[Ocular blood flow and characteristics of retinal detachment].

Purpose: To determine if ocular blood flow (OBF) changes in retinal detachment (RD) are related with its characteristics (extension, macular involvement, PVR or duration).

Methods: 60 patients with unilateral rhegmatogenous RD and 20 <> patients were selected. Color Doppler Ultrasound was used to measure OBF velocities in the ophthalmic artery (OA), central retinal artery (CRA) and vein (CRV) and posterior ciliary arteries (PCA) of both eyes of each patient.

Laser interferometry: preoperative functional predictive value in retinal detachment.

Purpose: To determine the functional predictive value of laser interferometry (LI) in retinal detachment (RD).

Methods: Laser interferometry with test field diameters of 3 degrees and 8 degrees, both with and without light, was tested preoperatively in 42 eyes with rhegmatogenous RD that were candidates for scleral buckling. Snellen visual acuity (VA) and LI (four test fields) were tested preoperatively and postoperatively (1 week, and 1, 3, and 7 months).
