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.

PURPOSETraumatic optic neuropathy (TON) is a serious complication of head trauma with the incidence rate of 0.5%-5%. The aim of this study was to investigate the therapeutic efficacy of endoscopic decompression of the optic canal for optic nerve injuries.

METHODSIn this study, 11 patients treated in our hospital from January 2009 to January 2015 with the visual loss resulting from TON were retrospectively reviewed for preoperative vision, visual evoked potential (VEP) scan, surgical approach, postoperative visual acuity, complications, and follow-up results.

RESULTSAll these patients received endoscopic decompression of the optic canal. At the 3-month follow- up, the visual acuity improvement rate of the 11 patients was 45.5%. The vision acuity of 2 cases improved from hand movement to 0.08 and 0.3 after operation. Another patient's vision acuity returned to 0.05 compared to light sensation preoperatively. Two cases had finger counting before surgery but they had a vision acuity of 0.4 and light sensation respectively after surgery. However, the other 6 cases' vision did not improve after surgery.

CONCLUSIONEndoscopic decompression of the optic canal is an effective way to cure TON. VEP could be used as an important reference for preoperative and prognosis evaluation. Operative time after trauma is only a relative condition that may affect the therapeutic effect of optic canal decompression. Poor results of this procedure may be related to the severity of the optic nerve injury.

OBJECTIVETo observe the treatment and prognosis of optic nerve invasion in retinoblastoma (RB).

METHODThe children who had been diagnosed with unilateral RB and had received enucleation from January 2006 to December 2013 in our hospital were recruited. Tumor extension into the optic nerve were disclosed. Optic nerve involvement was classified into four grades according to the degree of invasion. Grade I is superficial invasion of the optic nerve head only, grade II is involvement up to and including the lamina cribrosa, grade III is involvement beyond the lamina cribrosa, and grade IV is involvement up to and including the surgical margin. Grade I and II are called invasion of the optic nerve before the sieve plate. Grade III and IV are called invasion of the optic nerve after the sieve plate. Other high-risk factors included extensive invasions of the choroid, sclera, anterior chamber, iris, and ciliary body. They were divided into two groups according to whether the merger of other high histopathologic risk factors. Treatment was delivered accordingly, and the prognosis of different degrees of optic nerve invasion was observed. The subjects were followed up for 6 months to 7 years (average: 43 months).

RESULTThere were 465 subjects in this study, including 279 boys and 186 girls. The right eye was affected in 260 patients and the left eye in 205 patients. The average time from onset of symptoms to visit was 2.7 months (range 1 day-24 months). Twenty-five patients died, resulting in an overall survival rate of 94.6%. The mortality rate of patients with optic nerve involvement with grade I was 0.4%, grade II was 1.0%, grade III was 8.7% was and grade IV was 60.9%. Of the 338 with invasion of the optic nerve before the sieve plate, two died of recurrence, with a survival rates of 99.4% (336/338). Of the 127 patients who had invasion of the optic nerve after the sieve plate, twenty-three died of recurrence, with a survival rate of 81.9% (104/127) , the difference was statistically significant (χ² = 52.299, P = 0.000). A total of 379 patients did not have any other merged pathology high-risk factors, 8 died, the mortality rate was 2.1%. Of the 86 patients who had complicated with other high-risk factors, 17 died, the mortality rate was 19.8%, the difference was statistically significant (χ² = 42.955, P = 0.000). Of the 338 patients, 304 had invasion of the optic nerve before the sieve plate had not merged other pathology high-risk factors, none died, of the 34 patients who had complicated with other pathology high-risk factors, 2 had died, the mortality rate was 5.9%, the difference was statistically significant (P = 0.010). Of the 127 patients with invasion of the optic nerve after the sieve plate, 76 had not complicated with other pathological high-risk factors, 9 of whom had died, the mortality rate was 11.8%, 51 had complicated with other pathological high-risk factors, 14 of whom had died, the mortality rate was 27.5%, outcomes did significantly differ between the two subgroups (χ² = 5.014, P = 0.025). Cox multivariate analysis showed that invasion of the retrolaminar optic nerve, surgical margin of the optic nerve and sclera were influential factors of colorectal cancer.

CONCLUSIONPatients with optic nerve invasion have an excellent outcome with current therapy. But for those whose resection margin was invaded, which has a high incidence of recurrence, chemotherapy is recommended for patients with postlaminar optic nerve involvement.

OBJECTIVE: To analyze the long-term efficacy of nasal endoscopic opticnerve decompression for traumatic optic neuropathy(TON) and to explore its possible influencing factors. METHOD: To summarize the clinical data of 39 cases underwent transnasal decompression, which were followed-up for more than 1 year. The data, including optic canal CT scanning, flashed-elicited visual-evoked potential (FVEP), preoperational vision and visual field examination were reviewed. Nasal endoscopic optic nerve decompression was preformed. Whether or not optic nerve sheath incision decided to perform was according to preoperative CT and situations in operation. Postoperative follow-up including vision, visual field, funduscopy, nasal endoscopy were performed. RESULT: Total efficacy rate was 30. 77% (12/39), inefficacy rate was 69. 23%(27/39). The efficacy rate was 85. 71% with better than nolight perception, and the efficacy rate was 18. 75% with nolight perception, the clinical effect in the group of preoperative better than nolight perception was better than that of nolight perception, the difference was statistically significant (P<0. 05). The efficacy rate was 34. 38% with duration of less than 7 days from the traumatic point to the operation point, and the efficacy rate was 14. 29% for more than 7 days, but the difference was not statistically significant (P> 0. 05). The efficacy rate was 26. 32% with optic nerve sheathincision, while the efficacy rate was 35. 00% without optic nerve sheath incision, and there was no statistically significant difference (P>0. 05); Postoperative vision tended to stabilize until about 6 months post-operation, without complications. CONCLUSION The long-term efficacy of nasal endoscopic opticnerve decompression for TON was certain; The efficacy with preoperative residual vision was better than that of nolight perception, the factor of long or short duration from the trauma point to the operation point and the factor of optic nerve sheath incision didn't influence long curative effect. To avoid the secondary damage to the optic nerve after trauma was the key to increase long curative effect in TON.

PURPOSE: To evaluate the effect of pattern scan laser (PASCAL) photocoagulation on peripapillary retinal nerve fiber layer (RNFL) thickness, central macular thickness (CMT), and optic nerve morphology in patients with diabetic retinopathy. METHODS: Subjects included 35 eyes for the PASCAL group and 49 eyes for a control group. Peripapillary RNFL thickness, cup-disc area ratio and CMT were measured before PASCAL photocoagulation and at 2 and 6 months after PASCAL photocoagulation in the PASCAL or control groups. RESULTS: The average RNFL thickness had increased by 0.84 microm two months after and decreased by 0.4 microm six months after PASCAL photocoagulation compared to baseline, but these changes were not significant (p = 0.83, 0.39). The cup-disc area ratio was unchanged after PASCAL photocoagulation. CMT increased by 18.11 microm (p = 0.048) at two months compared to baseline thickness, and partially recovered to 11.82 microm (p = 0.11) at six months in the PASCAL group. CONCLUSIONS: PASCAL photocoagulation may not cause significant change in the peripapillary RNFL thickness, CMT, and optic nerve morphology in patients with diabetic retinopathy.

A 69-year old man presented to us with decreased vision in his right eye and a relative afferent pupillary defect. Under the presumption that he was suffering from retrobulbar optic neuritis or ischemic optic neuropathy, visual field tests were performed, revealing the presence of a junctional scotoma. Imaging studies revealed tumorous lesions extending from the sphenoid sinus at the right superior orbital fissure, with erosion of the right medial orbital wall and optic canal. Right optic nerve decompression was performed via an endoscopic sphenoidectomy, and histopathologic examination confirmed the presence of aspergillosis. The patient did not receive any postoperative antifungal treatment; however, his vision improved to 20 / 40, and his visual field developed a left congruous superior quadrantanopsia 18 months postoperatively. A junctional scotoma can be caused by aspergillosis, demonstrating the importance of examining the asymptomatic eye when a patient is experiencing a loss of vision in one eye. Furthermore, damage to the distal optic nerve adjacent to the proximal optic chiasm can induce unusual congruous superior quadrantanopsia.

OBJECTIVE: To investigate the advantages of image guidance system in endoscopic optic nerve decompression of traumatic occlusion optic neuropathy affiliated with cerebrospinal rhinorrhea. METHOD: Retrospective review of 15 traumatic occlusion optic neuropathy affiliated with cerebrospinal rhinorrhea at our department between June 2006 and June 2010. Witch were performed endoscopic optic nerve decompression and cerebrospinal rhinorrhea euplastic by image guidance system. RESULT: After 3 months to 1 year follow-up, All the cases with cerebrospinal rhinorrhea euplastic were successful. Two cases recovered to 0.3-0.6 in visual activity. Two cases to 0.1-0.3. One case was less than 0.1. Two cases could see hand movement and 2 cases had light perception. Total effective rate was 60 percent (9/15). CONCLUSION Image guidance system combined with endoscopy provides accurate localization and identifies the operative borders and critical anatomical structure of skull base, optic nerve and internal carotid artery,and also clearly indicate their adjacent relations,also decreases surgical invasions and complications. Image guidance system can improve the accuracy and safety, particularly in local anatomic structure due to the trauma caused by changes in the relationship. It is a safety and effective therapy method.
