    The aim of the study is to evaluate the effects of contact and non-contact laser photocoagulation (LP) on ocular surface changes and Ocular Surface Disease Index (OSDI) score in patients with proliferative diabetic retinopathy (PDR). This was a single center, prospective, randomised, parallel-controlled trial of pilot study in Hospital Universiti Sains Malaysia between June 2013 and May 2014. Eye with PDR was selected and randomised into 2 groups (Contact LP group and Non-contact LP group) by using random sampling envelope method. Contact LP group was treated with contact LP via slit lamp laser delivery system. Non-contact LP group was treated with non-contact LP via binocular laser indirect ophthalmoscopy system. Main outcome measures were Schirmer test value, tear film break-up time (TBUT) and OSDI score at baseline and at 3 months post laser therapy. Statistical analyses were performed using SPSS version 22.0. A total of 60 eyes were recruited (30 eyes in Contact LP and 30 eyes in Non-contact LP). Contact LP showed significant reduction of TBUT (p = 0.038) and significant increase in mean OSDI score (p = 0.001) at 3 months post laser therapy. However, there was no significant difference of mean change of Schirmer test value and TBUT between the two groups except for OSDI score (p = 0.044). Both mode of laser deliveries (contact LP and non-contact LP) showed comparable effects on ocular surface disease in PDR patient that underwent laser pan retinal photocoagulation.

    We report a case of dural carotid cavernous fistula (CCF) pose a diagnostic dilemma with initial symptoms of the arteriovenous shunt. A 56 year-old man presented with right eye diplopia, thensubsequently developed ptosis, congestion of conjunctiva, dilated episcleral vessels, and gradual rise in intraocular pressure. Initial diagnosis of pseudotumour was made based on negative finding of CCF by computed tomography angiography (CTA). In view of persistent clinical manifestations in spite of steroid therapy, and with the presence of new ocular signs; cock-screw conjunctival vessels, dilated retinal veins, and proptosis, digital subtraction angiography (DSA) was performed and confirmed the diagnosis of dural CCF.The ocular symptoms resolved completely post embolization of the fistula.

    Macular branch retinal vein occlusion (BRVO), a type of retinal vein occlusion, is rarely recognised as a distinct entity. Macular BRVO has unique clinical features and different natural courses than the major BRVO. We report a case of a young patient with macular BRVO with macular oedema who was successfully treated with intravitreal ranibizumab injection. A 43 year-old Chinese man with no underlying medical illness presented with 2 weeks history of left eye painless reduced central vision which was worsening over time. On examination, his left eye visual acuity was 6/30 and Amsler chart drawing showed a lower central scotoma. Dilated fundus examination found marked flame-shaped retinal hemorrhages with cotton wool spot over the superior macular area bounded superiorly by superior arcade and macular thickening. An optical coherence tomography revealed cystoid macular oedema; and fundus fluorescein angiography showed occlusion of a small venous branch draining a superior part of macula to superior temporal venous arcade. A complete medical investigation found that he has hypertriglyceridemia and he was managed accordingly. His vision had improved to 6/6 after receiving 3 injections of intravitreal ranibizumab with no residual central scotoma and complete resolution of macular oedema.

    We report a case of visually impaired glaucoma patient with long term use of topical glaucoma medications presented with a corneal ulcer due to the improper technique of eye drop instillation. A 70-year-old gentleman with advanced primary open angle glaucoma (POAG) on his right eye and absolute glaucoma on his left eye, presented with painful redness and purulent discharge of the right eye for two weeks. He was using four types of topical glaucoma medication on his right eye since failed trabeculectomy two years ago. His right eye vision was 6/24 and painless blindness of the left eye before the presentation. He was administering all the medications himself despite his current vision status. Right eye examination showed visual acuity of 3/60 with clinical features of corneal ulcer. During the observation of his eye drop instillation technique, he consistently touched the tip of the bottle to his right cornea. The corneal contact area corresponded to the corneal ulcer area and size. In addition to this, the culture result obtained from both corneal ulcer and the bottles’ tips yielded similar microorganism which was Staphylococcus aureus. After an intensive course of topical antibiotics treatment, the corneal ulcer healed with a scar and the vision improved to 6/24 from 3/60. Although this incident is rare, it is crucial for the treating physicians to address the issue properly and co-manage these patients with pharmacists and nursing staffs as well as to seek support from the caretakers to prevent this blinding complication.

    Background: Laser photocoagulation has been the mainstay treatment for diabetic retinopathy (DR). However, the applied laser light must pass through multiple ocular structures such as the cornea to reach the retina, potentially causing thermal injury to non-target tissues. The purpose of this study was to examine the effects of 532 nm Argon laser pan-retinal photocoagulation (PRP) on corneal thickness and corneal endothelial cell parameters by comparing central corneal thickness (CCT), endothelial cell density (ECD), and endothelial cell area coefficient of variation (CoV) before and after PRP for proliferative diabetic retinopathy (PDR). The effect of laser PRP on these corneal parameters may help in adapting treatment protocols to reduce corneal damage and thereby improve patient outcome.

    Methods: This was a prospective cohort study involving newly diagnosed PDR patients. All patients underwent specular microscopy examination (CCT, ECD and endothelial cell area CoV) both pre-PRP and at 1-week and 6-weeks after the final PRP session (post-PRP). A Carl Zeiss Visulas Argon laser (532 nm) was used to perform PRP.

    Results: A total of 33 newly diagnosed PDR patients were included in this study. There were no significant differences in mean CCT, ECD, and endothelial cell area CoV at 1-week and 6-weeks following PRP compared to pre-treatment baseline (p > 0.05). Further, there were no significant correlations between laser energy delivered and CCT, ECD and endothelial cell area CoV at either post-PRP examination time.

    Conclusion: Argon laser (523 nm) energy delivered within recommended ranges for PRP had no adverse effects on corneal structure.

    Tunnel vision is a classic sign among patients with advanced glaucoma. However, other conditions such as retinitis pigmentosa, optic neuritis and rod-cone dystrophy may be characterized by similar visual field defects. A 52-year-old lady with a family history of glaucoma presented with bilateral gradual loss of peripheral vision for two years. She claimed to have poor night vision about 20 years prior to this presentation. Her visual acuity was 6/7.5 in both eyes. The anterior chamber depth was moderate bilaterally, with Schaffer grading on gonioscopy of grade I to II. The intraocular pressure was 14 mmHg in both eyes. The optic discs appeared normal. Fundus examination showed scattered hypopigmented changes sparing the fovea. Humphrey visual field test revealed bilateral constricted visual fields. She was diagnosed with retinitis punctata albescens (RPA) based on her symptom of poor night vision, supported by the diffuse hypopigmented changes in her fundi. The management of this condition involves careful counselling regarding the genetic nature of the disease and its progressive course. We discuss this case to illustrate the importance of a thorough history taking and careful fundus examination in the workup of patients presenting with tunnel vision.

    A 15-year-old boy presented with painless progressive blurring of vision in the right eye for 1 year in duration. His visual acuity in the right eye was hand movement. The right fundus showed presence of extensive subretinal exudates at the posterior pole and a retinal macrocyst at the temporal periphery. It was associated with exudative retinal detachment at the inferior periphery of the retina. Fundus angiography revealed telangiectatic retinal vessels at the superotemporal retina. Based on clinical and angiographic findings, a diagnosis of Coats disease was made. He was treated with retinal laser photocoagulation. There was resolution of the exudative retinal detachment, reduction of subretinal exudates, and regression of the retinal macrocyst with improvement of visual acuity to 1/60 post-laser therapy.

    The purpose of this study is to determine the prevalence of falls and its associated factors among elderly diabetes type 2 patients attending a tertiary center in Malaysia. We conducted a cross-sectional study among 288 elderly diabetes type 2. The data collected includes data on sociodemographic, diabetes history, comorbid diseases, drug use, and activity of daily living (Barthel's index). The patient also was examined physically, and balance and gait assessment was carried out. Prevalence of falls among elderly diabetes was 18.8%. Female gender (OR: 2.54, P < 0.05), age group more than 75 (OR: 2.97, P < 0.05), retinopathy (OR: 2.19, P < 0.05), and orthostatic hypotension (OR: 2.87, P < 0.05) were associated with higher risk for falls. High balance and gait score was associated with reduced risk of fall in elderly diabetes (OR: 0.89, P < 0.05). In conclusion, the factors that are associated with higher risk for falls among elderly diabetes were female sex, age group more than 75, presence of retinopathy, and orthostatic hypotension. Those who had higher balance and gait score were found to be less likely to fall compared with those with lower score.

    The aim of this study is to determine the risk factors for retinopathy of prematurity (ROP), and also to screen Norrie Disease Pseudoglioma (NDP) gene mutation in order to determine if mutation in the NDP gene may play a role in the development of ROP among Malay premature infants. This was a case control studyamong Malay premature infants from Hospital Universiti Sains Malaysia (USM) conducted from August 2011 to May 2013. Written consent were taken from their parents before conducting the study. The stage of ROP, systemic risk factors (gestational age and birth weight) and enviromental risk factors (oxygen exposure and duration of ventilation)were reviewed from patients’medical records. DNA was extracted from venous blood and subjected to polymerase chain reaction (PCR) before direct sequencing of NDP gene. A total of 56 Malay premature infants (Case group = 28 ROP premature infants, Controlgroup = 28 non-ROP premature infants)from Hospital USMwere enrolled in this study. Out of 28 premature infants with ROP, 11 (39.3%) premature infants were in stage 3. Only 1 (3.6%) premature infant in stage 4 and 2 (7.2%) premature infants in stage 5. The gestational age (p = 0.010) and birth weight (p = 0.010) were the significant risk factors for ROP. There was no significant difference ofenvironmental risk factors between the two groups. The NDPgene mutation was not detected in Malay premature infants with ROP and also in control group. The gestational age and birth weight were important risk factors of ROP.Although NDPgene mutations were being linked to ROP but NDPgene mutation was not detected in premature infants with ROPas well as premature infants with non-ROP among Malay ethnic background.

    A 22-year-old Malay female presented with left eye floaters for 2 weeks, associated with temporal visual field defect and metamorphopsia for 3 days. She has a guinea pig and a hedgehog at home, but denied being bitten or scratched by them. Her visual acuity at presentation was 6/12 on the left eye and 6/6 on the right eye. Her left eye relative afferent pupillary defect was barely positive with mild anterior chamber reaction. Fundus examination of the left eye showed mild vitritis, swollen optic disc with macular star, crops of active choroidal lesions at superonasal retina with a linear arrangement in the form of migratory track nasally. However, there were no nematodes seen on fundus examination. Investigations showed normal full blood count with no eosinophilia and positive serology test for Bartonella henselae. She was diagnosed to have dual infection - diffuse unilateral subacute neuroretinitis (DUSN), based on the presence of crops of choroidal lesions with migratory track, and cat scratch disease (CSD) based on a positive serological test. She was treated with oral albendazole 400 mg 12 hourly for 6 weeks for DUSN and oral doxycycline 100 mg 12 hourly for 4 weeks for CSD. Focal laser had been applied to the area of migratory track in the left eye. Her left eye vision improved to 6/6 at 1 month after treatment, with resolution of neuroretinitis.

    We report a case of myopic choroidal neovascularization that showed improvement after a single injection of ranibizumab. A 45-year-old Chinese man with high myopia presented with sudden onset painless central scotoma of his right eye of 2 weeks' duration. There was no history of trauma. His right eye vision on presentation was 6/30 which showed no improvement with pinhole. The right fundus showed myopic maculopathy at the posterior pole with subretinal hemorrhage at the inferotemporal fovea. The optic disc was tilted with inferotemporal peripapillary atrophy. There was a myopic maculopathy appearance in the macula of the left eye. Fundus fluorescein angiography revealed choroidal neovascularization at the fovea of the right eye. A diagnosis of right eye choroidal neovascularization secondary to myopic maculopathy was made. A single intravitreal injection of ranibizumab 0.05 mL was given. Ten weeks following intravitreal injection, vision had improved to 6/7.5, and repeated fundus fluorescein angiography showed absence of choroidal neovascularization. Follow-up at 6 months showed visual acuity had normalized to 6/6 with glasses, which was maintained up to 12 months following treatment. The right fundus showed no further subretinal hemorrhage with no new lesions.

    Optic perineuritis (OPN) is a subtype of optic neuritis (ON) in which the inflammatory process involves meningeal sheath surrounding the optic nerve. Clinically, OPN simulates ON. However, in contrast to ON, patient with OPN shows sparing of central vision, improves dramatically with high-dose corticosteroid, are more likely to experience recurrence after stopping treatment. We report a rare case of caecocentral scotoma observed in a female with typical ON symptoms. Her magnetic resonance imaging showed features in line with OPN. She was treated with intravenous methylprednisolone 1 g/day for five days followed by slow tapering dose of oral prednisolone for one month. Her vision improved dramatically with a resolution of visual field defect. No relapses seen within two years of follow-up.

    OBJECTIVES: To compare the anterior ocular segment biometry among Type 2 diabetes mellitus (DM) with no diabetic retinopathy (DR) and non-proliferative diabetic retinopathy (NPDR), and to evaluate the correlation of anterior ocular segment biometry with HbA1c level.

    METHODS: A cross-sectional study was conducted in Hospital Universiti Sains Malaysia, Kelantan from November 2013 till May 2016 among Type 2 DM patients (DM with no DR and DM with NPDR). The patients were evaluated for anterior ocular segment biometry [central corneal thickness (CCT), anterior chamber width (ACW), angle opening distance (AOD) and anterior chamber angle (ACA)] by using Anterior Segment Optical Coherence Tomography (AS-OCT). Three ml venous blood was taken for the measurement of HbA1c.

    RESULTS: A total of 150 patients were included in this study (DM with no DR: 50 patients, DM with NPDR: 50 patients, non DM: 50 patients as a control group). The mean CCT and ACW showed significant difference among the three groups (p < 0.001 and p = 0.015 respectively). Based on post hoc result, there were significant mean difference of CCT between non DM and DM with NPDR (mean difference 36.14 μm, p < 0.001) and also between non DM and DM with no DR (mean difference 31.48 μm, p = 0.003). The ACW was significantly narrower in DM with NPDR (11.39 mm SD 0.62) compared to DM with no DR (11.76 mm SD 0.53) (p = 0.012). There were no significant correlation between HbA1c and all the anterior ocular segment biometry.

    CONCLUSION: Diabetic patients have significantly thicker CCT regardless of retinopathy status whereas ACW was significantly narrower in DM with NPDR group compared to DM with no DR. There was no significant correlations between HbA1c and all anterior ocular segment biometry in diabetic patients regardless of DR status.

    Background To analyze the etiology of optic disc swelling (ODS) and compare the clinical features between non-arteritic anterior ischemic optic neuropathy (NA-AION) and optic neuritis (ON) at our center from January 2019 to January 2020. Methodology Clinical records of all patients who presented with ODS between January 2019 and January 2020 were reviewed. The collected data were analyzed using IBM SPSS Statistics for Windows (Version 23.0, IBM Corp., Armonk, NY, USA). Results A total of 70 eyes among 47 patients were included in this review. There were 24 patients (51%) who had unilateral ODS, while 23 patients (49.0%) had bilateral ODS. The most common etiology of unilateral ODS was ON (45.7%), NA-AION (25%), and neuroretinitis (12.5%). Among bilateral ODS, the most common cause was papilledema (30.4%), hypertensive retinopathy (21.7%), diabetic papillitis (13.1%), and optic disc drusen (13.1%). Among unilateral ODS, the mean onset age was significantly older in NA-AION cases than that in ON cases (57.5 years vs. 40.3 years, P = 0.016). Ocular pain was a significant clinical finding observed in ON cases (54.5%) and none in NA-AION cases (P = 0.043). Although there was no significant difference in the initial visual acuity (VA) between NA-AION and ON, the final VA was significantly improved in ON compared to NA-AION (0.31 ± 0.34 vs. 1.14 ± 1.00, P = 0.029). Conclusions Many differential diagnoses must be considered when a patient is presented with ODS. With the increased prevalence of hypertension and diabetes in Malaysia, it is not a surprise that both hypertensive retinopathy and diabetic papillitis together accounted for one-third of the bilateral ODS patients.

    Valsalva retinopathy is an uncommon type of retinopathy that manifests as a rapid and painless vision decline, typically observed in young individuals without prior medical conditions. This condition arises from an elevated pressure within the veins of the eye, causing preretinal haemorrhage with a notable tendency to impact the macula. We describe here a case of valsalva-related sub-internal limiting membrane (sub-ILM) macular haemorrhage which was successfully treated with anti-vascular endothelial growth factor (anti-VEGF). A 27-year-old woman presented with a clinical presentation of a large sub-ILM macular haemorrhage resulting from a valsalva maneuver following a prolonged severe cough. The sub-ILM macular haemorrhage was completely resolved after being treated with three injections of intravitreal ranibizumab with a visual recovery of vision from counting fingers to 20/20 on three month follow-up.
