Incidence of Akreos AO60 intraocular lens opacification after concurrent or subsequent intraocular oil or gas use.

PURPOSE: To report the incidence of opacification in a consecutive series of 10 eyes that underwent scleral fixated Akreos AO60 placement with concurrent or subsequent contact with gas or silicone oil. METHODS: Consecutive case series. RESULTS: Three cases of IOL opacification were noted. Two cases of opacification occurred in patients that underwent subsequent retinal detachment repair with C3F8 and one with silicone oil. One patient underwent explanation of the lens due to visually significant opacification. CONCLUSION: Scleral fixation of the Akreos AO60 IOL is associated with risk of IOL opacification when exposed to intraocular tamponade. While surgeons should consider the risk of opacification in patients at high risk of requiring intraocular tamponade, only 1 in 10 patients developed IOL opacification significant enough to require explantation.

Incidence of Delayed Vitreous Hemorrhage in Patients With Retinal Tears Associated With Bridging Vessels.

BACKGROUND AND OBJECTIVE: The purpose of this article is to determine if outcomes in patients presenting with retinal tears with bridging vessels (BVs) differ from those without BVs. PATIENTS AND METHODS: A case control study of all patients presenting with retinal tears during a 3-year period was completed. Comparisons were made between patients with and without BVs. Variables included vitreous hemorrhage (VH) at presentation, delayed VH, initial and final visual acuity, need for surgery, and retinal detachment. RESULTS: There was a significant increase in the number of patients with a VH at presentation (75% vs 28%; P < .0001), delayed VH (31% vs 7.5%; P = .001), and incidence of pars plana vitrectomy (16% vs 1.3%; P = .002) in the BV cohort. There was no significant difference in time to VH (9.4 vs 38.8 days; P = .32) or final visual acuity (20/25 vs 20/25; P = .45) between the two groups. CONCLUSIONS: The presence of a BV is an important prognostic indicator for risk of delayed VH. Documenting the presence of a BV allows for appropriate patient counseling.

360 DEGREE ENDOLASER VERSUS FOCAL ENDOLASER IN PRIMARY RHEGMATOGENOUS RETINAL DETACHMENT REPAIR.

PURPOSE: To determine the efficacy of the 360-degree endolaser (360EL) versus focal laser during primary vitrectomy (PPV) for rhegmatogenous retinal detachment (RRD) repair. METHODS: A single-site retrospective chart review was performed on 241 patients who underwent PPV for primary RRD. Patients were assigned to two groups, PPV with 360EL (n = 183) and PPV without 360EL (n = 59). Only cases where surgeons performed 360EL on all RRDs or surgeons who never perform 360EL on RRDs were included. RESULTS: The single surgery anatomical success rate in the 360EL group was 90.2% compared with 86.5% with focal laser ( P = 0.619). Epiretinal membrane formation in 360EL group at 1 year was 44.4% versus 37% with focal laser ( P = 0.429). Cystoid macular edema formation within 1 year of surgery was 25.8% in 360EL group versus 11.9% with focal laser ( P = 0.04). CONCLUSION: The use of 360EL in PPV for RRD repair does not improve single-surgery anatomical success in routine RRDs when compared with PPV with focal laser.

Multimodal Imaging in Dengue-Fever-Associated Maculopathy.

Dengue fever can cause ocular complications that may not be easily identified during a regular eye examination. A high degree of suspicion and multimodal imaging will help characterize the lesions during acute stages of the infection.

A microbubble of gas as an early indication of macular hole formation after vitrectomy surgery for retinal detachment repair.

We present a novel case of a 67-year-old man who developed a full-thickness macular hole in the presence of a microbubble after repair of rhegmatogenous retinal detachment.

Pars Plana Vitrectomy Combined With Either Secondary Scleral-Fixated or Anterior Chamber Intraocular Lens Implantation.

PURPOSE: To compare visual outcomes among eyes that underwent pars plana vitrectomy (PPV) in combination with either anterior chamber intraocular lens implantation (ACIOL) or scleral suturing of posterior chamber lens (PCIOL). DESIGN: Retrospective comparative case series. METHODS: All eyes presented with aphakia or luxated or subluxated posterior chamber intraocular lens (IOL) following complicated cataract surgery, trauma, or spontaneous dislocation. Eyes involving visually significant macular pathology, past retinal detachment, follow-up of less than 6 months, and surgeries requiring the removal of an ACIOL were excluded. The main outcomes measured were final best-corrected visual acuity (BCVA) and surgical complication rates. RESULTS: Fifty-seven eyes met inclusion criteria; median follow-up was 13.2 months. Initial median BCVA for ACIOL patients was logMAR 1.301 (Snellen equivalent 20/400, range 20/20 to light perception); final median BCVA was logMAR 0.477 (Snellen equivalent 20/60, range 20/20 to light perception, P < .001). Initial median BCVA for PCIOL patients was logMAR 1.239 (Snellen equivalent 20/347, range 20/60 to light perception); final median BCVA was logMAR 0.301 (Snellen equivalent 20/40, range 20/20 to hand motions, P < .001). The change in BCVA between the 2 groups over the course of the study was similar (P > .05). More epiretinal membrane (ERM) formations occurred postoperatively in the ACIOL group (P = .011). Other complication rates were similar between both groups. CONCLUSIONS: PPV with secondary IOL placement is safe and effective, resulting in improved visual outcomes regardless of the technique used. Patients undergoing ACIOL placement have a higher incidence of ERM formation.

Early Vitrectomy for Spontaneous, Fundus-Obscuring Vitreous Hemorrhage.

PURPOSE: To examine the visual outcomes of early intervention in the setting of fundus-obscuring vitreous hemorrhage (VH) presumed to be due to posterior vitreous detachment. DESIGN: Retrospective comparative case series. METHODS: All eyes that presented with a fundus-obscuring VH, defined as vision of 20/400 or worse and requiring a B-scan at presentation from 2003 to 2013, were evaluated. Eyes with any history of retinopathy, macular degeneration, recent trauma, presentation greater than 2 weeks after onset of symptoms, or follow-up of less than 2 months were excluded. The main outcome measure studied was final best-corrected visual acuity (BCVA) as dependent on the time to surgery. RESULTS: Ninety-two eyes met inclusion criteria with a mean follow-up of 490 days. Initial BCVA was logMAR 2.218 (Snellen equivalent 20/3000-20/4000, range 20/400-light perception); final BCVA was 0.318 (Snellen equivalent of 20/40-20/50, range 20/20-light perception, P < .001). Fifty-six patients (60.8%) had either a retinal tear or a retinal detachment. Patients who underwent surgery within 1 week had no significant improvement over all others; however, a significant improvement was found when comparing early vs delayed surgery groups (P < .05). There was a significantly increased risk of developing a macula-off retinal detachment in patients who did not undergo surgery within 1 week of presentation. CONCLUSIONS: Early surgical intervention results in similar visual outcomes compared to a conservative approach. However, early intervention significantly reduces the incidence of severe vision loss related to macula-involving retinal detachment. This study highlights the importance of close follow-up given the high risk of retinal detachment in fundus-obscuring vitreous hemorrhage.

Atypical presentation of acute-onset endophthalmitis after uncomplicated pars plana vitrectomy.

A 70-year-old woman presented with signs of acute-onset endophthalmitis within 24 hours of surgery, with retinal hemorrhages and vascular changes in the absence of pain or significant inflammation. She had undergone uncomplicated 25-gauge pars plana vitrectomy for epiretinal membrane with presenting visual acuity of 20/40- and significant distortion. Vitreous culture revealed Staphylococcus epidermidis. Final visual acuity was no light perception with persistent pain, and the patient ultimately underwent enucleation. Although rarely, acute-onset postoperative endophthalmitis can present as retinal vasculitis with intraretinal hemorrhages and mild inflammation.

SURGICAL OUTCOMES IN PATIENTS WITH MACULAR PUCKER AND GOOD PREOPERATIVE VISUAL ACUITY AFTER VITRECTOMY WITH MEMBRANE PEELING.

PURPOSE: To evaluate whether patients with macular pucker (epiretinal membrane [ERM]) and good preoperative visual acuity (20/50 or better) benefit from small-gauge pars plana vitrectomy with membrane peeling. METHODS: Retrospective chart review of eyes undergoing small-gauge pars plana vitrectomy for ERM. Inclusion criterion was impaired visual acuity (20/50 or better) due to ERM. Exclusion criteria were preoperative visual acuity of 20/60 or worse, previous surgery (other than uncomplicated cataract surgery), and any documented evidence of macular or corneal disease that would limit visual potential. The main outcome measure was final visual acuity. Secondary outcomes included the role of internal limiting membrane peeling, and the effect of preoperative cystoid macular edema and internal limiting membrane peeling on visual acuity. RESULTS: One hundred and forty eyes met inclusion criteria of which 94% underwent 25-gauge vitrectomy (remainder had 23-gauge). There was a statistically significant improvement in final vision with the mean preoperative visual acuity of 0.305 logMAR (20/40) and 1-year visual acuity of 0.250 logMAR (20/35) (P = 0.0167). Cataract formation in phakic patients had a significant effect on the final visual outcome. Fifty-six of 63 patients (89%) in the phakic cohort developed a visually significant cataract by study end. The mean time to recommendation of cataract surgery was 8.4 months. Thirty-eight eyes (27%) had preoperative cystoid macular edema. Fifty-nine eyes (42%) underwent internal limiting membrane peeling. Neither one of these secondary outcome measures had a significant effect on the final visual outcome. CONCLUSION: Pars plana vitrectomy is both efficacious and safe an option for patients with ERMs and good preoperative vision. Eyes with an ERM and vision 20/50 or better had a statistically significant improvement in the final visual outcome after small-gauge pars plana vitrectomy surgery. As with large-gauge vitrectomy, cataract formation occurred in most phakic eyes within the first year after surgery.

Outcomes of eyes with lesions composed of >50% blood in the Comparison of Age-related Macular Degeneration Treatments Trials (CATT).

OBJECTIVE: To compare baseline characteristics, treatment frequency, visual acuity (VA), and morphologic outcomes of eyes with >50% of the lesion composed of blood (B50 group) versus all other eyes (Other group) enrolled in the Comparison of Age-Related Macular Degeneration Treatments Trials (CATT). DESIGN: Prospective cohort study within a multicenter randomized clinical trial. PARTICIPANTS: CATT patients with neovascular age-related macular degeneration (AMD). METHODS: Treatment for the study eye was assigned randomly to either ranibizumab or bevacizumab and to 3 different dosing regimens over a 2-year period. Reading center graders evaluated baseline and follow-up morphology in color fundus photographs, fluorescein angiography (FA), and optical coherence tomography (OCT). Masked examiners tested VA. MAIN OUTCOME MEASURES: Morphologic features and VA at 1 and 2 years. RESULTS: The B50 group consisted of 84 of 1185 (7.1%) patients enrolled in CATT. Baseline lesion characteristics differed between groups. In the B50 group, choroidal neovascularization size was smaller (0.73 vs 1.83 disc areas [DA]; P < 0.001), total lesion size was greater (4.55 vs 2.31 DA; P <0.001), total retinal thickness was greater (524 vs 455 µm; P = 0.02), and mean VA was worse (56.0 vs 60.9 letters; P = 0.002). Increases in mean VA were similar in the B50 and Other groups at 1 year (+9.3 vs +7.2 letters; P = 0.22) and at 2 years (9.0 vs 6.1 letters; P = 0.17). Eyes treated PRN received a similar number of injections in the 2 groups (12.2 vs 13.4; P = 0.27). Mean lesion size in the B50 group decreased by 1.2 DA at both 1 and 2 years (primarily owing to resolution of hemorrhage) and increased in the Other group by 0.33 DA at 1 year and 0.91 DA at 2 years (P < 0.001). Leakage on FA and fluid on OCT were similar between groups at 1 and 2 years. CONCLUSIONS: In CATT, the B50 group had a visual prognosis similar to the Other group. Lesion size decreased markedly through 2 years. Eyes like those enrolled in CATT with neovascular AMD lesions composed of >50% blood can be managed similarly to those with less or no blood.
