Long-Term Postoperative Structural and Functional Evaluation in Myopic Foveoretinal Detachment


Avoidable severe visual sequelae are common in severe myopic eyes. We analyzed the postoperative incidence of myopia traction macular disease (MTM) and the long-term postoperative structural and functional findings of myopia foveal retinal detachment (FRD) after macular surgery. Retrospectively at the surgeon for 35 severe myopic eyes in 31 patients who had foveal preservation technology to remove the internal limiting membrane by foveal FRD between October 2016 and April 2020, A series of continuous, relatively interventional, multicenter controlled cases was performed. Chromatic campimetry and multifocal electrocardiography were performed using microperimetry. The main results were surgical success and frequency of myopia FRD progression. The average evolution time for myopia FRD was 6.2 ± 3.5 months. The average follow-up period was 23.9 ± 12.1 months. The average time for FRD resolution for myopia was 5 ± 2.1 weeks. Using a pair sample permutation test, we found that surgery was associated with a significant improvement in visual acuity: BCVA (logMAR) decreased from 0.87 ± 0.15 before surgery to 0.48 ± 0.52 logMAR at P. = 0.00075. Did. 32 eyes (91.4%) showed elimination of myopia FRD. Three eyes (8.5%) showed progression: two (5.7%) developed full-thickness macular hole and one (2.8%) developed macular hole retinal detachment.  Postoperative test results of 4,444 showed abnormal retinal sensitivity in 102 and 302 visual field tests in 18 of the 19 eyes examined (94.7%). 16 of 17 eyes (94.1%) responded abnormally with microperimetry with a stable foveal center fixation pattern, and 20 of 21 eyes (95.2%) had a significant reduction in N1 and P1 wave amplitudes. Shown. The results showed a high incidence of microstructure regression (91.4%) and a low incidence of postoperative MTM structure progression (8.5%). Long-term structural and functional studies have revealed abnormal macula.

Independent and integrated ophthalmology – where justice and excellence meet

Image
About 2.2 billion people worldwide are visually impaired, at least half of whom are preventable. Current estimates of preventable causes of moderate to severe visual impairment or blindness include untreated refractive error (88.4 million), cataracts (94 million), glaucoma (7.7 million), corneal opacity (4.2 million), Includes diabetic glaucoma (3.9 million) and trachoma (3.9 million). 2 million), but mostly due to uncorrected presbyopia (826 million). Of gross domestic product.  The World Health Organization's resolution on "Integrated Human-Centered Ophthalmology (IPEC), Including Preventive Blindness and Visual Impairment". At the core of the resolution is to make IPEC the optimal model and ensure its widespread implementation. It is estimated that about two-thirds of the population of India may require free or subsidized eye care, and if they have no such access, they may suffer marginalization and exclusion. Affordable and accessible high-quality care delivered by t

A Revision of the International Classification of Retinopathy of Prematurity

Image
Retinopathy of prematurity (ROP) is still a major threat to premature babies' vision, with some cases resulting in irreversible vision loss. The International Categorization of Retinopathy of Prematurity (ICROP), a clinical classification system for acute ROP, was created in 1984 with input from experts from around the world.  Cryotherapy's efficacy in preventing retinal detachment and vision loss due to ROP was promptly proven in a multicenter clinical trial. 2 Since its inception, ICROP has enhanced clinical care by permitting reliable documenting of ROP, facilitating comparison of serial examinations by numerous doctors, and facilitating consultation with peers. The ICROP has undergone fine-tuning in the past, most recently in 2005. 3 The ICROP3 classification, which was released this year, was updated to better characterise the disease as it is being managed. 4 ICROP3's primary revisions address concepts added over the last two decades that are thought to influence the

Longitudinal Changes in Scotopic and Mesopic Macular Function as Assessed with Microperimetry in Patients with Stargardt Disease

Image
  The Nidek MP1S device was used to measure central 20 ° macular sensitivity under mesopic and scotopic conditions. Mean deviations (MD) from normal value for mesopic macular sensitivity for fovea (within 2 ° eccentricity) and extrafovea (4 ° 10 ° eccentricity) and the MD for scotopic sensitivity for extra fovea were calculated. Linear mixed effects models were used to estimate mesopic and scotopic changes and the mMD was 10.7 dB (p <0.001). Longitudinally, all eyes showed a statistically significant deterioration trend: the rates of foveal mMD and extrafoveal mMD and some were 0.72 (95% CI 0.37 to 1.07), 0.86 (95% CI: 0.58 to 1.14) and 1.12 (95% CI.). : 0.66 to 1.57) dB / year. In STGD1, the loss of scotopic macular function preceded the extrafovea and was faster than the loss of mesopic macular function. Scotopic and mesopic macular sensitivities using microperimetry provide alternative visual function results for STGD1 treatment studies. At baseline, all eyes had a larger sMD and
