A case of reverse amblyopia in a myopic anisometropic patient: an atypical presentation.

We herein report a case of a 4-year-old female patient who presented with anisometropic amblyopia with initial visual acuity recorded at 20/400 OD and 20/100 OS. The patient was recommended for patching. Eighteen months later, the patient presented with visual acuity of 20/60 OD and 20/80 and reverse amblyopia was noted. In settings of amblyopia, where alternate patching may be used, it is most likely that reverse amblyopia, if present, will affect the more myopic eye. However, unexpectedly, in this case, reverse amblyopia occurred in the less myopic eye. With discontinuation of occlusion therapy and continued use of optical correction, the patients reverse amblyopia resolved and the visual equity equalized. To our knowledge, this is the first case described in the literature demonstrating such an occurrence. Awareness of this rare presentation by clinicians is of great importance to aid in correctly diagnosing and treating such patients.

Retinocytoma: A Case Series.

Retinoblastoma is the most common ocular malignancy in children, considered fatal without treatment. Retinocytoma is a rare benign clinical entity of retinoblastoma that shows signs of tumor regression. The clinical presentation of retinocytoma usually includes a gray translucent mass, intralesional calcification, and retinal pigment epithelial alteration, along with the presence of chorioretinal atrophy. We report two cases of retinocytoma in patients presenting with strabismus in the Eastern Province of Saudi Arabia.

Outcomes of Consecutive Exotropia Surgery at a Tertiary Eye Hospital in Saudi Arabia.

Purpose: This study aimed to evaluate surgical outcomes, compare success rates, and identify potential risk factors for failure of various surgical procedures for consecutive exotropia. Patients and Methods: This retrospective cohort study was conducted at a tertiary eye hospital in Saudi Arabia and included patients with consecutive exotropia treated between 2007 and 2020. Patients with a follow-up of <3 months were excluded. The type of surgery performed was based on surgeon experience and factors, such as the angle of deviation, adduction limitation, and intraoperative findings. Successful outcome was defined as a deviation of ≤10 prism diopters (PD) at the last follow-up visit. Results: A total of 59 patients were included in this study. Preoperatively, the mean near and distance deviations were 33 ± 14 PD and 32 ± 14 PD, respectively. Among the included patients, 27.1% underwent medial rectus advancement with or without resection, 28.8% underwent lateral rectus recession, and 44.1% underwent combined surgery. At 12 months postoperatively or the last follow-up visit, the overall success rate of distance-deviation correction and near-deviation correction were 80.6% and 67.8%, respectively. Success rates of different surgeries were not significantly different. The severity of amblyopia and number of muscles operated on did not influence the success rate. Conclusion: Medial rectus advancement and combined medial rectus advancement with lateral rectus recession were associated with better surgical outcomes than lateral rectus recession alone, although the difference was not statistically significant. The only factor that negatively affected the outcome was a high preoperative near angle of deviation.

Ophthalmia nodosa secondary to multiple intraocular caterpillar hairs in a 2-year-old girl.

A 2-year-old girl presented with pain, itching, photophobia, and tearing in her left eye. These symptoms started after contact with a caterpillar. The patient was initially taken to another hospital, where the local ophthalmologist prescribed topical prednisolone acetate 1%, a topical antibiotic, and cyclopentolate 1% eye drops. However, 3 weeks later, the patient presented to our hospital with no symptomatic improvement. Slit-lamp examination showed moderate conjunctival injection and diffuse superficial punctate corneal epithelial erosions with numerous caterpillar hairs embedded in the bulbar and tarsal conjunctiva, and in the superficial and deep corneal stroma, extending into the anterior chamber (AC). In addition, the AC had 2+ cells with caterpillar hairs on the iris surface. The lens was clear, and the fundus examination was normal. The patient underwent AC wash and setae removal under general anesthesia; this was repeated 4 months later when symptoms recurred owing to retained setae. There was no evidence of any additional setae or ocular inflammation in 8 months of follow-up, and symptoms resolved completely. Caterpillar hairs can migrate intraocularly and induce an ocular inflammatory response. Immediate and thorough irrigation, continued scrupulous examinations for any retained setae, and meticulous setae extraction are crucial for treating this condition.

Acute subconjunctival pigmentation with an underlying ciliary body mass: An unusual case presentation.

Intraocular melanocytoma is a rare slowly growing benign tumor that may occur anywhere along the uveal tract including the ciliary body but is more commonly found near the optic disc. It is darkly pigmented and may exhibit fast growth and possibly malignant transformation. Ciliary body (CB) melanocytoma is rare and often misdiagnosed as a melanoma. We are reporting a case of CB melanocytoma in a 74-year old lady with unusual initial presentation of an acute onset of subconjunctival pigmentation and extra-scleral extension of the melanocytoma with coarse melanin granules. The diagnosis of melanocytoma was confirmed by histopathological examination of the prolapsed tissue and by ultrastructural studies. Literature review of similar cases is also summarized.

Outcomes of Scleral-fixated Intraocular-lens in Children with Idiopathic Ectopia Lentis.

PURPOSE: The purpose of the study was to review the safety and stability of scleral-fixated intraocular lens (IOL) 2 years after implantation in children with idiopathic ectopia lentis (EL). METHODS: This retrospective case series enrolled children with EL managed between 2011 and 2015 at a tertiary eye hospital in the eastern of Saudi Arabia. Data were collected on age, gender, vision, isolated or syndromic pathology, intraoperative and postoperative complications, spherical equivalent refraction, and final best-corrected visual acuity (BCVA). RESULTS: The series included 18 eyes of 11 children with EL (6 males and 5 females). There were 7 bilateral and 4 unilateral cases. The median age was 3.5 years (25% quartile 1 year; range: 1-8 years). Preoperatively, fixation was absent in 3 eyes, 8 eyes were fixating but vision could not be recorded. In the remaining seven eyes, median distant visual acuity was 0.1 (25% quartile: 0.08). The median postoperative follow-up was 24 months (25% quartile, 7 months). Complications included two eyes with iris capture and one eye with lens subluxation requiring re-implantation. Postoperative BCVA was better than 20/60 in 15 (83%) eyes. At last follow-up, 6 eyes required myopic correction, 1 eye was emmetropic, and 11 eyes were hypermetropic. One eye with glaucoma was managed medically. CONCLUSION: Scleral fixated IOL in eyes of young children with EL had good visual outcomes and high stability. However, there is a high incidence of residual refractive error.

Secondary implantation of implantable collamer lens (ICL) for correction of anisometropic hyperopia in a 3-year-old pseudophakic child.

We report the first case of secondary implantation of implantable collamer lens (ICL) for correction of anisometropic hyperopia in a 3-year-old pseudophakic child. The ICL implantation was considered in our patient due to parental noncompliance for contact lens and spectacles use for one year. In terms of efficacy, the preoperative refractive error of +7.00-1.75 diopter (D) reduced to +1.00-1.75 D. The uncorrected distance visual acuity (UDVA) significantly improved from 20/400 (preoperatively) to 20/50 (postoperatively). In terms of safety, after an uneventful implantation surgery, the ICL was well tolerated, and remained well centered, with no serious postoperative complications encountered over a 22-month follow-up.

Implantation of spherical and toric copolymer phackic intraocular lens to manage amblyopia due to anisometropic hyperopia and myopia in pediatric patients.

PURPOSE: To evaluate the safety and efficacy of implantation of the Visian Implantable Collamer Lens phakic intraocular lens (pIOL) (spherical and toric models) for management of amblyopia due to anisometropic hyperopia and myopia in children. DESIGN: Retrospective case series. SETTING: Tertiary care eye specialty hospital, Dhahran, Saudi Arabia. METHODS: Eyes of patients who underwent the implantation of the pIOL for refractory anisometropic amblyopia were identified. None of the patients were compliant with spectacle/contact lens correction. Preoperative and postoperative clinical evaluation included visual acuity, cycloplegic refraction, slitlamp microscopy, intraocular pressure, orthoptic evaluation, anterior chamber depth, and ICL vault. RESULTS: A total of 11 eyes (9 myopic, 2 hyperopic) of 11 patients aged 5 to 15 years were identified. Of the 9 myopic eyes, 6 eyes received spherical ICLs and 3 received toric ICLs. Both hyperopic eyes received spherical ICLs. Preoperatively, the mean cycloplegic refractive spherical equivalent (CRSE) was -11.07 D (range -7.75 to -21.88 D) in myopic eyes, and +8.75 D (range +8.63 to +8.87 D) in hyperopic eyes. The mean corrected distance visual acuity (CDVA) was 20/171 (range 20/40 to 20/400) in myopic eyes, and 20/130 (range 20/60 to 20/200) in hyperopic eyes. At a mean follow-up of 16.8 months (in myopic eyes), the mean CRSE was -1.40 D (range 0 to -2.25 D), and mean CDVA was 20/51 (range 20/20 to 20/100). In hyperopic eyes, at a mean follow-up of 15 months, the mean CRSE was +1.82 D (range +1.75 to +1.88 D) and the CDVA had improved to 20/25 in both eyes. Although complications occurred in the 2 hyperopic eyes, the complications were either temporary or visually insignificant and did not necessitate reoperation or ICL explantation. CONCLUSION: ICL implantation may be considered a safe and effective treatment option for refractory amblyopia due to anisometropic hyperopia or myopia in children who are noncompliant with conventional therapy.
