Childhood cone-rod dystrophy with macular cyst formation in mutation identified by serial spectral-domain optical coherence tomography.

Cone-rod dystrophy (CORD) is a type of progressive hereditary retinal dystrophies that causes cone predominant photoreceptor degeneration characterized by wide genotypic and phenotypic heterogeneity. Macular cyst (MC) occurs very infrequently in the pediatric age group and has rarely been described in CORD. We report a case of young-onset CORD that was affected by an isolated mutation complicated by the development of MC.

Orbital hybrid peripheral nerve sheath tumors.

Hybrid peripheral nerve sheath tumors (HPNST) are recently classified tumors from the World Health Organization Classification of soft tissue tumors that display combined features of more than one peripheral nerve sheath tumor. Acknowledgment is important because of its association with the development of neurofibromatosis type 1, type 2, and schwannomatosis. Orbital involvement is rare and only six cases of HPNST have been documented on literature.

Immunoglobulin G4-related lacrimal sac dacryocystocele: A novel case report.

Purpose: Immunoglobulin G4-related disease is a systemic fibroinflammatory disease of unknown etiology. Immunoglobulin G4-related ophthalmic disease (IgG4-ROD) can manifest in multiple ways, but lacrimal sac involvement is rare. We present the first case in Chinese population of lacrimal sac IgG4-ROD.

Primary recurrent orbital schwannoma treated with surgical excision and Mitomycin-C.

Purpose: Primary orbital schwannoma (POS) is a slow growing, benign encapsulated peripheral nerve sheath tumor that occurs infrequently within the orbit. Recurrence of POS is extremely rare. Previous speculations for reasons of recurrence include incomplete excision and tumor seeding.

Identification of a possible association of JAK2 in development of microphthalmia, anophthalmia, and coloboma (MAC) complex in a child with 9p deletion and duplication.

Background: Microphthalmia, anophthalmia, coloboma (MAC) complex is a spectrum of ocular abnormalities that occur in isolation or as part of a syndrome. Genetic abnormalities have been shown to account for 80% of cases in bilateral anophthalmia or severe microphthalmia, where 25-30% were attributed to chromosomal defects in this subset of MAC patients. To date, chromosome 9 short arm (9p) abnormalities have not been shown to associate with development of MAC.

Improper Use of the Germicidal Range Ultraviolet Lamp for Household Disinfection Leading to Phototoxicity in COVID-19 Suspects.

Purpose: To report the germicidal range ultraviolet (UV) irradiation-induced phototoxicity because of unprotected exposure to the UV lamps for presumed household disinfection of SARS-CoV-2 in a domestic setting.

Methods: We report on a family of 3 adults who experienced photophobia, intense eye pain, epiphora, blurred vision, and a burning sensation over the face and neck area after a short period of unprotected exposure to the UV germicidal lamps.

Results: An initial examination revealed erythema and tenderness over the face and neck area, reduced visual acuity of 6/12, and conjunctival injections bilaterally in all 3 patients.

Ophthalmic Manifestation of Tsukamurella Species: A Case Series and First Report of Ocular Implant Infection After Enucleation.

Purpose: Tsukamurella is an important and emerging organism that causes opportunistic human infection. We present the largest case series of Tsukamurella species-associated ophthalmic infections, with an emphasis on clinical spectrum, risk factors, treatment, and outcome.

Methods: A case series of culture-positive Tsukamurella species in ocular microbiological specimens was identified retrospectively from 2005 to 2018.
