Aravind eye care system

Aravind Eye Hospital was founded in 1976, by Dr. G. Venkataswamy, a man known to most of us simply as Dr. V. In an eleven bed hospital manned by 4 medical officers, he saw the potential for what is today, one of the largest facilities in the world for eye care. Over the years, this organization has evolved into a sophisticated system dedicated to compassionate service for sight. The Aravind Eye Care System now serves as a model, for India, and the rest of the world

Intravitreal bevacizumab (Avastin) for post laser anterior segment ischemia in aggressive posterior retinopathy of prematurity

Aggressive posterior retinopathy of prematurity (formerly known as fulminate/type II/rush disease) occurs in zone 1 or posterior zone 2. Treatment involves extensive near confluent laser ablation of a large area of avascular retina. Anterior segment ischemia is a rare complication that can occur due to injury to the long posterior ciliary arteries in the horizontal meridians during aggressive posterior laser treatment. The outcome of this rare complication is very poor. This case describes a favorable outcome of intravitreal injection of bevacizumab (Avastin) in a case of anterior segment ischemia

<i>In vivo</i> growth of retinoblastoma in a newborn infant

Retinoblastoma is a rare malignancy of the retina seen exclusively in children. It is known to cause rapid growth inside the eye and hence treatment should be started as soon as it is diagnosed. We report a case in a five-day-old infant in whom treatment (chemotherapy) was delayed by a month due to high bilirubin levels secondary to physiological jaundice, which gave us the unique opportunity to measure the growth of the tumor over a month. This case emphasizes that immediate treatment is warranted once this rare disease is diagnosed

”To Fulfill two needs with one deed”: Iris fixation of intraocular lens using four-throw pupilloplasty

Background: Pupil distortion and aphakia are common complications that follow blunt injury of the eye globe, surgical complications, and iris coloboma. Patients with these two complications complain of severe glare and photophobia even after successful intraocular lens (IOL) implantation like scleral fixation of intraocular lens (SFIOL) due to irregular pupil. To overcome this, we prefer to do pupilloplasty along with IOL implantation. Purpose: In this video, we demonstrate iris fixation of IOL using four-throw pupilloplasty; thus with one surgical technique, both pupilloplasty and iris fixation are done. Synopsis: The technique of an IOL implantation without capsular support can be challenging. There are different techniques, such as iris claw, iris fixation, and scleral fixation. Permanent mydriasis or distorted pupil can be a disabling condition, even after successful vision gain, due to photophobia. So pupilloplasty is nowadays preferred along with IOL implantation. Usually after IOL implantation, iris cerclage or pupilloplasty is done. We combined both steps with one technique: iris fixation with four-throw pupilloplasty. This technique can be used for iris coloboma with weak zonules and surgical iridectomy with aphakia cases where the pupil is irregular. Highlights: The video highlights the steps of four-throw pupilloplasty technique which is also used for fixating the IOL to the iris (iris fixation). This can give an excellent outcome in aphakia with distorted pupil using a single technique approach. Video Link: https://youtu.be/TEa54A5kg2

Large spot transpupillary thermotherapy: A quicker laser for treatment of high risk prethreshold retinopathy of prematurity - A randomized study

To compare structural and functional outcome and time efficiency between standard spot sized conventional pulsed mode diode laser and continuous mode large spot transpupillary thermotherapy (LS TTT) for treatment of high risk prethreshold retinopathy of prematurity (ROP). Ten eyes of five preterm babies having bilateral symmetrical high risk prethreshold ROP were included in this study. One eye of each baby was randomized to get either standard spot sized conventional pulsed mode diode laser or continuous mode LS TTT. There was no significant difference between structural or functional outcome in either group. The mean time taken for conventional diode laser was 20.07 minutes, while that for LS TTT was 12.3 minutes. LS TTT was 40&#x0025; more time efficient than the conventional laser. It may be better suited for the very small fragile premature infants as it is quicker than the conventional laser
