SD-OCT showing diffuse DME with subretinal fluid and intact inter-outer segment layer at baseline. B. 24 months after surgery complete resolution of intra- and subretinal fluid. 2C-D. Patient presenting without biomarkers for good visual outcome, who had late intervention. C. SD-OCT showing diffuse DME without subretinal fluid and damaged inter-outer segment layer at baseline. D.

A more sophisticated and promising technique is based on the PLR to flickering stimulation (fPLR). Our aim was to compare fPLR and pPLR parameters in order to validate fPLR paradigm. Two different experiments were carried out in young participants to compare parameters of chromatic pupillary measurements under flickering and pulsed conditions. We found that the fPLR amplitude parameter was significantly associated with pPLR transient constriction parameter. Also, for some conditions, typical pulse parameters can be identified directly in the fPLR recordings.

There are many tips and tricks shared by many of them despite they are referred to only one. I want to appreciate their kind collaboration with this chapter.

All three patients were treated for exudative age-related macular degeneration and were taking warfarin for chronic anticoagulation. Before photodynamic therapy, the international normalized ratio ranged from 1.2 to 1.6. All three patients had received at least one previous verteporfin treatment in the study eye. All three hemorrhages were not noted immediately after photodynamic therapy and were documented within 1 to 2 weeks following the procedure. Patients with age-related macular degeneration who are receiving warfarin therapy and undergoing repeat verteporfin treatments appear to be at risk for submacular hemorrhages.

Design Multicenter, retrospective, interventional study. Participants 120 eyes from 120 patients with naïve DME treated with PPV and ILM peeling with a follow up of 24 months. Methods Change in baseline best corrected visual acuity (BCVA) and central subfoveal thickness (CST) 1, 6, 12 and 24 months after surgery. Predictive value of baseline BCVA, CST, optical coherence tomography (OCT) features (presence of subretinal fluid (SRF) and photoreceptor damage), and time between DME diagnosis and surgery. Additional treatment for DME
