AI Article Synopsis
- The study aimed to explore how the duration of macular detachment (DMD) affects visual acuity (VA) in patients with macula-off retinal detachment.
- The research included 202 patients who had successful reattachment surgery and were monitored for at least 3 months, focusing on the effects of DMD on their post-surgery vision.
- Findings reveal that VA significantly declines when DMD exceeds 6 days, suggesting that timely intervention within 7 days is crucial for better postoperative vision outcomes.
Article Abstract
Purpose: To determine the effect of duration of macular detachment (DMD) on visual acuity (VA) in patients with macula-off rhegmatogenous retinal detachment (RD).
Design: Retrospective observational case series.
Participants: Two hundred two consecutive patients (202 eyes) with primary uncomplicated macula-off RD, preoperative VA of 10/100 or worse, a precise history of when macular function was lost, successful reattachment surgery, and a minimal follow-up of 3 months.
Intervention: All RDs were repaired with a primary scleral buckling procedure performed by 3 vitreoretinal surgeons.
Main Outcome Measure: Visual acuity (best corrected and 3, 6, and 12 months postoperatively).
Results: Considering all eyes, the cumulative mean of the best-corrected postoperative VA (logarithm of the minimum angle of resolution [logMAR]) as a function of DMD shows a rapid worsening when DMD exceeds 6 days. Eyes were divided into 3 groups, corresponding to the DMD intervals immediate (within 10 days), delayed (11 days-6 weeks), and late (>6 weeks). Mean postoperative VAs (in logMAR) were 0.35+/-0.31 (between 20/40 and 20/50 Snellen equivalent) in eyes with DMD up to 10 days, 0.48+/-0.26 (20/60 Snellen equivalent) in the delayed group, and 0.86+/-0.30 (8/60 Snellen equivalent) in eyes with DMD longer than 6 weeks.
Conclusions: The cumulative mean of the best-corrected postoperative VA (logMAR) as a function of DMD shows a rapid worsening when DMD exceeds 6 days. Our results indicate that the scleral buckling procedure should be done preferably within a 7-day DMD.

Sub-Tenon's Block in Patients with Previous Encircling Band Surgery-A Feasibility Study.
J Clin Med
December 2024
Department of Anesthesiology and Pain Medicine, Bern University Hospital, Inselspital, 3010 Bern, Switzerland.
During the COVID-19 pandemic, reducing aerosol-generating procedures became fundamental, particularly in ophthalmic surgeries traditionally performed under general anesthesia (GA). Regional anesthesia, such as sub-Tenon's block (STB), is widely used in vitreoretinal surgeries, offering a safer alternative by avoiding airway manipulation. However, the altered orbital anatomy in patients with previous scleral explant surgery creates unique challenges to STB application.
View Article and Find Full Text PDFObjectives: This study aimed to evaluate the correlations between optical coherence tomography angiography (OCTA), best corrected visual acuity (BCVA), and macular integrity assessment (MAIA) microperimetry (MP) in both a control group and patients with rhegmatogenous retinal detachment (RRD). Additionally, it assessed differences between the groups and examined whether the time from symptom onset to surgery influenced microvascular or functional changes in the RRD group.
Methods: A cross-sectional study was conducted involving 47 patients who had undergone successful RRD surgery with pars plana vitrectomy (PPV) and sulfur-hexafluoride (SF6) gas injection, with or without scleral buckling (SB), and a control group of 136 healthy eyes.
"Central retinal artery occlusion following scleral buckling surgery with gas insertion in a patient with sickle cell disease".

Purpose: To describe a case of central retinal artery occlusion following scleral buckling procedure combined with pneumoretinopexy in a patient with sickle cell (HbSC) retinopathy (SCR).
Methods: Scleral buckling procedure, combined with injection of 0.3 ml of 100% perfluoropropane (C3F8) gas in the vitreous, was performed without intra-operative complications under general anaesthesia as treatment of two separate macula-sparing rhegmatogenous retinal detachments secondary to round holes, involving superior and inferior retina respectively, in the right eye of a 26-year-old Afro-Caribbean female with sickle cell disease.

Purpose: This study aims to examine the correlation between specific clinical parameters, such as axial eye length, and the onset of ocular hypertension "OH" following the use of silicone oil filling in patients with high myopia.
Method: In this retrospective analysis, we reviewed 214 eyes from 432 patients diagnosed with severe myopia, all of whom underwent vitrectomy and were treated with silicone oil filling. The study aimed to document the incidence and timing of postoperative ocular hypertension "OH" while assessing various factors, including demographic details, medical history, additional surgical interventions, and findings from supplementary examinations (such as axial length, silicone oil emulsification, and anterior chamber penetration).
