Retinal venous-venous anastomoses and capillary aneurysms in juvenile glaucoma.

Two patients with juvenile glaucoma, a 12-year-old boy and a 22-year-old woman, were noted to have venous-venous anastomoses and capillary aneurysms of the retina. Their intraocular pressures had exceeded the diastolic pressure of the central retinal artery for months. Accompanying the successful surgical reduction of the intraocular pressures, these changes in the retinal vessels promptly reverted or disappeared. We consider that these capillary aneurysms and venous-venous anastomoses are the sequelae of the prolonged elevation of the intraocular pressure.
