Summary
Glaucoma surgeons found the ab-interno gelatin microstent easier to learn than traditional filtration surgery. Most surgeons gained comfort after 6-10 cases, highlighting the microstent
Area of Science:
- Ophthalmology
- Glaucoma Surgery
- Surgical Education
Background:
- The ab-interno gelatin microstent (XEN-45) offers a minimally invasive approach to glaucoma management.
- Evaluating surgeon learning curves is crucial for adopting new surgical techniques.
Purpose of the Study:
- To assess Canadian surgeons' learning experience with the ab-interno gelatin microstent.
- To compare the learning curve of the gelatin microstent to traditional glaucoma surgeries.
Main Methods:
- A cross-sectional survey study was conducted among Canadian surgeons using the XEN-45 microstent.
- An anonymous online survey evaluated surgical experience, patient selection, surgical steps, and postoperative care.
- The survey was validated by 3 experienced glaucoma surgeons.
Main Results:
- Surgeons were generally experienced, with most comfortable performing filtration surgery.
- The scleral tunnel creation was identified as the most challenging surgical step.
- A majority of surgeons (52.9%) needed 6-10 cases to achieve proficiency and found the microstent easier to learn than traditional filtration surgery (94.1%).
Conclusions:
- Glaucoma surgeons reported a favorable learning experience with the ab-interno gelatin microstent.
- Proficiency with the XEN-45 microstent was perceived as more attainable compared to traditional filtration procedures.

The psychodynamic perspective in psychology asserts that most personality functions operate unconsciously, outside of awareness. This means that the motives and emotions driving behavior often remain hidden, automatically buried in the unconscious mind as a defense mechanism to shield us from psychological distress. According to this theory, the unconscious mind contains thoughts, memories, and emotions that are too disturbing to face directly.

Social cognitive perspectives on personality emphasize the importance of conscious awareness, beliefs, expectations, and goals in shaping behavior. These perspectives incorporate behaviorist principles, such as learning through reinforcement and conditioning, but extend beyond them by highlighting human reasoning and planning. Unlike traditional behaviorist views, social cognitive theory focuses on how individuals reflect on their past experiences and plan for future outcomes by considering...

In a study where individuals posing as strangers offered compliments and proposed casual sex to students, the responses differed significantly based on gender. Not a single woman accepted the proposal, while 70% of the men agreed. This outcome provides a useful scenario to explore through the lens of evolutionary psychology and social learning theory, highlighting the diverse perspectives on human sexual behaviors.

01:19The Behavioral Perspective on Personality
846
Behaviorists view personality as primarily shaped by environmental reinforcements and consequences. According to this perspective, behavior is influenced by external stimuli, and individuals adjust their actions based on rewards and punishments. Over time, learning histories — accumulated patterns of reinforcement — play a significant role in shaping personality. Behaviors that lead to positive outcomes are reinforced, while those resulting in negative outcomes are diminished.

01:14Avoidance Learning and Learned Helplessness
2.6K
Avoidance learning and learned helplessness are critical concepts in understanding behavioral responses to negative stimuli.
Avoidance learning occurs when an organism learns that a specific behavior can prevent an unpleasant outcome. For example, a student who receives a bad grade may start studying harder to avoid future poor grades. This behavior persists even when the negative outcome is no longer present. Avoidance learning is powerful because it maintains behavior in the absence of the...

The first thing a clinician sees is the skin, so the examination of the skin should be part of any thorough physical examination. Most skin disorders are relatively benign, but a few, including melanomas, can be fatal if untreated. A couple of the more noticeable disorders, albinism and vitiligo, affect the appearance of the skin and its accessory organs.
