ABSTRACT In summary, full-thickness peripheral retinal tear is classified in relationship to the vitreous base as intrabasal, juxtabasal and extrabasal. Each of these categories of full-thickness retinal tear is usually associated with characteristic lesions that are particularly likely to produce full-thickness retinal tears in the respective zones. In overall prevalence, full-thickness peripheral retinal tears, excluding retinal tears at the ora serrata, are present at autopsy in 3.3% of patients, are bilateral in 11.2% of affected patients, and are present in 1.9% of eyes. In conjunction with full-thickness retinal tears, principles of management are reviewed. Author.

ABSTRACT Giant retinal tears may arise spontaneously, but approximately 25% occur in association with ocular trauma. The clinical findings and results of surgical management in 38 cases of traumatic giant retinal tear seen at Moorfields Eye Hospital in London during a 10-year period are presented. Patients were young (mean age = 29 years) and mostly men (n = 36; 95%). Trauma was penetrating in 14 eyes (37%) and nonpenetrating in 24 (63%). Initial surgical management consisted of pars plana vitrectomy and fluid-silicone oil exchange in the majority of cases. Lensectomy was performed for opacity or dislocation in 23 (61%) eyes. Reattachment was achieved in 34 (89%) eyes 12 months after surgery. Most of the surgical failures occurred in eyes with penetrating trauma. Raised intraocular pressure was an associated problem that required treatment in 12 (32%) eyes. Visual acuity at final follow-up examination ranged from 6/6 to no perception of light (NPL; mean = 6/36). These results compare favorably with published figures for the treatment of spontaneous giant retinal tears. Author.

ABSTRACT PURPOSE:

Analysis of the clinical and therapeutic results of giant retinal tears after ocular blunt trauma.

PATIENTS AND METHODS:

We performed a retrospective review of nine patients with giant retinal tears associated to retinal detachment after ocular blunt trauma. The traumatic giant retinal tear was a peripheral break of 90 degrees or greater. Seven patients had myopia. Primary management of retinal detachment included, scleral buckling and external drainage of subretinal fluid, in 2 cases. Vitrectomy with fluid-silicone oil exchange was used in 7 cases and perfluorodecalin in 3 cases.

RESULTS:

Our results indicate that myopia was the principal risk factor of blunt trauma retinal tears, which appear even when the contusion was not too violent or indirect. Successful results were not obtained with episcleral surgery alone (2 cases). With primar vitrectomy, the success rate was 57%. The overall success rate was 66.6% with an average acuity of 2/10.

CONCLUSION:

High myopia is the principal risk factor of giant retinal tear after blunt ocular trauma. The prognosis of this retinal detachment depends on the grade of proliferative vitreoretinopathy. Author.
