1. Science behind Multifocal Intraocular Lens (MFIOL) Multifocal intraocular lenses are IOLs which can separate incoming light into two or more foci, thus resulting in multiple coexisting retinal images. At any given point, only one of the images (distance, intermediate or near) is the sharpest, and hence selected by the brain for visualisation. This concept is known as simultaneous vision. The vi...Read More
Ten Things You Should Know about 3D Viewing System in Ophthalmology
1. Evolution of this latest state of the art technology in ophthalmology: Three-dimensional (3D) display systems were first developed for aircraft and military use. The term “heads-up surgery” derived from the so-called “head-up display”, a display system first used in aircraft flight decks that projects an image into the normal field of view. This display system allows visualization in a “heads-u...Read More
Ten Pearls for Descemet's Membrane Detachment Repair
1. Embryology Understanding the embryological development of the cornea helps us appreciate the reasons for a Descemet's membrane (DM) detachment during surgery. After the lens vesicle separates from the surface epithelium, a wave of mesenchyme forms the primary corneal stroma. A second wave then forms the endothelium, which secretes the DM. The DM, hence, has a potential plane of separation f...Read More
Herpetic Eye Disease Study: All You Should Know
Herpes simplex virus (HSV) keratitis is the leading cause of corneal blindness in developed as well as developing countries. The ocular disease affects approximately 10 million people worldwide. Herpes viruses are a group of double-stranded DNA viruses with three subfamilies: alpha-, beta- and gamma- herpes viruses. HSV-1, HSV-2, and varicella-zoster virus (VZV) belong to the alpha-subfamily. HSV ...Read More
Ten Pearls to Write a Case Report
A thorough and detailed analysis of a single patient history, clinical presentation, course, and outcomes often helps in improving our understanding of the pathophysiological mechanisms of disease. However, at times, there are certain nuances in every patient that cannot be explained by large dataset-based manuscripts, where there is every chance that several minor, but relevant aspects can be ign...Read More
Ten Pearls for Corneal Scrapping
The management of microbial keratitis requires corneal scraping material for smear and culture. Scraping is a superficial keratectomy procedure to procure samples from central infiltrates or any infiltrate more than 2 mm in size. Stain/ wet mount gives a rapid clue to the diagnosis to initiate appropriate therapy. Inoculation of the sample on culture media help identify the offending organism and ...Read More
Ten Tips for Managing a Case of Postoperative Endophthalmitis
1. Suspect : Any unusual post-operative reaction ( out of proportion to surgical trauma ) should be suspected for Endophthalmitis. 2. Differentiate from TASS : All unusual post-operative reactions may not be infective; Pointers towards Toxic Anterior Segment Syndrome could include: Early onset of Limbus to limbus corneal edema with good fundus glow and no exudates in the vitreous cavity. The prese...Read More
Ten Pearls for Eyelid Tear Management
1. Key Points Eyelid injuries may be associated with ocular, orbital, and even intracranial injuries hence always rule out associated systemic trauma, occult globe injuries, or traumatic optic neuropathy. Globe involvement has been reported to be around 61% with eyelid injuries. Management of intra-ocular or systemic injuries takes precedence. The presence of orbital fat in the wound indicates the...Read More
Ten Tenets One Should know on Conjunctival Hooding
Ocular surface anatomy The ocular surface, in a strict sense, consists of the cornea and its major support tissue, the conjunctiva. In a wider anatomical, embryological, and also functional sense, the ocular mucosal adnexa (i.e. the lacrimal gland and the lacrimal drainage system) also belong to the ocular surface. The ocular surface occupies approximately 2.2 cm2 of the human body surface area [1...Read More
