Optociliary veins and central retinal vein occlusion.
1993
In a follow up of 94 patients with central retinal vein occlusion (CRVO) whose onset had taken place less than 1 year earlier, optociliary veins (OCVs) were found in 7.4% at first examination. Among the 79 eyes in which the fundus of the eye was very visible after a follow up of more than 1 year OCVs were found in 30.4%, showing a late development of OCVs in many cases of CRVO. No difference was found in the occurrence of OCVs between non-ischaemic and ischaemic forms of CRVO. The visual acuity of the eyes with CRVO that developed OCVs was not significantly different from the visual acuity of the eyes without OCVs. Thus, the presence of OCVs in CRVO does not seem to be associated with bette…
PHOTODYNAMIC THERAPY WITH VERTEPORFIN FOR CHOROIDAL NEOVASCULARIZATION ASSOCIATED WITH RETINAL PIGMENT EPITHELIAL DETACHMENT IN AGE-RELATED MACULAR D…
2007
Abstract PURPOSE: To assess the effectiveness of photodynamic therapy (PDT) with verteporfin for choroidal neovascularization (CNV) associated with retinal pigment epithelium detachment (PED) in age-related macular degeneration. METHODS: Thirty eyes of 26 patients with CNV and PED were treated with PDT. The eyes were divided in two groups based on CNV location in relation to PED; group 1 included 13 eyes with CNV within PED, and group 2 included 17 eyes with CNV at the edge of PED. The median follow-up was 16 months. RESULTS: Patients received a mean +/- SD of 2.83 +/- 1.26 treatments (range, 1-6 treatments). In the whole cohort, the mean preoperative visual acuity changed from 20/144 (0.86…
Subretinal neovascularization in anterior ischemic optic neuropathy.
1991
A 66-year-old man with typical anterior ischemic optic neuropathy in one eye suffered from edema of the optic disc without functional changes in the fellow eye. However, 7 months later, a reduction in visual acuity, a change in the visual field and a worsening of the contrast-sensitivity curve demonstrated the development of typical anterior ischemic optic neuropathy in this eye as well. After another 6-month period, in addition to these changes, an extensive subretinal neovascular membrane developed in the papillomacular area, which further reduced the patient's visual acuity and required treatment with laser photocoagulation. To our knowledge, this is the first case report of the occurren…
Polypoidal choroidal vasculopathy in pachychoroid: combined treatment with photodynamic therapy and aflibercept
2022
Abstract Introduction To evaluate the effects of combined therapy using intravitreal Aflibercept (IVA) and photodynamic therapy (PDT) on polypoidal choroidal vasculopathy related to pachychoroid disease (PPCV).Methods Patients with PPCV were treated with PDT combined with 3 IVA injections on a monthly basis, followed by pro re nata criteria. The 12-month follow-up consisted of multiple revaluations of visual acuity and SSOCT parameters of clinical activity.Results Nineteen eyes were included in the study; mean age was 65.5 years. Visual acuity improved after 12 months (0.35 ± 0.25 to 0.2 ± 0.20 logMAR, p = 0.005). Percentage of eyes with intraretinal and subretinal fluid reduced from baseli…

Delayed Suprachoroidal Hemorrhage After Pars Plana Vitrectomy: Five-Year Results of a Retrospective Multicenter Cohort Study
2015
Purpose To determine the incidence, risk factors, and outcomes of delayed suprachoroidal hemorrhage after vitrectomy. Design Retrospective multicenter cohort study. Methods All consecutive patients who underwent primary vitrectomy, from January 2009 to December 2014, at 4 tertiary vitreoretinal centers in Italy were enrolled. Patient demographics and systemic, ophthalmic, operative, and postoperative data from all centers were extracted from the electronic record system using standardized data collection forms. All eyes that developed delayed suprachoroidal hemorrhage within 48 hours of the end of the vitrectomy were identified as the delayed suprachoroidal hemorrhage group; all other eyes …
Intravitreal pegaptanib sodium for refractory pseudophakic macular oedema.
2008
Evaluate the efficacy of intravitreal pegaptanib sodium (Macugen®) in refractory pseudophakic cystoid macular oedema (CME). Prospective, nonrandomized, interventional case series. Four eyes of four patients with refractory pseudophakic CME to pars plana vitrectomy and intravitreal bevacizumab and triamcinolone, were treated with pegaptanib sodium, with a mean follow up of 4 months. Pre- and postinfection examinations included assessment of best-corrected visual acuity (BCVA) using the Early Treatment Diabetic Retinopathy Study chart (ETDRS), fluorescein angiography (FA), and optical coherence tomography (OCT). Visual acuity increased in all patients after intravitreal pegaptanib sodium. OCT…
Correlation Between Ischemic Retinal Accidents and Radial Peripapillary Capillaries in the Optic Nerve Using Optical Coherence Tomographic Angiograph…
2017
Background: Perfusion of the optic nerve has been widely studied using fluorescein angiography (FAG), which is currently regarded as the criterion standard. However, FAG has adverse effects associated with intravenous contrast administration and is limited in its capacity to characterize and stratify the different vascular layers of the optic nerve and retina. The use of new imaging techniques, such as optical coherence tomographic angiography (Angio-OCT), is therefore important. Aim: A qualitative description is made of the vascular layers of the optic nerve and of how vascular events affect radial peripapillary capillaries (RPC). Two patients with central retinal artery occlusion (CRAO), …
Serous Detachment of the Retina: A Complication of Branch Retinal Vein Stenosis
2005
The author reports a case of serous detachment of the retina, which has developed in an eye with veno-venous collaterals, secondary to stenosis of a branch of the central retinal vein near the optic disc. This complication has not previously been described in this retinal vascular obstructive disease.
