The outcome of the procedure can be affected by several parameters which include patient’s age, optical zone diameter, epithelial hyperplasia, preoperative keratometry as well as astigmatism.<strong> Aim:</strong> This study aimed to determine the relationship between preoperative keratometry and astigmatism with visual recovery time after laser refractive surgery. <strong>Methods:</strong> Records of 174 eyes (174 patients) with myopic astigmatism who had been treated with either LASIK (71 eyes) or PRK (103 eyes) at IIUM Eye Specialist Clinic from January 2015 to June 2018, were retrospectively analyzed. &nbsp;Main outcome measure was the time taken for patients to achieve visual acuity (VA) 6/6 (equivalent to 0.00 LogMAR) postoperatively. Value for keratometry parameter was taken from corneal topography while astigmatism magnitude was taken from manifest refraction. Their correlation with visual recovery time was analyzed using&nbsp;Pearson correlation coefficient (PCC). P &lt;0.05 was considered as statistically significant. <strong>Results: </strong>The mean preoperative astigmatism and mean keratometry was 0.9 ±0.76D and 43.65 ±1.23D respectively. A significant but weak positive correlation between preoperative astigmatism and visual recovery time was observed (P-value = 0.013; R = 0.188), while no correlation observed for mean keratometry (P-value = 0.305; R = 0.078). <strong>Conclusions:</strong> Preoperative astigmatism influenced the visual recovery time post laser refractive surgery in myopic astigmatism patients, but not keratometry.</p> AHMAD NURFAHMI AKHTAR ALI, MD MUZIMAN SYAH MD MUSTAFA, FADZILAH HANIM RAHIM, Nadhirah Ahmad Fauzi, KHAIRIDZAN MOHD KAMAL, MOHD RADZI HILMI Copyright (c) 2020 INTERNATIONAL JOURNAL OF ALLIED HEALTH SCIENCES Tue, 25 Feb 2020 10:53:01 +0800 ASSOCIATION OF NET PTERYGIUM TISSUE MASS (DRY-WEIGHT) IN DETERMINING CHANGES IN OCULOVISUAL FUNCTIONS AND ANTERIOR CORNEAL CURVATURE RELA-TIVE TO PTERYGIUM TYPES <p><strong>Introduction: </strong>Dryweight in pterygium is more towards the fleshy appearance of the fibrous tissue. <strong>Aim: </strong>The goal of this study was to determine the predictive ability of net pterygium tissue mass (dryweight) on predicting changes in anterior corneal curvature and oculovisual functions relative to pterygium types. <strong>Methodology:</strong> A total of 93 primary pterygium patients who visited an ophthalmology clinic were selected as participants. The net pterygium tissue mass were obtained via freeze dry method subsequent to pterygium excision using fibrin glue adhesive method. Best corrected visual acuity (BCVA) and contrast sensitivity function (CSF) were measured by using M&amp;S Smart System II as measurement for oculovisual function, while the changes of anterior corneal curvature was measured using corneal topography. <strong>Results:</strong> The mean and standard deviation for BCVA, CSF and SimK were 0.44 ± 0.30 LogMAR, 24.28 ± 17.66 % and 4.64 ± 4.18 D respectively. This study found that the predictive ability of pterygium dryweight with BCVA were strong in Type I and Type III while moderate in Type II with 13.10% (R<sup>2</sup> = 0.131, <em>p </em>&lt; 0.05) in Type I. Slight increase trend were noted in both Type II with 53% (R<sup>2</sup> = 0.530, <em>p</em> &lt; 0.05) and Type III, with 21.60% (R<sup>2 </sup>= 0.216, <em>p</em> &lt; 0.05). For CSF, the predictive ability of pterygium dryweight were strong in all types with Type I, Type II and III reported 21.6% (R<sup>2 </sup>= 0.216, <em>p</em> &lt; 0.05), 31.8% (R<sup>2 </sup>= 0.318, <em>p</em> &lt; 0.05), 28.9% (R<sup>2 </sup>= 0.289, <em>p</em> &lt; 0.05) respectively.

This multifactorial disease has been found to be a major concern worldwide. This dental caries has been proved to be caused by the presence of oral pathogen. Seaweeds show many health-promoting effects, including antimicrobial, anti-inflammatory, anti-oxidative and anti-cancer properties. The versatility of the seaweed has attracted many researchers to use seaweed extracts as alternative treatment against multiple diseases. However, little attention has been paid to the application of antimicrobial properties of seaweed against oral pathogenic microorganisms. The substances isolated from red, brown and green seaweeds showing potent antimicrobial activity are polysaccharides, phlorotannins, pigments, fatty acids, lectins, terpenoids, alkaloids and halogenated compounds. Current research is shifting into fully grasping the antimicrobial potential of seaweeds against oral microbes that cause dental caries or periodontal disease. Hence, this mini-review will highlight the antimicrobial properties of three types of seaweed species (red, brown, and green) against selected oral pathogenic microorganisms.</p> NURUL NAJWA ZAMIMI, NOORHAZAYTI AB.

However, this information is crucial in order to quantify the variations in surgeon’s surgical technique and to further evaluate the surgeon’s surgically induced astigmatism (SIA) predictability. <strong>Aim: </strong>To assess the effectiveness of Phacoemulsification Technique Related to Surgically Induced Astigmatism (PTechSIA) questionnaire in quantifying the phacoemulsification surgical technique variations. <strong>Methods: </strong>Four ophthalmic surgeons (Surgeons A, B, C and D<strong>) </strong>at IIUM Eye Specialist Clinic were involved in this study<strong>.</strong> A validated self-administered questionnaire with 9 items (PTechSIA, patency number: LY2018002935) was employed to assess the surgeons’ surgical techniques during phacoemulsification. All the responds were scored for each item using Variation Score (VS). Score ‘0’ was given, when a surgeon ticked only one option of the surgical techniques, Score ‘1’ when a surgeon ticked two options, and so on for each item. VSs of all 9 items were summed up to obtain Total Variation Score (TVS). A higher TVS indicated a higher variation in surgical techniques. <strong>Results:</strong> PTechSIA showed that all surgeons had different TVS. Surgeons A and B had TVS of 1, whereas Surgeons C and D had TVS of 0 and 3, respectively. TVS of each surgeon indicated that all surgeons had variations in phacoemulsification surgical techniques. <strong>Conclusions:</strong> PTechSIA is an effective tool to evaluate and quantify the variation of surgeons’ surgical techniques in phacoemulsification. Hence, PTechSIA is suggested to be used extensively for a larger scale of surgeons in future research related to phacoemulsification surgical technique and SIA.</p> NAZARYNA MARZUKI, MD MUZIMAN SYAH MD MUSTAFA, NOORHAZAYTI AB.

Information on participants’ age, gender, type of contact lens wear, and duration of wearing contact lens were included. <strong>Results: </strong>A total of 140 contact lens wearer completed the online survey with 94.3% of female participants. The type of contact lens used by the participants were mostly soft contact lens (98.6%) with monthly disposable modality (75.0%) followed by daily disposable modality (15.7%). Most of the participants reported eye discomfort “sometimes” (48.6%) for the last 2 weeks with the intensity level of discomfort on scale “3” (31.4%), followed by dryness “sometimes” (39.3%) with intensity of “2” (29.3%) at the end of the wearing time. There are significant correlation between age and the dry eyes symptoms which are the frequency of eyes discomfort and having to remove lenses (p &lt; 0.05). However, there is no association between the duration of contact lens wear and the dry eyes symptoms (p &gt; 0.05). <strong>Conclusion: </strong>Eye dryness is the most reported symptom which is more frequent and intense at the end of wearing time.</p> SYAHIRAH AMERAH MOHAMAD DAUD, NOOR EZAILINA BADARUDIN Copyright (c) 2020 INTERNATIONAL JOURNAL OF ALLIED HEALTH SCIENCES Tue, 25 Feb 2020 10:57:20 +0800 THE PRIVATE OPTOMETRY PRACTICES IN MALAYSIA: THE PROFESSIONAL SERVICES <p>The prevalence of private optometry practices that achieve the minimum standard operation procedure (SOP) in eye examination by Ministry of Health Malaysia and number of referral cases by private practices to the hospitals are identified in order to ensure the eye care services from optometrists in Malaysia can be optimized. An online survey has been distributed to all private optometrists with Annual Practicing Certificate (APC) of 2017 through their private email address;&nbsp; through alumni WhatsApp groups of all Optometry schools in Malaysia; and to the members of the Association of Malaysian Optometrists (AMO).The survey included questions on their demographics, available equipment, ophthalmic procedures routinely conducted in practice, barriers to provide routine procedures, special optometric clinic provided and the number of referral cases to hospitals. Respondents answered the questions given within the time frame of 1<sup>st</sup> September 2018 until 28<sup>th</sup> February 2019. Seventy-one (N=71) optometrists had responded the survey. Most practices had basic optometric instruments to conduct visual testing and refraction; equipments such as illuminated or projected Snellen chart (95.8%), retinoscopy (88.7%) and complete trial set (100.0%); but not the other essential equipments:&nbsp; direct ophthalmoscopes (78.9%), slit lamp biomicroscopy (67.6%), keratometry (46.5%) and RAF rules (46.5%). The lack of such essential equipment corresponds to the low number of practices conducting the respective procedures routinely. Most of respondents stated the reason for not providing full eye check-up in practices were due to unavailability of equipment (79.1%), lack of time (59.7%) and requested by the customers (34.3%). For the referral cases, private optometry practice only referred 0-20 cases per month. This study brings forward several suggestions to improve the present situation of eye care services in Malaysia. The data elicited in this study may be used as a basis to fulfill the demanding eye-care needs and determining the training and support guidelines for the efficient optometric services in Malaysia.</p> RAIHANA IZZATI ABD AZIZ, FATIN ARYANI AHMAD MAFAKHIR, NOOR EZAILINA BADARUDIN, NAJIHAH MUHAMMAD SHARIF Copyright (c) 2020 INTERNATIONAL JOURNAL OF ALLIED HEALTH SCIENCES Tue, 25 Feb 2020 10:58:14 +0800 THE ASSOCIATION BETWEEN ASTIGMATIC ANISOMETROPIA WITH VISUAL ACUITY AND STEREOPSIS <p><strong>Aim:</strong> To study the association between astigmatic anisometropia with visual acuity (VA) and stereopsis.</p> <p><strong>Methodology:</strong> Twenty emmetropic adults with normal binocularity in age of 18 to 34 years old, were recruited. Unilateral against-the-rule astigmatism anisometropia was induced in each participant by using -1DC, -2DC, -3DC and -4DC toric soft contact lenses. Distance VA is measured using logMAR chart, near VA is measured using Roman Test types chart, and stereopsis using TNO plates were assessed.</p> <p><strong>Results:</strong> All participants showed a reduction in VA at distance and near, and stereopsis with the increasing values of astigmatic anisometropia by using correlation analysis. The correlation of induced astigmatic anisometropia with distance VA was a weak positive correlation, (<em>r</em> = 0.589, <em>p</em> = &lt;0.05), and moderate positive correlation (<em>r</em> = 0.602, <em>p</em> = &lt;0.05) with near VA. Stereopsis was similarly degraded and showed weak positive correlation (<em>r</em> = 0.589,<em> p</em> = &lt;0.05). Both acuities showed significant reduction in each 1D increment of astigmatic anisometropia by 1 line, meanwhile stereopsis showed significant reduction by 2 lines. Stereopsis is affected the most.

Their visual acuity, color discrimination and stereopsis were assessed using logMAR chart, Farnsworth D-15 (percentage of correct caps arrangement) and TNO stereo test respectively. Their pupil reflexes (mm) in both photopic and scotopic condition, and rates of pupil responses which are velocity from mydriasis to miosis (mm/s) were measured using Oculus Keratograph 5M.</p> <p><strong>Results: </strong>There are significant reduction in visual acuity, color discrimination ability and stereopsis in elderly group (<em>p</em>&lt; 0.05). It is also revealed that elderly had diminished pupil reflexes in scotopic condition and reduced pupil velocity compared to adults and pediatrics (<em>p</em>&lt; 0.05). However, for pupil reflexes in photopic condition (miosis), there are no significant difference between pediatrics, adults and elderly (<em>p</em>&gt; 0.05).</p> <p><strong>Conclusion: </strong>This study indicates that visual acuity, color discrimination ability and stereopsis are inversely proportional to increase of age which might be due to physiological lenticular deterioration and changes in cortical activity which induced by changes in levels of neurotransmitters. Diminished pupil responses in old age might be caused by senile miosis which mediated by reduction in sympathetic input. These age-related physiological changes will cause reduction in quality of life of elderly and affect their mobility.</p> SITI ERNY ZULAIKA MOHD ZULKIFLY, MOHD HAFIEZZUDDIN MOHD HASHIM, NORSHAM AHMAD Copyright (c) 2020 INTERNATIONAL JOURNAL OF ALLIED HEALTH SCIENCES Tue, 25 Feb 2020 11:00:14 +0800 VISUAL FUNCTIONS STATUS IN GERIATRIC NURSING HOME KUANTAN <p><strong>Introduction:</strong> Age related visual impairment and eye diseases are one of the real worries among the different issues that influence the geriatric population on the grounds that their visual status plays major role in the quality of life. The aim of this study was to investigate the visual function status and eye diseases among the old individuals in a nursing home. <strong>Methods:</strong> A total of 43 elderly (males and females) in range age from 51 to 78 years who stayed at nursing centre were examined in this study. The parameters such as visual acuity, colour vision, stereopsis and any eye disorder were collected. There were no incorporation and prohibition criteria in the study. &nbsp;The tools used to measure them were LogMAR chart (at 3 metres), Farnsworth D-15, TNO booklet, portable slit lamp and direct ophthalmoscopy respectively. <strong>Results:</strong> The outcome demonstrates some of them mostly have cataracts (Nuclear 55.8%; Cortical 4.7%; PSCC 4.7%), pterygium (16.3%), arcus senilis (4.7%) and diabetic retinopathy (2.3%).

It has been used in many applications and products as they possess interesting biological activities that give benefit to the dental and medical area. <strong>Aims:</strong> The objectives of this study were to determine the growth curve of <em>Streptococcus mutans </em>and Lactobacillus casei, and also to determine minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) value of <em>Sargassum polycystum </em>extract against <em>Streptococcus mutans</em> and <em>Lactobacillus casei</em>. <strong>Materials and methods: </strong>The growth of both bacteria were studied by growth curve analysis. Besides that, the antibacterial activity of <em>Sargassum polycystum </em>ethanol extracts against two oral cariogenic bacteria were examined using broth dilution method. The bioactivity of the seaweed extract was studied by finding the MIC and MBC value. <strong>Results:</strong> The time taken for the <em>Streptococcus mutans and Lactobacillus casei</em> to achieve exponential phase during growth is 4 and 5 hours respectively. MIC values of ethanol extracts of <em>Sargassum polycystum</em> in different concentration against <em>Streptococcus mutans </em>and <em>Lactobacillus casei</em> were unreliable because the presence of fungus (white-precipitate) at all 96-well plates including the positive and negative control. As there was no MIC value, partial inhibition was determined by calculating the optical density. Therefore, MBC analysis was unable to carry out because the MIC values were unreliable. <strong>Conclusion: </strong>The ethanol extract of <em>Sargassum polycystum </em>used in this study show partial bacterial inhibition against pathogens used. Therefore, the same study by using different type of solvent are recommended to be carried out in the future.</p> NOORHAZAYTI AB.
