Summary
Acquired symptomatic external punctal stenosis (EPS) is common in Kuwait, affecting over 70% of patients with epiphora. Aging and female sex are key risk factors for this condition.
Area of Science:
- Ophthalmology
- Oculoplastics
Background:
- Acquired symptomatic external punctal stenosis (EPS) is a condition causing excessive tearing.
- Its prevalence and associated factors are not well-established in Kuwait.
Purpose of the Study:
- To determine the prevalence of acquired symptomatic external punctal stenosis (EPS).
- To identify risk factors, etiologies, and management outcomes for EPS in Kuwait.
Main Methods:
- A prospective, hospital-based study conducted in Kuwait from November 2018 to November 2019.
- Included 418 patients aged over 18 with symptomatic epiphora and specific punctal characteristics.
- Excluded congenital causes, prior eyelid surgeries, and traumatic/neoplastic obstructions.
Main Results:
- The prevalence of EPS was 70.3% among referred patients.
- Tangential puncta shape was most common (65.3%).
- Bilateral involvement occurred in 70.1% of cases; treatments included dilatation, syringing, and Mini-Monoka tube placement.
Conclusions:
- EPS is a frequent cause of symptomatic epiphora.
- Aging and female sex are significant risk factors.
- Inflammatory mechanisms are implicated; population-based studies are needed for precise prevalence data.

01:28Peptic Ulcer Disease III: Clinical Manifestations and Diagnostic Studies
Peptic ulcer disease (PUD) presents with diverse symptoms depending on the location and severity of the ulcer. Clinical manifestations of peptic ulcer include dull pain and a burning sensation in the mid-epigastric region.
Few clinical manifestations differentiate gastric ulcers from duodenal ulcers. Distinctions in the location, timing, and pain relief are crucial for healthcare providers in differentiating between gastric and duodenal ulcers during clinical assessments.

Diagnosing acute coronary syndrome or ACS begins with a thorough patient history. Notable symptoms include central, crushing chest pain radiating to the left arm, neck, jaw, or back, along with shortness of breath, sweating (diaphoresis), nausea, vomiting, dizziness, and palpitations.It is crucial to note any history of cardiac illnesses and assess risk factors, including age, gender, smoking, hypertension, diabetes, hyperlipidemia, and a sedentary lifestyle.During physical examination, vital...
01:30Hypertension III: Clinical Manifestations and Diagnostic Studies
Hypertension is asymptomatic and also referred to as the "silent killer" until it progresses to a severe stage or causes target organ disease. Patients may experience symptoms stemming from the strain on blood vessels and tissues in various organs or the heart's increased workload.Physical exams might show no abnormalities other than high blood pressure. Signs of vascular damage, when present, correspond to the organs supplied by the affected vessels, leading to target organ damage. For...
01:21Peripheral Arterial Disease II: Clinical Manifestations and Diagnostic Evaluation
Clinical manifestationsPeripheral Arterial Disease (PAD) manifests through a range of symptoms, from the characteristic intermittent claudication to atypical presentations and severe complications in advanced stages. Intermittent claudication, a hallmark symptom of PAD, presents as exercise-induced muscle pain that typically resolves within minutes of rest. This pain is reproducible and stems from inadequate blood flow, leading to the accumulation of lactic acid produced during anaerobic...
