Superior Ophthalmic Vein Thrombosis: A Case Report in a Previously Healthy Methicillin-Resistant Staphylococcus aureus-Positive Patient.

BACKGROUND Superior ophthalmic vein thrombosis (SOVT) is a rare condition, with an incidence of 3 to 4 cases per million per year. SOVT can be classified according to the underlying etiology into septic or aseptic SOVT. We present a case of right SOVT in a previously healthy patient with a positive blood culture of methicillin-resistant Staphylococcus aureus (MRSA). CASE REPORT A previously healthy 38-year-old female patient presented with a 2-week history of worsening right-sided headache associated with photophobia, phonophobia, right-sided ear pain, and tinnitus. The best corrected visual acuity was 6/12 in the right eye and 6/6 in the left eye. Ophthalmic examination revealed right eye upper lid edema, proptosis, and diplopia in all gazes, mainly vertical. The fundus examination showed a raised hyperemic right optic disc with blurred margins. Laboratory investigations showed a positive blood culture of MRSA and elevated levels of inflammatory markers erythrocyte sedimentation rate and C-reactive protein. Orbital computed tomography examination showed periorbital and orbital cellulitis with superior ophthalmic vein thrombosis. The patient was treated successfully with antibiotics and anticoagulants. At 1-month follow-up, the patient was compliant with medications and reported full resolution of symptoms, with no visual acuity impairment. CONCLUSIONS SOVT is a challenging ophthalmic condition and can be present concurrent with orbital cellulitis or cavernous sinus thrombosis. Early imaging studies and proper management are important to prevent serious complications. Ophthalmologists need to be alerted of the importance of tailoring antibiotics based on the causative agent, to decrease the risk of therapeutic failure and microbial resistance.

Bilateral Purtscher-like retinopathy: A case report in a patient with pre-eclampsia and post intrauterine fetal demise.

INTRODUCTION: Purtscher's retinopathy is a rare ophthalmic condition with unclear pathogenesis commonly related to trauma and affecting young or middle-aged men. The annual incidence in the UK has been estimated to be 0.24 cases per million. PRESENTATION OF CASE: A 29-year-old primigravida female, previously healthy with no antenatal care, was brought to the maternal causality at 36 weeks of gestation as a case of pre-eclampsia and intrauterine fetal demise (IUFD) after a prolonged delivery attempt at home. After delivery, the patient reported bilateral vision loss. On ophthalmic examination, the best-corrected visual acuity (BCVA) was count fingers at 15 cm in both eyes. Dilated fundus exam showed scattered flame-shaped hemorrhage, multiple cotton wool Spots known as Purtscher flecken were seen in the distribution of the radial peripapillary capillary, dot and blot hemorrhage, and macular star in both eyes. The patient was treated with labetalol and magnesium sulphate for systemic control of arterial blood pressure by the obstetrics team, and managed conservatively under ophthalmic observation. Upon five months follow-up, BCVA had improved bilaterally. DISCUSSION: Visual changes have been reported in 25 % of patients with preeclampsia. Although most of these changes are transient, some rare sight-threatening eye conditions have been linked to preeclampsia namely Purtscher-like retinopathy. CONCLUSIONS: Purtscher-like retinopathy is rarely reported in preeclampsia and after childbirth. Although most of visual changes associated with preeclampsia are transient, urgent ophthalmology consultation is important to rule out serious etiologies such as Purtscher-like retinopathy.

Bilateral Retinal Vasculitis as Initial Presentation of Systemic Lupus Erythematosus with Secondary Antiphospholipid Syndrome.

BACKGROUND Systemic lupus erythematosus (SLE) is a multisystem autoimmune disease of undefined etiology with a relapsing and remitting course. Lupus retinopathy is reported in around 10% of patients with SLE; however, it is rarely the initial presenting feature of the disease. We report a unique case of bilateral retinal vasculitis as the initial presentation of SLE with secondary antiphospholipid syndrome (APS). CASE REPORT A 34-year-old man, previously healthy, presented to the eye clinic for the first time with painless reduced vision for 3 weeks. A review of systems revealed generalized fatigue, myalgia, arthralgias, and weight loss of around 10 kg in the last 3 months. On ophthalmic examination, his visual acuity was reduced bilaterally, more in the right eye. A fundus exam revealed bilateral diffuse multiple cotton-wool spots, dot and blot hemorrhage covering the posterior pole, and venous congestion and beading. In addition, there was cystoid macular edema (CME) in the fovea of both eyes, and fundus fluorescein angiography (FFA) showed bilateral areas of peripheral and macular hypo-fluorescence, multiple hyper-fluorescent knob-like aneurysmal dilatations, and vascular leaking and staining. He was diagnosed with SLE by the rheumatology team based on the clinical presentations and laboratory investigations. The patient was managed with intravenous methylprednisolone and discharged on oral prednisone with a tapering regimen. Eighteen months after, he reported significant improvement in his vision with regular follow-ups. CONCLUSIONS Ocular manifestations can be the initial presentation of SLE and can lead to serious ocular complications. Early diagnosis and proper management are essential and require cooperation between rheumatologists and ophthalmologists.

Frequency and visual outcomes of herpes simplex keratitis in a Kuwaiti tertiary referral center.

Background: Herpes simplex virus (HSV), a cause of many ocular pathologies, may affect the corneal epithelium, stroma, or endothelium, with the epithelium as the most frequently affected location. We aimed to determine the frequency and visual outcomes of HSV keratitis over a 1-year period at Farwaniya Hospital, Kuwait. Methods: This prospective observational case series included patients diagnosed with HSV keratitis who presented to the outpatient or eye casualty department between September 2022 and September 2023. Full history, demographic profile, detailed ocular and slit-lamp examinations, and visual acuity assessments were recorded prior to and after treatment. Baseline corneal sensation was assessed in the four corneal quadrants using the cotton wisp test. Results: Of the 227 patients who presented with infectious keratitis, 72 (31.7%) were diagnosed with HSV keratitis. The mean (SD) age was 45.86 (16.06) years, and 48 (66.7%) patients were male. The subtypes of HSV keratitis were endotheliitis in 27 (37.5%) patients, dendritic ulcer in 22 (30.6%), stromal keratitis with ulceration in 9 (12.5%) and without ulceration in 8 (11.1%), and geographic ulcer in 6 (8.3%). The mean baseline best-corrected distance visual acuity (BCDVA) differed significantly between the HSV keratitis subtypes (P < 0.001). Most patients (n = 70, 97.2%) had unilateral eye involvement, were treated within 1 - 2 weeks, and demonstrated improved BCDVA. Despite the improvement in BCDVA in all HSV keratitis subtypes, a significant difference in the median BCDVA remained after treatment (P < 0.001). Pairwise comparisons revealed a significantly better BCDVA after treatment in eyes with dendritic epithelial ulcers than in eyes with HSV stromal keratitis with ulceration (P = 0.003) or geographic epithelial ulcers (P = 0.005). After treatment, corneal haze and neovascularization were detected in 54 (75.0%) and 24 (33.3%) patients, respectively. Conclusions: We detected a substantial frequency of HSV keratitis in one of the governorates of Kuwait, with endotheliitis as the most common manifestation. Timely standard treatment interventions based on valid guidelines resulted in BCDVA improvement in all subtypes of HSV keratitis in our series, indicating the importance of early treatment. However, the BCDVA in eyes with dendritic epithelial ulcers remained substantially better than that in eyes with geographic epithelial ulcers or HSV stromal keratitis with ulceration, signifying the effect of the initial HSV keratitis subtype on visual outcomes. To our knowledge, this is the first study to highlight the frequency of HSV keratitis in a Kuwaiti hospital, and larger-scale research in this region is needed to further understand and manage the condition.
