RESUMO
Corticosteroids are crucial for treating inflammatory ocular conditions. The development of dexamethasone revolutionized targeted ocular therapy. Ozurdex, a dexamethasone implant, effectively treats various eye conditions but carries risks such as implant migration. This is a case of anterior segment migration of intravitreal dexamethasone implant, Ozurdex, in a patient with scleral fixation intraocular lens implant in whom conservative management with supine positioning and pharmacologic pupil dilation can help retain the implant back in the vitreous. Patients at high risk of Ozurdex migration should avoid its use. Educate patients on the risk of implant migration and signs of migration to present immediately to an ophthalmology emergency department to avoid corneal damage. It is essential to identify high-risk patients before considering Ozurdex migration. In some cases, conservative management can be initiated while preparing for surgical removal.
RESUMO
INTRODUCTION: Infectious Keratitis is one of the most common ocular emergencies seen by ophthalmologists. Our aim is to identify the risk factors and clinical features of Acanthamoeba Keratitis (AK). METHODS: This retrospective chart review study was conducted at King Khaled Eye Specialist Hospital, Riyadh, Saudi Arabia, and included all the microbial keratitis cases, male and female patients of all ages. The main outcome is the differentiation between various microbial keratitis types. RESULTS: We included 134 consecutive eyes of 126 persons. We had 24 cases of acanthamoeba keratitis, 22 bacterial keratitis, 24 fungal keratitis, 32 herpetic keratitis, and 32 bacterial co-infection. Contact lens wear was found in 33 eyes (24.6%). Among acanthamoeba keratitis patients, 73% were ≤ 39 years of age, and 73% were females (P <0.001). Also, in AK cases, epithelial defect was found in all cases (100%), endothelial plaques were found in 18 eyes (69.2%), 12 cases had radial keratoneuritis (46.2%), and ring infiltrate was found in 53.8% of AK cases. CONCLUSIONS: We determined the factors that increase the risk of acanthamoeba infection and the clinical characteristics that help distinguish it from other types of microbial keratitis. Our findings suggest that younger females and patients who wear contact lenses are more likely to develop acanthamoeba keratitis. The occurrence of epitheliopathy, ring infiltrate, radial keratoneuritis, and endothelial plaques indicate the possibility of acanthamoeba infection. Promoting education on wearing contact lenses is essential to reduce the risk of acanthamoeba infection, as it is the most significant risk factor for this infection.

Purpose: The study aims to assess the perception of optical spectacles use among the Ha'il region population in Saudi Arabia. Patients and Methods: A cross-sectional survey was distributed via various social media applications to the residents of the Ha'il region. An online questionnaire was designed and included informed consent and questions assessing the participants' perceptions about wearing eyeglasses, contact lenses, and general eye health. Results: 32.4% of the participants think that long-term eyeglasses wearing worsens vision, and 43% think eyeglasses wearing improves vision. 75.2% believe that long-term use of glasses could cause lifetime dependency on eyeglasses. Regarding contact lenses, 45.9% believe that long-term wearing worsens vision, and 24.1% think long-term wearing of contact lenses improves vision. 60% think long-term use of lenses causes lifetime dependency on those contact lenses. Conclusion: Our results highlighted the misconceptions among the study population regarding wearing prescribed eyeglasses and contact lenses. Thus, education programs and media are warranted to correct the misconceptions about spectacles and raise the awareness about refractive errors and treatment options.
RESUMO
Purpose: Dry eye disease (DED) is a common ocular problem that worsens patients' quality of life. This study aimed to assess DED prevalence and risk factors among medical students at the University of Tabuk. Patients and Methods: This is an analytical, cross-sectional, survey-based study. An online questionnaire was distributed by email to all medical students at the University of Tabuk. A self-administered McMonnies questionnaire was used in the assessment. Results: We included 247 medical students who completed the questionnaire. Most participants were females (71.3%) and were <25 years old (85.8%). DED prevalence rate was 18.2% (95% CI=13.61% to 23.61%). Furthermore, DED was found to be significantly associated with the presence of irritation of eyes when waking up from sleep (OR=19.315), sleeping with partially opened eyes (OR=19.105), redness and irritation of the eyes when swimming in chlorinated fresh water (OR=7.863), and having prescription eyedrops or other dry eye treatments (OR=3.083). Conclusion: Our study at the University of Tabuk found that 18.2% of medical students had dry eye disease and identified the associated risk factors. Early diagnosis and treatment are crucial to prevent complications due to the high prevalence of DED.
RESUMO
This study aimed at assessing the extent to which the general Saudi population has embraced digital health medical applications to meet their health-related needs so that the Saudi Ministry of Health and government can appropriately be guided on scaling up digital health across the country. As such, this study was guided by the question of to what extent the Saudi people use digital health mobile-based applications. This was a cross-sectional study utilizing snowballing sampling approach. Frequencies, Chi-square, and Spearman rank correlation statistics were used to offer descriptive and inferential analysis of the variables. The majority of the participants were economically able to afford smart devices that have medical apps, had at least an app on such devices, and highly regarded the benefits of the apps. Unfortunately, their understanding of how to use such apps was limited, and this posed a barrier to embracing digital health alongside difficulty downloading apps and medical ethical concerns. Although there is a willingness, extra effort is needed from the Saudi Ministry of Health and the government to promote the uptake of digital health in Saudi Arabia.
RESUMO
Sickle cell trait is considered a benign condition. Ophthalmic manifestations are infrequent but can result in significant visual deterioration. We present a case of a 33-year-old male, not known to have any medical illnesses, who presented to the ophthalmological emergency room complaining of a sudden onset of painless and profound left eye vision loss for 12 hours. The patient denied any medication use, past eye trauma, or surgery. On detailed ophthalmologic examination, the best-corrected visual acuity (BCVA) was 20/20 in the right eye and hand movement in the left eye. Dilated fundus examination of the left eye showed a central retinal artery occlusion (CRAO) with pale, white retinal swelling and a macular cherry-red spot. Fundus fluorescein angiography showed delayed arterial filling with persistently reduced macular perfusion. CRAO was diagnosed in an otherwise healthy young male. Systemic workup was negative except for protein electrophoresis, which showed sickle cell trait, and HbA1C was 7.8%. Later, atrophic macular changes with a pale optic disc were observed, and BCVA was reduced to light perception. CRAO in young patients amounts to diverse causes, which require extensive systemic workup. In addition, the concurrence of the sickle cell trait with diabetes mellitus might have a role in CRAO development.
RESUMO
Diabetes mellites (DM) is one of the most common systemic disorders in Saudi Arabia and worldwide. Diabetic retinopathy (DR) is a potentially blinding ophthalmic consequence of uncontrolled DM. The early detection of DR leads to an earlier intervention, which might be sight-saving. Our aim in this cross-sectional study is to assess patients' knowledge and practices regarding DR, and to detect the barriers for eye screening and receiving a check-up from an ophthalmologist. The study included 386 diabetic patients. One hundred and thirty-one patients (33.9%) had T1DM and 188 (48.7%) had T2DM. Most of the diabetic patients (73.3%) know that they must have an eye check-up regardless of their blood sugar level. DM was agreed to affect the retina in 80.3% of the patients, 56% of patients agree that DM complications are always symptomatic, and 84.5% know that DM could affect their eyes. The fact that blindness is a complication of diabetic retinopathy was known by 65% of the diabetic patients. A better knowledge was detected among patients older than 50 years of age (54.9%) compared to those aged less than 35 years (40.9%), which was statistically significant (p = 0.030). Additionally, 61.2% of diabetic patients who were university graduates had a significantly better knowledge in comparison to 33.3% of illiterate patients (p = 0.006). Considering the barriers to not getting one's eyes screened earlier, a lack of knowledge was reported by 38.3% of the patients, followed by lack of access to eye care (24.4%). In conclusion, there is a remarkable increase in the awareness of DR among the Saudi population. This awareness might lead to an earlier detection and management of DR.
RESUMO
OBJECTIVES: This study aimed to investigate the knowledge and attitude of the public in Saudi Arabia toward the concept of surface decontamination during the COVID-19 pandemic. METHODS: A cross-sectional, web-based study was conducted over six months, from February 2021 to July 2021. We included adult Saudi and non-Saudi males and females living in Riyadh, Saudi Arabia. Results: Six hundred and twenty-six responses from Saudi (92.7%) and non-Saudi (7.3%) participants with a median age of 24 years and interquartile range (IQR) of 21-29 years were received. Regarding knowledge level, 32.10% of the participants had good knowledge of respiratory virus transmission, and only 3.4% had good knowledge of decontamination products. Overall, 58.1% of the participants had a positive attitude toward decontamination products, and 28% had a negative attitude. Older participants, females, and participants who received their information from the Ministry of Health had higher odds of having a positive attitude toward disinfectant (OR = 1.022, 95% CI: 1.004 to 1.039, p = 0.013), (OR = 3.05, 95% CI: 2.08 to 4.47, p < 0.001), and (OR = 2.95, 95% CI: 1.44 to 6.05, p = 0.003), respectively. Conclusion: The current evidence suggests that the knowledge in the general population of Saudi Arabia is low regarding the transmission of COVID-19 infection and disinfectant products. The prevalence of using decontamination products and attitude toward it is average. Continuous awareness campaigns are required to increase the public's awareness toward such products to change the population's attitude and practice, improve the prevention, and reduce the spread of the infection and its related misconception.
RESUMO
INTRODUCTION: The hydrogel Scleral Buckle is a soft and pliable subtype of buckles which has been used to repair retinal breaks and detachments externally. This case represents an unusual late orbital complication of the implant. CASE REPORT: A 70 years old male patient presented with drooping right upper lid and eye misalignment, associated with foreign body sensation and discomfort. The patient underwent scleral buckle surgery for a rhegmatogenous retinal detachment 32 years before his presentation using a hydrogel MIRAgel® explant. Orbital imaging showed a large cystic lesion in the superolateral quadrant of the orbit indicating a fluid-filled explant. DISCUSSION: In patients who were treated with hydrogel MIRAgel® explant for retinal breaks or detachments, detailed ophthalmic history, particular past eye surgery history, and examination, orbital imaging, and good clinical documentation. Serious orbital and neurological conditions need to be ruled out carefully. CONCLUSION: Late orbital complications of hydrogel MIRAgel® explant might develop late after surgery and might represent a diagnostic challenge for ophthalmologists.
RESUMO
INTRODUCTION: The objective of this study was to assess the epidemiological characteristics, clinical features and visual outcomes of open globe eye injury (OGI) in Tabuk, Saudi Arabia. METHODS: A retrospective chart review of OGI patients who had undergone operative repair of their injuries in Tabuk, Saudi Arabia. The collected data included patients' demographics, duration between trauma and presentation and the mechanism of trauma, wound location, extent of injury, presence of intraocular foreign body, and initial and final visual acuity data. RESULTS: Sixty-three eyes of 63 patients who were admitted for traumatic globe rupture were included; 84.1% were males and 39.7% were of pediatric age. Delay in seeking medical care for > 24 h was recorded in 4.8% of patients. The most common (42.9%) mechanism was blunt trauma followed by sharp trauma (38.1%) and projectile trauma (9.5%); 55.6% had the injury in zone 1. Intraocular foreign body was reported in 9.5% of patients. Intraocular foreign bodies were significantly more common in adults (p = 0.018) compared to children. Poor visual acuity was noted in 77.8% of patients upon presentation and 60.3% on last visit. CONCLUSION: The incidence of OGI was more common in males. The most common cause of OGI was blunt injury, and half of the injuries were in zone 1. Visual outcomes are guarded for most patients with OGIs.
RESUMO
PURPOSE: This study aims to measure the knowledge levels toward retinopathy of prematurity (ROP) among pediatricians covering neonatal intensive care units (NICUs) in the major hospitals in Tabuk, Saudi Arabia. To our knowledge, this is the first report to assess the awareness level of ROP in the NICU pediatricians in the region. PATIENTS AND METHODS: This is a quantitative, non-experimental, cross-sectional, descriptive study using self-administered electronic questionnaires to assess the knowledge level among NICU pediatricians at the main hospitals of Tabuk city. We used a self-administer online validated knowledge, attitude, and practice (KAP) questionnaire. A scoring system was implemented in the data analysis, depending on the correct chosen answers on the KAP questionnaire, to present the ROP knowledge level in the participants. RESULTS: The study included 41 NICU pediatricians. Most of the participants' age exceeded 40 years (51.2%). The majority were recruited from either King Salman Military hospital (34.1%) or King Khalid hospital (31.7%). The average frequency of preterm infants seen per month exceeded 15 infants among 41.4% of the respondents. Most pediatricians recognized the important treatment modalities available for ROP (92.7%); however, only 24.4% of them could recognize that 32 weeks or less is the gestational age of the screening criteria for ROP. The overall knowledge score ranged between 4 and 10, out of a possible maximum of 12 with a mean ± SD of (6.68±1.47). The majority (75.6%) believe that the ROP treatment can successfully prevent blindness. CONCLUSION: Our study demonstrated that the NICU pediatricians have good knowledge about the treatment modalities of ROP. However, their knowledge about the inclusion criteria of ROP screening was insufficient. Thus, we highlighted the necessity of raising the awareness level and the strict application of the clinical guidelines among NICU pediatricians and healthcare workers involved in managing ROP.
RESUMO
BACKGROUND: Central serous chorioretinopathy (CSCR) is an idiopathic condition characterized by serous retinal detachment and/or retinal pigment epithelial (RPE) detachment, the condition associated with a fluid leak through the RPE into subretinal space. This article reports on an unusual case of CSCR following taking adulterated honey mixed with tadalafil powder. CASE PRESENTATION: A 38-year-old male, not known to have any medical illnesses, came to our ophthalmology clinic complaining of sudden onset of blurred central vision in the left eye for five days after taking an adulterated honey which was claimed to improve sexual performance. On taking a history, the patient denied taking any medications or past eye trauma or surgery. On detailed ophthalmologic examination, the best-corrected visual acuity (BCVA) was 20/20 in the right eye and 20/80 in the left eye. Dilated fundus examination of the right eye showed a flat retina, normal macular reflex, healthy optic nerve head and the left eye showed blunt foveal reflex with neurosensory retinal detachment at the macula and subretinal fluid. Optical coherence tomography (OCT) of the left eye showed marked macular thickening, leading to the impression of central serous chorioretinopathy (CSCR). Four weeks after stopping the adulterated honey, BCVA improved to 20/20 in the left eye, with complete resolution of subretinal fluids. CONCLUSION: Our case adds to recently reported cases of a link between tadalafil and CSCR.
RESUMO
Amblyopia is a reduced best-corrected visual acuity of one or both eyes that cannot be attributed to a structural abnormality; it is a functional reduction in the vision of an eye caused by disuse during a critical period of visual development. It is considered the leading cause of visual defects in children. With early diagnosis and treatment, children with amblyopia can significantly improve their vision. However, if it is neglected and not treated during childhood, unfortunately, it permanently decreases vision. Therefore, prevention, detection, and treatment largely depend on parents. This article explores parents' perspectives on amblyopia and routine examination of their children's eyes. A cross-sectional study used an electronic questionnaire consisting of five main sections to assess the level of awareness of amblyopia among parents. As a result, a total of 325 participants were included in our analysis. 209 (64.3%) were mothers, and 116 (35/7%) were fathers. The age groups were 35-50 years of age (61.5%), 20-34 years (23.4%), and older than 50 years (15%). Participants with a history of amblyopia numbered 23 (7.1%), and 39 had an amblyopic child (12%). A good awareness level of amblyopia among parents was found in only 10 (3%) participants, a fair awareness level in 202 (62%), and 113 (35%) participants were classified as having a poor awareness level of amblyopia. Only 13.8% of the parents took their children for yearly routine eye exams, while the majority (72%) took their children only if they had a complaint, and 14.2% took them for eye checkups only before school entry. In conclusion, parents' awareness of amblyopia in Tabuk City, KSA, was low. In addition, a limited proportion of parents reported consistently taking their children for routine eye exams. Therefore, raising awareness should be considered in public education regarding the disease.
RESUMO
PURPOSE: Assessing diabetic retinopathy (DR) risk factors and daily nutrition habits are vital for prevention. This study aims to evaluate the relationship between diet soda cans, non-nutritive sweetener consumption, and diabetic retinopathy. PATIENTS AND METHODS: A cross-sectional study was conducted among 200 patients attending a diabetes center in Tabuk City, Saudi Arabia, from September 2019 to July 2020. A structured questionnaire was used to collect patients' demographic factors, and DR risk factors including the use of diet soda, non-nutritive sweeteners, and exercise habits. Dilated fundus eye examination was done to detect any diabetic retinopathy. A blood sample was taken for measuring glycated hemoglobin to assess the degree of glycemic control. RESULTS: The participant's age was 50.74 ±13.51 years, and the duration since the diagnosis of diabetes was 9.99 ±6.97 years, body mass index was 27.28 ±4.68, and HbA1c %, 8.50 ±1.61), the patients used to consume 1.31 ±1.57 diet soda cans/week, and 1.06±1.39 artificial sweeteners/sachet/day. DR was found in 33%. Diet sugar-free carbonated soda beverage was associated with poor glycemic control and retinopathy, while non-caloric flavor consumption was associated with obesity (P-value<0.05). No association was evident regarding other factors (P-value>0.05). CONCLUSION: Diet sugar-free carbonated soda beverage was associated with higher HbA1c and retinopathy, while non-caloric flavor consumption was associated with obesity. No association was evident regarding other factors. Further larger multicenter studies are needed.
RESUMO
PURPOSE: To report the poor visual outcome of ruptured globe caused by camel bites. OBSERVATIONS: A 48-year-old camel caregiver presented to the emergency department after being bitten by a camel in the left side of his face. Ophthalmic examination revealed a superior scleral wound from 9 to 2 o'clock, about 6 mm from the limbus extending to the equator with prolapse of uveal and vitreous tissues, an opaque cornea, total hyphema, diffuse subconjunctival hemorrhage, and a lower lid laceration involving the lid margin and the nasolacrimal duct. The patient has undergone surgical repairs of ruptured globe and lid laceration, followed by retinal detachment surgery. Following these surgical interventions, the patient preserved a light perception vision with flat retina. CONCLUSION: Camel-related injuries might primarily involve the ophthalmic structures, especially in camel bites. Camel-related eye trauma might lead to poor visual and anatomical outcomes which might not improve following surgical interventions.
RESUMO
PURPOSE: The objective was to evaluate ophthalmologists' KAP toward the outbreak of the pandemic COVID-19 disease. METHODS: This cross-sectional study was conducted during the period of the global outbreak of COVID-19, between April 8 and April 18, 2020. A sample of 120 ophthalmologists was chosen by a stratified method. The online survey was used to obtain information about respondents' KAP toward COVID-19. RESULTS: The study participants included 120 ophthalmologists and ophthalmologists under training out of the targeted 163 ophthalmologists who were invited to participate, giving a response rate of 73.6%. Ophthalmology residents represent 40.8%, whereas consultants represent 32.5% of them. Nearly 40.8% of the participants were aged between 31 and 40 years. Overall, the percentage of COVID-19 knowledge score ranged between 56% and 100% with a median (interquartile range [IQR]) of 80% (76%-88%). Overall, the percentage score of attitude toward COVID-19 ranged between 13.3% and 100% with a median (IQR) of 73.3% (46.7%-88.0%). Although the safety precaution attitude toward COVID-19 was highest among ophthalmologists aged over 50 years, the difference did not reach a statistical significance. Other studied factors were not significantly associated with the score of percentage of attitude toward COVID-19. CONCLUSION: KAP among ophthalmologists in the Kingdom of Saudi Arabia toward COVID-19 are optimal. However, health education campaigns are needed to reinforce the current KAP and improve the level of understanding of the risks and prevention measures that, in turn, improve the confidence of ophthalmologists to provide the right care to their patients and protect themselves as well.
