|March 2, 2018
Summary
This study found 63% surgical success for consecutive exotropia using one-muscle surgery. Preoperative medial rectus underaction increases the risk of abnormal scleral attachment, impacting outcomes.
Area of Science:
- Ophthalmology
- Strabismus Surgery
- Histopathology
Background:
- Consecutive exotropia can present complex surgical challenges.
- Understanding scleral attachment abnormalities is crucial for surgical planning.
Purpose of the Study:
- To investigate clinical and histopathologic features of consecutive exotropia.
- To evaluate surgical outcomes and risk factors for abnormal scleral attachment.
Main Methods:
- Thirty patients with consecutive exotropia underwent unilateral medial rectus resection and advancement.
- Abnormal scleral attachment was documented and compared with histopathology.
- Surgical success was defined as <10 PD deviation at 6 months.
Main Results:
- Sixty-three percent of patients achieved surgical success.
- Forty percent of cases showed abnormal scleral attachment.
- Preoperative medial rectus underaction was a risk factor for abnormal scleral attachment.
Conclusions:
- One-muscle surgery achieved 63% success in consecutive exotropia.
- Dose-responses can aid surgical planning.
- Preoperative medial rectus underaction increases the risk of abnormal scleral attachment.

1
Toxidromes are specific patterns of symptoms resulting from toxic substance exposure. They help in the identification and treatment of poisoning. The symptoms of each toxidrome group indicate poisoning by a certain class of chemicals or drugs.1. Sympathomimetic: Stimulates the sympathetic nervous system. Symptoms include agitation, increased heart rate (HR), blood pressure (BP), respiratory rate (RR), temperature, and pupil size. Drugs like cocaine and amphetamines, along with tremors and...

01:20COPD: Pathogenesis and Clinical Features
1.9K
Chronic obstructive pulmonary disease (COPD) is a group of lung conditions that progressively worsen over time, including chronic bronchitis and emphysema. This cluster of diseases collectively leads to a gradual and irreversible decline in lung function over time.
The primary cause for the onset of COPD is cigarette smoking and exposure to air pollution. These hazardous factors initiate a chain reaction within the lungs, resulting in chronic inflammation, damage to the airways, and a...

Patients with esophageal strictures often experience a range of symptoms. Initially, they may have difficulty swallowing solid foods, which can progress to include liquids. Additional symptoms may involve chest pain or discomfort, regurgitating food and fluids, heartburn, unintentional weight loss, coughing or choking during meals, and hoarseness.
Healthcare providers should gather a comprehensive medical history and conduct a physical examination for diagnosis. If esophageal stricture is...

Endocarditis can present various clinical features depending on the causative organism and the patient's underlying health conditions. Initially, the clinical features of infective endocarditis develop gradually, presenting with nonspecific symptoms that can be easily mistaken for other illnesses.General SymptomsEarly symptoms of infective endocarditis are fever, chills, weakness, malaise, fatigue, and weight loss. These symptoms reflect the systemic nature of the infection and the body's...

Pericarditis is distinguished by inflammation of the pericardium, the fibrous sac that encases the heart. It can be acute, lasting less than six weeks, or chronic, persisting for over three months. Understanding its clinical manifestations and diagnostic findings is crucial for timely and effective management.Clinical ManifestationsWhile pericarditis can be asymptomatic, it usually presents with characteristic symptoms such as:Chest Pain: The most characteristic symptom of pericarditis is chest...

Myocarditis is an inflammation of the heart muscle. The symptoms vary widely, encompassing asymptomatic presentations to severe, acute manifestations.Clinical PresentationAsymptomatic cases: In some instances, myocarditis may be asymptomatic, with the infection resolving without intervention. These cases often go undetected unless discovered incidentally through diagnostic imaging or tests conducted for other reasons.General Early Symptoms: Early symptoms of myocarditis are non-specific and can...
