A 40-year-old male presented with a complaint of sudden onset diminution of vision in the left eye for 2 weeks. He was a follow-up case with retinal hemangioblastoma in both eyes. He underwent two sittings of fundus fluorescein angiography-guided trans-pupillary thermotherapy 2 years back. Since then, he was regularly followed up for 2 years with stable vision and stable retinal findings. Alectinib chemical structure At present, the best-corrected visual acuity (BCVA) in the right eye is 6/6, and in the left eye, it is counting fingers 2 meters. On fundus examination, he had one active hemangioblastoma in the right eye and total retinal detachment in the left eye with multiple active lesions. The right eye was treated with a single sitting of thermotherapy, and the left eye underwent pars plana vitrectomy and angioma excision, followed by silicone oil tamponade. The immediate and late post-operative periods were uneventful, with successful anatomical and functional outcomes. The left eye BCVA on late follow-up was 6/36, no further treatment was advised, and the patient was kept under follow-up and observed closely.
To educate regarding the systemic workup, diagnosis, and surgical management of complicated retinal detachment in retinal hemangioblastoma.
Systemic workup, diagnosis, and surgical steps in the management of complicated retinal detachment in retinal hemangioblastoma were performed.
Close follow-up, keen observation, and prompt treatment in the early stages of the disease are indispensable to prevent untoward sequelae of retinal hemangioblastoma. A thorough systemic workup is necessary to diagnose the systemic involvements early. Surgery, if indicated for the retinal hemangioblastoma or its associated sequelae, should be performed diligently and with careful handling of blood vessels and anomalous tissues.

Surgeons often notice unexplained dilation of the pupil following an uncomplicated intra-ocular surgery. No definite line of treatment has been proposed for managing Urrets-Zavalia syndrome (UZS). The authors have previously documented the results of surgical pupilloplasty and have outlined this modality of treatment for cases with UZS.
To highlight the aspect of development of UZS post-operatively in the eyes following an intra-ocular surgery.
The video highlights the aspect of prevalence of the persistently dilated pupil that is non-responsive to topical miotics. Apart from associated glare, these cases often have raised intra-ocular pressure because of appositional closure of the anterior chamber angle. Surgical pupilloplasty pulls the iris tissue centrally, eventually releasing the mechanical blockage and often breakage of the peripheral anterior synechias as demonstrated by intra-operative gonioscopy and anterior segment optical coherence tomography.
Performing a surgical pupilloplasty can resolve the UZS, and timely intervention can also prevent the development of secondary glaucoma because of fallback of the iris tissue on the structures of the anterior chamber angle.

Expulsive suprachoroidal hemorrhage is a rare but dreadful complication of any ophthalmic surgery. Hence an ophthalmologist should know about the various risk factors, methods for preventing such a situation, and be aware of the various options for timely management to tackle the situation.
To discuss the risk factors, intraoperative signs, and ways of managing expulsive choroidal hemorrhage.
We discuss two cases having multiple risk factors, where the patients underwent tectonic penetrating keratoplasty. In view of extensive involvement of ocular structures, the patients were clearly explained about the guarded visual prognosis and the risk of auto-evisceration. Following trephination of host cornea, rise in intraocular pressure was identified by the increasing size of the vitreous seen prolapsing through the wound and markedly visible pulsations, along with subconjunctival bleeding. Suprachoroidal hemorrhage was suspected and immediate tamponade was given. However, bleeding was not controlled, and eventually, expulsion of all the intraocular contents occurred.
A surgeon must be aware of the risk factors, be prompt to identify the signs, and must take immediate actions for the management of expulsive choroidal hemorrhage, a rare but dreadful complication of intraocular procedures.

Research and awareness on refractive solutions for presbyopia, commonly known as the "Curse of the 40's," is essential as a large population in the world suffer from vision impairments. Population-based surveys have shown that one billion people in the world are in presbyopic age.
Many structural and physiological changes occur in the eye with the onset of presbyopia, including the decrease in amplitude of accommodation. At present, various static and dynamic techniques have been attempted to give presbyopes good vision at near-, intermediate-, and far-viewing distances. The aim of the video is to familiarize the modern-day ophthalmologists to these modalities.
In this video, we tried to summarize the indications and contraindications of presbyopic laser. Preoperative investigations like dominance testing and micro monovision testing are described. The role of neuroadaptation and patient counselling is emphasized. Static techniques described in the video include spectacles, contact lenses, surgical options like corneal inlays and onlays, corneal laser ablation, conductive keratoplasty, corneal implant lenses, INTRACOR and IOLs. Dynamic presbyopia correction (accommodative) is always surgical. This is split into lenticular (accommodating IOLs, piggyback, lens refilling, lentotomy) and scleral treatment (laser-assisted presbyopia reversal and scleral expansion bands).
The types of corneal laser ablation, which is otherwise very confusing, is elaborated in a step-wise manner here. The difference in approach of PresbyLasik (Nidek), Presbyond (Zeiss) - Laser Blended Vision, PresbyMax (Schwind), INTRACOR (Technolas) are explained with examples. Each approach has its pros and cons. Our challenge as a surgeon is to identify the best combination for the patient. This video illustrates the treatment options which can help break the curse of presbyopia.

Clinical examination revealed extensive pigment dusting in the corneal endothelium and the trabecular meshwork with de-pigmentation bands in the iris periphery. The patient was managed empirically with topical anti-glaucoma medications for high intra-ocular pressure. The patient was prescribed systemic antibiotics including cephalosporins and amoxicillin for respiratory symptoms. A rare condition called bilateral acute de-pigmentation of iris (BADI) was suspected after ruling out common entities, for example, viral kerato-uveitis, pigment dispersion syndrome, and Fuchs iridocyclitis. Covid-19 infection and systemic antibiotics including cephalosporins have shown to cause BADI in the literature. The patient responded well with good outcome.This report shows a case of corneal transplant rejection after vaccination against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), short after receiving the BNT162b2 vaccine, in a patient who had undergone keratoplasty more than 20 years ago, with no previous episodes of rejection and no other factor that could lead to the findings on his examinations. After treatment with high doses of topic, oral, and sub-conjunctival corticoids, the patient had a favorable therapeutic response. The signs of corneal transplant rejection must be oriented to the patients and the causing factors actively searched by ophthalmologists so that treatment is rapidly initiated and sequels are avoided. This report raises the question if these events are correlated and whether the patient should receive the second dose of the vaccine against SARS-CoV-2 or not.We piloted an innovation in teaching by conducting live virtual bedside clinics and evaluated the effectiveness compared to conventional bedside clinics. The purpose is to report the methodology and survey results of this innovation in teaching. A virtual bedside clinic was set up utilizing multiple audio-visual aids at a tertiary eye care facility. The bedside clinic was conducted and streamed live to pre-registered participants across the globe using the Zoom platform. The online survey was conducted comparing its effectiveness with conventional bedside clinics. A total of five sessions were conducted. A total of 2058 participants registered (411/session), of which 938 (45.57%) attended (187/session). A total of 287 participants (30.6%) responded to the survey. The respondents included ophthalmology residents (43.4%), fellows (19%), sub-specialty ophthalmologists (15.4%), general ophthalmologists (12%), and optometrists (9%). More than 95% of the respondents felt that these clinics were equally effective/better in imparting the following physical examination 97%, clinical knowledge 99.3%, clinical reasoning 98.3%, procedural skills 95%, and communication skills 96.5%. Respondents suggested that these clinics were better/equally effective in the following techniques general examination (96%), ocular motility (93.3%), nystagmus evaluation (93.3%), and anterior (80%) and posterior segment examination (73.3%). The hybrid mode presentation (97.3%) and discussion with the panel (100%) were reported to be equally effective/much better. Live virtual bedside clinics are a novel and effective way of continuing quality teaching and impactful learning. Most of the bedside manners, procedural skills, and examination techniques can be effectively taught through this virtual platform with a scope to improve anterior and posterior segment examination skills.The induction of posterior vitreous detachment (PVD) is an important step in the successful outcome of vitreoretinal surgery for various indications. This may pose a significant challenge intraoperatively in cases of strong adhesion between the posterior hyaloid and retina. Various techniques to achieve intraoperative PVD have been described which involve active aspiration as well as non-aspiration techniques to achieve a plane of separation between the posterior hyaloid and retina. Very frequently, combinations of these techniques might be necessary to achieve successful PVD induction. We describe a novel instrument that combines aspiration as well as non-aspiration techniques for PVD induction, Bapaye aspiration scraper. It is also useful in various vitreoretinal interface procedures due to its design and is compatible with small-gauge vitrectomy systems which are commonly used in modern vitreoretinal surgery.
