Multimodal Imaging of Posterior Corneal Opacities in Multicentric Osteolysis Nodulosis and Arthropathy (MONA).

Purpose: Multicentric osteolysis nodulosis and arthropathy (MONA) syndrome is a rare autosomal recessive skeletal dysplasia. Caused by mutations in the matrix metalloproteinase 2 gene () on chromosome 16q12, this syndrome has infrequently been associated with ophthalmic manifestations. Corneal opacities have been reported but not described or documented in detail.

Iris Heterochromia in Acquired Horner Syndrome Following Surgical Excision of Parapharyngeal Neuroblastoma.

This report describes an infant who developed iris heterochromia 2 years after presenting at age 2 months with acquired Horner syndrome following excision of a parapharyngeal neuroblastoma. Iris heterochromia is classically associated with congenital, not acquired, Horner syndrome due to a disruption of the oculosympathetic pathway early in life that alters iris melanocyte migration, leading to an ipsilateral lighter colored iris compared to the fellow iris. In the case reported here, the disruption to the oculosympathetic pathway occurred so early in life that normal iris melanocyte migration was impacted on the affected side, leading to eventual iris heterochromia that was noted almost 2 years later.

Bilateral primary orbital xanthogranulomas: A case report and comparison of xanthomatous conditions.

This report describes an unusual and diagnostically challenging case of subcutaneous soft tissue xanthogranulomas of bilateral orbits of a 58-year-old female patient seen in a private oculoplastics practice. Accurate and timely diagnosis is crucial in xanthogranulomatous diseases so that any systemic manifestations can be identified and addressed in a multidisciplinary fashion. Periorbital xanthogranuloma is a frequent early manifestation of adult xanthogranulomatous disease, and its association with life-threatening systemic disease requires accurate diagnosis and prompt work-up.

Accuracy of a universal theoretical formula for power calculation in pediatric intraocular lens implantation.

Purpose: To compare the accuracy of Barrett Universal II formula with other formulas (Holladay 2, Hoffer Q, and SRK/T formulas) in the prediction of postoperative refraction for pediatric intraocular lens implantation.

Setting: Academic medical center/children's hospital, San Francisco, California.

Design: Retrospective case series.

Purpose: To identify the characteristics that are associated with adherence to annual diabetic eye exams and patient awareness of retinopathy using a nationally representative sample from the United States.

Design: Cross-sectional, secondary analysis.

Participants: National Health and Nutrition Examination Survey (NHANES) participants from 2005 to 2016 aged 20 years and older with diabetes mellitus.
