RESUMEN
Immersion A- and B-scan ultrasonography was performed before vitreous surgery in 256 eyes with diabetic vitreous hemorrhage. Of 32 eyes with vitreous hemorrhage without vitreous traction (group 1), 28 (88%) showed useful postoperative vision. Of 87 eyes with vitreous traction without tractional retinal detachment (group 2), 69 (79%) had useful postoperative vision. Eyes with tractional retinal detachments were classified as follows: X-shaped detachment with narrow vitreoretinal adhesions (group 3, 75 eyes), and H-shaped detachment with broad vitreoretinal adhesions (group 4, 62 eyes). Useful postoperative vision returned in 43 eyes in group 3 (57%) and in only 14 eyes in group 4 (23%), a statistically significant difference. Visual improvement was greater in groups 1 and 2 than in groups 3 and 4. Postoperative functional results were worse when the macular area was the site of vitreoretinal adhesion and traction.

Choroidal osteoma is a rare entity, reported previously mainly in females. We report a case of bilateral choroidal osteoma in a 15-year-old boy. Ultrasonography and computerized tomography findings were key to establishing the diagnosis. During two years' follow-up, there was observable growth in the tumor size. Leakage from subretinal neovascular tufts covering the tumor caused visual deterioration. Photocoagulation of the subretinal new vessels was performed twice, with limited success, but the value of this treatment in choroidal osteomas needs further study.
