Background: Eye care organizations and professionals worldwide are increasingly focusing on bridging the gap between population health and medical practice. Recent advances in genomics and anthropology have revealed that most Indian groups trace their ancestry to a blend of 2 genetically distinct populations: Ancestral North Indians, who share genetic affinities with Central Asians, Middle Easterners, Caucasians, and Europeans; and Ancestral South Indians, genetically distinct from groups outside the Indian subcontinent. Studies conducted among North Indian populations can therefore offer insights that are potentially applicable to these diverse global populations, underscoring significant implications for global health.

- This study explores how adaptive optics-transscleral flood illumination (AO-TFI) imaging can provide detailed insights into retinal pigment epithelium (RPE) changes in cases of central serous chorioretinopathy (CSCR) compared to standard clinical imaging.
- Researchers analyzed 125 AO-TFI images from both affected and healthy eyes, finding significant changes in RPE contrast and patterns during different stages of CSCR.
- The findings indicate that AO-TFI not only gives a clearer picture of outer retinal abnormalities but also reveals previously undetectable RPE issues, underscoring the need for further research to assess the clinical implications of these findings in understanding CSCR progression.
Article Synopsis
- * Key findings showed that the overall prevalence of any VI was 12.0%, with cataracts being the leading cause, accounting for a significant majority (78.08%) of cases. The prevalence of blindness was relatively low at 1.3%.
- * Age was a major risk factor, with a notable increase in the odds of blindness for those over 70 years, highlighting the need for improved eye care services to address this public health issue in the region.
Purpose: To ascertain the anatomic factors that help achieve non-surgical sealing in full thickness macular hole (FTMH).
Methods: Retrospective collaborative study of FTMH that closed without surgical intervention.
Results: A total of 78 patients (mean age 57.
Retinopathy Secondary to Uncomplicated Plasmodium vivax Malaria.
Ophthalmic Surg Lasers Imaging Retina
January 2021
To report a case of bilateral malarial retinopathy secondary to uncomplicated Plasmodium vivax malaria. A 45-year-old male patient presented with sudden onset of diminution of vision both eyes and was treated for P. vivax malaria 1 week before the ocular symptoms.

Methods: Patients with diagnosis of CSCR, either acute or chronic, were included in this multicentric, retrospective study. Demographic factors; systemic risk factors; central macular thickness (CMT), subfoveal choroidal thickness (SFCT), linear extent of ellipsoid zone (EZ) and interdigitation zone damage on optical coherence tomography; details of leak on fluorescein angiography and indocyanine green angiography were included as predictors of anatomical and visual outcomes.
Multicolor imaging in macular telangiectasia-a comparison with fundus autofluorescence.
Graefes Arch Clin Exp Ophthalmol
November 2020
Purpose: To describe various clinical features of idiopathic juxtafoveal retinal telangiectasis group 2A or idiopathic macular telangiectasia type 2 (MacTel) on multicolor imaging (MCI) and compare imaging findings of MacTel on MCI with fundus autofluorescence (FAF).
Methods: Patients with a clinical diagnosis of MacTel based on Gass and Blodi's classification were included. FAF and MCI images were graded qualitatively for stage of disease, margins of involvement, hyperautofluorescence on FAF (corresponding retinal atrophy on MCI), and detection of crystals.
Background: To report the clinical and angiographic characteristics of choroidal neovascularization in patients with diabetic retinopathy.
Methods: Patients of type 2 diabetes mellitus with presence of choroidal neovascularization in at least one eye were retrospectively analyzed. The study eyes were divided into three groups based on presence (active or scarred) or absence of choroidal neovascularization (fellow eyes).
Central serous chorioretinopathy (CSCR) is characterised by choroidal hyperpermeability which results in neurosensory detachments (NSD) along with numerous retinal pigment epithelium (RPE) alterations such as RPE atrophy. Fundus autofluorescence (FAF) demonstrates the functionality of the RPE while multicolor imaging(MCI), by means of its three incident wavelengths, provides insight into clinical changes at various levels of the retina and choroid in CSCR. This study compares various clinical findings in CSCR (NSD, subretinal deposits, RPE atrophy, pigment epithelial detachments (PED) and pachyvessels) on the above mentioned imaging modalities both qualitatively and quantitatively.

Methods: This was a multicentre, retrospective, interventional case series which included treatment-naïve cases of peripapillary choroidal neovascular membrane (CNVM) with a minimum follow-up of 12 months. Multimodal imaging which comprised optical coherence tomography (OCT), fluorescein angiography and/or indocyanine green angiography was performed at baseline and follow-up visits.
