    PURPOSE. To describe the efficacy of MP-1 in detecting early multiple sclerosis (MS) retinal lesions and in monitoring the effectiveness of treatment in terms of changes in macular sensitivity. METHODS. A 21-year-old woman with MS was referred to us complaining of recurrent episodes of eyesight loss in both eyes. At ophthalmologic examination, best-corrected visual acuity was 20/25 bilaterally; ophthalmoscopy showed bilateral slight optic neuritis without swelling of the disc. Static perimetry of central visual field (30 degrees, by Octopus 101, Haag-Streit AG, Switzerland) and retinal sensitivity of the 12 central degrees (by MP-1 Micro Perimeter, Nidek Inc., Italy) were performed on the patient at that time. The microperimeter (MP-1) showed a loss of sensitivity in the macular region with 0.28 +/- 0.9 dB sensitivity in the right eye and 19.42 +/- 1.5 dB in the left. The mean fixation stability was 91 % considering 20 and 99% considering 4 degrees around the fixation points in the right eye, and 97% in 2 degrees and 100% in 4 degrees central degrees in the left. In the weeks that followed vision continued to get worse in both eyes, so she underwent a steroid therapy with methylprednisolone IV 1000 mg/day for 5 days and 500 mg/day for 3 days. RESULTS. After 8 days of therapy the MP-1 showed a significant recovery in the right eye, with mean light sensitivity being 19.61 +/- 1.3 dB in the right eye and 20.0 +/- 0 dB in the left eye in both macular and peripapillary regions. The mean fixation stability was 100% considering 2 degrees and 100% considering 4 degrees around the fixation points in both eyes. CONLCUSIONs. The MP-1 can be an interesting tool for neuro-ophthalmologists as it allows a more precise evaluation of the macular and peripapillary region, which is not easily studied with conventional automated perimetry. In MS, the presence of a subclinical form of optic nerve involvement can be demonstrated in a very early stage, and well followed by the introduction of microperimeter testing in the standard examination protocol

    Perfluorocarbon liquid assisted large retinal epithelium patching in sub-macular hemorrhage secondary to age related macular degeneration

    We investigate the safety and feasibility of large retinal pigmentary epithelium (RPE)-Choroid-free graft after surgical drainage of massive sub-macular hemorrhage (SMH) due to age-related macular degeneration (ARMD). Four previously untreated patients (three females and one male) underwent to three port pars plana vitrectomy, induction of retinal detachment and peripheral temporal 180A degrees retinotomy. The retina was then folded nasally, to allow access for removal of sub-macular Hg and CNV complex. A full-thickness-large autologus Chorio-RPE patch was grafted. Silicone oil was used as endotemponade for approximately 12 weeks. After removal of silicone oil, the patients were followed-up for 6 months. SMH was completely removed in all cases. It was possible to graft a large RPE patch safely that is sufficiently large to cover the entire defect of macular RPE. At last follow-up, improvement in visual acuity (from 3 +/- 0.9 to 55 +/- 9 ETDRS letters) and recovery of central fixation was observed in all patients. Our surgical technique for large elevated SMH seems to be feasible and efficacious approach to harvest and relocate large RPE patch and to save limited vision in selected patients

    Bilateral ischemic maculopathy in a patient with AIDS

    PURPOSE. To describe ischemic maculopathy as a cause of sudden bilateral decreased vision in a patient with human immunodeficiency virus (HIV) infection. METHODS. A 44-year-old HIV-positive woman presented with bilateral decreased vision and normal examination, except for pale maculae and retinal vascular tortuosity. Fluorescein angiography showed bilateral enlargement of the foveal avascular zone with perifoveal dye leakage. CONCLUSIONS. Ischemic maculopathy is a potential cause of decreased vision in patients with acquired immunodeficiency syndrome, even in patients with immune sustained recovery. This condition can be almost totally reversible, in the absence of other concomitant ocular pathologies
