10 Minutes 4 Questions - Interpret OCT
Author: Dr.Avinash Pathengay
Duration: 09:39 min
Year of Publication: April 2006
Interpretation of OCT images can be faster and complete if done systematically by answering the following 4 questions.
1. How does the vitreo retinal interface appear?
2. What is the foveal contour like?
3. Is Retinal architecture altered?
4. Whether the uniformity of retinal pigment epithelial choroiocapillaries layer is disrupted?
The initial part of the video explains the normal and the various abnormalities in respect to each of the above-mentioned questions .The latter part of the video deals with practical applications of these 4 questions in the interpretation of OCT images. Viewing this video would help residents in basic interpretation and lay an insight for advanced interpretation.
Evaluation of Disc Edema

Disc edema is a common but non-specific clinical sign in neuro-ophthalmological practice and can have varied etiology, posing diagnostic dilemmas. The video highlights the clinical features that differentiate true disc edema from pseudo disc edema, and the characteristics of disc edema of different kinds of etiology that help us arrive at an early diagnosis.

Imaging modalities like angiography and ocular coherence tomography are extremely valuable in the diagnosis of choroidal neovascular membranes (CNVM). This video provides a comprehensive overview of imaging techniques in CNVM, helping the clinician decide the plan of treatment and identify recurrences during follow up.
Ophthalmic Ultrasound: B-Scan Principles and Applications
Author: Mr Vallam Srinivas
Year of Publication: August, 1998
TRT: 25:15 minutes
Echography has become an important diagnostic tool in Ophthalmology to identify ocular and orbital disorders. This video aims to acquaint beginners with the technique of performing and interpreting an ultrasound using the B-Scan instrument. It discusses the principle and properties of ultrasound, probe orientation, positioning of patient and interpretation of abnormal conditions of the vitreous (haemorrhage, foreign body...), optic nerve (glaucomatous cupping, disc coloboma,...), retina (RD versus PVD, funnel detachments, giant retinal tear,...), choroids (choroidal thickening, hemangioma,...).
Photocoagulation for Diabetic Macular Edema

Diabetic macular edema is the most common cause of vision loss in diabetics. Studies have proved that the treatment modality that uses lasers to reduce macular edema and preserve vision, is beyond compare. This video presents the various types of diabetic macular edema, the technique of photocoagulation, follow-up protocol and complications. The merits and demerits of photocoagulation for diabetic macular edema are discussed.
Retinopathy of Prematurity (ROP): Screening and Management
Authors: Dr Jalali Subhadra, Dr Bhende Jyoti, Dr Hussain Anjli
Year of Publication: Updated, April 2005
TRT: 24:25 minutes
Retinopathy of Prematurity is a preventable cause of avoidable blindness. Early screening and timely intervention prevents blindness. We present an NICU centred model for the screening and management of ROP including logistics of setting up ROP screening, pupillary dilatation, retinal examination, stages of ROP and their current treatment guidelines. This video is intended for public education of parents, paediatricians, ophthalmologists, residents, nursing staff and all other caregivers of premature babies. While this video is not meant to be an exhaustive academic account of how to treat ROP, it does provide useful insights about the care of eyes of premature babies.

Stereoscopic angiography provides a three dimensional reconstruction of the retinal and choroidal vascular architecture. Anaglyph technology has been used to reproduce the stereo ocular angiography, best visualized when viewed through red cyan spectacles. The diagnostic information obtained from stereoangiography helps in understanding the pathophysiology, planning the management and advancing the therapeutic goals of various chorioretinal disorders.
