Recent advances in the diagnosis and treatment of ectatic corneal disease have mandated a more modern staging system. The new Belin ABCD keratoconus system incorporates anterior posterior curvature centered on thinnest point cornea, pachymetry values distance visual acuity grades from 0-4. By including thickness measurements based point, as opposed to apical, better reflects anatomical changes seen other diseases.
Objective To assess the accuracy of probabilistic deep learning models to discriminate normal eyes and with glaucoma from fundus photographs visual fields. Design Algorithm development for discriminating using data multicenter, cross-sectional, case-control study. Subjects participants Fundus photograph field 1,655 929 subjects develop test an independent group 196 98 patients validate models. Main outcome measures Accuracy area under receiver-operating characteristic curve (AUC). Methods...
Purpose: To study the prevalence, determine magnitude, and cause of amblyopia among children aged 6 months to 16 years in Kamrup district, Assam, India. Methods: Among a total 39,651 between age, door-to-door screening was conducted by trained workers. For above 5 age who failed read 6/9 line, camps were nearby schools. Children below directly referred tertiary eye care institute. After visual acuity assessment at institute, cycloplegic refraction complete ophthalmic examination done rule...
PURPOSE: To develop an artificial intelligence (AI) model to effectively assess local versus global progression of keratoconus using multiple tomographic parameters. METHODS: This was a retrospective review medical records patients diagnosed as having keratoconus. A total 1,884 Pentacam (Oculus Optikgeräte GmbH) scans 366 eyes (296 patients) were analyzed. Based on increase in maximum anterior curvature (Kmax), the classified actual “progression” and “no progression.” The corresponding...
Automatic identification of mitotic type staining patterns in microscopy images is an important and challenging task, computer-aided diagnosis (CAD) autoimmune diseases. Such are manifested on a HEp-2 based cell substrate captured via Indirect immunoflourescence (IIF) imaging technique. The present study proposes deep metric learning methodology, order to identify the which rather rare, among several other interphase majority. Hence, problem framed as v/s non-mitotic/interphase pattern...
Aim: To report the clinical profile of non-strabismic binocular vision anomalies (NSBVA) in patients with asthenopia North-East India. Materials and methods: A hospital based study was conducted on 131 from age group 10-40 years attending therapy clinic. Patients were divided into groups 10-20 years, 21-30 31-40 years. detailed orthoptic evaluation carried out including sensory motor testing a diagnosis made comparing various parameters particular patients. Results: Of patients, 81 female 50...
Aim: To form a profile of brain tumors having ocular manifestations presenting to tertiary eye care institute. Materials and Methods: The medical records patients diagnosed with primary between January 2012 December 2017 were reviewed. Patients underwent detailed examination neuroimaging confirm the diagnosis. Results: Out 17 patients, 11 (65%) female 6 (35%) male. mean age was found be 43.17 ± 11.04 years majority belonged group 21—40 (47.06%). most common symptom diminution vision (100%),...
Coronavirus pandemic has strained the healthcare system with mortality and morbidity. A number of elective surgeries have come to standstill due lockdown movement restrictions. Refractive surgery being a purely procedure quite fresh subset ophthalmology, there is lack unanimity as what precautions should be followed resume practice same. This article attempts highlight simple guidelines in accordance an expert panel, which can by all those involved directly or indirectly refractive services...
Morgagnian cataract (MC), named after the Italian anatomist anatomist, Giovanni B. Morgagni, is a in which there liquefaction of cortex and sinking dense nucleus capsular bag.[12] In some cases, liquified cortical matter gets completely resorbed leaving behind just transparent lens capsule superiorly bag inferiorly. This may be confused with inferiorly subluxated cataractous due to superior zonular dialysis. A 65-year-old female presented diminution vision right eye for 6 months. Slit lamp...
Deep archetypal analysis (DAA) has recently been proposed as an unsupervised approach for discovering latent structures in data. However, while a few approaches have used classical (AA), DAA not incorporated medical image yet. The purpose of this study is to develop precognition framework identify preclinical signs glaucomatous vision loss using convex representations derived from DAA. We first AA structure and novel recognize hidden patterns visual functional loss, then project field data...
Thelazia callipaeda or the oriental eye worm infects a wide variety of hosts including dogs, cats, foxes, rabbits, and humans through Drosophila flies. We report here case 42-year-old female who presented with pain, redness, cystic swelling in right lacrimal sac area for 8 months. Ocular examination was within normal limits. Excision biopsy cyst revealed live worm. In humans, is usually found conjunctival sac, canaliculi, leading to disease which can be subclinical symptomatic. Thus, we rare...
We propose and analyze a novel framework for classification of HEp-2 cell images. It is based upon two important aspects. First, we to utilize the expert knowledge about visual characteristics classes formulate class-specific image features. Secondly, realizing that problem involves small number classes, treat task as hierarchical verification subtasks. Thus, overall posed each class, using its The current study reports results Nuclear Membrane Golgi classes. demonstrate our yields high rate...
The paper proposes a class-specific feature assisted automatic classification approach of microscopic HEp-2 cell images. Unlike traditional methods our method highlights two important aspects: (1) the visual characteristics classes to formulate image features and (2) task is treated as hierarchical verification sub-tasks. Thus, overall problem modeled each class, using its features. We have demonstrated that proposed yields high rate utilizing simple efficient with only (20%) data for...

The persistent pupillary membrane is the remnant of tunica vasculosa lentis, primary blood supply lens during embryogenesis, most commonly seen ocular “congenital anomaly”.[1] It classified as follows: Type 1, attached to iris only; 2, iridolenticular adhesions; and 3, cornea. One variety 2 epicapsular stars, a rare entity, which presents multiple, star-shaped, brown-colored opacities over anterior capsule, also known chicken tracks.[23] A 22-year-old male presented with dry eye. His unaided...
The sentiment of the data contained in a text can be determined by analysis. This good, negative, or neutral. When carrying out this research, one may choose to employ either uni-model multi-model technique. In method, both training and analysis are performed using just single model. application strategy is uncomplicated uncomplicated, but it might not able make sense complicated different facts, which would lead wrong findings. Instead, technique utilizes number models, each designed...
