RESUMO

Choroidal melanoma with ciliary body involvement is rare, especially in young adults and Asians. Here, we report the case of a young, healthy Chinese woman who complained of decreased vision in the left eye for one week. Her ocular examination and imaging were suggestive of choroidal melanoma involving the ciliary body. The patient underwent enucleation of the left eye. Close monitoring was needed, as the involvement of the ciliary body in choroidal melanoma is associated with a high risk of metastasis.

RESUMO

PURPOSE: Macular edema, serous retinal detachment, and retinal pigment epithelial detachment have been reported in patients with nephrotic syndrome. However, there is limited data about macular thickness in children with nephrotic syndrome. The aim of this study was to compare the mean macular thickness in children with nephrotic syndrome and in a control group and to correlate it with visual acuity and level of proteinuria. METHODS: The comparative cross-sectional study included 66 children aged 6 to 17 years with nephrotic syndrome and healthy control seen in two tertiary centers in Malaysia. We recorded demographic data, as well as visual acuity, level of proteinuria, and the mean macular thicknesses in both groups. The mean macular thickness was measured using Stratus optical coherence tomography according to nine areas of the Early Treatment Diabetic Retinopathy Study map. RESULTS: The mean foveal thickness was 238.15 ± 22.98 µm for children with nephrotic syndrome and 237.01 ± 22.60 µm for the control group. There was no significant difference in the mean macular thickness between the groups (p = 0.843). A significant correlation with visual acuity was observed in the superior outer macula (r = -0.41, p = 0.019), the nasal outer macula (r = -0.41, p = 0.019), and the inferior outer macula (r = -0.40, p = 0.021). There was no significant correlation between the mean macular thickness and level of proteinuria (p = 0.338), although those with higher levels of proteinuria demonstrated a trend towards increased macular thickness. CONCLUSIONS: The mean macular thickness in children with nephrotic syndrome was similar to that of healthy children. A significant correlation between the mean thickness of the outer macular layer and the presenting visual acuity was observed. There was no correlation between the mean macular thickness and the level of proteinuria.

RESUMO

Primary non-Hodgkin's lymphoma of the lacrimal sac is extremely rare, usually representing secondary involvement of systemic malignancy. We report a case of bilateral primary non-Hodgkin's lymphoma of the lacrimal sac presenting with bilateral medial canthal swelling for one month which was preceded by a history of chronic bilateral epiphora and a recurrent history of dacryocystitis. The symptoms partially responded to systemic antibiotics for the past three years. Clinical examination revealed bilateral diffuse erythematous medial canthal swelling extending to the upper cheeks. CT of the orbits and paranasal sinuses demonstrated soft tissue masses involving bilateral lacrimal sacs and ducts. Endoscopic dacryocystorhinostomy (DCR) with excision biopsy of both lacrimal sac was performed and histopathologically confirmed the diagnosis of extranodal marginal zone B-cell lymphoma. She completed six cycles of chemotherapy. The symptoms subsided and radiologically showed a significant reduction of soft tissue mass at bilateral nasolacrimal sacs and ducts after completion of chemotherapy. Recurrent atypical presentation of dacryocystitis with suboptimal response to standard treatment should raise a suspicion of secondary cause. Histopathological examination is therefore crucial to avoid delays in diagnosis and treatment.

RESUMO

Optic perineuritis (OPN) in pulmonary tuberculosis (PTB) patients while on anti-tuberculous treatment is rare. It may occur due to tuberculosis-immune reconstitution inflammatory syndrome (TB-IRIS). Visual prognosis is poor if not treated early. We report a rare case of bilateral OPN in an elderly patient on treatment for PTB. A 79-year-old Malay man presented with a painless bilateral blurring of vision for three weeks. He was diagnosed to have PTB and has been on anti-tuberculous treatment for five months. Visual acuity in both eyes was only counting fingers. Optic nerve function tests were significantly reduced bilaterally. Fundoscopy showed bilateral segmental temporal optic disc pallor. Both visual field assessments were constricted. Other infective screenings and tumor markers were negative. Neuro-imaging revealed bilateral OPN involving the intraorbital segment. High-dose intravenous corticosteroid therapy was commenced, followed by slow tapering of oral prednisolone. Anti-tuberculous treatment was continued for a total course of nine months. The left visual acuity improved to 3/60. However, the right eye vision remained poor. His general condition was good.

RESUMO

Platelets are a primary source of pro- and anti-angiogenic cytokines. However, the evidence of their role in retinopathy of prematurity (ROP) is controversial. This retrospective study aimed to compare mean weekly platelet counts between infants with and without ROP over the first 6 weeks of life. A total of 93 infants matched by gestational age and birth weight were recruited (31 with ROP, 62 without ROP). Weekly mean platelet counts and other related risk factors were documented. The repeated measure analysis of variance (ANOVA) and the repeated measure analysis of covariance (ANCOVA) were used to compare mean platelet counts over time between the two groups, with and without adjusting for confounders. We found significant differences in the weekly mean platelet counts of infants with and without ROP over the first 6 weeks of life (p = 0.002). These differences disappeared after adjusting for covariates (p = 0.489). Lower mean platelet counts in ROP infants are not directly related to ROP, but rather to the presence of other risk factors for ROP, such as culture-proven sepsis, blood transfusion and bronchopulmonary dysplasia.

RESUMO

Despite the recent developments in modern cataract surgery and the application of a vast array of new devices and machines, late in-the-bag intraocular lens dislocation remains a devastating, albeit rare, complication. Various nonsurgical and surgical techniques have been used to manage this complication. We report a case of spontaneous repositioning in the left eye of an anteriorly subluxated in-the-bag intraocular lens. The spontaneous repositioning may have been caused by antagonistic effects related to the topical administration of brimonidine and prednisolone. The dislocation was treated without aggressive manipulation or surgical intervention.

RESUMO Apesar dos recentes avanços na cirurgia moderna de catarata e da aplicação de uma ampla gama de novos dispositivos, o deslocamento tardio de uma lente intraocular dentro do saco capsular continua a ser uma complicação devastadora, ainda que rara. Várias técnicas cirúrgicas e não cirúrgicas têm sido usadas para tratar esta complicação. Este é o relato de um caso de reposicionamento espontâneo de uma lente intraocular sub-luxada anteriormente dentro do saco capsular do olho esquerdo. Este reposicionamento pode ter sido causado pelos efeitos opostos da aplicação tópica simultânea de brimonidina e prednisolona. O deslocamento foi tratado sem manipulação agressiva ou intervenção cirúrgica.

RESUMO

Vitrectomy surgery in proliferative diabetic retinopathy improves the vision-related quality of life. However, there is lack of data on the duration of maintenance of visual gains post vitrectomy. This study thus aimed to determine the survival time of visual gains and the prognostic factors of vision loss after vitrectomy surgery for complications of proliferative diabetic retinopathy. A retrospective cohort study was conducted in an ophthalmology clinic in Malaysia. We included 134 patients with type 2 diabetes mellitus on follow-up after vitrectomy for proliferative diabetic retinopathy. Visual acuity was measured using the log of minimum angle of resolution (LogMar). A gain of ≥0.3 LogMar sustained on two subsequent visits was considered evidence of visual improvement post vitrectomy. Subjects were considered to have vision loss when their post-operative visual acuity subsequently dropped by ≥0.3 LogMar. Kaplan-Meier analysis was used to determine the survival time of visual gains. Cox Proportional Hazard regression was used to determine the prognostic factors of vision loss. The median age of patients was 56.00 years (IQR ± 10.00). The median duration of diabetes mellitus was 14.00 years (IQR ± 10.00). Approximately 50% of patients with initial improvement post vitrectomy subsequently experienced vision loss. The survival time, i.e., the median time from surgery until the number of patients with vision loss formed half of the original cohort, was 14.63 months (95% CI: 9.95, 19.32). Ischemic heart disease was a significant prognostic factor of vision loss. Patients with underlying ischemic heart disease (adjusted HR: 1.97, 95% CI: 1.18, 3.33) had a higher risk of vision loss post vitrectomy, after adjusting for other factors. Approximately half the patients with initial visual gains post vitrectomy maintained their vision for at least one year. Ischemic heart disease was a poor prognostic factor for preservation of visual gains post vitrectomy.

RESUMO

PURPOSE: The available data on strabismus surgery in South East Asian countries are scarce. This study aimed to identify visual outcome and factors influencing surgical outcome of horizontal strabismus surgery in a Southeast Asian cohort. MATERIALS AND METHODS: A retrospective review of patients who underwent horizontal strabismus surgery between 2013 and 2017 in Hospital Universiti Sains Malaysia was conducted. Surgery was considered successful if the post-operative deviation was within 10 prism diopters at 6 months' postoperative period. Factors influencing the outcome of surgery at 6 months were identified. Chi-square and Fisher's exact tests were used in data analysis. RESULTS: Ninety-eight patients were included. Both genders were equally affected. Exotropia (58.2%) was the most common type. About 65.3% of patients had alternating strabismus, while 51% had an angle of deviation of more than 45 prism diopters. Amblyopia was documented in 14.3% of patients. Those operated on below 10 years of age comprised 64.3%. Ninety-four patients completed follow-ups at 6 months after the surgery. The success rate was 81.6%. Approximately 92% of the patients had best-corrected visual acuities of 6/12 and better at 6 months' postoperative period. There was no significant association between age of onset, gender, presence of amblyopia, type of deviation, amount of deviation, and postoperative best-corrected visual acuity with surgical outcome at 6 months' postoperative period (P > 0.05). CONCLUSION: The success rate was good. Postoperative best-corrected visual acuity was promising. Age of onset, gender, presence of amblyopia, type of deviation, amount of deviation, and postoperative best-corrected visual acuity did not influence the outcome of horizontal strabismus surgery in our review.

RESUMO

Purpose To describe the visual presentation and factors affecting visual outcome in pediatric patients treated for craniopharyngioma at a referral center in the East Coast states of Peninsular Malaysia. Methodology A retrospective review of medical records of children aged 17 years and below who had been treated for craniopharyngioma in Hospital Universiti Sains Malaysia from January 2014 to December 2018. The data collected included age, gender, presenting symptoms and duration, visual acuity, visual fields, color vision, light brightness, relative afferent pupillary defects, fundus examination and cranial nerves examination. The best corrected visual acuity during presentation, and after a one-year post-operative period, was documented. Records on investigations, surgical procedures, therapeutic modalities and recurrences were also reviewed. Results A total of 11 pediatric patients (22 eyes) were recruited. Fifty percent presented with optic atrophy. The mean duration of the onset of symptoms before consultation was 22.3 (24.5) months. A final best corrected visual acuity of 6/12 (20/40) or better was observed in 50% of the patients. There was a statistically significant association between presenting visual acuity, optic nerve function and visual field defects, and the final visual outcome. Conclusions Visual presentations in our study were fairly similar to previous reported studies. One-third presented late with permanent visual loss. Almost half had significant visual impairment after one-year post-operative period. Significant associations were observed between presenting visual acuity, duration of symptoms, impairment of optic nerve function tests, and visual field defects during presentation, and final visual acuity at one year after treatment.

RESUMO

Purpose To describe the demographics, indications, clinical outcomes and survival rate of penetrating keratoplasty in Malaysian children living in a suburban area, and discuss the literature on paediatric penetrating keratoplasty. Methodology A retrospective review of medical records was performed on children younger than 17 years of age who had undergone penetrating keratoplasty in Hospital Universiti Sains Malaysia from January 2008 to December 2017. We recorded demographic data, presenting visual acuity, indications, final visual acuity, and graft survival at 12 months into the postoperative period. Results Sixteen eyes of 14 children had penetrating keratoplasty. Mean age was 7.8 ± 5.9 years. Both genders were equally affected. The main indications were infective keratitis (56.25%), congenital corneal opacity (18.75%) and trauma (12.50%). There were 62.50% of patients who had a preoperative visual acuity worse than 6/60. Fifty percent had other combined procedures during the surgery, including lens aspiration, peripheral iridectomy, pupilloplasty and glaucoma tube implant. Best corrected visual acuity of 6/12 or better was achieved in 18.75% of patients. A hazy graft was noted in 68.75% of patients, and was attributed to graft rejection, glaucoma and graft failure. There was a statistically significant association between the presence of vascularized cornea, intraocular inflammation and combined surgery with survival rate of the graft at one-year postoperative period (p < 0.05). Conclusions Infective keratitis is the main indication for penetrating keratoplasty in our pediatric patients. Good visual outcome was documented in a small percentage of the patients. Amblyopia and hazy graft were the main barriers to success in this group of patients. Vascularized cornea, inflammation and combined surgery had significantly affected the survival rate of the grafts in our series.

RESUMO

INTRODUCTION: The management of orbital abscesses in neonates and infants is very challenging. Surgical drainage of the abscess is aimed at removing the pus and preventing blindness. We describe a case of orbital abscess in an infant that was caused by methicillin-resistant Staphylococcus aureus and that was successfully drained with image-guided endoscopic surgery. PRESENTATION OF CASE: A 39-day-old infant presented with progressive right maxillary swelling complicated by methicillin-resistant Staphylococcus aureus orbital abscess. Tooth bud abscess was the most likely primary cause and a combination of intravenous antibiotics was initially prescribed. The collection of intra-orbital pus was removed using image-guided system-aided endoscopic surgical drainage. DISCUSSION: Prompt diagnosis and management are very crucial. Endoscopic drainage of these abscesses in children has been described. Image-guided drainage of the orbital abscess is a newer technique that has been reported in a teenager and in adult patients. This is the first reported case of endoscopic orbital drainage surgery in an infant. The procedure was performed successfully. This approach provides for better identification of the anatomical structures in a very young patient. Injuries to the medial rectus, globe and optic nerve can be avoided with this technique. CONCLUSION: Aggressive management of orbital abscesses in infants is mandatory. Image-guided endoscopic orbital drainage offers precise visualization and a safer technique in a relatively smaller orbit.

RESUMO

INTRODUCTION: Hyphema and orbital apex syndrome occurring concurrently in a patient with herpes zoster ophthalmicus have not been reported previously. We present a case with these unique findings and discuss the pathogenesis of these conditions and their management. PRESENTATION OF CASE: A 59-year-old Malay lady with underlying diabetes mellitus presented with manifestations of zoster ophthalmicus in the left eye. Two weeks later, she developed total hyphema, and complete ophthalmoplegia suggestive of orbital apex syndrome. She was treated with combination of intravenous acyclovir and oral corticosteroids, and regained full recovery of ocular motility. Total hyphema persisted, and she required surgical intervention. DISCUSSION: Hyphema is postulated to occur due to an immune vasculitis affecting the iris vessels. Orbital apex syndrome is probably due to an occlusive vasculitis affecting the vasculature of the extraocular muscles and optic nerve, resulting from a direct invasion by varicella zoster virus or infiltration of perivascular inflammatory cells. Magnetic Resonance Imaging of the brain is essential to exclude possibility of local causes at the orbital apex area. CONCLUSION: Herpes zoster ophthalmicus is an uncommon ocular presentation. Managing two concurrent complications; persistent total hyphema and orbital apex syndrome is a challenging clinical situation. Early diagnosis and prompt treatment are essential to prevent potential blinding situation.

RESUMO

Myositis is a rare unknown inflammatory disorder of the skeletal muscle tissue. Generalized inflammatory myopathies, polymyositis, and dermatomyositis have been reported during pregnancy. Isolated orbital myositis in pregnancy has not been previously described in the literature. The authors report a case of left isolated orbital myositis in a primigravida at 38 weeks gestation affecting the patient's left lateral rectus muscle. MRI of the orbit was consistent with the diagnosis. She showed remarkable clinical improvement with oral corticosteroids therapy.

RESUMO

A decrease in the anterior capsule opening after cataract surgery has been observed in eyes with weakened lens zonules. It commonly occurs in diabetes mellitus, uveitis, pseudoexfoliation syndrome, high myopia, and elderly patients. Herein, we report the case of a middle-aged man with advanced retinitis pigmentosa who developed a rapid contraction of the anterior capsule after an uneventful phacoemulsification surgery that resulted in severe visual loss during the early postoperative period.
