Purpose: To analyze the clinical presentation, course, and management in a large cohort of pediatric acute dacryocystitis subjects and to examine whether hospitalization and urgent surgical intervention are indeed mandatory. Methods: A retrospective analysis of all pediatric subjects diagnosed with dacryocystitis at the Children’s Hospital of Philadelphia over a 12-year period (2009–2020). Results: One-hundred sixty-nine pediatric acute dacryocystitis patients were included in this study. Management included admission in 117 cases (69%). Sixty-eight patients (40%) were treated medically with no surgical intervention, 75 cases (44%) required urgent surgical intervention, and 26 additional cases (15%) required surgery due to persistent tearing symptoms after medical management. The urgent procedures included most commonly: 1) endonasal examination and microdebridement of intranasal cysts in 26 cases (35%); 2) probing and irrigation without examination and microdebridement, with or without stent intubation, in 30 cases (40%); and 3) dacryocystorhinostomy (13 endonasal and 4 external) in 17 cases (23%). Conclusions: Management of pediatric acute dacryocystitis should be tailored individually for each case. Hospital admission and early surgical intervention are not mandatory, as 31% of cases resolved without admission, and 56% without early surgical intervention. Although a specific age cutoff is not plausible, hospital admission for younger patients is more commonly advocated. When surgical intervention is indicated, endonasal examination and microdebridement of any associated intranasal cyst and probing with possible stenting are the initial procedures of choice. Dacryocystorhinostomy is reserved for more complex obstructions. Although pediatric acute dacryocystitis is an infection with serious potential problems, when managed appropriately, complications are rare.

Accumulating evidence suggests that neuroinflammation and immune response are part of the sequence of pathological events leading to optic nerve damage in glaucoma. Changes in tissue temperature due to inflammation can be measured by thermographic imaging. We investigated the ocular surface temperature (OST) profile of glaucomatous eyes to better understand the pathophysiology of these conditions. Subjects diagnosed with glaucoma (primary open angle glaucoma [POAG] or pseudo exfoliation glaucoma [PXFG]) treated at the Sam Rothberg Glaucoma Center (11/2019–11/2020.) were recruited. Healthy subjects with no ocular disease served as controls. The Therm-App thermal imaging camera was used for OST acquisition. Room and body temperatures were recorded, and the mean temperatures of the medial cantus, lateral cantus, and cornea were calculated with image processing software. Thermographic images were obtained from 52 subjects (52 eyes: 25 POAG and 27 PXFG) and 66 controls (66 eyes). Eyes with glaucoma had a significantly higher OST compared to controls (mean 0.9 ± 0.3°C, p < 0.005). The difference between the two groups remained significant after adjustment for age, sex, intraocular pressure (IOP) and room and body temperatures. Lens status and topical IOP-lowering medication did not significantly affect OST. A subgroup analysis revealed that the OST was higher among eyes with POAG compared to eyes with PXFG, but not significantly. Differences in the OST between glaucomatous and normal eyes strengthens current thinking that inflammation affects the pathophysiology of glaucoma. Longitudinal studies are warranted to establish the prognostic value of thermographic evaluations in these patients.

Purpose: The ectodermal dysplasias (EDs) constitute a group of disorders characterized by abnormalities in two or more ectodermal derivatives, including skin, hair, teeth, and sweat glands. The purpose of the current study was to evaluate ocular manifestations in pediatric patients with ED. Methods: Retrospective case series including consecutive ED subjects who were treated in the ophthalmology department at the Children’s Hospital of Philadelphia over a 12-year period (2009–2020). Main Outcome Measures were ocular and ocular adnexal abnormalities. Results: Thirty subjects were included: 20 males (67%), mean age of 4.5 years (range 0.3–18). Patients with different subtypes were included, with the hypohidrotic ED and ectrodactyly-ectodermal dysplasia-clefting variants being most prevalent. Most common findings were: lacrimal drainage obstruction in 12 (40%) including punctal agenesis in 10 (33%), refractive errors in 13 (43%) and amblyopia in 6 (20%). A new finding of eyelid ptosis or eyelash ptosis was demonstrated in 11 subjects (37%), mostly associated with TP63 or EDA1 genes variants. Conclusion: Ectodermal dysplasias are associated with various ocular pathologies and amblyopia in the pediatric population. We report a possible genetic association between lash ptosis and EDA1 gene, and eyelid ptosis and TP63 or EDA1 genes variants.
