Zone I retinopathy of prematurity (ROP) generally has a poorer prognosis than zone II ROP. The aim of this study was to evaluate the effect of early ROP treatment on the pathological findings on the retina at 6 months of age in relation to the extent of disorder. Preterm infants weighing less than 1500 g at birth were examined before 4 weeks of age. A total of 139 eyes in 93 infants were identi...

purpose : to evaluate the incidence and risk factors of severe visual impairment and retinopathy of prematurity (rop)-related blindness in a tertiary eye hospital in iran methods : in a cross-sectional study, clinical data of premature infants screened for rop in farabi eye hospital during 2003-2007 were reviewed. characteristics of advanced stages of rop (stage 4 or 5) were determined and comp...

At COLING80, we reported on an Interactive Translation System called ITS. We will discuss t h r ee p rob lems in the design of the first version of ITS: (1) human f ac to r s , (2) the "all or noth ing" syndrome, and (3) traditional centralized processing. We will also discuss a new vers ion of ITS, which is now being programmed. This new vers ion will hopeful ly o v e r c o m e these p rob lem...

The “richness” of properties that are indistinguishable from first-order properties is investigated. Indistinguishability is a concept of equivalence among properties of combinatorial structures that is appropriate in the context of testability. All formulas in a restricted class of second-order logic are shown to be indistinguishable from first-order formulas. Arbitrarily hard properties, incl...

AIMS To assess the outcome and complications of patients with advanced retinopathy of prematurity (ROP). METHODS All patients with eyes achieving stage 4 or 5 retinopathy of prematurity were reviewed. Twenty one eyes were diagnosed during ROP screening in maternity hospitals and 10 eyes were of infants transferred for treatment. RESULTS Thirty one eyes of 17 patients were included. Thirteen...

Regressed retinopathy of prematurity (ROP) and its sequelae were studied in children born prematurely (less than 1501 g birth weight and/or less than 33 weeks gestational age) in Stockholm county during 1976-81. Through various searches of the records at the different eye departments and other sources in Stockholm county we found that 134 out of a total of 528 premature babies (25.4%) had neede...

The purpose of this retrospective study is to evaluate the long-term ophthalmological outcome in children with retinopathy of prematurity (ROP) who were treated for threshold disease with indirect laser photocoagulation. 107 eyes of 56 patients with threshold ROP treated with indirect laser photocoagulation and 202 eyes of 101 control patients with spontaneously regressed ROP were included. Fix...

We present a case of retro-odontoid pseudotumor (ROP) without rheumatoid arthritis (RA) or atlantoaxial subluxation (AAS). A 76-year-old woman presented with paresthesia and weakness of both lower and upper extremities. She had no laboratory or physical findings of RA. Dynamic X-ray showed no AAS and magnetic resonance imaging (MRI) showed a retro-odontoid mass compressing the spinal cord. Tran...
