Distance and near vision changes after intravitreal anti-vascular endothelial growth factor injection in eyes with center-involving diabetic macular edema

Purpose: To elucidate distance and near vision changes after intravitreal injections in center?involving diabetic macular edema (CIDME) in phakic and pseudophakic groups. Methods: A retrospective study was done on 148 eyes (72 phakic and 76 pseudophakic) with center?involving DME. All eyes were treated with intravitreal anti?vascular endothelial growth factor (VEGF) injection. All patients underwent distance best?corrected visual acuity (BCVA) testing, near BCVA testing, dilated fundus examination, and optical coherence tomography (OCT) at baseline and follow?up visits. Eyes that could not improve after the first injection were given 2nd, 3rd, and more injections in the subsequent visits. Results: On follow?up, post injections in the phakic group (n = 72), there were 65 eyes (90.3%) with stable/improved near vision and 59 eyes (81.9%) with stable/improved distance vision, whereas in the pseudophakic group (n = 76), 63 eyes (82.9%) and 60 eyes (78.9%), respectively. Both in phakic and pseudophakic eyes, 7.7%–13% of the cohort showed only near vision improvement. Conclusion: In DME, besides the changes in distance vision, there are also changes in near vision. These changes should be taken into account while determining the response to anti?VEGF in DME treatment.

Scleral cut-down technique of subretinal fluid drainage in scleral buckle surgery for rhegmatogenous retinal detachment

Background: The art of scleral buckle (SB) surgery is being largely forgotten. However, it still remains a good option for selected cases of rhegmatogenous retinal detachment. Drainage of subretinal fluid (SRF) is one of the most crucial steps of the surgery. When performed correctly, it gives the advantage of immediate retinal reattachment, and it hastens recovery. However, it has its own set of complications. Purpose: To demonstrate, step by step, the scleral cut?down technique of SRF drainage in SB surgery for rhegmatogenous retinal detachment (RRD) and to discuss its indications, contraindications, and complications. Synopsis: Longstanding RRDs with bullous detachments, old age, inferior breaks, or multiple breaks are indications of SRF drainage. In shallow RDs or young patients, a non?drainage procedure may be preferred. It is safer to drain at the bed of the buckle. After the sclera is cut and dissected, it is essential to inspect the choroid for the presence of large vessels. Choroidal vessels are avoided from getting injured while perforating. The release of pigments indicates the end of the drainage. Various possible complications can be prevented by being careful in the surgical technique. Highlights: Diagrammatic illustrations explain the steps of the surgical technique. Intraoperative complications have been explained in an easy?to?understand manner with tips to manage such conditions and their prevention. The video highlights the correct way of performing SRF drainage

Surgical management of complicated retinal detachment in a case of retinal hemangioblastoma

Background: 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. 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. Purpose: To educate regarding the systemic workup, diagnosis, and surgical management of complicated retinal detachment in retinal hemangioblastoma. Synopsis: Systemic workup, diagnosis, and surgical steps in the management of complicated retinal detachment in retinal hemangioblastoma were performed. Highlights: 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.
