Purpose: The main objective of this study was to examine the pupillary response in patients with Marfan syndrome (MFS) and secondarily to determine whether changes in the pupillary response are associated with the increased disability glare previously shown in the same patient population.
Methods: This study included 60 eyes of 34 patients with MFS diagnosed in accordance with the Ghent-2 criteria and 81 eyes of 44 controls. Pupillary response was measured with a pupillograph and disability glare with a straylight meter.
Purpose: The aim of the present study was to investigate photophobia and disability glare in adult patients with Marfan syndrome (MFS).
Methods: In this case-control study, 44 patients with MFS (87 eyes) were compared to 44 controls (88 eyes), who were matched for age and sex. The subjects were asked to grade their photophobia and glare using 10-cm visual analogue scales (VAS), which were marked with 'never' at zero and 'always' at 10 -cm.
Aim: To investigate the long-term risk of suture breakage after implantation of a modified capsular tension ring (MCTR) fixated to the sclera with polypropylene 10-0 suture.
Methods: Retrospective case series of operations for subluxated phakic lenses in 2007-2015 with implantation of an MCTR secured with a 10-0 polypropylene suture as part of an intraocular lens (IOL)-capsular bag complex.
Results: We identified 132 eyes (92 patients) operated on with an MCTR.
The age-dependent penetrance of organ manifestations in Marfan syndrome (MFS) is not known. The aims of this follow-up study were to explore how clinical features change over a 10-year period in the same Norwegian MFS cohort. In 2003-2004, we investigated 105 adults for all manifestations in the 1996 Ghent nosology.

Purpose: The purpose of this study was to determine whether patients' distance vision is optimally corrected with spectacles 6 to 7 years after cataract surgery and whether patients with glaucoma who regularly visit an ophthalmologist have more correct power in their spectacles.
Purpose: To compare the clinical outcome 2 years after corneal collagen cross-linking (CXL) with conventional and accelerated ultraviolet A (UVA) irradiation using riboflavin with hydroxypropyl methylcellulose.
Methods: Prospective randomized controlled study. Forty patients with keratoconus (40 eyes) were randomized to either CXL using conventional 3 mW/cm UVA irradiation for 30 minutes (CXL30 group) or accelerated 9 mW/cm UVA irradiation for 10 minutes (CXL10 group).
Purpose: To compare the effect of corneal collagen cross-linking (CXL) on progressive keratoconus using 0.1% riboflavin with either dextran or methylcellulose as the main supplement.
Methods: In a comparative case series, CXL was performed in 40 patients (40 eyes) using a riboflavin solution containing either dextran (dextran-riboflavin; n = 20) or methylcellulose (methylcellulose-riboflavin; n = 20).
Importance: Long-term follow-up of Marfan syndrome (MFS) patients.
Background: Investigate changes in ocular features in MFS patients fulfilling the Ghent-2 criteria following a period of 10 years.
Design: Repeated cross-sectional study with two observations.
Purpose: To evaluate corneal collagen crosslinking (CXL) with conventional and accelerated ultraviolet-A (UVA) irradiation using riboflavin with methylcellulose.
Setting: Department of Ophthalmology, Oslo University Hospital, Oslo, Norway.
Design: Prospective randomized case series.

Purpose: To assess the interrelationship of different methods of measuring the demarcation line depth after corneal collagen crosslinking (CXL).
Setting: University eye clinic, Oslo, Norway.
Design: Prospective case series.
Purpose: To compare glaucoma development and intraocular pressure (IOP) in the longer term following phacoemulsification cataract surgery in eyes with and without pseudoexfoliation syndrome (PEX).
Methods: Fifty-one patients with PEX were compared with 102 age- and gender-matched controls without PEX. Patients were re-examined a mean of 76 (SD 5.
Purpose: To investigate whether the introduction of corneal collagen cross-linking (CXL) influences the frequency of keratoplasties in patients with keratoconus.
Methods: Data were obtained from a cohort of patients from our corneal transplant registry. Two different periods were compared, 2005 to 2006 (period 1) and 2013 to 2014 (period 2).
Purpose: To assess long-term positioning of posterior chamber intraocular lenses within the capsular bag in eyes with pseudoexfoliation syndrome.
Methods: The study includes 44 patients with pseudoexfoliation syndrome and 85 age-matched controls, who underwent cataract surgery in 2001 and 2002 at the Eye Department, Oslo University Hospital. In 2008, all patients were re-examined.
Purpose: To assess preoperative features, frequency, surgical approaches and outcomes of late in-the-bag dislocation of posterior chamber intraocular lenses (IOLs) in eyes with pseudoexfoliation syndrome.
Methods: Seventy-seven patients (81 eyes) were enrolled. Inclusion criteria were patients with pre-existing pseudoexfoliation syndrome who underwent surgery for late in-the-bag IOL dislocation between March 2004 and April 2010.
Purpose: The main aim of the study was to assess whether omitting prophylactic postoperative topical antibiotics (chloramphenicol) influenced the risk of developing endophthalmitis after cataract surgery.
Methods: We conducted a retrospective study including all patients who had cataract surgery at our outpatient cataract unit between 2004 and 2011. Postoperative topical antibiotics (chloramphenicol) were omitted from 2007 onwards, as was the first postoperative day review.
