DCR: When You Start,Do It Right !!
Introduction: Dacryocystorhinostomy (DCR) is a procedure wherein an alternate passage is created between the lacrimal sac and nasal mucosa through a bony ostium, bypassing the normal lacrimal pathway. Indications: 1. Persistent congenital lacrimal duct obstruction unresponsive to conservative management. 2. Primary acquired nasolacrimal duct obstruction (PANDO). 3. Secondary acquired nasolacrimal ...Read More
Primary Angle Closure Glaucoma
Primary Angle Closure Glaucoma is a condition in which elevation of intraocular pressure (IOP) occurs as a result of obstruction of aqueous outflow by partial or complete closure of angle by the peripheral iris. I. Classical Classification: Prodromal Stage Stage of constant instability Acute Congestive Stage Chronic Angle Closure Stage Absolute Stage II. Newer Classification: Recommended by the Am...Read More
Newer Imaging Technology in Glaucoma
Clinical examination of the disc has been the basis of disc and nerve fibre layer evaluation for ages but it is marred by its subjectivity and non-reproducibility, in the diagnosis and detection of glaucoma. Though visual field changes give concrete and reproducible evidence of glaucomatous changes, it becomes manifest only after considerable damage has occurred to the retinal ganglion cells(RGCs)...Read More
Intravitreal Injections -technique and tips
Intravitreal injections involve injecting therapeutic agents (drugs/air/gases) inside the vitreous cavity through pars plana under aseptic precautions Surgical anatomy Site of injection: Pars plana Ciliary body: Consists of two parts a) anterior pars plicata b) posterior pars plana Pars plicata Circumferential zone 2.5mm in anteroposterior diameter Pars plana Varies in anteroposterior diameter nas...Read More
Development of the lacrimal secretory apparatus: The lacrimal gland develops from solid ectodermal buds in the anterior superolateral part of the orbit. The gland does not start functioning fully until approximately 6 weeks after birth. Newborn infants do not produce tears while crying. Development of the lacrimal excretory system: The Nasolacrimal duct opens in the inferior meatus of the nose. Fa...Read More
Blepharoptosis refers to the inferodisplacement or drooping of the upper eyelids.The condition can be congenital associated with the presence of a dystrophic levator muscle or acquired due to a myogenic, neurogenic, mechanical, aponeurotic or traumatic cause. We aim to provide certain general guidelines to the management of a patient with ptosis. In assessment of long case of ptosis the clinical e...Read More
Medical Management of Glaucoma
Introduction The primary goal in the treatment of glaucoma is to prevent or retard the loss of visual function caused by damage to the optic nerve. Our therapeutic approaches, however, are currently limited to reducing IOP. This approach of lowering a potentially harmful pressure will apply to patients with documented optic nerve damage and visual field loss as well as those with elevated IOP or o...Read More
Do you Know !! The eye muscles are the most active muscles in the whole body. The external muscles that move ht eyes are the strongest muscles in the human body for the job that they have to do. They are 100 times powerful than they need to be. Eyes are composed of more than two million working parts. The eye can process 36,000 bits of information every hour. A normal lifespan will bring you almos...Read More
In recent times, eyelid injuries are on the rise primarily because of the increasing incidence of road traffic accidents, industrial mishaps and intentional assaults on the human body. Injury to the eyelids, lacrimal system or orbital wall may be isolated or may occur in association with mid facial injuries. History A precise history is essential to assess the severity of the injury. In some cases...Read More
Scientific Writing: Common Pitfalls & How to Avoid Them
The preceding chapters have given us a fair idea of how to go about writing an original manuscript for publication: the why, the what, and the how of manuscript writing. We have been primed with inspiration, research tools, and the nitty-gritty of techniques to carve out an original contribution to science from the banalities of repetitious clinical routines. But before we jump headlong into the u...Read More
