Creatively tiding over the crisis

Background: A patient with a retained intraocular metallic foreign body post?trauma was taken up for vitrectomy and intraocular foreign body removal. Unfortunately, the intraocular magnet was not available at the moment on the table! How a little bit of creativity and innovative thought helped us tide over this crisis is the content of this video. Purpose: To demonstrate magnetization of a metallic surgical instrument for temporary use in the event of unavailability of the intraocular magnet for intraocular foreign body removal. Synopsis: A ferromagnetic substance can be magnetized temporarily using an existing magnet. We obtained a general?purpose magnet and wrapped it in sterile plastic, using which we magnetized normal intraocular forceps and a Micro Vitreo Retinal (MVR) blade by giving about 20–30 strokes over the magnet in a single direction. This aligned the magnetic domains in the metal in a parallel fashion. These Do It Yourself (DIY)? magnetic instruments were then effectively utilized to remove the metallic intraocular foreign body. Highlights: The video showcases effectively harnessing the available resources and tiding over the dearth of a necessary instrument, with the right use of an innovative idea and some creativity!.

Acceptability of artificial intelligence-based retina screening in general population

Purpose: A deep learning system (DLS) using artificial intelligence (AI) is emerging as a very promising technology in the future of healthcare diagnostics. While the concept of telehealth is emerging in every field of medicine, AI assistance in diagnosis can become a great tool for successful screening in telemedicine and teleophthalmology. The aim of our study was to assess the acceptability of AI?based retina screening. Methods: This was a prospective non?randomized study performed in the outpatient department of a tertiary eye care hospital. Patients older than 18 years who came for a regular eye check?up or a routine retina screening were recruited in the study. Fundus images of the posterior pole were captured on fundus on a phone camera (REMIDIOTM, India) with a built?in AI software (Netra.AI) that can identify normal versus abnormal retina. The patients were then given an 8?point questionnaire to assess their acceptance and willingness toward AI?based screening. We recruited 104 participants. Results: We found that 90.4% were willing for an AI?based fundus screening; 96.2% were satisfied with AI?based screening. Patients with diabetes (P = 0.03) and the male population (P = 0.029) were more satisfied with the AI?based screening. The majority (i.e., 97.1%) felt that AI?based screening gave them a better understanding of their eye condition and 37.5% felt that AI?based retina screening prior to a doctor抯 visit can help in routine screening. Conclusion: Considering the current COVID?19 pandemic situation across the globe, this study highlights the importance of AI?based telescreening and positive patient approach toward this technology.

Coats’ disease – Prognostic factors for globe and vision salvage in children, a long-term experience

Coats’ disease is associated with poor outcomes, and there are limited studies on long?term outcomes of Coats’ disease. The purpose of our study is to identify various predictive factors to help in prognosticating the treatment outcomes in advanced Coats’ disease in children. Methods: This is a retrospective case series from a single tertiary eye care center of children (<18 years) diagnosed with coat’s disease. Sixty?seven patients with Coat’s disease were identified from the medical records from 2009 to 2020. Patients’ demographic data, clinical presentation, stage, extent of involvement, detailed treatment history, clinical sequelae post?treatment (including complications and anatomical and functional outcomes) were noted. Binary logistic regression was performed to correlate the predictive factors for anatomical and functional improvement. Results: Of the 67 patients, 51 eyes of 51 patients were included in the study. The male to female proportion was 2.2. Mean age at presentation was 4.98 ± 3.55 years (range: 2 months–15 years). Mean duration of follow?up was 31.53 ± 26.38 months. Overall, our globe salvage rate was 92.2%. We found that vitreoretinal fibrosis (P < 0.001), subretinal gliosis (P < 0.001), vitreous hemorrhage (P = 0.02), tractional or combined retinal detachment (P < 0.001), foveal scar (P < 0.006), and cataract (P < 0.001) to be important factors to affect the outcome. Conclusion: Advanced stage of presentation (stage 3B and above), diffuse involvement, cataract, vitreoretinal fibrosis (preretinal and subretinal), vitreous hemorrhage, tractional or combined retinal detachment, and anterior hyaloid proliferation are poor prognostic factors for globe salvage in advanced disease. Subretinal gliotic nodule or scar and lack of visual rehabilitation suggest poor functional outcomes

Unconventional techniques of fundus imaging: A review.

The methods of fundus examination include direct and indirect ophthalmoscopy and imaging with a fundus camera are an essential part of ophthalmic practice. The usage of unconventional equipment such as a hand‑held video camera, smartphone, and a nasal endoscope allows one to image the fundus with advantages and some disadvantages. The advantages of these instruments are the cost‑effectiveness, ultra portability and ability to obtain images in a remote setting and share the same electronically. These instruments, however, are unlikely to replace the fundus camera but then would always be an additional arsenal in an ophthalmologist’s armamentarium.

Fundus imaging with a mobile phone: A review of techniques.

Fundus imaging with a fundus camera is an essential part of ophthalmic practice. A mobile phone with its in‑built camera and flash can be used to obtain fundus images of reasonable quality. The mobile phone can be used as an indirect ophthalmoscope when coupled with a condensing lens. It can be used as a direct ophthalmoscope after minimal modification, wherein the fundus can be viewed without an intervening lens in young patients with dilated pupils. Employing the ubiquitous mobile phone to obtain fundus images has the potential for mass screening, enables ophthalmologists without a fundus camera to document and share findings, is a tool for telemedicine and is rather inexpensive.
