Anterior segment migration of intravitreal dexamethasone implant in a patient with scleral fixation intraocular lens implant: a case report.

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.

Prevalence and Risk Factors for Symptomatic Dry Eye Disease Based on McMonnies Questionnaire Among Medical Students, Saudi Arabia; a Cross-Sectional Study.

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.

Retinopathy of Prematurity as Multidisciplinary Approach, a Pediatricians Standpoint, and Practice.

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.

Central Serous Chorioretinopathy Following Oral Use of Adulterated Honey Mixed with Tadalafil: A Case Report.

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.

Poor Outcome in Camel-Related Eye Trauma with Ruptured Globe.

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.

Evaluation of Knowledge, Attitude, and Practices toward the Outbreak Pandemic (COVID-19) Virus Disease among Ophthalmologists: A Cross-Sectional Study.

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.
