Pole to Pole Intraocular Transit of Tarantula Hairs—An Intriguing Cause of Red Eye

This intriguing case report provides novel images and a description of the anterior and rarer posterior segment findings seen in ocular inflammation associated with tarantula spider hair exposure. We present an interventional case report of a 9-year-old boy who presented with a red, sore eye. Slit lamp examination revealed right eye injection, multiple small hairs at differing levels of the cornea with associated opacities and inflammation within the anterior and posterior segments of the eye. Only after detailed and repeated questioning did the aetiology become apparent. Conservative management in the form of topical steroid and antibiotics was commenced and he did well with no obvious sequelae in the medium term. Healthcare personnel (and indeed pet shop owners, arachnid enthusiasts and even parents) should be aware of the potential ocular complications of tarantula hair exposure and clinicians should perhaps specifically ask about pet-keeping when presented with an unusual red eye.

A case report on a 49-year-old female with diagnoses of ocular hypertension in her left eye (LE) treated with 250 mg/day acetazolamide for 2 years. During the slit-lamp examination, complete occlusion of both iridocorneal angles was detected. Intraocular pressure (IOP) was 10 and 35 mmHg in the right eye and LE, respectively. Phacotrabeculectomy was performed in the LE. After 1 month of the procedure, the patient developed a slowly progressive miopization from −1 to −3 diopters (D) the following months. Approximately 3 months after surgery, the patient developed an episode of acute pain, athalamia, and IOP 45 mmHg in her LE. Late-onset malignant glaucoma was suspected and the patient was treated with topical hypotensive and cycloplegic agent until a prompt vitrectomy was performed. Deepening of the anterior chamber and restoration of IOP to normal range was obtained after surgery.

Purpose: The aim of this article is to report a case of lacrimal caruncle nevus with papilloma. Methods: This is a case report of a 39-year-old female with a progressively enlarging pigmented lesion on the left lacrimal caruncle. She had been aware of a raised whitish wart on the top of this pigmented lesion for several months before her initial visit. Slit lamp examination revealed a papillomatous lesion over a well-circumscribed, pigmented lesion on the left lacrimal caruncle. Results: The histopathological examination of the excised tumor disclosed 2 characteristic findings, which include nests of nevus cells within the dermis and papillomatous structures which had fibrovascular cores overlying squamous cell epithelia with variable levels of acanthosis. The findings were consistent with an intradermal nevus and a papilloma arising from the conjunctival epithelium of the nevus. Conclusion: This is the first case report of a lacrimal caruncle nevus with papilloma. The clinical history and pathological findings of this case underscore the fact that an intradermal nevus primarily occurred on the lacrimal caruncle, after which a papilloma arose from the epithelium of the nevus as a consequence of human papillomavirus autoinoculation.

Purpose: To report corneal toxicity following intentional inoculation of the juice of crushed leaves of datura (Datura Inoxia). Case Report: A 70-year-old male presented with diminished vision, redness, watering, and photophobia in his right eye one day before his presentation. The patient had instilled the juice of datura leaves in his right eye to treat his ocular problems. Slit lamp examination revealed mild conjunctival and circumcorneal congestion, corneal edema, and folds in Descemet’s membrane. The left eye was pseudophakic with an otherwise unremarkable examination. The patient was treated with dexamethasone, cycloplegics, and lubricants. The cornea did not sufficiently recover after one month of treatment leaving him with permanent corneal decompensation that required a referral for keratoplasty. The patient was followed up for six months. We hypothesize damage to the corneal endothelial Na+/K+-ATPase pump by tropane alkaloids as a cause for corneal decompensation. Conclusion: Awareness about toxicity of this commonly grown plant in the tropics and subtropics is essential in order to avoid blindness due to accidental or deliberate use.

Congenital Heart Anomaly

Case Report. A 15-year-old boy presented to the Fatih Sultan Mehmet Education and Research Hospital with the complain of bilateral vision blurring associated with severe glare and photophobia. On ophthalmological examination, uncorrected visual acuity was 20/200 in the right eye and 20/100 in the left eye, and there was no improvement with pinhole testing. The slit-lamp examination showed persistent pupillary membranes (PPM) in both eyes. According to the history obtained from his parents, he had received cardiac surgery for tetralogy of Fallot (TOF) 8 years ago.Conclusion. This patient is unique because this is the first reported case of bilateral PPM with congenital heart anomaly in the literature. Bilaterality of the eye anomaly strengthens the possibility of an uncommon association between PPM and TOF, rather than local failure in embryonic development.

Slit lamp examination is an important component of a pediatric eye exam. The slit lamp instrument, also known as a biomicroscope, is used to provide a stereoscopic magnified view of the ocular structures. The slit lamp facilitates the examination of both the anterior segment as well as the posterior segment of the eyes. For posterior segment examination, handheld lenses are used in conjunction with the slit lamp. Different tools and examination techniques are often needed to examine infants, toddlers, and other pediatric patients who cannot be positioned in the slit lamp. This chapter discusses the techniques and equipment used to facilitate the ocular health examination, including anterior segment structures, posterior segment structures, and intraocular pressure measurements in the pediatric population.

Objective: To present a method of indocyanine green angiography (IA) and fluorescein sodium angiography (FA) for simultaneously evaluating anterior segment neovascularization and fundus abnormality.Participants: We examined 19 eyes of 19 patients suspected of having neovascularization in the anterior segment of the eye. Seventeen eyes of 17 patients suffered from proliferative diabetic retinopathy, and two eyes of 2 patients had central retinal vein occlusion.Methods: Using Heidelberg Retina Angiograph 2 (HRA2), we performed angiography of the anterior and posterior segment of the eye.Results: Of the 19 cases, anterior segment neovascularization was clearly observed with slit-lamp examination and gonioscopy in 12 eyes (63.1%). However, anterior segment neovascularization was detected by HRA2 angiography in 18 eyes (94.7%). Posterior segment angiography revealed non-perfusion area in 16 eyes (84.2%) and retinal neovascularization in 10 eyes (52.6%). In one case, the posterior segment findings were not obtained due to vitreous hemorrhaging.Conclusion: Simultaneous anterior and posterior segment HRA2 angiography using indocyanine green andfluorescein sodium is a useful technique for detecting neovascularization in the anterior segment of the eye as well as non-perfusion areas and neovascularization of the retina.

Macular Corneal Dystrophy

Abstract Background Corneal dystrophies are a group of rare, inherited disorders that are usually bilateral, symmetric, slowly progressive, and not related to environmental or systemic factors. The majority of publications present the advanced form of the disease with a typical clinical demonstration. The initial signs and symptoms of different epithelial and stromal corneal dystrophies are not specific; therefore, it is very important to establish the early characteristic corneal features of these disorders that could guide the diagnostic process. Case presentation The main purpose of this study was to report the differential diagnosis of a pediatric patient with bilateral anterior corneal involvement suspected of corneal dystrophy. An 8-year-old male patient presented with asymptomatic, persistent, superficial, bilateral, diffuse, anterior corneal opacities. Slit lamp examination results were not specific. Despite the lack of visible stromal involvement on the slit lamp examination, corneal analysis based on confocal microscopy and optical coherence tomography revealed characteristic features of macular corneal dystrophy (MCD). The diagnosis of MCD was confirmed by CHST6 gene sequencing. The early corneal characteristic features of MCD, established based on the findings of this case report, include corneal astigmatism (not specific), diffuse corneal thinning without a pattern of corneal ectasia (specific), and characteristic features on confocal microscopy (specific), including multiple, dark, oriented striae at different corneal depths. Conclusions The clinical examination should be complemented with corneal imaging techniques, such as confocal microscopy and optical coherence tomography. In patients suspected of corneal dystrophy, genetic testing plays an important role in establishing the final diagnosis.
