Primary orbital lymphoma is a rare entity comprising of 1-2% of Non‑Hodgkin’s lymphoma, majority of them are B‑cell type. It is a slow growing tumor. It presents in the age group of 50–70 years, with a slight female preponderance. Proptosis is the most common presentation. We, herein, report a case of 48 years old male presenting with right non-axial proptosis, watering of eye, blurring of vision and redness for the last 9 months. After thorough clinical and radiological evaluation, a biopsy was taken for histopathological examination. A primary diagnosis of Lymphoproliferative Disorder was made. Following this, a panel of immunohistochemical markers was applied and a final diagnosis of Non-Hodgkin Lymphoma, B-cell type was given.</p> Nisha Marwah Niti Dalal Manali Satiza Sunita Singh ##submission.copyrightStatement## 2020-11-02 2020-11-02 18 21 10.9734/or/2020/v13i430174 Comparison of Central Corneal Thickness Measurements between Angiovue Optical Coherence Tomography, Ultrasound Pachymetry and Ocular Biometry https://journalor.com/index.php/OR/article/view/30172 <p><strong>Purpose:</strong> To compare central corneal thickness (CCT) measurements and their reproducibility when taken by Ultrasound Pachymetry, Ocular Biometry and Angiovue Optical Coherence Tomography (OCT).</p> <p><strong>Methods: </strong>Twenty-five healthy volunteers were recruited creating a sample size of 50 eyes. All subjects had pachymetric measurements by Ultrasound pachymetry (PachPen Handheld Pachymeter, Keeler Instruments Inc), Ocular biometry (IOL Master 700 Swept Source Biometry, Zeiss) and Angiovue Optical Coherence Tomography (Optovue Avanti RTVue XR Angiovue). The measurements of central corneal thickness for the three devices were taken by the same examiner twice for more accuracy.</p> <p><strong>Results: </strong>The average measurements of central corneal thickness by Ultrasound pachymetry (PachPen Handheld Pachymeter, Keeler Instruments Inc), Ocular biometry (IOL Master 700 Swept Source Biometry, Zeiss) and Angiovue Optical Coherence Tomography (Optovue Avanti RTVue XR Angiovue) were 547.26 μm, 551.36 μm, and 536.42 μm, respectively. The mean standard deviation (SD) of repeated measurements by Ocular biometry was 48.87 μm, which was greater than the mean SD of 44.24 μm and 40.35 μm (P &lt; 0.001) by ultrasound pachymetry and Angiovue optical coherence tomography, respectively. There were statistically significant differences in the measurement results among the 3 methods (Ultrasound pachymetry vs. Ocular biometry P = 0.019; Ultrasound pachymetry vs. Angiovue Optical Coherence Tomography; P &lt; 0.001; Ocular biometry vs. Angiovue Optical Coherence Tomography P &lt; 0.001). There was a significant linear correlation between the Ultrasound pachymetry and Ocular biometry (r = 0.945, P&lt;0.001), Ultrasound pachymetry and Angiovue Optical Coherence Tomography (r = 0.895, P&lt;0.001), and Ocular biometry and Angiovue Optical Coherence Tomography (r = 0.902, P&lt;0.001).</p> <p><strong>Conclusion:</strong> Central corneal thickness readings were comparable between PachPen Handheld Pachymeter, IOL Master 700 Biometry and Angiovue Optical Coherence Tomography; Angiovue optical coherence tomography gave significantly smaller values. The measurements of the 3 methods showed significant linear correlations with one another. All methods provided acceptable repeatability of measurements.</p> E. Pateras A. I.

The information obtained included the patients’ demography, presenting symptoms and signs, research, treatment, outcome, complications and follow-up.</p> <p><strong>Results</strong>: Of the 123 patients with preseptal cellulitis reported on the study, 66 were males and 57 females. In a range of 0 to 80 years old, the mean age was 19 years. The commonest predisposing factor was trauma (20.3%) followed by upper respiratory tract infection (11.4%).&nbsp; Progression to orbital cellulitis was seen in 11.4% of the patients.</p> <p><strong>Conclusion</strong>: Preseptal cellulitis is not uncommon in adults as seen in previous studies. Trauma is now more common than sinusitis as a predisposing factor. Despite oral antibiotic therapy some cases may progress to orbital cellulitis.</p> Akunne I. Apakama Chukwudi C. Uzozie Chinasa A.
