ABSTRACT
This study describe the optical coherence tomography angiography (OCTA) features of a young patient with Tuberous sclerosis complicated with CNV unilateral macular choroidal neovascularization during the ranibizumab therapy. OCTA scans of macular region of right eye, revealed a dense microvascular network confirming the diagnosis of CNV. After four monthly intravitreal injections, OCTA revealed a decrease of size and activity of CNV. OCTA is a valid, non-invasive, dyeless, and reliable method that could improve the diagnosis and management of CNV in child with Tuberous sclerosis.

INTRODUCTION: The aim of this work was to describe the optical coherence tomography (OCT) angiography (OCTA) features in paediatric Leber-Coats disease. METHODS: Three children presenting with unilateral, clinically active Leber-Coats disease were evaluated using spectral domain OCT and OCTA. OCT angiograms were analysed and compared with the current literature. RESULTS: All 3 OCT angiograms showed that the vessels had lost most of their collateral branches and presented many loops. The capillaries were rarefied and anomalies in vessel size, vasodilatation, and macroaneurysms were evident. CONCLUSION: This is the first case series of OCTA performed in children with Leber-Coats disease. OCTA is a non-invasive and non-contact technique, which can be considered of fundamental importance for the diagnosis, clinical management, and follow-up of the disease.

PURPOSE: To compare the mydriatic effects of 2% ibopamine and collyrium containing 10% phenylephrine + 0.5% tropicamide and to study the associated drug in patients with ocular pseudoexfoliation (PEX) syndrome. METHODS: This was a prospective, comparative, interventional clinical study. The study group consisted of 20 patients with ocular PEX syndrome. Intervention procedures included administration of 10% phenylephrine-0.5% tropicamide versus 2% ibopamine versus 2% ibopamine followed by the combination drug. Main outcome measurement was mydriatic efficacy measured in terms of mean pupil diameter. Adverse effects on intraocular pressure (IOP) were measured with a Goldmann applanation tonometer. Mean premedication pupil diameters in all patients were less than 3.5 mm. RESULTS: Instillation of 10% phenylephrine-0.5% tropicamide caused significantly greater mydriasis than 2% ibopamine (pupil diameters: 6.17 mm, SD=1.14 versus 5.33 mm, SD=1.34; p<0.001). Combined use of both collyria significantly increased mydriasis (7.19 mm; SD=0.69) compared with that induced by either of the products alone (p<0.001). Inadequate mydriasis (pupil diameters < 5.5 mm) was observed in 2 patients after administration of 10% phenylephrine-0.5% tropicamide and in 10 following instillation of 2% ibopamine, but the addition of 10% phenylephrine -0.5% tropicamide to ibopamine-treated eyes resulted in adequate dilation in all cases. IOP increases of 4 mmHg over baseline values were observed in 12 (60%) patients after 2% ibopamine. CONCLUSIONS: In patients with ocular PEX, instillation of 2% ibopamine exerts a significant additive effect on mydriasis induced with 10% phenylephrine-0.5% tropicamide with only minimal increases in IOP.
