The human ocular surface hosts a bacterial assemblage that integrates a diverse and complex microbiome. This bacterial microbiota is part of a healthy eye and plays a protective role in it. However, this ocular bacterial assemblage may alter the ocular surface inflammation response and can influence the development and progression of dry eye disease. For this reason, the present review describes the changes generated on the ocular surface by bacterial assemblages during the development of dry eye disease. Likewise, the interaction of this microbiota with the other inflammatory factors that influence the development of this disease is analyzed, as well as the use of treatments focused on modifying the bacteria on the ocular surface.

Purpose: This study was designed to investigate risk factors for the development of cytomegalovirus (CMV) corneal endotheliitis following corneal transplantation.
Methods: We retrospectively analysed 1225 corneal transplants for bullous keratopathy between 2011 and 2021. 31 cases who were administered the treatment of CMV corneal endotheliitis preoperatively were excluded, and 1194 cases were analysed for risk factors for the development of CMV corneal endotheliitis following corneal transplantation.

: Diabetes is a well-recognised factor inducing a plethora of corneal alterations ranging from dry eye to reduced corneal sensibility, epithelial defects, and reduced cicatrisation. This cohort study aimed to assess the efficacy of a novel ophthalmic solution combining cross-linked hyaluronic acid (CHA), chondroitin sulfate (CS), and inositol (INS) in managing diabetes-induced corneal alterations. Specifically, it evaluated the solution's impact on the tear breakup time (TBUT), the ocular surface disease index (OSDI), and corneal sensitivity after three months of treatment.

To compare the long-term efficacy and safety of intense pulsed light (IPL) treatments using a 590-nm and an acne filter. In this prospective, randomized, paired-eye trial study, 30 patients with moderate and severe meibomian gland dysfunction (MGD) were followed up for at least one month after their last treatment. Group A received IPL treatment with an acne filter, a type of notch filter that blocks wavelengths between 600 and 800 nm, allowing IPL to emit wavelengths between 400-600 nm and 800-1200 nm.

Dry eye disease (DED) is a multifactorial, chronic, and often relapsing condition with a significant impact on patient quality of life (QoL). Symptoms such as ocular discomfort and visual disturbances are diverse and frequently misaligned with objective clinical signs, complicating diagnosis and management. DED not only interferes with daily activities like reading, driving, and computer use but also imposes a substantial economic burden due to direct healthcare costs and reduced work productivity.

Sensitivity to ocular irritation varies among individuals, being influenced by clinical, subjective, and biochemical factors. This study aimed to evaluate individual variability in ocular irritation sensitivity, focusing on clinical parameters, pain perception, and tear neuromediator profiles. Sixty female participants aged 20-40 were classified into high-sensitivity and low-sensitivity groups based on their response to an irritant (Tween20).
