Vitreoretinal Lymphoma Masquerading as Central Serous Chorioretinopathy.

The following is a case of vitreoretinal lymphoma masquerading as central serous chorioretinopathy (CSCR). A 74-year-old man presented with blurred vision in the left eye with unilateral subretinal fluid in the setting of exogenous corticosteroid use, which was diagnosed as CSCR and resolved with corticosteroid cessation. He later experienced a similar self-limited episode in the right eye. Subsequently, he developed bilateral vitritis with yellow-white subretinal pigment epithelial infiltrates. Vitreous biopsy confirmed a diagnosis of large B-cell lymphoma. Vitreoretinal lymphoma can masquerade as a number of ocular pathologies, including CSCR.

Crystalline Retinopathy Following Intravitreal Clindamycin.

This case report describes a 74-year-old woman who developed a crystalline retinopathy following intravitreal injection of clindamycin. The patient presented with ocular toxoplasmosis in the left eye but was allergic to sulfa medications, so she was treated with intravitreal clindamycin. Subsequently, fine refractile yellow-white crystals were observed on examination of the left macula. Optical coherence tomography localized the crystals to the posterior hyaloid. Intravitreal clindamycin should be considered in the differential diagnosis of crystalline retinopathy. [Ophthalmic Surg Lasers Imaging Retina 2024;55:168-170.].

Stability of Vancomycin and Ceftazidime With Prolonged Storage at -20°C.

BACKGROUND AND OBJECTIVE: Vancomycin and ceftazidime are commonly used intravitreal antibiotics for suspected bacterial endophthalmitis. Many retina surgical practices prepare aliquoted individual doses in syringes that are then stored frozen for future use, but this practice has not been well studied. This investigation aims to examine the stability of frozen vancomycin and ceftazidime. MATERIALS AND METHODS: Samples of drugs were reconstituted monthly and placed in a -20°C freezer. At the end of 3 months and again at 6 months, a newly reconstituted drug constant was created and compared to a newly created reference sample. The frozen samples were compared to a freshly produced drug solution. Using high-performance liquid chromatography (HPLC), the peak heights were compared to evaluate stability. RESULTS: The vancomycin reference sample was 100 ± 1.67%. Values over time were 97.4 ± 0.75%, 98.8 ± 0.44%, 102.1 ± 0.4%, 100.5 ± 0.12%, 101.8 ± 0.12, 101.5 ± 0.11, and 100.6 ± 1.87 for 1, 2, 3(A), 3(B), 4, 5, and 6 months, respectively. The ceftazidime reference sample was 100 ± 1.8%. Values over time were 100.7 ± 1.78%, 100.0 ± 1%, 102.3 ± 1.55%, 117.5 ± 11.6%, 112.8 ± 1.64%, 123 ± 2.8%, and 117 ± 2.5% for 1, 2, 3(A), 3(B), 4, 5, and 6 months, respectively. CONCLUSION: Both vancomycin and ceftazidime were stable over 6 months under frozen conditions at -20°C. [Ophthalmic Surg Lasers Imaging Retina 2023;54:281-283.].

Efficacy of Perioperative Intravenous Dexamethasone on Postoperative Analgesia in Scleral Buckle Surgery: A Randomized Clinical Trial.

BACKGROUND AND OBJECTIVE: Postoperative pain is frequently reported following scleral buckle (SB) surgery. This study assessed the efficacy of perioperative dexamethasone on postoperative pain and opioid use following SB. MATERIALS AND METHODS: Forty-five patients with rhegmatogenous retinal detachments undergoing SB or SB and pars plana vitrectomy were randomly assigned to either standard care of postoperative oral acetaminophen and oxycodone/acetaminophen as needed or standard care plus 8 mg single-dose peri-operative intravenous dexamethasone. A questionnaire was administered on postoperative days 0, 1, and 7 to determine visual analog scale 0 to 10 pain score and number of opioid tablets consumed. RESULTS: Mean visual analog scale score and opioid use were significantly lower in the dexamethasone group on postoperative day 0 compared with control (2.76 ± 1.96 vs 5.64 ± 3.40, P = 0.002; 0.41 ± 0.92 vs 1.34 ± 1.43, P = 0.016). The dexamethasone group also demonstrated significantly lower total opioid use (0.97 ± 1.88 vs 3.69 ± 5.32, P = 0.047). No significant differences in pain score or opioid use were observed on days 1 or 7 (P = 0.078; P = 0.311; P = 0.326; P = 0.334). CONCLUSION: Single-dose intravenous dexamethasone following SB can significantly reduce postoperative pain and opioid use. [Ophthalmic Surg Lasers Imaging Retina 2023;54:238-242.].

Using a Capsular Tension Ring (CTR) Inserter for CTR Explantation in Cases of Posteriorly Dislocated Intraocular Lens-CTR-Capsule Complex.

PURPOSE: Explantation of a dislocated capsular tension ring (CTR) from the vitreous cavity can be challenging, typically requiring a bimanual hand-shake technique or cutting the CTR into segments. We present three cases of dislocated intraocular lens (IOL)-CTR-capsule complexes in which CTRs were explanted efficiently and safely by using a CTR inserter (CTR-I) through a clear corneal incision. METHODS: Retrospective case series. RESULTS: Capsular tension rings were successfully explanted by freeing the eyelet of the CTR from the capsule, engaging it with the CTR-I hook and retracting the CTR into the device's shaft while maintaining the entire IOL-CTR-capsule complex in a safe position behind the iris plane. No complications of the procedure were observed in all three cases. All patients had subsequent uneventful IOL exchange through sutureless scleral fixation during the same surgery. CONCLUSION: The CTR inserter provides a simple and efficient approach to CTR removal from IOL-CTR-capsule complexes dislocated into the vitreous cavity. Greater awareness of this technique among providers is needed.

Noninfectious Endophthalmitis Following Intraoperative Indocyanine Green.

BACKGROUND AND OBJECTIVE: The purpose of this article is to describe a cluster of four cases of severe postoperative inflammation in eyes that received intraoperative indocyanine green (ICG) from the same lot. PATIENTS AND METHODS: This was a retrospective chart review of patients from a single-center, retina-only group practice. The ICG lot associated with the inflammatory events was identified and analyzed with high-performance liquid chromatography with UV spectroscopy. RESULTS: Four patients presented on postoperative day 1 with severe inflammation. The first patient was treated with aqueous biopsy and injection of intravitreal antibiotics, followed by topical steroid and antibiotic drops. The subsequent three patients were treated with topical steroid and antibiotic drops. All patients had resolution of inflammation by postoperative day 14 (range 10 to 14 days). High-performance liquid chromatography with UV spectroscopy failed to identify a contaminant. CONCLUSIONS: The use of intravitreal ICG dye as a surgical adjuvant may uncommonly be associated with severe postoperative inflammation. This inflammation may resolve within weeks after topical corticosteroid and antibiotic treatment. [Ophthalmic Surg Lasers Imaging Retina. 2022;53:148-151.].

MACULAR HOLE CLOSURE WITH TOPICAL STEROIDS.

BACKGROUND AND OBJECTIVE: To report the outcomes of topical difluprednate 0.05% use in the closure of full-thickness macular holes. PATIENTS AND METHODS: Retrospective chart review of 4 patients with full-thickness macular holes who received difluprednate drops 4 times daily for a minimum of 12 weeks. Main outcome measures were macular hole status assessed with optical coherence tomography, visual acuity, intraocular pressure, and complications of treatment. RESULTS: All patients had macular hole closure within 12 weeks of difluprednate exposure. Mean time to macular hole closure was 5 weeks (range, 2-12 weeks). Visual acuity improved with macular hole closure. Average baseline visual acuity was 20/42. Average visual acuity after macular hole closure was 20/26 (P = 0.14). Two patients experienced increased intraocular pressure with topical steroid use. CONCLUSION: Exposure to difluprednate in this cohort of patients with full-thickness macular holes was associated with reduced macular edema, macular hole closure, and visual improvement.

Scleral Buckle Removal: Indications, Timing, Complications, and Long-Term Outcomes.

BACKGROUND AND OBJECTIVE: To report indications, timing, complications, and outcomes of scleral buckle (SB) removal surgery. PATIENTS AND METHODS: Retrospective observational case series. Eyes that underwent SB removal between 2010 and 2016 with greater than 1 year of follow-up were included. Main outcome measures were post-SB removal complications and best-corrected visual acuity (BCVA). RESULTS: Fifty eyes that underwent SB removal met the inclusion criteria. Indications include exposed SB (54%), infection (26%), diplopia (16%), and recurrent retinal detachment (4%). Mean and median intervals between SB placement and removal were 65 months and 30 months. Complications include recurrent retinal detachment (12%), transient ocular hypertension (6%), and persistent diplopia (4%). There was no significant change in mean BCVA after SB removal (P = .979). CONCLUSIONS: Exposed SB, infection, and diplopia are the most common indications for SB removal. The single-surgery success rate is high and the risk for complications is relatively low.

THE EFFECT OF ELECTIVE CATARACT EXTRACTION BY PHACOEMULSIFICATION IN EYES WITH VITREOMACULAR TRACTION SYNDROME.

PURPOSE: To evaluate the effect of cataract extraction (CE) by phacoemulsification on the vitreomacular interface (VMI) of eyes with preexisting vitreomacular traction (VMT). METHODS: Retrospective, observational case series. Patients with VMT who elected to proceed with CE, before any vitreoretinal intervention, were studied. Eyes with at least a 12-month follow-up period were included. The status of the vitreomacular adhesion at different time points was assessed using spectral-domain optical coherence tomography. The best-corrected visual acuity was recorded at different time points. Other macular and systemic comorbidities were documented. RESULTS: Fifteen eyes from 15 phakic patients with symptomatic VMT were included. Six of them were male subjects. Seven patients had diabetes mellitus and two of them also had nonproliferative diabetic retinopathy. The preoperative macular comorbidities included macular hole in six eyes (Stage 1 in 3 eyes and Stage 2 or 3 in another 3 eyes), epiretinal membrane in five eyes, and cystoid macular edema in four eyes. After uncomplicated CE, the VMT was released in 5 eyes, whereas in 10 eyes, CE did not significantly change the status of the vitreomacular adhesion. Three of 3 eyes with preexisting full-thickness macular hole (Stage 2 or 3 macular hole) were found to have Stage 4 macular hole shortly after CE. In seven of seven patients with diabetes mellitus, the status of the vitreomacular interface did not change after CE. Eventually, 7 of 15 patients underwent additional pars plana vitrectomy. Compared with the baseline vision, and vision before other interventions, the visual acuity after CE improved in 5 patients, remained unchanged in 7 patients, and decreased in the 3 patients with Stage 2 or 3 macular hole. The mean preoperative and early postoperative visual acuity was 20/59 and 20/68, respectively (P > 0.05). CONCLUSION: The effect of CE in phakic eyes with known VMT varies significantly. In the current case series, every eye with VMT and Stage 2 or 3 macular hole ended up with Stage 4 macular hole, although the VMT did not change significantly in the eyes of diabetic patients. Studies with larger sample size are needed to further elucidate the impact of elective CE on VMT.

Utility of a Genetic Screening Panel in Patients With Suspected Inherited Retinal Dystrophies.

BACKGROUND AND OBJECTIVE: To evaluate disease characteristics and frequencies of genetic mutations in a cohort of patients with known or suspected retinal dystrophies. PATIENTS AND METHODS: A cohort of 37 patients with known or suspected retinal dystrophies received genetic testing with a panel of 31 genes known to result in the development of retinal dystrophies. Disease characteristics identified during chart review were analyzed and related back to their associated genetic mutations in an attempt to link clinical features with genotypes. RESULTS: Eighteen of 37 patients (48.6%) tested positive for a variant(s) in one or more of the 31 genes tested. Mutations were discovered in 14 of the 31 genes, with USH2A being the most frequently mutated gene. Both gene-positive and gene-negative patient groups had similar disease characteristics including reduced visual acuity, legal blindness, dyschromatopsia, nyctalopia, and reduced peripheral vision. CONCLUSIONS: This investigation demonstrates the utility of genetic testing in a cohort of patients who carry a clinical diagnosis of retinal dystrophy. In this cohort, a significant number of patients had a genetic mutation or variant identified. [Ophthalmic Surg Lasers Imaging Retina. 2020;51:338-345.].

ONE-YEAR OUTCOMES OF A NOVEL SURGICAL APPROACH FOR FIXATION OF A POSTERIOR CHAMBER INTRAOCULAR LENS USING GORE-TEX SUTURE.

PURPOSE: To report the 1-year outcomes of a novel surgical technique for the fixation of a CZ70BD intraocular lens with Gore-Tex suture using cow-hitch knots. METHODS: A retrospective chart review of 15 patients (13 men and 2 women) who underwent fixation of a posterior chamber intraocular lens with Gore-Tex suture was performed. Short- and long-term outcomes data were collected 1 month and 1 year after surgery, respectively. RESULTS: Fourteen of the 15 patients met inclusion criteria and were included in the analysis. Mean visual acuity improved significantly from Snellen 20/491 preoperatively to Snellen 20/59 at postoperative month 12 (P = 0.002). The most common short-term complications included increased intraocular pressure (n = 6) and cystoid macular edema (n = 4). The most common long-term complications included increased intraocular pressure (n = 2) and iris capture of the intraocular lens (n = 2). CONCLUSIONS: One-year outcome data suggest that this technique is a reasonable surgical option for secondary intraocular lens placement in patients who lack capsular support.
