FACTORS ASSOCIATED WITH DELAYED DIAGNOSIS IN PATIENTS WITH PRIMARY VITREORETINAL LYMPHOMA.

Purpose: To identify demographic and clinical factors associated with delayed diagnosis in patients with primary vitreoretinal lymphoma (VRL).

Methods: Retrospective, tertiary referral center-based cohort study of all patients at Mayo Clinic in Rochester, Minnesota, with a biopsy-proven diagnosis of VRL from January 1, 2000, to October 31, 2022.

Results: There were 87 patients included during the 22-year study period with 73 patients (83.

SUBRETINAL PHIALOPHORA ABSCESS IN CHRONIC GRANULOMATOUS DISEASE.

Purpose: To report a rare case of a subretinal Phialophora richardsiae abscess in a patient with chronic granulomatous disease.

Methods: A 21-year-old man with chronic granulomatous disease and a history of invasive pulmonary aspergillosis presented with progressive loss of vision and pain in his left eye. He was found to have a subretinal abscess with a macula involving serous retinal detachment.

GORE-TEX SUTURE-ASSOCIATED ENDOPHTHALMITIS IN A SCLERAL-SUTURED INTRAOCULAR LENS.

Purpose: To describe a unique case of Gore-Tex (Gore Medical, AZ) suture-associated delayed-onset endophthalmitis in a patient with a history of scleromalacia, pathologic myopia, multiple prior vitrectomies in the setting of a scleral-sutured intraocular lens (IOL).

Methods: A 69-year-old man complained of blurry vision and eye pain 21 months after implantation of a scleral-sutured IOL and was found to have an exposed Gore-Tex suture with scleromalacia, vision loss to hand motion, a hypopyon, and vitritis. He was diagnosed with culture-positive endophthalmitis.

Mask-induced Artifact Impacts Intraocular Pressure Measurement Using Goldmann Applanation Tonometry.

Purpose: The coronavirus (COVID-19) pandemic has impacted ophthalmology practices significantly. American Academy of Ophthalmology and Center for Disease Control guidelines suggest mandatory masking of patients and physicians during outpatient visits. We have recently become aware of a mask-induced phenomenon, whereby the intraocular pressure (IOP) as measured by Goldmann applanation tonometry (GAT) is artificially elevated due to mechanical interference from the mask.

Changes in Iridocorneal Angle and Anterior Chamber Structure in Eyes With Anatomically Narrow Angles: Laser Iridotomy Versus Pilocarpine.

Purpose: To compare the effects of laser iridotomy (LI) and pilocarpine on iridocorneal angle and anterior chamber structure in anatomically narrow angles (ANAs).

Materials And Methods: Temporal LI was performed 90 minutes after 2% pilocarpine administration in patients with occludable ANA. Swept-source optical coherence tomography B-scans of the anterior segment were obtained at baseline, 60 minutes after 2% pilocarpine administration, and 1 week after LI.

Relationship Between Optic Nerve Head Drusen Volume and Structural and Functional Optic Nerve Damage.

Purpose: The purpose of this study is to assess the relationships between optic nerve head drusen (ONHD) volume, retinal nerve fiber layer (RNFL) thickness and visual field (VF) loss.

Methods: Patients with ONHD and no other ocular or systemic conditions that can affect RNFL or VF were enrolled. Serial enhanced depth imaging (EDI) optical coherence tomography (OCT) B-scans of the optic nerve head (interval between scans, ~30 μm) were obtained from each participant.

Glaucoma Patient-Reported Concerns and Associated Factors.

Purpose: To assess the character and degree of concerns of glaucoma patients and identify demographic/clinical factors affecting the concerns.

Design: Prospective cross-sectional study.

Methods: A questionnaire that addressed patients' concerns was administered to consecutive glaucoma patients.

Iridocorneal Endothelial Syndrome Presenting With Large Diurnal Intraocular Pressure Fluctuation.

Purpose Of The Study: The purpose of the study was to report a case of iridocorneal endothelial syndrome with an initial presentation of a large diurnal fluctuation of intraocular pressure (IOP) which peaked early in the morning.

Methods: A 31-year-old white man had transient blurry vision oculus sinister (OS) upon awakening in the morning for the past 2 months. The blurry vision improved within 1 to 2 hours.

Effect of Pilocarpine Hydrochloride on the Schlemm Canal in Healthy Eyes and Eyes With Open-Angle Glaucoma.

Importance: The in vivo effect of pilocarpine hydrochloride on the Schlemm canal may help explain its pharmacologic mechanism of action and better indicate its clinical use.

Objective: To investigate the effect of pilocarpine on the structure of the Schlemm canal in vivo in healthy eyes and eyes with glaucoma.

Design, Setting, And Participants: In this case-control study, healthy individuals and patients with open-angle glaucoma were prospectively enrolled between September 1, 2013, and June 30, 2014, after a complete ophthalmologic examination at a tertiary glaucoma referral practice.
