Impact of an educational video in improving awareness of eye donation among non-medical health care workers in a tertiary health centre.

PURPOSE: To evaluate the impact of an educational video in improving awareness of eye donation among non-medical healthcare workers at a tertiary health centre. METHODS: A socio-behavioural study on knowledge and attitude towards eye donation was conducted among 373 non-medical healthcare workers through a printed semi-structured questionnaire before and after viewing a bilingual educational video. The responses were evaluated and scored. RESULTS: Pre-intervention, only 5.4% of the participants had adequate knowledge, which improved significantly to 71.6% after watching the video (P < .001). Respondents with elementary school education showed the greatest change in knowledge. Pre-intervention, 72.4% were willing to donate their eyes, which significantly increased to 89.5% after watching the video. Pre-intervention, 66.22% showed a "highly favourable" attitude, which improved to 97.86% after watching the video. CONCLUSION: The 25 min video about eye donation and eye banking significantly changed the participants' knowledge, willingness, and attitude. Hence, media-based (video) awareness platforms may be valuable for improving the general public's knowledge and attitude towards eye donation. This may help in enhancing the eye donation rate in the long term.

A complete clinical review of idiopathic macular telangiectasia.

Idiopathic macular telangiectasia refers to a disease entity characterized by telangiectasia and alteration of the juxtafoveal capillary network. It can present uniocularly or binocularly and is subdivided into three groups which have varied appearances. Group I occurs in males which is easily identifiable and has macular edema. Group II has no sex predilection and difficult to distinguish by clinical examination and often requires the need of optical coherence tomography and angiographic modalities. Group III is not so common with its progressive nature and associated with neurological diseases. This article is aimed to provide complete details about idiopathic macular telangiectasia/idiopathic juxtafoveal telangiectasia/parafoveal telangiectasia including various groups, pathology, presentation, and management.

Oxaliplatin-induced papilledema: Rare case report.

Papilledema is the presence of bilateral optic disc edema in the presence of raised intracranial pressure and often is symmetric. We report a case of a 70-year-old male with rectal carcinoma on chemotherapy presented with minimal drop in visual acuity. The patient has bilateral disc edema and investigations including computed tomography and cerebrospinal fluid opening pressure were normal and no evidence of brain metastasis has been found. The patient was on oxaliplatin regimen and literature search has shown very few cases of platinum chemotherapy agents-induced papilledema. So far to our knowledge, oxaliplatin-induced papilledema has not been reported and knowing this condition can be sight saving for ill patients.

Peripheral primitive neuroectodermal tumor of the orbit in Graves' ophthalmopathy - A rare presentation.

Graves' ophthalmopathy is the most common cause of both unilateral and bilateral proptoses in adults. Peripheral primitive neuroectodermal tumor (pPNET) is a small round cell malignant lesion of neuroectodermal origin which very rarely affects the orbit. In this case report, we have discussed about a young woman with existing Graves' ophthalmopathy who presented with worsening proptosis; computed tomography imaging revealed an irregular mass lesion in the right orbit without bone erosion. Biopsy and immunohistochemistry of the mass lesion revealed features of primitive neuroectodermal tumor (PNET). The tumor was MIC-2 gene positive, and on follow-up, no recurrence was noted after successful surgical resection. PNET of the orbit is very rare, and to our best knowledge, this is the first case of peripheral PNET in patent with Graves' ophthalmopathy.

Preparation and uses of amniotic membrane for ocular surface reconstruction.

Background: The use of human amniotic membrane transplantation is rapidly increasing for the management of various ocular surface disorders. Despite its numerous advantages, amniotic membrane is not widely available due to the lack of awareness among ophthalmologists regarding its preparation and preservation techniques. Purpose: To provide an instructional video demonstrating the technique of harvesting, preparation, preservation of human amniotic membrane, and its uses in the management of ocular surface diseases. Synopsis: The amniotic membrane is the innermost layer of the human placenta. Properties of the amniotic membrane, like the presence of various growth factors, anti-inflammatory and anti-angiogenic factors, and its low immunogenicity, contribute to its ability to promote epithelial growth and differentiation with the reduction in fibrosis during healing. To harvest amniotic membrane, informed consent is obtained from a patient undergoing an elective caesarian section, and the donor is screened to exclude the risk of infections. Under sterile precautions, the amniotic membrane is separated from the chorion and washed free of blood clots. With the epithelial surface up, the amniotic membrane is spread uniformly without folds or tears on individually sterilized 0.22 µm nitrocellulose filter papers of the required sizes. The prepared filter paper with the adherent amniotic membrane is placed in freshly prepared Dulbecco's Modified Eagle's Medium and stored at -80°C. The amniotic membrane can be used for surgical procedures like symblepharon release, pterygium or dermoid excision, perforated ulcers, nonhealing epithelial defects, etc. Highlights: Instructional videos demonstrating the preparation and preservation of amniotic membrane are very sparse. This video clearly explains how any ophthalmologist can learn to prepare and preserve the human amniotic membrane and gives a glimpse of its properties, advantages, and scope of use.

Safety and efficacy of Aurolab aqueous drainage implant in refractory glaucoma: A prospective study.

Purpose: This study was conducted to assess the intraocular pressure (IOP) control and postoperative complications following a non-valved glaucoma drainage device (GDD) surgery in refractory glaucoma. Methods: This was a prospective interventional study conducted on patients with glaucoma refractory to maximal medications or failed surgical treatment who underwent Aurolab aqueous drainage implant (AADI; Aurolabs, India) surgery. Primary outcome measures were IOP control, postoperative complications, and reduction in the number of antiglaucoma medications (AGM). Results: Thirty-four eyes were analyzed and the mean follow-up was 16.06 ± 5.63 months. The preoperative median (Q1, Q3) IOP was 31 mmHg (28, 36.5) which decreased to 12 mmHg (12, 14) at 6 months postoperatively. The median (Q1, Q3) number of AGMs decreased from 3 (3, 4) to 0 (0, 1). Significant complications like implant extrusion and tube exposure were noted in two eyes. The total success and failure rates at 6 months were 91.1% and 8.8%, respectively. Conclusion: AADI is effective in achieving target IOP and significantly reduces the use of AGMs with good safety in the short term. Long-term follow-up studies are needed to assess long-term IOP control and cost-effectiveness.
