Dental caries is a prevalent chronic disease on a global scale, affecting individuals at some point in their lives. Odontogenic infections (OIs) arise from dental origins and can be caused by several pathologies, such as caries, trauma, pericoronitis, gingivitis, and iatrogenic factors. Dental caries is a prevalent chronic disease on a global scale, affecting individuals at some point in their lives. The objective of this review is to provide clinicians with information regarding uncommon yet severe complications that can arise from OIs. These complications include necrotizing fasciitis, cerebral abscess, orbital cellulitis, descending necrotizing mediastinitis, sepsis, and cavernous sinus thrombosis. The review encompasses the origin of complications, the progression of infection, as well as their diagnosis and treatment. Early diagnosis and treatment are crucial for determining the clinical course of odontogenic infections. Treatment and diagnosis of OIs in a timely manner prevent complications. Dental professionals play a critical role in the prevention and assessment of OIs, particularly those that are progressive and difficult to treat and identify. [ABSTRACT FROM AUTHOR]

A 10-year-old boy admitted for high-grade fever and pneumonia developed left preseptal and early orbital cellulitis, unresponsive to higher intravenous antibiotics. He received oseltamivir, on testing positive for H1N1 virus on the nasopharyngeal and throat swabs. There was dramatic improvement with resolution of orbital cellulitis within 24 h of starting oseltamivir. We report a very rare presentation of pediatric orbital cellulitis secondary to systemic H1N1 infection. Prompt investigations and timely treatment with oseltamivir aided in complete resolution, avoiding vision and life-threatening complications.

We report a case of 18-year-old male who has undergone phacoemulsification with implantation of toric IOL (AcrySof IQ SN6AT9) after fixation of lens capsule with Cionni′s capsular tension ring (CTR) for subluxated traumatic cataract with high astigmatism after deep anterior lamellar keratoplasty (DALK). He underwent right eye DALK for advanced keratoconus four years earlier. He had history of trauma one year later with displaced clear crystalline lens into anterior chamber and graft dehiscence, which was repaired successfully. The graft survived, but patient developed cataract with subluxated lens, for which phacoemulsification with implantation of toric IOL was done. Serial topography showed regular corneal astigmatism of -5.50 diopter (K 1 42.75 D @130°, K 2 48.25 D @40°). At 10-month follow-up, the patient has BCVA 20/30 with + 0.75 DS/- 1.75 DC @ 110°. The capsular bag is quite stable with well-centered IOL. Combination of Cionni′s ring with toric IOL could be a good option to manage such complex cases.

Introduction: Among the rhinosinusitis complications, the orbital are the most frequent ones, occurring mostly in the youngsters and children. Simultaneous complications involving the intracranial orbit and space are extremely rare, but they must be severely treated for they have a high rate of morbidity and mortality. Case report: In this work, the authors report a case of a patient who appeared to have preseptal cellulites and epidural abscess, in the form of simultaneous complications of an acute rhinosinusitis. In the patient of this case, choice was made for a clinic treatment associated with a nasosinusal endoscopic surgery and neurosurgical drainage of the intracranial abscess. CT was enough to achieve the diagnosis of this case. Final commentaries: However, it is recommended that, in cases where patients have rhinosinusitis complications, an extensive intracranial investigation needs to be deepened even when this is not so evident in the beginning. Given the polymicrobial nature of these infections, an aggressive culture-guided antibiotic therapy and a multidisciplinary follow-up significantly increase the likelihood of success.

Efficacy of intraocular lens power calculation formulas in a subset of Indian myopic population. Retrospectively reviewed 43 patients who underwent phacoemulsification with high axial length (AL) (>24.5 mm, range 24.75-32.35 mm). The power of the implanted intraocular lens (IOL) was used to calculate the predicted post-operative refractive error by four formulas: Sanders-Retzlaff-Kraff (SRK II), SRK/T, Holladay 1, and Hoffer Q. The predictive accuracy of the formulas was analyzed by comparing the difference between the "actual" and "predicted" postoperative refractive errors. Repeated measures analysis of variance (ANOVA) tests were done to have pair-wise comparisons between the formulas and P < 0.05 was considered significant. A subcategory of axial length 24.5-26.5 mm was also tested. Holladay 1, Hoffer Q and SRK/T formulas showed a slight tendency toward resultant hyperopia, with mean error of +0.24 diopters (D), +0.58 D, and +0.92 D, respectively. The Holladay 1 formula provided the best predictive result overall.

Thelaziasis is an Arthropod-born disease of the eye and adnexa caused by Thelazia callipaeda, a nematode parasite transmitted by drosophilid flies to carnivores and humans. Because of its distribution mainly confined to South Asian countries and Russia, it is commonly known as Oriental Eye worm. It is often under-reported and not been given its due clinical importance. We report first case of human Thelaziasis from Hassan District, Karnataka. Five creamy-white, translucent worms were removed from the conjunctival sac of a 74-year-old male patient. Based on morphological characters, the worms were identified as nematodes belonging to the genus Thelazia and speciation was confirmed by CDC, Atlanta as callipaeda. Rarity of the disease and its ability to cause both extra and intraocular manifestations leading to ocular morbidity is the reason for presenting this case. From the available data, this is the first case report from Karnataka, India.

We report a rare case of retained sub-retinal cortical material, which underwent spontaneous resorption. Patient presented with a left eye traumatic retinal detachment with a large retinal tear and posteriorly dislocated cataractous lens. Vitrectomy, lensectomy, silicone oil injection, and endolaser were performed. A good visual result was achieved. The report draws attention to this condition and highlights possible technique for minimizing risk of this complication in similar cases.

Orbital cellulitis is a serious, yet uncommon infection in neonates. It can result in significant sight and life threatening complications. Most commonly, it occurs secondarily as the result of a spread of infection from the sinuses. Orbital cellulitis, secondary to dental infection is rare. We hereby report a case of orbital cellulitis secondary to dental infection in a 15-day-old neonate without any systemic features.

Optic nerve head drusen (ONHD) are incidental ophthalmologic finding in the optic nerve. Patients with ONHD are often asymptomatic, but sometimes present with transient visual obscuration′s (TVO), the reported incidence of which is 8.6%. Optic nerve head drusen are of two types: Superficial; visible and deep. The deep-buried drusen mimic papilledema. Because of the varied presentation deep-buried drusen pose a diagnostic challenge to the ophthalmologists. In young patients, they are mistaken for papilledema as it is clinically difficult to detect a buried drusen in the optic nerve head, but are seen on the surface with aging as the retinal nerve fiber layer thins out. They are observed as pale yellow lesions more often located towards the poles. Clinical examination aided with diagnostic tests like computed tomography (CT) orbits and ultrasound B scan can help establish the diagnosis. Herein, we report a rare case of optic nerve head drusen in a young lady, who presented with loss of vision and clinical evaluation and investigations suggested ONHD with anterior ischemic optic neuropathy.

Infections of the ear, nose and throat are common and may threaten life. Intracranial complications may arise from infections of the ear and paranasal sinuses. Orbital complications (loss of vision) may arise from infection of the paranasal sinus. Respiratory embarrassment may result from infections of the upper aerodiogestive tract. The clinical presentation, implications and management of foreign bodies in the ear, nose and throat depend on the nature of the foreign body and the site at which it becomes lodged.
