MENNEL, S; CALLIZO, J; MEYER, CH  and  KROLL, P. Subjetive decrease of visual acuity after photodynamnic therapy: documentation by optical coherence tomography and its correlation with visual acuity. Arch Soc Esp Oftalmol [online]. 2005, vol.80, n.7, pp.413-416. ISSN 0365-6691.

Case report: A 68-year-old patient complained of decreased visual acuity (VA) two days after photodynamic therapy (PDT) had been performed. VA decreased from the pre-operative value of 0.4 to 0.1 on the second postoperative day. With additional + 1.75 diopters, VA was 0.32. Optical coherence tomography (OCT) disclosed a subneuroretinal fluid accumulation causing a serous retinal detachment 600 µm in height. One week postoperatively, neither decreased vision nor retinal elevation were noted. Discussion: The temporary subjective decreased VA could be predominantly reduced by adequate refraction. OCT and VA measurements excluded ischemia of the neuroretina or the choroid as a causative factor.
