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.

OBJECTIVES: Dysthyroid optic neuropathy (DON) is a class of diseases that makes seriously endanger to the vision of patients with thyroid-associated ophthalmopathy. This study aims to observe the visual function changes in patients with DON, and to evaluate the diagnostic value of indicators diagnosing DON. METHODS: A retrospective study was conducted on 98 eyes of 49 patients with dysthyroid optic neuropathy (DON) who were treated in Xiangya Hospital of Central South University from January 2017 to December 2019. All patients were received the examination of best corrected visual acuity (BCVA), Humphrey visual field, visual evoked potential (VEP), and contrast sensitivity. Ninety-eight eyes were divided into a DON group (45 eyes) and a non-DON group (53 eyes). T-test was used to compare the related indicators between the 2 groups. The sensitivity and specificity of each indicator were analyzed by receiver operating characteristic (ROC) curve. RESULTS: The BCVA and visual field index (VFI) of the DON group were significantly lower than those of the non-DON group (all P<0.05). The mean deviation (MD) and pattern standard deviation (PSD) of the DON group were significantly higher than those of the non-DON group (all P<0.05). The low frequency contrast sensitivity (CSL), medium frequency contrast sensitivity (CSM), and high frequency contrast sensitivity (CSH) of the DON group were significantly lower than those of the non-DON group (all P<0.05), with CSH being particularly prominent. Compared with the non-DON group, at spatial frequencies of 15°, 30°, and 60°, the amplitude of N135 wave was significantly reduced, and the latency of N75 wave, P100 wave, and N135 wave was significantly prolonged in the DON group (all P<0.05); at spatial frequencies of 15° and 30°, the amplitude of P100 wave was significantly reduced in the DON group (P<0.05). The ROC curve analysis results showed that the area under the curve (AUC) of VFI, CSL, CSM, CSH and 15° P100 amplitude diagnosing DON were 0.812, 0.841, 0.880, 0.784, and 0.791, respectively, with CSM possessing the highest sensitivity and specificity. CONCLUSIONS The visual function of patients with DON is decreased. VFI, contrast sensitivity of low, medium, and high frequency, and 15° P100 wave amplitude might be effective indicators for early diagnosis of DON.

A 56-year woman presented eyeball pain and blurred vision. MRI revealed a small well-delineated solid tumor in the apex of right orbit with optic nerve compression. Intraoperatively, the tumor was found very fibrous, hypervascular and adhesive to surrounding structures. The tumor was completely removed with the combination of endoscopic and microscopic technique. Patient experienced transient oculomotor nerve palsy, which completely recovered 3 months after surgery. Herein we report a rare case of angioleiomyoma in the orbital apex.

PURPOSE: We report an unusual case of Leber hereditary optic neuropathy presenting with optic disc hyperfluorescence. CASE SUMMARY: A 17-year-old male with sequential painless visual loss 3 weeks apart affecting first the left and then the right eye presented to our neuro-ophthalmology clinic. His best-corrected visual acuity was counting fingers in the right eye and 0.32 in the left eye. Fundus examination showed mild optic disc edema and hyperemia in both eyes, which were worse in the right eye. Fluorescein angiography revealed dye leakage from the right optic disc in the late phase. The results of magnetic resonance imaging of the brain and spinal cord were normal, and lumbar puncture study was unremarkable. Mitochondrial DNA sequencing revealed a pathognomonic 11778 mutation for Leber hereditary optic neuropathy. His vision deteriorated to 0.03 in both eyes 6 months later, but slowly started to improve 11 months after onset. At 2 years, his corrected visual acuity was 0.2 in both eyes. CONCLUSIONS: To our knowledge, this is the first report of optic disc hyperfluorescence in Leber hereditary optic neuropathy. This finding suggests that this mitochondrial optic neuropathy can masquerade as optic neuritis.

PURPOSE: To investigate the types and clinical features of neurological diseases after head trauma. METHODS: From March 2010 to December 2018, a total of 177 patients were enrolled in this study. We retrospectively reviewed the clinical features of neurological ophthalmic diagnoses and frequencies, the types of head injuries, and the prognoses. RESULTS: Cranial nerve palsy was the most common (n = 63, 35.6%), followed by traumatic optic neuropathy (n = 45, 25.4%), followed by optic disc deficiency, ipsilateral visual field defect, Nystagmus, skewing, ocular muscle paralysis between nuclei, and Terson syndrome. Neuro-ophthalmic deficits occurred in relatively strong traumas accompanied by intracranial hemorrhage or skull fracture. However, convergence insufficiency and decompensated phoria occurred in relatively weak trauma such as concussion. The prognoses of the diseases were poor (p < 0.05) for traumatic optic neuropathies and visual field defects. The prognoses of neurological diseases were poor if accompanied by intracranial hemorrhages or skull fractures (p < 0.05). CONCLUSIONS: After head trauma, various neuro-ophthalmic diseases can occur. The prognosis may differ depending on the type of the disease, and the strength of the trauma may affect the prognosis.

PURPOSE: We report two patients diagnosed with a sinus thrombosis with papillary edema. CASE SUMMARY: Case 1 was a 27-year-old male who presented with complaints of headache and vomiting for 2 months and blurred vision in both eyes. The best-corrected visual acuity (BCVA) was 1.0 in the right eye and 1.0 in the left eye. A visual field (VF) examination revealed a binocular peripheral VF defect and optical coherence tomography (OCT) and a fundus examination indicated optic disc swelling in both eyes. Brain magnetic resonance imaging (MRI) showed no specific finding but magnetic resonance venography revealed filling defect signs in the transverse sinus and a cerebrospinal fluid examination indicated elevated intracranial pressure (ICP). Case 2 was a 54-year-old female who came to our hospital with suspicion of bilateral optic disc swelling. The BCVA was 0.9 in the right eye and 1.0 in the left eye. A VF examination revealed an inferior-temporal VF defect and blind spot enlargement in the right eye. OCT and a fundus examination showed optic disc swelling in both eyes. Brain MRI showed no specific finding but magnetic resonance venography revealed a decrease in blood flow in the transverse sinus, sigmoid sinus. A cerebrospinal fluid examination indicated elevated ICP. CONCLUSIONS: In the case of optic disc swelling in both eyes, a secondary cause of ICP elevation and the possibility of optic disc swelling due to sinus thrombosis should be considered, and brain MRI and venography are needed to distinguish these possibilities.

" 's triple nine needling therapy" is the crucial acupuncture prescription in treatment of eye diseases in 's academic school of ophthalmology. " 's triple nine needling therapy" includes the three points near to the eyes, the three groups of points for penetrating acupuncture around the eyes and the acupoint selection based on the general differentiation of syndrome. In this paper, the acupoint selection and the thinking of acupoint combination were introduced in the treatment of optic nerve disease on the base of the theory of " 's triple nine needling" prescription. The specific needling manipulations at different regions involved in the triple needling procedure were explained in detail. It is proposed that the acupoints are combined and the correct needling manipulations selected rationally in compliance with the illness condition and the syndrome characteristics to ensure maximally the clinical effects of " 's triple nine needling therapy".

PURPOSE: We sought to investigate the effects of Graves' orbitopathy (GO) and orbital decompression on lamina cribrosa depth (LCD) using spectral-domain optical coherence tomography. METHODS: Forty eyes that underwent orbital decompression to relieve compressive optic neuropathy or correct disfiguring exophthalmos in the context of GO were included. Subjects were imaged with spectral-domain optical coherence tomography before surgery and at 1 and 3 months after surgery, at which the examiner measured the LCD (distance from the anterior surface of the lamina cribrosa to the Bruch membrane opening line) and peripapillary retinal nerve fiber layer thickness. Subjects were divided into two groups—a muscle-dominant group composed of patients who had extraocular muscle enlargement on preoperative orbital computed tomography scan and a fat-dominant group composed of patients who did not show extraocular muscle enlargement on preoperative orbital computed tomography scan—and subgroup analysis was performed. Preoperative and postoperative intraocular pressure, exophthalmos, LCD, and retinal nerve fiber layer thickness were evaluated. RESULTS: At baseline, LCD was remarkably shallower in the muscle-dominant group than in the fat-dominant group (95% confidence interval, p = 0.007). In the muscle-dominant group, LCD showed no definite change after surgery. However, the fat-dominant group showed temporary posterior displacement of the lamina cribrosa at 1-month postoperation that was reversed to baseline at 3 months postoperation (95% confidence interval, p < 0.01). CONCLUSIONS: The lamina cribrosa was anteriorly displaced preoperatively, and its position was nearly unchanged after the surgery, especially in association with extraocular muscle enlargement. An enlarged extraocular muscle could reduce the pressure-relieving effect of orbital decompression around the scleral canal in patients with GO.

PURPOSE: We investigated changes in the thickness of the peripapillary retinal nerve fiber layer (RNFL) following the onset of an epiretinal membrane (ERM) in glaucoma patients. METHODS: Among regularly monitored glaucoma patients, patients with a newly diagnosed ERM were consecutively enrolled. Before and after the onset of ERM, the RNFL thickness was measured using spectral domain optical coherence tomography, and a visual field examination was performed using a Humphrey field analyzer. Changes in RNFL thickness parameters and global indices of the visual field analyzer were assessed. RESULTS: In a total of 28 eyes from 28 patients, the average RNFL thickness increased by a mean of 4.0 ± 7.4 µm (p = 0.009) after ERM onset. There was an increase in the superior, nasal, and temporal quadrant RNFL thicknesses, and the change in the temporal RNFL thickness was significant (14.4 ± 21.2 µm, p < 0.001). However, the inferior RNFL thickness decreased by −0.6 ± 7.5 µm (p = 0.116). In the visual field examination, the mean deviation decreased significantly by −0.8 ± 1.7 dB (p = 0.038), from −14.6 to −15.4 dB. CONCLUSIONS: A significant increase in average RNFL thickness was detected following ERM onset in glaucoma patients, although there was deterioration of the mean deviation in the visual field. When ERM occurs in glaucoma patients, clinicians should be aware that RNFL thickness measurements obtained with a spectral domain optical coherence tomography may underestimate the status of glaucomatous optic neuropathy.
