PURPOSE To evaluate the outcome of transscleral fixation of closed loop haptic acrylic posterior chamber intraocular lens (PCIOL) in aphakia in nonvitrectomized eyes. MATERIALS AND METHODS Patients with postcataract surgery aphakia, trauma with posterior capsule injury, subluxated crystalline lens, and per operative complications where sulcus implantation(More)
Finding connected components in a graph is a well-known problem in a wide variety of application areas such as social network analysis, data mining, image processing, and etc. In this paper, we present an efficient and scalable approach in MapReduce to find all the connected components in a given graph. We compare our approach with the state-of-the-art on a(More)
Entity Resolution is the task of identifying which records in a database refer to the same entity. A standard machine learning pipeline for the entity resolution problem consists of three major components: blocking, pairwise linkage, and clustering. The blocking step groups records by shared properties to determine which pairs of records should be examined(More)
PURPOSE To describe the visual functions in amblyopia as determinants of response to treatment. METHODS Sixty-nine patients with unilateral and bilateral amblyopia (114 amblyopic eyes) 3 to 15 years old (mean age: 8.80 ± 2.9 years), 40 males (58%) and 29 females (42%), were included in this study. All patients were treated by conventional occlusion 6(More)
PURPOSE To evaluate a simplified method for correction of ocular deviation in patients of infantile and acquired basic esotropia. MATERIALS AND METHODS Thirty-six consecutive patients of infantile and acquired basic esotropia were selected for this study. Patients underwent unilateral recession-resection surgery as per the new norm gram. Patients(More)
Variational autoencoders (VAEs), that are built upon deep neural networks have emerged as popular generative models in computer vision. Most of the work towards improving variational autoencoders has focused mainly on making the approximations to the posterior flexible and accurate, leading to tremendous progress. However, there have been limited efforts to(More)
For big data practitioners, data integration/entity resolution/record linkage is one of the key challenges we face from day to day. Entity resolution/record linkage with high precision and recall on a large graph with billions of nodes, and hundreds of times more edges poses significant scalability challenges. Similarity based graph partition is still the(More)
AIMS To evaluate a new approach for recanalization (RC) of nasolacrimal duct obstruction in the treatment of the symptomatic nasolacrimal duct obstruction (NLDO). MATERIALS AND METHODS A prospective, interventional, comparative study in 302 eyes of 209 patients of symptomatic nontraumatic NLDO. Eyes with previous failed surgery were excluded. One hundred(More)
Dear Sir, We appreciate the interest shown in our work. Our response to the queries raised follows. I. For probing, after entering the puncta, the probe is initially directed medially until a hard stop is encountered. The probe is then slightly withdrawn and rotated upward 90°, in the same plane, and then angled to point 15° posteriorly.[1] Once the probe(More)
AIM The aim of this study was to establish a correlation between macular thickness on optical coherence tomography (OCT) and 2 visual functions (visual acuity and contrast sensitivity [CS]) in established cases of primary open angle glaucoma (POAG). MATERIALS AND METHODS A total of 50 consecutive patients of established POAG between 40 years and 70 years(More)
