Ophthalmic presentation and outcomes of rhino-orbito-cerebral mucormycosis during the COVID-19 pandemic: An 18-month follow-up report.

PURPOSE: To investigate the long-term outcomes of COVID-19-associated rhino-orbito-cerebral mucormycosis (ROCM) patients. METHODS: Retrospective, observational study including all COVID-19 patients who developed ROCM and were referred to our oculoplastic clinic. RESULTS: Twenty-one patients with COVID-19-associated ROCM were included in this study. Twelve (57.1%) individuals were female with a mean age of 50.7±7.6 years (range 33-59), and nine (38.1%) were male with a mean age of 58.7±14.4 years (range 37-82). Corticosteroids were used in 85.7% of patients, and three patients received no systemic corticosteroids; 76.2% were diabetic and two of these developed new-onset diabetes mellitus (DM) after receiving corticosteroids during their treatment course. The average interval between COVID-19 and the development of ROCM in our subjects was 18.6 days (range 8-46 days). In our series of patients, decreasing vision, proptosis, and periorbital edema constituted the most prevalent presentation, seen in 52.4% of subjects. Endoscopic paranasal sinus debridement was performed a mean of 3.4 times in 95.2%, abscess drainage in one, and orbital exenteration in three (14.2%) patients. Orbital apex and bilateral paranasal sinus involvement were significantly associated with higher mortality, and the overall 18-month survival rate was 52.3%. CONCLUSION: Based upon common factors among the COVID-19-associated ROCM patients, we presume that DM and drug-induced immunosuppression are two main factors, which may lead to a higher rate of ROCM infection in areas where fungal spores are more likely to be present, such as hospitals.

Clinical outcomes of endoscopic dacryocystorhinostomy without preserving mucosal flaps in combination with silicone stent and steroid-soaked gelfoam.

PURPOSE: To report clinical outcomes of endoscopic dacryocystorhinostomy (En-DCR) combined with stenting and without preserving the nasal and lacrimal mucosal flaps. METHODS: In this prospective interventional case series, patients with primary acquired nasolacrimal duct obstruction who were candidates for En-DCR were enrolled. Patients with a known history of previous DCR, sinus surgery, rhinoplasty, nasal trauma, nasal anomaly, canalicular or punctal occlusion, or less than one year of follow-up were excluded. All patients underwent En-DCR and stenting followed by ostial packing using Gelfoam soaked with dexamethasone. The patients were assessed preoperatively, on the first postoperative day, after 2 weeks, 3 months, and 1 year. Postoperative outcomes were anatomical and functional success, defined as patent irrigation test and resolution of epiphora, respectively. The nasolacrimal drainage system was evaluated anatomically and functionally during the follow-up period. RESULTS: Eighty-three patients with a mean age of 54.36±15.27 years were enrolled. Of these, 61 patients (73.5%) were women. The mean duration of follow-up was 20.7±6.9 months. Anatomical success was achieved in all patients and remained stable during the study duration and at 1 year. Functional failure leading to epiphora was observed in 1 patient 3 months after surgery and resolved after re-DCR at year 1. Preoperative tenderness and purulent reflux were observed in 12%, 33.7% of which completely resolved postoperatively. Moderate and severe hemorrhage was observed in 12 (14.5%) and 2 (2.4%) patients, respectively. CONCLUSION: En-DCR without mucosal flap preservation in combination with silicone stent and steroid-soaked Gelfoam is a safe and highly successful procedure in patients with primary acquired nasolacrimal duct obstruction.

Comparison of Mersilene mesh and autogenous fascia lata in correction of congenital blepharoptosis: a randomized clinical trial.

PURPOSE: To asses the functional results and complications of Mersilene mesh as an alternative to autogenous fascia lata in the management of low function ptosis. METHODS: In a randomized clinical trial, 31 eyelids with poor levator function were operated on. In 16 eyelids Mersilene mesh (Group A) and in 15 eyelids autogenous fascia lata were used for frontalis suspension procedure (Group B). RESULTS: Nine patients with congenital unilateral and 11 patients with bilateral ptosis underwent sling procedure. There were no differences between the two groups with regards to functional (lid fissure height stability) and cosmetic (lid margin contour) results. Eyelid fissure increase was 4.00-/+1.46 mm in Group A and 3.13-/+1.72 mm in Group B. Change in eyelid fissure in both groups was significant (p=0.00, paired t-test), but intergroup difference was not significant (p=0.141, independent sample t-test). Follow-up for Group A was 14.2 (range 6-26) months and for Group B was 15.1 (range 9-29) months. Dermatochalasis was seen more in Group B (B/A = 10/2) and extrusion of Mersilene mesh was seen in two cases of Group A and none of Group B. Early complications such as corneal epithelial defects and entropion and late complications such as undercorrection were comparable in the two groups. CONCLUSIONS: Mersilene mesh with long-term functional results and low rate of complications is a suitable alternative to autogenous fascia lata as a suspensory material in ptosis surgery.

Complications of hydroxyapatite pegging: comparison between polycarbonate and titanium peg system.

PURPOSE: Polycarbonate peg has been customarily used for pegging of hydroxyapatite for years. For better movement, tissue tolerance, and to decrease the complications of pegging, titanium peg system has been used. This study compares the two systems. METHODS: Complications associated with pegging (polycarbonate: Bio-Eye or titanium: Dr-Perry new P-K) were retrospectively reviewed from the charts of 153 patients admitted to the Labbafinejad Medical Center, Tehran, Iran, for over 5 years from 1997 to 2003. RESULTS: A total of 153 cases were studied. Ninety-six (62.3%) were male and 57 (37.7%) were female, and the mean age was 27.7 years (6-59 years). In 88 cases pegs were poly-carbonate and sleeve system and in 65 cases pegs were titanium. Forty-one (46%) of cases with polycarbonate and 18 (27%) of cases with titanium had at least one or more complications (p=0.018). The most common complications were granulation tissue, discharge, overgrowth of conjunctiva, and peg falling out in 25%, 23%, 13%, and 8% in polycarbonate peg and 15%, 5%, 1.5%, and 0% in titanium peg group. The prevalence of the last three complications was statistically lower in titanium peg compared with polycarbonate. Twenty-five cases (35%) with polycarbonate peg and 5 cases (7.5%) with titanium peg had two or more complications (p=0.03). Peg removal was done in 11 cases of polycarbonate but only two cases of titanium peg in order to treat the complication. CONCLUSIONS: Both pegging systems had some complications, although these were less severe and prevalent in titanium peg. More studies on complications due to titanium pegs are recommended.

Dacryoadenitis as the earliest presenting manifestation of systemic Wegener's granulomatosis.

PURPOSE: To report a case presenting with dacryoadenitis as the earliest manifestation of systemic Wegener's granulomatosis (WG). DESIGN: Observational case report. METHODS: A 41-year-old woman initially presented symptoms of bilateral dacryoadenitis. She subsequently developed upper and lower respiratory tract involvement, scleritis and keratitis. RESULTS: Cytoplasmic antineutrophil antibody (c-ANCA) titer was positive. The lacrimal gland and lung biopsies were consistent with WG. The patient responded well to cyclophosphamide and prednisolone. CONCLUSIONS: Dacryoadenitis maybe the earliestpresenting manifestation of WG andprompt immunosuppressive chemotherapy may control it preventing the limited disease from progressing to a complete form and reducing its morbidity and mortality.
