• BETZABETH VILLALVA -SONIA VALDIZAN
Rolando Rojas Bernuy. MSc (c). OPTOM. FIACLE1, 2
UNIVERSIDAD PERUANA LOS ANDES
INTRODUCCIÓN
• Blebs endotelial o bullas endoteliales
• Rubido (2011). Condición asociada al uso de LC a corto plazo.
• Cambios transitorios en el mosaico endotelial
• Variaciones individuales
• Reportado inicialmente por Zantos y Holden, 1977
• Holden et al. (1985), Williams (1986) y Bonnano y Polse (1987). El
cambio de pH es una posible causa de la respuesta de la ampolla
endotelial.
• Vuelven aparecer por la tarde en UE
