ObjectiveTo explore the linear association between inner retinal layers thickness and macular capillary density compared to variations of global cognition evaluated by psychometric measures in a cohort of Mediterranean subjects aged 65+ years.Materials and methodsWe performed a cross-sectional analysis of 574 participants aged 65 years+ drawn from a population-based Southern Italian study. All subjects underwent neurological evaluations, including global cognitive screening, the Mini-Mental State Examination (MMSE) and frontal assessment battery (FAB), together with an ophthalmic examination including optical coherence tomography (OCT) and OCT-Angiography. We assessed the average thickness of the ganglion cell complex (GCC) and the retinal nerve fiber layer (RNFL), the foveal avascular zone area, and vascular density (VD) of superficial (SVD) and deep (DVD) capillary plexi at the foveal and parafoveal area. Linear regression was applied to assess associations of ocular measurements with MMSE and FAB scores.ResultsIn the linear regression model, foveal DVD (beta = 0.01, 95% CI:0.004–0.052), whole DVD (beta = 0.04, 95% CI:0.02–0.08), and whole SVD (beta = 0.04, 95% CI:0.02–0.07) showed a positive association with MMSE. In addition, foveal SVD (beta = 0.01, 95% CI:0.003–0.05) and whole SVD (beta = 0.03, 95% CI:0.004–0.08) were positively associated with the FAB score. We found no further significant association between the MMSE score or the FAB score and the average thickness of the GCC and RNFL, and FAZ area.ConclusionA direct linear association between the VD of the macular capillary plexi with global and frontal cognitive functions was observed in elderly subjects.
Background Anterior Chamber bleeding without vitreous hemorrhage had been described after the removal of 23G vitrectomy cannulas. We report the case of an anterior chamber bleeding after an intravitreal Dexamethasone implant. Case Report One patient with macular edema due to central retinal vein occlusion in a vitrectomized eye underwent an intravitreal Dexamethasone implant. After the injection the patient suffered from anterior chamber bleeding without signs of vitreous hemorrhage. The complication resolved with a conservative treatment. Conclusion Anterior Chamber bleeding is a possible complication of dexamethasone implant, that can be treated in a conservative way.
Background/Purpose Inverted Inner Limiting Membrane (ILM)-flap approach can fail in the treatment of Optic disc pit maculopathy (ODPM). We report a surgical technique involving human amniotic membrane (hAM) patch implant to treat unresolved ODPM after inverted (ILM)-flap technique. Case Report One patient with decreased visual acuity (1 LogMar) after unsuccessful inverted ILM-flap technique to treat ODPM, underwent hAM patch implant and was evaluated. A surgical approach including a 2 mm size graft patch of hAM implantation over the optic disc pit followed by fluid–air exchange was performed. A gas endotamponade was finally used. The patient was instructed to maintain face-down position for the first three days after surgery. The hAM patch remained detectable over the pit for the entire 6-months follow-up. The ODPM gradually resolved and visual acuity partially recovered to 0.17 LogMar during follow-up. No postoperative complications or recurrence were reported. Conclusion hAM patch implant may be effective to manage ODPM after unsuccessful inverted ILM-flap.
Herein, we report a case of a bilateral orbital floor fracture in a professional cliff diver, with no involvement of the inferior recti, and therefore treated conservatively.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
