Ocular chemical injury is a true ophthalmic emergency requiring immediate medical intervention. Damages can be devastating and potentially resulting in blindness, corneal perforation and phthisis bulbi. We describe here a successful treatment outcome in a patient who sustained Roper-Hall Grade 4 injury to both eyes. Patient received medical therapy followed by serial ocular surgeries with eventual visual recovery in one eye from counting finger to 6/15 after a decade. In conclusion, after maximum medical therapy, a carefully planned serial surgeries of cultivated oral mucosal epithelial transplantation (COMET) and PK has proven beneficial for this patient with advanced limbal stem cell deficiency (LSCD).

The primary cause of 68 enucleations in the University Hospital, Kuala Lumpur, are reviewed and compared with those from Uganda and Jerusalem. Trauma 25% especially in the 20 - 29 age group was the most important cause, followed by corneal diseases 22% seen largely over the age of 50. Malignant tumours 16% consisting nearly all of retinoblastoma and a very low incidence of malignant melanoma when compared with the Caucasians. Glaucoma 12% was mainly of the narrow angle type. Males predominate nearly all age groups with an overall ratio of 2:1 and a peak of 5:1 in trauma.

Erythropoietin (EPO) is a glycoprotein hormone conventionally thought to be responsible only in producing red blood cells in our body. However, with the discovery of the presence of EPO and EPO receptors in the retinal layers, the EPO seems to have physiological roles in the eye. In this review, we revisit the role of EPO in the eye. We look into the biological role of EPO in the development of the eye and the physiologic roles that it has. Apart from that, we seek to understand the mechanisms and pathways of EPO that contributes to the therapeutic and pathological conditions of the various ocular disorders such as diabetic retinopathy, retinopathy of prematurity, glaucoma, age-related macular degeneration, optic neuritis, and retinal detachment. With these understandings, we discuss the clinical applications of EPO for treatment of ocular disorders, modes of administration, EPO formulations, current clinical trials, and its future directions.

Retinoblastoma was clinically diagnosed in 38 patients in the University Hospital between 1968 to 1988. White pupil or cat's eye reflex, found in 25 patients, was the most common symptom. Four patients refused any form of treatment. Of the 27 histopathologically confirmed cases, 16 were males and 11 were females. There was no ethnic group predominance, although a male preponderance was observed among Malay patients (M:F 3:1, p less than 0.05). Treatment in cases with unilateral disease, without extra ocular extension consisted of enucleation of the involved eye, with close examination of the contralateral eye in follow-up. In cases presenting with bilateral tumour the worse eye was removed. Of 20 cases of histopathologically proven unilateral retinoblastoma treated surgically, 12 patients survived for a mean period of 4.5 years (Range: 1-19 years). The defaulter rate for this group of patients was 55%. None of the 7 cases of bilateral retinoblastoma survived beyond 5 years (Mean survival 2.5 years).

Spontaneous unilateral orbital haematoma in children is not common and very rarely caused by scurvy. Scurvy is a clinical syndrome with a spectrum of clinical manifestations due to severe prolonged vitamin C deficiency leading to impairment of collagen synthesis over skin, bone, teeth and blood vessels. This paper presents a unique case of a 7- year-old girl with learning difficulty who presented with spontaneous right proptosis due to scurvy. Imaging studies suggestive of intra- orbital extraconal haemorrhage. The child was treated with a higher than recommended dose of vitamin C initially in emergency situation. She responded well and discharged without complication. Spontaneous orbital haematoma due to scurvy is very rare with less than 10 cases published in literature. The present case should raise the awareness regarding this forgotten disease and importance of balance nutrition amongst children.

Surgical approaches are becoming increasingly minimally invasive, without compromising either safety or ease. Penetrating ocular foreign bodies has traditionally been approached either by intraocular or supraorbital access. We successfully attempted a minimally invasive approach to remove a retrobulbar foreign body under computer-assisted image guidance in a 19-year-old man involved in an industrial mishap.

PMID: 10879232

A total of 89 histopathologically proven ocular tumours and tumour-like lesions treated in Hospital University Sains Malaysia, Kubang Kerian, Kelantan over a period of nine years were reviewed for their age distribution, site of lesion and histological type. The tumours were observed in all age groups with a maximum prevalence in the first decade. Twenty lesions were malignant and 69 were benign. The eyelid was the most frequent location (51%), followed by the conjunctiva (32%). Retinoblastoma was the most common malignant tumour (10 cases) and dermoid cyst was the most common tumour-like lesion (16 cases).

The epidemiology of Open Globe Injuries presenting to a tertiary referral eye hospital in Australia

Beshay N, Keay L, Dunn H, Kamalden TA, Hoskin AK, Watson SL

Injury, 2017 Jul;48(7):1348-1354.

PMID: 28438416 DOI: 10.1016/j.injury.2017.04.035

BACKGROUND: Open globe injuries (OGIs) account for 44% of the cost of ocular trauma within Australia. It is estimated that 90% of ocular trauma is preventable. However, there have been few epidemiological studies within Australia that have identified groups at risk of OGIs specifically. The aim of our study was to review the epidemiology of OGIs presenting to a tertiary referral eye hospital in Australia.

METHODS: The Birmingham Eye Trauma Terminology (BETT) system was used to classify injuries as globe ruptures, penetrating eye injuries (PEIs), intraocular foreign bodies (IOFBs) or perforating injuries. Demographic data, past ocular history, mechanism of trauma, ocular injuries, and best-corrected visual acuity (BCVA) before and after treatment were recorded.

RESULTS: The 205 OGIs included 80 globe ruptures, 71 PEIs, 48 IOFBs and six perforating injuries. Falls predominated in older age groups compared to the other mechanisms of injury (p<0.0001). A fall was responsible for 33 globe ruptures and 82% of these had a history of previous intraocular surgery. Globe rupture and perforating injuries had poorer visual outcomes (p<0.05), consistent with previous studies. Alcohol was implicated in 20 cases of OGI, with 11 of these due to assault. PEIs and IOFBs commonly occurred while working with metal. BCVA was significantly worse following removal of an intraocular foreign body. We found presenting BCVA to be a good predictor of BCVA at the time of discharge.

CONCLUSIONS: The causes of OGI varied in association with age, with older people mostly incurring their OGI through falls and younger adults through assault and working with metal. Globe ruptures occurring after a fall often had a history of intraocular surgery. The initial BCVA is useful for non-ophthalmologists who are unfamiliar with the ocular trauma score to help predict the BCVA following treatment.

Fulltext Role of intravitreal/intracameral antibiotics to prevent traumatic endophthalmitis - Meta-analysis

Thevi T, Abas AL

Indian J Ophthalmol, 2017 Oct;65(10):920-925.

Traumatic endophthalmitis is a devastating condition that can occur following an open globe injury and result in loss of vision. The use of prophylactic antibiotics is empirical as most surgeons fear complications associated with the same. No systematic review has been performed in English on the role of intravitreal/intracameral antibiotics in preventing traumatic endophthalmitis. We searched for randomized controlled trials and controlled clinical trials comparing intracameral/intravitreal antibiotics with placebos on PubMed, Google Scholar, Science Direct, and Cochrane Library using keywords open globe/trauma/penetrating/perforating injuries endophthalmitis. The last search was on 5 May 2017. We included patients of all ages with open globe injuries who received intracameral/intravitreal antibiotics, regardless of the dose. Quality of the trials was assessed using Cochrane collaboration tools to assess the risk of bias. The main outcome measures were endophthalmitis and visual acuity. We included three trials. Overall, intravitreal/intracameral antibiotics were noted to significantly reduce the occurrence of endophthalmitis in open globe injuries (relative risk [RR] 0.19, 95% confidence interval [CI] 0.06-0.57). The use of intravitreal/intracameral antibiotics did not have an effect in improving visual acuity (RR 1.17, 95% CI 0.61-2.23). Two trials (Narang 2003; Soheilan 2001) were observed to have no significant effect on visual acuity while another trial (Soheilan 2007) did not list visual acuity as part of its objectives. Intracameral/intravitreal antibiotics reduce the risk of endophthalmitis in open globe injuries; although, there was no improvement in the visual acuity. We, therefore, recommend the use of intravitreal/intracameral injections in open globe injuries to prevent this devastating complication.

Fulltext Feature selection and classifier parameters estimation for EEG signals peak detection using particle swarm optimization

Adam A, Shapiai MI, Tumari MZ, Mohamad MS, Mubin M

PMID: 25243236 DOI: 10.1155/2014/973063

Electroencephalogram (EEG) signal peak detection is widely used in clinical applications. The peak point can be detected using several approaches, including time, frequency, time-frequency, and nonlinear domains depending on various peak features from several models. However, there is no study that provides the importance of every peak feature in contributing to a good and generalized model. In this study, feature selection and classifier parameters estimation based on particle swarm optimization (PSO) are proposed as a framework for peak detection on EEG signals in time domain analysis. Two versions of PSO are used in the study: (1) standard PSO and (2) random asynchronous particle swarm optimization (RA-PSO). The proposed framework tries to find the best combination of all the available features that offers good peak detection and a high classification rate from the results in the conducted experiments. The evaluation results indicate that the accuracy of the peak detection can be improved up to 99.90% and 98.59% for training and testing, respectively, as compared to the framework without feature selection adaptation. Additionally, the proposed framework based on RA-PSO offers a better and reliable classification rate as compared to standard PSO as it produces low variance model.

Different Intraorbital Implant Situations and Ocular Prosthetic Rehabilitation

Aggarwal H, Kumar P, Eachempati P, Alvi HA

PMID: 26447725 DOI: 10.1111/jopr.12369

Enucleation is the removal of the entire globe of the eye and a portion of the optic nerve, while evisceration involves the removal of the contents of the globe leaving the sclera, extraocular muscles, and optic nerve. Following enucleation or evisceration, intraorbital implants are routinely placed to enhance the prosthetic outcome in addition to restoring the lost orbital volume. Current practice employs intraorbital implants made of nonporous silicone, hydroxyapatite, or porous polyethylene. Intraorbital implant selection and placement, being a highly demanding procedure in terms of knowledge, skill, and expertise, may be associated with a multiplicity of technical and surgical errors. Complications are usually minimal with these implants, but they do occur. The literature reveals many articles related to intraorbital implants, their benefits, and complications; however, the literature regarding the effect of various intraorbital implant situations on the subsequent prosthetic rehabilitation is markedly scarce. Moreover, the need for interdisciplinary surgical and prosthetic interventions required for successful rehabilitation in cases of compromised implant situations has been underemphasized. Hence, this review aimed to evaluate the effect of different intraorbital implant situations on ocular rehabilitation and the required interdisciplinary surgical and prosthetic treatment approach for rehabilitation of enucleated/eviscerated sockets with compromised implant situations, to provide a critical appraisal, and to present a simplified management strategy.
