BACKGROUND

Corticosteroids have been used in ophthalmology for its potent anti-inflammatory and immunosuppressive actions. Although the role of corticosteroid treatment is pivotal in the treatment of numerous inflammatory diseases and as postoperative management of patients who undergo ocular surgeries, intraocular pressure (IOP) elevation has been a significant ocular side effect that could result after steroid use. Evaluating the changes in IOP in pediatric eyes will provide early detection and timely intervention to prevent glaucomatous optic neuropathy.

OBJECTIVE

This study aimed to determine the incidence of IOP elevation among pediatric patients given corticosteroids after strabismus surgery in a tertiary hospital in Manila, Philippines.

METHODS

This is a single-center, retrospective, observational study that employs review of the clinical records of pediatric patients who underwent strabismus surgery between January 2015 and December 2022. This study was conducted last February to November 2023. Data were gathered and descriptively summarized regarding patient demographics, ophthalmologic diagnosis, type of strabismus surgery performed, preoperative and postoperative IOP readings, frequency and duration of postoperative topical steroid use, and treatment received and response to elevated IOP.

RESULTS

Forty-five (28.48%) out of the 158 pediatric patients who had strabismus surgery during the study period met the inclusion criteria for the study. The mean age of pediatric patients was 11.38 ± 5.28 years (range 2-18 years old). There were more males (55.6%) than females. All patients were administered Tobramycin + Dexamethasone eyedrops, ointment or both. The baseline, peak, and net change in IOP were 13.5 ± 2.7 mmHg, 23.1 ± 8.8 mmHg and 10 ± 8.4 mmHg respectively. IOP increased in thirty-seven (82.2%) of the patients from baseline, and 21 (56.7%) of them had a considerable rise. For most patients with considerable rise of IOP, topical steroid medication was either stopped or immediately tapered off. Nine patients received topical IOP-lowering medicine, and most of them returned to normal IOP levels two months following surgery. After then, topical IOP-lowering drugs were stopped.

CONCLUSION

IOP elevation following strabismus surgery was frequently associated with topical steroid usage, and most patients experienced considerable IOP elevation. It is highly advised to closely monitor IOP following strabismus surgery, particularly in children receiving topical steroid treatment.

In this study, we explored the neural mechanism underlying impaired stereopsis and possible functional plasticity after strabismus surgery. We enrolled 18 stereo-deficient patients with intermittent exotropia before and after surgery, along with 18 healthy controls. Functional magnetic resonance imaging data were collected when participants viewed three-dimensional stimuli. Compared with controls, preoperative patients showed hypoactivation in higher-level dorsal (visual and parietal) areas and ventral visual areas. Pre- and postoperative activation did not significantly differ in patients overall; patients with improved stereopsis showed stronger postoperative activation than preoperative activation in the right V3A and left intraparietal sulcus. Worse stereopsis and fusional control were correlated with preoperative hypoactivation, suggesting that cortical deficits along the two streams might reflect impaired stereopsis in intermittent exotropia. The correlation between improved stereopsis and activation in the right V3A after surgery indicates that functional plasticity may underlie the improvement of stereopsis. Thus, additional postoperative strategies are needed to promote functional plasticity and enhance the recovery of stereopsis.

BACKGROUND: Sevoflurane is widely used to anesthetize children because of its rapid action with minimal irritation of the airways. However, there is a high risk of agitation after emergence from anesthesia. Strabismus surgery, in particular, can trigger agitation because patients have their eyes covered in the postoperative period. The aim of this study was to determine whether or not esmolol and lidocaine could decrease emergence agitation in children. METHODS: Eighty-four patients aged 3 to 9 years undergoing strabismus surgery were randomly assigned to a control group (saline only), a group that received intravenous lidocaine 1.5 mg/kg, and a group that received intravenous esmolol 0.5 mg/kg and lidocaine 1.5 mg/kg. Agitation was measured using the objective pain score, Cole 5-point score, and Richmond Agitation Sedation Scale score at the end of surgery, on arrival in the recovery room, and 10 and 30 min after arrival. RESULTS: The group that received the combination of esmolol and lidocaine showed lower OPS and RASS scores than the other two groups when patients awoke from anesthesia (OPS = 0 (0-4), RASS = -4 [(-5)-1]) and were transferred to the recovery room (OPS = 0 (0-8), RASS = -1 [(-5)-3]) (P < 0.05). There was no significant difference in the severity of agitation among the three groups at other time points (P > 0.05). CONCLUSIONS: When pediatric strabismus surgery is accompanied by sevoflurane anesthesia, an intravenous injection of esmolol and lidocaine could alleviate agitation until arrival in the recovery room.

PURPOSE: To evaluate differences in self-identity in patients diagnosed with strabismus, patients who underwent strabismus surgery, and healthy control individuals. METHODS: Self-identity testing was done during a military service physical examination. There were three subject groups: subjects with strabismus (group 1), subjects who had undergone corrective strabismus surgery (group 2), and subjects free of strabismus (group 3). The self-identity test was comprised of six sub-sections (subjectivity, self-acceptance, future confidence, goal orientation, initiative, and familiarity). Statistical significance of the sub-sections was compared across the three groups. Correlations in age at the time of surgery and across the six sub-sections were investigated in group 2. RESULTS: A total of 351 subjects were enrolled in the study; 96 subjects were in group 1, 108 subjects were in group 2, and 147 subjects were in group 3. Significant differences were evident in subjectivity, self-acceptance, initiative and familiarity between groups 1 and 3. No significant differences were found between groups 2 and 3. In group 2, statistical significance was evident between age at surgery and initiative and familiarity (r = −0.333, p < 0.001; r = −0.433, p < 0.001, respectively). CONCLUSIONS: Self-identity is greater in non-strabismus subjects than strabismus subjects. Correction of strabismus may increase self-identity levels.

PURPOSE: To evaluate the efficacy and safety of customized orbital decompression surgery combined with eyelid surgery or strabismus surgery for mild to moderate thyroid-associated ophthalmopathy (TAO). METHODS: Twenty-seven consecutive subjects who were treated surgically for proptosis with disfigurement or diplopia after medical therapy from September 2009 to July 2012 were included in the analysis. Customized orbital decompression surgery with correction of eyelid retraction and extraocular movement disorders was simultaneously performed. The patients had a minimum preoperative period of 3 months of stable range of ocular motility and eyelid position. All patients had inactive TAO and were euthyroid at the time of operation. Preoperative and postoperative examinations, including vision, margin reflex distance, Hertel exophthalmometry, ocular motility, visual fields, Goldmann perimetry, and subject assessment of the procedure, were performed in all patients. Data were analyzed using paired t-test (PASW Statistics ver. 18.0). RESULTS: Forty-nine decompressions were performed on 27 subjects (16 females, 11 males; mean age, 36.6 +/- 11.6 years). Twenty-two patients underwent bilateral operations; five required only unilateral orbital decompression. An average proptosis of 15.6 +/- 2.2 mm (p = 0.00) was achieved, with a mean preoperative Hertel measurement of 17.6 +/- 2.2 mm. Ocular motility was corrected through recession of the extraocular muscle in three cases, and no new-onset diplopia or aggravated diplopia was noted. The binocular single vision field increased in all patients. Eyelid retraction correction surgery was simultaneously performed in the same surgical session in 10 of 49 cases, and strabismus and eyelid retraction surgery were performed in the same surgical session in two cases. Margin reflex distance decreased from a preoperative average of 4.3 +/- 0.8 to 3.8 +/- 0.5 mm postoperatively. CONCLUSIONS: The customized orbital decompression procedure decreased proptosis and improved diplopia, in a range comparable to those achieved through more stepwise techniques, and had favorable cosmetic results when combined with eyelid surgery or strabismus surgery for mild to moderate TAO.

Traumatic rupture of the superior oblique muscle is rare. We report a case of a 54-year-old man injured by the metal hook of a hanger, resulting in a rupture of the superior oblique muscle tendon. He complained of torsional diplopia when in the primary position. The distal margin of the superior oblique muscle was reattached to sclera 5 and 9 mm apart from the medial insertion of the superior rectus muscle. One week after the operation, torsional diplopia disappeared. However, a 4-prism diopter ipsilateral hypertropia was observed. Three months later, hypertropia gradually increased to 20 prism dioptors and the second operation was done to correct vertical diplopia.

BACKGROUNDThere is no large population-based study of the distribution and changing trend of strabismus surgeries in China. This study aimed to investigate the distribution and the changing trend of strabismus surgery in a tertiary hospital of China.

METHODSA retrospective study of all the strabismus surgeries performed in Beijing Tongren Eye Center from 2003 to 2012 was carried out. Characteristics analyzed included the type of strabismus, age, and gender.

RESULTSTotally 26 524 strabismus surgeries were performed in Tongren Eye Center during the 10-year period. The number of surgeries increased steadily from 1 507 in 2003 to 3 482 in 2008 and slightly decreased to 3 124 in 2009, but there was a sharp drop to 2 569 in 2010 and then kept relatively steady at 2 760 in 2011 and 2 463 in 2012. Intermittent exotropia (30.3%) was the most common among all kinds of strabismus. The number of strabismus surgeries performed on children under 12 years of age (43.60%) was significantly higher than those of the other age groups (P < 0.05). Unilateral superior oblique paralysis was the most common subtype of paralytic strabismus (8.64%).

CONCLUSIONSThe type distribution of strabismus surgery has changed during the recent decade. The age and type distribution of different strabismus remained basically constant, among which intermittent exotropia was the most common.

OBJECTIVE: To evaluate the oblique angle, diplopia and stereoacuity before and after rectus recession-suspension on posterior sclera surgery in patients with restrictive strabismus caused by thyroid associated ophthalmopathy (TAO). METHODS: Data from 18 patients (19 eyes) with restrictive strabismus caused by TAO, who underwent rectus recession-suspension on posterior sclera surgery from July 2010 to June 2013 in Xiangya Hospital, Central South University, were analyzed retrospectively. Eight patients (8 eyes) or 5 patients (5 eyes) with hypotropia were operated with inferior rectus recession or superior rectus recession. Two patients (2 eyes) with esohypertropia or 3 patients (4 eyes) with esotropia were operated with inferior rectus recession plus medial rectus recession or medial rectus recession. Two patients (1 hypotropia, 1 esotropia) underwent orbital decompression surgery before strabismus surgery. All patients were performed rectus recession-suspension on posterior sclera surgery, and the oblique angle, diplopia view and stereopsis test were examined before and after the operation. RESULTS: All patients were followed up for more than 6 months. The preoperative prism were 20(Δ)- 80(Δ) and postoperative prism were 2(Δ)-10(Δ). There was diplopia on the primary position before surgery in 16 patients. After surgery, the diplopia in 14 patients disappeared on the primary and 15° down gaze, and 2 patients had not diplopia on the primary position but residual diplopia on inferior field. Two patients had stereopsis before surgery, and the numbers of patients raised to 14 after surgery. Compared with pre-operation, changes of the above measured indexs in post-operation were significant difference (all P<0.05). CONCLUSION The rectus recession-suspension on posterior sclera surgery is effective to improve oblique angle and diplopia in restrictive strabismus caused by TAO, which can improve patient's living quality.
