Trauma-induced retinal detachment associated with giant retinal tears

Area of Science:

• Ophthalmology
• Retinal Surgery
• Trauma Care

Background:

• Giant retinal tears (GRTs) can be spontaneous or associated with ocular trauma.
• Approximately 25% of GRTs are linked to eye injuries.
• Understanding outcomes of traumatic GRTs is crucial for surgical planning.

Purpose of the Study:

• To present clinical findings and surgical outcomes of traumatic giant retinal tears.
• To evaluate the efficacy of surgical management for these injuries.
• To compare results with spontaneous GRTs.

Main Methods:

• Retrospective review of 38 cases of traumatic GRT at Moorfields Eye Hospital over 10 years.
• Analysis of patient demographics, trauma type (penetrating vs. non-penetrating), and surgical procedures.
• Assessment of surgical success (reattachment rates) and visual acuity outcomes.

Main Results:

• The study population comprised young males (mean age 29) with predominantly non-penetrating trauma (63%).
• Pars plana vitrectomy and fluid-silicone oil exchange were the primary surgical interventions.
• An 89% reattachment rate was achieved at 12 months, though penetrating trauma cases had lower success rates.
• Raised intraocular pressure occurred in 32% of cases.
• Mean final visual acuity was 6/36, with a wide range from 6/6 to no light perception.

Conclusions:

• Surgical management, primarily vitrectomy with silicone oil, yields favorable reattachment rates for traumatic GRTs.
• Penetrating trauma is associated with poorer surgical outcomes.
• Outcomes appear comparable to those reported for spontaneous GRTs, highlighting the effectiveness of current surgical techniques.
