Clinical Features, Natural Course and Surgical Techniques in the Management of Keratoglobus

Authors by: Dr.Fernandes Merle, Dr Bansal Aashish Kumar
Year of Publication: August, 2004

Keratoglobus is a rare bilateral disorder characterized by globoid protrusion and generalised thinning of the cornea, sometimes progressing to an extent that interferes with closure of the eyelids. This video illustrates such a case of keratoglobus causing mechanical lagophthalmos. Various surgical techniques including penetrating keratoplasty and lamellar corneal surgery, their indications as well as the merits and demerits in managing such a case are discussed. The surgical technique of epikeratoplasty to restore the globe contour has been demonstrated.

Lamellar Keratoplasty in Limbal Dermoid

Author by: Dr.Nibaran Gangopadhyay
Year of Publication: May 2004

Histopathologically-proven limbal dermoid patients presented between two to twenty five years, a majority concerned with cosmesis. Complete clinical evaluation was done, along with immersion B-Scan in some. Uncomplicated limbal dermoid excision was followed by lamellar keratoplasty. Satisfactory cosmesis with the maintenance of pre-existing vision was achieved in all cases. Anisometropic amblyopia associated with high astigmatism was found to be the key factor for poor visual status in these patients but good cosmesis was achieved in all these cases. This video presents the case series and the details of the surgical technique of lamellar keratoplasty especially in limbal dermoid.

Year of Publication: 2006

There are various of clinical presentations of scleral necrosis following pterygium surgery. It is a challenge for the clinician to distinguish among healing related issues, infective scleritis and immune related necrotizing scleritis. The video will present a rational approach for making the correct diagnosis and management plan.

Deep Lamellar Keratoplasty:The Modified Big Bubble Technique

Author by: Dr Rishi Swarup
Year of Publication: 2007

Deep lamellar keratoplasty (DLKP) has revolutionized the management of stromal corneal disorders such as ectasias, stromal dystrophies and scars. The ‘Big Bubble’ technique is one of the easiest and most reproducible methods of successfully baring the descemet's membrane. This animation-aided video, while describing the standard steps of the Big Bubble technique, demonstrates a modification which uses principles of both Big Bubble and manual separation techniques. This procedure which can be performed using no special instruments other than those used during standard penetrating keratoplasty significantly shortens the surgical time and minimizes the risk of complications such as descemet's membrane perforation.

No Bubble, No Trouble: The Groove & Peel Technique - A Simplified Approach to Deep Lamellar Keratoplasty

Author by: Dr Rishi Swarup
Year of Publication: 2008

Purpose: To describe alternative techniques of Deep Lamellar Keratoplasty in the event of a failed Big Bubble attempt. The Groove and Peel Technique can also be used as a primary technique of Manual Deep Lamellar dissection.

Method: The partial thickness trephination groove is progressively deepened in a spiral fashion using blunt dissection using corneal scissors till the glistening Descemet's membrane is reached. Subsequently the stromal tissue is grasped with a toothed forceps and is peeled away from the Descemet's membrane and trephination groove using traction force.

Results: Because the stretch forces are distributed over a large surface area, the entire stromal tissue can be peeled away safely without the need for introducing any instruments between the stroma and the descemet's membrane. The groove and peel technique proves to be an innovative technique of manual deep lamellar keratoplasty which is easy to master and requires no expensive instrumentation.

Ocular Rosacea: Is it Common or Commonly Overlooked in Asia?

Authors by: Dr.Nibaran Gangopadhyay
Year of Publication: May 2004

Ocular rosacea patients in the age group of 15 to 35 years presented to us, including three in the paediatric age group. Sub-optimal knowledge among ophthalmologists about acne rosacea contributes to its under-diagnosis, especially in the pigmented races. This case series shows detailed slit lamp findings of ocular changes, especially in the lids and on the cornea, for which a high index of suspicion is warranted. Dermatological consultation confirmed our diagnoses. These cases were treated successfully, with relapses in those with poor compliance. This video is of immense importance to educate ophthalmologists, especially in the Asian region.
