Purpose: Choroidal coloboma (CC) eyes are associated with a high risk of retinal detachment (RD), which are challenging to repair. Methods: We retrospectively evaluated medical records of 30 patients with CC associated with RD who underwent pars plana vitrectomy at our tertiary care center. Data recorded were age, CC and RD morphology, breaks, resurgeries performed, and final outcome. Results: Patients’ ages ranged from 2 to 49 years. CC was present in 53 of 60 eyes (88%), with 41 of 60 eyes (68.3%) associated with iris coloboma. RD was present in 36 of 53 CC eyes (67.9%), with 10 of 53 (18.9%) having bilateral RD. Thirty-one eyes with RD underwent 23-gauge pars plana vitrectomy. Colobomatous region breaks were detected in 5 of 31 eyes (16.1%), peripheral breaks only in 12 of 31 (38.7%), and both types in 3 of 31 eyes (9.7%). Silicone oil endotamponade was used in 29 of 31 eyes (93.5%) and perfluoropropane (C3F8) in 2 of 31 eyes (6.45%). Median postoperative follow-up duration was 31.5 months. Fourteen of 31 eyes (45.2%) developed redetachment requiring resurgery, with 50% developing within 6 months. Eighteen of 31 eyes (58.1%) maintained retinal attachment at last follow-up without endotamponade, whereas the rest were oil filled. Final visual outcome between macula-involved and macula-spared CC eyes was not significantly different; however, best visual acuity achieved any time during follow-up was significantly better in macula-spared eyes. Conclusions: RD surgery in CC eyes has a risk of frequent redetachments and subnormal gain of vision over the long term, especially in colobomas involving the macula. Endolaser in 360° peripheries in addition to barrage of the margin of the coloboma may be considered to help maintain the attached retina.

Pars Plana

Pars plana vitrectomy (PPV) with silicone oil implantation (SOI) was performed for advanced proliferative diabetic retinopathy (PDR) in 110 eyes of 98 diabetic patients. In, 77 eyes (70%) it was a primary SOI as part of the initial operation; in 33 eyes (30%) it was a secondary SOI in reoperations. Indications for SOI were traction retinal detachment of the posterior pole, combined traction and rhegmatogenous detachment, vitreous haemorrhage with florid vascularised fibrous proliferations, and recurrent vitreous haemorrhage after PPV. The patients were followed up for 24 to 72 months, with a mean of 53 months. At the end of follow-up, anatomical success was achieved in 63 eyes (57%), and functional success with visual acuity 0.01 and better in 35 eyes (32%). Functional failures were caused by retinal redetachment in 47 eyes (43%), by secondary glaucoma in 10 eyes (9%), retinal ischemia in 15 eyes (13%) and keratopathy in three eyes (3%). The functional success rate decreased with follow-up from 67% after six months to 50% by 60 months after SOI. Silicone oil bubble in the anterior chamber, rubeosis iridis, cataract, and glaucoma were the most frequent postoperative complications. PPV with SOI was highly effective in many serious complications of advanced PDR. Functional success was mostly lasting and markedly improved the quality of life of these patients.

Purpose: The purpose of this study was to compare rates of clinically significant complications between 23- and 25-gauge pars plana vitrectomy (PPV) in vitreoretinal surgery. Methods: Demographics, PPV indication, and surgical complications were reviewed. Patients with prior PPV or other retina surgery; cases requiring silicone oil removal, keratoplasty, or glaucoma valve implant; patients <18 years old; or patients with <4 months of follow-up were excluded. Comparative and descriptive statistics were used to evaluate the data. Results: A total of 579 eyes met inclusion criteria, and their charts were reviewed. Demographics, PPV indication, follow-up time, and lens status were similar ( P > .05). A 23-gauge PPV was performed more frequently than a 25-gauge PPV (328 vs 251 eyes, respectively). Although rates of eyes with a clinically significant postoperative complication requiring surgical intervention were higher in 23-gauge PPV (112/325, 34.4%) than in 25-gauge PPV (54/250, 21.6%), PPVs indicated by rhegmatogenous retinal detachment were more common with 23-gauge PPVs (155/325, 47.7%) than with 25-gauge PPVs (37/250, 14.8%; P <.001) and were more likely to have postoperative complications; however, rates of recurrent retinal detachments were not different in the 2 cohorts ( P = .862). When controlling for differences in indication, there was a moderately higher rate of postoperative complications following 23-gauge PPV ( P = .063). Conclusions: This retrospective review suggests that clinically significant complications are moderately more likely following 23-gauge PPV compared with 25-gauge PPV, even when the differences in surgical indication are considered.

The Right

A 36-year-old patient presented to the hospital with recurrent dislocation of the intraocular lens (IOL). The patient with the diagnosis of familial ectopia lentis was first operated on for crystalline lens subluxation in the left eye in 2007 and in the right eye in 2009. In both eyes, lens extraction with anterior vitrectomy and transscleral fixation of a rigid IOL was performed. In 2011, the IOL in the right eye luxated into the vitreous cavity due to ocular trauma. The patient underwent a pars plana vitrectomy with the IOL resuturation to the sclera. Seven years later, a spontaneous vision loss in the right eye was caused by a retinal detachment. The pars plana vitrectomy with silicone oil tamponade and a consequential oil removal three months later were performed in 2018. The follow-up examination revealed recurrent IOL dislocation in the same eye. Due to a history of previous suture-related complications a decision was made to remove the subluxated rigid polymethyl-methacrylate (PMMA) IOL and fixate to sclera a sutureless SOLEKO FIL SSF Carlevale lens. The purpose of this report is to present a single case of a 36-year-old patient who was presented to the hospital with recurrent dislocation of the intraocular lens. In a three-month follow-up period, a good anatomical and functional outcome was finally obtained with transscleral sutureless intraocular lens. This lens is an option worth considering especially in a young patient with a long life expectancy and physically active.

Abstract Context There are concerns about the long-term safety of conventional therapy on renal health in patients with hypoparathyroidism. Careful audit of these would help comparisons with upcoming parathyroid hormone therapy. Objective We investigated nephrocalcinosis, renal dysfunction, and calculi, their predictors and progression over long-term follow-up in patients with primary hypoparathyroidism (PH). Design and Setting An observational study at a tertiary care center was conducted. Participants and Methods A total of 165 PH patients receiving conventional therapy were evaluated by radiographs, ultrasonography, and computed tomography. Their glomerular filtration rate (GFR) was measured by Tc-99m-diethylenetriamine penta-acetic acid clearance. Clinical characteristics, serum total calcium, phosphorus, creatinine, hypercalciuria, and fractional excretion of phosphorus (FEPh) at presentation and during follow-up were analyzed as possible predictors of renal complications. Controls were 165 apparently healthy individuals. Results Nephrocalcinosis was present in 6.7% of PH patients but not in controls. Patients younger than 15 years at presentation and with higher serum calcium-phosphorus product were at higher risk. Nephrocalcinosis showed no significant association with cataract and intracranial calcification. Prevalence of renal calculi was comparable between hypoparathyroid patients and controls (5% vs 3.6%, P = .58). Fourteen percent of patients had a GFR less than 60 mL/min/1.73 m2. Increased FEPh during follow-up was the significant predictor of low GFR. Nephrocalcinosis developed in 9% of patients over 10 years of conventional therapy. Conclusion A total of 6.7% of PH patients had nephrocalcinosis, and 14% showed renal dysfunction. Prevalence of renal calculi was similar in patients and controls. Nine percent of patients developed nephrocalcinosis over 10 years of conventional therapy.

Background: Previous studies have shown that epiretinal membranes (ERMs) may be associated with abnormal outer retinal anatomy. However, long-term morphological and functional results of pars plana vitrectomy (PPV) with ERM and internal limiting membrane (ILM) peeling in eyes with central bouquet (CB) alterations have not yet been investigated. Methods: In a retrospective, consecutive study all patients underwent best corrected visual acuity (BCVA) testing and spectral domain optical coherence tomography (SD-OCT) before and after a mean of 20 months (range 3–70 months) postoperatively. CB abnormalities and ERMs were classified according to Govetto’s staging systems. Results: Of the 67 eyes, 22 (34%) showed CB abnormalities at baseline. The mean BCVA increased from 0.42 at baseline to 0.20 LogMAR at final follow-up (p < 0.001). Neither ERM stage (p = 0.06) nor CB stage (p = 0.939) at baseline were significant predictors of vision improvement following surgery. Conclusions: Our results show that baseline BCVA, but not classification of CB changes and ERM at baseline, seems to be a useful predictor for functional outcomes following PPV with ERM and ILM peeling in the long-term.

Purpose. We aimed at reminding that X-linked retinoschisis may also be seen in female patients and share our vitreoretinal surgical experience. Methods. The patient underwent pars plana vitrectomy including the closure of the macular holes with inverted ILM flap technique bilaterally. Lens extractions were performed by phacoemulsification during the removal of silicone oil endotamponade. Patient. An 18-year-old girl with X-linked retinoschisis and large macular holes in both eyes presented to the clinic of ophthalmology. It was confirmed that the patient had RS1 mutation Results. Nine-month-follow-up was uneventful for retinal findings. Significant improvement in visual acuity was achieved, and macular holes were remained closed. Conclusion. In cases with large macular holes due to XLR, an inverted ILM flap technique might be safe and effective. Four-month-silicone-endotamponade might be sufficient.

Purpose: Clinical presentation, treatment choices, and outcomes in cases of bleb-related endophthalmitis (BRE) at a tertiary care center over a 9-year period are described. Methods: A retrospective review was conducted of patients diagnosed with BRE at Duke Eye Center (Durham, North Carolina) from January 1, 2009 to January 1, 2018, with at least 6 months of follow-up, assessing demographic data, initial management, and visual acuity (VA). Results: Twenty eyes of 20 patients with BRE were identified. Median time from surgery to presentation was 6.53 years. Presenting VA of light perception only was significantly associated with the decision to pursue pars plana vitrectomy (PPV) as initial treatment (odds ratio 59.4, 95% CI, 2.1-1670.8, P = .016). Twelve eyes (60%) had culture-proven infectious endophthalmitis. Eleven eyes (55%) underwent PPV during treatment; 5 eyes underwent PPV on presentation, and 6 eyes underwent PPV after initial presentation. Compared with pre-endophthalmitis VA, 6 eyes that underwent subsequent PPV had greater VA loss at 6 months than cases not undergoing subsequent PPV (Early Treatment Diabetic Retinopathy Study line loss of 14 vs 4 lines, respectively; P = .044). Conclusions: BRE eyes presenting with light-perception VA were more likely to undergo initial PPV; yet many eyes in this study required PPV during treatment. Visual outcomes are often poor in BRE despite intensive management. There was greater VA loss from pre-endophthalmitis VA levels at 6 months in eyes undergoing PPV after initial treatment. Prospective studies are needed to assess the optimal role of PPV in patients with BRE.
