BACKGROUND: Kidney and eye diseases may be closely linked. Tears of the retinal pigment epithelium (RPE) have been reported to be related to kidney diseases, such as IgA nephropathy and light-chain deposition disease. However, pigment epithelium tears associated with membranous nephropathy have not been reported or systematically analysed.
METHODS: A 68-year-old man presented with decreased right eye visual acuity. Optical coherence tomography (OCT) revealed cystic macular edema, localized serous detachment of the retina and loss of the outer retinal structure in the right eye and retinal pigment epithelium detachment (PED) combined with serous detachment of the retina in the left eye. Fundus fluorescein angiography (FFA) and indocyanine green angiography (ICGA) revealed giant RPE tears in the right eye and exudative age-related macular degeneration in the left eye. The patient also suffered from severe membranous nephropathy-autoimmune glomerulonephritis. Renal biopsy immunofluorescence revealed a roughly granular pattern, with immunoglobulin G (IgA), immunoglobulin G (IgG), IgM, complement C3(Components 3), λ light chain and κ light chain subepithelial staining.
CONCLUSIONS: It is hypothesized that severe membranous nephropathy caused immune complex deposition on the surface of Bruch membrane, resulting in weakened adhesion between the RPE and Bruch membrane and impaired RPE pump function, combined with age-related macular degeneration, leading to giant RPE tears in the right eye. Close attention should be given to the ocular condition of patients with membranous nephropathy to facilitate timely treatment and avoid serious consequences.

BACKGROUND: Knobloch syndrome (KNO, OMIM # 267,750) is a rare ciliopathy group sydrome characterized by a collagen synthesis disorder. It represents an uncommon cause of pediatric retinal detachment. This report presents two cases with different COL18A1 gene mutations, complicated by retinal detachment.
METHODS: Both cases exhibited high myopia and various degrees of occipital skull defect. The first case, a female, had bilateral congenital retinal detachment, posterior embryotoxon, and strabismus. The second case, a male, had unilateral congenital retinal detachment and neuromotor developmental delay. The first case, diagnosed in the early months of life, underwent successful retinal reattachment surgery. However, surgery was not performed on the second case, who presented with late-stage unilateral retinal detachment and pre-phthisis.
CONCLUSIONS: The report describes two patients with Knobloch syndrome, one of whom responded favorably to surgery for retinal detachment in both eyes. Successful anatomical results were achieved with early surgical interventions. It is essential to recognize the phenotypic and genetic heterogeneity within KNO.

OBJECTIVE: It is commonly accepted that phacoemulsification surgery is a risk factor for the development of posterior vitreous detachment (PVD) and may accelerate the process. This is an important consideration particularly in cases involving young patients who pre-operatively have no PVD, given the increased risk of retinal tears and detachments.
METHODS: A comprehensive literature search was conducted to identify studies reporting incidence of PVD post-uncomplicated phacoemulsification surgery. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement was used for search strategy. Of 3071 titles, 7 studies met the inclusion criteria; The outcomes measured were PVD occurrence by (1) time, (2) type, (3) age, (4) gender and (5) axial length, with all statistical analysis performed using Review Manager.
RESULTS: A total of 2034 eyes were included for analysis with a mean follow-up time of 28.3 months. 33.3% of patients developed a PVD, either partial or complete, with rates increasing in a time dependent manner. No significant difference was noted in sub-group analysis by age, gender or axial length.
CONCLUSIONS: The results from our systematic review show that uncomplicated phacoemulsification accelerates the physiological process of PVD development. Pre-operative evaluation of the vitreoretinal interface should be performed with careful post-operative follow-up advised in those without a pre-existing PVD.

Purpose: To examine the outcomes of chandelier endoillumination-assisted scleral buckling (chandelier scleral buckling) for rhegmatogenous retinal detachments (RRDs) and compare them with those of standard scleral buckling using indirect ophthalmoscopy. Methods: A literature search was performed on April 15, 2023. Outcomes analyzed included the primary anatomic success rates, surgical duration, and complication rates. A meta-analysis of proportions estimated the pooled success rate of chandelier scleral buckling. In addition, meta-analyses compared the success rates between pseudophakic eyes and phakic eyes having chandelier scleral buckling and compared success rates and surgical duration between standard scleral buckling and chandelier scleral buckling. Results: Thirty studies with 1133 eyes were included. The pooled primary anatomic success rate of chandelier scleral buckling was 91.7% (95% CI, 89.6%-93.6%). In studies comparing success rates between the 2 techniques, there was no significant difference (risk ratio, 1.01; 95% CI, 0.94-1.08; P = .80). The surgical times were significantly shorter with chandelier scleral buckling than with standard scleral buckling (mean difference, -18.83; 95% CI, -30.88 to -6.79; P = .002). There was no significant difference in the success rate between pseudophakic eyes and phakic eyes (risk ratio, 0.99; 95% CI, 0.91-1.08; P = .89). No cases of endophthalmitis were reported. Conclusions: Chandelier endoillumination-assisted scleral buckling may be a promising technique given its high rate of primary anatomic success for RRDs and success rates similar to those of standard scleral buckling. There was no significant difference in the efficacy of chandelier scleral buckling between pseudophakic eyes and phakic eyes.

OBJECTIVE: To assess efficacy and safety outcomes of subretinal fluid drainage methods during pars plana vitrectomy for rhegmatogenous retinal detachment.
METHODS: A systematic search strategy was conducted for studies published between January 2000 and October 2022. Included studies reported on either the safety or efficacy of two or more drainage methods during pars plana vitrectomy for patients with rhegmatogenous retinal detachment.
RESULTS: Two randomized and five observational studies consisting of 1,524 eyes were included. Best-corrected visual acuity at the last study observation and primary reattachment rates were similar across groups. A significantly lower risk of epiretinal membrane formation was associated with draining subretinal fluid through preexisting retinal breaks (risk ratio = 0.70, 95% confidence interval = [0.60, 0.83], P = <0.01, I 2 = 0%) or with perfluorocarbon liquid (risk ratios = 0.70, 95% confidence interval = [0.59, 0.83], P = <0.01, I 2 = 0%) compared with posterior retinotomy. The risk of an abnormal foveal contour was significantly greater in perfluorocarbon liquid-treated eyes relative to posterior retinotomy (risk ratios = 1.56, 95% confidence interval = [1.13, 2.17], P = <0.01, I 2 = 0%).
CONCLUSIONS: No significant differences were observed in the final best-corrected visual acuity at the last study observation and primary reattachment rates across different drainage methods. There remains limited information on the topic, so future research is warranted.

BACKGROUND: Toxoplasma gondii causes ocular toxoplasmosis (OT), involving inflammation, scarring, and retinal complications. The OT complications were retinal detachment (RD), and retinal breakage (RB). Surgical interventions like scleral buckling (SB) and vitrectomy are common. Limited understanding exists of the safety and efficacy of surgical management of RD/RB secondary to OT. Another complication is toxoplasmosis-related macular holes (tMH), with sparse evidence on surgical outcomes. This meta-analysis aims to clarify clinical characteristics, and surgical results, and enhance understanding of RD, RB, and MH secondary to OT.
METHODS: PubMed, Cochrane, Embase and Web of Science database were queried for retrospective studies, case series and case reports that provided information on RD, RB and MH associated with OT and reported the outcomes of: (1) Retinal reattachment of RD/RB and tMH closure; (2) Best-corrected visual acuity (BCVA) improvement; and (3) Complications. Heterogeneity was examined with I2 statistics. A random-effects model was used for outcomes with high heterogeneity. Statistical analysis was performed using the software R (version 4.2.3, R Foundation for Statistical Computing, Vienna, Austria).
RESULTS: Fourteen final studies, comprising a total of 96 patients were analyzed, 81 with RD or RB and 15 with tMH. Overall, surgical management was associated with several advantages: a high rate of retinal reattachment of RD/RB of 97% (95% Confidence Interval [CI] 92-100%; I2 = 0%), retinal reattachment of just RD of 96% (95% CI 89-100%; I2 = 30%) and tMH closure 97% (95% CI 87-100; I2 = 12%). There were significant differences in BCVA after surgeries in studies of RD/RB (MD 0.60; 95% CI 0.35-0.65; I2 = 20%) and MH (MD 0.67; 95% CI 0.50-0.84; I2 = 0%). The overall complication rate associated with surgical procedures in RD/RB secondary to OT was confirmed to be 25%.
CONCLUSIONS: The systematic review and meta-analysis showed that the treatment approaches currently in use are effective, with a remarkable rate of retinal reattachment of RD/RB, tMH closure, and substantial improvements in visual acuity. More randomized, long-term studies on disease and surgical factors can provide valuable insights into their impact on anatomical and visual outcomes.

To summarize the history and current trends in the use of scleral grafts in ophthalmology.
We conducted a review of the literature through the MEDLINE and Cochrane Library databases. The search terms were \"sclera\", \"graft\", and \"surgery\". The search resulted in 1596 articles, of which we evaluated 192 as relevant. The relevant articles were sorted chronologically and according to the method of using scleral grafts, which enabled the development of a review article.
The sclera has been routinely used in ophthalmology since the 1950s in many different indications. Some of these indications have become practically obsolete over time (for example, use in the surgical management of retinal detachment), but a large number still find application today (especially use in glaucoma or oculoplastic surgery, or as a patch for a defect in the sclera or cornea).
Even though allogeneic sclera is currently used less frequently in ophthalmology compared to other tissue banking products and the range of its indications has partially narrowed, it remains a useful material due to its availability and properties.

X-linked retinoschisis (XLRS) is an inherited retinal degeneration affecting males, characterized by splitting of the retinal layers. We herein present the outcomes of surgical treatment in a case of XLRS complicated by rhegmatogenous retinal detachment (RRD). A 22-year-old male presented to the emergency department due to decreased visual acuity and visual field defect in his left eye Oculus Sinister (OS) of 1 week duration. The patient reported an early onset retinal degeneration and decreased visual acuity in both eyes since childhood in his past ocular history. Upon presentation, best corrected visual acuity (BCVA) was 6/30 on the right eye Oculus Dexter (OD) and 6/120 OS. Fundus examination revealed areas of peripheral retinal schisis, and the characteristic spoke wheel pattern on the macula of both eyes. In OS, a temporal RRD involving the macula was identified. The patient underwent surgical treatment with pars plana vitrectomy with internal limiting membrane (ILM) peeling, endolaser, and silicone oil (SO) tamponade. BCVA in OS improved to 6/60 and schistic cavities resolution was observed in the immediate postoperative period. The patient\'s BCVA further improved to 6/19 at 1 month, as foveal anatomy showed relative improvement. However, there was a rapid reappearance of schisis spaces in the macular area at this point, which was also followed by progressive deterioration of foveal schisis by 3 months post-operatively. The resorption and recurrence of lamellar macular schisis changes after ILM peel and presence of SO, highlights that although XLRS findings can temporarily improve upon surgical intervention, the pathogenetic mechanisms contributing to disease phenotype remain to be elucidated.

Optic disc pits are hypothesized to form because of failure of embryonic fissure closure, which can also present with congenital defects in the choroid, RPE, and neurosensory retina. It is also associated with serous macular detachment. We present a case report of a 32-year-old man with an optic disc pit and independent choroidal coloboma below the inferior peripapillary area in the left eye, associated with macular retinoschisis with serous detachment.
