This study aimed to review and determine the distribution of biometry components, such as axial length (AL), anterior chamber depth (ACD), and lens thickness (LT) of pre-operative cataract patient in Indonesian population. Methods: A cross-sectional study data were obtained from 2015-2018 cataract surgery at

Glaukoma adalah salah satu penyebab utama kehilangan penglihatan dan kebutaan total di dunia saat ini terutama di negara-negara Afrika dan Barat yang mempengaruhi lebih dari 60 juta orang. Peningkatan Tekanan intraokular (TIO) merupakan faktor risiko utama untuk kematian retinal ganglion cell (RGC), yang fungsinya menyampaikan informasi visual ke otak dari mata melalui saraf optik. Pengurangan TIO saat ini dicapai melalui berbagai cara, termasuk terapi obat dan intervensi bedah. Namun, tidak ada terapi yang bisa mengembalikan penglihatan pasien menjadi lebih baik oleh karena sudah terjadi kematian RGC yang luas dan tidak dapat ber-regenerasi. Oleh karena itu, stem cell dapat menjadi pilihan satu-satunya untuk mengembalikan penglihatan. Studi sebelumnya telah menunjukkan bahwa pluripotent stem cell (PSC), retinal progenitor cells (RPC) dan sel Muller dapat d...

Epidemiological data of COVID-19 in Indonesia, especially in Surabaya have not been well established yet. Purpose: This study aims to provide the COVID-19 patients profile in Surabaya City, Indonesia. Method: The study data were retrospectively collected from electrical medical records in Primasatya Husada Citra (PHC) Hospital of Surabaya, one of the referral hospitals for COVID-19 in Surabaya. Descriptive and Spearman correlation statistics were done for data analysis. Results: Between 1 July – 31 August 2020, 456 subjects were diagnosed positive for COVID-19 by real-time polymerase chain reaction and enrolled in the study. Study subjects were dominated by the group age of 21-30 (26.75%), male (60.30%), living in East Surabaya (16.22%), and mild to moderate disease severity (47.59%) according to the patient’s clinical manifestation, respiration rate, and...

Research paper thumbnail of Pre-operative intraocular pressure as a predictor of post-operative intraocular pressure after phacoemulsification in non-glaucomatous patients

Some anatomical changes in cataract patients are assumed to be factors contributing to increased intraocular pressure (IOP). The changes in IOP after cataract surgery tend to help surgeons to predict clinical outcomes. Therefore, IOP control is very important in these patients. This study aimed to determine the ocular biometric parameters and pressure-to-depth (PD) ratio associated with IOP in non-glaucomatous patients who undergo cataract surgery. MethodsA prospective study using secondary clinical data collected from 81 non-glaucomatous patients. Data were collected by examining each subject pre- and post-operatively. The changes in ocular biometry parameters and IOP were measured one week before surgery and 8 weeks after the surgery. Univariate and multivariate linear regression were performed to analyze the data. ResultsThe mean anterior chamber depth (ACD) change was 0.73 ...

Status gizi memiliki peran yang penting dalam perkembangan sistem imun seorang anak. Keadaan imun seorang anak dapat berpengaruh pada perkembangan infeksi dengue yang dideritanya. Penelitian ini bertujuan menganalisis hubungan status gizi dengan perjalanan penyakit demam berdarah dengue anak di Rumah Sakit Gotong Royong Surabaya. Penelitian ini merupakan studi observasional dengan data primer yang dilaksanakan dengan desain cross-sectional dan metode sampling total sampling. Uji korelasi Spearman’s rho dilakukan untuk mengetahui korelasi antar variabel. Delapan belas anak usia 5-14 tahun yang menderita demam berdarah dengue pada periode 6 Juni hingga 6 September 2014 diobservasi secara klinis (lama demam dan lama perbaikan skor FPS-R) dan laboratoris (derajat leukopenia, derajat trombositopenia, dan derajat hemokonsentrasi) untuk mengetahui perjalanan penyaki...

Blindness due to cataract can be prevented with cataract surgery so the vision can be corrected. Cataract surgery have huge development and now phacoemulsification is used widely. Surgically induced astigmatism is one of many tools to evaluate the success of cataract surgery. Surgically induced astigmatism will affect visual acuity. There are many factors contributing the incident of surgically induced astigmatism such as size of incision, location of incision, and pre surgery astigmatism. Objective : to analyze surgically induced astigmatism after cataract surgery with 2.75 mm temporal clear corneal incision phacoemulsification technique. Material and Methods : Cross-sectional studies has been conducted on 92 subject. Astigmatism were evaluated in every subject before and after cataract surgery. Surgically induced astigmatism were evaluated by evaluating keratometry before and after cataract surgery. Comparative statisti...
