CHARACTERISTICS OF PERIPAPILLARY INTRACHOROIDAL CAVITATION IN HIGHLY MYOPIC EYES: The Zhongshan Ophthalmic Center-Brien Holden Vision Institute High Myopia Cohort Study.

Purpose: To characterize peripapillary intrachoroidal cavitation (PICC) in highly myopic participants and its associated risk factors.

Methods: This observational, cross-sectional study recruited 890 Chinese participants with bilateral high myopia, defined as ≤-6.00 diopters spherical power.

Progression and Longitudinal Biometric Changes in Highly Myopic Eyes.

Purpose: To examine 2-year progression rate and associated biometric changes in highly myopic eyes.

Methods: This is a longitudinal, observational cohort study that included 657 participants aged 7 to 70 years with bilateral high myopia (≤-6.00 diopters [D]) and followed for 2 years.

DIFFUSE CHORIORETINAL ATROPHY IN CHINESE HIGH MYOPIA: The ZOC-BHVI High Myopia Cohort Study.

Purpose: To explore the associations between diffuse chorioretinal atrophy (DCA) and age, sex, axial length, spherical equivalent, and best-corrected visual acuity (BCVA) among highly myopic eyes.

Methods: This study included right eyes of 857 bilaterally highly myopic individuals from the ZOC-BHVI Cohort Study. Participants underwent examinations, including BCVA, ocular biometry, autorefraction, and color fundus photography.

Progression of Myopic Maculopathy in Highly Myopic Chinese Eyes.

Purpose: To evaluate the 2-year changes in myopic maculopathy and its associations in highly myopic eyes.

Methods: This was a longitudinal, observational cohort study involving 657 Chinese participants with bilateral high myopia (≤ -6.00 diopters spherical power), who were followed for 2 years.

Displacement of a power-injectable PICC following computed tomography pulmonary angiogram.

Displacement of peripherally inserted central catheter (PICC) lines during contrast-enhanced computed tomography examinations is an underappreciated phenomenon. We report a case of iatrogenic PICC line displacement following the power injection of contrast during a computed tomography pulmonary angiogram. During the study, the PICC line was shown to move on 2 occasions, resulting in 2 nondiagnostic studies.

Drug-induced Myopia and Bilateral Angle Closure Secondary to Zolmitriptan.

Purpose: To describe a unique case of drug-induced transient myopia with angle-closure glaucoma in a patient being treated with zolmitriptan for migraines.

Methods: A 42-year-old woman who had been using increasing amounts of zolmitriptan over the previous 12 months presented with an acute myopic shift and raised intraocular pressures (IOP) with anterior chamber shallowing. Clinical examination findings at presentation and at follow-up visits were reviewed.
