Aims: To assess the course of tear gland function of patients with keratoconjunctivitis sicca (KCS) associated with primary (KCS-PSS) or secondary Sjögren's syndrome (KCS-SSS), and of patients with KCS not related to Sjögren's syndrome (KCS-NS).
Methods: In 106 patients with dry eye an ophthalmic diagnosis of KCS was made. Subsequent evaluations revealed a diagnosis of KCS-PSS in 31, KCS-SS in 19, and KCS-NS in 56 patients. Follow up assessments have been performed 10-12 years after initial diagnosis.
Results: At baseline and at follow up tear gland function tests were worse in patients with KCS-PSS compared with the other forms of KCS. At follow up in the KCS-SSS patient group the tear gland function variables returned to marginal normal limits. In contrast with expectation, a marked improvement of the tear gland function variables in the KCS-NS patient group was noted.
Conclusions: In KCS-PSS patients tear gland function is characterised by a steady state situation. In KCS-SSS patients the normalisation of tear gland function variables most probably reflects a remission of the underlying disease. In view of the overall improvement in KCS-NS patients the term age related KCS should be avoided.

: The aim of the present study was to establish a cut-off value of the Lipid Layer Pattern (LLP) between participants with different subtypes of Dry Eye Disease (DED) including Deficient Dry Eye (ADDE), Evaporative Dry Eye (EDE), and Mixed Dry Eye (MDE). : 240 participants diagnosed with DED according to the Tear Film and Ocular Surface Society in the Dry Eye Workshop II guidelines were included in the study. Tear Meniscus Height (TMH) using the Tearscope illumination and Meibomian Gland Loss Area (MGLA) using the Keratograph 5M were assessed to categorize the participants into an ADDE group, EDE group, or MDE group.

Morphological analysis of lacrimal punctum using anterior segment optical coherence tomography in different age groups.
Indian J Ophthalmol
February 2025
Department of Orbit and Oculoplasty, Sankara Eye Hospital, Coimbatore, Tamil Nadu, India.
Purpose: To evaluate the lacrimal punctal changes in different age groups using anterior segment optical coherence tomography (AS-OCT).
Methods: A cross-sectional observational study was conducted between January 2023 and January 2024 including healthy subjects between 20 and 80 years. The selected eyes from healthy patients were divided into four age groups (21-35 years, 36-50 years, 51-65 years, 66-80 years), and lower lacrimal puncta were analyzed using AS-OCT.

Purpose: To investigate the effect of S-100 absorbable hemostatic patch coverage on anastomotic mucosa in endonasal endoscopic dacryocystorhinostomy (En-DCR).
Methods: Two hundred and twenty-six patients with unilateral chronic dacryocystitis (CD) were randomly divided into two groups in a randomized controlled trial: the S-100 absorbable hemostatic patch group (group A) and the control group (group B). All patients underwent En-DCR.

Beijing Institute of Ophthalmology, Beijing Tongren Eye Center, Beijing Tongren Hospital, Capital Medical University; Beijing Ophthalmology & Visual Sciences Key Laboratory, Beijing, People's Republic of China.
Objectives: To address the lack of nerve and blood supply after labial salivary gland transplantation (LSGT) resulting in glandular atrophy. We designed a modified LSGT, called insular infraorbital neurovascular pedicle LSGT, and evaluated the postoperative efficacy.
Design: This is a prospective, single-centre, self-contained study.
