Dacryology and Dry Eye

The Dacryology and Dry Eye field focuses on the anatomy, physiology, pathology, and management of the lacrimal system and tear film dynamics. Disorders of tear production, drainage, and ocular surface stability are among the most common causes of patient discomfort and visual disturbance in clinical practice. At a major Ophthalmology Conference, this topic highlights the expanding scientific understanding of tear film dysfunction, chronic dry eye disease, and lacrimal drainage abnormalities. As modern lifestyles increase digital screen exposure and environmental stressors, the prevalence of dry eye continues to rise globally.

Dry eye disease is multifactorial, involving tear film instability, hyperosmolarity, inflammation, neurosensory abnormalities, and meibomian gland dysfunction. Symptoms such as burning, foreign body sensation, fluctuating vision, and photophobia significantly impact quality of life. Accurate diagnosis relies on tear breakup time assessment, Schirmer testing, ocular surface staining, osmolarity measurement, and meibography imaging. Advances in diagnostic biomarkers are improving differentiation between aqueous-deficient and evaporative dry eye subtypes.

Dacryology also encompasses lacrimal drainage disorders including nasolacrimal duct obstruction, canalicular stenosis, and congenital anomalies. Chronic epiphora and recurrent infections may require surgical intervention such as dacryocystorhinostomy or minimally invasive lacrimal procedures. Endoscopic approaches have improved surgical precision while reducing recovery time.

Therapeutic strategies for dry eye disease range from lubricating agents and anti-inflammatory medications to advanced treatments such as intense pulsed light therapy and thermal pulsation systems for meibomian gland dysfunction. Biologic therapies, autologous serum tears, and novel anti-inflammatory agents are emerging as promising options for refractory cases. Lifestyle modifications, environmental adjustments, and patient education remain central to long-term disease control.

Research continues to explore the immunological basis of ocular surface inflammation and the role of neurosensory feedback in chronic symptoms. Artificial intelligence–assisted imaging tools are enhancing gland morphology analysis and tear film evaluation. With increasing awareness of digital eye strain and environmental influences, preventive strategies are gaining prominence in both clinical and occupational health settings.

By integrating lacrimal anatomy, ocular surface biology, and minimally invasive surgical innovation, this area advances patient-centered solutions for comfort, visual stability, and improved ocular surface health.
