Retinal injuries associated with cataract surgery

Area of Science:

• Ophthalmology
• Surgical Complications
• Retinal Diseases

Background:

• Cataract surgery is a common procedure with a low complication rate.
• Retinal trauma is a rare but serious complication that can impact visual outcomes.
• Understanding the mechanisms of retinal injury is vital for prevention and management.

Observation:

• Five patients experienced retinal trauma during cataract surgery.
• Two cases involved globe perforation by retrobulbar injection needles.
• One case resulted from superior rectus muscle bridle suture perforation.
• Retinal dialysis occurred in two cases, one from a stab incision during expulsive choroidal hemorrhage, and another from vitreous aspiration.

Findings:

• Specific surgical actions, including needle injections and suture placement, can directly cause retinal injury.
• Expulsive choroidal hemorrhage and vitreous loss are associated with specific types of retinal trauma like dialysis.
• The mechanisms of injury are varied, highlighting different vulnerable points during surgery.

Implications:

• Highlights the importance of meticulous surgical technique during cataract surgery.
• Emphasizes the need for heightened awareness and vigilance regarding potential retinal trauma.
• Suggests potential modifications in surgical approaches or needle/suture techniques to mitigate risks.
