AIMS Visual outcome of 66 eyes in 37 patients who had undergone treatment with either cryotherapy or diode laser for threshold retinopathy of prematurity was assessed. METHODS 17 patients, representing 30 eyes treated with cryotherapy, were examined at between 56 and 98 months corrected age (median 68 months). 20 patients representing 36 eyes treated with diode laser, were examined at between...

BACKGROUND With advances in the delivery of excimer laser energy to the cornea, spherocylindrical ablations are now possible. The refractive and visual outcome of eyes undergoing photoastigmatic refractive keratectomy with a minimum of 12 months follow-up are presented. METHODS A retrospective analysis of 160 consecutive eyes that underwent photoastigmatic refractive keratectomy using the Nid...

PURPOSE To report the prevalence of blindness and visual impairment and the contribution of uncorrected refractive error to visual loss, in a population-based sample of Mexican Americans aged 40 and older. METHODS Proyecto VER is a population-based study of blindness and visual impairment in Mexican Americans in Arizona. Block groups in Tucson and Nogales were randomly selected with probabili...

OBJECTIVE To compare the effects on visual acuity of laser treatment (LT), photodynamic therapy (PDT) with verteporfin, and intravitreal bevacizumab treatment in patients with juxtafoveal choroidal neovascularization secondary to pathologic myopia. METHODS This prospective randomized clinical investigation enrolled 54 patients, who were divided into 3 groups receiving PDT, LT, or intravitreal...

AIM To evaluate the use of accelerated corneal collagen cross-linking in the management of mild and moderate progressive keratoconus in comparison with conventional cross-linking. PATIENTS AND METHODS Prospective randomized interventional case-control clinical trial. A total 25 eyes of 18 patients were randomly divided into two groups: group A included 14 eyes that received accelerated collag...

PURPOSE To present a format for reporting outcomes of aberrometer-guided refractive procedures. SETTING SurgiVision Consultants, Inc., Scottsdale, Arizona, and Food and Drug Administration, Center for Devices and Radiological Health, Rockland, Maryland, USA. METHODS Reports of standard refractive and visual outcomes (uncorrected visual acuity, manifest refractive spherical equivalent, best ...

All RDs are accompanied by some loss of visual function but this will vary depending upon the type of detachment, its size, and retinal location, making it difficult to ascribe one set of symptoms to the condition (Box 71.3). Diagnosing RD is complex with many qualifications. Abnormal vision is the only reliable symptom of RD. But the types of abnormal vision are large and varied: light flashes...

BACKGROUND The purpose of this study was to evaluate the effect of use of contact lenses to improve visual outcome after repair of traumatic corneal wounds. METHODS Two groups of patients (n=30 each) with traumatic full thickness corneal wounds were entered into this study. All cases were caused by sharp objects such as a knife or piece of glass that produced a corneal full thickness wound wi...

PURPOSE To report the impact of transient, self-resolving, untreated "macular edema" detected on spectral domain optical coherence tomography in Asian Indian premature infants with retinopathy of prematurity (ROP) on visual acuity (VA) and refraction at 1-year of corrected age. MATERIALS AND METHODS Visual acuity and refraction of 11 infants with bilateral macular edema (Group A) was compared...
