Pediatric bacterial keratitis: clinical features, causative organisms, and outcome during a 13-year study period.

OBJECTIVE: To review the clinical features, causative organisms, complications, and outcomes of patients with pediatric bacterial keratitis at a tertiary care eye hospital. METHODS: We conducted a retrospective study at a tertiary care eye centre on clinically diagnosed pediatric patients with bacterial keratitis between 2007 and 2019. Poor outcomes were labelled if any of the following were present: final best-corrected visual acuity worse than 20/200, a drop in best-corrected visual acuity by 1 line or more, perforated corneas, endophthalmitis, and graft failure. RESULTS: The study included 43 cases of bacterial keratitis. Female and male patients represented 60.5% and 39.5% of the sample, respectively, with a mean age of 9.3 ± 5.9 years. The rate of culture positivity was 60.5%. The most common causative organisms were coagulase-negative Staphylococcus (23.1%), Pseudomonas (23.1%), and Streptococcus pneumoniae (19.2%). Culture-positive bacterial keratitis was associated with infiltrates ≥2 mm (p = 0.039), as determined by the results of multivariate analysis. Gram-positive and gram-negative bacteria exhibited 100% sensitivity to the tested fluoroquinolones. Complications included visually significant scars (55.8%), cataracts (14.0%), perforations (9.3%), corneal neovascularization (7.0%), nonhealing epithelial defects (7.0%), and endophthalmitis (4.7%). Corneal perforation was associated with the development of endophthalmitis (p < 0.001). On multivariate analysis, the only factor associated with a poor outcome was poor presenting visual acuity (p = 0.020). CONCLUSION: Gram-positive bacteria were the most common cause of pediatric microbial keratitis. Positive cultures were associated with larger infiltrates. The only adverse prognostic factor was poor presenting vision.

Ultrasound cyclo plasty in advanced glaucoma: Intermediate-term success, predictors for failure and complications.

PURPOSE: To report the intermediate-term success rate of ultrasound cyclo plasty (UCP), predictors for failure and complications in advanced glaucoma. METHODS: This study included patients with advanced glaucoma who underwent UCP. The main outcome measures were intraocular pressure (IOP), the number of antiglaucoma medications, and the presence of complications. Success was defined as an IOP reduction ≥30% and IOP between 6 mmHg and 18 mmHg with no vision-threatening complications. Cox proportional hazard regression analysis was performed to identify possible predictors for failure. RESULTS: We included 65 eyes of 58 patients in the study. The mean IOP and number of antiglaucoma medications decreased significantly from 27.60 ± 5.5 mmHg and 3.40 ± 0.9 at baseline to 17.80 ± 8.0 mmHg (35.51% reduction) and 2.43 ± 1.3 at 12 months and 17.10 ± 8.2 mmHg (38.04% reduction) and 2.41 ± 1.5 at 24 months, respectively (p < 0.01 for both). The success rates were 66.2% (43/65) and 72.4% (21/29), while the failure rates were 33.8% (22/65) and 27.6% (8/29) at 12 and 24 months postoperatively, respectively. The cumulative probabilities of overall success were 67.7 ± 5.8% and 33.8 ± 5.9% at 12 and 24 months, respectively. High baseline IOP and history of old glaucoma surgery were associated with a higher risk for failure (Hazard ratio = 1.10 and 5.82, p = 0.03 and p < 0.01, respectively). The most common complications were anterior chamber reaction (18.5%) and cataract development/progression (15.4%). Two eyes (3.1%) developed phthisis bulbi. CONCLUSIONS: Although UCP is effective in lowering IOP in eyes with advanced glaucoma, the intermediate-term success rates were moderate.

Outcomes of Ultrasound Cyclo Plasty in Primary Angle Closure Glaucoma.

PRCIS: Ultrasound cyclo plasty (UCP) can be useful in decreasing the intraocular pressure (IOP) and burden of antiglaucoma medications in eyes with primary angle closure glaucoma (PACG). Nevertheless, baselines IOP was an important determinant for failure. PURPOSE: To evaluate the intermediate-term outcomes of UCP in PACG. METHODS: This retrospective cohort study included patients with PACG who underwent UCP. The main outcome measures were IOP, number of antiglaucoma medications, visual acuity, and presence of complications. The surgical outcomes of each eye were classified as a complete success, qualified success, or failure based on the main outcome measures. Cox regression analysis was performed to identify possible predictors for failure. RESULTS: Sixty-two eyes of 56 patients were included in the study. The mean follow-up period was 28.81 months (±18.2). The IOP and number of antiglaucoma medications decreased from a mean of 23.03 (±6.4) mmHg and 3.42 (±0.9) to 15.57 (±6.4) mmHg and 2.04 (±1.3), respectively, in the 12 th month and to 14.22 (±5.0) mmHg and 1.91 (±1.5) in the 24 th month ( P <0.01 for all). The cumulative probabilities of overall success were 72.6±5.7% and 54.8±6.3% at 12 and 24 months, respectively. A high baseline IOP was associated with a higher risk of failure (hazard ratio=1.10, P =0.03). The most common complications were cataract development or progression (30.6%), rebound or prolonged anterior chamber reaction (8.1%), hypotony with choroidal detachment (3.2%), and phthisis bulbi (3.2%). CONCLUSIONS: UCP offers reasonable 2-year IOP control and reduction of the antiglaucoma medication burden. However, counseling on possible postoperative complications is needed.

Two-Year Outcomes of Ultrasound Cyclo Plasty as a First Procedure in Glaucoma.

PURPOSE: To evaluate the 2-year outcomes of ultrasound cyclo plasty (UCP) as a first procedure in glaucoma. METHODS: This retrospective cohort study included patients with uncontrolled glaucoma who underwent UCP as an initial glaucoma procedure. The main outcome measures were intraocular pressure (IOP), the number of antiglaucoma medications, visual acuity, and the presence of vision-threatening complications. Surgical outcomes of each eye were classified as either complete success, qualified success, or failure based on the main outcome measures. Differences in IOP control and success rates were compared in eyes with primary open-angle glaucoma (POAG) and primary angle-closure glaucoma (PACG). RESULTS: We included 98 eyes of 88 patients in the study. The mean follow-up period was 27.25 ± 10.1 months. At 12 and 24 months, mean IOP decreased significantly from 23.16 ± 6.4 mmHg to 16.57 ± 6.0 mmHg and 16.18 ± 5.2 mmHg, respectively, and the number of antiglaucoma medications decreased from 3.27 ± 0.9 to 1.86 ± 1.4 and 1.70 ± 1.7, respectively (p < .01 for all). There were no changes in visual acuity throughout the follow-up compared with preoperative levels. The cumulative probabilities of success were 64.3% (±4.8) [78.9% (±9.4) complete success, and 72.9% (±6.4) qualified success], and 42.9% (±5.0) [52.6% (±11.5) complete success, and 56.3% (±7.2) qualified success] at 12 and 24 months, respectively. The most common complications were cataract development/progression, anterior chamber inflammation, and macular edema. There were no significant differences in IOP, number of antiglaucoma medications, or survival rates between POAG and PACG groups. CONCLUSIONS: UCP can be used as an initial glaucoma procedure for reducing IOP and the number of antiglaucoma medications and offers comparable outcomes in POAG and PACG.

Monkeypox-Associated Disciform Keratitis.

PURPOSE: The purpose of this study was to describe a case of monkeypox (MPX)-associated disciform keratitis. METHODS: This is a case report. RESULTS: A 36-year-old male patient presented to the infectious diseases clinic with a 1-week history of disseminated pustular skin lesions, a 4-day history of constitutional symptoms, and redness in the left eye. Testing of blood, 2 skin lesions, and a conjunctival swab confirmed the presence of MPX virus by polymerase chain reaction. On ophthalmologic examination on the 17th day of illness, there was a corneal epithelial ridge that stained with fluorescein with disciform corneal edema and underlying keratic precipitates. The patient was treated with oral tecovirimat 600 mg twice a day for 14 days and topical prednisolone acetate 1% 4 times daily, starting 2 days later. On completion of oral treatment, his corneal findings had resolved except for a small subepithelial scar at which time topical steroids were tapered. CONCLUSIONS: MPX may cause disciform keratitis and scarring that closely resembles other ocular viral infections. Clinical trials are urgently needed to define the optimal management of human MPX infections and reduce vision loss.

Bacterial Keratitis: Clinical Features, Causative Organisms, and Outcome During a 13-year Study Period.

PURPOSE: This study aimed to review clinical features, causative organisms, complications, and outcome of bacterial keratitis cases at a tertiary eye hospital. METHODS: A retrospective study was conducted on clinically diagnosed bacterial keratitis cases from 2007 to 2019. Poor outcome was flagged if any of the following was identified: final visual acuity (VA) worse than 20/200, decrease in VA (1 line or worse compared with presenting VA), corneal perforation, endophthalmitis, failed graft, or cases requiring enucleation or evisceration. RESULTS: The study included 263 cases of bacterial keratitis with 169 cases (64.3%) of culture-positive bacterial keratitis. Gram-positive bacteria were found to be the causative organism in 106 cases (62.8%). The most common types were coagulase-negative staphylococci (23.1%) and Pseudomonas (23.1%). Culture-positive bacterial keratitis was associated with the development of anterior chamber reaction (≥1+) on multivariate analysis [adjusted odds ratio (OR): 3.03, confidence interval (CI): 1.23-7.45, P = 0.016]. The complications that occurred in the current cohort included visually significant scar (64.7%), perforation (10.8%), cataract (8.8%), nonhealing epithelial defects (8.0%), corneal neovascularization (4.9%), endophthalmitis (4.6%), and hypotony (1.5%). On multivariate analysis, diabetes mellitus (adjusted OR: 3.51, CI: 1.59-7.76, P = 0.002), poor presenting best-corrected VA (adjusted OR: 3.95, CI 1.96-7.96, P < 0.001), and positive cultures (adjusted OR: 2.36, CI: 1.11-5.00, P = 0.025) were associated with poor outcome. CONCLUSIONS: Culture-negative keratitis had less severe infection and better outcomes when compared to culture-positive bacterial keratitis. Factors associated with poor outcome included diabetes, poor presenting VA, and positive cultures.

Post-traumatic Fungal Keratitis and Endophthalmitis Caused by Coniochaeta Hoffmannii with Late Recurrence following Therapeutic Full-thickness Penetrating Keratoplasty.

BACKGROUND: To report a rare case of fungal keratitis and endophthalmitis due to Coniochaeta hoffmannii. METHODS: Case report. RESULTS: A 71-year-old immunocompetent male sustained a corneal laceration, traumatic cataract, and retinal detachment due to penetrating injury from a nail pulled from a wooden deck. The patient's postoperative course was complicated by infectious keratitis. Fungal cultures, DNA sequencing and analysis of the internal transcribed spacer sequence confirmed Coniochaeta hoffmannii. Topical and oral voriconazole treatments were initiated; however, due to impending perforation, a therapeutic corneal transplant was required. One year later, the patient developed a new corneal infiltrate at the graft-host junction: Corneal scrapings were culture positive for Coniochaeta hoffmannii. This was treated with topical and intrastromal voriconazole along with oral itraconazole 200 mg once daily for 8 months. CONCLUSIONS: Coniochaeta hoffmannii may cause recalcitrant keratitis and endophthalmitis, which required longstanding antifungal treatment.

Leptospermum Medical Grade Manuka Honey Ointment in the Treatment of Persistent Corneal Epithelial Defect.

BACKGROUND: To study the efficacy of 100% Leptospermum medical grade Manuka honey ointment in persistent corneal epithelial defects (CEDs). METHODS: Case series. RESULTS: Case 1 was a 25-year-old female patient who presented to the cornea clinic with a persistent CED (3.5 mm), following acanthamoeba keratitis, that had failed to respond to heavy, frequent lubrication drops and ointment. Two weeks later, after starting Leptospermum honey ointment (4 times per day), the CED healed totally. Case 2 was a 48-year diabatic, single-eyed female patient who presented with a persistent CED (1.5 × 1.5 mm) that had failed to respond to heavy, frequent lubrication drops and ointment. The CED healed three weeks after starting Leptospermum honey ointment (4 times per day). CONCLUSIONS: Leptospermum honey ointment can be a potential treatment for persistent epithelial defect.

Clinical Findings Predicting Posttraumatic Endophthalmitis after Repair of Open Globe Injuries.

BACKGROUND: To evaluate risk factors for developing endophthalmitis after repair of open globe injuries. METHODS: Retrospective chart analysis of 1303 patients from May 1996 till December 2019. RESULTS: All patients received prophylactic intravenous broad-spectrum antibiotics for 5-7 days. Endophthalmitis was clinically suspected in 37 (2.8%) eyes and was culture proven in 14 of these eyes (1.1%). Univariate analysis identified poor initial visual acuity at presentation, rural setting of injury, contaminated wound and lens injury as significant predictors for the development of clinically suspected endophthalmitis. Intravitreal antibiotics at the time of primary repair in eyes with high-risk characteristics decreased risk of developing endophthalmitis (OR: 2.28;95% CI,1.07-4.86; p = .033). CONCLUSIONS: Poor initial visual acuity, rural setting of injury, contaminated wound, and lens injury increased risk of suspected posttraumatic endophthalmitis. Prophylactic intravitreal antibiotics at the time of primary repair in eyes with high-risk characteristics reduced the risk of posttraumatic endophthalmitis.

Outcomes and Predictors of Failure of Ultrasound Cyclo Plasty for Primary Open-Angle Glaucoma.

Aims: To evaluate the outcomes of ultrasound cyclo plasty (UCP) for primary open-angle glaucoma (POAG) and identify the predictors of failure. Methods: This retrospective cohort study included patients with POAG who underwent UCP at King Abdul Aziz University Hospital, Riyadh, Saudi Arabia, between 2016 and 2021. The main outcome measures were the intraocular pressure (IOP), the number of antiglaucoma medications, and the presence of vision-threatening complications. The surgical outcome of each eye was based on the main outcome measures. Cox proportional hazard regression analysis was performed to identify the possible predictors of UCP failure. Results: Sixty-six eyes of fifty-five patients were included herein. The mean follow-up period was 28.95 (±16.9) months. The mean IOP decreased significantly from 23.02 (±6.1) to 18.22 (±7.0) and 16.44 (±5.3) mm Hg on the 12th and 24th months, respectively; the mean number of antiglaucoma medications decreased significantly from 3.23 (±0.9) to 2.15 (±1.5) and 2.09 (±1.6), respectively. The cumulative probabilities of overall success were 71.2 ± 5.6% and 40.9 ± 6.1% on the 12th and 24th months, respectively. High baseline IOP and the number of antiglaucoma medications were associated with a higher risk of failure (hazard ratio = 1.10 and 3.01, p = 0.04 and p < 0.01, respectively). The most common complications were cataract development or progression (30.8%) and prolonged or rebound anterior chamber reaction (10.6%). Conclusions: UCP reasonably controls the IOP and reduces the antiglaucoma medication burden in eyes with POAG. Nevertheless, the success rate is modest, with a high baseline IOP and number of medications.

Trends in antibiotic resistance in ocular samples in a tertiary eye centre in Saudi Arabia in 2003-2019.

OBJECTIVE: The aim of this study was to analyze the antibiotic resistance in ocular samples over a 16-year period. METHODS: This was a retrospective cohort study conducted at King Khaled Eye Specialist Hospital, Riyadh, Saudi Arabia (2003-2019). The study included corneal and conjunctival swabs and aqueous and vitreous samples. RESULTS: Coagulase-negative staphylococci exhibited a significant trend of increasing resistance over time to erythromycin (p < 0.001), oxacillin (p < 0.001), fusidic acid (p < 0.001), and moxifloxacin (p = 0.003). Staphylococcus aureus also showed a significant increase in oxacillin (p = 0.001), ofloxacin (p = 0.003), and moxifloxacin (p = 0.001) resistance patterns. Streptococcus pneumoniae demonstrated a significant increase in resistance to erythromycin (p = 0.01) and ofloxacin, which jumped from 0.80% in 2003 to 80% in 2019 (p = 0.015). No statistically significant increase in antibiotic resistance trend was observed for Pseudomonas. CONCLUSIONS: An increasing antibiotic resistance pattern was demonstrated, particularly among gram-positive organisms. Such findings warrant revision of the common ocular antibiotic prescribing strategy and consideration of alternative antibiotics.

Ultrasound Cyclo Plasty in Glaucoma: 2-Year Outcomes.

PRCIS: UCP offers reasonable IOP control and reduction of the antiglaucoma medication burden. PURPOSE: The purpose of this study is to evaluate the 2-year outcomes of Ultrasound Cyclo Plasty (UCP) in uncontrolled glaucoma. MATERIALS AND METHODS: A retrospective cohort study included patients with uncontrolled primary or secondary glaucoma who underwent UCP at King Abdul Aziz University Hospital, Riyadh, Saudi Arabia, between 2016 and 2021. The main outcome measures were intraocular pressure (IOP), number of antiglaucoma medications, and presence of vision-threatening complications. The surgical outcome of each eye was classified as complete success, qualified success, or failure based on the main outcome measures. RESULTS: One hundred and eighty-two eyes of 158 patients were included in the study. The mean follow-up period was 29.71 months (±18.1). The IOP and the number of antiglaucoma medications decreased significantly from a mean of 23.46 mm Hg (±6.3) and 3.33 (±0.9) to 17.33 (±7.1) and 2.14 (±1.4), and 16.24 (±6.3) and 1.90 (±1.5) on the 12th and 24 months, respectively. The overall success rates were 78.0% (143/182) and 85.6% (95/111), and the failure rates were 21.4% (39/182) and 14.4% (16/111) on the 12th and 24th months, respectively. The most common complications were cataract development/progression and anterior chamber reaction. CONCLUSIONS: UCP offers reasonable IOP control and reduction of the antiglaucoma medication burden.

Alterations in ocular microcirculation and oxygen metabolism in patients with lipemia retinalis.

PURPOSE: The study aims to assess the alterations in retinal oxygen saturation and retinal and choroidal blood flow in lipemia retinalis. METHODS: This was a cross-sectional study on 10 eyes (5 patients) with history of lipemia retinalis. The study comprised 10 eyes with documented history of lipemia retinalis and 10 participants as healthy controls. Patients with a confirmed history of lipemia retinalis were grouped into two cohorts based on their most recent fundus examination: untreated lipemia retinalis (abnormal fundus) and resolved lipemia retinalis (normal fundus). Both retinal arteriolar and venular oxygen saturation were measured using the non-invasive spectrophotometric retinal oximeter (Oxymap T1). The mean blur rate (MBR) of the optic nerve and choroidal blood flow were analyzed using a laser speckle flowgraph (LSFG). RESULTS: Patients with untreated lipemia retinalis had a significantly higher retinal arteriolar and venular oxygen saturation than that of the other two groups (p < 0.001). Moreover, patients with untreated lipemia retinalis had significantly smaller retinal arteriolar and venular diameters (p < 0.001). On LSFG, there was a significant difference in the overall MBR (p = 0.007) and vessel MBR of the optic nerve between the groups (p = 0.011). The patients with history of lipemia retinalis (untreated and resolved) exhibited a high overall MBR and vessel MBR of the optic nerve than that of the control group. There was a significant elevation of the optic nerve (p = 0.002) and choroidal blowout score (p < 0.001), while the resistivity index of the optic nerve (p = 0.001) and choroids (p = 0.002) was significantly lower in patients with resolved and untreated lipemia retinalis. CONCLUSIONS: There was a significant alteration in retinal oximetry, in untreated lipemia retinalis, and in retinal blood flow, in both the resolved and untreated groups. The increase in retinal blood flow and oxygen saturation may elucidate the preservation of visual acuity and function despite the fundus changes observed in lipemia retinalis.

Ultrasound Cyclo Plasty After Failed Glaucoma Surgery: Outcomes and Complications.

INTRODUCTION: The purpose of this study is to report the outcomes and complications of ultrasound cyclo plasty (UCP) after failed glaucoma surgery. METHODS: A retrospective case series included patients with previously failed glaucoma surgery who underwent UCP at King Abdul Aziz University Hospital, Riyadh, Saudi Arabia, between 2016 and 2021. The main outcome measures were: intraocular pressure (IOP), number of antiglaucoma medications and presence of vision-threatening complications. The surgical outcome of each eye was based on the main outcome measures. RESULTS: Seventy eyes of 70 patients were included in the study. The mean follow-up period was 31.89 months (± 17.5). The IOP and the number of antiglaucoma medications decreased significantly from a mean of 23.91 mmHg (± 6.3) and 3.43 (± 0.8) to 17.88 mmHg (± 8.1) and 2.48 (± 1.3) and of 16.74 (± 7.9) and 2.11 (± 1.3) at the 12th and 24th months postoperatively, respectively (p < 0.01 for both). The success rates were 77.1% (54/70) and 48.6% (34/70), while the failure rates were 22.9% (16/70) and 2.9% (2/70) at the 12th and 24th months postoperatively, respectively. The cumulative probabilities of success were 70.0% (± 5.5%) and 47.1% (± 6.0%) at the 12th and 24th months postoperatively, respectively. The most common complications were anterior chamber reaction (24.3%), cataract development/progression (18.6%), hypotony/choroidal detachment (4.3%), phthisis bulbi (1.4%) and aqueous misdirection (1.4%). CONCLUSIONS: UCP is an effective treatment modality to control IOP and decrease the burden of antiglaucoma medications in eyes with previously failed glaucoma surgery. Monitoring and counseling of possible postoperative complications are needed.

Factors Affecting the Efficacy of Botulinum Toxin Injection in the Treatment of Infantile and Partially Accommodative Esotropia.

PURPOSE: We aimed to investigate the effect of botulinum toxin (BT) injection on the treatment of infantile and partially accommodative esotropia (PAET). METHODS: This retrospective cohort study included patients who received BT injections for infantile and PAET between January 2015 and December 2018. Treatment was considered successful if orthotropia, consecutive exotropia, or esotropia within 10 prism diopters (PD) was achieved. RESULTS: The overall success rate was 47.4%, with a mean follow-up period of 27.8 months in 403 children. BT treatment was considered successful in 37.1% of cases of infantile esotropia and 53.1% of cases of partially accommodative esotropia. The average deviation angle before starting treatment was 35.5 ± 13.9 PD. Side effects 1 week after BT injections included transient overcorrection (63.8%) and transient ptosis (41.7%). There were no significant differences in the success rates between the different doses of BT (P = 0.69). The angle of deviation at presentation was significantly associated with the success rate of BT injection (failed group, mean: 38.1 ± 15.3 PD vs. success group, mean: 32.6 ± 11.6 PD; P < 0.001). Other factors associated with higher success rates were overcorrection at 1 week and PAET, while multivariate logistic regression analysis showed that a smaller angle of deviation and overcorrection (1 week after injection) were associated with a higher success rate. CONCLUSION: A smaller angle of deviation and transient overcorrection were associated with a higher success rate, and no significant difference was observed in the success rates of different BT doses.

Granulomatous panuveitis associated with Hodgkin lymphoma: A case report with review of the literature.

BACKGROUND: Intraocular lymphoma (IOL) is an uncommon ophthalmic malignancy and poses a diagnostic challenge. Uveitis associated with systemic lymphoma (USL) has been predominantly attributed to non-Hodgkin lymphoma (NHL) and rarely reported with Hodgkin lymphoma (HL) in the literature. METHODS: Case report with review of the literature. RESULTS: A 25-year-old healthy male presented with bilateral granulomatous panuveitis including vasculitis and discrete chorioretinal yellowish-white lesions. Macular optical coherence tomography (OCT) of both eyes revealed a disruption of ellipsoid and interdigitation zones over the areas of subretinal lesions as well as a small sub-retinal pigment epithelium (RPE) deposit in one eye. Thorough uveitis workup revealed clavicular, axillary and cervical lymphadenopathy, and biopsy of lymph nodes confirmed the diagnosis of nodular lymphocyte-predominant (NLP) HL. Six months later and after receiving chemotherapy, all symptoms and most of clinical signs resolved. CONCLUSIONS: Clinical features of USL do not differ between HL and NHL. However, the age of presentation may be much younger in HL. Ocular manifestations can precede systemic HL diagnosis, as shown in our patient. Therefore, USL should be part of the differential diagnosis of panuveitis. Paraneoplastic inflammation is thought be the cause of uveitis associated with HL. The sub-RPE deposit and disruption of ellipsoid and interdigitation zones on OCT have not been documented before as a manifestation of uveitis secondary to HL. In addition, the NLP subtype of HL was reported in only 1 case with uveitis in the literature.

Varicella Zoster Viral Retinitis following Chimeric Antigenic Response T-cell Therapy for B-cell Lymphoma.

PURPOSE: To describe the first case of varicella zoster virus (VZV) retinitis following chimeric antigenic response (CAR) T-cell therapy. METHODS: Case review. RESULTS: A 53-year-old male was treated with CAR T-cell therapy for refractory diffuse large B-cell lymphoma. Nine months after CAR T-cell therapy, he developed VZV skin infection and retinitis. The retinitis responded to systemic acyclovir therapy and intravitreal ganciclovir. CONCLUSION: VZV retinitis can occur following CAR T-cell immunotherapy.

Dacryops and clinical diagnostic challenges.

OBJECTIVE: The study aims to describe the clinical and histopathologic features of different types of dacryops and their clinical diagnostic challenges. METHODS: This is a retrospective cohort study of all surgically excised cases of dacryops in 2 tertiary eye hospitals in Riyadh, Saudi Arabia. RESULTS: The study included 58 dacryops specimens from 55 patients with an average age of 41.2 years (range, 4-78 years). The most common location was the upper lid (60.3%), whereas the least expected location was the caruncle (6.9%). The most common site of dacryops occurrence was in the accessory lacrimal gland (55.2%), the main lacrimal gland (32.8%), and then ectopic dacryops (12%). All patients presented with lid swelling alone except for 3 patients who experienced secondary mechanical ptosis. On physical examination, conjunctival scarring existed in 4 patients (6.9%). Preoperative diagnosis of dacryops was accurate in 44.8% of the cases. Dacryops of the main lacrimal gland was accurately diagnosed clinically in all cases compared with other locations, which was statistically significant (p < 0.001). The causes of inaccurate clinical diagnoses were hidrocystoma (26.9%), inclusion cyst (11.5%), and dermoid cyst (7.7%), whereas the remaining cases were diagnosed as cysts without a specific subtype (53.9%). Recurrence of the lesion was observed in 2 cases (3.5%). No clinical or histopathologic factors were associated with a risk of recurrence. CONCLUSION: Dacryops can represent a diagnostic challenge to ophthalmologists. Familiarity with clinical presentations and findings is required to diagnose dacryops outside the main lacrimal gland.
