[Antiretinal antibodies associated with cystoid macular edema].

Abstract

AIM:

Recently, anti-Enolase and anti-carbonic anhydrase antibodies have been observed in over 60% of patients with retinitis pigmentosa (RP) and cystoid macular oedema (CME). We investigated the presence of these antibodies in a series of patients with CME due to different pathologies.

METHODS:

In 10 patients with CME serum antibodies against Carbonic anhydrase (CA) II (30 kD) and Enolase (46 kD) were sought using Western Blots, Dot Blots as well as ELISA.

RESULTS:

Western and dot blotting showed anti-CA II antibodies in all and anti-Enolase antibodies in six of the 10 patients. The average titer measured with ELISA was 0.9 +/- 0.08 OD Units (0.35-1.4) with a dilution of 1:400.

CONCLUSION:

The presence of anti-retinal antibodies in the serum of all patients confirms the high prevalence of these antibodies in patients with CME. This may suggest that a dysfunction of CA and enolase activity in the retinal pigment epithelium may lie at the root of oedema formation, whereas other mechanisms may be responsible in the absence of these antibodies.
