    Abstract Purpose: To evaluate the usefulness of measuring orbital fat density in identifying post-septal involvement when initial differential diagnosis between orbital and periorbital cellulitis (OC and POC) is unclear.
    Materials and methods: Retrospective study of patients with clinical diagnosis of OC or POC who underwent contrast-enhanced computerized tomographic scans over a span of 10 years. Intraconal orbital fat density was measured with Hounsfield units (HU) in six areas on axial scans consisting of nasal and temporal intraconal sites. These measurements correlated with the initial and final diagnoses. Main outcome measures were HU values at the initial and final diagnoses.
    Results: Fifty-seven patients were included. Mean HU measurement was -52 ± 18 HU for the involved side vs. -63 ± 13 for the uninvolved side (
    Conclusion: Intraconal fat density measurements can assist in the primary assessment of orbital involvement in patients with an uncertain initial diagnosis, with a HU value higher than -50 is suggestive of orbital involvement.

    Abstract Objectives: Koolen-de Vries Syndrome (KdVS) is a rare multisystem neurodevelopmental disorder. Ocular manifestations, including strabismus, ptosis, and hyperopia, have been reported in KdVS patients, but detailed clinical data are limited. This study aims to investigate the already known ocular malformations and their frequency while uncovering novel ocular associations.
    Methods: This was an international cross-sectional study. An anonymous questionnaire was sent to 237 KdVS patients registered in the GenIDA database. The questionnaire inquired about demographic data, ocular symptoms, findings reported by ophthalmologists, and ophthalmologic surgical interventions. The main outcome measures included ocular findings and surgical interventions.
    Results: Sixty-seven respondents worldwide completed the questionnaire, most (n = 53; 79%) under 18 years of age. Ophthalmologic abnormalities, noted in 79% of patients, included refractive errors (n = 35; 52.2%), strabismus (n = 23; 34.3%), amblyopia (n = 13; 19.5%), and eyelid ptosis (n = 9; 13.4%). Lacrimal disorders were present (n = 6; 9.0%), as were retinal findings (n = 7; 10.4%), including retinal hyperpigmentation or hypopigmentation (n = 4; 7.5%), Sjögren's pigment epithelial reticular dystrophy (n = 1; 1.5%), and macular chorioretinal coloboma (n = 1; 1.5%). Other manifestations included ocular surface disorders (n = 5; 7.5%), cataracts (n = 3; 4.5%), Brown syndrome (n = 1; 1.5%), glaucoma (n = 1; 1.5%), cerebral visual impairment (n = 1; 1.5%), and optic atrophy (n = 1; 1.5%). Fourteen patients (20.8%) had undergone surgical interventions.
    Conclusions: KdVS is associated with various ophthalmic findings, such as amblyopia, refractive errors, strabismus, and eyelid ptosis. We describe, for the first time, a high rate of nasolacrimal disorders and retinal abnormalities consisting mainly of pigmentary findings, including a rare case of Sjögren's pigment epithelial reticular dystrophy. A comprehensive ophthalmic evaluation is therefore recommended for all KdVS patients at initial diagnosis or at 4-6 months of age for diagnosed newborns.

    Abstract Prcis: Ahmed glaucoma valve (AGV) implantation without plate fixation resulted in high rates of complications related to plate or tube movement.
    Purpose: Scleral suturing of the plate of AGV is associated with technical difficulty and potential complications. This study summarizes the surgical outcomes of 10 years of experience with AGV implantation without suture plate fixation.
    Methods: The medical records of all glaucoma patients who underwent AGV implantation surgery without plate fixation between 2009 and 2019 at the Sheba Medical Center (Tel Hashomer, Israel) were retrospectively reviewed. Clinical data on intraoperative and postoperative complications, best-corrected visual acuity, intraocular pressure, and number of intraocular pressure-lowering medications were retrieved.
    Results: Included were 95 eyes of 95 patients (53 men, 42 women; mean age, 54.9±17.5 y). The mean follow-up was 687±673 days. In total, 37 patients (37/95, 38.%) had AGV-related complications, of whom 28 (29.5%) required additional intervention. Women had a significantly higher rate of complications than men (21/42, 50% vs. 16/53, 30.2%, respectively, P=0.049). The 2 most common complications were AGV migration in 13 eyes (13.7%) and tube exposure/AGV extrusion in 9 eyes (9.5%). AGV was removed in 10 cases.
    Conclusions: In this cohort, omitting suture AGV plate fixation resulted in high rates of complications related to plate or tube movement, the need for further intervention, and AGV removal. Therefore, we cannot recommend this surgical technique.
