SummaryBackgroundHyperlipidemia is an identified factor of premature vessel atherosclerosis. Lipemia retinalis is an unusual retinal manifestation of hyperlipidemia and is thought to be directly correlated with the serum triglyceride level.Case ReportThis paper discusses the case of a 55-year-old patient with lipemia retinalis, which deteriorated his visual acuity. The patient had an extremely high serum cholesterol level (1053 mg/dl) and a very high level of triglycerides (1513 mg/dl). The normalization of serum lipids, reversion of retinal vessels alterations and visual acuity improvement was achieved after an intensive statin lipid-lowering therapy. Pathological changes of the patient’s retina, connected with lipemia retinalis, disappeared completely.ConclusionsHyperlipidemia can cause lipemia retinalis, which is characterized by the hyperlipidemic vascular lesions-whitish color of vessels, lipid infiltration into the retina and decrease of visual acuity. The lipid-lowering therapy may lead to the normalization of the appearance of the fundus and restore the visual acuity.

BaCKground:The aim of the study was to evaluate the vascular flow density measured by optical coherence tomography angiography in patients with retinitis pigmentosa and to compare it with normal subjects. MateriaL and Methods: This was a cross-sectional case control study employing 16 eyes of eight patients with retinitis pigmentosa and 16 eyes of eight healthy subjects. Optical coherence tomography angiography was performed in all subjects. The macula was imaged with a 3 × 3 mm scan, whereas for the optic nerve head, a 4.5 × 4.5 mm scan was taken. Macular and optic disc vascular flow perfusion densities were measured. In addition, the FAZ area was calculated. All data were compared in the two groups. resuLts: The vascular flow perfusion density in the macular and in the optic nerve head was significantly lower in the retinitis pigmentosa group when compared with the control group. On the other hand, the foveal avascular zones area was not significantly different from controls. ConCLusion: Patients with retinitis pigmentosa show a decreased macular and optic nerve head perfusion density compared with healthy subjects

PURPOSE: The study focuses on the problem of self-concept change in patients after radial keratotomy. METHODS: Twenty-five patients (17 female, 8 male) were studied from 6 to 18 months after radial keratotomy using the Adjective Check List by Gough and Heilbrun with the application of double instruction. It concerned self-concept change over a period of observation after surgery, as compared to retrospective (preoperative) self-concept. RESULTS: For current self-concept, patients obtained significantly higher results in the following measures: the number of positive words used for self-description (P < .05); need scales, like affiliation (P < .005), heterosexuality (P < .01), and intraception or insight (P < .05); self-confidence (P < .01); military leadership (P < .05), logical decision making (P < .05); two measures concerning logical-analytical thinking (P < .05). CONCLUSIONS: The results indicate that after radial keratotomy, patients perceived themselves in a more positive way than before surgery, especially as more self-confident in interpersonal functioning.

BaCKground: Optic disc pit (ODP) is a congenital anomaly characterized by indented area of the optic nerve head most likely originating from the incomplete closure of the superior edge of the embryonic fissure. Maculopathy can occasionally complicate this anomaly as intra-retinal and sub-retinal fluid at the macula. In result, maculopathy is associated with a poor visual prognosis due to a serous macular detachment, formation of macular hole, or atrophy of the retinal pigmented epithelium. In this case series, we report of three patients with unilateral ODP. Case report: We attempted to analyze the morphologic changes seen in the ODP and evaluate patients with a complete ophthalmologic evaluation, fundus color photography, spectral-domain optical coherence tomography (SD-OCT) scanning, and magnetic resonance imaging (MRI) of globe and orbit. Magnetic resonance imaging scan was done for optic disc diameter (ODD) and optic nerve sheath diameter (ONSD). ConCLusion: We noticed that in the patient who presented with neurosensory detachment in the macula, the ONSD is larger than in the fellow eye and is larger than the remaining two patients with ODP and without neurosensory detachment of the retina.
