Purpose: To determine whether people with age-related eye disease have lower cognitive scores than people with healthy vision.
Methods: A hospital-based cross-sectional study was performed in which 420 people aged 65 and older from the ophthalmology clinics at Maisonneuve-Rosemont Hospital (Montreal, Canada) were recruited who had age-related macular degeneration (AMD), Fuch's corneal dystrophy, or glaucoma. Patients with AMD and Fuchs had to have visual acuity in the better eye of worse than 20/40 while patients with glaucoma had to have visual field in their worse eye of at least -4 dB.
Background: The objective was to evaluate the eye care services offered to older residents living in long-term care facilities (LTCFs).
Methods: A questionnaire targeting residents aged ≥65 years was sent to all LTCFs in Quebec. Questions related to the institution's characteristics, demographic data related to residents, oculovisual health of residents and barriers to eye care, eye care services offered within and outside the institution, and degree of satisfaction regarding the eye care services offered to residents.

Purpose: To examine whether patients with age-related macular degeneration (AMD), glaucoma, or Fuchs corneal dystrophy report limiting their activity due to a fear of falling as compared with a control group of older adults with good vision.
Methods: We recruited 345 patients (93 with AMD, 57 with Fuchs, 98 with glaucoma, and 97 controls) from the ophthalmology clinics of Maisonneuve-Rosemont Hospital (Montreal, Canada) to participate in a cross-sectional study from September 2009 until July 2012. Control patients who had normal visual acuity and visual field were recruited from the same clinics.
Purpose: The purpose of this study is to examine whether patients with age-related eye diseases, like age-related macular degeneration (AMD), glaucoma, or Fuchs corneal dystrophy, are more likely to show signs of depression compared to a control group of older adults with good vision, and to determine whether reduced mobility mediates these relationships.
Methods: We recruited 315 eligible patients (81 with AMD, 55 with Fuchs, 91 with glaucoma, and 88 controls) from the ophthalmology clinics of a Montreal hospital from September 2009 until December 2011. Depressive symptoms were assessed using the Geriatric Depression Scale Short Form (GDS-15).
Age-related eye disease and mobility limitations in older adults.
Invest Ophthalmol Vis Sci
September 2011
Purpose: To examine the extent of mobility limitations in patients with age-related macular degeneration (AMD), glaucoma, or Fuchs' corneal dystrophy compared with that in a control group of older adults with good vision.
Methods: Two hundred seventy-two patients (68 with AMD, 49 with Fuchs' dystrophy, 82 with glaucoma, and 73 controls) from the ophthalmology clinics of Maisonneuve-Rosemont Hospital (Montreal, Canada) participated in a cross-sectional study from September 2009 until February 2011. Control patients who had normal visual acuity and visual fields were recruited from the same clinics.
Objective: To determine the utility of combining rim area to disc area asymmetry ratio (RADAAR) and Moorfields regression analysis (MRA) to detect primary open-angle glaucoma (POAG) using confocal scanning laser ophthalmoscopy (CSLO) (Heidelberg retina tomograph 3 (HRT3)) in high-risk populations.
Design: Cross-sectional study.
Participants: Subjects with high risk for developing POAG.
Purpose: According to our clinical observation, patients with quiescent herpes simplex virus (HSV) stromal keratitis often seem to present with signs of dry eye in the contralateral eye. Our goal was to compare dry eye signs and symptoms in both eyes of patients with quiescent HSV stromal keratitis with those of age- and sex-matched control subjects with healthy corneas.
Methods: A case-control study with 24 subjects per group.
Purpose: The goal of this study was to prospectively assess the deep lamellar endothelial keratoplasty (DLEK) wound anatomy and its evolution during the 12 months after surgery, using optical coherence tomography (OCT).
Methods: The eyes of 8 patients (1 eye per patient) who consecutively underwent DLEK for Fuchs dystrophy or pseudophakic bullous keratopathy were prospectively studied before and 1, 3, 6, and 12 months after surgery. The Stratus OCT apparatus (Carl Zeiss Meditec, Dublin, CA) was used to acquire central and radial scans perpendicular to the wound at 3-, 6-, 9-, and 12-o'clock positions.
Objective: To assess the cost-utility of posterior lamellar keratoplasty (PLK) techniques, including deep lamellar endothelial keratoplasty, Descemet stripping endothelial keratoplasty, and Descemet stripping automated endothelial keratoplasty, in the treatment of corneal endothelial diseases.
Design: Cost-utility analysis based on a Markov model.
Participants: Cohort of 100 patients waiting for corneal graft.
Objective: A cataract efficiency program was implemented in Montreal in 2003 to decrease surgery wait time. Our goal was to determine whether health, adverse events during wait time, and outcome of patients presenting for cataract surgery differed from 1999 to 2006 in Montreal.
Design: Prospective preoperative and postoperative observational study performed at 2 time points 6 years apart.
Objective: To estimate the annual incidence of endophthalmitis after cataract surgery from January 1, 1996, through December 31, 2005, in Quebec, Canada.
Methods: Deidentified data were obtained from an outpatient physician billing database (Quebec State Control for Health Insurance [RAMQ]) with regard to all cataract surgical procedures performed from January 1, 1996, through December 31, 2005, in Quebec. For this cohort, records of an International Classification of Diseases, Ninth Revision (ICD-9) code for endophthalmitis during the same years were requested from 2 sources: the RAMQ outpatient database and an inpatient hospital discharge database (Maintenance and Exploitation of Data for the Study of Hospitalized Patients [MED-ECHO]).
Objective: As provinces consider what an acceptable cataract surgery wait time should be, research is needed on the risk of adverse events, such as depression, while waiting for care. We sought to determine whether worse visual acuity is related to depressive symptoms in patients waiting to have cataract surgery.
Design: Cohort study.
Background: To improve the admissions process for the Université de Montréal (UdeM) ophthalmology residency program, the interview structure was modified to encompass the seven CanMEDS roles introduced by the Royal College of Physicians and Surgeons of Canada (RCPSC). These roles include an applicant's abilities as a communicator, collaborator, manager, health advocate, professional, scholar, and medical expert.
Methods: In this retrospective pilot study, the records of all applicants were reviewed by 8 members of the admissions committee, with a high intraclass correlation coefficient of 0.
The amniotic membrane, the most internal placental membrane, has various properties useful in ophthalmology. Collected on delivery by elective Caesarean section, the amnion is prepared under sterile conditions, and, usually, cryopreserved until its use as a biological bandage or as a substrate for epithelial growth in the management of various ocular surface conditions. Specifically, the amnion is used to : (1) limit formation of adhesive bands between eyelids and eyeball (symblepharon) or the progression of a fibrovascular outgrowth towards the cornea (pterygium) or to (2) facilitate the healing of corneal ulcers, bullous keratopathy, and corneal stem cell deficiency.

Recent Findings: Human fibrin glues may be used in place of cyanoacrylate tissue adhesives in the treatment of progressive corneal thinning and small perforations, potentially resulting in less corneal and conjunctival inflammatory reaction. Additional currently proposed uses of fibrin glues in ophthalmic surgery include minimizing sutures in recurrent pterygium surgery, forniceal reconstruction, amniotic membrane transplantation, and lamellar corneal grafting.
Purpose: To report one case of a bilateral ring-shaped opacity in the mid-peripheral corneal stroma of unknown origin.
Methods: Case report.
Results: The authors describe the clinical history and ocular examination of an asymptomatic 82-year-old woman with a bilateral ring-shaped opacity located in the corneal stroma.
Purpose: To assess visual functioning and other health-related quality of life outcomes after corneal grafting.
Design: A cohort study of corneal graft recipients observed for a minimum of 2 years after transplantation.
Methods: Repeated measurements were obtained by telephone interviews preoperatively and later at 1 and 2 years post-corneal transplantation in 217 patients with the following questionnaires: visual function index (VF-14), visual symptom score and global measures of trouble with vision, dissatisfaction with vision, ocular pain, and discomfort.
