RESUMO

PURPOSE: To compare postoperative cosmesis, mydriasis, fundus visibility, and anterior chamber depth (ACD) in congenital and traumatic iris defects after single-pass four-throw pupilloplasty (SFTP). SETTINGS AND DESIGN: Hospital-based non-randomized interventional study. METHODS: SFTP was done along with phacoemulsification in six patients each with congenital and traumatic iris defects, and the patients were followed for a minimum period of 3 months. The postoperative pupil shape, size, mydriasis, and ACD were compared between the two groups. RESULTS: Tissue approximation was successful in 11 out of 12 patients (91.7%), whereas it failed to do so in one patient with traumatic iris tear (8.3%). A central round pupil was attained in all six patients with congenital defects (group 1), whereas in the traumatic group (group 2), a central round pupil was attained in four cases. Group 1 did not show a significant reduction in horizontal pupil diameter, but group 2 had a significant reduction in pupil diameter postoperatively. Mydriasis and fundus visibility were satisfactory in all cases. There was a significant deepening of ACD in both groups. CONCLUSION: Traumatic mydriasis usually requires SFTP at two opposite poles to achieve a central pupil with a significant reduction in pupil size, whereas congenital coloboma requires SFTP to be done at the site of coloboma with occasional enlargement at the opposite pole if the pupil is eccentric.

RESUMO

PURPOSE: To evaluate the safety and efficacy of sutureless intrascleral intraocular lens (IOL) fixation combined with modified iris cerclage pupilloplasty for treating aphakia and traumatic mydriasis. METHODS: Five patients with aphakia and traumatic mydriasis were operated on by the same surgeon. All patients underwent sutureless intrascleral IOL fixation combined with modified iris cerclage pupilloplasty and were followed up for ≥6 months. Best-corrected visual acuity (BCVA) was measured using the logarithm of the minimum angle of resolution (logMAR). BCVA, intraocular pressure (IOP), pupil diameter, and corneal endothelial cell count (CECC) preoperatively and postoperatively were statistically analyzed. The pupil shape, photophobia, IOL position, and surgical complications were evaluated. RESULTS: The mean BCVA was significantly improved 6 months postoperatively (0.26 ± 0.17 logMAR, P = 0.042) than preoperatively (0.50 ± 0.30 logMAR). No significant difference was observed between the preoperative and postoperative IOP (P = 0.138). The mean pupil diameter significantly reduced postoperatively than preoperatively (3.44 ± 0.35 mm vs. 7.28 ± 0.35 mm, P = 0.043). There was no significant decrease in CECC postoperatively (P = 0.225). The pupil shape was round-like, and photophobia disappeared in all patients. No intraoperative or postoperative complications occurred. CONCLUSION: Sutureless intrascleral IOL fixation combined with modified iris cerclage pupilloplasty is a safe and efficient procedure for treating aphakia traumatic mydriasis patients without sufficient capsular support.

RESUMO

Herein we describe 2 cases of persistent mydriasis after gonioscopy-assisted transluminal trabeculotomy for open angle glaucoma. Both surgeries were uneventful, but the patients experienced postoperative hyphema and intraocular pressure elevation. They then developed persistent fixed and dilated pupils resistant to pilocarpine that led to intolerable photosensitivity and glare. An iris cerclage pupilloplasty was performed with adequate relief of symptoms in one case.

RESUMO

Congenital ectropion uveae (CEU) is a rare anomaly of the embryonic development of the anterior segment of the eye. We report the case of a 5-year-old child with an undiagnosed CEU who was treated urgently for an acute angle closure attack. CASE DESCRIPTION: A 5-year-old child was referred urgently for evaluation of anisocoria with mydriasis of the right eye and severe headache. Brain imaging with contrast injection was initially performed in the pediatric emergency department and ruled out central nervous system pathology. The initial examination of the right eye revealed an intraocular pressure (IOP) of 37mmHg, corneal edema, congenital ectropion uveae, mydriasis with pupillary block, a closed angle on gonioscopy, and a clear lens. The examination of the left eye was unremarkable, with no visible CEU. The initial management consisted of medical treatment with topical glaucoma drops and miotics and acetazolamide at 10mg/kg/d. Re-evaluation under general anesthesia showed persistent mydriasis and no resolution of the pupillary block. Filtering surgery was performed in the absence of a complete response to medical treatment, allowing control of IOP without drops and complete regression of the corneal edema. DISCUSSION: CEU is a rare malformation, and pressure complications represent an insignificant proportion of pediatric glaucoma cases. The acute presentation of acute angle closure in this potentially blinding short-term setting, however, makes detection and management difficult in very young children in a great deal of pain. Only one similar case has been reported in the pediatric literature. CONCLUSION: Acute angle closure complicating CEU is exceptional and difficult to diagnose in a pediatric context. Parents of children with this predisposing condition should be informed of the need to consult urgently when clinical signs of elevated intraocular pressure appear.

RESUMO

Multisystemic smooth muscle dysfunction syndrome (MSMDS, OMIM # 613834) is a rare autosomal dominant condition caused by pathogenetic variants of ACTA2 gene that result in impaired muscle contraction. MSMDS is characterized by an increased susceptibility to aneurismal dilatations and dissections, patent ductus arteriosus, early onset coronary artery disease, congenital mydriasis, chronic interstitial lung disease, hypoperistalsis, hydrops of gall bladder, and hypotonic bladder. Here, we report an early diagnosis of a MSMDS related to ACTA2 p.Arg179His (R179H) mutation in a newborn and performed a review of the literature. An early diagnosis of MSMDS is extremely important, because of the severe involvement of cardiovascular system in the MSMDS. Multidisciplinary care and surveillance and timely management of symptoms are important to reduce the risk of complications.

RESUMO

We report a case of unilateral acute-onset ptosis and mydriasis in a girl 2 years and 7 months of age from an area endemic for Lyme disease. She lacked other signs of oculomotor nerve palsy. She tested positive for Borrelia burgdorferi and negative for Bartonella henselae on serology and was diagnosed with Lyme neuroborreliosis. The ptosis and mydriasis resolved after 1 week of oral doxycycline.

RESUMO

BACKGROUND: Topical glycopyrronium tosylate (GT) is an anticholinergic medication for treatment of axillary hyperhidrosis. Pharmacologic mydriasis and anisocoria from topical GT has been reported and may be underrecognized. This study aims to clinically characterize patients presenting with pharmacologic mydriasis from exposure to this medication. METHODS: This study is a retrospective observational case series. A multicenter chart review of 16 patients diagnosed with pharmacologic mydriasis secondary to topical GT was performed. RESULTS: Eight patients (50.0%) were age 18 years and younger, and 14 patients (87.5%) were female. Unilateral mydriasis (anisocoria) occurred in 14 patients (87.5%). Fourteen patients (87.5%) did not initially volunteer topical GT as a "medication," and the history of topical GT exposure needed to be elicited with further questioning. Hand hygiene details were known for 12 patients, and all reported that they did not wash their hands after GT application. Six patients (37.5%) were soft contact lens users. One patient had possible exposure through a family member's use of the medication. Ocular symptoms were common (blurry vision [11 patients, 68.8%] and eye dryness [7 patients, 43.8%]), but systemic anticholinergic symptoms were uncommon (such as constipation [1 patient, 6.3%] and urinary symptoms [3 patients, 18.8%]). CONCLUSIONS: Mydriasis associated with topical GT seems to be a consequence of local exposure rather than systemic toxicity. Because patients may not volunteer topical GT as a medication, eliciting a history of exposure often requires further specific questioning. Soft contact lens wear and poor postapplication hand hygiene seem to be associated with mydriasis in GT use.

RESUMO

Missense mutations in the smooth muscle-specific isoform of the alpha-actin (ACTA2) gene, which encodes smooth muscle actin, congenitally cause systemic smooth muscle dysfunction, leading to multiple systemic smooth muscle dysfunction syndrome. This disease is often diagnosed through the development of congenital mydriasis, patent ductus arteriosus, or thoracic aortic aneurysm at a young age. Some patients develop cerebrovascular lesions, also known as ACTA2 cerebral arteriopathy, which cause ischemic stroke and require surgical revascularization. However, an effective and safe treatment has not yet been established owing to the rarity of the disease. Furthermore, most reports of this disease involve children, with only a few reports on adults and few detailed reports on treatment outcomes published to date. We report a 46-year-old woman with ACTA2 cerebral arteriopathy caused by Arg179His, the most common mutation in this disease; she is the oldest patient reported with this disease to the best of our knowledge. The patient was diagnosed with multiple systemic smooth muscle dysfunction syndrome and ACTA2 cerebral arteriopathy after experiencing a stroke in the right cingulate gyrus. She underwent direct triple bypass with three anastomoses of the right superficial temporal artery to the middle and anterior cerebral arteries. She developed an ischemic stroke as a postoperative complication.The efficacy and safety of this procedure have not been clearly confirmed owing to the frailty of the donor superficial temporal artery and the poor development of collateral circulation; however, direct bypass should be considered a treatment option for patients experiencing progressive multiple strokes.

RESUMO

A sensitive and accurate hydrophilic interaction liquid chromatography - tandem mass spectrometry method (HILIC-MS/MS) was developed and validated for the determination of phenylephrine concentration in Dried Blood Spot (DBS) samples from preterm infants, after ocular administration of an ophthalmic solution with phenylephrine. Sample preparation involved the extraction of the analyte from an 85 µL DBS sample with methanol - acetonitrile (50:50, v/v). Chromatographic separation was achieved on an ACQUITY UPLC BEH AMIDE column, under isocratic conditions within a 5 min run. Detection was achieved with a triple quadrupole MS applying electrospray ionization in positive mode. The method was fully validated and proved precise and accurate with in a linear range of 0.59-3.53 ng/ml in blood. The method was developed to provide insights on the level of exposure of infant population to phenylephrine after ocular administration.

RESUMO

Acute-onset anisocoria or mydriasis in children carries a broad differential diagnosis and includes both benign and life-threatening causes, ranging from systemic or topical drug use to peripheral or central nervous system disease. The topical anticholinergic agent glycopyrronium (approved by the Food and Drug Administration in June 2018) is used to treat hyperhidrosis. We present the first case series of pediatric patients presenting with acute mydriasis due to exposure to glycopyrronium wipes. Six cases (ages 12-16) were identified: 3 presented emergently and 3 to a primary care physician. Additional symptoms included blurry vision (4/6) and unilateral headache (1/6). In 3 cases, use of glycopyrronium wipes was not elicited initially, neuroimaging was obtained, and ophthalmology (2/3) or neurology (1/3) was consulted. One patient remained undiagnosed and presented emergently again 2 months later. In all patients, symptoms resolved without further treatment.

RESUMO

Case presentationA 10-month-old boy was admitted to the emergency department due to a sudden onset of left unilateral mydriasis (figure 1). His medical history was unremarkable. A minor head trauma 2 days before was reported, without alarming signs or symptoms. His mother was putting him to sleep, after coming back from work, when she noticed a different pupil size and promptly went to the ED with her husband. The parents denied any use of medications, including nebulised therapy or direct contact with plants. The child was well appearing and his vital signs were within the standard age limits. His extraocular motility was normal as well as the rest of his neurological and physical examination. Parents' behaviour was somehow remarkable. Even though the child was not suffering, the mother seemed very worried while the father was nervous and aggressive, repeatedly asking for a discharge.

RESUMO

La corrección quirúrgica de la afaquia se realiza mediante varias técnicas que permiten fijar los lentes intraoculares en la cámara posterior, suturados al sulcus ciliar o por fijación transescleral de las hápticas sin suturas. El cirujano determina cuándo, dónde y cómo, además del tipo de lente a implantar. Se presenta un paciente con una afaquia traumática del ojo izquierdo, con agudeza visual sin corrección de cuenta dedos a un metro y refracción dinámica de +8,00 dioptrías con agudeza visual mejor corregida de 0,8 por cartilla de Snellen. Tensión ocular de 16 mmHg. En el examen biomicroscópico con lámpara de hendidura del ojo izquierdo se observó midriasis traumática. Se le realizó examen con biomicroscopia indirecta y resultó sin alteraciones. Se implantó el lente intraocular de tres piezas (Tecnis ZA9003) de la cámara posterior y se fijaron las hápticas a la esclera sin utilizar suturas. Al mes de la cirugía la agudeza visual mejor corregida fue la unidad de visión(AU)


Surgical aphakia correction is based on several techniques allowing to fix intraocular lenses in the posterior chamber, sutured to the ciliary sulcus or by sutureless transcleral fixation of the haptics. The surgeon will decide when, where and how, as well as the lens type to implant. A case is presented of a male patient with traumatic aphakia of his left eye, finger counting uncorrected visual acuity at one meter and dynamic refraction of +8.00 diopters with best corrected visual acuity of 0.8 by the Snellen chart. Ocular tension was 16 mmHg. Biomicroscopic slit lamp examination of the left eye found traumatic mydriasis. Indirect biomicroscopy did not find any alteration. A three-piece intraocular lens (Tecnis ZA9003) was implanted in the posterior chamber, fixing the haptics to the sclera without the use of sutures. One month after surgery, best corrected visual acuity was the vision unit(AU)

RESUMO

PURPOSE: The aim was to report 2 unusual cases of optic disc hemorrhage (DH) occurring following pharmacologic mydriasis. OBSERVATION: A 78-year-old woman and 60-year-old man with primary open angle glaucoma developed optic DHs shortly after pupillary dilation. CONCLUSION AND IMPORTANCE: Cycloplegia may cause subtle shifts in vitreous and lamina cribrosa position that may result in the formation of optic DHs in susceptible glaucomatous eyes.
