Article Abstract
Purpose: Conjunctivitis is one of the most common ocular conditions in clinical practice. Human adenoviruses have been the common causative agents known to cause epidemic kerato-conjunctivitis (EKC) in India from 1996 to 2019 with a positivity range of 13.8%-65.2%. The current study was initiated to throw light on the distribution of keratoconjunctivitis causing agents across India covering a span of 3 years.
Methods: A total of 709 swabs were collected from patients in viral transport medium (VTM), and real-time PCR was done to identify agents including Adenovirus (HAdV), Enterovirus, HSV, and Chlamydia.
Results: 47.8% of the samples were positive for HAdV followed by HSV (3.4%), Enterovirus (2.7%), and Chlamydia (0.6%). Overall, 386 people (54.4%) tested positive for one of these infections, with Chandigarh (88.4%) and Port Blair (71.7%) showing higher positivity rate. Pre-auricular lymphadenopathy and follicles were significantly associated with increased risk of conjunctivitis.
Conclusion: Epidemiology of keratoconjunctivitis in the current study revealed HAdV to be predominant causative agent. Knowledge gained in such epidemiological studies guide us in outbreak expectations, limit antibiotic over-prescription, and enhance disease prevention.

Sicca syndrome (dry mouth and dry eyes) occurs predominantly due to the side effects of medication, systemic diseases (Sjögren's disease), and radiotherapy of the head and neck region. Sicca complaints decrease the quality of life, cause sleep disturbances, and affect overall health. This systematic literature review investigates the correlation and/or association between dry mouth and dry eyes.

Background: Keratoconjunctivitis sicca, or the dry eye disease (DED) is prevalent multifactorial disorder of the tears and ocular surface, which has lately been interested scholars, particularly in establishing its link with diabetes mellitus (DM). This study aimed to evaluate the association between DM and DED through a comprehensive systematic review and meta-analysis of existing published articles, and thus understand the attributed risks for DED development in diabetic patients.
Methods: Four databases, PubMed, Cochrane Library (CENTRAL), Web of Science, and Google Scholar, were electronically searched for relevant publications.

Human herpes virus infection is thought to be associated with the development of vestibular neuritis (VN); however, the causal relationship is unclear. Large-scale genome-wide association studies were used in bidirectional Mendelian randomization (MR) analyses to evaluate the causal relationship between human herpes virus infections and VN in a cohort of 434,070 individuals. Inverse variance weighting, MR-Egger, and weighted median methods were used to estimate causality.

Numerous cases of infectious keratoconjunctivitis (IKC) have been recently observed in European bison in Poland. The present study aimed to identify the ocular surface microbiota of European bison and determine if bacterial communities differed between animals with and without IKC. Ocular swabs were collected from the conjunctiva and cornea of 57 European bison with IKC and 30 healthy animals, from southern and northeastern Poland.
