Aim: To determine risk factors for lens opacities and age related cataract in an older rural population of southern India. Methods: A cross sectional population based study of 5150 people aged 40 years and above from 50 clusters from three districts in southern India. The lens was graded and classified after dilation using LOCS III system at the slit lamp for cataract. Definite cataract was def...

Video feedback provides a wealth of information about surgical procedures and is the main sensory cue for surgeons. Scene understanding crucial to computer assisted interventions (CAI) post-operative analysis procedure. A fundamental building block such capabilities identification localization instruments anatomical structures through semantic segmentation. Deep learning has advanced segmentati...

Congenital cataracts are one of the leading causes of visual impairment and blindness in children, and genetic factors play an important role in their development. This study aimed to identify the genetic defects associated with autosomal dominant congenital progressive punctate cataracts in a Chinese family and to explore the potential pathogenesis. Detailed family history and clinical data we...

PURPOSE The purpose of this study was to investigate the thiol repair systems of thioltransferase (TTase) and thioredoxin (Trx) and oxidation-damaged proteins in human cataractous lenses. METHODS Cataractous lenses in humans (57-85 years of age) were classified into cortical, nuclear, mixed, mature, and hypermature cataract types by using a lens opacity classification system, and were obtaine...

Intervention: households were allocated to PEP (n = 138 households with 410 HHCs) or expectant treatment (n = 139 households with 402 HHCs). All index patients and HHCs developing illness in the expectant treatment group received oseltamivir treatment (adults and adolescents 75 mg capsules; and children 30–60 mg suspension twice/day) for 5 days. HHCs in the PEP group received the same dosage as...

Higher visual functions were investigated in patients treated for bilateral congenital cataracts in two experiments. Participants were asked to detect either real or illusory contours (Kanizsa squares in Experiment 1 or one of four different Kanizsa contours in Experiment 2) among distractor items. Compared to normally sighted participants matched for age, gender and education, cataract patient...

ABSTRACT: Objective was to evaluate the accuracy of elastography in differentiation between normal and cataract lenses One hundred forty-five eyes 98 dogs were divided into groups according stage. Forty-twoeyes submitted phacoemulsification. Biometric parameters, echogenicity echotexture patterns anterior, posterior vitreous chambers, lens retina-choroid-sclera complexes evaluated by ocular ult...

Subject Peter Doyle (PD) had congenital bilateral cataracts removed at the age of 43. Pre-operatively PD's visual acuity was 20/80, with a resolution limit around 15 cpd, and he experienced monocular diplopia with high contrast stimuli. Post-operatively PD's visual acuity improved to approximately 20/40, with a resolution limit around 25 cpd. Using a variety of pre- and post-operative tests we ...

PURPOSE Dense congenital unilateral cataracts may compromise visual development through visual deprivation and biased interocular competition, whereas dense congenital bilateral cataracts compromise visual development primarily through visual deprivation alone. Differences in sensory deficits between the two patient groups with these disorders may reflect the specific effects of unequal competi...

Abstract To report novel ocular findings in unique Marinesco-Sjögren syndrome (early-onset cataracts, cerebellar ataxia, and a progressive myopathy), review literature, discuss causes of vision decrease this rare entity. A 3-year-old girl diagnosed with underwent uneventful cataract surgery both eyes within 1 week her 2nd birthday. This was exactly similar to sister other two related family mem...
