Lactoferrin (LF) is a first-line defense protein with a pleiotropic functional pattern that includes anti-inflammatory, immunomodulatory, antiviral, antibacterial, and antitumoral properties. Remarkably, this iron-binding glycoprotein promotes iron retention, restricting free radical production and avoiding oxidative damage and inflammation. On the ocular surface, LF is released from corneal epithelial cells and lacrimal glands, representing a significant percentage of the total tear fluid proteins. Due to its multifunctionality, the availability of LF may be limited in several ocular disorders. Consequently, to reinforce the action of this highly beneficial glycoprotein on the ocular surface, LF has been proposed for the treatment of different conditions such as dry eye, keratoconus, conjunctivitis, and viral or bacterial ocular infections, among others. In this review, we outline the structure and the biological functions of LF, its relevant role at the ocular surface, its implication in LF-related ocular surface disorders, and its potential for biomedical applications.

Department of Ophthalmology, Hospital Sultan Idris Shah, Serdang, Malaysia.
Purpose: To highlight a case report of high-grade primary lacrimal sac Burkitt lymphoma in a young adult.
Observation: A 25-year-old gentleman was referred to the oculoplastic center for left eye medial canthal progressive swelling at the level below the medial canthal tendon for two months associated with tearing. He was initially treated for preseptal cellulitis but failed to respond to antibiotics.

Purpose: To evaluate the efficacy and safety of intense pulsed light (IPL) combined with meibomian gland expression (MGX) for the treatment of dry eye disease and meibomian gland dysfunction associated with chronic Stevens-Johnson syndrome and toxic epidermal necrolysis.
Methods: This prospective noncomparative interventional study included 29 patients (58 eyes) who underwent 3 sessions of IPL and MGX at 2-week intervals. Subjective symptoms (ocular surface disease index score) and objective dry eye tests: matrix metalloproteinase 9, tear meniscus height, bulbar redness score, tear film lipid layer thickness (LLT), Schirmer I test, conjunctival and corneal staining, meibomian gland loss, MGX score [meibomian gland score (MGS)], and tear break-up time were assessed at the baseline and after 4, 8, and 12 weeks.

Purpose: To assess the impact of autologous serum (AS) tears at a 50% concentration on the ocular surface of patients with refractory dry eye disease (DED) because of Sjogren syndrome.
Methods: Twenty eyes of ten patients with severe immune-mediated DED were contralaterally randomized to receive either AS tears 50% or artificial tears between June 2021 and May 2023. Changes in tear stability, ocular surface staining, and in the morphology of the corneal sub-basal nerves were evaluated before treatment and at 1, 2, and 3 months after treatment using objective tests for DED and confocal microscopy.

Purpose: Ocular rosacea is a chronic inflammatory disorder affecting the ocular surface, often associated with cutaneous rosacea. This review aims to explore its pathogenesis, treatment approaches, and future directions for management.
Methods: A review of current literature on the pathophysiology, clinical features, and treatment strategies of ocular rosacea in adults and children (pediatric blepharokeratoconjunctivitis) was conducted.

Significance: Cataract surgery is one of the most performed surgical procedures worldwide. As a potential complication following cataract surgery, dry eye has the potential to impact visual outcomes, lower patient satisfaction, and be detrimental to quality of life.
Purpose: To evaluate the effect of cataract surgery on dry eye outcomes postoperatively.
