ABSTRACT

Objectives: To identify risk factors for loss to follow-up in periodic intravitreal anti-vascular endothelial growth factor injections for the treatment patients with diabetic macular edema, subretinal neovascularization, age-related macular degeneration, and retinal vein occlusion in a single eye center in São Paulo, Brazil. Methods: This was a retrospective longitudinal study that gathered information from 992 patients who required intravitreal anti-vascular endothelial growth factor drugs over 6 months. The authors included age, eye disease, laterality, monthly income, distance, and payment mode as risk factors. Results: Two hundred and seventy patients (29.93%) were lost to follow-up. Multivariate analysis showed age, monthly income, eye involvement, and type of medical assistance independently associated with loss to follow-up. The odds of loss to follow-up were greater among older patients than those less than 50 years (reference), p < 0.001. The odds of loss to follow-up were greater among patients who received unilateral treatment than those who received bilateral injections (p = 0.013). Concerning gross monthly income, there were no differences in the odds of the four salary strata; the data also indicate an absence of difference in the three strata of patients' distance to the clinic. Considering the diagnosis, only age-related macular degeneration showed greater odds of loss to follow-up (p = 0.016). Finally, the data suggest greater odds of loss to follow-up in private patients than in those on a health care plan (p < 0.001). Conclusion: Loss to follow-up is paramount because many patients may remain unassisted concerning their eye diseases. Identifying the risk factors is crucial to enforcing measures to increase adherence and the long-term success of the treatment.

ABSTRACT

A síndrome ocular isquêmica (SOI) ocorre devido à hipoperfusão ocular crônica secundária à obstrução da artéria carótida. O quadro clínico inclui, entre outros, retinopatia proliferativa similar a retinopatia diabética. A SOI deve ser considerada principalmente nas retinopatias proliferativas unilaterais ou muito assimétricas e nos casos refratários ao tratamento por fotocoagulação. A indicação da endarterectomia nos pacientes com SOI isolada não é bem definida. Este trabalho relata uma paciente com SOI simulando retinopatia diabética proliferativa unilateral e tratada por endarterectomia.


Ischemic ocular syndrome (IOS) is caused by stenosis of carotid artery. Proliferative retinopathy is one of the signs and can lead to misdiagnosis with diabetic retinopathy. IOS must be considered in case of proliferative retinopathy asymmetric and refractory to laser treatment. Carotid endarterectomy in patients with IOS with no neurologic manifestations remains controversy. This paper reported a patient with IOS simulating diabetic retinopathy and treated with endarterectomy.
