Allergic rhinitis, commonly known as hay fever, is a hypersensitivity reaction of the nasal mucosa to allergens such as pollen, dust mites, pet dander, or mold spores. Beyond nasal symptoms, a significant subset of patients experience ocular symptoms associated with allergic rhinitis, which can substantially impair quality of life. These symptoms often involve inflammation of

Obstructive Sleep Apnea Syndrome (OSA) is a serious sleep-related breathing disorder characterized by repetitive episodes of upper airway obstruction during sleep. These episodes, often associated with a reduction (hypopnea) or complete cessation (apnea) of airflow, lead to fragmented sleep, intermittent hypoxemia, and excessive daytime sleepiness. OSA poses significant health risks, including cardiovascular disease, cognitive impairment,
Obstructive pulmonary disease is a chronic respiratory disorder characterized by airflow limitation due to airway obstruction. This limitation is typically progressive and not fully reversible, significantly impacting pulmonary function and quality of life. The term most commonly refers to Chronic Obstructive Pulmonary Disease (COPD), which includes both chronic bronchitis and emphysema. Accurate diagnosis, early intervention,
