Item Acute monocular oligemia in a patient with migraine with aura demonstrated using OCT-angiography: A case report.(European Journal of Ophthalmology, 2020) González Martín-Moro, Julio; Porta Etessam, Jesús; Pilo de la Fuente, Belén; Fuentes Vega, Irene; Contreras, InésIntroduction: Migraine is one of the most common causes of transient visual loss. Optical coherence tomography angiography (OCTA) provides fast and non-invasive imaging of the retinal vessels. We report one case of monocular retinal oligemia demonstrated using OCTA during a migraine attack with aura. Case description: A 27-year-old man with a previous history of migraine with visual aura was seen in the emergency room due to acute left hemicranial pain with positive visual symptoms in his right eye. The patient reported a blue stain in his right eye. Optical coherence tomography angiography (OCT-A) showed an extensive area of hypoperfusion in the macular region of his right eye. Forty-eight hours later visual symptoms had improved and the OCT-A showed a significant reduction in the area of hypoperfusion. Seven days later the patient was asymptomatic and retinal perfusion had returned to normal values. Conclusion: Monocular involvement suggests that these retinal vascular changes are independent from cerebral vascular changes, supporting the hypothesis of selective retinal ganglion cell layer spreading depression as the possible cause of some cases of retinal migraine.Item Influence of Main Ocular Variables in #TheDress Perception: An Ophthalmic Survey.(Perception, 2021) González Martín-Moro, Julio; Contreras, Inés; Fuentes Vega, Irene; Prieto Garrido, Francisco; Castro Rebollo, María; González Manrique, Mar; Gómez Sanz, Fernando; Zamora, JavierThe objective of this study is to study the influence of ocular variables in the perception of #thedress and to develop a logistic regression model that could help predict it. This is a cross-sectional study on 1,100 subjects. People who did not report one of the two main perceptions were excluded from the study. Dress perception was codified as 0 (white&gold) or 1 (black&blue). The association between dress perception and demographic and main ocular variables (age, gender, binocular visual acuity, grade of nuclear cataract, crystalline lens status [phakic/pseudophakic], spherical equivalent, and ocular health status) was tested using logistic regression. Receiver operation curves were used to test the predictive value of the model. Several variables were found to be related with dress perception. The best model included three variables—Age: adjusted odds ratio (OR) = 1.02 (1.01–1.03), p = 0.08; ocular refraction: adjusted OR = 1.07 (1.02–1.12), p = 0.009; and nuclear cataract grade: adjusted OR = 1.45 (1.05–1.99), p = 0.026. The predictive value of the model was low (area under the curve = 0.62). Older age, nuclear cataract grade, and hyperopia were associated with black&blue perception. The predictive capacity of the developed model was poor. Only a small proportion of the variability in the #thedress perception can be explained by ocular examination.Item Response to the effect of pharmacologic treatment of migraine on retinal vasculature.(European Journal of Ophthalmology, 2021) González Martín-Moro, Julio; Porta Etessam, Jesús; Pilo de la Fuente, Belén; Fuentes Vega, Irene; Contreras, Inés
