Authors: Yuneta Ressa , Sidik M , Nusanti Syntia , Pandelaki Jacub 
Published: January 2024

Background: Carotid-cavernous fistula (CCF) is an abnormal communication between the carotid arterial system and the cavernous sinus. It can manifest as proptosis, bruit, corkscrew appearance or other signs. The aims of this study were to evaluate the clinical characteristics and result of CCF therapy.Methods: This is a retrospective study which evaluated the clinical characteristic, outcome of therapy and complications after embolization in CCF patient confirmed by digital subtraction angiography (DSA) from January 2012 to December 2014.Results: Twenty-three patients, 16 male and 7 female, were diagnosed as CCF. Mean age was 26Â±10.5 years old. The most common etiology was trauma (91.3%) with onset ranging from immediately to 17 months after trauma. The frequent ocular manifestations were proptosis, bruit, and conjunctival abnormalities. Other ocular signs were ophthalmoplegia, secondary glaucoma, abnormalities of posterior segment, and decrease of visual acuity. Seventy-eight percent patient was type A CCF. Fifteen patients underwent embolization, 3 patients couldnâ€™t be embolized then treated by manual carotid compression, 5 patients were still waiting for schedule of embolization. Clinical signs of 63% patients were improved in 1 week after embolization. After several months, 2 patients with carotid compression was improved and 1 patient had persistent signs. Complications of embolization include transient sensoric aphasia (1 pasien) and central retinal vein occlusion (2 patients).Conclusion: Clinical characteristics of CCF in this study were not different with previous descriptive studies and most cases showed improvement in clinical signs after therapy.

Authors: Setyowati Reny , Goenawan Kristian , Prawiroranu Suhardjo 
Published: January 2024

Objective: Severe corneal ulcer requires immediate intensive topical antibiotics, although potentially toxic to corneal epithelium and may contribute for prolonged corneal epithelial defect. Fresh-amniotic membrane transplantation (F-AMT) could act as an adjuvant therapy that counterbalances the epithelial toxicity effect and exerting antimicrobial actions. This study evaluates the clinical improvement and factors associated with the success rate of F-AMT using suturing technique.
Methods: This was a retrospective cohort study of 28 patients (28 eyes) conducted at Dr Sardjito General Hospital, Yogyakarta. Inclusion criteria were patients with severe corneal ulcer unresponsive to conventional medical treatment who underwent multilayer F-AMT using suturing technique. Clinical improvement such as hypopyon, size of the corneal defect, and antibiotic medication were evaluated. Results: Corneal epithelial healing was effectively restored at 25 days post F-AMT. There were statistically significant difference in patientâ€™s blepharospasm (p= 0,00) and pain scale postoperative (p=0,00). There was no significant difference in patients visual acuity postoperative. Factors such as the size of the corneal defect, hypopyon, leucocyte count and neutrophil count were not correlated to epithelial healing. Failure was noted in 7 patients (25%) because of a persistent corneal defect. No patient developed major immediate postoperative complications.
Conclusion: F-AMT could be an optional adjuvant therapy with excellent results to treat non-healing severe corneal ulcer unresponsive to medical treatment by promoting epithelial healing.
Comparison of High Order Abberations Between Laser in Situ Keratomileusis (LASIK) and Refractive Lenticule Extraction (ReLEx) Surgeries
Authors: Tri Wahyu  , Susi Heryati  
Published: January 2024

Background: The needs of refractive surgery with laser to correct refractive error (myopia, hyperopia, and astigmatism) have become more demanded. Eventhough the procedures can produce expected efficacy and safety, modification in corneal surface can affect optical and visual quality, resulting in visual distortion and artefacts (glare, halo, starburst) called high order aberrations (HOA).
Objective: To report the differences of high order aberration before and after corneal ablation and refractive lenticule extraction surgery.
Methods: This is an analytical retrospective observational study which conclude 60 patients (115 eyes) who underwent laser in situ keratomileusis (LASIK), femtosecond laser-assissted laser in situ keratomileusis (FS-LASIK), femtosecond lenticule extraction (FLEx), and small-incision lenticule extraction (SMILE) during the periode of January 2017 to August 2018.
Results: Of 115 eyes, the mean of pre-operative high-order abberations were divided into four groups: LASIK was 7.27±3.85, FS-LASIK was 7.06±5.77, FLEx was 6.43±3.14, and SMILE was 3.73±1.41. Trefoil was the most common high-order abberations in pre-operative data of LASIK, FLEx, and SMILE (50.0%, 56.25%, and 51.72% respectively), while coma was mostly found in FS-LASIK (46.67%). Coma was the most common finding in first and third month after surgery. High-order aberrations between first and third month after surgery were not statistically significant different (p=0.465, p=0.889, p=0.263, and p=0.508 respectively).
Conclusion: All types of procedures of corneal ablation and refractive lenticule extractions surgeries are effective and safe in correcting refractive errors. There were no differences of post-operative high- order aberrations in all types of procedures.
CHALLENGES IN MANAGEMENT OF ENDOGENOUS ENDOPHTHALMITIS IN CHILDREN: A CASE SERIES
Authors: Parulian Eko , Edwar Lukman 
Published: January 2024

Introduction: Endophthalmitis is one of the most feared disease in ophthalmology because it can lead to loss of vision and loss of the eyeball. Endophthalmitis from endogenous cause are very rarely found in young patients without immunocompromised condition, making it difficult to be diagnosed. The lack of established guidelines for treating endogenous endophthalmitis also presents challenges for ophthalmologist. In this case series, we present our management of two pediatric patients with different presentations of endogenous endophthalmitis. We manage to salvage both of the patient’s eye ball with two different approaches.
Case Report: Our first patient was a 2-years-old boy with a chief complaint red eye since 10 days before admission. He was previously diagnosed with conjunctivitis. On admission the left eye was not very inflamed but we found hypopion and vitreous haze from ultrasound, suggestive of endophthalmitis. We gave the patient systemic antibiotics and did irrigation/aspiration of the anterior chamber. He responded well to our therapy and was discharged on tenth day of admission. 2. A 6-years-old girl with a chief complaint red painful eye since 2 days before admission. On admission, the eye was very inflamed with limited movement. The USG revealed vitreous haze suggestive of endophthalmitis. She was then given systemic and intravitreal antibiotics but showed poor response. Intravenous steroid was then given and the condition was improved. She was discharged on the fifth day.
Discussion: Our two patients came with two different presentations and responds to systemic antibiotics which was considered the mainstay of treatment in endogenous endophthalmitis. The first patient responded well with systemic and intracameral antibiotics while the second patient condition was improved only after the addition of intravenous steroid. Close observation with re-examination and re-evaluation should be done repeatedly to decide which treatment option should be administered.
Conclusion: Diagnosis and management of young patient with endogenous endophthalmitis is challenging. Thorough history taking, physical examination, laboratory examination, and microbiology examination should be done to make a prompt diagnosis and management.

Published: January 2024

Introduction: Patients with end-stage glaucoma often came with a painful blind eye. One of the managements is cyclocryotherapy (CCT) or retrobulbar chlorpromazine (CPZ). In this study, we aimed to evaluate the combined use of cyclocryotherapy and retrobulbar chlorpromazine versus cyclocryotherapy alone in reducing the intraocular pressure (IOP) and Visual Analog Scale (VAS) pain scores in end-stage glaucoma patients.
Methods: Samples were taken from patients who enrolled in the Ophthalmology Clinic of Dr. Sardjito General Hospital from October 2021 to March 2022. Samples were then divided into 2 groups, the CCT+CPZ group received the combination of cyclocryotherapy and retrobulbar chlorpromazine and the CCT group received only cyclocryotherapy. IOP and VAS pain scores pre-operation and 30th-day post-operation were examined.
Results: Thirty-three patients were included in the CCT+CPZ group and 17 patients were included in the CCT group. The mean IOP and VAS pain scores 30th-day post-operation in the CCT+CPZ group were 22.6±10.3 mmHg and 1.6±1.3 vs pre-operation 44.9±19.5 mmHg and 7.9±1.7 (p=0.000). Patients in the CCT group also show a significant reduction in both mean IOP and VAS pain scores 31.4±16 mmHg and 2.6±2.3 vs pre-operation 54.4±7.4 mmHg and 8.4±2.1 (p=0.001). Both IOP and VAS pain scores at 30th-day post-operation were significantly lower in the CCT+CPZ group compared to the CCT group (p=0.030 and p=0.013, respectively).
Conclusion: There were statistically significant differences between patients who received a combination of cyclocryotherapy and retrobulbar chlorpromazine in reducing the IOP and VAS pain score compared with patients who received only cyclocryotherapy.

Данная работа посвящена исследованию напряженного и деформированного состояний сектора толстостенной трубы из идеального жесткопластического изотропного материала, в предположении, что он закручивается вокруг оси параллельной оси z. Кручение идеально пластических стержней из изотропного, а также анизотропного материалов рассмотрено в работах [1–6]. В [3] рассмотрено также кручение сектора кругового кольца из изотропного материала. В работах [8], [9] исследовано кручение сектора кругового кольца, находящегося под действием линейного давления.
In this work, we study the stress-strain and state of the isotropic sector of a thickwalled pipe made of an ideal rigid-plastic material, under the assumption that it twists around an axis parallel to the z-axis. Torsion of ideally plastic rods made of isotropic and anisotropic material is considered in [1–7]. In [3], the torsion of a sector of a circular ring made of an isotropic material was also considered. In [8], [9], the torsion of a sector of a circular ring under the influence of linear pressure was studied.
Conservative Management of Large Post-Intubation Tracheal Laceration

Published: January 2024

ABSTRACT
Tracheal rupture is a very rare but life-threatening complication of endotracheal intubation. It is more common in women and patients older than 50 years old. Overinflation of endotracheal tube cuff and tracheal wall weakening are the most important pathogenetic mechanisms. Laceration sites are located in the posterior membranous wall in most cases. Subcutaneous and mediastinal emphysema and respiratory distress are the most common manifestations. A 55-year-old female presented with postoperative subcutaneous and mediastinal emphysema without dyspnea because of a tear in the posterior tracheal wall. The diagnosis was based on clinical manifestation, chest computer tomography scans (CT), and endoscopic findings. A conservative approach by broad-spectrum antibiotic therapy was decided because of patients’ vital signs stability and the absence of esophageal injury. The follow-up showed that there was no lesion in the posterior tracheal wall. Our case showed that in clinically stable patients without mediastinitis and with spontaneous breathing, conservative management of tracheal tears is a safe procedure.
Quadricuspid Aortic Valve: Interesting Images

Published: January 2024

ABSTRACT
The quadricuspid aortic valve is a rare congenital anomaly, usually associated with aortic regurgitation requiring surgical intervention. It may be associated with other congenital anomalies such as coronary anomalies, patent ductus arteriosus, ventricular septal defect, pulmonary stenosis, and subaortic stenosis. The diagnosis is generally established by either transthoracic or transesophageal echocardiography. Herein, we report a case of a 52-year-old woman who was diagnosed to have quadricuspid aortic valve by intraoperative transesophageal echocardiography.
