OPHTHALMOLOGY PRACTICE
Interpreting automated perimetry
Ravi Thomas, Ronnie George
April-June 2001, 49(2):125-140
PMID:15884520
Visual field testing is mandatory for many ophthalmic conditions including glaucoma. The current gold standard for visual field testing is automated perimetry. In this article we familiarize the reader with the components of an automated perimetry printout. We describe a systematic approach that leads to a thorough interpretation of the printout. With the help of examples the reader should be able to learn to identify a normal field, detect the presence of a field defect, determine whether it is due to glaucoma, and establish progression, if any.

Management of vitreous haemorrhage.
S Saxena, S Jalali, L Verma, A Pathengay
April-June 2003, 51(2):189-196
PMID:12831156
Vitreous hemorrhage is one of the most common differential diagnoses for sudden painless decrease in vision. Often, it is caused by retinal vascular disorders secondary to common systemic ailments such as diabetes mellitus, systemic hypertension and haematological abnormalities. Sometimes it may be the beginning of a retinal tear and consequent retinal detachment that can be vision threatening if not operated early. This paper lays out practical guidelines for a tailored approach needed to arrive at the aetiology of vitreous haemorrhage so that appropriate, timely treatment can be planned.

Amniotic membrane transplantation: A review of current indications in the management of ophthalmic disorders
Virender S Sangwan, Sanghamitra Burman, Sushma Tejwani, Sankaranarayana Pillai Mahesh, Ramesh Murthy
July-August 2007, 55(4):251-260
DOI:10.4103/0301-4738.33036  PMID:17595472
Amniotic membrane transplantation is currently being used for a continuously widening spectrum of ophthalmic indications. It has gained widespread attention as an effective method of reconstruction of the ocular surface. Amniotic membrane has a unique combination of properties, including the facilitation of migration of epithelial cells, the reinforcement of basal cellular adhesion and the encouragement of epithelial differentiation. Its ability to modulate stromal scarring and its anti-inflammatory activity has led to its use in the treatment of ocular surface pathology as well as an adjunct to limbal stem cell grafts. Amniotic membrane transplantation has been used for reconstruction of the corneal surface in the setting of persistent epithelial defects, partial limbal stem cell deficiency, bullous keratopathy and corneoscleral ulcers. It has also been used in conjunction with limbal stem cell transplantation for total limbal stem cell deficiency. Amniotic membrane grafts have been effectively used as a conjunctival substitute for reconstruction of conjunctival defects following removal of pterygia, conjunctival lesions and symblephara. More recently, amniotic membrane has been used as a substrate for ex vivo cultivation of limbal, corneal and conjunctival epithelial cells. This article reviews the current literature on the applications of amniotic membrane transplantation and its outcome in various ophthalmic conditions.

Ocular manifestations in the Hutchinson-Gilford progeria syndrome
Shivcharan L Chandravanshi, Ashok Kumar Rawat, Prem Chand Dwivedi, Pankaj Choudhary
November-December 2011, 59(6):509-512
DOI:10.4103/0301-4738.86327  PMID:22011502
The Hutchinson-Gilford progeria (HGP) syndrome is an extremely rare genetic condition characterized by an appearance of accelerated aging in children. The word progeria is derived from the Greek word progeros meaning 'prematurely old'. It is caused by de novo dominant mutation in the LMNA gene (gene map locus 1q21.2) and characterized by growth retardation and accelerated degenerative changes of the skin, musculoskeletal and cardiovascular systems. The most common ocular manifestations are prominent eyes, loss of eyebrows and eyelashes, and lagophthalmos. In the present case some additional ocular features such as horizontal narrowing of palpebral fissure, superior sulcus deformity, upper lid retraction, upper lid lag in down gaze, poor pupillary dilatation, were noted. In this case report, a 15-year-old Indian boy with some additional ocular manifestations of the HGP syndrome is described.

Emerging pandemics show that humans are not infallible and communities need to be prepared. Coronavirus outbreak was first reported towards the end of 2019 and has now been declared a pandemic by the World Health Organization. Worldwide countries are responding differently to the virus outbreak. A delay in detection and response has been recorded in China, as well as in other major countries, which led to an overburdening of the local health systems. On the other hand, some other nations have put in place effective strategies to contain the infection and have recorded a very low number of cases since the beginning of the pandemics. Restrictive measures like social distancing, lockdown, case detection, isolation, contact tracing, and quarantine of exposed had revealed the most efficient actions to control the disease spreading. This review will help the readers to understand the difference in response by different countries and their outcomes. Based on the experience of these countries, India responded to the pandemic accordingly. Only time will tell how well India has faced the outbreak. We also suggest the future directions that the global community should take to manage and mitigate the emergency.

Posterior Capsule Opacification : A Review of the Aetiopathogenesis, Experimental and Clinical Studies and Factors for Prevention
Suresh K Pandey, David J Apple, L Werner, Anthony J Maloof, E John Milverton
April-June 2004, 52(2):99-112
PMID:15283214
Posterior capsule opacification (PCO, secondary cataract, after cataract) is a nagging postsurgical complication following extracapsular cataract surgery (ECCE) and intraocular lens (IOL) implantation. PCO should be eliminated since it has deleterious sequelae and Neodynium: Yttrium Aluminium Garnet (Nd: YAG) laser treatment often is an unnecessary financial burden on the health care system. PCO following cataract surgery could be a major problem, since patient follow-up is difficult and the Nd:YAG laser is not always available. Advances in surgical techniques, IOL designs/biomaterials have been instrumental in bringing about a gradual and unnoticed decrease in the incidence of PCO. We strongly believe that the overall incidence of PCO and hence the incidence of Nd:YAG laser posterior capsulotomy is now rapidly decreasing - from 50% in the 1980s and early 1990s to less than 10% currently. Superior tools, surgical procedures, skills and appropriate IOL designs have all helped to significantly reduce this complication. In this article, we review the aetio pathogenesis, experimental and clinical studies and propose surgical and implant-related factors for PCO prevention. Careful application and utilisation of these factors by surgeons could lead to a significant reduction is secondary cataract, the second most common cause of visual loss worldwide

Lekha Mary Abraham, Thomas Kuriakose, Viswanathan Sivanandam, Nithya Venkatesan, Ravi Thomas, Jayaprakash Muliyil
April-June 2005, 53(2):105-108
DOI:10.4103/0301-4738.16173  PMID:15976465
Aims: To evaluate the relationship between amplitude of accommodation and refractive errors in the peri-presbyopic age group. Materials and Methods: Three hundred and sixteen right eyes of 316 consecutive patients in the age group 35-50 years who attended our outpatient clinic were studied. Emmetropes, hypermetropes and myopes with best-corrected visual acuity of 6/6 J1 in both eyes were included. The amplitude of accommodation (AA) was calculated by measuring the near point of accommodation (NPA). In patients with more than 2 diopter sphere correction for distance, the NPA was also measured using appropriate soft contact lenses. Results: There was a statistically significant difference in AA between myopes and hypermetropes ( P <0.005) and between myopes and emmetropes ( P <0.005) in the 35-39 year age group. In the 40- 44 year age group, there was a significant difference in AA between emmetropes and hypermetropes ( P <0.0001), emmetropes and myopes ( P <0.01) and hypermetropes and myopes ( P <0.0001). In patients above 45 years of age there was no significant difference ( P >0.5). Conclusion: Our study showed higher amplitude of accommodation among myopes between 35 and 44 years compared to emmetropes and hypermetropes

Orbital regional anesthesia: Complications and their prevention
CM Kumar
April-June 2006, 54(2):77-84
DOI:10.4103/0301-4738.25826  PMID:16770022
Serious complications following orbital regional anesthesia are rare, but occur following both needle and blunt cannula (sub-Tenon's) techniques. Each technique of orbital regional anesthesia has its own risk/benefit profile. This article reviews the etiology, risk factors, treatment and prevention of complications of commonly used akinetic orbital blocks. Ophthalmologists and ophthalmic anesthesiologists must be prepared to deal with rare, but serious complications, that can occur with any technique of orbital regional anesthesia.

Interpretation of computed tomography imaging of the eye and orbit. A systematic approach
Milind N Naik, Kishore L Tourani, G Chandra Sekhar, Santosh G Honavar
October-December 2002, 50(4):339-353
PMID:12532506
Computed tomography (CT) has revolutionised the diagnosis and management of ocular and orbital diseases. The use of thin sections with multiplanar scanning (axial, coronal and sagittal planes) and the possibility of three-dimensional reconstruction permits thorough evaluation. To make the most of this technique, users must familiarize themselves with the pertinent CT principles and terminology. The diagnostic yield is optimal when the ophthalmologist and radiologist collaborate in the radiodiagnostic workup. In this article we describe a systematic approach to the interpretation of ocular and orbital CT scans.

Mooren's ulcer : Current concepts in management
VS Sangwan, P Zafirakis, CS Foster
January-March 1997, 45(1):7-17
PMID:9475006
Mooren's ulcer is strictly a peripheral ulcerative keratitis (PUK) with no associated scleritis. It occurs completely in absence of any diagnosable systemic disorder that could be responsible for the progressive destruction of the cornea. The aetiology of Mooren's ulcer remains uncertain. However, recent studies indicate that it is an autoimmune disease directed against a specific target molecule in the corneal stroma, probably triggered in genetically susceptible individuals by one of several possible provocateurs. Advances have been made in the management of this disease. Immunosuppressive therapy has been shown increasingly successful in patients unresponsive to conventional treatment and in bilateral progressive destructive ocular disease.

Limbal stem cell deficiency : Concept, aetiology, clinical presentation, diagnosis and management.
HS Dua, JS Saini, A Azuara-Blanco, P Gupta
April-June 2000, 48(2):83-92
PMID:11116520
Defects in renewal and repair of ocular surface as a result of limbal stem cell deficiency are now known to cause varying ocular surface morbidity including persistent photophobia, repeated and persistent surface breakdown and overt conjunctivalisation of the cornea. Ocular conditions with abnormalities of ocular surface repair include pterygium, limbal tumours, aniridia, severe scarring following burns, cicatricial pemphigoid and Stevens-Johnson Syndrome, sequelae of mustard gas exposure and Herpes simplex epithelial disease, radiation keratopathy, contact lens induced keratopathy, neuroparalytic keratitis and drug toxicity. Restoring ocular health in these eyes has traditionally been frustrating. An understanding of these intricate cell renewal and maintenance processes has spurred the evolution in recent years of new treatment methods for several blinding diseases of the anterior segment; many more exciting modalities are in the offing. However, there is inadequate awareness among ophthalmologists about the current principles of management of ocular surface disorders. The purpose of this article is to help elucidate the important principles and current treatment methods relevant to ocular surface disorders.

NS Bhatt, JG Diamond, S Jalali, T Das
April-June 1998, 46(2):67-80
PMID:9847478
Choroidal neovascular membrane in the macular area is one of the leading causes of severe visual loss. Usually a manifestation in elderly population, it is often associated with age-related macular degeneration. The current mainstay of management is early diagnosis, usually by fundus examination, aided by angiography and photocoagulation in selected cases. Various other modalities of treatment including surgery are being considered as alternate options, but with limited success. The purpose of this review is to briefly outline the current concepts and the management strategy from a clinician's viewpoint.

Finding the retinal break in rhegmatogenous retinal detachment
Sandeep Saxena, Harvey Lincoff
July-September 2001, 49(3):199-202
PMID:15887734
The development of subretinal fluid is governed by a limited number of anatomical factors and gravity. As a result, rhegmatogenous retinal detachments form in a predictable manner around the retinal break of their origin. The shape of the detachments points to the position of the break. The purpose of this review is to describe the characterstic contours of subretinal fluid in rhegmatogenous retinal detachments, and to highlight some rules and methodology which can help in the detection of the retinal break in phakic, psuedophakic and recurrent retinal detachments.
