Dhivya Ashok Kumar, Amar Agarwal
We present a giant ocular surface squamous neoplasia (OSSN) measuring approximately 20×18 mm arising from the fornix and wrapping the entire 12 clock hours of the cornea. The surgical excision was performed with preservation of the corneal surface. A 3-mm clear margin was obtained all around the mass. The histopathology confirmed as moderately differentiated squamous cell carcinoma with clear margins. The postoperative period was uneventful, and a clear cornea without a residual scar with best corrected visual acuity of 20/20 was attained...

The causes of posterior uveitis can be divided into infectious, autoimmune, or masquerade syndromes. Viral infections, a significant cause of sight-threatening ocular diseases in the posterior segment, include human herpesviruses, measles, rubella, and arboviruses such as dengue, West Nile, and chikungunya virus. Viral posterior uveitis may occur as an isolated ocular disease in congenital or acquired infections or as part of a systemic viral illness. Many viruses remain latent in the infected host with a risk of reactivation that depends on various factors, including virulence and host immunity, age, and comorbidities...

REVIEW
Roly Megaw, Pankaj Kumar Agarwal
Posner-Schlossman syndrome, or glaucomatocyclitic crisis, is a unilateral ocular condition characterized by recurrent attacks of nongranulomatous anterior uveitis and raised intraocular pressure that can result in chronic secondary glaucoma. This relatively rare disease is most likely the result of recurrent cytomegalovirus infection and affects predominantly middle-aged males. Diagnosis is largely clinical, with aqueous and blood sampling aiding the identification of any underlying infectious cause. Successful disease management is often achieved by topical treatment, although systemic therapy and even surgical intervention may be required...

OBJECTIVES: Current international guidelines for ocular radiation exposure suggest a threshold of 20 millisieverts (mSv)/year. Although endoscopists wear lead aprons, use of protective eye wear is optional. This study was conducted to analyze the lens radiation exposure during endoscopic retrograde cholangiopancreatography (ERCP) for endoscopists to determine the time of fluoroscopy needed to warrant using lens protection during ERCP. METHODS: ERCP patients were prospectively enrolled...

Primary malignant melanoma of the vagina is an extremely uncommon malignancy comprising of less than 10% malignancies of the female genital tract and 0.3% of all melanomas. Melanoblasts are neural crest derivatives and are notorious for causing primary cutaneous neoplasms. However, they involve virtually every organ of the body including eye, intestines and ocular mucosa, probably due to aberrancies in cell migration. Vagina is a rare site and primary melanoma of the vagina occurs in postmenopausal women with vaginal discharge, bleeding, or mass as common presenting complaints...

Infectious endophthalmitis is an important cause of vision loss worldwide. This entity most often occurs as a complication of intraocular surgery especially following cataract surgery or intravitreal injection. Endophthalmitis is regarded as a serious complication following ocular surgery and the final visual outcome is fundamentally contingent on timely recognition and intervention. Intravitreal and oral antibiotics in combination with pars plana vitrectomy or vitreous aspiration remain the mainstay in the management of endophthalmitis...

Intraocular tuberculosis presents a diagnostic challenge because of its protean clinical manifestations. Thus, it becomes imperative to distinguish chorioretinal inflammation due to tuberculosis from other infectious as well as non-infectious posterior uveitis since the clinical manifestations of these entities may be quite similar. With advancing technology, a number of novel imaging modalities are available today that enable in vivo near-histologic assessment of the chorioretinal tissue, greatly aiding the clinician in establishing a diagnosis and monitoring the therapeutic response of tubercular lesions...
