ABSTRACT
To introduce a case of neglected advanced retinoblastoma. A 6 year old girl presented with a large orbital mass enlarging over her cheek on the right side. She underwent exenteration and histopathologic evaluation. A diagnosis of retinoblastoma was made with free margins. This case presents a rare form of retinoblastoma with extensive local progression but no metastasis or CNS involvement. Although most of the retinoblastoma cases are diagnosed before the age of 3 years, there are neglected cases who present at advanced stages
ABSTRACT
To evaluate the effect of early drainage of delayed suprachoroidal hemorrhage [SCH] after glaucoma surgery. These study reports seven cases of delayed supra-choroidal hemorrhage following glaucoma surgery managed with early drainage. In this series instead of waiting for 7 to 14 days for clot lysis, the SCH was drained from the suprachoroidal space immediately after diagnosis. Seven eyes of 7 patients with delayed SCH including 4 men and 3 women were enrolled in the study. Median age was 42.57 +/- 29.61 years and mean follow up duration was 21.43 +/- 13.35 months. Immediately after diagnosis, choroidal tap and anterior chamber reformation were performed for all the patients. Intraocular pressure [IOP] decreased significantly after intervention. At final follow up, mean visual acuity was 1.08 +/- 0.31 LogMAR. Immediate surgical drainage of suprachoroidal hemorrhage seems to be an effective and safe method for treatment of delayed SCH; and it may decrease the inflammation from the entrapped blood in suprachoroidal space and reduce complications and additional procedures. Larger trials are recommended for further evaluation
ABSTRACT
To compare visual outcomes and changes in high-order aberrations [HOAs] following conventional versus customized photorefractive keratectomy [PRK]. In this clinical trial, 58 eyes of 29 patients underwent myopic PRK using the Technolas 217Z excimer machine. After comprehensive evaluation for refractive surgery, one eye of each participant randomly received conventional ablation [group 1] while customized treatment was performed in the fellow eye [group 2]. Changes in postoperative visual acuity, cycloplegic refraction, and contrast sensitivity function [CSF], HOAs and subjective complaints of halos and glare were compared between the two groups. Mean subject age was 26.7 +/- 6.0 years. Mean preoperative cycloplegic spherical equivalent refractive error and refractive astigmatism were -4.92 +/- 1.6 0 and 0.91 +/- 1.0 0, respectively. There was no significant difference between the two groups in terms of preoperative HOAs and CSF. Mean follow-up period was 8.1 +/- 3.3 months. After the operation, total HOAs for 4 mm pupil was increased by 0.24 +/- 0.19 pm in group 1 and by 0.31 +/- 0.21 pm in group 2 [P<0.001]. Corresponding figures for 6 mm pupil were 0.34 +/- 0.23 [range -0.08 to 0.75] and 0.52 +/- 0.32 [-0.04 to 1.43] pm respectively [P=0.03]. The increase in postoperative HOAs was statistically significant in group 2 in the 6 mm zone [P=0.03] but not in the 4 mm zone [P=0.26]. CSF was reduced in both groups, but there was no significant difference between the study groups in terms of postoperative CSF and subjective complaints. HOAs significantly increased after PRK using conventional and customized ablation. The increase in HOAs after customized ablation was significantly greater than that after conventional ablation
ABSTRACT
Optic neuritis occurs in young patients, most often females, and presents as subacute monocular visual loss. Periocular pain, particularly with eye movement occurs in the majority of cases. The retrobulbar form occurs in 65% of cases and is associated with normal optic disc appearance at onset. The central visual field is usually affected and an RAPD and dyschromatopsia are present. Brain magnetic resonance imaging [MRI] is recommended in all cases of optic neuritis. Evaluation for periventricular white matter lesions is the single best test for assessing the risk of future multiple sclerosis [MS]. Typical idiopathic neuritis begins to show improvement within one month, the use of intravenous methylprednisolone 250 mg every 6 hours for 3 days, followed by oral prednisolone 1 mg/kg/ day for 11 days speeds recovery by 1 to 2 weeks. Oral prednisolone alone has shown no benefit, has been associated with an increased risk of recurrence and its use is not recommended
