Multimodal Imaging Study of Patients With Vitamin A Deficiency Retinopathy.

OBJECTIVES: To describe multimodal imaging findings of vitamin A deficiency retinopathy. METHODS: A retrospective study of patients with serum retinol < 0.3 mg/L. Fundus color photos, spectral domain-optical coherence tomography (SD-OCT), and fundus autofluorescence (FAF) were reviewed and, when available, electrophysiological tests were analyzed. RESULTS: Forty-five eyes (63.9 ± 15.7 years) were included. Ultra-widefield fundus photography showed drusen-like deposits (53.3%) and macular retinal pigment epithelium (RPE) mottling (40%). The deposits were hypoautofluorescent, and a perifoveal hyperautofluorescent ring was present in 8.9%. By SD-OCT, the ellipsoid zone had an irregular appearance (100%) and conical deposits anterior to the RPE (33.3%). Electroretinogram (ERG) (66.7%) showed a decrease in b-wave in the scotopic registers, and microperimetry (4.4%) showed decreased foveal sensitivity. After vitamin A supplementation, SD-OCT and FAF showed resolution of all findings. Forty percent of eyes had restoration of the scotopic registers in ERG and improved macular sensitivity by microperimetry (4.4%). CONCLUSIONS: Vitamin A deficiency causes a mild cone dysfunction in addition to the more severe absent rod response. [Ophthalmic Surg Lasers Imaging Retina 2023;54:330-336.].

Idiopathic multifocal choroiditis (MFC): aggressive and prolonged therapy with multiple immunosuppressive agents is needed to halt the progression of active disease. An offbeat review and a case series.

BACKGROUND AND PURPOSE: Idiopathic multifocal choroiditis (MFC) is part of the group of choriocapillaritis entities. The clinical definition of the disease has evolved with time. The aim of this article was to undertake a review on MFC, on its present-day appraisal and nomenclature and we also report a series of patients with emphasis on the clinical presentation and the importance of vigorous immunosuppressive management. METHODS: A review of the literature and a retrospective case series study which was performed in the Centre for Ophthalmic Specialised care (COS), Lausanne, Switzerland. Patients diagnosed from 1994 to 2020 with idiopathic multifocal choroiditis (MFC) treated with multiple immunosuppressants were included. Exclusion criteria were insufficient follow up and cases not treated with vigorous immunosuppressive therapy. Imaging analysis included spectral domain optical coherence tomography (SD-OCT) / enhanced depth imaging OCT (EDI-OCT), OCT angiography (OCT-A). Fluorescein and Indocyanine angiography (FA, ICGA) before and after the instauration of treatment. Best corrected visual acuity (BCVA), intraocular pressure (IOP), routine ocular examination, laser flare photometry (LFP) were performed at presentation and follow-up. Immunosuppression comprised at minimum two among the following agents: prednisone, cyclosporine, azathioprine, mycophenolic acid or infliximab. Mean duration of therapy was calculated. RESULTS: 26 (52 eyes) of 2102 new patients (1.24%) were diagnosed with MFC. 25 (96%) patients were female and 1 (4%) was male. 43/52 (82%) eyes were myopic with a mean dioptre of - 5.87 ± 2.94, six (12%) eyes were hypermetropic with mean dioptres 2.0 ± 2.68 and three (6%) were emmetropic. 14/52 (27%) eyes had at least 1 anti-VEGF injection because of choroidal neovascularisation (CNVs), 1 eye had a phototherapy laser and 37/52 (71%) had no complication of CNVs during the follow-up. 5/26 (19%) fulfilled the inclusion criteria for our study. Mean age was 26.4 ± 9.3 years. Snellen best corrected visual acuity (BCVA) at presentation was 0.955+/-0.26. Mean follow up was 84+/-55 months. LFP at presentation was 6.34 ± 2.94 ph/ms. None of four patients with prolonged treatment and prolonged follow-up showed disease activity. One patient still under therapy after 4 months' follow-up still showed an active neovascular membrane. CONCLUSION: Treatment with multiple immunosuppressive agents was shown to stop the progression of the disease.

Biologic Therapy in Inflammatory Eye Conditions (Ophtalmology): Safety Profile.

Non-infectious uveitis can be a potentially sight threatening disease. Very recently, therapeutic strategies have turned towards a new methodology, which includes biologic agents. The introduction of biologic drugs has started a Copernican revolution in ophthalmology: biologic therapies represent a revolutionary option for those patients who present non-responder, sight threatening uveitis. The availability of these therapies has improved the uveitis outcome. The present review shows the most relevant medical literature on biologic agents in ophthalmology, such as tumor necrosis factor blockers, anti-interleukins and other related biologics. Several papers reported the efficacy of biologic agents in a large number of refractory uveitides, which suggest a promising role of biologic drugs for selected cases. On the other hand, the medical literature does not have consistent numbers yet, which hopefully will validate the promising preliminary results. Biologic agents are not only promising drugs for the treatment of nonresponder uveitis, but also they show an apparently favourable safety profile, although several topics remain unsolved: it is still not clear when commencing the treatment, which agent to choose, and the length of biologic therapy. Moreover, the high costs and the still not clear safety profile have very often limited their use only for severe, non-responder uveitis in highly specialized uveitis centres.

Long-term control of non-infectious paediatric panuveitis refractory to traditional immunesuppressive therapy, successfully treated with Adalimumab (HumiraTM).

OBJECTIVES: The aim of this paper is to present two cases of severe idiopathic non-infectious paediatric panuveitis, unresponsive to traditional therapy, successfully treated with Adalimumab (HumiraTM, Abbott Pharmaceutical Inc.) in the long term. METHODS: The data of the two cases are presented and the literature is reviewed. RESULTS: At base line, case 1 had 0.2 in the RE and 0.5 in the LE, while case 2 had 0.5 and 0.4 in the RE and LE, respectively. The anterior chamber (AC) of case 1 had 3+ cells and 3+ flare in both eyes, as well as diffuse keratic precipitates (Kps). Case 2 presented 2+ cells and 3+ flare in both eyes, as well as tiny Kps in the inferior part of the endothelium. The Binocular Indirect Ophthalmoscopy (BIO) score was +2 in both eyes of case 1 and case 2 at first examination. After Adalimumab initiation, both patients presented a dramatic resolution of the ocular inflammation, as well as a rapid improvement of the BCVA. Case 1 had 0.8 and 1.0 in the RE and the LE, respectively, while case 2 presented 1.0 in both eyes. At the last visit, both patients presented a quiet uveitis and stable BCVA: case 1 had 0.8 and 1.0 in the RE and the LE, respectively, while case 2 presented 1.0 in both eyes. No side effects were recorded during this time. CONCLUSIONS: Adalimumab can be a promising drug for the therapy of severe, refractory paediatric uveitis, although further studies are needed on its application in uveitis.

Management of chronic anterior uveitis relapses: efficacy of oral phospholipidic curcumin treatment. Long-term follow-up.

Curcumin has been successfully applied to treat inflammatory conditions in experimental research and in clinical trials. The purpose of our study is to evaluate the efficacy of an adjunctive-to-traditional treatment with Norflo tablets (curcumin-phosphatidylcholine complex; Meriva) administered twice a day in recurrent anterior uveitis of different etiologies. The study group consisted of 106 patients who completed a 12-month follow-up therapeutic period. We divided the patients into three main groups of different uveitis origin: group 1 (autoimmune uveitis), group 2 (herpetic uveitis), and group 3 (different etiologies of uveitis). The primary end point of our work was the evaluation of relapse frequency in all treated patients, before and after Norflo treatment, followed by the number of relapses in the three etiological groups. Wilcoxon signed-rank test showed a P < 0.001 in all groups. The secondary end points were the evaluation of relapse severity and of the overall quality of life. The results showed that Norflo was well tolerated and could reduce eye discomfort symptoms and signs after a few weeks of treatment in more than 80% of patients. In conclusion, our study is the first to report the potential therapeutic role of curcumin and its efficacy in eye relapsing diseases, such as anterior uveitis, and points out other promising curcumin-related benefits in eye inflammatory and degenerative conditions, such as dry eye, maculopathy, glaucoma, and diabetic retinopathy.

Association of systemic steroids and mycophenolate mofetil as rescue therapy for uveitic choroidal neovascularization unresponsive to the traditional immunosuppressants: interventional case series.

To study the efficacy of systemic steroids (SS) associated with mycophenolate mofetil (MMF) for the control of juxta/sub-foveal uveitic choroidal neovascularization (CNV) unresponsive to the traditional immunosuppressive agents. Patients with juxta/sub-foveal uveitic CNV unresponsive to the traditional immunosuppressive drugs were treated with SS and MMF. The study was designed as a prospective, consecutive, open-label, interventional case series. Visual gain and loss were defined as improving or worsening of two or more lines of best-corrected visual acuity (BCVA), respectively. CNV size outcome was dichotomized as "increased" or "stable/reduced", if increased >200 µm(2), or reduced ≥ 200 µm(2) or not modified by 200 µm(2), respectively. Nine cases (12 eyes) have been considered; ages ranged from 27 to 56 years. The mean follow-up time was 18.2 ± 2.9 months (min: 14 months, max: 23 months). At base-line, the mean BCVA was 0.3 ± 0.17, improving up to 0.57 ± 0.25 and to 0.63 ± 0.22 (P < 0.001, paired t-test) at the 6 and 12-month follow-ups, respectively. At the last follow-up, all the patients had stable/improved BCVA (P < 0.0001, Fisher's exact test) and stable/reduced lesion size (P < 0.0001, Fisher's exact test). None of the patients complained of any severe adverse event during the treatment. The combination of SS and MMF seems to be a promising strategy in order to control uveitic CNVs unresponsive to the traditional immunosuppressive agents. Further studies are needed to validate the data of this case series.
