Controlled vacuumed drainage of subretinal fluid is achieved using a 25 gauges butterfly needle and a syringe. This technique often totally flattens the retina during the operation. It seems particularly indicated in inferior retinal detachment without break.

This study was designed to improve the understanding of the mechanisms that govern the origin of retinal detachment (RD) by examining the quantitative composition of proteins in the subretinal fluid (SRF). Inflammation proteins and immunoglobulins (Ig) were titrated from SRF and sera in 25 patients with RD The following concentrations were found in SRF: total proteins 16 g/l, albumin 12.6 g/l; pre-albumin 0.37 g/l; transferin 1.8 g/l in 68% of cases; haptoglobin and alpha 2 macroglobin were present in only one SRF: alpha 1 antitrypsin 0.86 g/l in 48%; orosomucoid 0.57 g/l in 32%; IgG 2 g/l in 52%; IgA 0.17 g/l in 88% and IgM 15.9 mg/l in 56%. Correlations were found between the duration of detachment and the concentration of total proteins (p < 0.01). The extent of RD was correlated with the concentration of IgG or IgA in the SRF (p < 0.01). These findings suggest that the correlation between the Ig concentration and the extent of RD is an argument for the participation of choriocapillaris in the genesis of SRF.
49 eyes with pseudophakic retinal detachments are operated with 44 good anatomic results (90% success). These detachments are characterised by the high frequency of anterior proliferative vitreoretinopathy.
The authors study an observation of unusual localisation, near the optic disc, of periphlebitis associated to multilocular sclerosis. There are some cicatricial periphlebitis and active others, which are more peripheral, alone without any uveitis. These ones resolved in two months with cortisone treatment.
