Abstract

Permainan game online sangat populer pada anak sekolah. Anak sekolah dengan kebiasaan bermain game online dalam durasi yang lama rentan mengalami gangguan pada tajam penglihatan. Durasi bermain game online tanpa jeda berisiko menyebabkan kelelahan mata yang kemudian dapat menurunkan nilai visus mata. Tujuan penelitian ini untuk mengetahui hubungan antara durasi bermain game online dengan gangguan tajam penglihatan pada anak sekolah menengah pertama (SMP) di Kota Denpasar. Desain penelitian adalah observasional analitik cross-sectional dengan 62 orang siswa SMP sebagai responden. Data penelitian diperoleh dengan metode kuesioner yang diisi oleh responden dan uji nilai visus menggunakan Snellen Chart. Analisis data menggunakan program SPSS meliputi analisis univariat dan bivariat dengan uji Chi-square. Hasil statistik deskriptif karakteristik responden menunjukkan jumlah responden laki-laki sebanyak 56 orang (90,3%) dan perempuan sebanyak 6 orang (9,7%), mayoritas responden berusia 13 tahun (58,1%), responden dengan jumlah durasi bermain game online tanpa jeda per hari selama 1-3 jam sebanyak 28 orang (45,2%), 3-5 jam sebanyak 20 orang (32,3%), >5 jam sebanyak 14 orang (22,5%). Prevalensi penurunan visus didapatkan sebanyak 41 responden (66,1%); dengan 11 responden (39,3%) bermain 1-3 jam; 16 responden (80,0%) bermain 3-5 jam dan 14 responden (100,0%) bermain >5 jam. Hasil analisis bivariat dengan uji Chi-square menunjukkan nilai P sebesar 0,001 (P<0,05). Disimpulkan terdapat hubungan signifikan antara durasi bermain game online dengan gangguan tajam penglihatan. Kata Kunci: durasi bermain game online, gangguan tajam penglihatan, anak SMP

Abstract

Cerebral venous sinus thrombosis is a rare neurovascular emergency characterized by thrombotic occlusion of the dural venous sinuses. While various prothrombotic states predispose individuals to this condition, the concurrent presentation of dual hereditary Protein C and Protein S deficiency is exceptionally uncommon. This dual coagulopathy severely impairs natural anticoagulant mechanisms. We report the case of a 49-year-old male presenting with severe postural dizziness, vertigo, and bilateral lower extremity paresthesia. The patient had a history of a previous cerebral venous sinus thrombosis diagnosed in September 2023, for which he was receiving warfarin. Due to historically variable international normalized ratio levels and new symptoms, a comprehensive re-evaluation was initiated. Neuroimaging confirmed acute extension of the thrombosis involving the superior sagittal, left transverse, and left sigmoid sinuses, alongside an incidental finding of acute pan-sinusitis. To eliminate the confounding effect of warfarin on thrombophilia screening, the patient was bridged to low-molecular-weight heparin for fourteen days prior to testing. Subsequent functional assays confirmed profound deficiencies in Protein C (26 IU/dL) and Protein S (13 IU/dL). Management involved treating the regional pan-sinusitis and a strategic pharmacological transition to rivaroxaban (20 mg daily), resulting in complete clinical stabilization. In conclusion, this case underscores the necessity of rigorous methodological timing in thrombophilia testing and highlights regional inflammation as a potent acute trigger in genetically susceptible individuals. It further demonstrates the long-term viability of direct oral anticoagulants in complex dual inherited coagulopathies.
