BACKGROUND: Although artificial intelligence performs promisingly in medicine, few automatic disease diagnosis platforms can clearly explain why a specific medical decision is made. OBJECTIVE: We aimed to devise and develop an interpretable and expandable diagnosis framework for automatically diagnosing multiple ocular diseases and providing treatment recommendations for the particular illness of a specific patient. METHODS: As the diagnosis of ocular diseases highly depends on observing medical images, we chose ophthalmic images as research material...

OBJECTIVES: Because vitrectomy-associated postoperative ocular surface changes are not well known, we evaluated such changes before and after vitrectomy in eyes with posterior segment diseases and investigated their associations with patients' characteristics and surgical procedures. METHODS: Thirty-five eyes of 32 consecutive patients (16 women; average age 66.6±11.1 years) were included in this prospective, noncomparative case series from tertiary care university hospital...

PURPOSE: To evaluate the clinical outcomes of preloaded large-diameter ultra-thin grafts for Descemet stripping automated endothelial keratoplasty (UT-DSAEK) after cross-country shipment. METHODS: A laboratory study in an eye bank and a clinical cohort study in an academic tertiary care center were performed. UT-DSAEK (9.5 mm diameter) grafts (n = 7) were prepared, loaded into a commercial device (iGlide; Eurobio, Les Ulis, France), preserved for 4 days at room temperature in transport medium, and analyzed...

Background: Cataract, glaucoma, and conjunctivitis are common causes of ocular morbidity in Nigeria. A major obstacle in reducing the burden of ocular morbidity in rural areas is access to eye care services. Up to 80% of the population in developing countries use traditional medications for their primary healthcare needs because they are accessible, available, and affordable. The aim of this study is to evaluate the content and cost of commercialized traditional medications used in the treatment of common eye conditions in Nigeria...

Purpose: To compare the outcomes of amniotic membrane transplantation (AMT) vs cultivated limbal stem cell transplantation (LSCT) in eyes with partial limbal stem cell deficiency (LSCD) following chemical burns. Methods: Eyes with unilateral partial LSCD (#180° involvement) were randomized in two groups to undergo either pannus resection combined with AMT or pannus resection combined with LSCT in a tertiary eye care hospital. Primary outcome measures were time to corneal epithelialization and absence of conjunctivalization of the cornea...

PURPOSE: To assess the incidence of lacrimal drainage disorders across a tertiary eye care network in India. METHODS: A 5-year retrospective review of all the patients who were diagnosed with lacrimal drainage disorders across the tertiary care network of L.V. Prasad Eye Institute was performed from January 2013 to December 2017.

Patients often detect melanoma themselves; therefore, regular skin self-examinations (SSEs) play an important role in the early detection and prompt treatment of melanoma. Mobile teledermoscopy is a technology that may facilitate consumer SSEs and rapid communication with a dermatologist. This paper describes the planned randomised controlled trial of an intervention to determine whether mobile technologies can help improve the precision of SSE in consumers. A randomised controlled trial will be conducted to evaluate mobile teledermoscopy-enhanced SSE versus naked-eye SSE...

PURPOSE: To determine the usefulness of preoperative OCT examination to detect asymptomatic macular abnormalities in patients scheduled for cataract surgery METHODS: Design: Prospective, interventional case series Setting: Iladevi Cataract and Visakha Eye Center, Ahmedabad, IndiaStudy Population: Patients undergoing cataract surgery and intraocular lens(IOL) implantation for senile cataracts. Preoperatively no retinal/macular pathology was identified on clinical evaluation. INTERVENTION: All eyes underwent Macular 5-Line Raster evaluation using Spectral Domain OCT before and after cataract surgery(monthly for 3 months)...

PURPOSE: To investigate a new algorithm to perform an automated non-cycloplegic refraction in adults. METHODS: Fifty healthy subjects were measured twice (test-retest) with the new automated subjective refraction method and with the conventional clinician subjective refraction procedure. Objective refraction was also measured with the Grand Seiko WAM-5500 autorefractor. The new automated method was inspired on the root finding bisection algorithm and on the Euclidean distances in the power vector domain...

OBJECTIVE: Diabetic retinopathy remains the leading cause of blindness among working-age U.S. adults largely due to low screening rates. Rural populations face particularly greater challenges to screening because they are older, poorer, less insured, and less likely to receive guideline-concordant care than those in urban areas. Current patient education efforts may not fully address multiple barriers to screening faced by rural patients. We sought to characterize contextual factors affecting rural patient adherence with diabetic eye screening guidelines...

BACKGROUND: We aimed to construct a prediction tool for postoperative oxygen therapy and determine predictors of duration of use among children undergoing non-cardiac surgery. METHODS: Data from this case-control study was obtained from a database of 9820 children aged < 15 years who underwent general anesthesia between January 2010 and December 2013 at a tertiary care hospital in southern Thailand. The primary outcomes were the use and duration (hours) of postoperative oxygen therapy (cases)...

Artificial intelligence (AI) based on deep learning (DL) has sparked tremendous global interest in recent years. DL has been widely adopted in image recognition, speech recognition and natural language processing, but is only beginning to impact on healthcare. In ophthalmology, DL has been applied to fundus photographs, optical coherence tomography and visual fields, achieving robust classification performance in the detection of diabetic retinopathy and retinopathy of prematurity, the glaucoma-like disc, macular oedema and age-related macular degeneration...

IMPORTANCE: Optical coherence tomography software classifies abnormality of macular ganglion cell-inner plexiform layer thickness and macular retinal nerve fibre layer thickness based on adult series. BACKGROUND: We assessed the impact of using paediatric reference macular ganglion cell complex values instead of adult reference values. DESIGN: Cross-sectional study. Primary and tertiary health-care setting. PARTICIPANTS: Out of 140 healthy participants aged 5 to 18 years, 90% were eligible...

OBJECTIVE: This study was conducted to analyze data from emergency ophthalmology referrals after hours from different hospitals to identify the most common pathologies and compare accuracy of diagnoses. Additionally, examination findings, including visual acuity (VA), intraocular pressure (IOP), and pupils from referring service and ophthalmic examination, were compared to assess agreement. DESIGN: This was a prospective study that reviewed information collected from referring services to the emergency on-call ophthalmology service and compared it with ophthalmic examination between February 2017 and July 2017...
