Microsoft Excel was used for Descriptive statistics of data obtained, while IBM SPSS&nbsp; Version 25.0 software was used for the Cronbach Alpha test for reliability of the modified questionnaire and Chi-square test to determine the relationship between gender and awareness of scleral contact lens practice.</p> <p><strong>Results</strong>: A total of 307 of the 310 responses were included in the study. 3 of the responses were excluded because they were not properly&nbsp; filled. The mean ± standard deviation (SD) of years of practice was 11.2 ± 8.4 years and the contact lens fitting experience was&nbsp; 7.3 ± 6.9 years. Most optometrists surveyed worked in private practice (60.3%, n=185) or hospital-based settings (30.6%, n=94). The&nbsp; majority of optometrists (94.1%, n=289) reported they were aware of scleral contact lenses and only a small portion (5.9%, n=18) had not&nbsp; heard of it. There was no significant relationship between gender and awareness of scleral contact lens (p=0.422). Out of the 307&nbsp; responses received, only 44 (14.3%) optometrists indicated that they fit scleral contact lenses. The most frequent condition for which&nbsp; scleral contact lenses were prescribed included Keratoconus (n=33, 75%) and the least condition was Presbyopia (n=1, 2.3%). However,&nbsp; majority of optometrists (n=263, 85.7%) reported scleral contact lenses were not fitted in their practice, the most frequent reason being&nbsp; the unavailability and cost of scleral contact lenses (n=177, 67.3%), followed by negative assumptions and attitudes of patients towards&nbsp; contact lens wear (n=107, 40.7%).</p> <p><strong>Conclusion</strong>: The level of awareness of scleral contact lenses among optometrists in Nigeria is high; however, there is a limited practice of scleral contact lens fitting in Nigeria which could be as a result of the unavailability and cost of&nbsp; these lenses.&nbsp;</p> Ngozi N.

The study began by instructing participants to refrain from using smartphones for 60 minutes. Baseline&nbsp; measurements for tear quantity and tear quality were obtained through Schirmer and invasive tear breakup time test respectively.&nbsp; Subsequently, participants were asked to read an article on a smartphone for 60 minutes, followed by the same tear tests.</p> <p><strong>Results</strong>: Statistical analysis, using paired t-tests, revealed a statistically significant decrease (p &lt;0.05) in tear quantity after smartphone&nbsp; use: right eye (RE) from 17.08 ± 3.01mm to 14.71 ± 2.63mm and left eye (LE) from 17.01 ± 2.63mm to 14.91 ± 2.47mm. Tear quality also&nbsp; showed a statistically significant decline (p&lt;0.05) after smartphone use: RE from 16.17 ± 2.90 secs to 14.26 ± 2.67 secs and LE from 16.17 ±&nbsp; 2.74 secs to 14.46 ± 2.67 secs.</p> <p><strong>Conclusion</strong>: Smartphone use was found to lead to reduced tear quantity and tear quality among University&nbsp;&nbsp; of Benin students.</p> Faustina K.

The aim of this study was to identify bacterial isolates from hydrogel (soft)&nbsp; contact lenses worn by selected students of the University of Benin, Nigeria, using 16S rRNA gene analysis.</p> <p><strong>Methods</strong>: Eleven bacterial&nbsp; isolates from the worn hydrogel lenses, which remained unidentified with the traditional phenotypic techniques, were transferred to the&nbsp; molecular biology section of the Labor Medical and Research Laboratory for possible identification by phylogenetic analysis, to have a full&nbsp; range of bacteria considered as normal flora of the eyes. Bacterial genomic DNA was extracted with the ZymoBIOMICS DNA Mini Kit&nbsp; (Zymo Research Corp., Irvin, CA, USA), amplified with polymerase chain reaction (PCR), and the amplicons were sequenced with the&nbsp; ABI3500xL Genetic Analyzer (Applied Biosystems, Foster City, CA, USA). The nucleotide sequences were assembled and deposited in the&nbsp; GenBank database for alignment with the prototype strains.</p> <p><strong>Results</strong>: The bacterial isolates identified were Burkholderia cenocepacia&nbsp; GIMC 4560: BCN122, <em>Cupriavidus pauculus</em> KPS 201, and Comamonas testosteroni M.pstv. 4.2, <em>Acinetobacter calcoaceticus</em> NBRC 13006,&nbsp; Achromobacter denitrificans SW2, <em>Bacillus cereus</em> FORC_048, <em>Staphylococcus saprophyticus</em> Marseille-P541, <em>Burkholderia cenocepacia</em> GIMC&nbsp; 4560: Bcn122, <em>Acinetobacter calcoaceticus</em> 7.3, and <em>Comamonas sp.</em> 6.1 and Acinetobacter sp. pp2a.</p> <p><strong>Conclusion</strong>: The 16S rRNA gene&nbsp; sequence analysis was able to identify 82% of the isolates at the strain level and 18% at the genus level.&nbsp;</p> E.

Although medical journals shape clinical practice and decision-making, there is a backdrop of&nbsp; perceived reader apathy. Here, we describe the readership of the Journal of the Nigerian Optometric Association (JNOA), investigate the attitudes and perceived barriers towards the JNOA.</p> <p><strong>Methods</strong>: Of the 155 optometrists surveyed, aged 39.0 ± 9.8 years, 13 (8.4%) were&nbsp; researchers/ academics, and majority were women (n=83, 53.5%). Participants’ reading pattern, perception of the articles, suggestions on&nbsp; what could motivate them to read the journal articles were assessed. Chi-square test determined the association between journal&nbsp; readership and individual variables.</p> <p><strong>Results</strong>: Although majority of the participants (90.2%) said their clinical practice was guided by&nbsp; evidence, 53% read a scientific article at least once a month, and only 41% (mostly younger optometrists aged 20-40years) with fewer&nbsp; years of practice experience read the JNOA. Those concerned about the length of the articles (67%, p=0.015) or who felt the articles lacked&nbsp; clinical relevance (75%, p=0.002) were less likely to read JNOA. Presentation format (electronic or hard copies) had no significant&nbsp; effect on readership. Participants felt that providing updates on current clinical practice, and having a continuing professional&nbsp; development (CPD) article in JNOA could encourage readership.</p> <p><strong>Conclusion</strong>: Overall, readership of JNOA was low among members with&nbsp; length of articles and lack of clinical relevance perceived as barriers. Including CPD articles and sections like clinical relevance may&nbsp; improve readership of JNOA.</p> Bernadine Nsa Ekpenyong, Godwin Ovenseri-Ogbomo, Uchechukwu Levi Osuagwu, Augustine Ugochukwu Akujobi, Kindness Charles, Philips Ifeanyichukwu Ebisike, Kelechi Mezu-Nnabue, Udo Ubani, Ikenna Ejinkeonye, Ogechi Nwokedi, Eki Oghre, Nwakaego Ikoro Copyright (c) 2024 https://www.ajol.info/index.php/jnoa/article/view/275117 Mon, 29 Jul 2024 00:00:00 +0000 New Trends in Neuro-protection in Glaucoma https://www.ajol.info/index.php/jnoa/article/view/275118 <p>Recent advancements in neuroprotection for glaucoma have seen a shift towards multifaceted approaches targeting various aspects of&nbsp; the disease's pathophysiology. Traditional strategies were primarily focused on lowering intraocular pressure (IOP) but emerging trends&nbsp; highlight the importance of preserving retinal ganglion cells (RGCs) and their axons. Novel therapeutics aim to enhance neurotrophic&nbsp; support, reduce excitotoxicity, and mitigate oxidative stress, complementing IOP-lowering therapies for comprehensive management.&nbsp; Stem cell therapies, neurotrophic factors, and gene therapies show promise in promoting RGC survival and axonal regeneration.&nbsp; Additionally, the repurposing of existing drugs, such as calcium channel blockers and anti-inflammatory agents, for neuro-protection in&nbsp; glaucoma underscores the importance of exploring diverse mechanisms. These innovative approaches represent a paradigm shift in&nbsp; glaucoma management, emphasizing the need for a holistic approach targeting both IOP and neuroprotection to preserve vision&nbsp; effectively.</p> Andrew U. Omaka , Amarachi Ezeigbo Copyright (c) 2024 https://www.ajol.info/index.php/jnoa/article/view/275118 Mon, 29 Jul 2024 00:00:00 +0000 Case report on scleral lens management of corneal irregularity secondary to oculocutaneous Albinism https://www.ajol.info/index.php/jnoa/article/view/275119 <p>The purpose of this case report is to show the benefits of scleral lenses in the management of corneal irregularity and primary corneal&nbsp; ectasia. Scleral lenses are special corneal gas permeable lenses designed with a larger diameter to rest on the conjunctiva and vault over&nbsp; the cornea. This way, the lenses replace the damaged cornea with a smooth, uniform, regular surface that corrects the visual distortions&nbsp; caused by an irregular cornea. Scleral lenses provide optimization of vision with additional benefits of protection and continuous&nbsp; hydration of the ocular surface through the post-lens tear reservoir. In Nigeria, scleral lenses are a new line of treatment that is rapidly&nbsp; becoming a valuable treatment option in the management of irregular astigmatism, corneal irregularity, and ocular surface diseases like&nbsp; keratoconus, keratoglobus, and pellucid marginal degeneration. This is a case of a teenage Nigerian girl with oculocutaneous albinism,&nbsp;&nbsp; nystagmus, and irregular astigmatism.</p> John Samssedi Copyright (c) 2024 https://www.ajol.info/index.php/jnoa/article/view/275119 Mon, 29 Jul 2024 00:00:00 +0000 Editor’s Perspectives https://www.ajol.info/index.php/jnoa/article/view/275112 <p>No Abstract</p> Nwakaego Ikoro Copyright (c) 2024 https://www.ajol.info/index.php/jnoa/article/view/275112 Mon, 29 Jul 2024 00:00:00 +0000 Current and future impacts of climate change in eye and vision health https://www.ajol.info/index.php/jnoa/article/view/275113 <p>No Abstract</p> Obialo Iwunze Osigwe Copyright (c) 2024 https://www.ajol.info/index.php/jnoa/article/view/275113 Mon, 29 Jul 2024 00:00:00 +0000
