Preparation and uses of amniotic membrane for ocular surface reconstruction.

Background: The use of human amniotic membrane transplantation is rapidly increasing for the management of various ocular surface disorders. Despite its numerous advantages, amniotic membrane is not widely available due to the lack of awareness among ophthalmologists regarding its preparation and preservation techniques.

Purpose: To provide an instructional video demonstrating the technique of harvesting, preparation, preservation of human amniotic membrane, and its uses in the management of ocular surface diseases.

Venous malformation of the conjunctiva and orbit.

A 28-year-old male presented with a large conjunctival lobulated, nonpulsatile, red vascular lesion involving a large part of the temporal quadrant of the left globe. There was no proptosis or globe displacement, but the left eye abduction was limited. T2-weighted magnetic resonance imaging scan of the brain and orbit revealed an extensive contrast-enhancing lobulated lesion in the left half of the face involving the upper lip, cheek, oral cavity, extraconal space of left orbit, and nasal cavity.

Bilateral Optic Neuritis and Facial Palsy Following COVID-19 Infection.

Cases of optic neuritis have been reported following the novel coronavirus disease 2019 (COVID-19), with most being unilateral and associated with demyelinating illness. We report a case of a 22-year-old woman who presented with sudden onset painless diminution of vision in both eyes six weeks following COVID-19 infection. She also had a history of left lower motor neuron (LMN) facial palsy immediately following COVID-19 disease that recovered fully on steroids.

Primary Intraocular Malignant Rhabdoid Tumor Mimicking Retinoblastoma in a Child.

Primary rhabdoid tumors are highly malignant, rare tumors occurring in the renal, extrarenal soft tissue or central nervous system. They have non-specific radiological features and present with several histological components that create a problem in differential diagnosis with other embryonal tumors. We report a rare case of malignant rhabdoid tumor of the retina that presented with clinical features like those of retinoblastoma.
