Study Notes

Retinal Concerns

Flashes and floaters pose a greater risk when unilateral, indicating potential retinal tear or detachment.
Acute occurrences are more concerning than chronic conditions.
Ocular surgeries, like cataract extraction, increase the risk of retinal tears and detachments.
Superior findings are more concerning due to gravitational factors affecting traction from the vitreous.

Diagnostic Signs

Prior retinal surgery may result in pigment presence in the vitreous.
If a patient shows flashes/floaters and a positive Schafer’s sign without retinal tears, immediate referral and follow-up are necessary to check for potential holes or tears.

Types of Retinal Tears and Holes

Horseshoe tears with anterior flaps indicate significant concern due to proximity to the ora.
Retinal holes are round and well-defined; they do not typically exhibit fluid or traction and are less concerning than tears.
Chronic holes may present with signs of atrophy and pigmentation, indicating they are less acute.
Newer holes exhibit fluid cuffs and lack pigment, suggesting a higher concern for potential retinal damage.

Retinal Detachment Pathophysiology

Highly myopic patients with a posterior vitreous detachment (PVD) experience reduced retinal traction, possibly indicating safeness compared to those without PVD.
Many retinal detachments commence from a tear leading to a more serious condition.

Emergency Considerations

Retinal detachments are urgent conditions that require prompt assessment.
Patients may need to be directed to emergency services or scheduled for private appointments, ensuring they have relevant information for follow-up.

Referral Protocols

Provide patients with contact details for their surgeon and specific anatomical details about their condition to ensure clear communication for specialists.
Accurate descriptions, even if uncertain, are crucial for specialist assessment.

Treatment Options

Cryopexy involves freezing the retinal tear and creating scar tissue to seal it, requiring anesthesia and sometimes conjunctival incision for access.
Successful cryotherapy produces a swelling effect at the treated area, leading to necessary scarring.

Laser Therapy

Advanced procedures involving retinal lasers will cover application techniques, power regulation, and spot size adjustments during practical sessions.
Familiarization with retinal laser machines will enhance procedural confidence and understanding of retinal treatments.

Key Considerations for Future Practice

Clear communication enhances patient outcomes and specialist collaboration.
Recognizing and addressing retinal concerns in a timely manner is essential for preserving vision.
