Pupil size differences between female and male patients after cataract surgery.

2022

Purpose To evaluate the changes in pupil diameter in women and men after cataract surgery. The correlation of pupillary changes with the variables age and anterior chamber depth will be analyzed. Methods The values of 109 randomized eyes who underwent cataract surgery were obtained and divided into two groups, 71 women and 38 men. Pupil diameter was measured preoperatively and 3-months postoperatively using the pupillometer software of the Topolyzer Vario (Wavelight Laser Technologie AG). Anterior chamber depth was obtained with Pentacam® (Oculus). Differences in pupillary diameters were investigated and correlations with age and anterior chamber depth were analyzed.

Factors predicting normal visual acuity following anatomically successful macular hole surgery

2021

Purpose: To assess the incidence of normal vision following anatomically successful macular hole surgery and associated clinical variables. Methods: Multicentre, retrospective chart review. Preoperative, intraoperative and postoperative clinical data were extracted from electronic medical records from seven European vitreoretinal units. Inclusion criteria were as follows: eyes undergoing primary vitrectomy for idiopathic full-thickness macular hole from January 2015 to January 2018; postoperative macular hole closure confirmed by spectral domain optical coherence tomography (OCT); preoperative pseudophakia or phakic eyes receiving combined cataract surgery; one-year follow-up. The primary o…

Determinants of inappropriate hospitalization in cataract surgery in the south of Italy: a retrospective study

2017

Purpose To analyze the frequency of inappropriate hospitalization in cataract surgery and the type of related determinants. Methods A nested retrospective case–control study was carried out on 2708 consecutive cataract surgery patients operated between January 2013 and Decem- ber 2015. All cases with inappropriate hospitalization (day surgery or ordinary hospitalization) were com- pared with a control group of cases treated in an appropriate (day service) regimen. The predictive value for inappropriate admissions to the hospital was assessed using a logistic regression model. Significant variables from the univariate analysis were included in a multivariate model. Results Forty-five cases (…

Choroidal osteoma with choroidal excavation and associated neovascular membrane: An OCT-angiography study.

2017

Abstract Clinical case A case is presented of a unilateral choroidal osteoma with choroidal excavation and associated neovascular membrane that was studied using OCT-angiography. The OCT and OCT-angiography revealed an area of choroidal excavation and an active neovascular membrane. Three doses of aflibercept were administered to the patient, which stabilized the neovascularisation. Discussion OCT-angiography was used to analyze the morphology of the superficial vascular network of the osteoma, as well as to monitor the evolution of the neovascular membrane.

Brinzolamide/brimonidine fixed-dose combination bid as an adjunct to a prostaglandin analog for open-angle glaucoma/ocular hypertension.

2019

Purpose: To evaluate the additive intraocular pressure–lowering effect of twice-daily brinzolamide 1%/brimonidine 0.2% fixed-dose combination (BBFC) as an adjunct to a prostaglandin analog (PGA) in patients with open-angle glaucoma or ocular hypertension insufficiently controlled with PGA monotherapy. Methods: In this Phase 4, double-masked trial, patients aged ⩾18 years, with a mean intraocular pressure of ⩾19 and <32 mm Hg in at least one eye were randomized (1:1) to receive BBFC + PGA ( n = 96) or vehicle + PGA ( n = 92) for 6 weeks. The primary endpoint was the mean change in diurnal intraocular pressure from baseline (averaged over 09:00 and 11:00 h) at Week 6. Results: The mean diu…

Astigmatism in infancy and childhood.

2000

ABSTRACT Purpose: To evaluate the prevalence of astigmatism In infancy and childhood In a Spanish population. Methods: A total of 478 children with astigmatism from Valencia Province, Spain were examined. The patients, ranging in age from 2-1 2 years, were classified into groups according to age. Astigmatism error and axis orientation were determined using noncyclopeglc retlnoscopy over each eye. Results: The overall prevalence of astigmatism (5=1.00 diopter of cylinder) decreased In relation to increasing age from 44.3% to 5.2%. The prevalence of against-the-rule astigmatism decreased from 61.5% (at 2 years) to 33.4% (at 12 years), with-the-rule astigmatism increased In prevalence from 23.…

Clinical Outcome and Subjective Quality of Life after Photodynamic Therapy in Patients with Age-Related Macular Degeneration

2005

PURPOSE. Whereas the efficacy of photodynamic therapy (PDT) in preventing the progression of age-related macular degeneration (ARMD) is established, its effect on quality of life is under discussion. METHODS. All patientswho underwent PDT during 2000 and 2001 at the University Eye Hospital of Mainz were interviewed using a standardized 82-item questionnaire on quality of life and patient satisfaction in ophthalmologic patients. Information was assessed in terms of 82 questions; global scores ranging from 1.0 (optimum self-estimated quality of life) to 4.0 (worst) were derived. Cataract patients' scores were used to characterize the ARMD patients' subjective outcome; the latter were then rel…

Impact of lens material on objective refraction in eyes with trifocal diffractive intraocular lenses

2021

Purpose: Compare subjective (Rx) and objective (ObjRx) refractions outcomes with two autorefractors models and an aberrometer in eyes implanted with a hydrophobic trifocal IOL (FineVision POD F GF, Physiol, Liége, Belgium) and a hydrophilic one (FineVision POD F, Physiol, Liége, Belgium). Methods: Prospective comparative cohort study, with 100 subjects randomly assigned to either the POD F group (n = 50) or the POD F-GF group (n = 50). Postoperative eye examinations at 1-month visit included seven result sets, one for each assessment method: Rx, AR (automated refraction measured with the autorefractor KR8800), WF-P (Zernike-coefficients-based objective refraction, photopic pupil size), WF-M…

Relationship among Corneal Biomechanics, Refractive Error, and Axial Length

2014

Purpose To evaluate the relationship between different ocular and corneal biomechanical parameters in emmetropic and ametropic healthy white children. Methods This study included 293 eyes of 293 healthy Spanish children (135 boys and 158 girls), ranging in age from 6 to 17 years. Subjects were divided according to the refractive error: control (emmetropia, 99 children), myopia (100 children), and hyperopia (94 children) groups. In all cases, corneal hysteresis (CH) and corneal resistance factor (CRF) were evaluated with the Ocular Response Analyzer system. Axial length (AL) and mean corneal power were also measured by partial coherence interferometry (IOLMaster), and central corneal thickne…
