Get PDFAbdul-Rahim Haslinda, Yaakub Azhany, Rasid Noor-Khairul, Embong Zunaina, Ahmad-Tajudin Liza-Sharmini Department of Ophthalmology, School of Medical Sciences, Health Campus, Universiti Sains Malaysia, Kubang Kerian, Kelantan, Malaysia Abstract: We demonstrated a noninvasive management of early bleb leak following trabeculectomy using cyanoacrylate tissue glue (CATG). Three patients who underwent augmented trabeculectomy with mitomycin C with early bleb leak between January 2009 and June 2010 were reviewed. Case 1 and Case 2 exhibited bleb leak on postoperative Day 1 and Case 3 showed leak on follow-up at postoperative Day 7. Case 1 was successfully sealed with CATG at postoperative Day 3, after failed pressure padding and bandage contact lens. Case 2 was successfully sealed with CATG at postoperative Day 3, after failed pressure padding and conjunctiva flap resuturing. In Case 3, the leaking conjunctival flap was managed with combined techniques of resuturing and applying CATG at postoperative Day 9, after failed pressure padding. During leakage, the intraocular pressure was low (6–8 mmHg) in all three cases, with shallow anterior chamber depth and absence of other complications such as choroidal detachment, hypotony maculopathy, or endophthalmitis. Foreign body sensation was the main complaint following the procedure. No clinical allergy reaction was documented. CATG may serve as a potential adjunctive and effective method in the management of posttrabeculectomy early bleb leak. Keywords: cyanoacrylate tissue glue, bleb leak, trabeculectomy, mitomycin
Evaluation Of PCR Method To Detect Fungal Aetiology In Microbial Keratitis.
Get PDFMicrobial keratitis is a serious ocular infection. It is often difficult to establish a microbial keratitis that is due to fungal infection. Inadequate therapy and
delayed diagnosis of fungal keratitis leads to generally poor visual outcomes.

Agreement of macular oedema features between FFA And HRT II and evaluation of visual function, macular oedema index and quality of life post laser photocoagulation in diabetic macular oedema
Get PDFObjectives: To evaluate the agreement of macular edema features between FFA and HRT, and also to
evaluate the visual function, macular edema index and quality of life between pre and post laser photocoagulation in diabetic macular edema.
Methodology: Sixty-seven patients were subjected to HRT, FFA (served as the gold standard) and laser
photocoagulation. The visual function, macular edema index and quality of life measurements were done at
baseline and three months post laser photocoagulation.
Results: Topographic edema map of HRT has better sensitivity and specificity compare with other modules.
There is a good agreement between topographic edema map and macular edema index (MEI) thickness map.
There were improvement in visual function, macular edema index, and quality of life at 3 months post laser
photocogulation.
Conclusion: Topographic edema map of HRT has better sensitivity compared with other modules. Good
agreement exists between topographic edema map and MEI thickness map. The visual function, macular
edema index and quality of life were improved post laser photocoagulation
The efficacy of intravitreal triamcinolone versus laser photocoagulation in the primary treatment of diabetic macular edema
Get PDFBackground
Diabetic macular oedema is the leading causes of blindness. Laser photocoagulation reduces the
risk of visual loss. However recurrences are common and despite laser treatment, patients with
diabetic macular oedema experienced progressive loss of vision. Stabilization of the blood
retinal barrier introduces a rationale for intravitreal triamcinolone treatment in diabetic macular
oedema.
Objective
This study is intended to compare the best corrected visual acuity and the macular oedema index
at 3 month of primary treatment for diabetic macular oedema between intravitreal triamcinolone
acetonide (IVTA) and laser photocoagulation.
Methods
This comparative pilot study consists of 40 diabetic patients with diabetic macular oedema. The
patients were randomized into two groups using envelope technique sampling procedure.
Treatment for diabetic macular oedema was based on the printed envelope technique selected for
every patient. Twenty patients were assigned for IVTA group (one injection of !VT A) and
another 20 patients for LASER group (one laser session). Main outcome measures were mean
BCVA and mean MEI at three months post treatment. The macular oedema index was quantified
using Heidelberg Retinal Tomography II.
Results
The mean difference for best corrected visual acuity at baseline [IVTA: 0.935 (0.223), LASER:
0.795 (0.315)] and at three months post treatment [IVTA: 0.405 (0.224), LASER: 0.525 (0.289)]
between !VT A and LASER group was not statistically significant (p = 0.113 and p = 0.151
respectively). The mean difference for macular oedema index at baseline [IVTA: 2.539 (0.914),
LASER: 2.139 (0.577)] and at three months post treatment [IVTA: 1.753 (0.614), LASER: 1.711
(0.472)] between IVTA and LASER group was also not statistically significant (p = 0.106 and p
= 0.811 respectively).
Conclusions
IVTA demonstrates good outcome comparable to laser photocoagulation as a primary treatment
for diabetic macular oedema at three months post treatment
Choroidal neovascularization secondary to Best’s vitelliform macular dystrophy in two siblings of a Malay family

We report three children from a Malay family of five siblings with Best's vitelliform macular dystrophy, in which two of them subsequently developed choroidal neovascularization. The possible pathogenesis of this rare condition is described and highlighted in this report. Keywords: Best’s vitelliform macula dystrophy, choroidal neovascularization, children, Mala
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
