Fulltext Central Retinal Artery Occlusion with Sparing of Cilioretinal Artery Post Pulmonary Artery Stenting

Oo KT, Mohd-Zain MR, Shatriah I

Cureus, 2018 Jan 29;10(1):e2128.
PMID: 29607276 DOI: 10.7759/cureus.2128

Central retinal arterial occlusion is an ocular emergency. Central retinal artery occlusion following cardiac procedures have been described in adults. We describe a pediatric patient who developed central retinal artery occlusion following pulmonary artery stenting. It is important to highlight this potential risk to ensure early diagnosis and prompt treatment.
Fulltext Concomitant abducens and facial nerve palsies: A rare presentation in anti-aquaporin-4 antibody-positive neuromyelitis optica

Oo KT, Tay KS, Law WC, Shatriah I

Taiwan J Ophthalmol, 2019 12 05;10(3):235-238.

Over the past decade, the discovery of disease-specific aquaporin-4 antibodies has led to a better understanding of the diverse spectrum of disorders that are associated with neuromyelitis optica. Brainstem manifestations have been increasingly recognized in this disease. However, multiple cranial nerve palsies as an initial presentation of neuromyelitis optica are uncommon. We report a rare case of anti-aquaporin-4 antibody-positive neuromyelitis optica that presented with unilateral abducens and facial nerve palsies. Notably, this case did not involve the optic nerve or the spinal cord. Diagnosing neuromyelitis optica that presents as an isolated acute brainstem syndrome is challenging, but the outcome may be devastating if the diagnosis is delayed.
Fulltext Efficacy of WINROP as a Screening Tool for Retinopathy of Prematurity in the East Coast of Malaysia

Lim ZD, Oo KT, Tai ELM, Shatriah I

Purpose: To evaluate the efficacy of the "weight, insulin-like growth factor 1, neonatal retinopathy of prematurity" (WINROP) algorithm in predicting retinopathy of prematurity (ROP) requiring treatment in Malaysia.
Participants: This was a retrospective study involving premature infants with gestational age less than 32 weeks treated from September 2016 to March 2019 in Hospital Universiti Sains Malaysia. Clinical diagnosis was made based on Early Treatment Retinopathy of Prematurity study. Participants' weekly weight gain since birth was entered in the website (http://winrop.com), along with date of birth, gestational age and final clinical examination outcome. WINROP software signals an alarm if an infant is at high risk of developing ROP requiring treatment during weight data entry. By using the alarm status, the sensitivity and specificity of this algorithm for predicting ROP requiring treatment were obtained.
Results: Ninety-two infants were included in this study. An alarm was detected in 67 infants (72.8%). There were a total of 53 infants (54.6%) with no ROP, 15 (16.3%) of whom developed stage 1 ROP, 10 (10.8%) who developed stage 2 ROP and 14 infants (15.2%) who developed stage 3 ROP. In our study, WINROP sensitivity was 95.2% and specificity was 33.8%.
Conclusion: WINROP is recommended as an initial screening tool for premature infants at risk of developing treatment-requiring ROP in Malaysia. It may help to alert clinicians managing severely ill infants when clinical examinations are less possible.

Primary angle closure glaucoma (PACG) is a major cause of blindness worldwide. We conducted a genome-wide association study (GWAS) followed by replication in a combined total of 10,503 PACG cases and 29,567 controls drawn from 24 countries across Asia, Australia, Europe, North America, and South America. We observed significant evidence of disease association at five new genetic loci upon meta-analysis of all patient collections. These loci are at EPDR1 rs3816415 (odds ratio (OR) = 1.24, P = 5.94 × 10(-15)), CHAT rs1258267 (OR = 1.22, P = 2.85 × 10(-16)), GLIS3 rs736893 (OR = 1.18, P = 1.43 × 10(-14)), FERMT2 rs7494379 (OR = 1.14, P = 3.43 × 10(-11)), and DPM2-FAM102A rs3739821 (OR = 1.15, P = 8.32 × 10(-12)). We also confirmed significant association at three previously described loci (P < 5 × 10(-8) for each sentinel SNP at PLEKHA7, COL11A1, and PCMTD1-ST18), providing new insights into the biology of PACG.
