Eye donation involves removing the cornea from a deceased donor's eyes within 4-6 hours of death to provide vision to those suffering from corneal blindness or low vision. Globally, 4.6 million people experience corneal blindness due to conditions like infections, injuries, malnutrition or congenital disorders. The cornea is a thin transparent tissue at the front of the eye that can be replaced through corneal transplantation if it becomes cloudy or damaged. Donated corneas are preserved and stored by eye banks until being distributed for transplantation surgery. However, around 50% of donated corneas in India currently go unused due to factors like delayed retrieval, infection or improper storage.
The conjunctiva is a mucous membrane that lines the inner surface of the eyelids and covers the anterior sclera of the eye. It has several functions including lubricating the eye and contributing to immune surveillance. The conjunctiva consists of the palpebral, bulbar, and forniceal conjunctiva. The palpebral conjunctiva lines the inner surface of the eyelids and is subdivided into the marginal, tarsal, and orbital conjunctiva. The bulbar conjunctiva covers the anterior sclera and is separated from it by the episcleral tissue. It consists of the limbal and scleral conjunctiva. The conjunctival fornices are cul

The document summarizes various potential complications that can occur during or after cataract surgery. Preoperative complications include anxiety, nausea, allergic conjunctivitis, corneal abrasion, and issues with local anesthesia administration. Operative complications involve injuries to tissues like the iris or lens and issues with the capsulorhexis or vitreous loss. Early postoperative complications include hyphaema, iris prolapse, striate keratopathy, flat anterior chamber, uveitis, and bacterial endophthalmitis. Late postoperative issues relate to the intraocular lens. Managing complications depends on the specific issue but may involve resuturing wounds, administering medications, or additional surgeries.
The conjunctiva is a thin, semi-transparent mucous membrane that covers the inner surface of the eyelids and the outer surface of the sclera. It has three parts: the palpebral conjunctiva covers the inner eyelid, the forniceal conjunctiva is in the eyelid folds, and the bulbar conjunctiva covers the eyeball. The conjunctiva contains goblet cells that secrete mucus and has blood vessels for nutrition and lymphatic drainage. It helps maintain the tear film and prevents microbes from entering the eye.
This document discusses different types of retinal detachment. Rhegmatogenous retinal detachment is the most common type and occurs when there is a break or tear in the retina that allows fluid from the vitreous to enter the subretinal space. Tractional retinal detachment occurs when the retina is pulled away from the retinal pigment epithelium due to contraction of fibrous tissue in the vitreous. Exudative retinal detachment occurs when fluid accumulates beneath the retinal pigment epithelium due to inflammation or vascular issues. The document outlines causes, symptoms, examinations, and treatments for each type of retinal detachment.
This document discusses eye donation and its importance in India. It notes that India has 30% of global blindness, with 52 million visually impaired people and 1 in 1000 children being blind. Only 40,720 eyes are collected annually to help the 20-25,000 new cases of corneal blindness each year. The cornea can be donated within 6-8 hours of death to help restore sight to those suffering from corneal blindness. While myths exist, all religions support eye donation, only the cornea is removed in a short procedure, and anyone can pledge their eyes regardless of age, gender, medical conditions or religion. The document appeals for people to pledge and donate their eyes.

An eye bank is a nonprofit organization that retrieves, processes, stores and distributes donor corneal tissue for transplantation. Corneal blindness is a major problem in developing countries that can often be addressed through corneal transplantation, which has a high success rate. In India, the number of corneal transplants has been increasing but still does not meet the need, with over 50% of tissue coming from a few states. Eye banks are responsible for properly evaluating donor tissue through testing, examination and microscopy before distributing it to ensure safe and effective transplantation. Tissue is stored short or long-term in special nutrient media depending on preservation needs.
Eye banking and corneal transplantation 10.03.16,dr.k.n.jhaophthalmgmcri
An eye bank is a nonprofit organization that collects and distributes donated corneas for transplantation. It has medical and administrative sections. The medical section handles tissue harvesting, evaluation, preservation, and distribution following medical standards. The administrative section does public awareness, fundraising, and liaison with other groups. Corneal transplantation replaces diseased cornea with donor tissue. It can be full thickness or partial thickness. The cornea is harvested, processed, and stored before being distributed for surgery. Complications include rejection and infection. Prognosis depends on factors like eyelid abnormalities and inflammation. New techniques include lamellar keratoplasty which replaces only corneal layers.

ORIENTATION PROGRAMON EYE DONATION
1)Do you know...
There are approximately 1.2 crore blind people in India.
Of these around 20 lakh corneally blind are in need of corneal transplantation.
As against an annual requirement of 75,000 to 1,00,000 corneas, only 22,000 corneas are donated in India at present.
2)Facts about eye donation:
Eyes can be donated only after death.
Eyes must be removed within 4 - 6 hours after death.
Eyes can be removed by Registered Medical Practitioner only.
The eye bank team will remove the eyes from the home of the deceased or from a hospital.
A small quantity of blood will be drawn to rule out communicable diseases.
The identities of both the donor and the recipient are kept confidential.

Keratoplasty involves replacing diseased cornea with donor tissue. The main types are penetrating keratoplasty (PK), which replaces the full corneal thickness, and lamellar keratoplasty, which replaces only diseased layers. PK indications include scarring, infections, dystrophies and injuries. It has risks of rejection, infection, and high astigmatism. Newer techniques like deep anterior lamellar keratoplasty (DALK) and Descemet's membrane endothelial keratoplasty (DMEK) replace only diseased layers, reducing risks. Careful donor screening, surgical technique and postoperative management including steroids can reduce complications of keratoplasty.
Organ donation involves surgically removing an organ or tissue from a donor and placing it into a recipient whose organ has failed. Common organs and tissues that can be donated include the heart, kidneys, liver, pancreas, intestines, corneas, bone, heart valves, skin, and blood vessels. Eye donation specifically helps those with corneal blindness or color blindness by replacing damaged corneas to restore vision. Eye banks collect, store, and distribute donated corneas for transplantation according to legal guidelines to benefit recipients in need of sight-restoring procedures.
Eye banking involves collecting, processing, storing and distributing donated corneas for transplantation. It aims to address the growing problem of corneal blindness worldwide. An effective eye banking system requires establishing eye banks, improving tissue collection methods, providing training to medical professionals, and conducting public awareness campaigns to promote eye donation. The Sandhani National Eye Donation Society in Bangladesh operates a three-tier eye banking model with eye donation centers, eye banks, and eye banking training centers working together to combat corneal blindness in the country.

A 47-year-old male presented with a right lower eyelid lesion for two years that had recently become red and watery. Examination found a 2.7x1.6cm ulcerated, everted lesion of the right lower eyelid. Biopsy found basal cell carcinoma (BCC). The BCC was excised with frozen section-confirmed margins. This created a 30-40% full-thickness eyelid defect that was reconstructed using lateral canthotomy, Tenzel semi-circular flap, and a periosteal flap to reconstruct the posterior lamella. The periosteal flap provided a reliable, vascularized tissue that reduced the risk of ectropion and matched the native eyelid contour.
The document discusses the history and techniques of penetrating keratoplasty (PK). It notes that the first successful PK was performed in 1905. Common indications for PK include corneal opacities, dystrophies, trauma, and graft failure. The preoperative evaluation, surgical steps such as trephination and suturing, and postoperative care are described. Complications during and after PK can include perforation, bleeding, and graft rejection. Tight control of inflammation and immunosuppression are important for managing high-risk grafts.
