective than topical antibiotics alone.

Overhead Mounted Optical Coherence Tomography in Childhood Glaucoma Evaluation.

PRéCIS:: Overhead mounted spectral-domain optical coherence tomography (OCT) enables high-quality imaging of the optic nerve and macula in childhood glaucoma, and is particularly useful when standard tabletop OCT has failed or is not possible. PURPOSE: Tabletop OCT, integral to adult glaucoma management, can be limited in childhood glaucoma patients because of young age, poor cooperation, and/or technical challenges. To address these imaging difficulties, we determined the feasibility and quality of an overhead mounted unit in childhood glaucoma. Secondary aims included evaluation of peripapillary retinal nerve fiber layer (pRNFL), parafoveal total retinal thickness, and parafoveal ganglion cell complex (GCC) thickness. MATERIALS AND METHODS: Children and adults with a diagnosis of childhood glaucoma were imaged with an overhead mounted spectral-domain OCT as part of a prospective cross-sectional study. Participants had poor quality or unobtainable tabletop OCT and were scheduled for an examination under anesthesia and/or surgery as part of standard care. RESULTS: A total of 88 affected eyes in 60 of 65 (92.3%) enrolled patients (mean age, 5.9±5.9 y; range, 0.2 to 24.5) were successfully imaged. The mean image quality for analyzed scans was 22.9±6.0 dB (n=236 images). Mean values for pRNFL (80.5±31.0 µm; n=86), parafoveal total retinal thickness (301.10±39.9 µm; n=79), and parafoveal GCC thickness (96.0±21.6 µm; n=74) were calculated. CONCLUSIONS: Overhead mounted OCT allowed high-quality image acquisition and analysis in childhood glaucoma patients unable to be imaged with the tabletop counterpart, presenting an opportunity for improved clinical management and study of childhood glaucoma-related pathophysiology. pRNFL, parafoveal total retinal thickness, and parafoveal GCC thickness were decreased for affected eyes of children under 6 years of age compared with age-matched controls from a companion normative study.

Optical Coherence Tomography Normative Peripapillary Retinal Nerve Fiber Layer and Macular Data in Children 0-5 Years of Age.

PURPOSE: To determine reference values for the peripapillary retinal nerve fiber layer (pRNFL) and macula in children 0-5 years of age. DESIGN: Prospective cross-sectional study. METHODS: This study was set in a single large academic pediatric ophthalmology practice. Healthy, full-term children 0 to <6 years of age presenting for surgery under general anesthesia were prospectively recruited for participation. Excluded were children with systemic neurologic disease, optic nerve or retinal disease (even if unilateral) or any bilateral ocular disease process, and eyes with amblyopia, ocular disease, or spherical equivalent refractive error outside of -3.00 to +8.00 diopters. Following general anesthesia, OCT scans of the optic nerve and retina were acquired using an HRA+OCT Spectralis with Flex module (Heidelberg Engineering). Automated segmentation of the pRNFL and retinal layers was followed by manual correction. RESULTS: Data were obtained from normal eyes of 57 participants (mean age 2.28 ± 1.50 years). Mean global pRNFL thickness was 107.6 ± 10.3 µm. Mean global pRNFL thickness was not dependent on age but showed a negative relationship with axial length (P = .01). The mean total macular volume was 8.56 ± 0.259 mm3 (n = 38). No relationship was found between total macular volume and age. Ganglion cell layer, ganglion cell complex, and inner nuclear layer volumes showed an inverse relationship with age while the photoreceptor layers showed a logarithmic increase with age. CONCLUSIONS: Global pRNFL thickness measurements remain stable over time. Macular volume and thickness values of segmented retinal layers reflect the development of the macula with age.

Postoperative infection following strabismus surgery: case series and increased incidence in a single referral center.

PURPOSE: To identify and analyze cases of postoperative infection following strabismus surgery at a large referral center and to report the incidence, risk factors, and outcomes. METHODS: An electronic database search identified strabismus procedures at Duke Eye Center from July 1996 to October 2017. Diagnosis codes for periocular infections were used to further identify patients with possible infections following strabismus surgery. RESULTS: Of 9,111 strabismus surgeries, 13 (0.14%) met criteria for probable infection, all occurring since October 2012 (0/6580 before vs 13/2531 [0.51%] after; P < 0.0001). Mean age of infection cases was 11.4 years; 11 patients (85%) were under 18 years of age. Associated previous diagnoses were genetic abnormalities with associated developmental delay (n = 5 [38%]), previous skin or ear infection (n = 4 [31%]), and acute or chronic rhinitis (n = 3 [23%]). Infection site cultures revealed methicillin-resistant Staphylococcus aureus (n = 3 [23%]), methicillin-sensitive S. aureus (n = 3 [23%]), and Streptococcus pyogenes/group-A Streptococcus (n = 2 [15%]). Only 1 case had bilateral infection. Infection remained extraocular in all cases, but one eye lost light perception secondary to optic atrophy. No common surgeon/procedure/preparation-related risks were identified. CONCLUSIONS: A unifying explanation for the increase in post-strabismus surgery infections at Duke Eye Center was not identified. Potential risk factors include age <18 years, developmental delay, immune compromise, preceding nonocular infection, and bacterial colonization.

Home tonometry in childhood glaucoma: clinical indications and physician and parental attitudes.

Home rebound tonometry is a beneficial tool for the management of childhood glaucoma, yet is not commonly used. In this study, 29 childhood glaucoma patients were recruited for twice daily home intraocular pressure (IOP) monitoring using an Icare rebound tonometer. Home rebound tonometry data prompted and/or validated glaucoma-related surgery in 16 patients (55%) and medication change in 22 patients (76%). According to survey responses, 84% of parents or patients (n = 83) would be interested in home tonometry, and 80% of physicians (n = 48) agreed that home tonometry would improve their ability to manage patients; however, only 14% of physicians currently lend tonometers for this purpose, largely due to financial concerns.
