A 68-year-old male presented with a one-month history of progressive proptosis and vision loss in the left eye. Examination of the left eye showed visual acuity of NLP, marked relative proptosis of 10 mm, and complete external ophthalmoplegia. CT orbits showed an extensive left orbital lesion with proptosis.

However, results have been contradictory. Thus, we quantified the risk of maculopathy with PPS with a focus on risk with duration of use.

Design: Retrospective cohort study.
Methods: A retrospective review of consecutive treatment-naive patients receiving intravitreal anti-VEGF injections in a group practice was performed.
Purpose: The aim of this study was to evaluate the outcomes of cataract surgery in patients with chronic ocular graft-versus-host disease (GVHD).
Methods: A retrospective review was performed on 77 eyes of 42 patients with chronic ocular GVHD that underwent cataract surgery between January 2014 and February 2020 in a tertiary institution.
Results: Posterior subcapsular cataract was seen in 53 (68.
A consensus meeting was held in Toronto on February 9-10, 2020 to discuss ways to improve cornea donation and transplantation access in Canada. The meeting brought together eye and tissue bank representatives, health authority and hospital leadership, transplant ophthalmologists, organ donation organizations, transplant recipients, donor families and several national organizations. Through facilitated discussions in multidisciplinary, gender-balanced, and geographically balanced small groups, participants identified opportunities for improvement in the Canadian cornea donation and transplantation system.

Methods: A retrospective analysis of 68 eyes of 68 patients with Fuchs endothelial dystrophy who underwent DMEK triple between 2014 and 2018.
Results: The mean age of patients was 66.
Purpose: To investigate the incidence and outcomes of cystoid macular edema (CME) after Descemet membrane endothelial keratoplasty (DMEK) alone and DMEK combined with cataract surgery (DMEK triple).
Materials And Methods: A retrospective chart review was performed for patients who underwent DMEK and DMEK triple between January 2014 and March 2018 at two tertiary hospitals. Patients with minimum of 6 months of follow-up were included.
Objective: To characterize the total intraocular aqueous humour antibody profiles in cases receiving anti-vascular endothelial growth factor (anti-VEGF) for retinal vascular disease compared with controls without retinal pathology.
Design: Cross-sectional.
Participants: 93 aqueous humour samples: 22 eyes undergoing cataract surgery (controls) and 71 eyes receiving intravitreal injections (IVI) (cases) for macular edema or neovascularization.
Age-related macular degeneration (AMD) is a chronic degenerative disease of the retina. Recent reports have highlighted the potential role of mucosal surface microbes in the pathogenesis of AMD. In this case-control study, the composition of the nasal and oral microbiota in newly diagnosed neovascular age-related macular degeneration cases (6 male, 7 female) was compared to controls without retinal diseases (2 male, 3 female).

Charts of 121 patients (156 eyes) were reviewed who had at least 4 weeks of follow-up and both preoperative and postoperative measurements of best-corrected visual acuity or corneal cylinder. Outcome measures included: patient demographics, surgical indication, prior ocular history, best-corrected visual acuity (BCVA) changes, corneal and refractive astigmatism changes, recurrence of pathology, additional treatments required, and intraoperative and postoperative complications.
View Article and Find Full Text PDFObjective: To assess subjective and quantified metamorphopsia, as well as vision-related quality of life (QOL), in patients with age-related macular degeneration (AMD) to determine whether there is a correlation between quantified metamorphopsia and vision-related QOL in patients with AMD.
Methods: A cross-sectional study of patients with AMD. Patients who had a best-corrected visual acuity less than 20/200, vitreomacular adhesion, vitreomacular traction, epiretinal membrane, macular hole, macular edema by causes other than AMD, diabetic retinopathy, retinal detachment, previous retinal surgery, glaucoma, amblyopia, or strabismus were excluded.
Purpose: The purpose of this study was to develop a nomogram to predict postcut thickness of corneal grafts prepared at an eye bank for Descemet stripping automated endothelial keratoplasty (DSAEK).
Methods: Retrospective chart review was performed of DSAEK graft preparations by 3 experienced technicians from April 2012 to May 2017 at the Eye Bank of Canada-Ontario Division. Variables collected included the following: donor demographics, death-to-preservation time, death-to-processing time, precut tissue thickness, postcut tissue thickness, microkeratome head size, endothelial cell count, cut technician, and rate of perforation.
Purpose: To report a rare case of filamentary keratitis associated with stiff person syndrome.
Methods: Case report.
Results: A 26-year-old woman with several autoimmune conditions was referred because of filamentary keratitis.
Purpose: To assess the quality of the content of YouTube videos for cataract surgery patient education.
Setting: Hotel Dieu Hospital, Kingston, Ontario, Canada.
Design: Observational study.
Purpose: To highlight the potential risk of glaucoma drainage device erosion following ptosis surgery.
Methods: Case report.
Results: A 71-year-old man underwent uncomplicated superotemporal Ahmed glaucoma valve implantation in the left eye in 2008.
Purpose: To determine if the inflammatory composition of subretinal fluid in Vogt-Koyanagi-Harada (VKH) serous retinal detachments is predictive of photoreceptor injury, and to quantify photoreceptor recovery, following resolution of these detachments.
Methods: Optical density (OD) measurements of spectral-domain optical coherence tomography (SD-OCT) scans were used to derive the fibrinous index, a measure of the inflammatory composition of subretinal fluid. In order to assess photoreceptor status, photoreceptor outer segment (PROS) volume was measured from SD-OCT scans.
