Simultaneous presentation of idiopathic macular and posterior full-thickness retinal holes successfully treated with inverted internal limiting membrane flap technique
Full text linkPurpose: To report an unusual non-iatrogenic case of central macular and posterior full-thickness retinal holes (FTRHs). Observations: A 60-year-old man presented with a progressive visual loss in the right eye. A complete ophthalmological evaluation including best corrected visual acuity (BCVA) measurement, fundus examination and spectral - domain optical coherence tomography (SD–OCT) was performed. Fundus examination and SD-OCT confirmed the presence of simultaneous macular and posterior FTRHs. A 25-gauge vitrectomy was performed and the internal limiting membrane (ILM) was grasped and peeled off around the two holes. A fragment of the peeled-off ILM anchored on the FTRHs edges was left and inserted into the gaps. Closure of both retinal holes was achieved at 1-month, and BCVA improved from 20/630 at baseline to 20/63 at month 3. No intraoperative or postoperative complications were recorded. Conclusions and Importance: Inverted ILM flap technique represents a good treatment option in this rare non-iatrogenic condition, allowing a good anatomical and functional recovery
Bilateral noncalcified astrocytic hamartomas in retinitis pigmentosa: Multimodal imaging evaluation over 8 years of follow-up
No full textPurpose: To report the evolution of optic disk noncalcified astrocytic hamartomas in a patient with retinitis pigmentosa throughout 8 years of follow-up. Methods: Case report. Results: A 42-year-old white man with a diagnosis of retinitis pigmentosa was referred to our medical retinal center for the first time in 2010, for the development of a new optic nerve head lesion in the right eye. Fundus examination, fundus autofluorescence, fluorescein and green indocyanine angiography, spectral-domain optical coherence tomography were performed and confirmed the presence of a papillary noncalcified astrocytic hamartoma in the right eye. Four years later, multimodal imaging evaluation revealed in the left eye the presence of a first optic disk benign tumor, and in 2018, a second in the nasal retina, while in the right eye the sole papillary lesion increased slightly in size. Conclusions: Noncalcified astrocytic hamartomas can occur in patients with retinitis pigmentosa and can increase in size and number in time. A complete multimodal imaging evaluation is necessary to identify and classify any kind of new lesion that, as known, are associated with these group of hereditary retinal degenerations
OCT angiography characteristics in patients with chronic CSCR complicated with polypoidal choroidal vasculopathy
No full textManagement of Accidental Intravitreal Dexamethasone Injection Into the Lens: A Case Report.
Full text linkAn accidental injection of a dexamethasone implant inside the crystalline lens was observed in the right eye of a 63-year-old woman suffering from a macular edema secondary to a central retinal vein occlusion. A 23-gauge pars plana vitrectomy and lensectomy followed by an intraocular lens implantation were performed to carefully remove the lens and save the whole implant in order to preserve its therapeutics effects. A strict follow-up over the following 3 months revealed an improving of macular edema and no postoperative complications. The injection of a dexamethasone implant into the lens could be effectively and successfully managed with a pars plana vitrectomy and lensectomy
Choroidal neovascularization in caucasian patients with longstanding central serous chorioretinopathy
No full textPurpose:
To report the frequency of choroidal neovascularization (CNV) in Caucasian patients with chronic central serous chorioretinopathy (CSC).
Methods:
Retrospective consecutive series of 272 eyes (136 patients) who were diagnosed as having chronic CSC based on clinical and multimodal fundus imaging findings and documented disease activity for at least 6 months. The CNVs were mainly determined by indocyanine-green angiography.
Results:
Patients were evaluated and followed for a maximum of 6 years, with an average follow-up of 14 ± 12 months. Distinct CNV was identified in 41 eyes (34 patients). Based on fluorescein angiography, 37 eyes showed occult with no classic CNV, 3 eyes showed predominantly classic and 1 eye had a disciform CNV. Furthermore, indocyanine-green angiography revealed polypoidal choroidal vasculopathy lesions, in 27 of the 37 eyes, classified as occult CNV on fluorescein angiography. In total, 17.6% of our patients with chronic CSC were found to have CNV that upon indocyanine-green angiography were recognized as being polypoidal choroidal vasculopathy.
Conclusion:
In our series of Caucasian patients, we found a significant correlation between chronic CSC and CNV, in which the majority of patients with CNV were found to have polypoidal choroidal vasculopathy. Our findings suggest that indocyanine-green angiography is an indispensable tool in the investigation of chronic CSC
Endothelial cell density change in fully dislocated XEN Gel IMPLANT after trabeculectomy: A case report
No full textPurpose: To report a case of fully dislocated XEN Gel Implant device into the anterior chamber, 18 months after its implantation and its impact on endothelial cell density. Result: A 75-year-old man with a history of multiple glaucoma surgeries during the last three years presented with an entirely dislocated XEN Gel implant into the anterior chamber. An endothelial cell density reduction was observed over 18 months. Thus, the implant was removed. In the short-term after surgery, the endothelial cell loss rate reduced. Conclusion: XEN Gel Implant can dislocate into the anterior chamber, increasing endothelial cell loss in an eye already underwent multiple surgical procedures with subsequent adverse events. Therefore, if the implant seems displaced, the endothelial cell density should be monitored, and the length of the free-tube segment within the anterior chamber should be measured, during the patient’s follow-up
