Cluster headache associated with oculomotor nerve palsy: A case report and review of literature.

Cluster headaches are a series of short, excruciating, and unilateral pain that happens for a short period at a time over days, weeks, or months and may awake people from sleep. It is situated behind, in, or around one eye only with possible radiation to the forehead at the same side. Cluster headache is characterized by many ocular features. However, extraocular muscle involvement is unusual in this type of headache. We present a case of chronic cluster headache associated with diplopia due to oculomotor nerve palsy in a 24-year-old man, which responded successfully to oral steroid. This presentation is rare. Therefore, ophthalmologists and neurologists should consider it in their list of a differential diagnosis. A short course of oral prednisolone has a role in the management of patients in such cases.

Bilateral Surgically Induced Necrotizing Scleritis After Pterygium Excision with Conjunctival Autograft: A Case Report.

Surgically induced necrotizing scleritis (SINS) is an immune-mediated condition that rarely occurs after ocular surgeries with a latency period of days to years. We present a case of a 49-year-old man who developed bilateral SINS two weeks after uneventful bilateral pterygium excision with conjunctival autografts. He was managed with a course of oral prednisolone, topical antibiotic ointment, topical non-steroidal anti-inflammatory drugs and lubricants, and close follow-up and rheumatological consultation.

Lichen Planus Eruption Following Oxford-AstraZeneca COVID-19 Vaccine Administration: A Case Report and Review of Literature.

Lichen planus is an autoimmune inflammatory disease that can be associated with infections, drugs, and vaccines. Recently, it has been reported to occur following mRNA-based COVID-19 vaccines, particularly the Pfizer/BioNTech vaccine. We present the first reported case of lichen planus that developed after five days following the administration of the first dose of the Oxford-AstraZeneca vaccine in a 46-year-old healthy male. The skin eruption was purple, ill-defined, non-scaly, itchy, and distributed over his face, abdomen, back, and legs. The clinical appearance of the skin eruption and histopathology confirmed the diagnosis of lichen planus. The skin lesions were not responding well to topical steroid and oral antihistamine treatment. Thus, the patient was commenced on systemic hydroxychloroquine. The mechanism of lichen planus development following the administration of COVID-19 vaccines is unclear and needs more investigations and explanations. Healthcare providers should be aware of this possible adverse reaction following the administration of different severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccines. The histopathological features of lichen planus in our case are different from those found in the lichenoid drug eruption. This finding indicates different pathophysiology that needs further investigation.

Amblyopia screening for first and second-grade children in Jordan.

AIM: To share the results of a national screening program for amblyopia in school children in the north of Jordan. METHODS: This is a prospective national screening study for amblyopia. The program rolls first and second-grade children (6 to 7 years old) in the north of Jordan. The eye examination included: best-corrected visual acuity, cover-uncover test, and cycloplegic retinoscopy. Monocular visual acuity was tested using an ETDRS visual acuity chart without correction. Moreover, children were tested with full cycloplegic refraction when the test criteria were met. Unilateral amblyopia was defined as a best-corrected visual acuity difference of 2 or more lines. In comparison, bilateral amblyopia was defined as a best-corrected visual acuity of 20/40 or worse in the best eye. RESULTS: The prevalence of amblyopia for the total sample tested (n=17 203) was 2.78% (n=479). The most common cause of amblyopia was hypermetropia (64.45%), followed by previous ocular surgeries (15.1%), myopia (10.43%), strabismus (9.39%), and congenital cataract (0.63%). CONCLUSION: This is the first and only study, identifing modifiable risk factors in Jordanian children with amblyopia. In their first couple of years of elementary education, many Jordanian children are affected by amblyopia and pass unnoticed. A more governmental effort is needed into screening programs to improve vision in the Jordanian population.

Presentation and management outcomes of Retinoblastoma among Syrian refugees in Jordan.

Purpose: The humanitarian crisis in Syria has had a profound impact on the entire region. In this study, we report the patterns of presentation and management outcomes of Syrian patients with Retinoblastoma (Rb) treated at a single tertiary cancer center in Jordan. Methods and Materials: This is a retrospective comparative study of Syrian refugees and Jordanian citizens who had Rb between 2011 and 2020. Collected data included patient demographics, presentation, tumor stage, treatment modalities, eye salvage rate, metastasis, and mortality. Results: Thirty Syrian refugees (16 (53%) had bilateral disease) and 124 Jordanian citizens (51(41%) had bilateral disease) were diagnosed with Rb during this period. The median age at diagnosis for refugees was 10 and 32 months for patients with bilateral and unilateral Rb consecutively, compared to 6 and 28 months for citizens. The median lag time between signs of disease and initiation of treatment was 3 months for refugees, compared to 1 month for citizens.Refugees were more likely to present with a more advanced stage (p=0.046). Out of 46 affected eyes in refugees; 32 (70%) eyes were group D or E, while out of 175 affected eyes among citizens; 98 (56%) eyes were group D or E. Therefore, refugees with Rb were more likely to mandate primary enucleation (48%) compared to citizens (25%) (p=0.003). However, out of 24 eyes among refugees who received conservative therapy, 15 (62%) eyes were successfully salvaged, while out of 131 affected eyes among citizens who received conservative therapy, 105 (80%) eyes were successfully salvaged (p=0.06). Two (7%) of the refugees and four (3.2%) of the citizens with Rb died from metastasis. Conclusion: Syrian refugees with Rb presented with more advanced disease due to delay in diagnosis and referral that increased the treatment burden by decreasing the chance for eye globe salvage. However, patients who received the timely intervention had a similar outcome to citizens with Rb; probably a reflection of the management of all patients at a single specialized center. We advocate for the timely referral of refugees with this rare life-threatening tumor to a specialized cancer center for the best possible outcome.

Conjunctivitis as the only sign and symptom of COVID-19: A case report and review of literature.

Similar to several viruses, coronaviruses can affect the eye and cause conjunctivitis. In addition to ocular involvement, it causes systemic manifestations, mainly respiratory symptoms. However, conjunctivitis as the only sign and symptom of coronavirus disease 2019 (COVID-19) is a rare presentation. We present a case of a 20-year-old male patient who presented with conjunctivitis for 3 days and diagnosed on the same day with COVID-19 without other manifestations. Conjunctivitis affected both eyes and resolved over 2 weeks with artificial tears only and without any ocular complications. Conjunctivitis can be the only sign and symptom of COVID-19 in some patients. Therefore, healthcare providers, particularly ophthalmologists, should take precautions when dealing with patients presenting with conjunctivitis amid the COVID-19 pandemic.
