Purpose
To correlate the optical coherence tomography (OCT) based morphological patterns of diabetic macular edema (DME) and prognostic biomarkers with severity of anaemia in patients with diabetic kidney disease (DKD).
Patients and Methods
Single centre, observational cross sectional study of 42 eyes of 42 patients with DME and DKD. Eyes were div...
Purpose
Refractive error is a major cause of visual impairment in children and its early detection can prevent ocular morbidity such as amblyopia and strabismus. Brückner test is a comprehensive test which can be easily administered in children using a direct ophthalmoscope. We aimed to determine refractive error in children by analysis of the red...

We introduce Chákṣu–a retinal fundus image database for the evaluation of computer-assisted glaucoma prescreening techniques. The database contains 1345 color fundus images acquired using three brands of commercially available fundus cameras. Each image is provided with the outlines for the optic disc (OD) and optic cup (OC) using smooth closed con...
Purpose:
Glaucoma is an optic neuropathy where intraocular pressure is the only modifiable risk factor. Yoga is thought to adversely affect intra-ocular pressure (IOP) but we do not know if yogic breathing exercises can influence IOP. With this study, we aimed to determine the effect of specific nasal breathing techniques on intra-ocular pressure...
We report two cases with dense corneal arcus with abnormally low levels of serum high-density lipoproteins. One case with arcus senilis had a history of corneal clouding since youth but no systemic associations. The other case had an arcus juvenilis with anemia and hepatosplenomegaly but an absence of renal involvement. The genetic analysis of this...
We develop a fully automated method for the segmentation of optic disc in retinal fundus images using basis-spline-based active contour. The segmentation is achieved by performing scaling, translation, and rotation of the active contour, thereby giving rise to five free parameters. The energy of the active contour is defined by the local contrast a...
We report the occurrence of unilateral central retinal vein occlusion (CRVO) in a young yoga enthusiast who presented amidst the COVID-19 pandemic. Subtle signs of uveitis when systemically investigated revealed a multitude of causes, but ocular fluid polymerase chain reaction was positive for varicella zoster virus (VZV). The prompt initiation of...
AbstractAim: To assess the prevalence of severe visual impairment (SVI) and reasons for not accessing eye care services in a field practice area of a tertiary care hospital.Study design: Cross-sectional observational study.Materials and methods: Through a cross-sectional study using simple random sampling, a total of 1510, individuals above 18 year...
Objective: To evaluate the utility of a direct ophthalmoscope in detecting the type and magnitude of refractive error using a modified Brückner test.
Methods: In a prospective observational study, participants between the ages of 10 to 40 years underwent direct ophthalmoscopy by a single observer, using a modified interpretation of the Brückner tes...
Purpose
This study aimed to explore the role of smartphone imaging of the eye using two perspectives — anterior and temporal — in the detection of a shallow anterior chamber (AC). The AC depth (ACD) of an eye can be used as a surrogate marker for identification of eyes at risk of developing angle-closure disease.
Methods
A prospective observationa...

Study design: Cross-sectional observational study. Materials and methods: Through a cross-sectional study using simple random sampling, a total of 1510, individuals above 18 years of a...
Purpose of review:
Ocular manifestations of leprosy do occur despite advances in the areas of leprosy research. Understanding the nuances in the domain shall guide the clinician for effective patient-centered care.
Recent findings:
Despite the existence of microbiologic cure for leprosy, ocular manifestations of this disease do occur. Advances i...
We report a case of a young male from Udupi, Karnataka, presenting with features of bilateral non-granulomatous anterior uveitis with mild vitritis. There was a history of fever and myalgia a month before ocular features, which was partially treated. He also gave a history of being actively involved in the flood relief work in the district, before...
Purpose:
The purpose of the study was to study the association between diabetic retinopathy (DR) and periodontal disease (PD) in a South Indian cohort.
Methods:
This was a cross-sectional, observational, interdisciplinary hospital-based study wherein patients with diabetes mellitus visiting the ophthalmology department of a university teaching h...
Background: The proportion of diabetic patients having vision-threatening diabetic retinopathy and those needing to undergo vitrectomy was documented. Methods: A cross-sectional observational study was conducted at a tertiary care hospital in coastal Karnataka, South India. All patients with diabetes mellitus visiting the ophthalmology department i...
Purpose:
To compare the stereopsis in patients with various grades of cataract and bilateral pseudophakia.
Methods:
A cross-sectional observational study was conducted at a tertiary care center in South India from December 2016 to September 2018, wherein the stereoacuity of patients having bilateral senile cataract or bilateral pseudophakia, was...
Purpose:
To compare the posterior capsular opacification (PCO) after implantation of three types of hydrophobic square edge intraocular lenses (IOLs).
Methods:
A single-center, hospital-based, cross-sectional, observational study was conducted wherein patients with senile cataract who had undergone phacoemulsification by a single surgeon, with t...
Purpose
To evaluate the effect of two herbal mouthwashes containing aloe vera and tea tree oil, on the oral health of school children.
Methods
A double-blinded, placebo-controlled prospective interventional study was conducted in school children aged 8–14 years. The study participants were divided into four groups depending upon the mouthwash used...
We present a novel and fully automated fundus image processing technique for glaucoma prescreening based on the rim-to-disc ratio (RDR). The technique accurately segments the optic disc and optic cup and then computes the RDR based on which it is possible to differentiate a normal fundus from a glaucomatous one. The technique performs a further cat...

We present a rare case of corneal ulcer caused by a species of a coelomycetes fungus, Chaetomium strumarium. This fungal genus is a rare causative agent of keratomycosis, with only a handful of cases reported. The clinical presentation, investigative techniques, and preliminary management of our patient are reported. The cases reported in global li...
A 60-year-old woman with no premorbidities presented with symptoms of sudden painless vision loss in the left eye (LE). Best-corrected visual acuity in the LE was counting fingers close to face. A relative afferent pupillary defect was observed in the LE. Ocular fundus examination of LE was suggestive of central retinal artery occlusion. Systemic e...
Ocular parasitology is the study of parasites that infect humans and result in ocular complications. Complications occur either due to mechanical, immunologic, or allergic reactions [1]. Because of protean manifestations and lack of clinical suspicion, the diagnosis is often missed. Prior to making a final diagnosis, ophthalmologists have to get di...

We report an atypical presentation of Toxoplasma retinochoroiditis with associated scleritis in a young and immunocompetent patient. The diagnosis was done on the basis of Polymerase chain reaction of vitreous sample, and the clinical response to specific treatment. This case highlights the unusual presentation of ocular toxoplasmosis as scleritis.
