Amyloidosis is a disorder characterized by the deposition of insoluble abnormal proteins in the extracellular space. It may occur as a localized lesion or as a systemic disease involving multiple organs and systems. Localized conjunctival amyloidosis is rare and is less frequently associated with systemic involvement. Although amyloidosis itself is a benign lesion involvement of multiple organs and systems is associated with poor prognosis. Diagnosis of amyloidosis is made on biopsy specimens with Congo red staining for the appearance of apple-green birefringence under polarized light microscopy...

BACKGROUND: Human papillomavirus (HPV) is a causative agent for intraepithelial squamous neoplasms, particularly on mucosal surfaces. HPV has a well-established association with squamous cell carcinoma (SCC) of the oropharynx and genital tract, and recent studies suggest a potential role in ocular and periocular squamous neoplasms. Multiple high-risk HPV genotypes are associated with histologically similar squamous neoplasms, and some HPV genotypes have been differentially associated with high- or low-grade lesions...

We present a cost-effective and portable platform based on contact lenses for non-invasively detecting Staphylococcus aureus, which is part of the human ocular microbiome and resides on the cornea and conjunctiva. Using Staphylococcus aureus-specific antibodies and a surface chemistry protocol that is compatible with human tear, contact lenses are designed to specifically capture Staphylococcus aureus. After the bacteria capture on the lens, and right before its imaging, the captured bacteria are tagged with surface-functionalized polystyrene microparticles...

An 18-year-old American Miniature Horse mare was presented with a complaint of a scleral swelling affecting the right eye and a history of suspected trauma 6 weeks prior to evaluation. Clinical findings included severe blepharospasm, a bulbous swelling of the dorsotemporal bulbar conjunctiva, and phthisis bulbi. Ocular ultrasound was recommended but declined. Enucleation was elected for the blind, painful eye and was performed standing. Gross and histopathologic examinations of the globe were consistent with extrusion of the lens to the episcleral space, which is classified as a traumatic phacocele when associated with naturally occurring trauma...

Purpose: To present the case of a 12-year-old female with an epibulbar osseous choristoma. Observations: The patient presented with right-sided conjunctival mass, which caused her discomfort. Slit lamp examination revealed a 5×5-mm, firm nodule in the superotemporal quadrant of the bulbar conjunctiva. The nodule had feeder vessels, adhered firmly to the sclera, and lacked signs of malignancy. The patient underwent excisional biopsy under general anesthesia. During this procedure, great care was taken to avoid perforation of the globe...

Dry eye disease is a chronic condition of the corneal surface marked by persistent symptoms of irritation or burning that can cause inflammatory damage to the cornea and conjunctiva if untreated. Common risk factors for this syndrome include advancing age, female sex, low humidity environments, systemic medications, and autoimmune disorders. Treatments to relieve symptoms include tear replacement, humidification, improved nutrition, and anti-inflammatory ocular agents. Home healthcare nurses can identify signs and symptoms of dry eye syndrome and initiate strategies that range from warm compresses to physician referrals for more aggressive treatment...

Conjunctivochalasis is a common cause of tear dysfunction due to the conjunctiva becoming loose and wrinkly with age. The current solutions to this disease include either surgical excision in the operating room, or thermoreduction of the loose tissue with hot wire in the clinic. We developed a near-infrared laser thermal conjunctivoplasty system. The system utilizes a 1460-nm programmable laser diode system as the light source. At this wavelength, a water absorption peak exists and the blood absorption is minimal, so the heating of redundant conjunctiva is even and there is no bleeding...

Purpose: Descemet's stripping automated endothelial keratoplasty (DSAEK) is more difficult in hypotonic eyes with filtering bleb, due to the difficulties in elevating the intraocular pressure (IOP). We report a new method that uses ophthalmic viscoelastic devices (OVDs) to achieve good graft adhesion. Case Presentation: We performed modified DSAEK surgery on 2 eyes of 2 patients, who had previously undergone a trabeculectomy. Both eyes had functioning filtering blebs; the IOP was lower than 10 mmHg without medication...
