Purpose: To determine the characteristics of the macular dehiscence-associated epiretinal proliferations (EPs) in eyes with full-thickness macular holes (MHs).

Methods: The presence of EPs and the integrity of the retinal microstructures in eyes with MHs were determined by spectral domain optical coherence tomography in 390 eyes of 379 patients (29-89 years). The clinical findings, closure of the MH, the preoperative and postoperative best-corrected visual acuity, and the microstructural changes were compared between eyes with and without EPs.

Results: Epiretinal proliferations were detected in 31 of 390 eyes (7.9%). The preoperative best-corrected visual acuity and duration of reduced vision were not significantly different in the group with and without EPs (P = 0.09, P = 0.28). The axial lengths were significantly longer (P = 0.001), MH stage more advanced (P = 0.006), and the incidence of epiretinal membranes (P < 0.001) and intraretinal splitting (P < 0.001) were higher in eyes with EP. The EP was significantly correlated with the length of the ellipsoid zone defects (P < 0.001) and medium-reflective bridging tissue over the closed MH (P < 0.001). The closure rates and postoperative best-corrected visual acuities were not significantly different between the two groups (P > 0.99, P = 0.99).

Conclusion: The presence of EP was correlated with retinal microstructural changes and may support postoperative visual improvements with medium-reflective bridging tissue over the closed MH.

Coats-Like reaction post-vitreoretinal surgery for PDR managed with laser photocoagulation and adjunctive intravitreal steroids- a case report.

BMC Ophthalmol

January 2025

Dept. of Retina and Vitreous, Narayana Nethralaya, #121/C, 1st R Block, Chord Road, Rajaji Nagar, Bengaluru, 560010, India.

Purpose: To report a rare case of a Coats-like response developing after vitreoretinal surgery for proliferative diabetic retinopathy (PDR) and its successful management with retinal laser photocoagulation and adjunctive intravitreal steroids.

Case Description: A 52-year-old woman with a five-year history of type 2 diabetes mellitus and hypertension presented with decreased vision in the left eye (counting fingers at 1 m). Examination revealed high-risk PDR in both eyes, with a subtotal macula-off combined retinal detachment in the left eye.

Purpose: To develop a simple tool to remove retained submacular perfluorocarbon liquid bubbles (R-PFCL) and to inject recombinant tissue plasminogen activator safely in subretinal space in submacular hematomas.

Method: A retrospective, interventional study was performed where a simple homemade micro-viscous fluid control was developed to gain access to subretinal space in a controlled way. The rubber cap of the plunger of a 1-mL syringe was cut; this cut rubber cap of the plunger was fitted inside an empty 1-mL tuberculin syringe, and its end was fitted with the tubings of viscous fluid control of the vitrectomy machine.

Purpose: To analyze the clinical outcome of organ-cultured endothelium-outward preloaded DMEK (pDMEK) using the RAPID cartridge.

Methods: This prospective study included 80 eyes of 80 patients who received a pDMEK. Best-corrected visual acuity (BCVA), endothelial cell count (ECC), and central corneal thickness were measured preoperatively and 4 to 6 weeks, 3 months, 6 months, and 1 year postoperatively.

Purpose: To evaluate outcome and incidence of ocular hypertension after Descemet membrane endothelial keratoplasty (DMEK) and DMEK combined with cataract surgery (triple DMEK) after Nd:YAG laser iridotomy (IO) and surgical iridectomy (IE).

Methods: This is a single-center, retrospective cohort study of patients who underwent DMEK or triple DMEK surgery at the Department of Ophthalmology, University Hospital Düsseldorf, Germany, from January 2018 to June 2020 and had received either a prophylactic preoperative IO or an intraoperative IE. Patient demographic data; best corrected visual acuity; central corneal thickness; intraocular pressure (IOP); endothelial cell density; and complications such as occurrence of early postoperative IOP elevation, macular edema, rebubbling rate, and incidence of glaucoma were analyzed.
