PURPOSE: To investigate potential risk factors for the progression of myopia. METHODS: Prospective study. Myopic progression was evaluated by cycloplegic autorefraction and axial length (AL) every 6 months in children 6 to 15 years old. Univariate analysis and multiple logistic regression were applied. RESULTS: Around 82 children with median age of 10.3±2.3 years. Myopia progressed by -0.816±0.6 D over 18 months. Increased myopic spherical equivalent refraction (SER) was correlated with increase in AL (P<0.001). Univariate analysis found SER to be significantly associated with: age, especially between 6 and 9.4 years old (P=0.001), parental myopia (P=0.028), and less time spent outdoors (P=0.009). There was a significantly greater increase in SER during months with the least daylight hours (P<0.001). CONCLUSION: Outdoor activities and daylight have a protective effect against increased AL and progression of myopia. Younger children with significant myopia should be monitored closely, especially those around 6 years old with myopic parents.

CASO CLÍNICO: Se describe un caso de maculopatía por popper. DISCUSIÓN: Popper es una droga compuesta por varias formas de nitritos de alquilo. Un varón de 39 años, consumidor de popper durante años, acude a la consulta por fosfenos, pérdida de agudeza visual y un escotoma central. El SD-OCT en el ojo derecho presenta pérdida de continuidad a nivel de la línea SI/SE. El SD-OCT del ojo izquierdo muestra un agujero macular externo de aspecto rectangular y con bordes rectos, y un quiste macular externo
CASE REPORT: A case of maculopathy due to «poppers» is described. DISCUSSION: Poppers is a drug composed of various forms of alkyl nitrite. A 39 year-old man, who had been using poppers for years, was seen in the clinic with phosphenes, reduced visual acuity and central scotoma. The SD-OCT in the right eye showed disruption at the level of the IS/OS junction line. The SD-OCT scan in the left eye showed an outer rectangular retinal hole and an outer retinal

We describe the case of a 70-year-old male patient with ethmoid sinus adenocarcinoma who developed an exudative retinal detachment (ERD) in the right eye as the first manifestation. Two weeks after presentation, total regression of the ERD was noted. Extensive investigations for local causes of ERD were unrewarding. Finally, we performed a computed tomography scanning of the head that revealed an ethmoidal mass extending to the orbit. The diagnosis of adenocarcinoma was confirmed by biopsy. Neoplastic phenomena should be considered in patients presenting with temporary ERD.
