Astigmatism treatment during phacoemulsification: a review of current surgical strategies and their rationale
(A) Fotografia em lâmpada de fenda do olho direito (OD) evidenciando alterações irianas compatíveis com a síndrome de Cogan-Reese (síndrome ICE), com corectopia/ectrópio uveal e múltiplos nódulos pigmentados na superfície da íris. (B) Fotografia em lâmpada de fenda do olho esquerdo (OS) sem alterações irianas significativas. (C) Microscopia especular do OD mostrando redução da densidade endotelial (2.154 células/mm²), com acentuado pleomorfismo/polimegatismo (baixa hexagonalidade). (D) Microscopia especular do OS com densidade endotelial preservada (2.502,7 células/mm²) e morfologia celular sem alterações relevantes.
