Comparative analysis of OCT-defined parapapillary beta and gamma zones between primary open angle glaucoma and primary angle closure glaucoma.

Sci Rep 2022 Jun 30;12(1):11070. Epub 2022 Jun 30.

Department of Ophthalmology & Visual Science, Eye & ENT Hospital, Shanghai Medical College, Fudan University, 83 Fenyang Road, Shanghai, 200031, China.

The ophthalmoscopic beta zone of parapapillary atrophy has recently been proposed to divide into a gamma zone and a (new) beta zone based on OCT imaging. The present study was undertaken to compare the microstructural characteristics of parapapillary gamma and beta zones and their influencing factors between primary open angle glaucoma (POAG) and primary angle closure glaucoma (PACG). Seventy-three PACG patients that had no evidence of an acute attack and 78 POAG patients were enrolled. Read More

TOPIRAMATE-INDUCED BILATERAL ANGLE-CLOSURE GLAUCOMA. A CASE REPORT.

Cesk Slov Oftalmol 2022 ;78(3):138-142

Introduction: Topamax (topiramate) is a drug used in the treatment of epilepsy or migraine. Its use may rarely be associated with the occurrence of secondary angle-closure glaucoma due to supraciliary effusion. Although the ocular finding resembles primary angle-closure glaucoma, bilateral infliction should always raise the suspicion that it is drug-induced glaucoma. Read More

Very High-Frequency Ultrasonography Signs in Bilateral Acute Choroidal Effusion Associated with Systemic Sulphonamide Medications: 2 Cases.

Case Rep Ophthalmol 2022 Jan-Apr;13(1):64-69. Epub 2022 Feb 14.

Unidad de Retina Quirúrgica y Tumores Intraoculares del Adulto (URQTIA), Área Sanitaria de Santiago de Compostela y Barbanza, Complejo Hospitalario Universitario de Santiago de Compostela, Servizo Galego de Saúde (SERGAS), A Coruña, Spain.

Sulphonamides are commonly used in medicine for several purposes; however, they can lead to significant adverse effects, including idiosyncratic reactions and choroidal detachment corresponding to a forward rotation of the iris-lens diaphragm; this could also evolve into acute transient myopia with possible acute angle closure glaucoma. The risk of such reactions to sulphonamides is approximately 3%. In our communication, we have reported on 2 cases involving patients who suffered choroidal detachments after starting sulphonamide treatments and who were diagnosed with the help of ultrasound biomicroscopy.

Department of Ophthalmology, First Hospital of China Medical University, Shenyang, China.

Vogt-Koyanagi-Harada disease (VKH) is a rare multisystemic inflammatory autoimmune disorder. Glaucoma secondary to VKH frequently occurs during the recurrent phase of anterior uveitis; however, acute angle-closure glaucoma (ACG) secondary to both VKH and human immunodeficiency virus (HIV) infection has rarely been reported. We describe a case of secondary acute ACG involving VKH, characterized by sudden vision loss, moderately elevated intraocular pressure (IOP), shallow anterior chamber, and fully or partially closed angle, in an HIV-infected patient.
